Today, magnetic field inhomogeneity in high-field NMR machines is minimized by proper shimming of the machine and extensive dilution of the sample with deuteron solvents. Hence, the line width (LW) measurements of the NMR peaks are reliable for NMR studies. This study is aimed at examining the relationship between the crude oil properties and the LW values of the CH2 and CH3 peaks and the relationship between the LW of water in crude oil and the percentage of water. A set of 22 mixtures was prepared by adding 0.02 mL of each crude oil to each 0.98 mL of CDCl3. A suitable NMR spectrum, including the water peaks of the mixtures, was obtained with a spectrometer operating at 400 MHz. Paraffinic CH2 and CH3 peak LWs vary from well to well. Paraffinic CH3 LW decreases nearly linearly with American Petroleum Institute gravity. In addition, the LW of the water peak at 4.75 ppm is strongly related to the percentage of water in crude oil. The mixtures used in this study provide the appropriate NMR peaks for CH2, CH3, and water in crude oil. NMR peaks of water in crude oil were displayed for the first time in the high field. Some of the previous results obtained in the low-NMR field were found. Therefore, this study suggests an additional approach for high-field NMR studies in petroleum chemistry. [ABSTRACT FROM AUTHOR]

At night, clear pavement markings are essential for driver safety. Currently, markings visibility evaluation relies on the retroreflectivity, but the impact of line width is unclear. To quantify the impact of line width on visibility and to refine visibility evaluation methods, a driver visual detection experiment was designed using both qualitative and quantitative approaches. Twenty-four drivers of small vehicles were randomly recruited to participate in visual detection tests of a total of 54 white pavement markings (comprising 6 widths and 9 retroreflectivity levels) under the illumination of high beams, following the principle of using the “emergence point” as the critical state for assessing pavement marking visibility. This study indicated that widening pavement markings significantly enhances their visibility, particularly for markings with low retroreflectivity. A visibility evaluation model was established to quantify the impact of width and retroreflectivity on the visual distance of markings. The model confirms that widening markings can improve visibility, thereby reducing the required level of retroreflectivity. The research methodology and findings provide technical support for managers to more accurately assess nighttime safety visibility during pavement marking operation and maintenance.

In this paper, we present a new methodology for realizing highly integrated stretchable displays. By utilizing the sidewalls of wiring, it is possible to overcome the limitations of conventional structures and significantly reduce the width of the wiring while maintaining its resistance. The improved aspect ratio also enhances stretchability and the width of the wiring can be further reduced by adjusting its thickness. The developed stretchable wiring with the new structure stably withstands elongation and the resistance change is less than 2%, even after 1000 times repeated elongations with a 50% stretch. By using this wiring scheme, a high‐resolution array with 100 PPI was fabricated that stably stretched to 100%. [ABSTRACT FROM AUTHOR]

This article discusses the influence of 3D printing parameters, such as the filling density and angle, as well as the line width, on the mechanical properties of the samples made of polyethylene terephthalate glycol by FDM printing (fused deposition modeling). Equations have been derived for calculating the expected mechanical properties of items made of polyethylene terephthalate glycol (PET-G) under uniaxial tensile and static and impact bending conditions. The influence of variable FDM printing parameters on the formed level of product properties is demonstrated, which would allow selection of their values depending on the formulated tasks.

The line width of different line shapes is a very important parameter in absorption spectroscopy sensing techniques. Based on the high sensitivity and low noise properties of wavelength modulation spectroscopy, we report a novel line width measurement method. After theoretically proving the relationship between line width, modulation amplitude and the amplitude of the second harmonic at the center frequency, the absorption lines of CH4 near 6046.96 cm−1 and CO2 4989.97 cm−1 were chosen for simulation, and the relative errors of the line width between our method and theoretical data were kept at about 1%. A distributed feedback laser diode operating near 1653 nm with three different concentrations of CH4 was used for experimental validation, and the results were consistent with the numerical simulation. Additionally, since only the peaks of second harmonic need to be measured, the advantages of wavelength modulation can be utilized while reducing the difficulty of data acquisition.

