Air, a widely recognized dielectric material, is employed as layer in this study. We present triboelectric sensor with laser-induced graphene (LIG) electrode and an air-trapped pad using silicone rubber (SR). A very thin device thickness of 1 mm effective gap for contact–separation between the films polyimide (PI) 0.6 makes extremely highly sensitive low amplitudes pressure. The fabrication LIG material on surface PI key reason sensor. In study, we showed that fabricated padded (ATPS) has capability to generate output voltage ~32 V, short-circuit current 1.2 µA, attain maximum power density 139.8 mW m−2. performance ATPS was compared replicated having hole pad, allowing air pass through during contact–separation. observed degradation electrical suggests trapped plays crucial role enhancing voltage. Therefore, emerges ultra-sensitive healthcare sensing applications.

With the rapid development of economy and demands people’s lives, usage amount polymer materials is significantly increasing globally. Chlorobenzenes (CBS) are widely used in industrial, agriculture chemical industries, particularly as important raw during polymers processes. CBS difficult to remove due their properties, such being hydrophobic, volatile persistent biotoxic, they have caused great harm ecological environment human health. Electrochemical oxidation technology for treatment refractory pollutants has been its high efficiency easiness operation. Thus, electrochemical system was established efficient monochlorobenzene (MCB) waste gas. The effect a single factor, anode materials, cathode electrolyte concentration, current density electrode distance on removal (RE) MCB gas were first studied. response-surface methodology (RSM) investigate relationships between different factors’ conditions (current density, distance), prediction model using Design-Expert 10.0.1 software optimize reaction conditions. results one-factor experiments showed that when treating 2.90 g/m3 with 0.40 L/min flow rate, Ti/Ti4O7 an anode, stainless steel wire mesh cathode, 0.15 mol/L NaCl electrolyte, 10.0 mA/cm2 4.0 cm distance, average (RE), capacity (EC) energy consumption (Esp) 57.99%, 20.18 g/(m3·h) 190.2 (kW·h)/kg, respectively. RSM effects process parameters RE MBC follows: > concentration; interactions order concentration distance; optimal experimental 0.149 mol/L, 18.11 mA, 3.804 cm. Under these conditions, achieved 66.43%. variance analysis regression reached significant level, validation agreement predicted results, which proved feasibility model. can be applied treat processes through oxidation.

In recent years, global attention towards new energy has surged due to increasing demand and environmental concerns. Researchers have intensified their focus on energy, leading advancements in technologies like triboelectrification, which harnesses from the environment. The invention of triboelectric nanogenerator (TENG) led possibilities, with rotary sliding TENG standing out for its superior performance. However, understanding mechanical behavior remains a challenge, potentially structural issues. This paper introduces novel analytical mechanics model analyze performance stator TENG, offering solution. solution also presents an innovative approach solving axisymmetric problems elasticity theory since it challenges traditional assumption that stress function depends solely radial coordinate, proposing derive more general solution, supplementing classical elasticity. Through obtained solutions, characteristics during operation are analyzed. A clearer relationship between electrical output is expected provide theoretical basis design TENG.
