To solve large volume change and low conductivity of BiS-based anodes, a coordination regulation strategy is proposed to prepare BiS nanoparticles dispersed in carbon fiber (BiS@CNF) composites. It has been discovered that introducing trimesic acid as a ligand can significantly improve the loading and dispersion of Bi in polyacrylonitrile fibers. The results exhibit that BiS nanoparticles of 200-300 nm are uniformly anchored on the superficial surface layer of CNFs, and BiS nanoparticles of about 20 nm are evenly dispersed in the interior of CNFs.

State-of-the-art optical cavities are pivotal in pushing the envelope of laser frequency stability below 10-16. This is often achieved by extending the cavity length or cooling the system to cryogenic temperatures to reduce the thermal noise floor. In our study, we present a 30-cm-long cavity that operates at room temperature and is outfitted with crystalline coatings.

Galactinol synthase (GolS) genes play important roles in plant response to abiotic stress. In this research, the plant expression vector of soybean - gene was constructed and transformed into tobacco to study the drought tolerance of transgenic tobacco. A - gene with 975 bp coding sequence was cloned from soybean leaves by reverse transcription-polymerase chain reaction (RT-PCR).

According to different nursing schemes, they were divided into 60 cases in the experimental group (ERAS nursing program) and 60 cases in the control group (traditional perioperative nursing). All patients underwent postoperative ultrasonography, and the intraoperative and postoperative rehabilitation indexes of the two groups were analyzed.

A total of 100 patients who were diagnosed with colon cancer after enteroscopy and performed laparoscopic radical surgery were chosen as the research objects. They were divided into an observation group (comprehensive nursing in operation room) and a control group (routine nursing), each of which included 50 cases.

Objective: To study the effects of DCC gene transfection on cell-growth and chemosensitivity of ovarian epithelial carcinoma cell line HO8910.
Methods: Recombinant eukaryotic expression vector pcDNA3.1(+)-DCC containing DCC gene was introduced by lipofectamine transfection reagent into ovarian epithelial carcinoma cell line HO8910 which does not express DCC endogenously.
