Summary: In this study, cuprous oxide and carbon coated silicon monoxide (SiOx/C/Cu2O) composites were synthesized by high temperature heat treatment. The carbon acts as a buffer for the volume expansion during lithium intercalation, enhances the material's conductivity, and reduces the contact between the electrolyte and the active substance. Cu2O further reduces the contact between the electrolyte and the active substance, buffering the change of electrode structure and improving the overall cycling performance.

Summary: The silicon suboxide (SiO) anode material shows promise for Lithium-ion batteries (LIBs) due to its high theoretical capacity, but it faces challenges such as large volume change (200%), low electrical conductivity, and low first Coulombic efficiency. A ternary composite ((SiOx/G/SnO2)@C) with a carbon coating layer is developed to address these issues, where graphite as part of the active materials improves Coulombic efficiency and controls volume change, and the carbon coating layer is designed to further restrain the high-volume change of SiOx. With the presence of SnO2, the composite exhibits improved electrochemical performance. Experimental results show that (SiOx/G/SnO2)@C achieves a first charging capacity of 382.6 mAh g(-1) at a current density of 100 mA g(-1), with the Coulombic efficiency improved from 62.2% to 74.9%. After 110 cycles, the capacity reaches 424.6 mAh g(-1) and the capacity retention rate is 103.9%.

Summary: To improve the initial coulombic efficiency and prelithiation efficiency in the prelithiation method using metal lithium, we propose a solid electrochemical corrosion (SEC) of lithium using solid electrolyte LiPON instead of liquid electrolyte. However, the low prelithiation rate of SEC with LiPON interlayer hinders its large-scale application. By introducing an ultrathin film of Bi2O3 as an interface layer, we successfully improve the prelithiation rate of SEC and demonstrate its effectiveness in enhancing the capacity and cycling performance of lithium-ion batteries.

Summary: Overproduction of reactive oxygen species (ROS) during the transition from late gestation to successful lactation in ruminants can lead to oxidative stress (OS), compromising the immune and anti-inflammatory systems and predisposing them to health issues. Metabolic stress during the periparturient period, along with excessive lipolysis, causes immune suppression, abnormal regulation of inflammation, and enhanced oxidative stress. Oxidative stress plays a crucial role in regulating organ metabolism and animal productivity.

Summary: The study investigates the impacts of bedding planes on multiple hydraulic fracturing in unconventional shale reservoirs. Numerical simulations show that bedding planes reduce the non-uniform growth of multiple fractures and prevent hydraulic fractures from passing through the formation with smaller stress contrast. The key problem in hydraulic fracturing in formations containing bedding planes is how to reduce the obstructive effects to increase the length of the main fractures.

Summary: Researchers developed an accurate and fast method for detecting the early internal short circuit (ISC) of Lithium-ion batteries by combining electrochemical impedance spectroscopy (EIS) with a deep neural network (DNN). The ISC detection accuracy reached 97.5% for the normal battery with zero false positives, and the proposed method was also proven to be applicable to other batteries. By selecting the most sensitive EIS spectrum to ISC based on the distribution of relaxation times and sensitivity methods, the required EIS measurement time was further reduced and computational efficiency was improved. The results demonstrate the value of EIS spectrum in battery management systems.

Summary: Unsupervised domain adaptation is important for knowledge transfer in fault diagnosis, but it relies on a clean source domain and a common label set across domains. However, the lack of knowledge on the label set and the presence of unknown classes in the target domain make UDA inapplicable and often impractical. In addition, incorrect annotations are common in industrial dataset curations, but they are largely overlooked in UDA. To address these issues, a Meta Bi-classifier Gradient Discrepancy (MBGD) method is proposed, which incorporates a reliable sample selection approach, a coupled divergence criterion, and a bi-classifier gradient discrepancy for domain adaptation.

Summary: The authors used meter-scale oil shale as the experimental object to study the in situ heating technology for mining oil shale through steam injection. The results showed that hydraulic fracturing started at a pressure 0.34 times lower than the in situ stress, while high-temperature steam fracturing required a pressure 1.2 times higher than the in situ stress. The study also found that horizontal cracks were more easily formed in layered rock masses and that the thermal stress had a stronger influence on the fracture-inducing stress of the orebody.

Summary: Rational design of PGM-free catalysts with well-defined structure is crucial for replacing conventional PGM-based catalysts in the oxygen reduction reaction (ORR), but remains challenging. This study proposes a facile modulation strategy based on solvent effect to tailor nitrogen dopants in MOFs-derived Co-N-C catalysts. DFT calculations suggest that the synergy of pyridinic-N and CoNx significantly enhances the ORR. The optimized Co-N-C catalyst exhibits superior onset potential (Eonset) of 0.915 V and half-wave potential (E1/2) of 0.785 V. This work may pave the way for precise construction of active moieties in large-scale preparation of PGM-free ORR catalysts.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

Summary: By coupling electrochemical testing to operando synchrotron based X-ray absorption and powder diffraction experiments, blended positive electrodes consisting of LiMn2O4 spinel (LMO) and layered LiNi0.5Mn0.3Co0.2O2 (NMC) were studied to understand their redox mechanism. It was found that blending NMC with LMO can enhance energy density at high rates, with the blend containing 25% LMO showing the best performance. Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
