Research of X-ray induced conductivity of ZnSe sensors for their application in isotopic thickness gauges [PDF]
Radiation Measurements, Vol. 46, No. 5-7, 2011 (under review,
manuscript number: "RADMEAS-D-11-00134"), 2011 Measurements of intrinsic conductivity and X-ray induced conductivity were performed on specially undopped ZnSe samples. The measurements demonstrated that sensors made of ZnSe have minor intrinsic conductivity when heating up to the temperature of 180 {\deg}C, and significant X-ray induced conductivity.

A MEMS Electromagnetic Vibration Energy Harvester with Monolithically Integrated NdFeB Micromagnets
Advanced Materials Technologies, EarlyView.50µm thick sputtered arrays of NdFeB micromagnets are directly integrated into a functional MEMS in‐plane electromagnetic vibration energy harvester. A combination of analytical modeling and numerical simulations guided the design of the magnet arrays and ad‐hoc coil, to produce a high transduction factor.

Application Areas of Ionic Hydraulic Fluids
Chemical Engineering &Technology, Volume 46, Issue 1, Page 14-20, January 2023., 2023 Ionic liquids as high‐tech technical fluids have also made their way into the field of hydraulic drives. With excellent lubricating properties, a wide temperature range, low pour point and vapor pressure, as well as nonflammability and environmental suitability, problems with only one type of fluid, namely, an ionic hydraulic fluid, instead of using ...

Effect of an electric field on a Leidenfrost droplet [PDF]
Soft Matter 8 (22) 5992 (2012), 2012 We experimentally investigate the effect of an electric field applied between a Leidenfrost droplet and the heated substrate on which it is levitating. We quantify the electro-Leidenfrost effect by imaging the interference fringes between the liquid-vapour and vapour-substrate interfaces.

Advanced Materials Technologies, EarlyView.This work demonstrates fluidic self‐assembly and self‐alignment of flip‐chips using a magnetic field for agitation and orientation. Pb‐free solder bumps with tailored transformation imprinted melting points enable selective capturing on low‐melting solder in water. After capturing, final alignment is achieved through magnetic forces.

Chemical Engineering &Technology, Volume 46, Issue 1, Page 110-117, January 2023., 2023 In hydraulic axial piston pumps, conventionally leaded brass is used right against steel. In order to renounce lead and find a lead‐free alternative, high‐speed laser material deposition is employed to apply a carbide‐reinforced anti‐wear coating. Based on the experiences of prior tests, it demonstrates that this coating also works in a state‐of‐the ...

Line-Constrained Geometric Server Placement [PDF]
Metalurgia International, vol. 16, no. 11, pp. 106-110, 2011.
(ISSN: 1582-2214), 2013 In this paper we present new algorithmic solutions for several constrained geometric server placement problems. We consider the problems of computing the 1-center and obnoxious 1-center of a set of line segments, constrained to lie on a line segment, and the problem of computing the K-median of a set of points, constrained to lie on a line.
