Efficient and stable electrocatalyst for oxygen evolution reaction(OER)in acidic environment is vital for polymer electrolyte membrane water electrolysis(PEMWE).In this work,we have devised the formation of heterostructured RuO_(2)/MnO_(2)with nanoflower structure for acidic OER *** to commercial RuO_(2),the overpotential at 50mA/cm^(2)is decreased by 36 mV,corresponding to a 3.7-fold better mass *** boosted acidic OER performance is attributed to the heterostructure inducing more electrons are filled in e_(g)orbital of Ru atom triggering a better deprotonation of bridge oxygen atom in Ru-O_(bri)-Mn structure evidenced by pH-independent cyclic voltammetry ***,RuO_(2)/MnO_(2)sustains its acidic OER activity within 20 h,longer than commercial RuO_(2).The membrane electrode assembly(MEA)test suggests than only 2.18 V is required to achieve a current density of 5 A/cm^(2).The theoretical calculation reveals that the e_(g)filling of Ru atom is increased from 2.18 to 2.39 after MnO_(2)incorporation,reducing the energy for the formation of∗OOH moiety.

We proposed new methods of switching 3D images using projectors for moving images on an arc 3D display. An arc 3D display is a 3D display method that uses directional scattering of light generated by arc-shaped scratches on a substrate, but rewriting the displayed 3D images is difficult by conventional arc 3D displays. In this study, we proposed a method of switching the 3D images by selectively illuminating the arc-shaped scratches using a projector. In order to present arbitrary 3D images, we also proposed a method of displaying multiple depths by arranging the arc-shaped scratches in a grid pattern and illuminating them at different angles using multiple projectors. Furthermore, we proposed a method to avoid intersections of arc-shaped scratches by using Fresnel-type scratches, and proposed an optimal pixel arrangement for this method, and confirmed its effectiveness. © 1972-2012 IEEE.

Natural dyes serve as a benign alternative to their synthetic counterparts, offering a sustainable option that directly mitigates the release of toxic chemicals. In this study, cotton fabrics were dyed with neem leaf extract in acidic, neutral and alkaline condition where samples were mordanted with lemon juice. The findings revealed a direct correlation between colour strength (K/S) and pH levels, and optimal fastness properties were achieved under alkaline pH conditions when a mordant was employed. The Energy Dispersive X-ray (EDX) ensured the elemental composition of lemon juice assisted dyed fabric which indicates the effective binding of cotton fabric with neem leaves extracted dye. The Fourier Transform Infrared (FTIR) Spectroscopy analysis also confirmed the interaction of cotton fabric with dye particles. The results indicate that cotton fabric can be successfully dyed with neem leaf extract and lemon juice as the biomordant, presenting an eco-friendly and sustainable approach to dyeing practices. © 2024 Informa UK Limited, trading as Taylor & Francis Group.

We derive the exact expression for the resonant frequency of the time-averaged steady-state energy and show that this frequency is excellently approximated by the arithmetic mean of the amplitude and velocity resonant frequencies. In addition, we argue that the frequency of the amplitude resonance can be regarded as the energy resonance frequency, since it provides the maximal peak values of instantaneous energy. © 2025, CC BY.

Fabrication of a polycarbonate/polypropylene fiber mix air filter using a melt-blowing apparatus with different nozzle diameters

Air filter filtration efficiency is determined by the particle capture-to-pressure drop ratio. We produced a melt-blown nonwoven fabric with a specific fiber diameter distribution by blending thick fibers using nozzles with different diameters. When a polycarbonate was extruded from large holes, the particle transmittance rate doubled and the pressure drop decreased by 1/3. Consequently, the quality factor increased by 1.5-fold. Most of the fibers in a pure polypropylene sample had diameters below 20 µm, even when the polypropylene was extruded from large holes. However, when polycarbonate was extruded, the distribution widened to 40 µm, and the proportion of fibers in the 20‒40 µm range increased. The pore size distribution followed a similar tendency of fiber distribution. Analysis of the fibers with diameters above 20 µm revealed that the fiber volume fraction widened markedly in the thickness direction. That is, a greater number of thick fibers ensures more air passages, thereby decreasing the pressure drop. The thick fibers form large pores, which increases the length of the flow paths of the aerosols. This increases the probability of particles contacting the fibers and suppresses particle penetration. The changes described above explain the increase in the quality factor. © 2025 The textile Machinery Society of Japan.

Stab-resistant textiles play a critical role in personal protection, necessitating a deeper understanding of how structural and layering factors influence their performance. The current study experimentally examines the effects of textile structure, layering, and ply orientation on the stab resistance of multi-layer textiles. Three 3D warp interlock (3DWI) structures ({f1}, {f2}, {f3}) and a 2D woven fabric ({f4}), all made of high-performance p-aramid yarns, were engineered and manufactured. Multi-layer specimens were prepared and subjected to drop-weight stabbing tests following HOSBD standards. Stabbing performance metrics, including Depth of Trauma (DoT), Depth of Penetration (DoP), and trauma deformation (Ymax, Xmax), were investigated and analyzed. Statistical analyses (Two- and One-Way ANOVA) indicated that fabric type and layer number significantly impacted DoP (P 0.05). Further detailed analysis revealed that 2D woven fabrics exhibited greater trauma deformation than 3D WIF structures. Increasing the number of layers reduced both DoP and DoT across all fabric structures, with f3 demonstrating the best performance in multi-layer configurations. Aligned ply orientations also enhanced stab resistance, underscoring the importance of alignment in dissipating impact energy. © 2025 China Ordnance Society

Conductive hydrogel has garnered significant fascination for its potential as wearable sensor. However, designing a wearable sensor with excellent electrical conductivity, self-healing capability, mechanical strength and recyclability is still difficult to accomplish. Herein, a multifunctional composite hydrogel was fabricated via a one-pot method with cellulose microcrystals (CMCs) and MXene. The introduction of CMCs to the hydrogel composite provided mechanical strength and assisted in homogeneous distribution of MXene resulting the high electrical conductivity. The subsequently prepared conductive composite hydrogel exhibited improved tensile strength (87.4 kPa) and elongation at break (424 %) with optimum composition, outstanding electrical conductivity (1.11 S/cm) and quick electrical self-healing efficiency without external stimuli. The temperature responsiveness of the conductive composite hydrogel was mainly accredited for reducing interfacial thermal resistance ensuing of continuous heat conduction pathways. It also demonstrated the notable fire resistance offering quick fire-warning signals within ∼1 sec. The developed conductive composite hydrogel could monitor subtle human movements efficiently as well as possessed the ability to track human body temperature, indicating effective means of electronic skin (E-skin) for smartphone interfacing. This work introduces a feasible approach in designing an electrically conductive, biodegradable wearable composite hydrogel with potential applications as versatile motion, temperature and fire sensor. © 2025 The Authors
