A systematic review and meta-analysis of exercise-based intervention to prevent gestational diabetes in women with overweight or obesity.

Background: There is evidence that exercise may reduce the risk of gestational diabetes mellitus (GDM) and improve other obstetric outcomes in overweight or obese pregnant women. However, the available evidence is of low quality and inconclusive. The purpose of this study is to assess the effects of exercise, compared with usual care, in reducing GDM and other obstetric risks, in overweight and obese pregnant women.

Enhancement of effluent degradation by zinc oxide, carbon nitride, and carbon xerogel trifecta on brass monoliths.

In recent years, heterogeneous photocatalysis has emerged as a promising alternative for the treatment of organic pollutants. This technique offers several advantages, such as low cost and ease of operation. However, finding a semiconductor material that is both operationally viable and highly active under solar irradiation remains a challenge, often requiring materials of nanometric size.

Resembling Graphene/Polymer Aerogel Morphology for Advancing the CO/N Selectivity of the Postcombustion CO Capture Process.

The separation of CO from N remains a highly challenging task in postcombustion CO capture processes, primarily due to the relatively low CO content (3-15%) compared to that of N (70%). This challenge is particularly prominent for carbon-based adsorbents that exhibit relatively low selectivity. In this study, we present a successfully implemented strategy to enhance the selectivity of composite aerogels made of reduced graphene oxide (rGO) and functionalized polymer particles.

Innovative Strategy for Developing PEDOT Composite Scaffold for Reversible Oxygen Reduction Reaction.

Metal-air batteries are an emerging technology with great potential to satisfy the demand for energy in high-consumption applications. However, this technology is still in an early stage, facing significant challenges such as a low cycle life that currently limits its practical use. Poly(3,4-ethylenedioxythiophene) (PEDOT) conducting polymer has already demonstrated its efficiency as catalyst for oxygen reduction reaction (ORR) discharge as an alternative to traditional expensive and nonsustainable metal catalysts.
