In situ growth of chrysanthemum-like NiCoS on MXenes for high-performance supercapacitors and a non-enzymatic HO sensor.

In this work, we developed a novel strategy to couple chrysanthemum-like NiCoSin situ-grown MXene hybrids into a three-dimensional (3D) sandwich architecture hybrid as an electrode material for high-performance asymmetric supercapacitors and non-enzymatic HO sensors. In the 3D sandwich architecture hybrid, the NiCoS particles were encapsulated by MXene layers, which enhanced the interlayer space of MXene, significantly improving the electrochemical properties. In particular, the MXene/NiCoS 1 : 2 electrode achieved a specific capacitance of 1266 F g at 0.

The effects of deposition time and current density on the electrochemical performance of flexible and high-performance MnO@PFG composite electrodes.

A novel composite electrode has been fabricated by the direct deposition of MnO onto graphene networks surrounding a paper fiber (PFG). The paper fiber between graphene sheets could be used as a flexible substrate for MnO nanoparticles, and the microscopic morphologies and electrochemical performances of the MnO@PFG electrodes were tuned regulating the deposition current densities and deposition times. 3D graphene on PFG served as a highly conductive backbone with a high surface area for the deposition of the MnO nanoparticles, which provided high accessibility to electrolyte ions for shortening the diffusion paths.

[The influence of reference data noise on the NIR prediction results].

This article used hemicelluloses content in acacia spp. wood as a case study to demonstrate the influence of noise in the reference data on the results of NIR calibration model. The results indicated that the accuracy of NIR calibration model was affected by the reference data noise.

Genetic polymorphism of glutathione S-transferase T1 gene and susceptibility to idiopathic azoospermia or oligospermia in northwestern China.

Aim: To investigate the association of glutathione S-transferase T1 (GSTT1) gene polymorphism in patients with idiopathic azoospermia or oligospermia in the northwestern China population.

Methods: In the case-control study, GSTT1 genotypes were identified by multiplex polymerase chain reaction (PCR) with peripheral blood DNA samples from 78 patients with idiopathic azoospermia, 103 patients with idiopathic oligospermia and 156 age-matched controls with normal sperm concentration and motility, according to the criteria adapted from World Health Organization guidelines. All of the patients and controls were from northwestern China.

[Genetic polymorphism of glutathione S-transferase T1 associated with idiopathic azoospermia and oligospermia].

Objective: To investigate the association of glutathioneS-transferase T (GSTT1) gene polymorphism with azoospermia and oligospermia.

Methods: Semen samples from 34 patients with idiopathic azoospermia, 40 patients with idiopathic oligospermia and 53 healthy controls with normal sperm concentration and motility were assessed according to the standards of WHO. The GSTT1 genotypes were identified by multiplex polymerase chain reaction (PCR) with peripheral blood DNA samples.
