Research ArticleOpen accessIn the keywordsAppraisal of Thermal Properties of Mud in the Ariake Sea, JapanM. Azizul Moqsud, Shigenori Hayashi, Yan Jun Du, Daisuke SuetsuguIn order to explore the thermal properties of the Ariake Sea mud and to find out the affecting factors which affect these values, a portable thermal properties analyzer was used. Thermal conductivity, thermal resistivity, thermal diffusivity and volumetric heat capacity of the mud samples collected from both the tidal flat and inside the deep sea were measured in the laboratory. … …American Journal of Environmental Sciences, Vol. 4, Issue 2 · 30 Apr 2008 · 6,966 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThermal Treatment Effects on the Thermoelectric Properties of Ni/Si/Si + Sb/Si/Si + Ge/Ni Multilayer Thin FilmsSatilmis Budak, Zhigang Xiao, Shujun YangThe multilayer thermoelectric devices including Ni/200 layers of Si/Si + Sb/200 layers of Si/Si + Ge/Ni thin films were fabricated using electron beam and DC/RF magnetron sputtering deposition systems. The thickness measurements have been performed using Filmetrics UV thickness measurement system. The Au contacts at the bottom and top of the fabricated thermoelectric devices were measured as 100 nm for … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 4 · 14 Nov 2020 · 6,710 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffects of Moisture Content on Thermal Properties of Adobe Bricks as a Sustainable Building MaterialSuleman Modu NgaramThe adobe is a widely used traditional material in popular building construction in rural areas of Northeastern, Nigeria and more generally in African countries. In order to increase comfort and energy efficiency of buildings, it is necessary to better consider the thermal properties of the adobe. Adobes at different locations as a function of moisture content have been studied. Thermal … …American Journal of Applied Sciences, Vol. 17, Issue 1 · 15 Apr 2020 · 10,256 accessesView PDF Cite

Research ArticleOpen accessIn the abstractHighly-Efficient Advanced Thermoelectric Devices from Different Multilayer Thin FilmsSatilmis Budak, Zhigang Xiao, Barry Johnson et al.The efficiency of the thermoelectric materials and devices is shown by the dimensionless Figure of merit, ZT. ZT is calculated by multiplying the Seebeck coefficient with square of the electrical conductivity and absolute temperature and dividing it all by the thermal conductivity. Thermoelectric devices were prepared using different multilayered thin film structures in the order of SiO2/SiO2 + Ge/Ge/Sb + … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 2 · 27 Apr 2016 · 8,368 accessesView PDF Cite
