Atomically thin amorphous carbon with an ultralow dielectric constant

Two-dimensional (2D) materials could replace conventional electronic components. Key advances have already been made in applying 2D materials to integrated circuits, but a robust, atomically thin ultralow-k dielectric remains crucial for further circuit scaling. Minimizing parasi...

Yu-Shiba-Rusinov-assisted Andreev transport in a molecular junction between superconductors

Magnetic impurities in superconductors host Yu-Shiba-Rusinov (YSR) bound states, whereas weak superconducting junctions sustain subharmonic charge transport through multiple Andreev reflections (MAR). We explore these phenomena using a molecular-scale junction created by placing...

How Polymer ChainsRemember Their Crystalline Past:Simulations Uncover the Molecular Origin of Melt Memory

Abstract Melt memory in semicrystalline polymers is the remarkable ability of polymer chains to retain structural information from a prior crystalline state after being heated above the melting temperature. This phenomenon can induce extraordinary self-nucleation and strongly inf...

An integrated circularity and life cycle assessment of power electronic converters: key hotspots and improvement opportunities

The rapid electrification of energy systems relies heavily on power electronic converters (PECs), which enable efficient electricity conversion and control in applications such as industrial drives, renewable energy systems, and electric mobility. However, despite their high oper...

Defect Topology Governs Lithiation Pathways in Graphite Anodes

ABSTRACT The electrochemical behavior of graphite anodes is strongly affected by structural disorder, yet graphite crystallinity is often described using averaged descriptors that do not resolve the underlying defect landscape. Here, we investigate a series of industrially releva...

Driving Forcesof UCST and LCST Liquid–Liquid Phase Separations

Abstract A liquid mixture of two or more components can phase separate into two liquid phases by changing the temperature. Ordinary chemical perception would attribute this transition to a competition between the favorable enthalpy of the biphasic state and the favorable entropy...

Rate-Programmable Interfacial Resistive Switching with Tunable Volatility in CuCrP2S6

Metal thiophosphates are emerging as a multifunctional material platform for neuromorphic electronics due to their accessible polar phases and ion dynamics on biologically relevant timescales. While resistive switching in these materials is frequently attributed to ferroelectric...

Iron Oxide Nanoparticles for Ligand‐Mediated Targeted Imaging

Superparamagnetic iron oxide nanoparticles (SPIONs) are widely employed as platforms for ligand-mediated targeting in multimodal imaging and targeted therapeutic applications owing to their intrinsic magnetic properties and versatility for surface and core modification. In additi...

Colorectal Cancer Mortality Following an Organized Fecal Immunochemical Test–Based Screening Program

Importance Colorectal cancer (CRC) is a leading cause of cancer-related mortality worldwide. Organized screening programs using the fecal immunochemical test (FIT) have been implemented to reduce CRC mortality through early detection. Objectives To evaluate the association betwee...

Toward more accurate natural orbital functional approximations: Including 4-index cumulant contributions

Accurate modeling of bond breaking remains a central challenge for reduced density matrix functional theory (RDMFT). Although some modern functionals can yield reasonably accurate dissociation energies, they often fail to reproduce key properties of the dissociated fragments, suc...
