1. Evidence has been presented in this paper which greatly strengthens the suggestion that the spherical particles lining the inner membranes of mitochondria are the morphological representations of coupling factor 1 (ATPase). 2. With tritum-labeled ATPase it was shown that treatment of reconstituted particles with 2 M urea leads to a release of radioactivity which corresponded to the disappear...

A method is developed for electro-deposition of thin films of the conducting polymer polythiocyanogen on conducting tin oxide glass or other conducting substrate by anodic discharge of SCN− ions form a solution KSCN in propylene carbonate. Films are found to be highly stable and resistant to heat and chemical action. SEM pictures indicate that the films are uniform and free of pin hole. Band ga...

In this paper, cobaltporphyrin is used as a precursor to synthesize carbon nitrides with metal active sites supported on silica spheres by heat treatment (i.e. M-N-C/SiO2). The catalytic performance of M-N-C/SiO2 for ethylbenzene oxidation has been investigated and techniques such as N2 adsorption/desorption isotherm, NH3-TPD, HRTEM, STEM mapping and X-ray photoelectron spectroscopy (XPS) are e...

Cellulose derivatives (Figure 1) have many important commercial applications in the fiber, paper, membrane, polymer and paints industries. However, there are only a limited number of common solvents in which cellulose is soluble; solvents include, carbon disulfide, N,Ndimethylacetamide/lithium chloride (DMAC/LiCl), concentrated inorganic salt (ZnCl/H2O, Ca(SCN)2/H2O) and mineral acids (H2SO4/H3...

Resonant and nonresonant intermolecular vibrational energy transfers in KSCN/KSC(13)N/KS(13)C(15)N aqueous and DMF solutions and crystals are studied. Both energy-gap and temperature dependent measurements reveal some surprising results, e.g. inverted energy-gap dependent energy transfer rates and opposite temperature dependences of resonant and nonresonant energy transfer rates. Two competing ...

In this work, the one step electrodeposition process was used to prepare Ag-In-Se thin films. The films were deposited at room temperature from a bath containing 1-3x10 M AgNO3, 6x10 -2 M InCl3 and 3x10 -2 M of H2SeO3. The KSCN at a concentration of 0.681 M was used as complexing agent. The pH value of the solution was 1.4. Applied potentials to SCE were chosen between -0.3 V and -1.1 V. Films ...

Granum-containing chloroplasts from mesophyll cells of maize (Zea mays L. var. MV 861) leaves exhibited circular dichroism spectra with a large double signal; peaks at 696 nm (+) and 680 nm (-). In the circular dichroism spectra obtained with agranal chloroplasts of bundle sheath cells, this large double signal is absent. Separation of grana lamellae, in a medium of low salt concentration and i...

In this investigation, a novel temperature-pH responsive copolymer was prepared by the radical copolymerization between 2-hydroxypropyl acrylate (HPA) and aminoethyl methacrylate hydrochloric salt (AMHS). The molecular structure of the corresponding copolymer has been confirmed by 1H NMR and FTIR measurements. The results indicated that the lower critical solution temperature (LCST) of the resu...

P. Vaňová, J. Sojka. VŠB Technical u niversity of O strava, FMME, Ostrava, Czech Republic This paper is dealing with hydrogen embrittlement of austenitic-ferritic 2205 duplex steel using the slow strain rate test (SSRT). The original material was subjec ted to heat treatment under 700 °C during 5 hours and f ollowing aircooling with the aim of pr ovoking sigma phase pr ecipitation and embrittle...
