Among various available materials used in transparent and flexible devices, MXenes are attracting attention as a brand-new candidate this category. Ti3C2Tx MXene 2D material has exceptional properties, making it potential having numerous applications different areas. Because of its high conductivity, can be conducting electrodes (TCEs). In study, the etched by highly concentrated acid at 50 °C,were spin-coated on polyethylene terephthalate (PET) film annealed moderate temperatures up to 170...
Polymer-dispersed liquid crystals (PDLCs), an indispensable class of electrically switchable materials, where nano- or microsized crystal (LC) droplets are phase-separated from the polymer matrix, have been widely used in fabrication highly efficient and systematic smart windows.

Due to its semiconducting nature, controlled growth of large-area chemical vapor deposition (CVD)-grown two-dimensional (2D) molybdenum disulfide (MoS2) has a lot potential applications in photodetectors, sensors, and optoelectronics. Yet the controllable, large-area, cost-effective highly crystalline MoS2 remains challenge. Confined-space CVD is very promising method for manner. Herein, we report large-scale with different morphologies using NaCl as seeding promoter confined-space CVD....
Low-rank adaptation (LoRA) has emerged as a powerful method for fine-tuning large-scale foundation models. Despite its popularity, the theoretical understanding of LoRA remained limited. This paper presents analysis by examining connection to Mixture Experts Under this framework, we show that simple reparameterizations matrices can notably accelerate low-rank matrix estimation process. In particular, prove reparameterization reduce data needed achieve desired error from an exponential...
Abstract We investigate the transport behavior of two-terminal graphene ballistic devices with bias voltages up to a few volts suitable for electronics applications. Four based designs, specially fabricated from mechanically exfoliated encapsulated by hexagonal boron nitride, exhibit strong nonlinear I-V characteristic curves at room temperature. A maximum asymmetry ratio 1.58 is achieved current 60 µA temperature through limited thermal effect higher bias. An analytical model using specular...