One of the most used additive manufacturing methods in the market is fused filament fabrication (FFF) due to its affordability and ease of operation. However, identification of optimal processing parameters is still a challenge and can help to achieve desired results in parts made by FFF. This paper presents the influence of two process parameters, i.e. layer height and line width on FFF-printed thermoplastics. Premium PLA, Haydale's Synergy Graphene Enhanced Super Tough PLA, ABS Extrafill and ASA Extrafill have been manufactured and tested according to British and International standards for this study. An extensive comparative analysis has been provided where parts have been manufactured using Anet® ET4 Pro 3D printer with the four materials at five different line widths (0.2 mm, 0.4 mm, 0.6 mm, 0.8 mm, 1 mm) and four different layer heights (0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm). The study analyses the effects of line widths and layer heights on mass, dimensional accuracy, surface texture and mechanical properties of the four materials. Microstructural analysis has also been carried out to evaluate the fractured surfaces and to determine the impact of modifying the two processing parameters on failure modes. Results have shown the trade-offs that can be made with the different materials in terms of properties and manufacturing time by modifying the layer heights and line widths. Designers and manufacturers can use this comparative analysis amongst the four materials to identify the limitations with the default printing settings (0.2 mm layer height and 0.4 mm line width) on most 3D printers and achieve desired results by leveraging the layer heights and line widths.

Fused filament fabrication (FFF) is a widely used additive manufacturing process that can produce parts from thermoplastics. Its ease of operation and wide variety of materials make it a popular choice for manufacturing. To leverage such benefits, the commonly used thermoplastics (e.g., PLA and ABS) are impregnated with nanoparticles, short or continuous fibers, and other additives. The addition of graphene nanoplatelets to PLA makes for a high-quality filament possessing enhanced mechanical, electrical, and thermal properties. Even with the advancement in materials, the optimisation of the process parameter remains the most complex aspect for FFF. Therefore, this study investigates the influence of two under-researched and overlooked processing parameters (material extrusion rates and line widths) on commercially available graphene-enhanced PLA (GPLA). Nine different material extrusion rates (70% to 150%) and five different line widths (0.2 mm to 1 mm) were used to manufacture GPLA specimens using a low-cost, desktop-based 3D printer, as per British and international standards. The study analyses the influence of these two processing parameters on mass, dimensional accuracy, surface texture, and mechanical properties of GPLA specimens. A non-destructive test has also been conducted and correlated with three-point flexural test to establish its applicability in evaluating flexural properties of GPLA. The results how that small line widths provide more accuracy with longer print times whereas large line widths offer more strength with shorter printing times. Increase in material extrusion rates adversely affect the surface finish and hardness but positively influence the flexural strength of GPLA specimens. The study shows that the manipulation of material extrusion rates and line widths can help designers in understanding the limitations of the default printing settings (100% material extrusion rate and 0.4 mm line width) on most desktop 3D printers and identifying the optimal combination to achieve desired properties using the FFF process.

Nowadays, the attention in many industries is shifting towards the problem of waste overproduction and production of the waste in general. This study aimed to find an alternative approach to the production of packaging which will be environmentally friendly and at the same time optimal in terms of the print quality. This was accomplished by using the minimal needed amount of material for the production of packaging and adjusting the parameters of the flexographic printing process to achieve the desired visual impression of the print. The designed motive for the packaging was printed on five different recycled papers, following the guidelines of sustainable design. Printing was performed on each recycled paper with different printing pressures (50N, 150N, and 400N). Smoothness was measured on each paper; and for every printed sample, colorimetric measurements and thickness of the lines in positive and negative were measured. Print contrast for each print was calculated, and microscopy of fine printed elements was performed. All chosen papers except one had average smoothnes of up to 3.2 s (the smoothest paper had the average smootheness value of 54.72 s). Smoothness results influenced the printed line widths. Specifically, when increasing the printing pressure, a significant deformation of the line width has occured on all papers except the smoothest one (deformations of the lines printed in positive were up to 400 μm for rough papers compared to maximum of 60 μm for lines printed on the smoother paper). Similar results were obtained for the lines printed in negative. Furthermore, legibility of the printed typographic elements of 4pt size was significantly influenced by the smoothness of the paper. Elements printed on the smoothest paper have displayed the negligible deformations when changing the printing pressure. For other papers, elements in positive were optimally printed by 50 N pressure, and elements in negative by the pressure of 400 N. The results of this research have enabled the optimization of the flexographic printing process when using each of the five types of recycled papers. Furthermore, the presented qualitative and colorimetric parameters of the prints enabled the assessment of the applicability of used papers as printing substrates for ecologically favorable packaging.

