August 2025
This paper provides a detailed analysis of pure CsPbIBr and 4% Ce-doped CsPbIBr perovskite films, with an emphasis on their structural, optical, and photovoltaic properties. X-ray diffraction analysis confirms a predominant cubic perovskite phase in both samples, with Ce doping leading to increased crystal size (21 nm to 32 nm). UV-Vis spectroscopy reveals reduced bandgap energy (2.

Objective: Due to the COVID-19 pandemic, many countries around the world experienced an unprecedented increase in stress in the general population. Even after normal life has been reestablished, the new normal is punctuated by severely impacted vulnerable groups. Stress-associated symptoms display an intricate relationship with biochemical modulations, which coordinate the stress response.

Article Synopsis
- * X-ray diffraction shows that Ce doping increases crystal size and UV-vis spectroscopy reveals a lower bandgap, indicating improved light absorption capabilities.
- * The analysis indicates that CsPbIBr films with Ce doping demonstrate enhanced photovoltaic performance with higher efficiency (9.71% vs. 8.02%) and better stability due to reduced electron-hole recombination.
Article Synopsis
- Burm.f. has properties that help fight infections and was tested to see if it can work better with antibiotics against tough bacteria that don't respond to normal treatments.
- Scientists checked different types of plant extracts for their helpful chemicals and how well they could stop bacteria from growing.
- Results showed some extracts worked really well with the antibiotic cefixime, making it more effective, and could help reduce antibiotic resistance in bacteria.
In this research work, BiO, BiO/GO and BiO/CuO/GO nanocomposites have been synthesized via an eco-friendly green synthesis technique, solgel route and co-precipitation method respectively for the assessment of antibacterial activity as well as in vivo toxicity. The XRD patterns confirm the formation of BiO, BiO/GO and BiO/CuO/GO nanocomposites showing monoclinic structures. Crystallite size and lattice strain are calculated by Scherrer equation, Scherrer plot and Willimson Hall plot methods.

Article Synopsis
- Graphene oxide (GO) is a highly oxidized form of graphene that, when combined with silver nanoparticles (Ag NPs), forms a nanocomposite (GO-Ag) with promising biomedical applications.
- The study evaluated the toxicity of GO-Ag in a human breast cancer model, focusing on how it interacts with photodynamic therapy under different light conditions.
- Results indicated that GO-Ag reduces cell viability in a dose-dependent manner, enhances reactive oxygen species production, and causes cell death through apoptosis, suggesting its potential for targeted breast cancer treatment.
Nickel nanomaterials are promising in the biomedical field, especially in cancer diagnostics and targeted therapy, due to their distinctive chemical and physical properties. In this experiment, the toxicity of nickel nanotubes (Ni NTs) were tested in an in vitro cervical cancer model (HeLa cell line) to optimize the parameters of photodynamic therapy (PDT) for their greatest effectiveness. Ni NTs were synthesized by electrodeposition.
