Emerging Roles of Nanozymes in Plant and Environmental Sectors.

The demand for food has increased dramatically as the global population increases, putting more strain on the sustainability of agriculture. To fulfill this requirement, it is imperative to develop brand-new technologies. The application potential of nanozymes in the plant and environmental sectors is progressively becoming apparent as a result of their effective enzymatic catalytic activity and the distinctive characteristics of nanomaterials, including size, specific surface area, optical properties, and thermal properties.

A pyroxene-based quantum magnet with multiple magnetization plateaus.

Pyroxenes (AMXO) consisting of infinite one-dimensional edge-sharing MO chains and bridging XO tetrahedra are fertile ground for finding quantum materials. Thus, here, we have studied calcium cobalt germanate (CaCoGeO) and calcium cobalt silicate (CaCoSiO) crystals in depth. Heat capacity data show that the spins in both compounds are dominantly Ising-like, even after being manipulated by high magnetic fields.

TrustEMG-Net: Using Representation-Masking Transformer with U-Net for Surface Electromyography Enhancement.

Surface electromyography (sEMG) is a widely employed bio-signal that captures human muscle activity via electrodes placed on the skin. Several studies have proposed methods to remove sEMG contaminants, as non-invasive measurements render sEMG susceptible to various contaminants. However, these approaches often rely on heuristic-based optimization and are sensitive to the contaminant type.

Development of selective heterocyclic PDE4 inhibitors for treatment of psoriasis.

Psoriasis is a chronic autoimmune disease that badly affects the life quality of patients and their families. Inadequate efficacy, safety risks, high cost and low compliance of current psoriasis drugs urge development of novel small molecular drugs. In this study, two series of 37 novel compounds were designed and synthesized as inhibitors of phosphodiesterase 4 (PDE4) that specifically hydrolyzes second messenger cAMP and is an effective target for treatment of inflammatory diseases.

High-Efficiency Photo-Assisted Large Current-Density Water Splitting with Mott-Schottky Heterojunctions.

The development of bifunctional photogenerated carrier-assisted electrocatalytic (PCA-EC) electrodes that operate with stability at large current-density remains a significant challenge. Herein, we demonstrate a simple sputtering-deposition process to synthesize a novel MnWO/FeCoNi Mott-Schottky heterojunction coating and deposit it on a pure Ti substrate to prepare high-performance PCA-EC electrodes, which exhibits enhanced light absorption range/intensity and rapidly separated photogenerated electron-hole pairs. This design allows photogenerated electrons to directly participate in the hydrogen evolution reaction (HER), while the strong oxidation of photogenerated holes significantly reduces the defect formation energy of active metals, thereby facilitating the rapid reconstruction of highly active Ni(FeCo)OOH/MnOOH species for the oxygen evolution reaction (OER).

HIV-1 M group subtype classification using deep learning approach.

Traditionally, the classification of HIV-1 M group subtypes has depended on statistical methods constrained by sample sizes. Here HIV-1-M-SPBEnv was proposed as the first deep learning-based method for classifying HIV-1 M group subtypes via env gene sequences. This approach overcomes sample size challenges by utilizing artificial molecular evolution techniques to generate a synthetic dataset suitable for machine learning.

Associations of black and sugar-sweetened coffee consumption with depressive symptoms: A longitudinal study of Chinese adolescents.

Background: Previous research revealed an association between coffee consumption and depressive symptoms. However, the results differed between studies in adults and adolescents. Additionally, limited research on coffee and depressive symptoms has distinguished between black and sugar-sweetened coffee.

Construction and validation of a nomogram prediction model for the catheter-related thrombosis risk of central venous access devices in patients with cancer: a prospective machine learning study.

Central venous access devices (CVADs) are integral to cancer treatment. However, catheter-related thrombosis (CRT) poses a considerable risk to patient safety. It interrupts treatment; delays therapy; prolongs hospitalisation; and increases the physical, psychological and financial burden of patients.

Association between community walkability and hypertension: Evidence from the Wuhan Chronic Disease Cohort Study.

While community walkability is recognized as a key environmental factor for health status, evidence linking it specifically to hypertension is rather limited. To fill the knowledge gap, we concluded a cross-sectional study among 6421 eligible participants from the Wuhan Chronic Disease Cohort. A well-developed algorithm was performed to evaluate community walkability across Wuhan, quantified as Walk Score.

Pyrene-based covalent organic frameworks (PyCOFs): a review.

Recently, pyrene-based covalent organic frameworks (PyCOFs) have aroused great interest because the large planar structure of the pyrene unit could effectively enhance the interlayer π-π interaction and promote the separation and migration of carriers, significantly improving the crystallinity and photoelectrical properties of PyCOFs. Since the first PyCOF-containing boroxate linkage was reported in 2008 by the Yaghi group, many PyCOFs with different kinds of linkages have been reported, exhibiting great potential applications in different fields such as adsorption/separation, chemical sensing, catalysis, energy storage, However, as far as we know, the reviews related to PyCOFs are rare, although PyCOFs have been widely reported to show promising applications. Thus, it is right time and important for us to systematically summarize the research advance in PyCOFs, including the synthesis with different linkages and applications.