The line width (often synonymously used for critical dimension, CD) is a crucial parameter in integrated circuits. To accurately control CD values in manufacturing, a reasonable CD reference material is required to calibrate the corresponding instruments. We develop a new reference material with nominal CDs of 160 nm, 80 nm, and 40 nm. The line features are investigated based on the metrological scanning electron microscope which is developed by the National Institute of Metrology (NIM) in China. Also, we propose a new characterization method for the precise measurement of CD values. After filtering and leveling the intensity profiles, the line features are characterized by the combination model of the Gaussian and Lorentz functions. The left and right edges of CD are automatically extracted with the profile decomposition and k -means algorithm. Then the width of the two edges at the half intensity position is regarded as the standard CD value. Finally, the measurement results are evaluated in terms of the sample, instrument, algorithm, and repeatability. The experiments indicate efficiency of the proposed method which can be easily applied in practice to accurately characterize CDs. [ABSTRACT FROM AUTHOR]

The 13C and 19F NMR spectra of the original and irradiated polytetrafluoroethylene samples were studied in the range of gamma radiation doses of up to 50 kGy. In this range, the 19F NMR spectrum width increases linearly with an increase in the absorbed dose. It is concluded that it is possible to monitor technological doses by the NMR method using polytetrafluoroethylene as a detector. [ABSTRACT FROM AUTHOR]

Kierlik et al. recently reported their study in this journal on the application of Mössbauer spectroscopy in identifying the iron-containing components in Upper Silesian topsoil as being under industrial anthropopressure. While the presented work is an excellent example of characterizing topsoil, a significant part of the study involving iron-bearing samples using 57Fe Mössbauer spectroscopy is erroneous. In the spectral fitting routine for the obtained Mössbauer spectra of the sample IIA (Figure 2; Table 3), the authors have erroneously fitted only a single sextet for magnetite, which is unacceptable. The line width obtained by them is also incorrectly mentioned in Figure 2, as evident from fitting D1 and D2 doublets as well as of magnetite tetrahedral and octahedral sites, making the relative abundances of individual phases meaningless. The inaccurate line width makes the authors fit the inadequate number of doublets necessary for the iron-bearing phases present in these samples, resulting in incorrect relative abundance for the other phases found in the materials, making the subsequent discussion not much useful.

In this letter, we present a numerical approach to obtain the ferromagnetic resonance spectra of micrometer- and nanometer-sized magnetic elements by micromagnetic simulations. By mimicking common experimental conditions, we applied a static magnetic field and used a linearly polarized oscillating magnetic field to excite magnetization dynamics. A continuous single-frequency excitation is utilized, which permits the study of the steady-state dynamics in the space and time domain. This gives direct access to resonance fields, linewidths, and relative amplitudes as observed in the experiments, which is not easily accessible in pulsed schemes and allows for a one-to-one identification between simulation and experiment. Similar to numerical approaches using pulsed excitations, the phases, ellipticity, and spatial mode profiles of the spin-wave excitations may also be accessed. Using large excitation powers, we then showcase that one can additionally study nonlinear responses by this method, such as the nonlinear shift of the resonance fields and the foldover of the absorption lines. Since the dynamic susceptibility is directly determined from standard outputs of common micromagnetic codes, the presented method is robust, efficient, and easy-to-use, adding to its practical importance.

