Hydroxyl Radical Generating Monovalent Copper Particles for Antimicrobial Application J. Nanomater. (IF 3.791) Pub Date : 2023-4-25 Tze Hao Tan, Hao Zhang, Bingqiao Xie, Riti Mann, Lingyi Peng, Sung Lai Jimmy Yun, Rose Amal, Zi Gu, Cindy Gunawan
The antimicrobial properties of copper are well-known but maintaining a low oxidation state of Cu in particles is difficult. Herein, antimicrobial CuxP particles were synthesized through phosphorization of Cu(OH)2, to lock copper in its monovalent state (as Cu3P). We found that the phosphorization could be achieved at temperatures as low as 200°C, with stable surface presence of Cu(I) on the resulting

Experimental Evaluation of Lightning and Weather Alert Methods in Rural India using LoRa and IoT Technology with Nanosensors J. Nanomater. (IF 3.791) Pub Date : 2023-4-21 Ome Nerella, Syed Musthak Ahmed, Praveen Balakrishnan
Every year, ∼2,000 people are killed by lightning in India, with rural areas accounting for 94% of all lightning deaths. In rural locations, a weather and lightning alert system is crucial for alerting and raising awareness about severe weather and lightning. Only a few states in India have expensive lightning alert systems that send out alerts via SMS and mobile apps. Due to a lack of information
