AI Article Synopsis
Article Abstract
Chemical cells that spontaneously form in simple inorganic systems are presented. The cells are surrounded by semipermeable membranes that allow water and some ions to diffuse through. These cells exhibit dynamical behaviors that are typically associated with biological entities. These behaviors may be used to perform tasks such as rotation or linear translation in the vertical and horizontal directions. Yet another system builds "curtains". Behaviors are controlled by a complex network of physical and chemical processes that are organized in space and time. The type of dynamical behavior is determined by the chemical composition of the cell and the environment. By studying these systems we may learn general rules for the growth of living entities, or at least about the spontaneous growth of complex chemical structures. Understanding and mastering the synthesis of these systems may lead to new technologies where complex structures are grown rather than assembled.

Achieving over 20% Efficiency in Laminated HTM-Free Carbon Electrode Perovskite Solar Cells through In Situ Interface Reconstruction.
Angew Chem Int Ed Engl

Shanghai Institute of Technology, School of Chemical and Environmental Engineering, CHINA.
Laminating a free-standing carbon electrode film onto perovskite film is a promising method for fabricating HTM (hole transport material)-free carbon electrode perovskite solar cells (c-PSCs), offering more flexibility by decoupling the processes of carbon electrode and perovskite layer formation. However, the power conversion efficiency (PCE) of laminated HTM-free c-PSCs (<16.5%) remains lower compared to c-PSCs with printed carbon pastes (>20%), primarily due to poor interfacial contact between the perovskite and carbon layers.

Fuel cells have become increasingly important in recent years because of their high energy efficiency and low environmental impact. However, key challenges remain in the widespread adoption of fuel-cell vehicles, including reducing Pt usage in catalysts and improving their durability. In this study, a high-performance Pt@carbon-dot-film core-shell catalyst was successfully synthesized using a nonequilibrium reaction field, , solution plasma (SP) process, by adjusting the electrolyte pH.

Viral infections trigger the integrated stress response (ISR) in eukaryotic cells that leads to the activation of eIF2α kinases, the elevation of eukaryotic translation initiation factor 2α (eIF2α) phosphorylation, and thereby the shutdown of global protein synthesis that viruses rely on to replicate. Coronaviruses and other viruses have evolved various subversion mechanisms to counteract the antiviral ISR. These intricate host-virus interactions may be exploited by pharmacologically activating the host ISR for the development of host-directed antivirals (HDAs), an increasingly relevant area of research.

Purpose: Atopic dermatitis (AD) is the most common chronic inflammatory skin disease that severely impairs patient's life quality and represents significant therapeutic challenge due to its pathophysiology arising from skin barrier dysfunction. Topical corticosteroids, the mainstay treatment for mild to moderate AD, are usually formulated into conventional dosage forms that are impeded by low drug permeation, resulting in high doses with consequent adverse effects, and also lack properties that would strengthen the skin barrier. Herein, we aimed to develop biomimetic lamellar lyotropic liquid crystals (LLCs), offering a novel alternative to conventional AD treatment.

Exosomes are vesicles ranging from 30 to 100 nanometers in size that show great potential as carriers for therapeutic uses and drug delivery. Enriching a specific set of miRNAs in exosomes emphasizes the existence of particular sorting mechanisms that manage the targeted cargo packaging. The molecular mechanism for miRNA sorting has not been understood.
