Ecologically sustainable biodegradable polymers fabricated from banana peel pectin reinforced with silver zeolite nanoparticles (Ag/zeolite NPs).

In the present investigation, the formulation and thorough assessment of biodegradable composite films were conducted, utilizing pectin extracted from banana peel in conjunction with synthesized silver zeolite nanoparticles. The evaluation of physical properties, microstructural investigation, mechanical characteristics, and barrier properties was done providing valuable insights into various attributes of the film. The amalgamation of silver zeolite nanoparticles with the extracted pectin from banana peel results in biodegradable composite films exhibiting distinct physical, mechanical, barrier, and thermal properties.

A feedback neural circuit for calibrating aversive memory strength.

Aversive experiences powerfully regulate memory formation, and memory strength is proportional to the intensity of these experiences. Inhibition of the neural circuits that convey aversive signals when they are predicted by other sensory stimuli is hypothesized to set associative memory strength. However, the neural circuit mechanisms that produce this predictive inhibition to regulate memory formation are unknown.
