In this work, the effect of immobilization of bread yeast (Saccharomyces cerevisiae) by sol-gel technique combined with functionalized nanoporous silica was investigated in different weight ratios of silica containing materials (TMOS: LUS-1). The activities of immobilized yeast in days after immobilization were examined. The results showed immobilization maintain the yeast life for a longer tim...

Combustion processed nickel oxide (NiOx) thin film is considered as an alternative to the sol-gel hole transport layer for perovskite solar cells (PSCs). In this paper, NiOx was prepared by solution–combustion process at 250 °C, a temperature lower than actual reaction temperature. Furthermore, properties of (HTL) in PSCs were enhanced incorporation zinc (Zn) films. X-ray diffraction and photoe...

-The performance of catalysts in different forms was investigated for the design of a catalytic combustor with hydrogen fuel. The catalysts tested had dimensions of 150 x 150 mm, and consisted of a ceramic honeycomb impregnated with Pt, two Ni metal foams coated with Pd powder which differed from each other in pore size, and a ceramic foam coated with Co-Mn-Ag oxide powder. In the diffusive mod...

We compare results for iodine quantitation by x-ray fluorescence of excised thyroid glands with results of the quantitation by means of an original, newly developed chemical method, a Schöniger combustion technique, in which iodie is quantitated potentiometrically. Subsequently, we establish the accuracy and clinical suitability of the former technique in quantifying the intrathyroidal iodine.

There are many incentives to increase the fuel efficiency of combustion processes. This paper looks at two available options to achieve this goal. The former aims to develop an experimental method that can analyze combustion at extremely high pressures to improve the understanding of high pressure H2/air combustion. Experimental data has been lacking a suitable combustion diagnostic to visualiz...
