Abstract Graphene has superhigh thermal conductivity up to 5000 W/(m·K), extremely thin thickness, mechanical strength and nano-lamellar structure with low interlayer shear strength, making it possess great potential in minimum quantity lubrication (MQL) grinding. Meanwhile, ionic liquids (ILs) have higher better stability than vegetable oils, which are frequently used as MQL grinding fluids. A...

Abstract Nanofluid minimum quantity lubrication (NMQL) is a green processing technology. Cottonseed oil suitable as base because of excellent performance, low freezing temperature, and high yield. Al 2 O 3 nanoparticles improve not only the heat transfer capacity but also performance. The physical chemical properties nanofluid change when are added. However, effects concentration on performance...

Directly compressible co-processed sustained release multifunction agent [DCCSRA] comprising povidone and glyceryl behenate in the ratio of 1:1, 1:2 and 1: 3 were prepared and evaluated. The DCCSRA exhibited good flow and compressibility. The DCCSRA served as a retardant, binder and lubricant in Gliclazide sustained release tablets. By optimization of DCCSRA quantity in formulation, the drug re...

Given an edge-distance graph of a set of suppliers and clients, the bottleneck problem is to assign each client to a selected supplier minimizing their maximum distance. We introduce minimum quantity commitments to balance workloads of suppliers, provide the best possible approximation algorithm, and study its generalizations and specializations. © 2005 Wiley Periodicals, Inc.
