Improvement of anchor structural unit in FLAC3D and its application to the 110 construction method.

Numerical simulation is an important method for analyzing the behavior of supports under complex geological conditions. FLAC3D, a widely used analysis tool, assumes the anchor structural unit to be an ideal elastoplastic material, which limits its ability to simulate strength decay in situations involving large deformation. In this study, we enhanced the anchor structural unit in FLAC3D software by developing a nonlinear convergent model of the anchor structure.

Effect of Boiling and Roasting Treatments on the Nutrients, Lipid Quality, and Flavor of Peanuts.

Roasted peanuts (OPs) are more often used in daily life than boiled peanuts (BPs); the main reason may be related to the pleasurable flavor in OPs. This study comparatively investigated the effects of boiling and roasting on nutritional components contents, taste, and aroma to reveal the advantages of roasting in terms of the nutrition and flavor of peanuts. Results showed that boiling increased fat content to 54.

Scaling-Free Cathodes: Enabling Electrochemical Extraction of High-Purity Nano-CaCO and -Mg(OH) in Seawater.

For electrochemical application in seawater or brine, continuous scaling on cathodes will form insulation layers, making it nearly impossible to run an electrochemical reaction continuously. Herein, we report our discovery that a cathode consisting of conical nanobundle arrays with hydrophobic surfaces exhibits a unique scaling-free function. The hydrophobic surfaces will be covered with microbubbles created by electrolytic water splitting, which limits scale crystals from standing only on nanotips of conical nanobundles, and the bursting of large bubbles formed by the accumulation of microbubbles will cause a violent disturbance, removing scale crystals automatically from nanotips.

Fine Purification Engineering Enables Efficient Perovskite QLEDs with Efficiency Exceeding 23.

Perovskite quantum dots (PeQDs) have great application prospects in fields such as displays and solar cells due to their adjustable band gap, high absorption coefficient, high carrier mobility, and solution processability. However, the ionic crystal characteristic of PeQDs and their surface ligands have led to problems such as solvent sensitivity, poor crystal stability, and difficulty in adjusting the photoelectric properties, which are challenges in high-quality PeQDs. Here, to solve the problem of fluorescence degradation caused by phase change and loss of surface ligands during the purification process of CsPbI QDs, this work develops a purification strategy that finely regulates the polarity of the purification solvent, to obtain high-purity perovskite.

Possible hazards from biodegradation of soil plastic mulch: Increases in microplastics and CO emissions.

Biodegradable mulches are widely recognized as ecologically friendly substances. However, their degradation percentage upon entering soils may vary based on mulch type and soil microbial activities, raising concerns about potential increases in microplastics (MPs). The effects of using different types of mulch on soil carbon pools and its potential to accelerate their depletion have not yet well understood.

The flavor substances changes in Fuliang green tea during storage monitoring by GC-MS and GC-IMS.

To study the effect of storage (for 0, 3, 6, and 12 months) on the flavor of green tea (GT), we monitored the volatile organic compounds (VOCs) in GT through gas chromatography (GC) combined with ion mobility spectrometry and headspace solid-phase micro extraction, GC-MS (mass spectrometry). Then, relative odor activity value (ROAV) was applied to analyze the aroma contribution of the VOCs. During storage, the polyphenol and caffeine contents gradually decreased from 22.

IgE Recognition and Structural Analysis of Disulfide Bond Rearrangement and Chemical Modifications in Allergen Aggregations in Roasted Peanuts.

Given that roasting changes the structure and allergenicity of peanut allergens, the structural information of peanut allergens must be expounded to explain the alteration in their allergenicity. This work focused on allergen aggregations (AAs) in roasted peanuts. IgE recognition capability was assessed via western blot analysis.

Overcoming Cancer Multi-drug Resistance (MDR): Reasons, mechanisms, nanotherapeutic solutions, and challenges.

Multi-drug resistance (MDR) in cancer cells, either intrinsic or acquired through various mechanisms, significantly hinders the therapeutic efficacy of drugs. Typically, the reduced therapeutic performance of various drugs is predominantly due to the inherent over expression of ATP-binding cassette (ABC) transporter proteins on the cell membrane, resulting in the deprived uptake of drugs, augmenting drug detoxification, and DNA repair. In addition to various physiological abnormalities and extensive blood flow, MDR cancer phenotypes exhibit improved apoptotic threshold and drug efflux efficiency.

High-performance, self-powered flexible MoS photodetectors with asymmetric van der Waals gaps.

With an urgent demand for low-energy-consumption and wearable devices, it is desirable to find an easy, effective, and low-cost method to fabricate self-powered flexible photodetectors with simple configurations and high-performance. Self-powered photodetectors are normally fabricated based on either two different materials or the same material in contact with two different metal electrodes. Here, a flexible MoS photodetector with the same Au electrodes was fabricated on a polyethylene terephthalate (PET) substrate which exhibits self-powered properties.

ML-SA1 and SN-2 inhibit endocytosed viruses through regulating TRPML channel expression and activity.

Transient receptor potential mucolipin 2 and 3 (TRPML2 and TRPML3), as key channels in the endosomal-lysosomal system, are associated with many different cellular processes, including ion release, membrane trafficking and autophagy. In particular, they can also facilitate viral entry into host cells and enhance viral infection. We previously identified that two selective TRPML agonists, ML-SA1 and SN-2, that showed antiviral activities against dengue virus type 2 (DENV2) and Zika virus (ZIKV) in vitro, but their antiviral mechanisms are still elusive.

Biostimulants decreased nitrogen leaching and NH volatilization but increased NO emission from plastic-shed greenhouse vegetable soil.

Biostimulant application is an effective strategy to enhance soil fertility and plant growth. However, its comprehensive impacts on nitrogen (N) uptake and reactive N (Nr) losses via leaching, ammonia (NH) volatilization, and nitrous oxide (NO) emission from plastic-shed greenhouse vegetable system are still little known. Therefore, a field experiment was conducted with cauliflower-tomato growth rotation (from September 6, 2018, to July 17, 2019) receiving three biostimulants, i.

Mechanism of the enhanced coercivity for the dual-main-phase Ce-Fe-B magnet.

The high coercivity of Nd-Fe-B magnets can also be obtained in the Ce-Fe-B magnets fabricated via the dual-main-phase (DMP) method in which the high abundance Ce was used to substitute Nd(Pr). The inhomogeneous distributions of the matrix grains in the DMP magnet play a key role in the enhanced magnetic performance. Compared with the single-phase magnet, more grain boundary phases encapsulating the matrix 2:14:1 grain are formed in the DMP magnet, which reduce the exchange coupling between adjacent magnetic grains.
