Graphene oxide (GO) membranes hold promise for selective CO2 adsorption over N2 due to their carboxyl groups, making them attractive flue gas capture. However, challenges such as limited content, flexible nanosheets, and dense layer stacking hinder N2/CO2 selectivity, pressure resistance, permeability. In this study, we introduce a specific sub-nanometer framework structure within GO by in-situ growing ZIF-8 nanocrystals. This novel approach, achieved through simultaneous infiltration of...
The friction and wear behavior of Ag-2.5Cu-8MoS2 composite is investigated in this article. Wear tests were conducted against the coin silver under a range sliding loads from 1 to 4 N distances 15 km. loss increased linearly with load distance. coefficient reached constant value after short MoS2 lubricating films formed on worn surfaces transfer layer led low coefficient. Fine particles smeared debris observed detailed studies. concentration surface was about four times higher than that...
Abstract As the volume of natural draft wet cooling towers (NDWCTs) continues to increase, influence ambient air on thermal performance NDWCT is not clear. Therefore, main parameters such as gas–water ratio, circulating water temperature difference, and heat transfer in each zone were calculated, field humidity also investigated. The results showed that had greatest capacity increase led difference decreases most, which was 7.63 °C (74.15%). relative atmospheric pressure an convective...
Dopamine modified peanut husks (PH/DA), a novel adsorbent, were investigated to enhance the adsorption capacity of dyes (neutral red, NR and crystal violet, CV) fluoroquinolone antibiotics (ofloxacin, OFLX enoxacin, ENO). Scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared (FT-IR), thermo-gravimetric analysis differential scanning calorimetry (TG-DSC) Brunauer-Emmett-Teller (BET) method used characterize PH PH/DA. The findings demonstrated that physical...
Diacetoxy-stearoyloxy-titanium-modified graphene oxide (Titanate-GO) was successfully prepared using titanium tetraisopropanolate, stearic acid, acetic and (GO). The morphology structure of the as-prepared materials were tested by FT-IR, Raman, TG/DSC, SEM, TEM instruments. results indicate that long alkyl chains have been grafted on surface a GO sheet, which guaranteed dispersibility Titanate-GO in PAO10 base oil. Then, lubrication properties as lubricating additive oil evaluated four-ball...
Silver–copper/molybdenum disulfide (Ag-Cu/MoS2) composites, prepared by powder metallurgy and hot press sintering, were extruded at a temperature of 680°C with extrusion ratios 10 70. Mechanical tests tribotests carried on both the hot-pressed hot-extruded composites. The tribological properties composites against silver coin disc investigated pin-on-disc tester normal load sliding speed 5 N 0.27 m/s, respectively. microstructure, wear morphology, cross section worn subsurface observed...
The different microstructures of silver–copper/molybdenum disulfide (Ag-Cu/MoS2) composites were manufactured by hot press and extrusion processes to investigate the electrical tribological behaviors both hot-pressed hot-extruded under air vacuum. results showed that properties Ag-Cu/MoS2 improved extrusion, which decreased wear rates rapidly in In air, could improve transfer layer tribofilm, resulting a significant decrease contact voltage drop, goes from more than 70 mV composite 30 at...
The parallel connection of multiple flexible rings in raceways can significantly improve the electrical conductivity rolling conductive devices. Multiple are generally separated by idlers to form ring-idler pairs. In present work, alumina (Al2O3), polytetrafluoroethylene (PTFE), polyether ether ketone (PEEK), and polyimide (PI) were used as idler materials. Rolling tests for four types contact pairs carried out air at a rotating speed 10 rpm current 60 A. It was noticed that voltage drop...
This paper focuses on the extrusion process of powder/solid clad rods with desired hole ratio in center to reduce weight. The finite-element model about a lot deformation body was successfully demonstrated. Raw steel powder and tube were consisted as rods. While obvious plastic proceeding region, clearly lessened, then little rose apart from region. parameters determined for purpose lesson weight rod 15% experiment tensile property test proved that integrative improved while reduced. can be...
Selective laser melting (SLM), is a type of additive manufacturing, which selectively melts pre-spread layer metal powders and produce part by layer-on-layer manner.SLM has demonstrated great potential to reduce size weight in hydraulic manifolds.However, theoretical base lacking since friction loss unclear SLMed fluid passage.In this study, various passages without supports, from diameters 4 mm 16 mm, were produced horizontally using SLM.The profile was measured 3D scanner surface roughness...
