The Catalytic Effect of Vanadium on Sorption Properties of MgH-Based Nanocomposites Obtained Using Low Milling Time.

The effects of catalysis using vanadium as an additive (2 and 5 wt.%) in a high-energy ball mill on composite desorption properties were examined. The influence of microstructure on the dehydration temperature and hydrogen desorption kinetics was monitored.

Nano/Microcarriers in Drug Delivery: Moving the Timeline to Contemporary.

Treatment of various diseases, especially cancer treatment, includes the potential use of different types of nanoparticles and nanostructures as drug carriers. However, searching for less toxic and more efficient therapy requires further progress, wherein recent developments in medicine increasingly include the use of various advanced nanostructures. Their more successful application might be achieved by leveling imbalances between the potentiality of different nanostructures and the demands required for their safe use.

Influence of Defects on the Stability and Hydrogen-Sorption Behavior of Mg-Based Hydrides.

This review deals with the destabilization methods for improvement of storage properties of metal hydrides. Both theoretical and experimental approaches were used to point out the influence of various types of defects on structure and stability of hydrides. As a case study, Mg, and Ni based hydrides has been investigated.

In-Situ and Real-time Monitoring of Mechanochemical Preparation of Li Mg(NH BH ) and Na Mg(NH BH ) and Their Thermal Dehydrogenation.

For the first time, in situ monitoring of uninterrupted mechanochemical synthesis of two bimetallic amidoboranes, M Mg(NH BH ) (M=Li, Na), by means of Raman spectroscopy, has been applied. This approach allowed real-time observation of key intermediate phases, and a straightforward follow-up of the reaction course. Detailed analysis of time-dependent spectra revealed a two-step mechanism through MNH BH ⋅NH BH adducts as key intermediate phases which further reacted with MgH , giving M Mg(NH BH ) as final products.