Metal halide perovskite nanocrystals are under intense investigation for their outstanding optical and electronic properties. The presence of higher fine structure states, let alone nonequilibrium processes within the fine structure, and multiexcitonic fine structure remains poorly understood due to a lack of experimental probes. Here, we use time-resolved photoluminescence (t-PL) spectroscopy with an improvement from 100 to 3 ps resolution which reveals previously unobserved spectral dynamics from excitons to multiexcitons in 15 nm CsPbBr 3 nanocrystals. The simple and immediate observation from temperature dependence is a previously unobserved fine structure to the multiexcitons. Further insight is gleaned from t-PL spectral bandwidth trajectories at extrema in temperature and exciton density. The bandwidth trajectories reveal the presence of a previously unobserved fine structure in excitons as well as multiexcitons. The bandwidth trajectories reveal a complex history, from multiexciton recombination to exciton thermalization to Auger heating to lattice thermalization. Whereas the amplitude of these spectral effects is large, ∼60 meV, modeling suggests that the spectral effects are mostly phonon based illustrating the importance of the lattice on light emission from metal halide perovskite nanocrystals.

Abstract At consideration of the spin dynamics of nuclei in liquids or gases the dipole-dipole interaction Hamiltonian is divided into an intramolecular interaction part describing the interaction between spins inside a molecule and the part related to the intermolecular interaction of spins of different molecules. For liquid entrapped in nanopores it is shown that due to restricted motion of molecules the intramolecular interactions are not averaged to zero and contribute in NMR signals for nanopores with the characteristic size of the order of the molecule hydrodynamic radius. The intermolecular interactions are essential for the pore characteristic size up to hundreds nm. It is shown that the transverse relaxation time, line width, and intensity of NMR signal for cylindrical and ellipsoidal pores should possess the same angular dependence and differ by form-factors for nanopores. Their dependences on the pore volume and form are analyzed. Although nanopores contain large number of spins, ~106, the line width is estimated as 300 Hz, that significantly differs from one for bulk water (~1 Hz). Assuming the Gaussian distribution of nanopore orientations, we calculated the anisotropy of the transverse relaxation rate for a collagen fiber sample possessing three histological zones with different degrees of fibers ordering. Good agreement with the published experimental data is obtained by adjustment of few parameters - the standard deviation, averaged fiber direction, and weight factors which characterize the ordering of fibrils, their orientations in each zone, and the relative dimensions of these zones. Highlights • The dipolar intra- and inter-molecular interactions are considered. • The intramolecular interactions are averaged to zero for cavities with size ≥0.2 nm. • The intermolecular interactions are essential for the cavities with size <400 nm. • We calculated the anisotropy of the transverse relaxation. • The comparison of the data and calculation shows a good agreement.

Graphical abstract Abstract We propose a new integrated demultiplexer model using the two-dimensional photonic crystal (2D PC) through the hexagonal resonant cavity (HRC) for the International Telecommunication Union (ITU) standard. The integrated model of demultiplexer for both 25 GHz and 50 GHz has been designed for the first time. The demultiplexer consists of bus input waveguide, drop waveguide, Hexagonal Resonant Cavity (HRC), 6 Air Hole Filter (6-AHF), 7 Air Hole Filter (7-AHF). The 7-AHF is used to filter 25GHz wavelength, and the 6-AHF filter is used to filter 50 GHz wavelength. The Q-factor on the designed demultiplexer is flexible based on the idea of increasing the number of air holes between drop waveguide and resonant cavity. The demultiplexer is designed to drop maximum 8 resonant wavelengths. One side of demultiplexer is able to drop 50 GHz ITU standard wavelengths, which are of 1556.3 nm, 1556.7 nm, 1557.1 nm and 1557.5 nm, and further the other facet is able to drop 25 GHz wavelengths, which are of 1551.4 nm, 1551.6 nm, 1551.8 nm, and 1552.0 nm. The proposed demultiplexer may be carried out within the integrated dual system. This system is able to lessen the architecture cost and the size is miniaturized substantially.

The static magnetic susceptibility of the rf coil can substantially distort the field B 0 and be a dominant source of line broadening. A scaling argument shows that this may be a particular problem in microcoil NMR. We propose coil extensions to reduce the distortion. The actual rf coil is extended to a much longer overall length by abutted coil segments that do not carry rf current. The result is a long and nearly uniform sheath of copper wire, in terms of the static susceptibility. The line shape improvement is demonstrated at 43.9 MHz and in simulation calculations.

