Effects of sodium ions on synthesized alkali silica reaction gels [PDF]
, 2015 The alkali-silica reaction (ASR), leading to serious structural degradation, is the chemical reaction between reactive silica presenting in aggregates and hydroxyl ions from cement paste or pore solution. Although the chemical mechanism of ASR attack has

Shaping Ti3C2 MXene Nanospheres for Precision Near‐Infrared Photothermal Therapy
Advanced Functional Materials, EarlyView.In this study, we report producing spherical MXenes via fs laser fragmentation of Ti3C2 flakes in liquid medium. The nanoparticles demonstrated pronounced light absorption and high photothermal conversion efficiencies of 68% and 63% under heating with NIR‐I and NIR‐II lasers, respectively.

Dynamics of salt stress parameters in cultivated oat with different pH levels of root environment
Известия высших учебных заведений. Поволжский регион: Естественные науки, 2022 Background. The development of the process of soil salinization can be accompanied by both a decrease and an increase in pH; at the same time, plants experience complex stress (salt + alkaline stress, salt + acid stress). The purpose of the research is
