During the last 2 years, the knowledge on the metabolic pathway of tetrazepam, a muscle relaxant drug, was expanded by the fact that diazepam was identified as a degradation product of tetrazepam. The present study demonstrates that this metabolic conversion, recently discovered by in vivo studi...

SummaryThe crystal structure of tetrazepam, a benzodiazepine derivative formerly used for its muscle relaxant properties, has been solved and found to be monoclinic, space group P21/c, with lattice parameters a = 12.7386(7) Å, b = 11.3774(7) Å, c = 10.3084(7) Å, β = 103.175(5) and Vunit-cell = ...

A simple specific flow injection spectrophotometric method for the determination of trimeprazine tartrate is described. In the method, 123 μl of the drug is injected on line with 0.00122 M cerium(IV) carrier stream already prepared in 0.75 M sulfuric acid. The oxidized species of the drug is mo...

Hydrolysis of Transferin (Tf), a glycoprotein consisting of 679 amino acids and three glycan chains, has been examined in the presence of Ce(IV)-substituted Keggin polyoxometalate [CeIV(α-PW11O39)2]10− (Ce-K POM). Incubation at pH = 7.4 and at 37 °C resulted in selective fragmentation of the T...

Solubilization of membrane proteins by poly(styrene-co-maleic acid) salts (pSMA-S) has significant potential for membrane protein studies. This approach provides an opportunity to overcome many disadvantages associated with a traditional detergent-based technique including protein denaturation a...

The chemiluminescence arising from the reaction of bis(2,4,6-trichlorophenyl)oxalate (TCPO) with hydrogen peroxide in the presence of brightener 4,4′-bis{[4,6-bis(2-hydroxyethyl)amino-1,3,5-triazin-2-yl]amino}stilbene-2,2′-disulfonic acid-disodium salt (Triazinyl) has been studied. The influen...

This research work explored the synthesis and characterization of magnetic manganese ferrites using a simple combustion method. The purpose of creating the magnetic manganese ferrites was for their planned use as ozonation catalysts. Their magnetic properties allow for their recovery from the tr...

A novel organic-modified aluminum‑manganese bimetal oxide (OABO) adsorbent was fabricated to adsorb nitrate and phosphate from wastewater and reduce eutrophication risk. Several techniques were applied to investigate the surface characteristics of OABO. The characterization results showed that O...

The paper presents a novel simple and cost-effective approach to preparation of mixed-valence mesoporous manganese oxide in the form of easy to handle spheres. The synthesis relies on swelling of porous polymer templates (i.e. three selected resins Amberlite® XAD7 HP, XAD4 and XAD16) in a satura...

Graphene had been studied as a macro-scale solid lubricant intensively due to its excellent tribological properties. The electrophoretic deposition (EPD) was supposed to be an effective method of fabricating graphene-related materials, but it was not naturally applicable to the inherently unchar...

In the centralized solar power generation system, the molten salt is a key component for storing and transferring heat energy. By adding Mg(NO3)2 to NaNO3 at various mass ratios, nine binary nitrate specimens were prepared.The melting point, decomposition temperature, specific heat and latent he...

Nowadays, the most matured thermal energy storage (TES) technology for Concentrated Solar Power (CSP) plants is the use of molten solar salts (60 wt% NaNO3 – 40 wt% KNO3), but the thermal decomposition of nitrate salts can result in changes in the composition of molten salts or potential risks ...

The goal of this study was to determine the effect of intravenous (IV) administration of phosphite on the serum concentration of inorganic phosphorus in cows. Twelve clinically healthy cows were divided into four groups of three. All cows received 600 mL of a 40% calcium borogluconate solution; ...

A novel electroless nickel-phosphorus (NiP) process employing tetrasodium pyrophosphate and ammonium citrate as complexing agents and nickel hypophosphite as the nickel source which avoids the use of SO42− and Cl− ions was developed to improve the anti-corrosion properties of AZ91D magnesium all...

Monovalent alkali halides such as NaI, CsI, and LiI are widely used as inorganic scintillators for radiation detection due to their light yield, the capability for the growth of large single crystals, relatively low cost, and other favorable characteristics. These materials are frequently activa...

The dye sensitized solar cell needs a tremendous improvement to be competitive with other solar cell that are available in the market. To battle this issue a band gap materials engineering needs to be considered. In this study, a numerical model analysis is developed to take into consideration t...

Single crystal of pure Lithium Iodide (LiI) has been grown from melt by using the vertical Bridgman technique. Thermoluminescence (TL) Measurements were carried out at 1 K/s following X-ray irradiation. The TL glow curve consists of a dominant peak at (peak-maximum Tm) 393 K and one low temperat...

The structures of microsolvated (LiI)2−(H2O)n (n = 0–6) clusters and their corresponding neutrals were determined using ab initio calculations. One Li-I distance in (LiI)2−(H2O)n abruptly increases at n = 5, thus a I atom is firstly seperated out from the (LiI)2− unit. For the neutrals, the not...

The paper discusses scintillation and luminescence properties of thallium-doped LiI crystals, grown by the Bridgman technique. X-ray induced emission spectrum is obtained between 380 nm and 600 nm, and is attributed to the Tl+ ion. The photoluminescence measurement with the excitation wavelength...
