Strain Engineering of Complex Oxide Membranes on Flexible Metallic Support

open access: yesAdvanced Physics Research, EarlyView.
Integrating freestanding complex oxides on flexible platforms holds great promise for next‐generation electronics. The successful integration and adhesion of freestanding single‐crystalline La0.7Sr0.3MnO3 membranes onto metal‐coated polymer substrates (Au, Pt, TiN) is demonstrated.

Management of Lost Atherectomy Devices in the Coronary Arteries

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Rotational and orbital atherectomy are important tools to treat calcific coronary disease. Entrapment of an atherectomy device, that is, rotational atherectomy burr or orbital atherectomy crown, is a serious complication during atherectomy. Loss of an atherectomy device is a more challenging complication that usually follows device entrapment.

Laser vision correction among Kuzbass miners

open access: yesКлиническая практика, 2019
Background. In the structure of Kuzbass miners ophthalmopathology, disorders of refraction and accommodation occupy the first place. Excimer laser vision correction is the only acceptable method for correcting various refractive errors that allows miners

Transverse Optical Mode Patterns for an RF Excited Ar-He-Xe Laser [PDF]

open access: yes, 1999
Transverse optical modes for an RF excited Ar-He-Xe laser are studied both experimentally and theoretically. A diffraction model for a waveguide with a nonsaturable gain and refractive index gradients placed between two plane mirrors is formulated.
