Osteoconductive Effect of a Nanocomposite Membrane Treated with UV Radiation

Modulation of the bio-regenerative characteristics of materials is an indispensable requirement in tissue engineering. Particularly, in bone tissue engineering, the promotion of the osteoconductive phenomenon determines the elemental property of a material be used therapeutically. In addition to the chemical qualities of the constituent materials, the three-dimensional surface structure plays a fundamental role that various methods are expected to modulate in a number of ways, one most promising of which is the use of different types of radiation. In the present manuscript, we demonstrate in a calvarial defect model, that treatment with ultraviolet irradiation allows modification of the osteoconductive characteristics in a biomaterial formed by gelatin and chitosan, together with the inclusion of hydroxyapatite and titanium oxide nanoparticles.

Covalent Organic Polymers with Solid-State Dual-Color Fluorescence Tunable by Ultraviolet Irradiation

An aldol condensation-based strategy is developed for preparing covalent organic polymers (COPs) with strong solution and solid-state dual fluorescence. Moreover, the fluorescence property can be facilely tuned by two ways:...

Усиление гидрофобных свойств структур ZnO золотым покрытием

The effect of enhancement the hydrophobic properties of the ensemble of micro- and nanostructures ZnO as a result of coating with gold was discovered. For the first time, it has been shown that coating the ensemble with a micro- and nanoparticle ZnO layer of gold leads to a sharp increase in the wetting edge angle from 145 to 168 ° (water drop volume 5 mm3) and a decrease in the hydrophobicity/hydrophilicity transition time under ultraviolet irradiation. Keywords: ZnO, gold, superhydrophobic.

Transformation of carbon dots by ultraviolet irradiation, ozonation, and chlorination processes: Kinetics and mechanisms

As a new carbon nanomaterial, carbon dots (CDs) with unique physicochemical and luminescent properties have wide-ranging applications. Once released into the water and wastewater treatment plants, CDs will undergo physicochemical...

UV treatment of agricultural plants in territories subject to salination of soil

An assessment of the influence of electrotechnology of ultraviolet irradiation of seeds and pre-sowing soil treatment and the creation, on their technological basis, of management and control of salt and nutritional regimes of irrigated soils has been carried out. Relative yield of field crops versus the concentration of toxic salts in the soil solution at full moisture capacity are shown. By results of experimental researches acting of UV irradiation on the amount of ammonifying bacteria in the soil under cotton for increasing the accumulation of the most mobile nitrate forms of nitrogen are defined.
