Electrochemically produced hydrogen bubble probes for gas evolution kinetics and force spectroscopy
The development and characterisation of electrochemically generated hydrogen bubbles for gas evolution kinetics and force spectroscopy are described. Bubbles have been grown at the platinised tip of a commercially available atomic force microscopy (AFM) needle probe (exposed electrode radius rb300 nm) and monitored by CCD camera. Results show consistent bubble growth in galvanostatic conditions. The utility of the bubble probes in AFM force spectroscopy

The paper presents the experimental results regarding the influence of the reinforcing elements on the wear behavior of Al-matrix composites discontinuously reinforced by SiC and Graphite. This antifriction composite material is processed by Reactive Mechanically Alloyed and then by Spark Plasma Sintering technology. In order to optimize the processing technology, especially the sintering parameters, the Spark Plasma Sintering process was applied

Romania still has extensive dry grasslands that are outstanding in diversity and conservation status compared to European standards. Land-use change is one of the greatest threats to biodiversity and conservation of these grasslands. Litter accumulation was proved to have a prime role in governing community processes in dry grassland following abandonment by affecting the regeneration from seed of constituent species. Accumulated litter reduces bare
