Antibiotic prescribing practices and perceptions on antimicrobial resistance among healthcare practitioners in Russia.

Objectives: Antimicrobial resistance (AMR) is a growing global health threat. The misuse of antibiotics is the main factor contributing to the development of AMR. Healthcare practitioners (HCPs) play a crucial role in the use of antibiotics.

European Countries Step-up Humanitarian and Medical Assistance to Ukraine as the Conflict Continues.

On the 24th of February 2022, the Russian Federation began an unprovoked invasion of Ukraine, marking the biggest military attack in Europe since the second world war. Over 4 million people have fled their homeland within the first month of the war and have triggered a large refugee crisis with impacts far beyond the Ukrainian border. People in the neighboring countries have shown tremendous support by stepping forward to donate food, clothes, medications, money, and other essential supplies.

Numerical Modeling of an Organic Electrochemical Transistor.

We develop a numerical model for the current-voltage characteristics of organic electrochemical transistors (OECTs) based on steady-state Poisson's, Nernst's and Nernst⁻Planck's equations. The model starts with the doping⁻dedoping process depicted as a moving front, when the process at the electrolyte⁻polymer interface and gradually moves across the film. When the polymer reaches its final state, the electrical potential and charge density profiles largely depend on the way the cations behave during the process.

Spiro-configured phenyl acridine thioxanthene dioxide as a host for efficient PhOLEDs.

A new high triplet organic semi-conductor based on a donor-spiro-acceptor design has been synthesised and used as a host material in high performance (EQE = 11.4%) sky blue phosphorescent organic light emitting diodes.
