Three-Dimensional Bioprinted Skin Microrelief and Its Role in Skin Aging [PDF]
Skin aging is a complex physiological process, in which cells and the extracellular matrix (ECM) interreact, which leads to a change in the mechanical properties of skin, which in turn affects the cell secretion and ECM deposition.

Synthesis of nano-optical elements for zero-order diffraction 3D imaging [PDF]
A method is proposed to compute and synthesize a microrelief to produce a new nano-optical element for forming 3D images with full parallax at the zero order of diffraction. The synthesis of nano-optical elements requires the use of multilevel structures.

Partially Regular Microreliefs Formed by Rotation
A new scheme for forming partially regular microreliefs by rotational rolling is proposed. A new transcendental curve-shaped, partially regular microrelief (of a trochoid type) is discussed; the shape and geometric parameters of its grooves are ...

Optimization of the parameters of a partially regular microrelief by vibration rolling method [PDF]
Experience of operating machines shows that their quality depends on the nature of the contact of mating parts. The irregular nature of the surface microrelief, which is due to traditional treatment methods used, arises difficulties in solving three main
