Multivalued logic (MVL) systems, in which data are processed with more than two logic values, are considered a viable solution for achieving superior processing efficiency with higher data density and less complicated system complexity without further scaling challenges. Such MVL systems have been conceptually realized by using negative transconductance (NTC) devices whose channels consist of van der Waals (vdW) heterojunctions of low-dimensional semiconductors; however, their circuit operations have not been quite ideal for driving multiple stages in real circuit applications due to reasons such as a reduced output swing and poorly defined logic states. Herein, we demonstrate ternary inverter circuits with near rail-to-rail swing and three distinct logic states by employing vdW p-n heterojunctions of single-walled carbon nanotubes (SWCNT) and MoS where the SWCNT layer completely covers the MoS layer.

The application of external electric fields to influence chemical reactions at electrode interfaces has attracted considerable interest in recent years. However, the design of electric fields to achieve highly efficient and selective catalytic systems, akin to the optimized fields found at enzyme active sites, remains a significant challenge. Consequently, there has been substantial effort in probing and understanding the interfacial electric fields at electrode/electrolyte interfaces and their effect on adsorbates.

Alopecia areata (AA) is a prevalent autoimmune condition that causes sudden hair loss and poses significant psychological challenges to affected individuals. Current treatments, including corticosteroids and Janus kinase inhibitors, fail to provide long-term efficacy due to adverse effects and relapse after cessation. This study introduces a nanoparticle (NP) system that codeliver diphenylcyclopropenone (DPCP) and rapamycin (RAPA) prodrugs to induce immune tolerance and promote hair regeneration.

Hydride (H) species on oxides have been extensively studied over the past few decades because of their critical role in various catalytic processes. Their syntheses require high temperatures and the presence of hydrogen, which involves complex equipment, high energy costs, and strict safety protocols. Hydride species tend to decompose in the presence of atmospheric oxygen and water, which reduces their catalytic activities.

For Zn metal batteries, the Zn anode faces several challenges, including Zn dendrites, hydrogen evolution, and corrosion. These issues are closely related to the Zn deposition process at the electrode/electrolyte interface. Herein, we propose interfacial engineering to protect the Zn anode and induce homogeneous deposition using conjugated cyclized polyacrylonitrile (cPAN) polymer nanofibers.