Low‐frequency electron spin resonance studies were performed for 2 mM concentration of deuterated permeable and impermeable nitroxyl spin probes, 3‐methoxycarbonyl‐2,2,5,5‐tetramethyl‐pyrrolidine‐1‐oxyl and 3‐carboxy‐2,2,5,5,‐tetramethyl‐1‐pyrrolidinyloxy in pure water and various concentrations of corn oil solution. The electron spin resonance parameters such as the line width, hyperfine coupling constant, g factor, rotational correlation time, permeability, and partition parameter were estimated. The broadening of line width was observed for nitroxyl radicals in corn oil mixture. The rotational correlation time increases with increasing concentration of corn oil, which indicates the less mobile nature of spin probe in corn oil mixture. The membrane permeability and partition parameter values were estimated as a function of corn oil concentration, which reveals that the nitroxyl radicals permeate equally into the aqueous phase and oil phase at the corn oil concentration of 50%. The electron spin resonance spectra demonstrate the permeable and impermeable nature of nitroxyl spin probes. From these results, the corn oil concentration was optimized as 50% for phantom studies. In this work, the corn oil and pure water mixture phantom models with various viscosities correspond to plasma membrane, and whole blood membrane with different hematocrit levels was studied for monitoring the biological characteristics and their interactions with permeable nitroxyl spin probe. These results will be useful for the development of electron spin resonance and Overhauser‐enhanced magnetic resonance imaging modalities in biomedical applications. [ABSTRACT FROM AUTHOR]

The laser-activated spectra of nanocrystalline Y 2 O 3 :Er 3+ recorded at various temperatures and two excitation energies are described and analysed herein. Based on recently published modified values of the C 2 -type Stark splitting of Er 3+ in the cubic Y 2 O 3 lattice, the Er 3+ multiplets in the observed spectra have been re-assigned. The upconversion routes of three 2 H 11/2 → 4 I 15/2 hot bands from 4 S 3/2 Kramers doublets have been traced, based on an Arrhenius-type analysis of these hot bands. We observed 5 peaks in the 2 H 11/2 → 4 I 15/2 hot band region with a different temperature behaviour. These bands belong to the 2 P 3/2 → 4 I 9/2 multiplet and their deviating temperature behaviour has been explained in terms of a cross relaxation mechanism. From the ratio between the laser-activated spectra that were recorded at different excitation energies we concluded that the two-photon absorption process becomes more efficient upon increasing the excitation energy. We have also put forward an explanation for the gradual broadening of the fluorescence bands of the 2 H 11/2 → 4 I 15/2 multiplet in going from 518 nm to 542 nm. The higher Stark splitting levels are due to a stronger electrostatic field of the host lattice and experience therefore a higher electron-phonon interaction, which explains the observed increase of FWHM at larger wavelengths.

Semiconducting transition metal dichalcogenide (TMDC) monolayers have exceptional physical properties. They show bright photoluminescence due to their unique band structure and absorb more than 10% of the light at their excitonic resonances despite their atomic thickness. At room temperature, the width of the exciton transitions is governed by the exciton–phonon interaction leading to strongly asymmetric line shapes. TMDC monolayers are also extremely flexible, sustaining mechanical strain of about 10% without breaking. The excitonic properties strongly depend on strain. For example, exciton energies of TMDC monolayers significantly redshift under uniaxial tensile strain. Here, we demonstrate that the width and the asymmetric line shape of excitonic resonances in TMDC monolayers can be controlled with applied strain. We measure photoluminescence and absorption spectra of the A exciton in monolayer MoSe2, WSe2, WS2, and MoS2 under uniaxial tensile strain. We find that the A exciton substantially narrows and becomes more symmetric for the selenium-based monolayer materials, while no change is observed for atomically thin WS2. For MoS2 monolayers, the line width increases. These effects are due to a modified exciton–phonon coupling at increasing strain levels because of changes in the electronic band structure of the respective monolayer materials. This interpretation based on steady-state experiments is corroborated by time-resolved photoluminescence measurements. Our results demonstrate that moderate strain values on the order of only 1% are already sufficient to globally tune the exciton–phonon interaction in TMDC monolayers and hold the promise for controlling the coupling on the nanoscale.
