Nanopores are extremely sensitive single-molecule sensors. Recently, electron beams have been used to fabricate synthetic nanopores in thin solid-state membranes with subnanometer resolution. Here we report a new class of chemically modified nanopore sensors. We describe two approaches for monolayer coating of nanopores: (1) self-assembly from solution, in which nanopores approximately 10 nm di...

The microstructure and mechanical properties of 7075 wrought aluminum alloy produced by strain induced melt activation (SIMA) route were investigated.Also liquid volume fraction measurement was studied by three procedures. Remelting process was carried out in the range of 560 to 610 °C for 20 min holding. The microstructure in the semi-solid state consists of fine spherical solid grains surroun...

Distinct affinities between the organic and inorganic phases were observed in nanocomposites prepared through a colloidal route with carboxylated nitrile rubber and modified silica nanoparticles, which resulted in variable mechanical properties and improved thermal stability. Nanoparticles with modified surface affected the macromolecular arrangements of the elastomeric matrix, changing the fin...

One-dimensional (1D) coordination polymer, [Zn(4,4´-bpy)(H2O)4](ADC).4H2O (1) (4,4´-bpy = 4,4´-bipyridine and H2ADC = acetylenedicarboxylic acid), and three-dimensional (3D) metal-organic framework (MOF), Zn(ADC)2.(HTEA)2(2) (HTEA = triethylamine) were prepared at room temperature. The compounds were characterized by single-crystal X-ray diffraction and powder X-ray diffraction (PXRD) analyses....
