Optimizing Charge Transport Layers to Enhance the Performance of Lead-Free RbGeI Perovskite Solar Cells: A Comprehensive Analysis of ETL and HTL Engineering.

This study investigates innovative hybrid perovskite solar cells using rubidium-germanium-iodide (RbGeI) as the substrate, incorporating various hole transport layers like CuO, CuO, and SnSe, and wide-bandgap chalcogenide electron transport layers (ETLs) like IGZO, WS, InS, and ZnSe. After selecting IGZO as the optimal ETL, its depth was optimized using the SCAPS-1D simulator to evaluate device performance. Three device configurations were examined: device-I (Al/FTO/IGZO/RbGeI/CuO/Ni), device-II (Al/FTO/IGZO/RbGeI/CuO/Ni), and device-III (Al/FTO/IGZO/RbGeI/SnSe/Ni), with a detailed analysis of the doping concentration, thickness of the layer, density of defect, operational temperature, and interface defects.

Evaluation of a Low-Cost Amplifier With System Optimization in Thermoacoustic Tomography: Characterization and Imaging of Ex-Vivo and In-Vivo Samples.

Microwave-induced thermoacoustic tomography (TAT) is a hybrid imaging technique that combines microwave excitation with ultrasound detection to create detailed images of biological tissue. Most TAT systems require a costly amplification system (or a sophisticated high-power microwave source), which limits the wide adoption of this imaging modality. We have developed a rotating single-element thermoacoustic tomography (RTAT) system using a low-cost amplifier that has been optimized in terms of microwave signal pulse width and antenna placement.

Comparative energy demand and carbon footprint analysis of textile waste management systems in Australia.

In modern societies, especially in developed countries, textile waste management has become a critical issue due to overconsumption and throw-away culture. This case study aims to develop a comprehensive quantitative energy demand and carbon footprint analysis model using CCalC2 software to identify the most sustainable end-of-life management practices for the textile waste in Australia, the second-largest consumers of textile products. Results of this study showed that chemical recycling is the best option from the standpoint of saving pulp production energy and recycled pulp material, while it is a carbon-intensive process (6401 kg COeq/1000 kg).

Groundwater quality drivers in the drought-prone Thakurgaon District, Northwestern Bangladesh: An integrated fuzzy logic and statistical modeling approach.

Groundwater quality in the drought-prone Thakurgaon District, Northwestern Bangladesh, is deteriorating due to a combination of natural and anthropogenic factors. This study evaluates the key drivers of groundwater quality degradation by employing ecotoxicological risk indices, such as the Heavy Metal Pollution Index (HPI), Heavy Metal Evaluation Index (HEI), and Nemerow's Pollution Index (NPI). An innovative fuzzy logic approach is used to integrate these indices and reduce uncertainty, while Automatic Linear Modeling (ALM) predicts the primary impacts on the Fuzzy Groundwater Quality Index (FGWQI).

High-throughput screening of natural antiviral drug candidates against white spot syndrome virus targeting VP28 in Penaeus monodon: Computational drug design approaches.

The white spot syndrome virus (WSSV), considered the deadliest pathogen impacting Penaeid shrimp (Penaeus monodon), remains worrisome for the global shrimp industry due to its extreme virulence and mortality rate of up to 100%. To date, there has been no breakthrough in effective antivirals or vaccines that can mitigate the financial damage caused by the pathogen. The distinctive structure of VP28 facilitates its role as a trimer, serving as the primary envelope protein of WSSV.

LightViz: autonomous light-field sensing, mapping, and assessment for distributed light pollution monitoring.

Existing technologies for distributed light-field mapping and light pollution monitoring (LPM) rely on either remote satellite imagery or manual light surveying with single-point sensors such as SQMs (sky quality meters). These modalities offer low-resolution data that are not informative for dense light-field mapping, pollutant identification, or sustainable policy implementation. In this work, we propose LightViz-an interactive software interface to survey, simulate, and visualize light pollution maps in real time.

Implementing the 'Integrated Model for Supervision' for mental health and psychosocial support programming within humanitarian emergencies: A mixed-methods evaluation across six humanitarian contexts.

Method for isolation and quantification of inositol glycan produced by glycosylinositol phosphoceramide-hydrolyzing phospholipase D in plants.

Glycosylinositol phosphoceramide (GIPC) is the most abundant sphingolipids in plants. Previously, we found phospholipase D (PLD) activity that hydrolyzes GIPC to phytoceramide 1-phosphate (PCerP) in plants and revealed that GIPC-PLD activity is carried out by an enzyme encoded by non-specific phospholipase C3 (NPC3) gene. In this study, we established a method for isolation and quantification of inositol glycan (InoGly), a counterpart of PCerP produced from GIPC, using TLC imaging.
