Enhancing Open‐Circuit Voltage and Fill Factor in Sn‐Based Perovskite Solar Cells: Challenges and Opportunities for Sustainable Photovoltaics

open access: yesSusMat, Volume 5, Issue 6, December 2025.
This review summarizes advances in tin (Sn)‐based perovskite solar cells, a promising lead‐free alternative. It examines the main causes of Voc and fill factor losses, including Sn2+ oxidation, undercoordinated sites, and deep‐level traps. Strategies such as molecular coordination, surface passivation, compositional tuning, interface engineering, and ...

Metabolic Effects of Oral Phenelzine Treatment on High-Sucrose-Drinking Mice [PDF]

open access: yes, 2018
Phenelzine has been suggested to have an antiobesity effect by inhibiting de novo lipogenesis, which led us to investigate the metabolic effects of oral chronic phenelzine treatment in high-sucrose-drinking mice.

Hypothalamic Astrocytes Exhibit Glycolytic Features Making Them Prone for Glucose Sensing

open access: yesGlia, Volume 73, Issue 11, Page 2253-2272, November 2025.
Main Points Hypothalamic astrocytes versus cortical astrocytes: are more glycolytic due to high Pkm2, Glut1 and Mct4 expression do not exhibit glutamate‐induced glycolysis detect glucose concentration variations via an AMPK sensor with altered lactate production.

Development of biomimetic enzyme-linked immunosorbent assay based on molecular imprinting technique for semicarbazide detection

open access: yesFood and Agricultural Immunology, 2020
Herein, we present a direct competitive biomimetic enzyme-linked immunosorbent assay (BELISA) method for the determination of semicarbazide (SEM) using a molecularly imprinted polymer (MIP) film as the bionic antibody. The best monomer (methacrylic acid)

Some semicarbazide derivatives and their antimicrobial activity

open access: yesCommunications, Faculty Of Science, University of Ankara Series B Chemistry and Chemical Engineering, 1993
Various semicarbazides and thiosemicarbazides (1-5) and their cyclised products, triazoles, oxadiazoles and thiadiazoles (6-9) have been reported to possess antibacterial, antitubercular and antifungal activities. Based on these findings it w as of interest to prepare some new arylsemicarbazide and arylthiosemicarbazide derivatives and to evaluate ...

Batch Synthesis of Primaquine Diphosphate Anti‐Malarial Drug

open access: yesChemistry – A European Journal, Volume 31, Issue 59, October 22, 2025.
According to the WHO, a child under the age of five dies every 2 minutes from malaria in Africa. It is therefore paramount that access and availability of anti‐malarial drugs must be improved. We report a process for the synthesis of Primaquine Diphosphate, where key intermediates were obtained in a much shorter reaction time compared to processes ...

Potential role of NADPH-oxidase in early steps of lead-induced oxidative burst in Vicia faba roots [PDF]

open access: yes, 2008
The mechanism of oxidative burst induced by lead in Vicia faba excised roots was investigated by luminol-dependent chemiluminescence. Results showed that lead triggered a rapid and dose-dependent increase in chemiluminescence production.
