TL;DR: In this paper, a thermal annealing of zinc oxide nanoparticles was successfully achieved by using zinc acetate dihydrate (Zn(CH3COO)2·2H2O) precursor with urea (NH2CONH2) for the synthesis of hydrozincite.

TL;DR: In this article, a trifunctional electrocatalyst of ultrafine Pt nanoparticles anchored on CoS2-N-doped reduced graphene oxide (Pt@CoS 2-NrGO) was developed.
Abstract: Constructing more active and durable trifunctional electrocatalysts is key for boosting overall water splitting and metal–air battery efficiency. Herein, we developed a trifunctional electrocatalyst of ultrafine Pt nanoparticles anchored on CoS2-N-doped reduced graphene oxide (Pt@CoS2-NrGO). Owing to its more Pt active sites with rapid ion/electron transport ability, the Pt@CoS2-NrGO shows excellent trifunctional activities towards HER (ƞ10 = 39 mV), OER (ƞ10 = 235 mV) ORR (E1/2 = 0.85 V vs. RHE) and water splitting device of Pt@CoS2-NrGO||Pt@CoS2-NrGO achieved cell voltage of 1.48 V at 10 mA cm−2, which is better than Pt-C||RuO2. Finally, we employed Pt@CoS2-NrGO as air cathode for zinc–air battery to display a power density of 114 mW cm-2 and durability of 55 h, outperforming than Pt-C + RuO2 based zinc–air batteries. For practical aspects, Pt@CoS2-NrGO based zinc–air batteries were connected to overall water splitting device to produce H2 and O2 gases for hydrogen fuel cell.

TL;DR: T cell responses to CII or CII (255-274) were enhanced in RA, especially in early disease, suggesting that CII-reactive T cells play an important role in the pathogenesis of RA.
Abstract: Objective To determine the presence of specific immune recognition of type II collagen (CII) and its immunodominant epitope CII (255–274) in patients with rheumatoid arthritis (RA). Methods T cell proliferative responses to bovine CII and a synthetic peptide encompassing CII (255–274) in peripheral blood mononuclear cells (PBMC) and synovial fluid mononuclear cells (SFMC) from RA patients, and in PBMC from osteoarthritis (OA) patients and healthy controls were assayed by mixed lymphocyte culture. Results The stimulation index (SI) and the number of positive (SI ≥2) T cell responses to CII were higher in RA patients (n = 106) than in OA patients (n = 26) and healthy controls (n = 34). T cell responses to CII (255–274) were also enhanced in RA patients and correlated well with those to CII. In SFMC, positive responses to CII or CII (255–274) were detected in 61.9% of 42 RA patients. T cell responses to CII in SFMC were stronger and more prevalent than peripheral responses. The SI and positive responses to CII were higher in early RA than in late RA. Levels of IgG antibodies to CII in synovial fluid inversely correlated with T cell responses to CII. Conclusion T cell responses to CII or CII (255–274) were enhanced in RA, especially in early disease. Synthetic peptide CII (255–274), as well as native CII, could be recognized as immunogenic antigens by T cells, particularly in the synovial fluid. These observations suggest that CII-reactive T cells play an important role in the pathogenesis of RA. Peripheral tolerance induction using CII (255–274) might be useful in the treatment of RA.

TL;DR: High-aspect-ratio ZnO nanowires based ultra-sensitive hydrazine amperometric sensor has been fabricated which showed a high and reproducible sensitivity and low detection limit and is the first report in which such a very high-sensitivity andLow detection limit has been achieved for the hydrazin sensors by using ZNO nanostructures modified electrodes.
