Morphology Effects on Electro- and Photo-Catalytic Properties of Zinc Oxide Nanostructures.

Environmental problems are among the most pressing issues in the modern world, including the shortage of clean drinking water partially caused by contamination from various industries and the excessive emission of CO primarily from the massive use of fossil fuels. Consequently, it is crucial to develop inexpensive, effective, and environmentally friendly methods for wastewater treatment and CO reduction, turning them into useful feedstocks. This study explores a unique method that addresses both challenges by utilizing ZnO, which is recognized as one of the most active semiconductors for photocatalysis, as well as a cost-effective electrocatalyst for the CO reduction reaction (CORR).

Effect of Hydrogen Plasma Treatment on the Sensitivity of ZnO Based Electrochemical Non-Enzymatic Biosensor.

Information on vitamin C-ascorbic acid (AA)-content is important as it facilitates the provision of dietary advice and strategies for the prevention and treatment of conditions associated with AA deficiency or excess. The methods of determining AA content include chromatographic techniques, spectrophotometry, and electrochemical methods of analysis. In the present work, an electrochemical enzyme-free ascorbic acid sensor for a neutral medium has been developed.

Highly Sensitive Zinc Oxide Fiber-Optic Biosensor for the Detection of CD44 Protein.

Currently, significant progress is being made in the prevention, treatment and prognosis of many types of cancer, using biological markers to assess current physiological processes in the body, including risk assessment, differential diagnosis, screening, treatment determination and monitoring of disease progression. The interaction of protein coding gene CD44 with the corresponding ligands promotes the processes of invasion and migration in metastases. The study of new and rapid methods for the quantitative determination of the CD44 protein is essential for timely diagnosis and therapy.

Stabilization of the Surface of ZnO Films and Elimination of the Aging Effect.

Zinc oxide is a promising multifunctional material. The practical use of nano- and polycrystalline ZnO devices faces a serious problem of instability of electrical and luminescent characteristics, due to the adsorption of oxygen by the surface during aging. In this paper, the aging effect in ZnO films and nanorod arrays was studied.

[The use of immunomodulators to enhance postvaccinal immunity to experimental poliomyelitis].

A possibility to use immunostimulator dibasole and methyluracil to increase [correction of decrease] the level of neutralising antibodies to polioviruses [correction of polyviruses] of types I, II, III in response to immunization by the alive poliomyelitis vaccine was studied in experiments on rabbits. The higher level of immune response when using the mentioned drugs, especially methyluracil, has been established; repeated immunization is needed to develop antibodies to poliovirus [correction of polyavirus] of type III.
