The high crystallinity (30 %-50 %) of discarded polyester textile waste limits the industrialization of its clean enzymatic depolymerization. In this study, a simple process based on ball milling pretreatment was developed to achieve effective enzymatic hydrolysis of high-crystalline polyester fiber. Ball milling was selected for its short, mild, and chemical-free process, which achieved a remarkable 23.

This study aims to explore the effects of Triptolide (TP) on the differentiation of Th17 cells in ankylosing spondylitis (AS). Peripheral blood mononuclear cells (PBMCs) collected from 10 patients with active AS patients were exposed to TP, GSK-J4 or vehicle. T lymphocyte subsets were analyzed using flow cytometry.

However, there is no systematic identification and functional analysis of JAZ gene family members in sugarcane. In this study, a total of 49 SsJAZ genes were identified from the wild sugarcane species Saccharum spontaneum genome that were unevenly distributed on 13 chromosomes.

However, as a critical aspect of the adverse impacts, little is known about the plastisphere that forms in these engineered environments. Using high-throughput absolute quantification sequencing, we conducted a systemic study combining field survey and laboratory batch test to explain the general plastisphere pattern and the role of environmental and polymeric factors in driving plastisphere succession and assembly there.

However, the efficiency of such a system is limited because of the restriction imposed by the acquisition system. Herein, we propose a phase compensation method that reduces the interferometric fringe period of femtosecond-laser-based CSI, resulting in larger sampling intervals.

We conducted an exome-wide investigation to search for dysregulated RNA editing that drive iCCA pathogenesis.
Methods: An integrative whole-exome and transcriptome sequencing analysis was performed to elucidate the RNA editing landscape in iCCAs.
Real-time measurement of the thickness and group refractive index is crucial for semiconductor devices. In this paper, we proposed a fast synchronous method for measuring the thickness and group refractive index distribution of solid plates based on line-field dispersive interferometry. The proposed method measured the line-field distribution in an illuminated region through a single step.

The structure of the lignin in solution is still poorly understood due to structural variability of isolated lignins. Here, lignins were extracted from different plants to establish a general pattern of their structure in several lignin solvents.

Conventional approaches are subject to restrictions of mechanical instability and measurement speed. The complex locking scheme of previous dual-comb spectroscopic ellipsometry belies its practicability.

Cellulose solubility in the ILs is strongly inhibited by water, which has negative impacts on IL pretreatment and reuse of the recycled ILs. Here, a distillation and aeration apparatus was used as the reactor for biomass pretreatment in dilute aqueous IL solutions and in recycled IL liquor without drying or purification.

Processes that can convert lignocellulosic biomass into biofuels and chemicals are particularly attractive considering renewability and minimal environmental impact. Ionic liquids (ILs) have been used as novel solvents in the process development in that they can effectively deconstruct recalcitrant lignocellulosic biomass for high sugar yield and lignin recovery. From cellulose-dissolving ILs to choline-based and protic acidic ILs, extensive research in this field has been done, driven by the promising future of IL pretreatment.

Based on low-temperature nitrogen adsorption experiments, the FHH (Frenkel-Halsey-Hill) model was employed to investigate the relationship between the marine shale composition, such as TOC, mineral content and shale gas content, and pore structure parameters, such as BET specific surface area, average pore diameter, porosity and fractal dimension. The results show that the pore size distribution curve of shale slowly decreased after the pore size was greater than 50 nm, the pore size distribution showed multiple peaks, and the peak value was mainly in the range of 2-10 nm.

Recently, numerous studies have shown that the OER reaction kinetics can be modified by optimizing components, introducing carbon matrix, and regulating porous nanostructures. Herein, a flexible and controllable electrospinning strategy is proposed to construct porous nitrogen (N)-doped carbon (C) nanofibers (NFs) with nickel-iron (NiFe) alloy nanoparticles encapsulated inside (NiFe@NCNFs) as an OER electrocatalyst.

By analyzing the electrical spectra of the electrical signals generated by the PD, distance and the magnitude and direction of velocity can be derived simultaneously, which is significant for real-time radar applications.
