A comprehensive review of challenges and opportunities for stem cell research in India.

Perspect Clin Res

August 2024

Faculty of Biotechnology, Institute of Biosciences and Technology, Shri Ramswaroop Memorial University, Barabanki, UP, India.

Stem cell research is a major focus for scientific and medical communities worldwide due to the potential for stem cells to restore function lost due to disease, trauma, congenital abnormalities, and aging. Stem cells can repair, replace, or regenerate damaged cells, tissues, or organs, making them an important area of research in regenerative medicine. India is emerging as a prominent hub for the development of stem cell therapy (SCT), and it is important to assess the current state of stem cell research in India and the potential for advancement to promote stem cell-based therapy.

Efficient Orange Light-Emitting Diodes from Nontoxic Organic-Inorganic Hybrid Copper Halides Enabled by Nonionic Surfactant Chemisorption.

Nano Lett

January 2025

Key Laboratory of Materials Physics of Ministry of Education, School of Physics, Zhengzhou University, Daxue Road 75, Zhengzhou 450052, China.

Ternary copper halides with an eco-friendly property have emerged as attractive candidates to replace toxic lead-containing perovskites for light-emitting diodes (LEDs), yet achieving long-wavelength electroluminescence remains unexplored. Herein, we report the first realization of orange-emitting LEDs (595 nm) based on nontoxic organic-inorganic PEACuI (PEA = β-phenylethylamine) films enabled by a nonionic surfactant poly(propylene glycol) bis(2-aminopropyl ether) (APPG) chemisorption. Experimental and theoretical analyses rationalize that the APPG additive has strong chemisorption with the Cu-I framework within the grain boundaries of PEACuI films, which not only improves the film's morphology but also passivates the iodine vacancy defects.

Warping is a crucial process that connects two main stages of production: yarn manufacturing and fabric creation. Two interrelated parameters affect the efficiency of this technological process: warping speed and the ability to swiftly detect the yarn breaks caused by various defects. The faster a break is detected and the warping machine stopped, the higher the machine's working speed can be.

AI, especially ChatGPT, is impacting healthcare through applications in research, patient communication, and training. To our knowledge, this is the first study to examine ChatGPT-4's ability to analyze images of lower leg defects and assesses its understanding of complex case reports in comparison to the performance of board-certified surgeons and residents. We conducted a cross-sectional survey in Switzerland, Germany, and Austria, where 52 participants reviewed images depicting lower leg defects within fictitious patient profiles and selected the optimal reconstruction techniques.
