We study the influence of electrical biasing on the modification of the chemical composition and electrical performance of perovskite solar cells (PSCs) by coupling electrochemical impedance spectroscopy (EIS) and scanning transmission X-ray microscopy (STXM) techniques. EIS reveals the formation of charge accumulation at the interfaces and changes in the resistive and capacitive properties. STXM study on PSCs after applying a strong electric field for a long biasing time indicates the breakdown of methylammonium (MA) cation, promoting iodide ions to migrate and create defects at the interface.

Background: Results of the National Lung Screening Trial create the potential to reduce lung cancer mortality, but community translation of lung cancer screening (LCS) has been challenging. Subsequent policies have endorsed informed and shared decision-making and using decision support tools to support person-centered choices about screening to facilitate implementation. This study evaluated the feasibility and acceptability of LuCaS CHOICES, a web-based decision aid to support delivery of accurate information, facilitate communication skill development, and clarify personal preferences regarding LCS-a key component of high-quality LCS implementation.

Radiography is a field of medicine inherently intertwined with technology. The dependency on technology is very high for obtaining images in ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MRI). Although the reduction in radiation dose is not applicable in US and MRI, advancements in technology have made it possible in CT, with ongoing studies aimed at further optimization.

Low-carbon fuels, emitting less carbon than fossil fuels, are proposed to help in the transition to a sustainable, decarbonized transport sector. The new biofuels being studied and developed in this context include hydrotreated vegetable oils (HVO). Its chemical composition, which is the same as fossil diesel (primarily composed of linear chain hydrocarbons C12-C24), makes HVO (more homogeneous mixtures of paraffinic hydrocarbons C10-C20, containing no sulfur or aromatics) a fuel with slightly lower density than fossil diesel due to these characteristics.
