ABSTRACT Over the past two decades, the frequency of natural hazard incidents has steadily risen, leading to substantial human casualties, infrastructure destruction, societal and economic disruption. The occurrence of disasters, both of natural and human origin, has exhibited an upward trend in frequency over the past few decades on a global scale, posing a significant threat to diverse populations. Over time, remote sensing technologies have proven to be effective in analysing and monitoring diverse natural disasters, including but not limited to droughts, earthquakes, tsunamis, landslides and cyclones. The significant extent of its coverage capacity and the ability to repeat observations make its application economically efficient. This paper aims to elucidate the fundamental contributions and role of remote sensing in disaster management applications. In a comprehensive analysis, this study explores recent practical applications in the context of disaster events. The utilisation of diverse methodologies and functions of remote sensing in disaster monitoring and control is further expanded to encompass the domain of disaster risk management, employing cutting‐edge sensors and satellites from emerging technological advancements. This paper also addresses challenges related to disaster monitoring, detection and management. Emergencies, particularly during typical catastrophe scenarios, often witness partial disruptions in communication networks. Consequently, the role of alternative networks becomes paramount in enabling effective disaster detection and management strategies. Emerging issues are highlighted, and potential directions for future research are outlined and also support sustainable development goal 13 (climate action). [ABSTRACT FROM AUTHOR]

A series of K2Mg2(MoO4)3 (KMM) phosphors doped with Dy3+ ions was synthesized by the solid-state reaction (SSR) method. The crystal structure, morphological behaviour, and photoluminescence (PL) properties were investigated through instrumentation techniques like X-ray diffraction (XRD), scanning electron microscopy (SEM), and spectrofluorophotometer. The KMM material is a member of the P212121 space group and has an orthorhombic structure. FTIR (Fourier transform infrared) measurements were used to identify functional groups inside the host lattice. The optical bandgap was computed from the diffuse reflectance spectrum (DRS) data. The synthesized phosphor material exhibits a 4f transition of Dy3+ ions, excited by 387 nm, and the most intense emission peak was observed at 576 nm. Double exponential behavior was seen in the PL decay spectral profiles taken under excitation wavelength of 387 nm. The CIE coordinates of the prepared phosphor lie in yellowish white region. We wish to propose Dy3+ ions doped KMM phosphor as a viable solution for applications in white light emitting diodes (w-LEDs). [ABSTRACT FROM AUTHOR]

Borosilicate glasses were prepared via melt quench technique with different concentration of Nd3+ ions. X-ray diffraction (XRD) was performed for the prepared glass to study the amorphous structure. The glass stability was studied by Thermo-gravimetric Analysis (TGA). Spectroscopic analysis of the prepared glasses was done through absorption, excitation, emission and decay measurements. Absorption spectra was used to evaluate the J-O parameters. Radiative parameters are evaluated with the help of application of J-O theory. Emission spectra show three prominent bands in NIR region arising from 4F3/2 → 4I9/2, 4I11/2 and 4I13/2 centered around 910, 1068 and 1339 nm accordingly, with the most intense being the one at 1068 nm. Stimulated emission cross section, branching ratio and quantum efficiency for 4F3/2 → 4I11/2 transition is very high and is suitable for lasing applications. Dipole–dipole interaction is observed among activator ions on the basis of Dexter theory. The optimized Nd3+ doped glass (NBS10) possess maximum value for all radiative parameters and hence can be best suited for applications in the area of lasers and fiber amplifiers.

A series of Er3+ ions doped Sr9Y2W4O24 (SYW) phosphors have been synthesised using solid‐state reaction technique. For optical thermometry and solid state lighting applications, the crystal structure, morphological, and luminescence features of the SYW : Er3+ phosphors were explored. X‐ray diffraction (XRD) reveal that synthesized phosphors having single phase with a tetragonal crystal structure and I41/a space group. Scanning electron microscopy (SEM) was used to examine the morphological behaviour and presence of composition elements. The optical bandgap of the phosphor was evaluated using UV‐Vis diffuse reflection spectra (DRS). The photoluminescence (PL) emission spectra were captured under 380 nm excitation, and the peak with the maximum intensity was identified at 563 nm ascribed to transition 4S3/2→4I15/2, that emits green color in visible region. The temperature dependent PL (TD‐PL) spectra show that SYW phosphor is substantially more thermally stable, having thermal activation energy of about 0.247 eV. Additionally, the fluorescence intensity ratio (FIR) was used to study the optical sensing characteristics of the thermal quenching transitions (2H11/2, 4S3/2) with maximum relative sensitivity (SR) and an absolute sensitivity (SA) being 1.33 % K−1and 0.307 % K−1, respectively. All of the aforementioned findings demonstrate that SYW : Er3+ ions doped phosphors have potential for optical thermometry and other photonic devices. [ABSTRACT FROM AUTHOR]

The current study focuses on the synthesis and other detailed studies on CaBi2Nb2O9 (abbreviated CBNO) phosphor doped with Dy3+ ions. The aforementioned phosphors were prepared via a solid-state reaction procedure and a comprehensive analysis of the crystal structure, particle morphology, vibrational bands, luminous characteristics, decay and thermal stability of the phosphors was done. Phase identification of the synthesized material was carried out using X-ray diffraction (XRD) technique and the optical bandgap was determined using diffuse reflectance spectra (DRS). The morphological studies and particle size estimation of the phosphor material were conducted using a scanning electron microscope (SEM). Under 452 nm excitation, the photoluminescence (PL) spectra of Dy3+-doped CBNO phosphor exhibit three peaks at 482, 576, and 666 nm, which correspond to the transitions 4F9/2 → 6H15/2, 6H13/2, and 6H11/2. The electric dipole–dipole interaction was the main mechanism for concentration quenching for Dy3+ ions. The estimated CIE chromaticity coordinates for Dy3+ ion-doped CBNO phosphors fall in the white region. The temperature-dependent PL (TD-PL) findings reveals that CBNO phosphors have a considerably superior thermal stability. The results of these investigations suggest that the CBNO phosphors doped with Dy3+ ions exhibit promising properties that could be used for prospective w-LEDs and other optoelectronic device applications.

