Resistive strain/pressure sensors have attracted intensive attention due to their irreplaceable role in the fields of motor behavior monitoring, human health diagnosis, and human machine interface. Notably, the material and structural design have significant impacts on the performance of resistive strain/pressure sensors. Biomass-derived carbons (BDCs) are considered as popular candidates for realizing the fabrication of resistive strain/pressure sensors because of their excellent properties such as abundant sources, diverse structures, and satisfactory electrical conductivity. This review presents the recent progress of BDCs in the field of resistive strain/pressure sensors and their key challenges. First, the classification methods, evaluation criteria and sensing mechanisms of previously reported resistive strain/pressure sensors are systematically outlined and discussed. Subsequently, the preparation of BDCs with different macrostructures, including one-dimensional (1D), 2D, and 3D structures, and their recent progress in the field of resistive strain/pressure sensors are summarized. Next, the respective advantages of BDCs with different macroscopic structures in the field of resistive strain/pressure sensors are carefully analyzed, and the relationship between different structures and the comprehensive sensing performances of devices is discussed. Finally, the future prospects and major challenges are proposed for BDC-based resistive strain/pressure sensors, and some key future research directions are given.

“…To the best of our knowledge, the literature concerning the piezocatalytic approach for the transformation of methane into alcohol (or ethanol) is rare, indicating a significant scope in the field. More piezoelectric materials with a single crystal, , ceramic-based, , and metal oxide of nanosized , could be explored to evaluate their performance in piezocatalytic MTE conversions. Nevertheless, the piezocatalytic approach utilizes mechanical energy instead of thermal energy, which makes it cost-effective.…”

Methane, which is a greenhouse gas, is released into the atmosphere through anthropogenic activities. An increase in the methane content in the atmosphere is 25 times more harmful than carbon dioxide; hence, utilizing and converting it into liquid fuels (or ethanol) could be a viable option. Industrially, methane is oxidized into syngas, followed by Fischer−Tropsch synthesis, producing liquid hydrocarbons. The process requires harsh conditions (i.e., 700−800 °C and 20−30 bar) to activate the methane C−H bond and thus become energy intensive. Recently, newer techniques have demonstrated methane C−H bond activation followed by its conversion into ethanol near ambient conditions, owing to lesser energy requirements and reduced process cost. This review assembles recent developments in one-step methane-to-ethanol (MTE) conversions comprising thermocatalytic, photocatalytic, piezocatalytic, electrocatalytic, and nonthermal plasma (NTP) routes. Thermocatalytic processes provided the highest ethanol yield from methane, while piezocatalytic, photocatalytic, and electrocatalytic processes appeared economically attractive for large-scale employment because of ambient operating conditions. The NTP without a catalyst enabled better ethanol selectivity but with higher coke formation. The insights into each technique are critically discussed in light of experimental findings. The molecular studies helped to further elucidate the MTE conversion mechanism. Further, the fate of new techniques for the ethanol market (considering ethanol demand in transportation and chemical manufacturing) is presented. This review is crucial for researchers investigating MTE conversions (with optimized operating conditions) for increased ethanol production.

This study provides a comprehensive analysis of a biofabricated nanomaterial derived from Sansevieria trifasciata root extract, evaluating its structural, morphological, and optical properties for use in asymmetric supercapacitors. The nanomaterial comprises pristine ZnO nanoparticles (ZnO NPs) and a 1% Ag-doped ZnO nanocomposite (Ag@ZnO NC), synthesized through a green-assisted sol−gel autocombustion method. Employing techniques such as Xray diffraction, ultraviolet−visible near-infrared, scanning electron microscopy− energy-dispersive X-rayspectroscopy, Fourier transform infrared spectroscopy, Raman spectroscopy, and transmission electron microscopy, the study confirms a hexagonal wurtzite structure and nanocrystallites with spherical and hexagonal shapes (30 nm). Optical analysis reveals a red shift in the band gap with Ag doping, indicating improved conductivity. The material shows potential applications in solar cells, optoelectronics, spintronics, wastewater treatment, and high-performance asymmetric supercapacitors. Raman spectra validate the wurtzite phase and identify intrinsic defects. Electrochemical tests demonstrate remarkable supercapacitive behavior with a 94% capacitance retention after 10,000 cycles, highlighting its promise as advanced asymmetric supercapacitors.
