Downsizing the Pt particle to the atomic level in the electro-catalysts is highly desirable to enhance its utilization efficiency in fuel cells. In this study, Pt subnano/nanoclusters were stabilized by the pristine graphene nanosheets (GNSs) derived from chemical vapor deposition and the resulting Pt/GNS hybrids were examined as catalysts for electro-oxidation of alcohols (methanol, ethanol, e...

In rheumatoid arthritis (RA), immunological triggers at mucosal sites, such as the gut microbiota, may promote autoimmunity that affects joints. Here, we used discovery-based proteomics to detect HLA-DR-presented peptides in synovia or peripheral blood mononuclear cells and identified 2 autoantigens, N-acetylglucosamine-6-sulfatase (GNS) and filamin A (FLNA), as targets of T and B cell response...

It is shown how to introduce a geometric description of the algebraic approach to the non-relativistic quantum mechanics. It turns out that the GNS representation provides not only symplectic but also Hermitian realization of a ‘quantum Poisson algebra’. We discuss alternative Hamiltonian structures emerging out of different GNS representations which provide a natural setting for quantum bi-Ham...

The paper summarizes the results of experimental and clinical studies showing a reduced function of the glutamatergic neurotransmitter system (GNS) in the development of critical states of the organism. Reduced function of GNS is considered as an unfavorable prognostic factor associated with key mechanisms of thanatogenesis. (Int J Biomed. 2017;7(1):15-23.)

Sixty Pseudomonas aeruginosa isolates were tested by the agar disk diffusion, AMS Vitek GNS-V flex panel (Vitek Systems, Inc., Hazelwood, Mo.), and agar dilution methods. Although the results of aminoglycoside tests were satisfactory, those of piperacillin and cefoperazone by Vitek GNS-V (T2.05 program) were not acceptable.

Direct formic acid fuel cells (DFAFCs) are one of the most promising power sources due to its high conversion efficiency; relatively low carbon emissions, toxicity, and flammability; convenience; low-cost storage transportation. However, key challenge large-scale commercial applications is poor performance catalyst’s preparation cost. In this study, a new sandwich-structured Pd/polypyrrole-grap...

In this article, the author studies the regularity of 3D generalized Navier-Stokes (GNS) equations with fractional dissipative terms (−∆)αu. It is proved that if div(u/|u|) ∈ Lp(0, T ;Lq(R3)) with 2α p + 3 q ≤ 2α− 3 2 , 6 4α− 3 < q ≤ ∞. then any smooth on GNS in [0, T ) remains smooth on [0, T ].

Motivated by deformation quantization we investigate the algebraic GNS construction of ∗representations of deformed ∗-algebras over ordered rings and compute their classical limit. The question if a GNS representation can be deformed leads to the deformation of positive linear functionals. Various physical examples from deformation quantization like the Bargmann-Fock and the Schrödinger represe...

We have used resonant Raman scattering spectroscopy to fully analyze the relative abundances of different (n,m) species in single-walled carbon nanotube samples that are metallically enriched by density gradient ultracentrifugation. Strikingly, the data clearly show that our density gradient ultracentrifugation process enriches the metallic fractions in armchair and near-armchair species. We ob...

Recently, environment-friendly synthesis of gold nanoparticles (GNPs) has been extensively explored by biologists and chemists. However, significant research is still required to determine whether "eco-friendly" GNPs are beneficial to human health and to elucidate the molecular mechanisms of their effects on human cells. We used human neuronal SH-SY5Y cells to show that treatment with Kalopanac...
