Catalysis of collagen degradation by matrix metalloproteinase 1 (MMP-1) has been proposed to critically rely on flexibility between the catalytic (CAT) and hemopexin-like (HPX) domains. A rigorous assessment of the most readily accessed conformations in solution is required to explain the onset of substrate recognition and collagenolysis. The present study utilized paramagnetic NMR spectroscopy...

Autologous chondrocyte implantation is the current gold standard cell therapy for cartilage lesions. However, in some instances, the heavily compromised health of the patient can either impair or limit the recovery of the autologous chondrocytes and a satisfactory outcome of the implant. Allogeneic human articular chondrocytes (hAC) could be a good alternative, but the possible immunological in...

The interaction of TiOx with SiO2/Mo(112) has been studied using high-resolution electron energy loss spectroscopy, Auger electron spectroscopy, low-energy electron diffraction, and molecular adsorption. Ti at varying coverages was deposited onto a SiO2/Mo(112) surface followed by oxidation at 600K and annealing at various temperatures. TiOx disperses and covers the SiO2 surface after oxidation...

The chemical degradation of alloy components in sulfur-containing environments is a major concern in oil and gas production. This paper discusses the effect of elemental sulfur and its simplest anion, sulfide, on the corrosion of Cr-Mo alloy steel at pH 2 and 5 during 10, 20 and 30 h immersion in two different solutions. 4130 Cr-Mo alloy steel is widely used as tubing and tubular components in ...

In this paper, we introduce a new class of contact pseudo framed (CPF)-manifolds M,g,f,λ,ξ by real tensor field id="M2">f type id="M3">1...

In this paper, RF MEMS switch with capacitive contact is designed and analyzed for Ka band application. A fixed-fixed beam/meander configuration has been used to design the frequency 10 GHz 40 GHz. Electromagnetic electromechanical analysis of three-dimensional (3D) structure/design in multiple finite element method (FEM) based full-wave simulator (Coventorware high-frequency structure simulato...

The hexaethylcyclohexaarsoxane complexes [{M(CO)3}2{c>’c/o-(C2H 5A sO)6}], M = Cr, Mo, W, 2 4 have been prepared by the reaction o f (C2H 5AsO)n with the respective metal hexacarbonyl in toluene and characterized by their IR and NM R spectroscopic data. For 2 the molec­ ular structure was established by X-ray structural analysis. The 12 atoms o f the As60 6 ring form a flattened cuboctahedron i...

We investigated curvature-enhanced spin-orbit coupling (SOC) and spinterface effect in carbon-based organic spin valves (OSVs) using buckyball C60 and C70 molecules. Since the naturally abundant (12)C has spinless nuclear, the materials have negligible hyperfine interaction (HFI) and the same intrinsic SOC, but different curvature SOC due to their distinct curvatures. We fitted the thickness de...

For overall water-splitting systems, it is essential to establish O2 -insensitive cathodes that allow cogeneration of H2 and O2 . An acid-tolerant electrocatalyst is described, which employs a Mo-coating on a metal surface to achieve selective H2 evolution in the presence of O2 . In operando X-ray absorption spectroscopy identified reduced Pt covered with an amorphous molybdenum oxyhydroxide hy...
