Advanced Engineering Materials, EarlyView.Binder‐free laser powder bed fusion of 8YSZ with a femtosecond laser is used to map process windows linking scan strategy, heat accumulation, and grain growth. Time‐resolved thermography and simulations reveal thermal regimes that enable continuous, vitrified, and fine‐grained 8YSZ surface layers without absorptive additives and demonstrate ...

Radio over fibre distribution systems for ultra-wide band and millimetre wave applications [PDF]
, 2011 Short range wireless technology such as ultra-wideband (UWB) and 60 GHz millimetre wave (mm-wave) play a key role for wireless connectivity in indoor home, office environment or large enclosed public areas.

Ionosphere disturbance during cosmodrome “Vostochniy” launches
E3S Web of Conferences, 2018 It is known that during spacecraft launches ionospheric plasma properties are modified in the result of impact of shock-acoustic waves generated during carrier rocket supersonic motion. As a rule, investigation of ionospheric plasma variations is carried

Dependence of the F2-layer critical frequency median at midlatitudes on geomagnetic activity
Solar-Terrestrial Physics, 2017 We put forward a method of separating the geomagnetic activity contribution to the F2-layer critical frequency median, foF2med, at middle latitudes. It is based on the analysis of foF2, which is the ratio foF2med/foF2q in percent, where foF2q is the F2 ...

Advanced Engineering Materials, EarlyView.To enhance through‐thickness conductivity without sacrificing impregnation, large spherical graphite particles are intentionally employed in a low‐viscosity resin. Unlike finer conductive fillers, these particles remain outside the fiber bundles and accumulate in resin‐rich interlaminar regions during molding.

Recurrent and sporadic Forbush decreases during solar cycles 23–24
Solar-Terrestrial Physics, 2019 A comparison has been made between recurrent (associated with high-speed streams from coronal holes) and sporadic (caused by interplanetary coronal mass ejections (ICMEs)) Forbush decreases (FDs) in solar cycles 23 and 24 (as well as in the maxima of ...

Laser‐Induced Graphene from Waste Almond Shells
Advanced Functional Materials, EarlyView.Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Deformation-Electromagnetic Relations in Lithospheric Activity Manifestations
E3S Web of Conferences, 2018 It has been shown that dipole radiation of accelerated charges, described by Larmor relation, is the basis of the known mechanic-electromagnetic processes of rock deformation.

Barometric effect of neutron component of cosmic rays at Antarctic station «Mirny»
Solar-Terrestrial Physics, 2016 The barometric effect of cosmic ray neutron component was estimated on the example of the Antarctic station Mirny. We used hourly data from continuous monitoring of neutron component and data from a local weather station for 2007–2014.
