In the current era of perceptual consumption, it is difficult for commodities with popular design to meet the needs of consumers’ diversification and popular trends. Therefore, design personnel should consider how to meet needs and preferences of consumers at the stage of commodity design and business planning. With the development of science and technology, and diversified leather decorative texture types, appearance evaluation has become one of the factors affecting the perceptual characteristics of consumer decision-making to meet preferences of individual consumers. This research adopts qualitative research methods, conducts in-depth interviews with experts highly involved in leather technology expression techniques, works out attractiveness factors of leather technology technique expression, makes the evaluation grid diagram and analyze it to provide a reference basis for subsequent leather texture design.

This study aims to develop a green method to load silver nanoparticles (AgNPs) into the diatomite (D) pores to produce AgNPs-D composite material. The AgNPs were synthesized by pineapple leaf extract at the temperature of 70 °C for 30 min. The composite formation was characterized by UV-Vis, FTIR, TGA, particle sizes analysis, gravimetric, and color observation. The appearance of surface plasmon bands in 440–460 nm confirms the AgNPs formation. The percentage of the AgNO3 which converted to AgNPs was 99.8%. The smallest particle size of AgNPs was 30 nm, obtained in an AgNO3 concentration of 1 mM with a stirring time of 24 h at 70 °C. The colloidal AgNPs were stable for up to 7 days. The adsorption process of AgNPs was marked by the appearance of –C=O and –C–O– groups peak at 1740 and 1366 cm–1 on the FTIR spectrum. By adsorption and gravimetric technique, as much as 1 wt.% of AgNPs were loaded into D pores. The color of diatomite material changes from white to reddish-brown. The TGA analysis showed that the remaining D and AgNPs-D at 580 °C are 98.22% and 95.74%, respectively. The AgNPs loading through the green technology technique was expected to increase diatomite application in the biomedical field.

Titanium and its alloys are getting great attention in both medical and dental fields because of; excellent biocompatibility; light weight; excellent balance of mechanical properties; excellent corrosion resistance. The goal of this work is to study how the Co addition to Ti influences on the corrosion behavior of dental alloys. The Preparation of samples was accomplished by using powder technology technique. In which the raw materials used was pure titanium powder and pure cobalt powder. Characterization of sample includes (X-ray diffraction patterns, microstructure observations (scanning electron and optical microscopic), porosity percentage and corrosion test. Sample without cobalt addition was refer to an alloy with single a phase, while After the additions of cobalt in different percentage (5%, 10%,15%) α-Ti and intermetallic compound Ti2Co was observed from XRD and microstructure observations, the amount of Ti2Co phase slightly increase with increasing cobalt content. The porosity percentage decreases with increase in cobalt percentage. The corrosion rate decreases with increase in Co percentage.

In the present study, an effort was made to develop a novel dosage form by using a chrono-pharmaceutical approach for the treatment of hypertension using Diltiazem hydrochloride as a model drug. A time delayed capsule was prepared by sealing the pellets inside the insoluble hard gelatin capsule body with erodible hydrogel plug. The pellets were prepared by emulsion Fluidized Bed Wurster (bottom spray) technology technique. Optimized pellets formulations were selected based on dissolution studies. The entire device was enteric coated, so that the variability in gastric emptying time can be overcome and a colon-specific release can be achieved. Hydrogel plug (HPMCK4 and lactose in 1: 1 ratio) having 4.5kg/cm2 hardness and 100 mg weight was placed in the capsule opening and found that it was suitable to avoid the drug release in small intestinal fluid and to eject out the plug in colonic fluid and releasing the pellets into colonic fluid after a lag time criterion of 5 hours. In order to simulate the pH changes along the GI tract, three dissolution media with pH 1.2, 7.4 and 6.8 were successively used. FTIR study confirmed that there was no interaction between drug and polymer. Among all the formulations Diltiazem hydrochloride pellets coated with Eudragit FS 30D in 35% w/w concentrations shown prolonged release for a period of 12 hours. The obtained results revealed the capability of the system in delaying drug release for a programmable period of time and can prevent a sharp increase in the incidence of blood pressure, during the early morning hours, a time when the risk of hypertension attacks is the maximum.

