Biomimetic 3D Prototyping of Hierarchically Porous Multilayered Membranes for Enhanced Oil-Water Filtration.

This study introduces a biomimetic approach to 3D printing multilayered hierarchical porous membranes (MHMs) using Direct Ink Writing (DIW) technology. Fabricated through a fast layer-by-layer printing process with varying concentrations of pore-forming agents, the produced MHMs mimic the hierarchical pore structure and filtration capabilities of natural soil systems. As a result, the 3D-printed MHMs achieved an impressive oil rejection rate of 99.

Comparative evaluation of silver diamine fluoride, glass ionomer cement, and calcium hydroxide for indirect pulp therapy in young permanent molars: A randomized controlled trial.

Objectives: Comparative evaluation of indirect pulp therapy (IPT) with silver diamine fluoride (SDF), Type VII glass ionomer cement (GIC), and calcium hydroxide (Ca(OH)2) in young permanent molars.

Materials And Methods: This was randomized controlled trial, in which 45 children with 60 young permanent first molars were allocated as; Group A: IPT with SDF, Group B: Type VII GIC, and Group C: Ca(OH)2. Clinical and radiographic evaluation and comparison was done at baseline, 3, 6, 12 months.

Nipah virus survey in of eastern and northeastern region of India, 2022-2023.

Introduction: India has experienced seven outbreaks of the Nipah virus (NiV) since 2001, primarily occurring in the southern and eastern regions of the country. The southern region has been the main site for these outbreaks. In contrast, the eastern region, which borders Bangladesh, has not reported any outbreaks since 2007.

Mechanobactericidal nanotopographies for food industry: A promising strategy for eradicating foodborne pathogens - progress and challenges.

Nowadays, food preservation, quality maintenance, and safety are major emerging concerns in the food industry. Methods for removing pathogens from the outside surfaces of food products would be an effective way to prevent bacterial contamination. Nanotopographies found on natural surfaces have been shown to mechanically damage the membranes of foodborne bacteria.
