Bacteria of the genus are the most studied microorganisms that biodegrade persistent perfluoroorganic pollutants, and the research of their application for the remediation of environmental sites using biotechnological approaches remains relevant. The aim of this study was to investigate the ability of a known destructor of perfluorooctane sulfonic acid from the genus to accelerate and enhance the destruction of long-chain perfluorocarboxylic acids (PFCAs), specifically perfluorooctanoic acid and perfluorononanoic acid, in water and soil in association with the strain . 5(3), which has previously confirmed genetic potential for the degrading of PFCAs.

(Mtb) is the causative agent of tuberculosis, the world's deadliest infectious disease. Mtb uses a variety of mechanisms to evade the human host's defenses and survive intracellularly. Mtb's oxidative stress response enables Mtb to survive within activated macrophages, an environment with reactive oxygen species and low pH.

The oxygen evolution reaction (OER), which involves a four-electron transfer and slow kinetics, requires an efficient catalyst to overcome the high energy barrier for high-performance water electrolysis. In this paper, a novel NiS@V-NiFe(III) LDH/NF catalyst was prepared via a facile two-step hydrothermal method. The constructed heterostructure of NiS@V-NiFe(III) LDH increases the specific surface area and regulates the electronic structure.

With the rapid growth of the world population and economy, the greenhouse effect caused by CO emissions is becoming more and more serious. To achieve the "two-carbon" goal as soon as possible, the carbon dioxide reduction reaction is one of the most promising strategies due to its economic and environmental friendliness. As an analog of graphene, monolayer h-BN is considered to be a potential catalyst.

We report the design and development of a novel multifunctional nanostructure, RB-AuSiO_HSA-DOX, where tri-modal cancer treatment strategies-photothermal therapy (PTT), photodynamic therapy (PDT), chemotherapy-luminescent properties and targeting are integrated into the same scaffold. It consists of a gold core with optical and thermo-plasmonic properties and is covered by a silica shell entrapping a well-known photosensitizer and luminophore, Rose Bengal (RB). The nanoparticle surface was decorated with Human Serum Albumin (HSA) through a covalent conjugation to confer its targeting abilities and as a carrier of Doxorubicin (DOX), one of the most effective anticancer drugs in clinical chemotherapy.