The purpose of this community service is to increase sales turnover and expand the thread filter technology technique. The method of implementing the service activities in this program aims to improve the welfare of the people who work as salt farmers who previously processed salt using traditional techniques. Therefore, this service activity desires to develop and apply the latest technology, namely Thread Filter and/or Geomembrane (plastic), to provide solutions to salt farmers in developing their business in an easier and more modern way which increases the quantity and quality of the salt produced. Besides, through this service salt farmers are also trained on how to process salt into nanoparticles, as a good product for skin care. Thus, the salt production process will be easier and faster and the benefits obtained by salt farmers will be higher. In this service activity, it will focus on traditional salt farmers to be able to switch and apply the technology of thread filter (TUF) or Geomembrane (plastic) as a process of making salt easily and competently for the community. The results showed that using Thread Filter Technology (TUF) was able to produce results of four to five tons after using geomembrane. Previously without using TUF farmers from the village were only able to produce three tons of salt. The prospect of salt farm business is profitable when applied the techniques of TUF or geomembrane. Finally, the salt farmers can earn income significantly.

This paper highlights domestic consumption of electricity in UK and effect of electric vehicles on the domestic demands. Also, consider the trends and growth of domestic electricity demand and the implication of using the electric vehicles. One challenging factor is the management of the domestic load electricity demand on the electric vehicles. To this end, this paper investigates new management technology technique that can be used in domestic sector. The key point to tackle this problem is to outline pattern shape of the electricity usage per individual household. However, lack of information on individual usage per consumer is complicating the path to the new solutions. Data were collected from daily energy consumption and energy peak demands from UK electricity industries. In additional the research explores the effect of recently introduced UK energy plan to reduce the CO2 emission and how this affects usage of the electric vehicle. The proposal in the new solutions includes the use of renewable energy sources such as solar panels and batteries banks for domestic supply. This would go a long way to reducing electricity demand as well as reduce CO2 emission from domestic sector.

The economic and technical breakthroughs in solid oxide fuel cell (SOFC) for commercial success still depend on high-quality manufacture, reliability, efficiency, and must have an acceptable cost when compared to competing technologies. The application of flame-based technologies as a one-step deposition technique for SOFC component manufacture has potential to reduce both cost and production time. In this article, cells produced by flame processes have been reviewed with emphases placed on the Reactive Spray Deposition Technology technique. Various experimental methods and examples for the synthesis of porous electrodes and dense electrolytes are reviewed. The studies focus on determining the range of the flame conditions under which each of the individual cell components for low temperature SOFC applications ∼600 °C could be successfully deposited. © 2011 ASM International.

In this study, piezoelectric inkjet technology was used for microscale patterning of a two-component medical hydrogel (sold under the registered trademark Coseal®). A MEMS-based piezoelectric actuator was used to control the flow of polyethylene glycol in a sodium phosphate/sodium carbonate solution through inkjet nozzles. A hydrogen chloride solution was subsequently used to cross-link the polyethylene glycol material. Optical microscopy, scanning electron microscopy, atomic force microscopy, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, and nanoindentation studies were performed to examine the structural, chemical, and mechanical properties of the inkjetted hydrogel material. Scanning electron micrographs revealed that the inkjetted material exhibited randomly oriented cross-linked networks. Fourier transform infrared spectroscopy revealed that the piezoelectric inkjet technology technique did not alter chemical bonding in the material. Piezoelectric inkjet printing of medic...

Approximately 500 post baccalaureate students were surveyed about 11 pedagogical techniques to which they were exposed in a media-friendly lecture hall. The data allowed for students to be grouped into “non-likers” (those who showed an absence of positive responses to a particular method) and “likers” (those who indicated they liked the method). Web-oriented methods showed “non-liking” rates ranging from 28–42%. Ironically, while brief stories (using speech, PowerPoint text and animation) generated the least amount of “non-liking,” an audio story by a classic storyteller generated the most “non-liking.” A psychodynamic model was constructed incorporating information-intake styles, information-expression styles, and demographics to examine the determinants of such “liking”/“non-liking” via Logistic Regression analyses. The model was reliable for six of the 11 variables, and numerous predictor variables revealed the complex interplay between pedagogical technique and the type of student. Even with popular techniques like sound-bites, PowerPoint, animation, MPEG, stories, and the use of the Internet, there was a substantial rate of “non-liking.”

