We investigate a van der Waals heterostructure constructed using BP and C3N and investigate its use as an anode for lithium-, sodium- and potassium-ion batteries.

Cirrhosis is an immunocompromised state that leads to various infections, with an estimated 30% mortality. Pakistan already has a high morbidity and mortality related to complications of cirrhosis. Where the data on infection among cirrhotics is scanty, this study aimed to determine the frequency, microbiological spectrum and various risk factors of infections in cirrhosis of liver. This is a prospective cohort study conducted at a tertiary care hospital. The microbiological spectrum and frequency of infections was determined in cirrhotics.

The adsorption of molecules NH 3 , CH 4 , and H 2 O are studied on pristine and indium doped phosphorene (In@P). For adsorption, armchair (AC), zigzag, and isotropic/square supercells are used. We have calculated structural, adsorption energies and electronic properties using the first-principles method. The most stable configurations for adsorption on doped phosphorene are determined, and the adsorption sites, energies, binding distances, electronic structure, and charge transfers are calculated. The adsorption energies of adsorbate molecules on In@P are significantly improved compared to undoped phosphorene. The electrical conductivity is calculated using the Boltzmann transport equation. It is found that all three molecules are physisorbed on In@P, and NH 3 and H 2 O can be detected with high sensitivity. The outstanding recovery time (few μs) is found for H 2 O and NH 3 on AC supercells. These findings indicate that In@P could be a promising material for gas sensing applications.

Background Integration of mental health and psychosocial support (MHPSS) into primary health care in the Gaza Strip involves the delivery of mental health services within the essential service package provided by UNRWA, as recommended by WHO to fill the treatment gap. In early 2016, a successful pilot demonstrated that the integration is achievable in limited resource settings, and resulted in the adoption of a stepped care model to screen, identify, support, and treat patients. This study aimed to evaluate the MHPSS integration process and outcomes at UNRWA health centres in the Gaza Strip. MethodsWe used a descriptive analytical study design, with quantitative and qualitative data collected from records, and individual feedback from patients and health care providers (HCPs). The study was performed in the 22 UNRWA health centres of the Gaza Strip and all participants agreed to participate either verbally or by written consent. Approval was also obtained from the UNRWA Health Program Gaza Field Office.
