Thermoregulatory clothing plays an indispensable role in maintaining body thermal comfort and achieving building energy savings response to fluctuating ambient. Existing temperature-adaptive without external input has very limited thermoregulatory power because of the lack simultaneous regulation multiple heat-dissipation pathways. Here, we report with multimodal body-heat (viz. convection, radiation, sweat evaporation), which can automatically adapt temperature change (15°C–35°C) within...
Abstract We report tip-multi-breaking (TMB) mode of droplet breakup in capillary microfluidic devices. This new appears a region embraced by Ca i = 0 and lg( ) − 8.371( −7.36 with varying from 0.35 to 0.63 on the – phase diagram, being numbers inner outer fluids, respectively. The is featured periodic, constant-speed thinning liquid tip periodic formation sequence droplets. number n determined increases varies two over ten. distribution both pinch-off time size droplets geometric progression...
Passive regulation of liquid transport in porous media a directional or asymmetric manner has become increasingly critical to emerging applications, such as personal moisture management, water harvesting, and separation. Over the past decade, heterogeneously engineering materials structures for tunable triggered technological revolutions those areas based on nature-inspired design, metamaterial development, model-driven optimization. Herein, we discuss latest developments movement created by...
A photothermal nanoconfinement reactor (PNCR) system is proposed and demonstrated by using hollow carbon nanospheres (HCNs) to enhance the performance of chemical reaction. Under light irradiation, local temperature HCN inner void space was much higher than bulk solution because confined concentrates heat inhibits loss. Using temperature-sensitive model reaction, peroxydisulfate (PDS) activation oxidize micropollutant, it shown that degradation rate sulfamethoxazole in PNCR 7.1 times without...
Acting as the interface between human body and its environment, clothing is indispensable in thermoregulation even survival under extreme environmental conditions. Development of textiles with prolonged passive temperature-adaptive without external energy consumption much needed for protection from thermal stress saving, but very challenging. Here, a filament (TATF) consisting thermoresponsive vacuum cavities formed by temperature-responsive volume change material confined cellular cores...
Aiming at problems such as the low efficiency of renewable energy conversion and single flow mode, this paper proposes a heat pump storage system combining cold, power generation to achieve purpose diversified utilization energy. The is suitable for buildings requiring cooling, heating/domestic hot water production electricity. This mainly uses MATLAB numerical calculations, selects several key cycle parameters calculate analyze thermodynamic performance system, genetic algorithm TOPSIS...
Abstract Soft heat pipes are vital in many applications. Inspired by the structure of a squid, we proposed squid‐like soft pipe with multiple transport branches that has excellent flexibility and outstanding thermal performance. Each branch could to different locations for heating or cooling The worked as pulsating unidirectional flow liquid slugs vapor bubbles. Its performance was investigated at temperatures, bending angles, inclination angles. result showed highest equivalent conductivity...
Abstract We investigate the influences of expansion-contraction microchannels on droplet breakup in capillary microfluidic devices. With variations channel dimension, local shear stresses at injection nozzle and focusing orifice vary, significantly impacting flow behavior including locations modes. observe transition location from to three distinct types recently-reported tip-multi-breaking By balancing interfacial tension effects, we determine critical condition for characterize mode...
The energy consumption for maintaining desired indoor temperature accounts 20% of primary use worldwide. Passive rooftop modulation solar/thermal radiation without external input has a great potential in building saving. However, existing passive techniques failed to simultaneously modulate response surface which is closely related the thermal loads, leading limited or even counter-productive overall Here, we report development temperature-adaptive covering with synergetic solar and...
