In few-layer graphene (FLG) systems on a dielectric substrate such as SiO2, the addition of each extra layer of graphene can drastically alter their electronic and structural properties. Here, we map the charge distribution among the individual layers of finite-size FLG systems using a novel spatial discrete model that describes both electrostatic interlayer screening and fringe field effects. ...

Layered Manufacturing processes accumulate residual stresses during material build-up. These stresses may cause part warping and layer delamination. This paper presents work done on investigating residual stress accumulation and part distortion of Layered Manufactured ar-tifacts. A simple analytical model was developed and used to determine how the number of layers and the layer thickness influ...

The method for assaying thymine-containing dimers in yeast is based on highly efficient ([3H]-deoxythymidine-5'-monophosphate) DNA-specific labelling and employs ascending thin layer chromatography. It allows satisfactory quantitative analysis down to UV-doses of 500 erg/mm2.

Purification by flash chromatography strongly impacts the greenness of a process. Unfortunately, due to the lack of the relevant literature data, very often this impact cannot be assessed thus preventing the comparison of the environmental factors affecting the syntheses. We developed a simple mathematical approach to evaluate the minimum mass intensity of flash chromatography from the retentio...

Cu(In,Ga)Se2 thin films (CIGS) on metallic substrate (titanium, molybdenum, aluminum, stainless steel) were prepared by a two-step selenization of Co-evaporated metallic precursors in Se-containing environment under N2 gas flow. Structural properties of prepared thin film were studied. To characterize the optical quality and intrinsic defect nature low-temperature photoluminescence, were perfor...

Nonlinear factors such as the contact stiffness and friction damping at threaded interface of a projectile–fuse system significantly affect dynamic response characteristics. To obtain fuse body accurately during penetration, it is necessary to characterize these nonlinear reasonably. Because existing structural dynamics software cannot effectively deal with factors, thin-layer element method wa...