A rapid liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed and optimized for the simultaneous determination of bisphenol A, 4-t-octylphenol and 4-nonylphenol in human blood serum. For the first time, the electrospray ionization (ESI) parameters of probe position, voltage potential, sheath gas flow rate, auxiliary gas flow rate, and ion transfer tube temperature were thoroughly studied and optimized for each phenol by a univariate approach. As a consequence, low instrumental limits of detection were reported, demonstrating at 0.2 ng/mL (in solvent matrix) excellent injection repeatability (RSD

The authors presents a series of eight patients and discuss current concepts of dealing with this common and distressing surgical complication.

Over the past century, synthetic adhesives have largely displaced their natural counterparts in medical applications. However, rising concerns over the environmental and toxicological effects of the solvents, monomers, and additives used in synthetic adhesives have recently led the scientific community to seek natural substitutes. Marine mussel adhesive protein is a formaldehyde-free natural adhesive that demonstrates excellent adhesion to several classes of materials, including glasses, metals, metal oxides, and polymers. In this study, we have demonstrated computer aided design (CAD) patterning of various biological adhesives using piezoelectric inkjet technology. A MEMS-based piezoelectric actuator was used to control the flow of the mussel adhesive protein solution through the ink jet nozzles. Fourier transform infrared spectroscopy (FTIR), microscopy, and adhesion studies were performed to examine the chemical, structural, and functional properties of these patterns, respectively. FTIR revealed the piezoelectric inkjet technology technique to be nondestructive. Atomic force microscopy was used to determine the extent of chelation caused by Fe(III). The adhesive strength in these materials was correlated with the extent of chelation by Fe(III). Piezoelectric inkjet printing of naturally-derived biological adhesives may overcome several problems associated with conventional tissue bonding materials. This technique may significantly improve wound repair in next generation eye repair, fracture fixation, wound closure, and drug delivery devices.

Composites of carbon nanotubes (CNT) in polymeric matrices have attracted considerable attention in the research communities due to their good electrical conductivity, high stiffness and high strength at relatively low CNT contents. Effective utilization of CNT in composites depends primarily on the ability to disperse them homogeneously throughout the polymer matrix, avoiding the formation of bundles due to van der Waals interactions existing between the nanotubes. In this work composites of polystyrene at various percentages of SWNT were fabricated using Latex Technology technique, a polymer type-independent method based on using a surfactant as a dispersing agent. An electrical characterization of SWNT composites was performed both in DC and AC modes. From the analysis of DC data a percolative behavior was found for the conductivity as function of SWNT content. The innovative contribution of this work consists in the modeling of the composite material upon its electrical properties. AC measurements and the analysis of impedance as function of angular frequency lead to the formulation of an equivalent circuit able to model the composite material in correspondence of the percolative threshold.

At a conference on technological change, I get a little unsettled to talk about technology in isolation of its use and application. It makes me think of Pentagon Press releases when they describe the capabilities of various missiles, tanks, and bombs without any acknowledgement of what it's like to be burned, maimed, or irradiated.1

The electrodes of most power sources are made by some powder technology technique. To improve the characteristics of accumulators, we must find relationships between the characteristics of the powdered electrode materials and the electrochemical parameters of the accumulator. We have examined the connection between the features of powdered graphite and its applicability to power sources. A plastic bonded, Ni/Cd accumulator, positive electrode was chosen as amodel. We chose oxidation by heat treatment as a means of characterizing the electrochemical behaviour of the graphites. The features of powdered graphite, and the connection between the powder characteristics and the electrochemical behaviour of the final cell, may be characterized mathematically. Physical tests and electrochemical measurements show that a graphite possessing an average oxidizability is the best material to use. If the graphite oxidizes easily it is reduced readily electrochemically. A graphite which is hard to oxidize, however, is usually very coarse and utilisation of the active material reduces exponentially with its addition.

The radiation technique is a useful technology technique to induce suitable modifications of the polymeric materials. In the present work, poly allyl diglycol carbonate (CR-39) solid state nuclear track detector samples were irradiated using different doses (150–950 kGy) of gamma ray irradiations. The effect of gamma ray irradiations on the optical and electrical, properties of CR-39 was investigated. The obtained results showed a decrease in the optical energy gap with increasing the gamma dose. Increase in the numbers of carbon atoms (N) in a formed cluster with increasing the irradiation dose was observed. Meanwhile, an increase in the Ac conductivity was obtained with increasing the gamma dose. Also, the variation in the dielectric constant and loss with irradiation dose was studied at the room temperature. The results indicate that the gamma ray irradiations in the dose range 150–950 kGy enhance the optical and electrical properties of the CR-39 polymer samples.
