A fluorine-free and multifunctional superhydrophobic coating(r-MSC)was prepared by the one-step spraying method.The coating had superhydrophobic and low-adhesion properties with the water contact angle of 161.5°�1°and the sliding angle of 3.2°�0.5°.It could be prepared by spraying while maintaining superhydrophobic surface characteristics on any substrates.The coating owed outstanding mechanical durability and chemical stability.Moreover,the coating also possessed the ability of self-cleaning,anti-fouling,anti-icing,and flame retardant ability.Importantly,the presence of multifunc-tional coating endowed the substrate with both water-resistant and fireproof properties.Besides,it also showed excellent oil-water separation ability,which presented the oil-water separation efficiency of over 90%for different types of oils after 10 separation cycles.Furthermore,the coating could improve corrosion inhibition performance and the corrosion current density was reduced by two orders of magnitude from the polarization curve.The r-MSC had the advantages of simple preparation,fluorine-free,environ-mentally friendly and appropriate for large-area fabrication,which could be applied to various fields.

This article describes a method for synthesizing an excellent oil soluble calcium isostearate detergent using isostearic acid and calcium hydroxide as main starting materials. Reaction conditions, including the molar ratios of calcium hydroxide to isostearic acid, methanol to calcium hydroxide and water to calcium hydroxide, the carbonation temperature, the CO_2 flow rate, and the volume of injected CO_2, were optimized. Under the optimized conditions, a high alkalinity calcium isostearate detergent with a total base number(TBN) of 358 mg KOH/g and an overbased calcium isostearate detergent with a value of TBN equating to 406 mg KOH/g could be obtained. Finally, the properties of the calcium isostearate detergent were evaluated by the size distribution analysis, the thermogravimetric analysis(TGA) and the coking tendency tester.

Behind Qatar's green promise as the first"carbon neutral"World Cup is the use of a large amount of renewable energy and environmentally friendly materials to facilitate the recycling of materials after the event.The Stadium 974,one of the World Cup venues,is the first fully removable,mobile and reusable"Green Stadium"in World Cup history,constructed from 974 large shipping containers made of recycled steel.After the World Cup,the 40,000-seat temporary stadium has been dismantled and all the containers,along with removable seats inside the stadium,have been donated to countries in need.

A new type of environmentally friendly lube additive-amide type modified rapeseed oil was synthesized and characterized by infrared spectrum. Its effect on the friction and wear behavior of steel-steel and steel-aluminum alloy systems were investigated with a four-ball machine and an Optimol SRV friction and wear tester respectively.The morphographies of the worn surfaces were analyzed by means of scanning electron microscopy(SEM). The worn surfaces of the 2024Al alloy block were analyzed by means of X-ray photoelectron spectroscopy(XPS). The results show that the modified rapeseed oil as additives can obviously decrease the wear rate and friction coefficient of steel pair and steel-aluminum frictional pair. Its lubrication mechanism is inferred that a high strength complex protection films form on the worn surface of the Al alloy due to the adsorption or tribochemistry reaction of a long chain additive molecule and high reaction activity of N element.
