Influence of Sample Preparation and Processing Procedures on the Thermal Diffusivity of MgO‐C Refractories

Advanced Engineering Materials, EarlyView.
The thermal diffusivity of MgO‐C refractories is highly sensitive to sample preparation and processing procedures. In this article, the effects of coking sequence, machining conditions, structural inhomogeneity, and graphite coating application on measurements using laser flash apparatus are systematically investigated.

Ball Milling Promoted N-Heterocycles Synthesis [PDF]

Molecules, 2018
In the last years, numerous protocols have been published using ball milling for organic synthesis. Compared to other methods such as microwave or ultrasound irradiation and ionic liquids, ball mill chemistry is an economical, and ecofriendly method in organic synthesis that is rather underrepresented in the knowledge of organic chemists.

Thermoelectric Modules Incorporating MgAgSb and Mg3(Sb,Bi)2 Synthesized Using a Melting Method

Advanced Engineering Materials, EarlyView.
A scalable synthesis method for a thermoelectric material of MgAgSb is established. A thermoelectric power module of MgAgSb/Mg3(Sb,Bi)2 is fabricated, showing the conversion efficiency of 7.4% at ΔT = 315 K. The performance is comparable to conventional Bi2Te3 modules when they are operated with an air‐cooled heat exchanger.
