Direct Electroreduction of Low-Concentration CO: Progress and Perspective.

The conversion of CO into carbon-based fuels and chemicals via the electrocatalytic CO reduction reaction (CORR) offers an attractive route to reducing the CO emission for carbon neutrality. Currently, high-purity CO gas has been widely used as the feedstock for most of the CORR studies, while CO sources with a typically low concentration impose the extra cost for CO capture and purification steps. The direct utilization of low-concentration CO for the CORR is a promising approach to substantially address this problem.

[Research on multi-scale convolutional neural network hand muscle strength prediction model improved based on convolutional attention module].

In order to realize the quantitative assessment of muscle strength in hand function rehabilitation and then formulate scientific and effective rehabilitation training strategies, this paper constructs a multi-scale convolutional neural network (MSCNN) - convolutional block attention module (CBAM) - bidirectional long short-term memory network (BiLSTM) muscle strength prediction model to fully explore the spatial and temporal features of the data and simultaneously suppress useless features, and finally achieve the improvement of the accuracy of the muscle strength prediction model. To verify the effectiveness of the model proposed in this paper, the model in this paper is compared with traditional models such as support vector machine (SVM), random forest (RF), convolutional neural network (CNN), CNN - squeeze excitation network (SENet), MSCNN-CBAM and MSCNN-BiLSTM, and the effect of muscle strength prediction by each model is investigated when the hand force application changes from 40% of the maximum voluntary contraction force (MVC) to 60% of the MVC. The research results show that as the hand force application increases, the effect of the muscle strength prediction model becomes worse.

Tailoring Lewis Acidity of Metal Oxides on Nickel to Boost Electrocatalytic Hydrogen Evolution in Neutral Electrolyte.

Neutral-pH water splitting for hydrogen production features a benign environment that could alleviate catalyst and electrolyzer corrosion but calls for the corresponding high-efficiency and earth-abundant hydrogen evolution reaction (HER) catalysts. Herein, we first designed a series of metal oxides decorated on Ni as the model catalysts and found a volcano-shaped relationship between the Lewis acidity of Ni/metal oxides and HER activity in neutral media. The Ni/ZnO with the optimum Lewis acidity could balance water dissociation and hydroxyl desorption, thereby greatly boosting the HER.

Economic renovation of a hillside drip irrigation system using drip tape inlet pressure regulators under computer-aided design.

In hilly areas, significant elevation changes necessitate the use of expensive pressure compensating drip tape to ensure safety and irrigation uniformity, which is economically unfeasible for developing countries. This article proposes a more cost-effective alternative: the use of inexpensive nonpressure compensating drip tape with a pressure regulator (PRL) installed at the inlet. Based on this approach, a low-cost modification of a hilly drip irrigation system with a maximum height difference of 53 m was achieved.

Within this context, non-thermal plasma generated within bubble column reactors emerges as a promising antifungal strategy. The effects of direct plasma bubbles within different discharge modes and thus-produced plasma activated water (PAW) on the inactivation of Saccharomyces cerevisiae are investigated.

Boosting the durability of RuO via confinement effect for proton exchange membrane water electrolyzer.

Ruthenium dioxide has attracted extensive attention as a promising catalyst for oxygen evolution reaction in acid. However, the over-oxidation of RuO into soluble HRuO species results in a poor durability, which hinders the practical application of RuO in proton exchange membrane water electrolysis. Here, we report a confinement strategy by enriching a high local concentration of in-situ formed HRuO species, which can effectively suppress the RuO degradation by shifting the redox equilibrium away from the RuO over-oxidation, greatly boosting its durability during acidic oxygen evolution.

Atg2 controls Drosophila hematopoiesis through the PVR/TOR signaling pathways.

The hematopoietic system of Drosophila is a well-established genetic model for studying hematopoiesis mechanisms, which are strictly regulated by multiple signaling pathways. Autophagy-related 2 (Atg2) protein is involved in autophagosome formation through its lipid transfer function; however, other functions in animal development, especially the role of Atg2 in maintaining hematopoietic homeostasis, are unclear. Here, we show that Atg2 knockdown in the cortical zone (CZ) induced the proliferation and differentiation of mature plasmatocytes and disrupted progenitor maintenance in the medullary zone (MZ).

The mechanism exhibits distinct morphological characteristics compared to apoptosis, autophagy, and necrosis. A notable aspect of ferroptosis is its ability to inhibit uncontrolled tumor replication and immortalization, especially in malignant, drug-resistant, and metastatic tumors.

Insect herbivory on woody broadleaf seedlings along a subtropical elevational gradient supports the resource concentration hypothesis.

Premise: Theories of plant-herbivore interactions hold that seedlings are more vulnerable to herbivory in warmer and more stable climates at lower elevations. Hypotheses of plant apparency, resource concentration, and resource availability have been proposed to explain variability in leaf herbivory. However, seasonal differences in the effects of these hypotheses on leaf herbivory on seedlings remain unclear.
