In the present study, the sintering behavior of a commercial nano alumina powder with an initial particle size of 100 nm was investigated. The shrinkage response of the powder formed by pressure filtration (PF) during non-isothermal sintering was measured ...
Extending the idea of exergy to practitioners and policy makers is still a major challenge. Recently the "Canton of Geneva" in Switzerland introduced a new law governing the procedures of attribution of building permits for new or retrofitted city areas. A ...
In the application of solid-state NMR to many systems, the presence of radiofrequency (rf) electric fields inside classical solenoidal coils causes heating of lossy samples. in particular, this is critical for proteins in ionic buffers. Rf sample heating i ...
We report here on an integrated mini-lamp module (15x26x4 mm3) with a microfabricated rf-powered Rb dielectric barrier discharge (DBD) lamp (10x10x3 mm3) positioned on top of a 0.6 mm thick (thickness adjustable) 4-layer LTCC (Low Temperature Co-fired Cera ...
Recent JET experiments have been devoted to the study of (He-3)-D plasmas involving radio frequency (RF) heating. This paper starts by discussing the RF heating efficiency theoretically expected in such plasmas, covering both relevant aspects of wave and o ...
In a moulding process, in particular in a bladder inflation moulding (BIM process) a thin walled mould is machined to the exact shape of the part to avoid any post machining of the part after stripping. The heating is performed in a liquid tin bath, used t ...
Localized electron heating and current drive, like those produced by electron cyclotron heating (ECH) systems, are powerful tools for controlling the sawtooth period. They allow the direct modification of the plasma parameters which determine the sawtooth ...
Epoxidation of (1RS,2SR,3SR,4RS,6RS,7RS,8RS, 12RS, 13RS)-6,13-bis(benzyloxy)-15,16-dioxapentacyclo[10. 2.1.1(4.7).0(2,11).0(3.8)]hexadec-10-en-8-yl-methanol (12) led to the stereoselective formation of (1RS,2RS,3RS,5RS,6SR, 7RS,8RS, 10RS,11SR, 12SR,16SR)-3 ...
Thermal comfort depends on heat exchanges of the body by conduction evapo-transpiration and convection to the air, and radiation to and from surrounding surfaces. Usual ways of sizing heating and cooling systems are based on homogeneous temperature in the ...
A complex heating and cogeneration plant including two 3.9 MWth ammonia heat pumps and two 3 MWel gas turbines with heat recovery boilers and three storage tanks of 66 GJ has been in operation since 1986. The heating surface is actually about 280’000 m2 an ...
