Improving the mechanical stability and anti-corrosion durability of superhydrophobic material remains agreat challenge that has not been solved. In this paper, we designed and prepared two types of superhydrophobiccoatings using PTFE nanoparticles and waterborne epoxy resin, viz. superhydrophobicPTFE@epoxy single layer coating and superhydrophobic Epoxy + PTFE@epoxy double layer coating. Itwas found that the mechanical stability and interfacial bonding of the superhydrophobic composite coatingswere further improved by introducing an epoxy resin intermediate layer. The superhydrophobicEpoxy + PTFE@epoxy double layer coating maintained excellent non-wetting superhydrophobicity evenafter 150 sandpaper abrasion and 160 tape-peeling cycles. The electrochemical testing results showedthat the Rct and low-frequency modulus values of the superhydrophobic double layer coating improvedby 7–8 orders of magnitude compared with the bare Q235 carbon steel substrate, demonstrating excellentcorrosion resistance. In addition, the coating maintains good corrosion protection after 60 days ofoutdoor atmospheric exposure and 30 days of neutral salt spray acceleration tests, indicating superiorweathering resistance and long-term anti-corrosion properties. The coating also features delayed icing,self-cleaning, anti-fouling, chemical stability, and high substrate applicability, which provides longlastingmultifunctional superhydrophobic materials with comprehensive functions.

A novel method for the preparation of Mn-containing silylated layered double hydroxides (LDHs) ispresented. The method involves functionalizing the calcined MgAl LDH (LDO) with dimethoxydiphenylsilane(DDS), and then treating it in the aqueous solution of KMnO4 under Ar. The prepared Mncontainingsilylated MgAl LDH catalysts have higher Mn amount and more accessible Mn sites than thecorresponding Mn-containing MgAl LDH catalysts, and exhibited much higher catalytic activity in theoxidation of ethylbenzene with O2 in the absence of organic solvents than the latter. In addition, theprepared Mn-containing silylated MgAl LDH catalyst was highly stable and reusable.

Electrospun SrO-Incorporated Nanofiber Membranes for Biomedical Applications
Zhe Chen,Jitao Fan,Yangfan Ding,Yunlong Zhang,Ahmed I. Abd‑Elhamid,Jinglei Wu,Binbin Sun 한국섬유공학회 2023 Fibers and polymers Vol.24 No.11
Bioactive ceramics have gained increasing interest in biomedical applications. Strontium (Sr)-based ceramics show unique bioactivity in stimulating cell proliferation and migration and promoting angiogenesis. Incorporation of bioactive ceramics into nanofibers represents a facile approach to alter the material properties of electrospun nanofiber membranes. Herein, we prepared SrO-incorporated nanofiber membranes by electrospinning and investigated the effects of SrO particles on the physicochemical properties and cytocompatibility of these membranes. Our results indicate that simple one-stream electrospinning could smoothly introduce SrO particles into poly(L-lactic acid) (PLA)/gelatin nanofibers. SrO-incorporated membranes showed significantly improved wettability but became brittle compared with PLA/gelatin nanofiber membranes. Cells differentially responded to SrO-incorporated membranes: endothelial cells showed greater cell area and coverage on SrO-incorporated membranes; in contrast, fibroblasts were inhibited on these membranes. These findings suggest that SrO-incorporated membranes might find opportunities in specific biomedical applications in which pro-angiogenesis and antiadhesion are simultaneously demanded.

Ultrasonic vibration assisted grinding (UVAG) is an effective method for edge trimming to improve the mechanical integrity of carbon fiber reinforced polymer (CFRP). However, due to the high heat resistance, abrasiveness and powdery chip of CFRP, serious tool clogging, rapid tool wear and poor surface are still considerable problems to the industry. In this paper, monolayer brazed diamond grinding tools with defined grain distribution are designed in order to solve the above problems. The maximum undeformed chip thickness based on UVAG was analyzed. A mathematical grinding force model was established based on monolayer brazed diamond tools. The UVAG experiments using different grain inter-row spacing diamond tools were carried out. The grinding force and surface morphology were investigated and compared. It was found that the predicted grinding force values were consistent with the experimental results. Additionally, the force was strongly related to the grain inter-row spacing. When employing the tool with the grain inter-row spacing of 1.2 mm, the grinding force was highest and the roughness of the surface was better due to more active grits and interaction-overlap areas.

THERMAL COMFORT OF AUTOMOBILE DRIVER BASED ON LOCAL AIR CONDITIONING VENT ARRANGEMENT
Chen Suifan,Xue Dong,Li Qipeng,Du Binbin,Fan Xilei 한국자동차공학회 2023 International journal of automotive technology Vol.24 No.4
When there is only one person in the car, the traditional air conditioning vent arrangement of the car will cool the whole cabin, which is a waste of energy. A new local air conditioning vent arrangement has been studied to solve this problem. Two local air inlet arrangements, namely the ceiling independent air inlet arrangement and the top and bottom mixed air inlet arrangement (case 5) were proposed, mixed air inlet arrangement is ceiling and floor air discharge from air-conditioner respectively, and four air inlet schemes were designed for the ceiling independent air inlet arrangement. At the same time, the thermal comfort of the driver is studied based on different inlets position, by using the CFD simulation method and according to the thermal comfort evaluation standard of equivalent temperature. The results show that although the ceiling inlet arrangement solves the problem of high energy consumption, it cannot meet the thermal comfort needs of driver. In the mixed inlets arrangement, the air velocity of the driver is between 0.13 ~ 0.6 m/s, the air temperature distribution range around the driver is 21.2 ~ 27.8 deg.C and the equivalent temperature curve is in the thermal neutrality zone, which can meet the thermal comfort requirements of the driver.
