Photosynthetic inorganic biohybrid systems (PBSs) combining an photosensitizer with intact living cells provide innovative view for solar hydrogen production. However, typical whole-cell often suffer from sluggish electron transfer kinetics during transmembrane diffusion, which severely limits the efficiency of Here, a unique system quantum yield 8.42% was constructed by feeding bismuth-doped carbon dots (Bi@CDS) to Escherichia coli (E. coli). In this system, Bi@CDS can enter and electrons...
Abstract Overcoming hypoxia is an urgent clinical challenge in acute kidney injury (AKI) treatment. Specifically, upregulates xanthine oxidase (XO) expression and induces reactive oxygen species (ROS) generation, which exacerbates renal injury. Herein, a therapeutic strategy of self‐supply for highly efficient AKI therapy developed, the biocompatible CeO 2 nanorods modified by poly(ethylene glycol)‐folic acid conjugate (CeFA) catalytically convert ROS into effectively relieve injured...
We use the elementary and analytic methods properties of Chebyshev polynomials to study computational problem reciprocal sums one‐kind give several interesting identities for them. At same time, we also a general method this kind sums.
In this paper, we give some interesting identities and asymptotic formulas for one kind of counting function, by studying the computational problems involving symmetry sums quadratic residues non-residues mod p . The main methods used are properties Legendre’s symbol , estimate character sums. As application, solve two open proposed Zhiwei Sun.

The main purpose of this paper is using the combinatorial method, properties power series and characteristic roots to study computational problem symmetric sums a certain second-order linear recurrence sequences, obtain some new interesting identities. These results not only improve on existing results, but are also simpler more beautiful. Of course, these identities profoundly reveal regularity recursive sequence, which can greatly facilitate calculation sequences in practice.
The ECL behaviors of NaBiF 4 : Yb 3+ /Er UCNPs synthesized via a fast and environment-friendly method are reported for the first time. UCNPs-based biosensor shows wide detection range with low limit 138 CFU mL −1 E. coli O157 H7.
In this paper, the failure mechanism and phase transformation process of 304 stainless steel during erosion wear were studied with a rotary test device. The surface morphologies worn investigated by scanning electron microscopy (SEM). metallographic structures nonworn analyzed optical microscope (OM) transmission (TEM). addition, hardness on different areas sample was also measured. results demonstrated that cutting spalling caused plastic deformation. high-density dislocations move along...
