2D WS nanosheets (NSs) are gaining popularity in the domain of Li-ion batteries (LIBs) due to their unique structures, which can enable reversible insertion and extraction of alkali metal ions. While synthesis methods have mostly relied on the exfoliation of bulk materials or direct growth on substrates, here we report an alternative approach involving colloidal hot-injection synthesis of 2D WS in 2H and 1T' crystal phases followed by their electrophoretic deposition (EPD) on the current collector. The produced 2D WS NSs' films do not require any additional additives during deposition, which boosts the energy density of the additive-free LIBs produced.

Herein, we present the use of electrophoretic deposition (EPD) to fabricate binder-free electrodes consisting of Sb nanoparticles (NPs) embedded in interconnected multiwalled carbon nanotubes (MWCNTs). The anode architecture allows volume changes to be accommodated and prevents Sb delamination within the binder-free electrodes.

Aims: The atrioventricular block (AVB) is a conduction system problem that results from the impairment in the transmission of an impulse from the atria to the ventricle, the disease has many etiologies. This article aimed to evaluate the efficacy and safety of dual and single-chamber pacemakers in patients with SSS and AVB.
Methods: An electronic search of PubMed (Medline), EMBASE, and Google Scholar was performed from 2000 till August 15th, 2022.
Here, we report the solution phase synthesis of axial heterostructure Si and Ge (hSG) nanowires (NWs). The NWs were grown in a high boiling point solvent from a low-cost Sn powder to achieve a powder form product which represents an attractive route from lab-scale to commercial application. Slurry processed anodes of the NWs were investigated in half-cell ( Li-foil) and full-cell ( NMC811) configurations of a lithium ion battery (LIB).

Thiamine deficiency is one of the risk factors responsible for causing HF; other risk factors include hypertension, smoking, and obesity.
Objective: We conducted a systemic review and meta-analysis of RCTs to scrutinize whether the heart failure patients would benefit from thiamine supplementation or not when compared to placebo.
Introduction: The molecular research has raised copious hypotheses about different molecular effects on the variable expression of the current virus on the human body. The present prospective study aims to determine clinically as well as statistically, the relation between ABO blood groups and Rhesus (Rh) factor and the severity of the Covid-19 virus.
Research Design And Methods: We conducted a prospective, single-centered study at The Combined Military Hospital Lahore, Pakistan.
Despite significant efforts to fabricate high energy density (ED) lithium (Li) metal anodes, problems such as dendrite formation and the need for excess Li (leading to low N/P ratios) have hampered Li metal battery (LMB) development. Here, the use of germanium (Ge) nanowires (NWs) directly grown on copper (Cu) substrates (Cu-Ge) to induce lithiophilicity and subsequently guide Li ions for uniform Li metal deposition/stripping during electrochemical cycling is reported. The NW morphology along with the formation of the Li Ge phase promotes uniform Li-ion flux and fast charge kinetic, resulting in the Cu-Ge substrate demonstrating low nucleation overpotentials of 10 mV (four times lower than planar Cu) and high Columbic efficiency (CE) efficiency during Li plating/stripping.
View Article and Find Full Text PDFLithium (Li) metal batteries (LMBs) provide superior energy densities far beyond current Li-ion batteries (LIBs) but practical applications are hindered by uncontrolled dendrite formation and the build-up of dead Li in "hostless" Li metal anodes. To circumvent these issues, we created a 3D framework of a carbon paper (CP) substrate decorated with lithiophilic nanowires (silicon (Si), germanium (Ge), and SiGe alloy NWs) that provides a robust host for efficient stripping/plating of Li metal. The lithiophilic Li Si , Li (Si Ge ) and Li Ge formed during rapid Li melt infiltration prevented the formation of dead Li and dendrites.

Introduction: Schizophrenia is a complex medical illness characterized by hallucinations, delusions, and cognitive issues. Olanzapine, a second-generation antipsychotic widely prescribed for schizophrenia has proven to be efficacious, however, its use is associated with major adverse effects such as weight gain, metabolic syndrome and diabetes mellitus. Recently, FDA approved a combination dose of olanzapine and samidorphan (OLZ/SAM) to mitigate the adverse outcomes associated with olanzapine use for the treatment of Schizophrenia.
