Abscisic acid (ABA) mediates stress responses and growth regulation in plants, but the roles of ABA-responsive transcription factors (TFs) in Populus development remain poorly characterized. Here, we identified an ABA-upregulated TF and investigated its function through overexpression in transgenic poplar. The PtrMYBH is upregulated during ABA treatment, and its overexpression in transgenic poplar leads to leaf malformations, including reduced size and curling, with severity correlating with PtrMYBH-overexpression levels in three independent transgenic lines.

Herein, a fast Li transfer and electron-blocking interface composed of LiO/LiIn is constructed on LATP through an in situ electrochemical reaction of InO with Li metal. LiO with low Li migration energy barrier and electron-blocking injection can accelerates Li diffusion and suppresses dendrite growth at the interface.

LiCoO (LCO) is a prominent high-voltage cathode material due to its exceptional energy density and impressive theoretical specific capacity of 274 mAh g. However, challenges such as irreversible structural phase transitions, loss of reactive oxygen, and cobalt dissolution can lead to unstable interfaces between the electrolyte and the LCO cathode. In this study, sulfolane (SUL)-based composite polymer electrolytes (CPEs) were synthesized through in-situ polymerization, and the LCO cathode was modified using vinylidene carbonate (VC) and lithium difluoro(oxalato)borate (LiDFOB).

Nevertheless, current IST methodologies possess certain limitations because they are not capable of being implemented under conventional conditions, thereby limiting their practical applications. Herein, a highly mixed index facets (HMIF) strategy is proposed to construct homogeneous interfaces with gradient work function (WF) in Mott insulator NiO, accompanied by numerous oxygen vacancies.

Graphene aerogels, as a novel type of carbon-based composite material, have shown great potential in the field of wave absorption due to its characteristics of high conductivity, adjustable structure and good corrosion resistance. It is of great significance to precisely control the dielectric properties of graphene aerogel composites by effectively adjusting their microstructures through the preparing process design, ultimately leading to improve their wave-absorbing performances. In this study, two kinds of graphene/cellulose aerogel composites with three-dimensional porous structures, were successfully prepared using graphene and short staple cellulose as raw materials via the freeze-drying method based on the dissolution-regeneration strategy.

Amino acids are a class of compounds with wide-ranging applications. The synthesis of amino acids from biomass-derived α-keto acids and ammonia is a sustainable way but the unstable primary imine intermediates (R-C=NH) easily form oligomers. Herein, targeting this problem, alkaline modified mesoporous silica was employed as a support for ruthenium (Ru/M-MCM-41), which could be used as a bifunctional catalyst in the reductive amination of α-keto acids to synthesize α-amino acids.

Microwave absorption materials (MAMs) are originally developed for military purposes, but have since evolved into versatile materials with promising applications in modern technologies, including household use. Despite significant progress in bench-side research over the past decade, MAMs remain limited in their scope and have yet to be widely adopted. This review explores the history of MAMs from first-generation coatings to second-generation functional absorbers, identifies bottlenecks hindering their maturation.

Electromagnetic (EM) wave absorbers at a lower-frequency region (2-8 GHz) require higher attenuation ability to achieve efficient absorption. However, the impedance match condition and attenuation ability are usually inversely related. Herein, one-dimensional hollow carbon nanofibers with graphene nanorods are prepared based on coaxial electrospinning technology.

A popular way to solve such problems is resorting to Riemannian optimization algorithms, which yet heavily rely on both human involvement and expert knowledge about Riemannian manifolds. In this paper, we propose a Riemannian meta-optimization method to automatically learn a Riemannian optimizer.

Promotions are commonly used by e-commerce merchants to boost sales. The efficacy of different promotion strategies can help sellers adapt their offering to customer demand in order to survive and thrive. Current approaches to designing promotion strategies are either based on econometrics, which may not scale to large amounts of sales data, or are spontaneous and provide little explanation of sales volume.

However, interfacial polarization in simple structures such as particles, rods, and flakes is weak and usually plays a secondary role. In order to enhance the interfacial polarization and simultaneously reduce the electronic conductivity to avoid reflection of electromagnetic wave, a more rational geometric structure for dielectric materials is desired.

Hydrogen-bonding-initiated self-association makes the valorization of biomass-based hydroxyl compounds a formidable challenge at high concentration. Apart from enhancing the dehydration reaction of hydroxyl compounds with the noncovalent medium effects, insights into how these effects can be exploited to optimize the oxidative reactivity of concentrated hydroxyl compounds remain unclear. Herein, we elucidate that deaggregation of hydroxyl groups with a catalytic number of hydrogen bond acceptors is essential in improving the reactivity of the aerobic oxidation of biomass-based neat aromatic alcohols over the vanadium-based catalyst.

The cavities formation is theoretically considered and experimentally verified at macroscale first, and then a series of experiments are performed over a patterned surface with sub-300 nm holes by varying the pressure difference by sending a PDMS prepolymer coated mold into a vacuum chamber with changeable pressure. Results show that the air-molding method for spherical cavities fabrication is feasible not only at macroscale, but also at the nanoscale when introducing a pressure difference across the air-liquid interface.
