Published: March 2016

An efficient transition-metal free tandem cyclization of functionalized alkenes with easily available thiocyanate salts has been developed under mild conditions. This protocol offers a simple, easy-to-handle, and atom-economical method for the synthesis of SCN-containing dihydrofurans and lactones with good to excellent yields. A detailed mechanistic investigation indicates that a tandem radical pathway is involved in this transformation.

Biological neural systems seamlessly integrate perception and action, a feat not efficiently replicated in current physically separated designs of neural-imitating electronics. This segregation hinders coordination and functionality within the neuromorphic system. Here, we present a flexible device tailored for neuromorphic computation and muscle actuation.

The activation mechanism of Li-rich cathode has been discussed for many years, yet there is still debate on different theories. Potassium doping can assist the investigation on activation mechanism through its unique function in terms of blocking TM migration during activation.   K-doping works by occupying Li sites even after Li has been extracted, increasing stability by blocking transition metals from migrating into these sites, which can help us distinguish the pathway of activation.

Nanoconfinement at the interface of heterogeneous Fenton-like catalysts offers promising avenues for advancing oxidation processes in water purification. Herein, we introduce a template-free strategy for synthesizing nanoconfined catalysts from municipal sludge (S-NCCs), specifically engineered to optimize reactive oxygen species (ROS) generation and utilization for rapid pollutant degradation. Using selective hydrofluoric acid corrosion, we create an architecture that confines atomically dispersed Fe centers within a micro-mesoporous carbon matrix in situ.

Two-dimensional (2D) van der Waals materials are shaping the landscape of next-generation devices, offering significant technological value thanks to their unique, tunable, and layer-dependent electronic and optoelectronic properties. Time-domain spectroscopic techniques at terahertz (THz) frequencies offer noninvasive, contact-free methods for characterizing the dynamics of carriers in 2D materials. They also pave the path toward the applications of 2D materials in detection, imaging, manufacturing, and communication within the increasingly important THz frequency range.

Two-dimensional (2D) semiconductors have attracted a considerable amount of interest as channel materials for future transistors. Patterning of 2D semiconductors is crucial for separating continuous monolayers into independent units. However, the state-of-the-art 2D patterning process is largely based on photolithography and high-energy plasma/RIE etching, leading to unavoidable residues and degraded device uniformity, which remains a critical challenge for the practical application of 2D electronics.
