Wearable thermoelectric generators (TEGs) are considered as a promising power supply for low wearable electronics. To obtain high (TE) generation, the focus should be on two main factors, including TE materials and configurations of legs. Concerning these this paper provides comprehensive review recent studies TEGs. In general, can classified into three categories, inorganic, organic, hybrid (i...

Segregation defects greatly affect the service performance and working life of castings during vacuum arc remelting (VAR) process. However, corresponding research on prediction segregation is still not comprehensive. Through considering influence water-cooled crucible electromagnetic field inside an ingot, a full-scale model for comprehensive freckles macrosegregation VAR process developed in t...

The purpose of this paper is to show the results of some work at the IRC in Materials for High Performance Applications at the University of Birmingham into the effect of processing and process parameters on the microstructure, macrostructure and chemistry of 100 mm diameter single plasma-melted ingots of a gamma-based titanium aluminide (Ti-48at%Al-2at%Mn-2at%Nb). The microstructure of the aqm...

The mandrel reaming forging is of great significance to the billeting ring ingot. Through analysis deformation steel ingot mandrel, it concluded that exists in radial, axial and tangential directions, which are similar rigid zone, active plastic zone passive upsetting theory. Numerical simulation methods used analyze verified has a an directions. At same time, reduction rate found greater impac...

An etch resistance phase was found in dental silver amalgam when the amalgam was examined metallographically. This phase was common to the silver alloy ingot as well as to its prepared amalgam. Qualitative electron microprobe technics were used to identify this phase. Quantitative electron microprobe analysis defined it as the R' phase of the copper-tin system or the intermetallic compound Cu6Sn5.

The six independent elastic constants of Sr2RuO4 were determined using resonant ultrasound spectroscopy on a high-quality single-crystal specimen. The constants are in excellent agreement with those obtained from pulse-echo experiments performed on a sample cut from the same ingot. A calculation of the Debye temperature using the measured constants agrees well with values obtained from both spe...

BACKGROUND More than 3.5 billion people are affected by iron-deficiency anaemia (IDA). Previous studies have shown that the use of iron pots in daily cooking ameliorates IDA. We report a study on the use of a novel treatment to address IDA in rural women in Cambodia, where the use of iron pots is not common. METHODS A community-wide randomized controlled trial was conducted in the village of ...

Early stage material quality control directly after crystallization is becoming increasingly sophisticated. It is enabled through the characterization of various material parameters along the silicon ingot/brick side faces. Photoluminescence techniques can provide quantitative measures for example of the important photovoltaic material parameter of bulk lifetime. It can measure this parameter w...
