Kinetics analysis of radical photopolymerizations for UV-curable nanocomposites based on cellulose nanocrystals: Promoting and enhancing mechanisms.

The interfacial interactions between the enhanced nanoscale components and the polymer matrix, as well as the photopolymerization behavior of the composite system, are of paramount importance to the quality and performance of photo-curable nanocomposites. Cellulose nanocrystals (CNCs), a novel class of green reinforcing materials, are anticipated to facilitate the development of high-performance applications of advanced functional materials. Herein, the promoting and enhancing effects of modified CNCs on photo-curable nanocomposites are studied.

Quantum Phase Transition as a Promising Route to Enhance the Critical Current in Kagome Superconductor CsVSb.

Developing strategies to systematically increase the critical current, the threshold current below which the superconductivity exists, is an important goal of materials science. Here, the concept of quantum phase transition is employed to enhance the critical current of a kagome superconductor CsVSb, which exhibits a charge density wave (CDW) and superconductivity that are both affected by hydrostatic pressure. As the CDW phase is rapidly suppressed under pressure, a large enhancement in the self-field critical current (I) is recorded.

Modification of nanocellulose via atom transfer radical polymerization and its reinforcing effect in waterborne UV-curable resin.

Cellulose nanocrystals (CNCs) are green reinforcing materials, and their potential has been evaluated in the preparation of waterborne UV-curable resin composites with high-performance.

Using tert-butyl acrylate as the monomer, the nanocellulose grafted copolymer CNC-g-PtBA was successfully synthesized via atom transfer radical polymerization (ATRP) in the presence of a macromolecular initiator.

Nodeless Superconductivity in Kagome Metal CsVSb with and without Time Reversal Symmetry Breaking.

The kagome metal CsVSb features an unusual competition between the charge-density-wave (CDW) order and superconductivity. Evidence for time reversal symmetry breaking (TRSB) inside the CDW phase has been accumulating. Hence, the superconductivity in CsVSb emerges from a TRSB normal state, potentially resulting in an exotic superconducting state.

Patterned diamond anvils prepared via laser writing for electrical transport measurements of thin quantum materials under pressure.

Quantum materials exhibit intriguing properties with important scientific values and huge technological potential. Electrical transport measurements under hydrostatic pressure have been influential in unraveling the underlying physics of many quantum materials in bulk form. However, such measurements have not been applied widely to samples in the form of thin flakes, in which new phenomena can emerge, due to the difficulty in attaching fine wires to a thin sample suitable for high-pressure devices.

Several new sensing algorithms use deep neural network algorithms and consume even more computation resources.

Pressure-induced enhancement of the superconducting transition temperature in LaOBiAgS.

Charge density wave (CDW) instability is often found in phase diagrams of superconductors such as cuprates and certain transition-metal dichalcogenides. This proximity to superconductivity triggers the question on whether CDW instability is responsible for the pairing of electrons in these superconductors. However, this issue remains unclear and new systems are desired to provide a better picture.
