Synthesis and comparative study of the structural and optical properties of binary ZnO-based composites for environmental applications.

The development of photoactive systems to solve serious environmental problems is a key objective of researchers and remains a real challenge. Herein, n-p heterojunction ZnO-based composites were developed to achieve better photocatalytic performance in methylene blue (MB) degradation under natural solar irradiation. The hydrothermal technique was used to synthesize zinc oxide (ZnO)/metal oxide (MO) composites, with a molar ratio of 1 : 1 (MO = MnO; FeO; CuO; NiO).

Non-doped and transition metal-doped CuO nano-powders: structure-physical properties and anti-adhesion activity relationship.

Bacterial contamination and biofilm formation generate severe problems in many fields. Among these biofilm-forming bacteria, () has emerged as a major cause of nosocomial infection (NI). However, with the dramatic rise in resistance toward conventional antibiotics, there is a pressing need for developing effective anti-biofilms.

Intestinal ischemia in patients with incarcerated groin hernia: proposal and validation of a score.

Purpose: Intestinal ischemia (II) is the most critical factor to determine in patients with incarcerated groin hernia (IGH) because II could be reversible, and it is considered as a "time sensitive condition." Although predictive factors of II were identified in several previous studies, preoperative diagnosis of II cannot be reliably made or excluded by any known parameter. The aims of this study were: to devise and to validate a clinic-biologic score, with a strong discriminatory power, for predicting the risk of II in patients with IGH.

Enhanced photocatalytic activity against crystal violet dye of Co and In doped ZnO thin films grown on PEI flexible substrate under UV and sunlight irradiations.

This work is focused on the photocatalytic activities of undoped ZnO, Co (1%) doped ZnO (CZO) and In (1%) doped ZnO (IZO) thin films grown on flexible PEI (Polyetherimide) substrate by spray pyrolysis. The photodegradation of crystal violet dye was investigated under UV and sunlight irradiations. Doping and excitation energy effects on photocatalytic efficiencies are discussed.
