A horizontal hermetic scroll compressor has been developed for applications with high heatof-compression gases, including natural gas, air and helium (cryogenics). The compressor is a low profile horizontal design with oil-flooded cooling of the compression process. Combined with components required for oil separation and cooling, this design provides a smooth, continuous compression process fe...

Marine pollution caused by frequent oil spill accidents has brought about tremendous damages to marine ecological environment. Therefore, the facile large-scale preparation of three-dimensional (3D) porous functional materials with special wettability is in urgent demand. In this study, we report a low-cost and salt-tolerant superoleophobic aerogel for efficient oil/seawater separation. The aer...

The present work was designed to study the antioxidant activity and to identify the main active components of the essential oil of ajowan (Trachyspermum copticum) fruit. GC and GC-MS analyses of the essential oil showed the presence of eight compounds. The main constituents of the oil were thymol (43.7%), p-cymene (26.8%), and γ-terpinene (24.9%). The antioxidant and free radical scavenging act...

Due to their extraordinary prospective uses, particularly in the areas of oil–water separation, underwater superoleophobic materials have gained increasing attention. Thus, artificial nacre has become an attractive candidate for separation due its superhydrophilicity and superoleophobicity properties. Synthesized successfully achieved a high mechanical strength that is close or even surpasses n...
