Effect of oxalic acid treatment on the oxidation efficiency of maize stover cellulose and controllable preparation of nanocellulose.

Corn stover was used as raw material, and purification, oxalic acid treatment, oxidation treatment, and ultrasonic treatment were performed to realize the preparation of corn stover nanocellulose with low energy consumption. The effects of oxalic acid concentration (1 wt%, 2 wt%, 3 wt%, 4 wt%, and 5 wt%) on the purity, morphology, crystalline structure and oxidation efficiency of corn stover cellulose during oxalic acid treatment were investigated. The controllable preparation of corn stover nanocellulose was achieved by changing the parameter conditions of ultrasonic treatment.

Integrative Analysis of Liver Metabolomics and Transcriptomics Reveals Oxidative Stress in Piglets with Intrauterine Growth Restriction.

The correlation between oxidative stress and liver metabolic dysfunction in piglets with intrauterine growth restriction (IUGR) remains limited. Therefore, the objective of the present study was to investigate potential mechanisms of metabolic characteristics induced by oxidative stress in the livers of IUGR piglets using metabolomic and transcriptomic analysis. Analysis of the phenotypic characteristics showed that the liver weight of the intrauterine growth restriction piglets was significantly lower than that of normal birth weight piglets.

Preliminary Study on a Biocompatible Cellulose Waterborne Polyurethane Composite Membrane.

A promising technique for repairing necrotic mucosa of human organs has emerged, in which composite films are used to replace human mucosa. In this work, neutral alpha-amylase corrosion solution with a concentration of 0.40 mg/mL and hydrochloric acid corrosion solution at pH 0.

Development and characterizations of a miniature capillary electrophoresis mass spectrometry system.

A miniature capillary electrophoresis mass spectrometry (CE/MS) system has been developed in this work. A 100% electrical driven miniaturized CE device was integrated with a miniature MS instrument, which has a discontinuous atmospheric pressure interface (DAPI) for coupling with atmospheric pressure ionization sources. A nanoelectrospray ionization (nano-ESI) source was developed with a sheath liquid interface for coupling the miniature CE and the MS system.
