Extreme Gravity Fields and Equation of Gravity Field. Astrophysical Aspects
, 2019 A long enough interaction between a matter and a gravity field leads to considerable increase of the latter and to emergence of gravity field energy flux in the direction of matter acceleration. This is a direct consequence of the conservation law of energy-momentum.

Results in Physics, 2013 AbstractUsing computer algebra to run Einstein’s equations “backward”, from field to source rather than from source to field, we design an artificial gravity field for a space station or spaceship. Everywhere inside astronauts experience normal Earth gravity, while outside they float freely.

Advanced Materials, EarlyView.Spatiotemporal control over cell behavior within bioprinted constructs remains a key challenge in biofabrication. Volumetric bioprinting using multi‐wavelength light sources permits to activate light‐sensitive intracellular proteins as well as optogenetic gene and protein expression circuits in bioprinted cells, in addition to enabling fast printing of

The structure evolution and stability of NiW films electrodeposited under super gravity field
, 2010 The effect of super gravity field on the structure evolution of electrodeposited NiW films was studied. The results indicated that with the increase of gravity coefficient (G), W content in NiW films was increased and grain was refined.

Fast Hydrogel Micro‐Actuators Driven by Electric Fields
Advanced Materials, EarlyView.We report the fabrication of chemically programmable electroactuating microstructures through the first integration of two‐photon polymerization with electrically actuated gelatin methacrylate‐based hydrogels. By tailoring the charge of the polymer network, we demonstrate programmable polarity‐dependent bending, enabling microstructures that ...
