Contribution of piezoelectric effect on piezo-phototronic coupling in ferroelectrics: A theory assisted experimental approach on NBT.

A new study explores the distinct roles of spontaneous polarization and piezoelectric polarization in piezo-phototronic coupling. This investigation focuses on differences in photocatalytic and piezo-photocatalytic performance using sodium bismuth titanate, a key ferroelectric material. The research aims to identify which type of polarization has a greater influence on piezo-phototronic effects.

Neurotoxic effects of carbamazepine on the mosquitofish .

In recent years, the presence of pharmaceuticals in the aquatic environment has gained a significant attention. Carbamazepine, a commonly prescribed antiepileptic drug, has been consistently found in aquatic environments at concentrations ranging from nanograms to micrograms, raising concerns about its potential negative impacts on aquatic organisms. The study examined the acute and chronic neurotoxic effects of environmentally relevant and sublethal concentrations of carbamazepine in the mosquitofish .

Understanding the depolarization phenomena in (1-) NaBiTiO. () BaCaTiZrOsolid solutions usingtemperature dependent Raman spectroscopy.

A decrease in depolarization temperature () from 456 K to 352 K was observed with an increase in BCZT substitution in the NBT for the (1-) NaBiTiO. () BaCaTiZrOsolid solutions. A transition towards a higher ergodic state was elucidated with an increase in BCZT content that helped to reduce the free energy barrier, hence lesser thermal energy was required to depolarize the modified systems.

Exposure to the plasticizer dibutyl phthalate causes oxidative stress and neurotoxicity in brain tissue.

The phthalate ester, dibutyl phthalate (DBP), is one of the endocrine-disrupting chemicals detected in various aquatic environments. Previous research has found multiple toxic effects of DBP in aquatic organisms; however, the neurotoxic effects of the compound are surprisingly scanty. The purpose of this study was aimed to evaluate the role of oxidative stress in the induction of neurotoxicity in the brain tissue of the fish Pseudetroplus maculatus.

An unusual case of urinary sparganosis in the Indian subcontinent.

is a genus of pseudophyllidean cestode that reproduces in canines and felines but can cause pathology in humans. When humans harbour plerocercoids of these tapeworms outside the intestine, it can cause sparganosis. We report a case of urinary sparganosis in a young woman, passing multiple spargana worms in her urine.
