Developing high-capacity and cyclically stable transition metal (TM)-based electrode materials for energy storage devices, such as aqueous ion energy storage systems, is crucial for addressing the growing issue of energy scarcity. The spin state, or spin configuration of the d-electrons, plays a vital role in the electrochemical energy storage performance of these materials. However, there has been a lack of systematic descriptions regarding the role of spin configurations in electrochemical energy storage to date.

The strategic enhancement of manganese-oxygen (Mn─O) covalency is a promising approach to improve the intercalation kinetics of sodium ions (Na⁺) in manganese dioxide (MnO). In this study, an augmenting Mn─O covalency in MnO by strategically incorporating cobalt at oxygen edge-sharing Co octahedral sites is focused on. Both experimental results and density functional theory (DFT) calculations reveal an increased electron polarization from oxygen to manganese, surpassing that directed toward cobalt, thereby facilitating enhanced electron transfer and strengthening covalency.

The pressing demand for large-scale energy storage solutions has propelled the development of advanced battery technologies, among which zinc-ion batteries (ZIBs) are prominent due to their resource abundance, high capacity, and safety in aqueous environments. However, the use of manganese oxide cathodes in ZIBs is challenged by their poor electrical conductivity and structural stability, stemming from the intrinsic properties of MnO and the destabilizing effects of ion intercalation. To overcome these limitations, our research delves into atomic-level engineering, emphasizing quantum spin exchange interactions (QSEI).

Article Synopsis
  • The conversion of formate in alkaline solutions is important for fuel cell technology, but hydrogen adsorption on catalysts has been a challenge for efficiency.
  • A new catalyst strategy using palladium nanoparticles on a phosphorus-doped TiO substrate creates a "push-pull" effect, enhancing hydrogen release and transfer.
  • The improved Pd/TiO-P catalyst shows a mass activity of 4.38 A mg, significantly outperforming the previous Pd/TiO catalyst, indicating a major step forward in catalyst efficiency for fuel cells.

This study addresses the critical challenge in alkaline direct formate fuel cells (DFFCs) of slow formate oxidation reaction (FOR) kinetics as a result of strong hydrogen intermediate (H) adsorption on Pd catalysts. We developed WO-supported Pd nanoparticles (EG-Pd/WO) via an organic reduction method using ethylene glycol (EG), aiming to modulate the d-band center of Pd and alter H adsorption dynamics. Cyclic voltammetry demonstrated significantly improved H desorption kinetics in EG-Pd/WO catalysts.

This study aimed to investigate the effect of a  DPP8 supplementation on the growth performance, pathogenic invasion, inflammation and pathogen resistance signal pathway in rabbits infected with Typhimurium ( Typhimurium). The treatments included a negative control, a positive control with an  Typhimurium infection and a positive control plus DPP8 at 10, 10 or 10 cfu/kg of diet using 300 weaned rabbits. The results showed that supplementing with DPP8 improved ( < 0.

This study aimed to investigate the effect of dietary tetramethylpyrazine (TMP) on the growth performance, nutrient digestion, blood parameters and immunity of broilers under oxidative stress. Five treatments included negative control, positive control with lipopolysaccharide induction and TMP addition at 50, 100 and 150 mg/kg of diet using 600 male Arbor Acres broiler chicks. Results showed that during 1-14 days of age, body weight gain and feed efficiency in the positive control were worsened (p < .

Tetramethylpyrazine (TMP), an alkaloid rich in and fermented products, possesses multiple pharmacological activities in antioxidant, anti-inflammatory, and antibacterial. This study aimed to investigate the effect of TMP (15 mg/L) on the physicochemical and gelation properties of rabbit myofibrillar proteins (MPs) with/without oxidative stress. Results showed that compared to the control, oxidative stress to MPs decreased free thiol content, gel yield, whiteness, water-holding capacity, bounder water, immobilized water, and endogenous tryptophan fluorescence intensity, but increased surface hydrophobicity, dityrosine content, and free water content (p<0.

This study aimed to investigate the effect of dietary cysteamine hydrochloride (CSH) on the growth performance, oxidation, inflammation, and gene expression of cytoskeleton and tight junction in the intestinal mucosa of broiler chickens challenged with Clostridium perfringens (C. perfringens). A total of 360 one-day-old broiler chicks were randomly distributed into 5 groups for a negative control (NC, without C.
