Background: A stemless plastic scintillation detector (SPSD) is composed of an organic plastic scintillator coupled to an organic photodiode. Previous research has shown that SPSDs are ideally suited to challenging dosimetry measurements such as output factors and profiles in small fields. Lacking from the current literature is a systematic effort to optimize the performance of the photodiode component of the detector.

A sustainable biosorbent, silver nanoparticles-decorated coffee-ground waste (CWAg), was synthesized through a simple in-situ reduction method. CWAg is extensively characterized via SEM-EDX, PZC, FTIR, XRD, HR-TEM, and XPS analyses. The biosorbent was tested to remove chromium (Cr(VI)) and methylene blue (MB) from wastewater, and its antibacterial properties was evaluated.

Silver nanoparticles (AgNPs) have attracted significant interest in recent years owing to their unique physicochemical properties, including antimicrobial reduction capabilities, photocatalytic activity, self-cleaning features, superhydrophobicity, and electrical conductivity. Their characteristics render them highly advantageous for various textile, electronics, food and agriculture, water treatment, and biomedical applications. This detailed analysis explores the recent benefits and drawbacks of various synthesis methods, immobilization techniques, and characterization of AgNPs while emphasizing novel strategies that improve their functionality across different substrates.

The focus of this research is to examine the safe-haven properties of seven ethical and conventional asset classes using two sophisticated techniques: quantile coherence and Wavelet coherence. We analyze data ranging from October 3, 2011, to September 30, 2021, that encapsulates several global risk events. The results exhibit either positive or neutral associations between most assets and the Geopolitical Risk (GPR), indicating their safe haven capabilities against the GPR shocks.

This study investigated the impact of aspect ratio and crystal size distribution on the mother liquor content and drying rate of l-glutamic acid (LGA). LGA cooling crystallization was performed using two methods: spontaneous nucleation and seeding. First, to identify various crystalline forms of LGA and obtain α-form seeds, cooling crystallization was carried out through spontaneous nucleation and seeding.
