Gold nanobelts were synthesized by directional solidification of the Fe-Au eutectoid followed by selective phase dissolution. Cleaning from organic molecules was performed in alkaline solution by PbO 2 deposition/dissolution to avoid surface reconstr

An in situ tensile rig is proposed, which allows performing electrochemical (repassivation) experiments during dynamic mechanical testing of wires. Utilizing the basic components of a conventional tensile tester, a custom-made minitensile rig was des

This work describes a novel fabrication method of single crystalline Mo nanowires and nanowire arrays. The method utilizes directional solidification (ds) of a NiAl-Mo eutectic alloy and its subsequent electrochemical processing. In the first step, a

Automatized microelectrochemical investigations are achieved using a scanning droplet cell. The area reproducibility for a 100 mum oxide spot is found to be better than 1%, a value typically difficult to reach even in macroscopic samples. A systemati

Single crystalline tungsten nanowires were prepared from directionally solidified NiAl-W alloys by a chemical release from the resulting binary phase material. Electron back scatter diffraction (EBSD) proves that they are single crystals having ident

Corrosion of iron presents a serious economic problem. Whereas aerobic corrosion is a chemical process, anaerobic corrosion is frequently linked to the activity of sulphate-reducing bacteria (SRB). SRB are supposed to act upon iron primarily by produ

Reasearch on photocatalysts is rapidly increasing. They will hopefully help us solving or at least reducing our energy problems. Heterogeneous and homogeneous catalysts are considered in various approaches. The preparation of modified or entirely new
