In flotation, it is very difficult to separate scheelite from calcite. In this study, sodium fluorosilicate (SFS) was used as a depressant in the flotation separation of scheelite from calcite. The selective depression effect of the SFS on calcite was proven by corresponding experiments, such as...

Equilibrium association constants have been calculated for various platinum (II) and platinum (IV) complexes.The association constants were greatest for the dinegatively charged state, regardless of the valence state of the platinum, and the constant decreased considerably as the charge increase...

SummaryThe effects of cis dichlorodiammine platinum [cis Pt(II)], trans dichlorodiammine platinum (trans Pt(II)],cis tetrachlorodiammine platinum [cis Pt(IV)], trans tetrachlorodiammine platinum [trans Pt(IV)], and ethylenediaminedichloride platinum [Pt(II)en] on the absorption spectra, and ther...

A factorial design is applied to the optimization of the determination of dimethyltin chloride by hydride generation gas phase molecular absorption spectrometry (HG-GPMAS). A method is described for the determination of dimethyltin chloride after conversion into gaseous dimethyltin hydride by ad...

Dimethyltin dihalides Me2SnX2 (X = Cl, Br) only form 1:1 complexes with 2,6-dimethoxyphenylphosphine oxides Φ3PO, PhΦ2PO and Ph2ΦPO (Φ = 2,6-(MeO)2C6H3) even though the ligands are used in excess. 2,6-Dimethoxyphenylphosphine sulphides Φ3PS and PhΦ2PS also form analogous 1:1 comp...

The reaction of dimethyltin dichloride with 1,5-bis(2′-pyridyl)pentane-1,3,5-trione (Htrione) resulted in the formation of the dinuclear complex {[Me2ClSn(μ-trione)SnMe2Cl2]·Htrione} (1) in the solid state. The solid state X-ray determination of the complex {[Me2ClSn(μ-trione)SnMe2Cl2]·Htri...

Reaction between trimeric dimethyltin sulfide and 1,2-dibromoethane of 140°C results in a complex of dimethyltin dibromide with 1,4-dithiane formulated as: Me2SnBr2 · SC2H4C2H4S · Me2SnBr2. X-ray analysis of the crystal structure of this complex has been performed.

The response of muskmelon mesophyll and suspension cells to roridin E, a phytotoxin produced by the fungal pathogen Myrothecium roridum, was monitored by measuring changes in the fluorescence of cells stained with merocyanine 540, an optical probe for changes in transmenbrane electrical potentia...

The widespread use of synthetic nematicides has caused significant problems to the environment as well as human health. To address this issue, eco-friendly control measures, such as microbial nematicides, are being developed. During the screening of Myrothecium strains with nematicidal activity ...

Measurements of thermophysical properties (vapour pressure, density, and viscosity) of the (water + lithium bromide + potassium acetate) system LiBr:CH3COOK = 2:1 by mass ratio and the (water + lithium bromide + sodium lactate) system LiBr:CH3CH(OH)COONa = 2:1 by mass ratio were measured. The sy...

BackgroundThis study was done to compare the accuracy of the Lactate Pro LT 1710 (Arkray Inc., Kyoto, Japan) with the Combiline Plus (Eschweiler GmbH & Co. KG Holzkoppelweg, Kiel, Germany), and also, to analyze the prognostic significance of serum lactates and Simplified Acute Physiology Score 3...

ObjectivesDeviation from manufacturers’ pre-analytical sample handling recommendations necessitates extensive validation studies. This report uses plasma lactate testing, where a recommended 15 min room temperature sample handling limit cannot be met by the clinical laboratory, as an example fo...

Polycrystalline d-lactic acid lithium salt [(R)-2-hydroxypropanoic acid lithium salt, lithium d-lactate] has been investigated by pulsed proton magnetic resonance methods between 77 and 300 K at 25 MHz. The main relaxation mechanism is methyl rotation; the motion is characterized by an activatio...

In this paper, a new 2D lactate electrochemical biosensor was developed. It was based on the incorporation of molybdenum disulfide (MoS2) nanosheets, obtained by an exfoliation method, onto the surface of a glassy carbon (GC) electrode, together with lactate oxidase enzyme (LOx). For the sensor ...

ObjectivesSynovial fluid leukocyte count is the current standard test for diagnosing periprosthetic joint infection (PJI). As D-lactate is almost exclusively produced by bacteria, it represents a useful biomarker for bacterial infection. We evaluated the performance of synovial fluid D-lactate f...

IntroductionLactate could serve as an energy source and signaling molecule in the brain, although there is insufficient in vivo evidence to support this possibility. Here we aimed to use a one-pot enzymatic synthetic procedure to synthesize l-[3-11C]lactate that can be used to evaluate chemical ...

Generalized seizures trigger excessive neuronal firing that imposes large demands on the brain glucose/lactate availability and utilization, which synchronization requires an integral mitochondrial oxidative capability. We investigated whether a single convulsive crisis affects brain glucose/lac...

Herein we report the use of scanning electrochemical microscopy (SECM) together with electrochemical and spectroscopic techniques to develop and characterise a stable and uniformly reactive chemically modified platinum electrode for NADH electrocatalysis. In order to achieve this, a range of dif...

The feasibility of lithium lactate (Li-lactate: CH3CH(OH)COOLi) as an electron spin resonance (ESR) dosimeter material has been studied and compared with lactose and a conventional alanine dosimeter. The ESR spectra of Li-lactate and lactose with the spectroscopic splitting g-factors of 2.0029 ±...
