The surface of a germanium internal reflectance element (IRE) was modified to bind 6X-histidine (his)-tagged biomolecules. The step-by-step surface modification was monitored via single-pass attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FT-IR). Initially an adlayer of 7-octenyltrimethoxysilane (7-OTMS) was formed on the Ge crystal through the surface hydroxyl groups,...

Major commercial applications of chelators include the pulp and paper, textile, metal, photographic, cosmetic and detergent industry.The substitution of polyphosphates in P-free washing products with complexing agents such as nitrilotriacetic acid (NTA), sodium citrate, sodium carboxymethyltartonate (CMT) and recently co-polymeric carboxylic acids and inorganic builder Zeolite type A enabled th...

A comparative study of ab initio 6-31G(*) and semiempirical modified neglect of differential overlap (MNDO) bond orders and MNDO diatomic energy contributions for the description of bond strengths in neutral and protonated glycine, diglycine, triglycine, and dialanine is presented. Good correlations were found between 6-31G(*) and MNDO bond orders and between MNDO bond orders and diatomic energ...

Quantitative studies of complex formation from the determination of stability constants of the binary complexes of metal (II)/(III)alizarin and also the mixed complexes of metal (II)/(III)alizarin-NTA have been described using paper electrophoretic technique. The stability constant of metal-(II)/(III)-alizarin are found to be 105.14, 104.84, 104.44 and 104.14 and mixed complexes of metal (II)/(...

the aim of this work was to study the ability of two biodegradable chelating agents, nitrilotriaceticacid (nta) and ethylenediiminopropanedioic acid (eddm) to complex metals, in the treatment of the pulp,prior to a totally chlorine free (tcf) bleaching process, and compare with the ethylenediaminetetraacetic acid(edta) performance. firstly, speciation efficiency index (sei) was calculated by co...

CuMnO2 nanoflakes have been prepared utilizing a hydrothermal technique with nitrilotriacetic acid as precipitant. The structure, composition, and morphology are characterized by several techniques. Interestingly, the as-prepared sample delivers 993 mAh g−1 after 300 cycles, excellent rate capabilities (523.2, 293.3, 156.1 at 0.5, 1.0, 2.0 A g−1, respectively) anode of Li-half battery, high spe...

Deinococcus geothermalis is an extremely radiation-resistant thermophilic bacterium closely related to the mesophile Deinococcus radiodurans, which is being engineered for in situ bioremediation of radioactive wastes. We report that D. geothermalis is transformable with plasmids designed for D. radiodurans and have generated a Hg(II)-resistant D. geothermalis strain capable of reducing Hg(II) a...
