Germanides are an interesting class of two-component systems which consist metal and germanium. They similar in their structure with silicides but have the specific properties. The target investigation was finding main anodic electrochemical behaviour mechanisms for magnesium germanide Mn5Ge3 Na2SO4 aqueous solution.Electrochemical manganese obtained by Czochralski method investigated polarizat...

Granular films SiO2(Co) exhibit unusual magnetic and magnetotransport properties which are strongly dependent on the composition of film material a substrate. For example, injection magnetoresistance (IMR) coefficient reaches giant (GIMR) value 105% at room temperature in an n-GaAs However, IMR effect is negligible case similar granular deposited n-Si In this report, structural Si substrate stu...

Abstract Phosphate minerals such as those in the apatite group tend to be dominant forms of phosphorus on Earth’s surface. can reduced phosphides during high-energy events, lightning and impacts. Here we show that, addition formation metal phosphides, a new compound was formed by fulgurite from New Port Richey, Florida, USA. A calcium phosphite material, ideally CaHPO 3 , found spherules mainly...

The formation of a single phase is an important requirement for high-entropy ceramics (HECs) because precipitation unwanted phases generally degrades their functional properties. This paper provides useful guideline the single-phase HECs. First, metal elements constituting HECs can be divided into two groups: that have parent as stable and with same stoichiometry but different crystal structure...

The intermetallic compound MoSi2, which adopts the C11b crystal structure, and related alloys exhibit an excellent corrosion resistance at high temperatures but tend to be brittle at room and even relatively high temperatures. The limited ductility of MoSi2 in ambient conditions along with the anomalous temperature dependence of the critical resolved shear stress (CRSS) of the {110)<111], {011)...
