This paper introduces the concept of the Neutron Silicon Lens (NSL) and provides and update on the experimental results achieved to date. The NSL design is a cylindrical neutron lens based on the use of multiple neutron mirrors supported and separated by silicon wafers. Such lenses would have many applications in both the primary and scattered beams on neutron instruments, and would lead to imm...

Novel amphiphilic polyesters with both hydrophilic and hydrophobic functionalities being alternately distributed along polymer backbones have been synthesized and characterized. The polyesters are soluble in organic and aqueous media and reveal the formation of inverse architectures whose behavior could be correlated to their chemical structure. This work offers a new approach to building up se...

The possibility of a wide range adjustment the hydrophilic-hydrophobic properties silicon wafers is demonstrated by means treatment with hydrofluoric acid, Caro's and various concentrations hydrogen peroxide solutions. By measuring contact angles wetting calculating total, polar, dispersive components surface energy, it has been found that most significant hydrophilization as well maximum incre...

Electrochemical experiments were conducted on {100}, {110}, and {111} silicon wafers to characterize the kinetics of the initial lithiation of crystalline Si electrodes. Under constant current conditions, we observed constant cell potentials for all orientations, indicating the existence of a phase boundary that separates crystalline silicon from the amorphous lithiated phase. For a given poten...

Silicon microcombs developed at our laboratory for the precision alignment and assembly of large-area foil optics have previously been demonstrated to achieve submicron-level assembly repeatability with submillimeter-thick flat substrates. In this article we report on a double-side deep reactive-ion etch fabrication process using silicon-on-insulator wafers which was developed to improve the mi...
