Hierarchical (Ni,Co)0.85Se Sheets for Efficient Oxygen Evolution Reaction Electrocatalysis: A Combined Approach of Fabrication Control and Mechanistic Understanding We present a fabrication process for hierarchical (Ni,Co)0.85Se sheets, achieving efficient oxygen evolution reaction (OER) activity with a 10 mA cm−2 current density at an overpotential of 290 mV. Porous architecture and doping improve kinetics, supported by DFT calculations.

Between January 2013 and December 2020, 183 patients with mCRC who met the inclusion and exclusion criteria from the Tianjin Medical University Cancer Institute and Hospital were selected. Among them, 143 patients received chemotherapy ± targeted drugs, and the remaining 40 patients were given anti-angiogenic monotherapy. The baseline disease characteristics at the index date of third-line therapy were listed in Table 1.

Until now, controversy still exists on the optimal cut-off values of NLR, PLR and fibrinogen for predicting prognosis in ESCC. In our study, we use the method of c-index to determine the optimal cut-off values of these biomarkers. The results showed that the c-index values were maximum for OS (and/or DFS) when NLR, PLR and fibrinogen were 1.6, 126, and 3.8, respectively (Table S1).

AbstractEvidence for microbial biodegradation of polyethylene terephthalate (PET) has been reported, but little is known about the PET biodegradation process and molecular mechanism by marine microorganisms. Here, we show the biodegradation of PET by the membrane-anchored PET esterase from the marine bacterium Rhodococcus pyridinivorans P23, elucidate the properties of this enzyme, and propose the PET biodegradation by this strain in biofilm.
