One 3D Cu(II)-based metal-organic framework {[Cu3(tmpa)2(1,2,3-btc)2(H2O)2].14H2O.2DMF}n (Cu(tmpa)) (tmpa ​= ​tris(4-(2-methyl-1H-imidazole-1-yl)phenyl)amine, 1,2,3-H3btc ​1,2,3-benzenetricarboxylic acid) was prepared by hydrothermal method and characterized. Cu(tmpa) exhibits (3,3,4)-connected topology showing point symbol of (6·8·9)2(6·8·10)2(62·82·102). The heterostructural Cu(tmpa)/CN compo...

A valveless electromagnetic (EM) micropump with a matrix-patterned magnetic polymer composite actuator membrane structure was successfully designed and fabricated. The composite membrane structure is made of polydemethylsiloxane (PDMS) that is mixed with magnetic particles and patterned in matrix blocks. The matrix magnetic composite membrane was fabricated using a soft lithography process and ...

Flywheel systems based on fibre composites can have power densities which are significantly better than for electrochemical batteries. Hence, they have considerable potential for use as peak power buffers in drive-trains for electric and hybrid vehicles. As the rotational speed is increased, however, bearing friction power loss and iron losses in the motor/generator become more significant. Thu...

The freshness and quality indices of whiting (Merlangius merlangus) influenced by a large number of chemical volatile compounds, are here analyzed in order to select the most relevant compounds as predictors for these indices. The selection process was performed by means of recent statistical variable selection methods, namely robust model-free feature screening, based on quantile correlation a...

Effects of abrasive and fiber components in a medium on the wear behavior of composite resins were evaluated. Calcium diphosphate and methyl cellulose were included in the medium as abrasive and fiber components respectively. A range of 0, 4, or 8% abrasive- or fiber-containing media were applied on a composite resin specimen during a simulated occlusal wear test. Four composite resins, Clearfi...

objectives: dental composite wear in posterior restorations is a concern and is affected by different factors. this study was conducted to evaluate the effect of polishing and mechanical loads on wear of silorane-based and methyl methacrylate-based composites resins. materials and methods: of each dental composite (filtek p90 and filtek p60), 40 samples were fabricated in a polyethylene mold (4...

A hybrid composite based on metal-organic framework (MOF) was chemically fabricated by embedding the magnetic Fe3O4 nanoparticles within amino-functionalized porous La-MOF (MOF/NH2) to produce a highly efficient and reusable of MOF/NH2/Fe3O4. Different proper techniques were used for characterization surface morphology chemical arrangement prepared MOF/NH2/Fe3O4 composite. The results using var...

We present a microfluidic-based method allowing for the controlled production of lipid particles with encapsulated magnetic nanoparticles (MNPs). Within the same device, the magnetic properties of the composite particles are tested as they flow downstream. The effect of the fluid properties and flow parameters on the size of the microparticles containing MNPs is studied using standard flow visu...
