Phographene as a new carbon allotrope for adsorption and detection of SO, AsH, NO, CFH, and CO air pollutant gaseous species.

Context: Phographene and its family member structures are of the newly proposed semiconductors for detection of chemicals. That is, in this project, the potential of using α-phographene (α-POG) both for adsorption and detection of five types of the most important air pollutant gases containing SO, AsH, CFH, NO, and CO species were investigated.  The results of the time dependent density functional theory (TD-DFT) calculations indicate that during the adsorption of NO, and SO by the sorbent, big redshifts occur (up to 866.

Prevalence of Genes Encoding Aminoglycoside-Modifying Enzymes and armA among Acinetobacter baumannii Clinical Isolates in Alexandria, Egypt.

Introduction: Acinetobacter baumannii (A.baumannii) is a ubiquitous pathogen responsible for serious infections in hospitalized patients with a high propensity to develop resistance to antimicrobial agents. The study aimed to determine the antimicrobial resistance patterns and the prevalence of aminoglycoside resistance genes among A.
