Evaporation-Induced Reticular Growth of UiO-66_NH in Chitosan Films: Adsorption of Iodine.
ACS Appl Mater Interfaces
January 2025
Metal-organic frameworks (MOFs) combined with polymers as hybrid materials offer numerous advantages such as enhanced performances through synergistic effects at their interface. The primary challenge in developing polymer/MOF hybrid matrix films is ensuring optimal dispersion and strong adhesion of crystalline MOFs to the polymer without aggregation, weak interaction, or phase separation. In this study, hierarchically porous UiO-66_NH/chitosan (ZrCSx-) films were designed by crystallizing UiO-66_NH within a chitosan (CS) skeleton.

- Researchers are tackling the challenge of creating functional materials that direct heat flow in specific ways to improve thermal management.
- They used a technique called spatiotemporally resolved thermoreflectance to study how heat moves in supercrystals made from anisotropic gold (Au) nanocrystals, finding that heat flows more easily along the long axis of these nanocrystals.
- By adjusting the shape of the nanocrystals, they demonstrated increased control over heat directionality, and they used simulations to understand this behavior, offering insights for future applications in thermal management technologies.
Article Synopsis
- Anthropogenic litter, specifically plastic, significantly impacts ecosystems, and scientists from various fields are working together to assess and reduce these pollutants.
- The research aimed to determine the best methods for monitoring macroplastic litter in rivers and oceans by surveying 46 researchers who evaluated different techniques such as visual census, drone surveys, satellite imagery, and GPS/GNSS trackers.
- Results indicated that traditional visual census and drone use were the most favored methods (scoring 3.5 and 2.0), while satellite imagery and GPS trackers were less effective due to validation challenges and range limitations, with scores below 1.2.
Introduction: Multi-drug-resistant (MDR) Pseudomonas aeruginosa is a dangerous pathogen causing nosocomial infection, particularly in low- and middle-income countries like Brazil. This retrospective study at a Brazilian university hospital examined the relationship between antimicrobial use and MDR-P. aeruginosa.

- This study investigates the frequency of alloimmunization among patients at a Brazilian university hospital, focusing on demographic and clinical characteristics of those with positive irregular antibody screenings.
- Findings reveal that women were more likely to be alloimmunized, with common blood groups A and O, and anti-D, anti-E, and anti-Kell antibodies frequently detected.
- The research emphasizes the importance of thorough antibody screening and erythrocyte immunophenotyping to enhance the safety and effectiveness of blood transfusions in clinical settings.
