Actuating and Sensing Composites of Liquid Crystal Elastomers and Poly(ionic liquid)s

Advanced Functional Materials, EarlyView.
Ionic conductive, mechanically tough, flexible, and stretchable filaments of a composite material comprising a liquid crystal elastomer and a poly(ionic liquid) are produced through 3D printing, which exhibit large actuation strain under stimulation and electrical resistance variation in response to deformation or environmental condition changes. Their

ANALYSIS OF MECHANISM OF EXCITATION OF VIBRATIONS OF WORKING BODIES OF DISKATOR WITH ROTATION AROUND AXIS OF ATTACHMENT

Vibrations in engineering and technology, 2023
The paper proposes an analytical model of interaction with the ground of a spherical disk mounted on an elastic riser at angles to the direction of movement and vertical. The working hypothesis is that fluctuations in the elastic riser-disk system occur due to periodic changes in the components of the traction resistance.The model provides for the ...

Dispensing Volumetric Additive Manufacturing

Advanced Functional Materials, EarlyView.
Dispensing volumetric additive manufacturing (DVAM) prints 3D structures inside a photocurable resin droplet suspended from the tip of a glass pipette, enabling sequential printing without resin vats or manual part removal. Real‐time droplet profiling and ray‐tracing‐based correction compensate for optical distortion at the curved resin‐air interface ...

Statistically Resolving Thickness‐Dependent Electrical Characteristics in Multilayer‐MoS2 Transistors

Advanced Functional Materials, EarlyView.
A large number of MoS2 flakes were screened to obtain high‐quality flakes based on optical intensities in R, G, and B channel images. The flakes were classified from Level 1 to 6 based on optical intensities in the R, G, and B channel images. Low‐quality flake exhibited wrinkled, folded, or overlapped features, while high‐quality displayed a neat ...

Stability diagnosis of rotor-oil film bearing system by utilizing magnetic bearing

Nihon Kikai Gakkai ronbunshu, 2016
Oil film bearings are applied for large rotational machineries owing to their large load capacity and damping effect. However, a swirling flow of the lubricant induces self-excitation at high rotational speed.