Captivating taglines in an advertisement and attractive packaging have a huge impact on consumption behaviour especially among Gen Z and Gen Alpha. However, studies reveal that many buyers fail to explore the minute details of product components concealed behind these appealing taglines. This results in conflict between the attractiveness of ads and the harm the product may cause to consumer's health, which is evident when people choose beauty products over their own health or non-healthy food and beverages (F & B). The estimates in 2019 showed that 77 million individuals had diabetics in India, which is expected to rise to over 134 million by 2045. Even after this, 57% of these individuals remain undiagnosed. At the same time, skin cancer rates are increasing globally. This study was carried out with the primary goal of exploring the complexities of consumer choices within the context of F & B and Cosmetics products. The study investigates the practice of transparency, consumer protection, social responsibility, and ethical advertising associated with responsible marketing. For this, a total of 17 products, out of which nine products were from F & B and eight products from the cosmetics category, were bought. A detailed investigation is done to understand the ingredients mentioned in the packaging and then compare them with the taglines used by the brands under these product categories for positioning and making promises to consumers. This detailed assessment of the components of F & B within these categories reveals a disturbing pattern of misleading advertisements. A crucial contributing factor seems to be consumers' clear lack of understanding, leading to choices that may not be in their best interests. The study findings provide perspectives that will allow marketers to successfully contribute to long-term sustainable development goals, eventually prioritizing consumer quality of life. This study also underlines the significance of linking corporate strategies with ethical concerns, opening the way for a more responsible marketing paradigm that protects the interests of both businesses and consumers while promoting long-term societal well-being.

Traditional freshwater sources have been over-abstracted in the worldwide crisis of water scarcity. Effluents have extremely high amounts of Zn2+ and Pb2+, according to an investigation of wastewater samples taken from several industrial zones. However, these heavy metals are among the most harmful to both humans and wildlife that are currently known. Streptomyces sp. is utilized in this study as a biosorbent to biosorb Zn2+ and Pb2+ from single and binary aqueous solutions. Several factors, such as biomass concentration (0.25–4 g), metal solution concentration (5–50 mg L−1), solution pH (2–5), and contact time were standardized. Streptomyces sp. biomass was able to extract 93% Pb2+ and 91% Zn2+ from a single and 95% Pb2+ and 97% Zn2+ from a binary metal aqueous solution containing 25 mg L−1 and pH 4. The highest adsorption capacity in both single and binary sorption experiments was determined to be shared by Zn2+ and Pb2+. The biosorbent's metal adsorption increased from 0.48 to 4.56 mg g−1 for Pb2+ and from 0.21 mg g−1 to 4.65 mg g−1 for Zn2+ when the metals were present singly, and from 0.44 to 4.18 mg g−1 for Pb2+ and from 0.41 mg g−1 to 5.67 mg g−1 for Zn2+ when the metals were present in binary form. The amount of metal ions was raised from 5 to 50 mg L−1. Correlation coefficient (R2) values indicate that the adsorption pattern for Zn2+ and Pb2+ followed Freundlich isotherm R2 > 0.9543 for single and 0.9582 for binary sorption system. In order to remove Zn2+ and Pb2+ from an aqueous solution, Streptomyces sp. is a potential and different source of adsorbents. [ABSTRACT FROM AUTHOR]

In this present work, Dysprosium (Dy3+) ions doped potassium zinc strontium borate (KZSB) glasses were synthesized via the melt-quench method. X-ray diffraction (XRD) study of the prepared glasses shows a broad hump and confirms the amorphous nature of the glasses. Various vibrational shoulders were seen in the Fourier transform infrared (FT-IR) spectrum. Thermo gravimetric analysis–differential scanning calorimetry (TGA–DSC) was carried out to check the thermal stability and corresponding weight loss behavior of the un-doped sample. Absorption spectra were recorded for un-doped as well as doped glasses in the UV–VIS–NIR region, and the corresponding optical band gap was calculated. The photoluminescence (PL) spectra of as-prepared Dy3+ doped KZSB glasses under 350 nm excitation show three peaks at 482, 575 and 665 nm corresponding to the transitions 4F9/2 → 6H15/2, 6H13/2 and 6H11/2. Commission Internationale de I'Eclairage (CIE) chromaticity coordinates calculated from the emission data lie in the white region. The photometric analysis of prepared glasses under UV lamp with 365 nm excitation also shows white emission. Temperature-dependent PL (TDPL) investigation demonstrates the superiority in thermal stability of the as-prepared glasses, with an activation energy of 0.232 eV estimated for 0.5 mol% (optimized concentration of rare earth ion) of Dy3+ ions. After analyzing the results of all studies, we propose to use these borate glasses doped with Dy3+ ions for white light-emitting diodes (w-LEDs) fabrication and other solid state lighting (SSL) applications.
