Chemical looping combustion of wood pellets (WP), char (WC), and straw (SP) was conducted in a 60 kW CLC pilot with ilmenite braunite oxygen carriers (OCs). Alkali emissions were investigated impactor-based surface ionization detector (SID) measurements. Particle size distributions for WP WC fuels dominated by coarse particles formed refractory species. For SP fuel, the distribution bimodal dis...

Lamerin microspridia (Lbms) isolated from Lamerin breed of the silkworm, Bombyx mori, L. and the standard strain Nosema bombycis, were induced to germinate artificially by two-step procedure. Fresh percoll purified spores were activated by incubating them in potassium hydroxide solution (KOH) (pH 11.00) and germinated artificially by using phosphate buffer saline (PBS), (pH 7.00). Germinated sp...

Abstract In this study four kinds of biochars were prepared from the KOH modified biomass. As carbon precursors there was used sawdust following trees: oak, hornbeam, apple and cherry. The physicochemical properties materials characterized by N 2 adsorption, scanning electron microscopy, thermal analysis (TG, DTG DTA), infrared spectroscopy, Boehm’s titration method. Moreover, pH pzc (the point...

This paper deals with the effect of water and catalyst (KOH) amount on the quantity and quality of transesterification products of rapeseed oil by methanol, the methyl ester phase (i.e. yield, conversion), and the side-product, the glycerol phase (i.e. density, viscosity, the mass fraction of glycerol, esters, soaps). The dependencies were described by statistical models. The transesterificatio...

IMPORTANCE Onychomycosis is the most common disease of the nail in adults. International guidelines urge health care professionals to perform confirmatory diagnostic testing before initiating systemic therapy. This approach was determined to be cost-effective in studies from the late 1990s but has not been evaluated more recently. The effect of testing on the costs of efinaconazole, 10%, topica...

Abstract Platelet shaped strontium hexaferrite (SrFe 12 O 19 ) crystallites were hydrothermally synthesized in an autoclave to study the effect of (a) Fe/Sr molar ratio, (b) choice base NaOH/KOH and (c) concentration. The influence these parameters on final product is evaluated with regards phase composition, structure magnetic properties. Rietveld refinements performed powder x-ray diffraction...

This paper presents an in-depth characterization of a raw industrial sludge (IS-R) and its KOH-activated biochar pyrolyzed at 750 °C (IS-KOH-B) followed by their application to remove cationic dye from aqueous solution. Materials shows that compared the IS-R, IS-KOH-B has improved structural, textural, surface chemical properties. In particular, IS-KOH-B’s BET area total pore volume are about 7...
