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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
