Co-pyrolysis of corn stalk and high-density polyethylene with emphasis on the fibrous tissue difference on thermal behavior and kinetics.

The thermal properties of various corn stalk tissues (including stem, husk, ear, cob, and leaf), high-density polyethylene (HDPE), and their blends were investigated using thermogravimetric analysis under a nitrogen atmosphere. The results indicate that the thermal decomposition process of corn stalk tissue/HDPE mixtures is delayed with an increasing heating rate, regardless of the tissue type. Besides, the structural differences among various corn stalk tissues significantly influence their thermal behavior, product distribution, and co-pyrolysis kinetics with HDPE.

Recycling the sediment of cotton spinning effluent for rigid polyurethane foams.

Sediment from the effluent of cotton spinning industry was valorized as the renewable bio-based polyols substitute for the rigid polyurethane (RPUFs), targeting to generate the economic and environmental benefits. Before reaction with the isocyanate, the sediment was functionalized by hydroxymethylation, in order to increase the density of the active hydroxyl groups for higher reactivity. The structural characterization results of the functionalized sediment indicated the material exhibited narrow molecular weight distribution, high hydroxyl groups content, and highly aromatic skeleton, which can be qualified as the renewable polyols for the RPUFs.

Comparative simulations of methanol steam reforming on PdZn alloy using kinetic Monte Carlo and mean-field microkinetic model.

Methanol steam reforming (MSR) is an attractive route for producing clean energy hydrogen. PdZn alloys are extensively studied as potential MSR catalysts for their stability and high CO2 selectivity.

Influence of Hole Transport Layers on Buried Interface in Wide-Bandgap Perovskite Phase Segregation.

Light-induced phase segregation, particularly when incorporating bromine to widen the bandgap, presents significant challenges to the stability and commercialization of perovskite solar cells. This study explores the influence of hole transport layers, specifically poly[bis(4-phenyl)(2,4,6-trimethylphenyl)amine (PTAA) and [4-(3,6-dimethyl-9H-carbazol-9-yl)butyl]phosphonic acid (Me-4PACz), on the dynamics of phase segregation. Through detailed characterization of the buried interface, we demonstrate that Me-4PACz enhances perovskite photostability, surpassing the performance of PTAA.

Rapid fractionation of corn stover by microwave-assisted protic ionic liquid [TEA][HSO] for fermentative acetone-butanol-ethanol production.

Background: The use of ionic liquids (ILs) to fractionate lignocelluloses for various bio-based chemicals productions is in the ascendant. On this basis, the protic ILs consisting of triethylammonium hydrogen sulfate ([TEA][HSO]) possessed great promise due to the low price, low pollution, and high efficiency. In this study, the microwave-assistant [TEA][HSO] fractionation process was established for corn stover fractionation, so as to facilitate the monomeric sugars production and supported the downstream acetone-butanol-ethanol (ABE) fermentation.

Yolk-shell FeS@N-doped carbon nanosphere as superior anode materials for sodium-ion batteries.

Iron sulfides have shown great potential as anode materials for sodium-ion batteries (SIBs) because of their high sodium storage capacity and low cost. Nevertheless, iron sulfides generally exhibit unsatisfied electrochemical performance induced by sluggish electron/ion transfer and severe pulverization upon the sodiation/desodiation process. Herein, we constructed a yolk-shell FeS@NC nanosphere with an N-doped carbon shell and FeS particle core via a simple hydrothermal method, followed by in-situ polymerization and vulcanization.

Interface engineering of metal sulfides-based composites enables high-performance anode materials for sodium-ion batteries.

Metal sulfides (MSs) have attracted much attention as anode materials for sodium-ion batteries (SIBs) due to their high sodium storage capacity. However, the unsatisfactory electrochemical performance induced by the huge volume change and sluggish kinetics hampered the practical application of SIBs. Herein, guided by the heterostructure interface engineering, novel multicomponent metal sulfide-based anodes, including SnS, FeS, and FeN embedded in N-doped carbon nanosheets (SnS/FeS/FeN/NC NSs), have been synthesized for high-performance SIBs.

