Encapsulation Engineering of Sulfur into Magnesium Oxide for High Energy Density Li-S Batteries.

This study addresses the persistent challenge of polysulfide dissolution in lithium-sulfur (Li-S) batteries by introducing magnesium oxide (MgO) nanoparticles as a novel additive. MgO was integrated with sulfur using a scalable process involving solid-state melt diffusion treatment followed by planetary ball milling. XRD measurements confirmed that sulfur (S) retains its orthorhombic crystalline structure (space group Fddd) following the MgO incorporation, with minimal peak shifts indicating slight lattice distortion, while the increased peak intensity suggests enhanced crystallinity due to MgO acting as a nucleation site.

Unveiling BaTiO-SrTiO as Anodes for Highly Efficient and Stable Lithium-Ion Batteries.

Amidst the swift expansion of the electric vehicle industry, the imperative for alternative battery technologies that balance economic feasibility with sustainability has reached unprecedented importance. Herein, we utilized Perovskite-based oxide compounds barium titanate (BaTiO) and strontium titanate (SrTiO) nanoparticles as anode materials for lithium-ion batteries from straightforward and standard carbonate-based electrolyte with 10% fluoroethylene carbonate (FEC) additive [1M LiPF (1:1 EC: DEC) + 10% FEC]. SrTiO and BaTiO electrodes can deliver a high specific capacity of 80 mA h g at a safe and low average working potential of ≈0.

Effects of parity and early pregnancy on peripheral blood leukocytes in dairy cattle.

Subfertility remains a major problem in the dairy industry. Only 35% to 40% of high-yielding dairy cows and 55% to 65% of nonlactating heifers become pregnant after their first service. The immune system plays a critical role in the establishment of pregnancy.

Effects of parity and early pregnancy on peripheral blood leukocytes in dairy cattle.

Building a Rechargeable Voltaic Battery via Reversible Oxide Anion Insertion in Copper Electrodes.

Voltaic pile, the very first battery built by humanity in 1800, plays a seminal role in battery development history. However, the premature design leads to the inevitable copper ion dissolution issue, which dictates its primary battery nature. To address this issue, solid-state electrolytes, ion exchange membranes, and/or sophisticated electrolytes are widely utilized, leading to high costs and complicated cell configuration.

Bimetallic Cobalt-Nickel Selenide Nanocubes Embedded in a Nitrogen-Doped Carbon Matrix as an Excellent Li-Ion Battery Anode.

Lithium-ion batteries (LIBs) have been widely used for portable electronics and electric vehicles; however, the low capacity in the graphite anode limits the improvement of energy density. Transition-metal selenides are promising anode material candidates due to their high theoretical capacity and controllable structure. In this study, we successfully synthesize a bimetallic transition-metal selenide nanocube composite, which is well embedded in a nitrogen-doped carbon matrix (denoted as CoNiSe/NC).

Determination and Evaluation of Sense of Coherence in Women in Semi-urban Nepal: A part of the Heart-health Associated Research, Dissemination, and Intervention in the Community (HARDIC) Trial.

Background Sense of coherence (SOC) is a core concept of salutogenesis which relates to individuals' overall life orientation. Stronger SOC associates with better coping strategies, better health, and better quality of life. Although the SOC-questionnaire is validated in many cultures and languages, it has not, to date, been applied in Nepal.

Cardiovascular disease trends in Nepal - An analysis of global burden of disease data 2017.

Cardiovascular diseases (CVDs) are the leading cause of disease burden globally, disproportionately affecting low and middle-income countries. The continued scarcity of literature on CVDs burden in Nepal has thwarted efforts to develop population-specific prevention and management strategies. This article reports the burden of CVDs in Nepal including, prevalence, incidence, and disability basis as well as trends over the past two decades by age and gender.

Defective Proventriculus Regulates Cell Specification in the Gastric Region of Intestine.

The gastrointestinal tract in metazoans consists of diverse epithelial cells with distinct cell morphology and physiological functions. The development and homeostasis of gastrointestinal epithelia involve spatiotemporal regulation by many signaling pathways, essential to confer their region-specific function and identity. The adult midgut and the mammalian intestine share a high degree of conservation between such signaling pathways.
