Silicon nitride–zirconia–graphene composites with high graphene content (5 wt.% and 30 wt.%) were sintered by gas pressure sintering (GPS). The effect of the multilayer (MLG) on microstructure fracture mechanism is investigated multi-scale in-situ microscopy. Multi-scale microscopy confirms that phases disperse evenly in without obvious agglomeration. MLG flakes well dispersed between ceramic m...

PURPOSE To compare the efficacy between macular laser grid (MLG) photocoagulation and MLG plus intravitreal triamcinolone acetonide (IVTA; MLG+IVTA) therapy in diabetic macular edema (DME) patients. METHODS A prospective, randomized, clinical trial was conducted of DME patients. A total of 60 eyes (54 patients) affected by DME were observed for a minimum of 6 months. Thirty eyes of 28 patient...

The mixed-linkage (1→3),(1→4)-d-glucan (MLG) specific glycosyl hydrolase lichenase is an important biochemical tool for the structural characterization of MLGs. It holds potential for application in the brewery, animal feed, and biofuel industries. Several defined MLG oligosaccharides obtained by automated glycan assembly are used to analyze the substrate specificities of Bacillus subtilis lich...

To distinguish the strengthening effect of multilayer graphene (MLG) on copper matrix from intrinsic grain boundary (GB), nanoindentation behavior in Cu/MLG interface (IB) region is investigated and further compared with those GB pure interior (GI) regions. The indentation displacement recovery ratio, elastic work hardness IB regions are significantly enhanced as GI can be attributed to during ...

Self-lubricating composites are designed to obtain materials that reduce energy consumption, improve heat dissipation between moving bodies, and eliminate the need for external lubricants. The use of a solid lubricant in bulk composite material always involves a significant reduction in its mechanical properties, which is usually not an optimal solution. The growing interest in multilayer graph...

The effects of multi-layer graphene (MLG) on the properties tungsten carbide-11 cobalt (WC-11Co) cemented carbides were studied by transmission electron microscopy (TEM), scanning (SEM), X-ray diffraction analysis (XRD) and other methods. results show that when MLG content is 0.1 wt%, density, hardness fracture toughness are 3%, 14.5% 71.8% higher, respectively, compared with sample without MLG...

abstractbackground and objective: microwave-assisted extraction (mae) is one of the novel, fast, and efficient methods for extraction of bioactive compounds. the aim of this study was optimization of mae of betalains from red beet (beta vulgaris) and evaluating antioxidant activity of its methanolic extract.materials and methods: the effects of independent variables namely, microwave power leve...

The classical malachite green (MLG) assay of phosphate, which added MLG after molybdate to the acidified reaction solutions of phosphate, tolerated interference from papaverine, sildenafil, and some similar hydrophobic amines. Resonance Rayleigh scattering signals, the alleviation of interference by poly(vinyl alcohol), and the precipitation of some yellow complexes supported that the irreversi...