Patients And Methods: The multicenter data of 838 gastric cancer patients who received neoadjuvant chemotherapy and gastrectomy combined with D2 lymphadenectomy were analyzed retrospectively.

Hyaluronic acid oligosaccharide-modified zeolitic imidazolate framework-8 nanoparticles loaded with oxaliplatin as a targeted drug-delivery system for colorectal cancer therapy.

Exploring a nanoscale targeted drug-delivery system (DDS) for oxaliplatin (Oxa) to improve its therapeutic effect in colorectal cancer. Nanoparticles were prepared using zeolitic imidazole framework-8 (ZIF-8) modified by hyaluronic acid oligosaccharide (oHA) as an Oxa carrier (oHA@ZIF-8@Oxa). After multiple characterizations, the therapeutic efficacy of the DDS was evaluated by cytotoxicity testing and a nude mouse tumor transplantation experiment .

MiR-654-3p targets SRC to suppress tumor growth in non-small cell lung cancer.

Around the world, cancer-related death is primarily caused by lung cancer all the time. MiR-654-3p plays an outstanding role in the development of cancer, but the mechanism of miR-654-3p in non-small cell lung cancer (NSCLC) is uncertain. For this purpose, a quantitative real-time polymerase chain reaction(qRT-PCR) was carried out to detect the expression of miR-654-3p and SRC mRNA.

OsLTP47 may function in a lipid transfer relay essential for pollen wall development in rice.

In plants, lipid transfer proteins (LTPs) transport pollen wall constituents from the tapetum to the exine, a process essential for pollen wall development. However, the functional cooperation of different LTPs in pollen wall development is not well understood. In this study, we have identified and characterized a grass-specific LTP gene, OsLTP47, an important regulator of pollen wall formation in rice (Oryza sativa).

The dry powder inhaler is a new form of drug delivery that is widely used as an alternative to traditional drug delivery methods, addressing the shortcomings of traditional drug delivery methods and obtaining better therapeutic results. This mode of delivery is also one of the most rational ways to treat pulmonary diseases such as chronic obstructive pulmonary disease (COPD). Curcumin, a natural polyphenol, has been shown to be effective in the treatment of COPD.

Novel hyaluronic acid oligosaccharide-loaded and CD44v6-targeting oxaliplatin nanoparticles for the treatment of colorectal cancer.

Oxaliplatin resistance is one of the main causes of failed colorectal cancer treatment, followed by recurrence and metastasis. In this study, we found that colorectal cancer cells secrete a high level of hyaluronic acid (HA), which interacts with its receptor CD44v6 to mediate colorectal cancer resistance to chemotherapy. HA oligosaccharide (oHA) is a degradation product of HA.

Hierarchical Cobalt-Doped Molybdenum-Nickel Nitride Nanowires as Multifunctional Electrocatalysts.

Herein, we demonstrate hierarchically porous Co-doped MoNi nitride nanowires for multifunctional electrocatalysts. After the Co incorporation for water electrolysis and zinc-air systems, the active surface area is enhanced, whereas the charge-transfer and mass-transfer resistances are reduced significantly. Due to the dual modulation in the electric conductivity and active surface area induced by the Co-doping, the hierarchically porous trimetal nitrides show high activity and good stability for the hydrogen evolution reaction, oxygen evolution reaction, and oxygen reduction reaction.

Natural killer cells involved in tumour immune escape of hepatocellular carcinomar.

Natural killer cells are the first line of host immune surveillance and play major roles in the defence against infection and tumours. Hepatic NK cells exhibit unique phenotypic and functional characteristics compared to circulating and spleen NK cells, such as higher levels of cytolytic activity and cytotoxicity mediators against tumour cells. However, the activities of NK cells may be reversed during tumour progression.
