Background: Tobacco use is one of the leading causes of death in the world. Dentists play a vital role in tobacco abstinence and counseling. Dental institution being a foundation for a clinical practice from where they can practice and implement the habit of tobacco counseling.

Chitosan functionalized AgNPs for efficient removal of Imidacloprid pesticide through a pressure-free design.

Wide dissemination of pesticides for protecting plants against pests has resulted in high production of un-infected crops but higher environmental pollution. High percentages of pesticides are released to the environment and finally use water as the final destination. The current study is concerning by removal of Imidacloprid pesticide from water using pressure-free passage through polymeric membrane integrated design.

Potential Decontamination of Drinking Water Pathogens through k-Carrageenan Integrated Green Bottle Fly Bio-Synthesized Silver Nanoparticles.

The wide distribution of infections-related pathogenic microbes is almost related to the contamination of food and/or drinking water. The current applied treatments face some limitations. In the current study, k-carrageenan polymer was used as supporting material for the proper/unreleased silver nanoparticles that showed strong antimicrobial activity against six pathogenic bacteria and yeast.
