A DFT study of the adsorption behavior and sensing properties of CO gas on monolayer MoSe in CO-rich environment.

Context: Carbon monoxide, also known as the "silent killer," is a colorless, odorless, tasteless, and non-irritable gas that, when inhaled, enters the bloodstream and lungs, binds with the hemoglobin, and blocks oxygen from reaching tissues and cells. In this work, the monolayer MoSe-based CO gas sensors were designed using density functional theory calculation with several dopants including Al, Au, Pd, Ni, Cu, and P. Here, Cu and P were found to be the best dopants, with adsorption energies of -0.

A survey of surveys: an evaluation of the quality of published surveys in neurosurgery.

Purpose: Surveys generate valuable data in epidemiologic and qualitative clinical research. The quality of a survey depends on its design, the number of responses it receives, and the reporting of the results. In this study, we aimed to assess the quality of surveys in neurosurgery.

Myths, beliefs, and attitude toward cancer among the family caregivers of cancer patients: A community-based, mixed-method study in rural Tamil Nadu.

Background And Aim: Family support is one of the most crucial components of cancer care. The familial beliefs and myths associated with cancer can seriously affect the quality of life and treatment outcome of cancer patients. This study intends to explore the prevailing myths, beliefs, and attitude toward cancer among the family caregivers of cancer patients.

COMMENT: Ethics and professionalism of a community health worker: A virtue ethics approach.

Community health workers are the link between the community and the health system, delivering primary care services at the frontline. Every profession has its own ethics and professional values, and there is a need to formulate the ethics of community health work which should be informed by their rich experiential wisdom. In one such effort, we interviewed a senior community health worker in the Tamil Nadu health system and present it here as a virtue ethics case study.

Assessment of the mechanical properties of monolayer graphene using the energy and strain-fluctuation methods.

Molecular statics and dynamics simulations were performed to investigate the mechanical properties of a monolayer graphene sheet using an efficient energy method and strain-fluctuation method. Using the energy method, we observed that the mechanical properties of an infinite graphene sheet are isotropic, whereas for a finite sheet, they are anisotropic. This work is the first to report the temperature-dependent elastic constants of graphene between 100 and 1000 K using the strain-fluctuation method.
