In situ synthesis of ZnO/g-CN based composites for photodegradation of methylene blue under visible light.

In this study, in situ-synthesized ZnO/g-CN based composites were used as photocatalysts for organic pollution removal. These nanocomposites were prepared through simple calcination of a mixture of melamine and ZnO nanoparticles and underwent comprehensive evaluation of their structural, morphological, optical, and photocatalytic properties, using various analytical techniques. As the g-CN content increased, the band gap decreased from 3.

Facile synthesis of spongy NiCoO powders for lithium-ion storage.

Spongy NiCoO powders were prepared by solution combustion synthesis (SCS) method for lithium ions storage. The effects of combustion parameters including fuel type (L-lysine, glycine, and urea) and fuel amount on the lithium storage performance of NiCoO powders were analyzed by various characterization techniques. Single-phase NiCoO powders with extremely porous microstructure showed a strong drop of initial specific capacity up to 350 mAhg which was recovered up to 666 mAhg following 100 charge/discharge cycles.

The relationship between social determinants of health and fear of contracting infectious diseases in pregnant women presenting to health centers in Kashan, Iran: a path analysis study.

Introduction: Pregnancy is one of the most critical times in a woman's life that is accompanied by a lot of worry, fear, and stress for the mother, and fear of contracting diseases and losing the children are among the most important of them. The present study investigated the relationship between the social determinants of health and fear of contracting infectious diseases in pregnant women using path analysis.

Methods: This cross-sectional study was conducted on 330 pregnant Iranian women in Kashan from September 21th, 2021, to May 25th, 2022, using a multi-stage method.

Targeted gene delivery to the brain using CDX-modified chitosan nanoparticles.

Blood-brain barrier with strictly controlled activity participates in a coordinated transfer of bioactive molecules from the blood to the brain. Among different delivery approaches, gene delivery is touted as a promising strategy for the treatment of several nervous system disorders. The transfer of exogenous genetic elements is limited by the paucity of suitable carriers.
