Pressurized IrX (X = P and As) stands out as the sole -type superconductors among dozens of filled-skutterudites that are primarily characterized by -type charge carriers. The emergence of superconductivity is proposed to be intimately related to the inharmonic rattling phonons originating from the filled atoms. Here, we explore the impact of the size effect of the rattling atoms by substituting X with Sb, whose radius is 30 and 17% larger than those of P and As, respectively.

Mixing different metal ions at the B site of ABX perovskites offers a promising approach for addressing challenges related to toxicity, stability and performance in optoelectronic applications. One such example is CsPbSnBr which addresses the toxicity issue posed by lead while allowing us to tune optoelectronic properties such as the band gap. In this work, nearly monodisperse CsPbSnBr quantum dots (QDs) were synthesized with variable Pb/Sn compositions, CsPbBr, CsPbSnBr and CsPbSnBr.

Introduction: Several adverse drug reactions (ADRs) go unreported within a healthcare setting despite the risks they cause. We therefore decided to conduct this study in order to recognize the obstacles that hinder the healthcare professionals (HCPs) in a tertiary care hospital in Kattankulathur, Tamil Nadu from reporting ADRs and what strategies ought to be implemented.
Methods: We carried out a cross-sectional study among the HCPs such as doctors, pharmacists and nurses within our institution.

Background: Shake flasks are essential tools in biotechnological development due to their cost efficiency and ease of use. However, a significant challenge is the miniaturization of process analytical tools to maximize information output from each cultivation. This study aimed to develop a respiration activity online measurement system via off-gas analysis, named "Transfer rate Online Measurement" (TOM), for determining the oxygen transfer rate (OTR), carbon dioxide transfer rate (CTR), and the respiration quotient (RQ) in surface-aerated bioreactors, primarily targeting shake flasks.

Background: Obesity plays a crucial role in the development of metabolic disorders including diabetes, coronary and renal diseases. There are several factors involved in the pathology of obesity, including chronic inflammation and exposure to environmental contaminants. Recently, the cholinergic co-hydrolyzing enzyme BChE has been associated with clinical conditions such as diabetes and obesity.
