We explore the possibility of a Berezinskii-Kosterlitz-Thouless-like critical phase for the charge degrees of freedom in the intermediate-temperature regime between the charge-ordered and disordered phases in two-dimensional systems with competing short-range Coulomb repulsion. As the simplest example, we investigate…
We perform a systematic study of the Zitterbewegung effect of fermions, which are described by a Gaussian wave with broken spatial-inversion symmetry in a three-dimensional low-energy Weyl semimetal. Our results show that the motion of fermions near the Weyl points is characterized by rectilinear motion and Zitterbewe…
Abstract Monolayers of transition metal dichalcogenides (TMDs) are characterized by an extraordinarily strong Coulomb interaction giving rise to tightly bound excitons with binding energies of hundreds of meV. Excitons dominate the optical response as well as the ultrafast dynamics in TMDs. As a result, a microscopic…
The development of new bioactive food-packaging materials that extend the shelf life of food is an important objective. Herein, we report the fabrication of four polylactic acid/tea polyphenol (PLA/TP) composite nanofibers, with PLA/TP ratios of 5:1, 4:1, 3:1, and 2:1, by electrospinning. The morphological quality of…
Purpose To compare the long-term brain elimination kinetics and gadolinium species in healthy rats after repeated injections of the contrast agents gadodiamide (a linear contrast agent) or gadoterate (a macrocyclic contrast agent). Materials and Methods Nine-week-old rats received five doses of 2.4 mmol gadolinium per…
Heteroatom-doped carbon dots (C-dots) have captured widespread research interest owing to high fluorescence and biocompatibility for multimodal bioimaging applications. Here, we exemplify a rapid, facile synthesis of ethylenediamine (EDA)-functionalized transition metal ion (Mn 2+, Fe 2+, Co 2+, and Ni 2+ )-doped C-do…
The rapid growth of energy demand and lack of sustainable energy conversion/storage devices have made the supercapacitor an inevitable substitute to current storage systems. However, the major limitation to the cutting edge lies in superconductors’ relatively low energy density compared to batteries. Here, we report L…
Abstract High-nuclearity silver clusters are appealing synthetic targets for their remarkable structures, but most are isolated serendipitously. We report here six giant silver-thiolate clusters mediated by solvents, which not only dictate the formation of an octahedral Ag 6 4+ kernel, but also influence the in situ-g…
Abstract 2D materials hold great potential for designing novel electronic and optoelectronic devices. However, 2D material can only absorb limited incident light. As a representative 2D semiconductor, monolayer MoS 2 can only absorb up to 10% of the incident light in the visible, which is not sufficient to achieve a h…
Designing battery-type materials with good electrocapacitive performance and high electrical conductivity is necessary to improve the energy-storage capability of an battery-supercapacitor hybrid devices (BSH). Ternary metal oxides are synthesized by using a hydrothermal reaction with an extra metal of Mo, Fe, Cu, Zn,…
Abstract An efficient strategy (enhanced metal oxide interaction and core–shell confinement to inhibit the sintering of noble metal) is presented confined ultrathin Pd‐CeO x nanowire (2.4 nm) catalysts for methane combustion, which enable CH 4 total oxidation at a low temperature of 350 °C, much lower than that of a c…
Manipulating physical properties using the spin degree of freedom constitutes a major part of modern condensed matter physics and is a key aspect for spintronics devices. Using the newly discovered two-dimensional van der Waals ferromagnetic CrI 3 as a prototype material, we theoretically demonstrated a giant magneto…
The recent discovery of topological semimetals has stimulated extensive research interest due to their unique electronic properties and novel transport properties related to a chiral anomaly. However, the studies to date are largely limited to bulk crystals and exfoliated flakes. Here, we report the controllable synth…
High Resolution Image Download MS PowerPoint Slide Chirality plays an essential role in life, providing unique functionalities to a wide range of biomolecules, chemicals, and drugs, which makes chiral sensing and analysis critically important. The wider application of chiral sensing continues to be constrained by the…
We present a general thermodynamic top-down analysis of the effects of oxidants and pH on dopamine oxidation and cyclization, supplemented with UV-vis and electrochemical studies. The model is applicable to other catecholamines and various experimental conditions. The results show that the decisive physicochemical par…
The first example of a smart crystalline material, the 2:1 cocrystal of probenecid and 4,4'-azopyridine, which responds reversibly to multiple external stimuli (heat, UV light, and mechanical pressure) by twisting, bending, and elastic deformation without fracture is reported. This material is also able to self-heal o…
Absorbable metals, metals that corrode in physiological environment, constitute a new class of biomaterials intended for temporary medical implant applications. The introduction of these metals has shifted the established paradigm of metal implants from preventing corrosion to its direct application. Interest toward a…
The development of accurate and transferable machine learning (ML) potentials for predicting molecular energetics is a challenging task. The process of data generation to train such ML potentials is a task neither well understood nor researched in detail. In this work, we present a fully automated approach for the gen…
A new technique of liquid phase epitaxy has been proposed in this work. It allows to eliminate known disadvantages of liquid phase epitaxy by creating short-time contact between a substrate and a solution-melt, as well as due to segmental deposition of an epitaxial layer over the working substrate surface. The short-t…
The nonclassical heteropolyoxotungstate [P3W6(O2)6(OH)2O22]7– has been successfully synthesized and characterized well by various techniques such as FT‐IR, UV/Vis, TGA, as well as elemental analysis. The single‐crystal X‐ray analysis reveals that the two {PW3(O2)3(OH)O9} subunits are linked together through a {PO4} gr…
