Application of zeolites for efficient tannery wastewater remediation.

Leather manufacturing is the process of converting raw animal hides or skins into finished leather. The complex industrial procedures result in a tanning effluent composed of chemical compounds with potentially hazardous impacts on humans and ecosystems. Among the traditional and efficient wastewater treatments, adsorption is an effective and well-known approach, able to manage a wide range of contaminants from wastewater.

Delayed postoperative impedance issues in patients treated with deep brain stimulation: A single-center retrospective study.

Background: In rare circumstances, an implanted deep brain stimulation device will develop impedance issues across its contacts. Even more rare is the resultant inability to program a patient effectively, or that the patients' prior programming settings become unusable.

Objective: In this study we investigate this occurrence across the device manufacturers implanted, and whether this could be resolved.

Zeolite Additives for Flexible Packaging Polymers: Current Status Review and Future Perspectives.

Zeolites are interesting inorganic additives that could be employed for plastic packaging applications. Polyethylene (PE) and polypropylene (PP) are intensively used for packaging as they provide great performance at low cost, even though they have poor environmental sustainability and may be more valorized. Biodegradable polymers may therefore represent a more eco-friendly alternative, but still, they have limited applications due to their generally inferior properties.

Mobility Gaps of Hydrogenated Amorphous Silicon Related to Hydrogen Concentration and Its Influence on Electrical Performance.

This paper presents a comprehensive study of hydrogenated amorphous silicon (a-Si)-based detectors, utilizing electrical characterization, Raman spectroscopy, photoemission, and inverse photoemission techniques. The unique properties of a-Si have sparked interest in its application for radiation detection in both physics and medicine. Although amorphous silicon (a-Si) is inherently a highly defective material, hydrogenation significantly reduces defect density, enabling its use in radiation detector devices.
