Slip-Effect Functional Air Filter for Efficient Purification of PM2.5
Fabrication of air filtration materials (AFM) that allow air to easily flow through while retaining particles is a significant and urgent need due to the harmful airborne particulate matter pollution; however, this is still a challenging research area. Herein, we report novel slip-effect functional nanofibrous membranes with decreased air resistance (reduction rate of 40%) due to the slip flow ...
متن کاملA Regenerable Filter for Liquid Argon Purification
A filter system for removing electronegative impurities from liquid argon is described. The active components of the filter are adsorbing molecular sieve and activated-copper-coated alumina granules. The system is capable of purifying liquid argon to an oxygen-equivalent impurity concentration of better than 30 parts per trillion, corresponding to an electron drift lifetime of at least 10 ms. R...
متن کاملThe viability of photocatalysis for air purification.
Photocatalytic oxidation (PCO) air purification technology is reviewed based on the decades of research conducted by the United Technologies Research Center (UTRC) and their external colleagues. UTRC conducted basic research on the reaction rates of various volatile organic compounds (VOCs). The knowledge gained allowed validation of 1D and 3D prototype reactor models that guided further purifi...
متن کاملNarrowing Microfluid Width In Microchannel Using Air Boundaries
A novel method for narrowing microfluid width in microchannel is presented by utilizing of air boundaries of which inflation direction is perpendicular to microfluid flow. The air boundaries are generated by heating water with microheater. The microfluid width of 300 pm can be focused and maintained as up to 22 pm which is near cell size without affecting cell or microchannel structure. The nar...
متن کاملR-410A Air Conditioning System With Microchannel Condenser
This paper presents experimental results from a prototype of a microchannel heat exchanger used in a residential air-conditioning system as an air-cooled condenser. The main objectives were to analyze effects of the microchannel condenser on system performance. The commercially available system that utilizes a condenser with a round tube and plate fins was experimentally evaluated first, then t...
