Article Abstract
Textile electronics are ideal for novel electronic devices owing to their flexibility, light weight, and wearability. In this work, wearable organic field-effect transistors (OFETs) with all-graphene electrodes, fabricated using hot pressing, are described. First, highly conductive and flexible electrodes consisting of a cotton textile substrate and electrochemically exfoliated graphene (EEG) were prepared via hot pressing. The EEG/textile electrodes exhibited a low sheet resistance of 1.3 Ω sq and high flexibility; these were used as gate electrodes in the wearable OFETs. In addition, spray-coated EEG was also used as the source/drain (S/D) electrodes of the wearable OFETs, which recorded a sheet resistance of 14.8 Ω sq after hot pressing. The wearable OFETs exhibited stable electrical performance, a field-effect mobility of 13.8 cm V s, and an on-off current ratio of ~10 during 1000 cycles of bending. Consequently, the fabrication method for wearable transistors developed using textiles and hot-pressed graphene electrodes has potential applications in next-generation wearable devices.

The effect of hot isostatic pressing (HIP) on the thermoelectric power factor of zinc oxide (ZnO) has been examined. ZnO is expected to be a potential n-type oxide thermoelectric material that could enhance the thermoelectric conversion efficiency. The HIP treatment is useful for densifying the material and controlling crystal defects in the material by applying high temperatures and pressures simultaneously.

Polylactic acid (PLA) composites with high straw content face several challenges, primarily due to the inherent brittleness of straw and its poor compatibility with the polymer matrix. In this study, scanning electron microscopy (SEM) was used to analyze the microscopic structure of wheat straw chemically modified by NaOH and the silane coupling agent, and it was concluded that both treatments effectively removed waxes and silica from the surface of the straw, enhanced fiber roughness, and improved interfacial adhesion. Notably, the silane coupling agent treatment not only facilitated the formation of chemical bonds between the straw fibers and the PLA matrix but also filled the interfiber pores, significantly increasing the structural density.

Matrix effects can significantly bias Hf isotopic ratios in situ Hf isotope analyses using laser ablation (LA-) multicollector inductively coupled plasma mass spectrometry (MC-ICP-MS), necessitating the use of matrix-matched reference materials for accurate microanalysis. This work introduces a novel fast hot-pressing (FHP) sintering method to produce such reference materials efficiently for in situ analysis. By optimizing sintering temperatures, FHP technology enables the rapid preparation of in situ analysis reference materials with dense structures and homogeneous Hf isotopic compositions.

The processing techniques of camellia oil, containing freshly squeezed (FSCO), refined (DFCO), cold-pressed (OFCO), and hot-pressed (RFCO), significantly influence flavor compounds and organoleptic properties. In this study, the preference for FSCO and RFCO was revealed by sensory evaluation due to the "fruity" and "roasted" flavors, respectively. Flavor differences among oils were accurately distinguished by the E-nose.
