Parameter Investigation for Stamp Manufacturing of Complex 3D Geometries Using Nanoimprint Lithography

open access: yesAdvanced Materials Technologies, EarlyView.
Nanoimprint lithography can replicate complex 3D microstructures with undercuts using single‐layer polymer stamps of different elasticities. By combining experiments and simulations, T‐shaped geometries and suitable undercut radii were identified that minimize stress and defects during demolding.

TORSIONAL BEHAVIOR OF NORMAL-STRENGTH REINFORCED CONCRETE BEAMS

open access: yesJournal of Engineering and Sustainable Development, 2015
Recent methods for torsional design of reinforced concrete beams tend to the use of space truss analogy,instead of the earlier skew bending theory. A total of (101) rectangular beams made of normal strengthconcrete (NSC) that failed under pure torsion ...

In vivo loading on the hip joint in patients with total hip replacement performing gymnastics and aerobics exercises

open access: yesScientific Reports, 2021
A further increase in the number of total hip arthroplasty (THA) is predicted, in particular the number of young THA patients has raised and with it their demands.

Resultant force, torsional moment around the implant stem and bending moment in the femoral neck.

open access: yes, 2013
View from posterior. The torsional moment Mtors rotates the implant backwards around its stem axis. The bending moment Mbend acts in the middle of the femoral neck. α = CCD angle.

Dynamic Fluorescence Modulation via Light‐Driven Competitive Protonation

open access: yesAdvanced Optical Materials, EarlyView.
A two‐component molecular system demonstrates reversible, light‐driven fluorescence write–erase cycling and thermal imaging. Illumination of a merocyanine photoacid transfers a proton to a highly efficient fluorescent pyridinium dye, switching its emission color; thermal relaxation reverses the process in the dark.

Waveguide Photoactuators: Materials, Fabrication, and Applications

open access: yesAdvanced Robotics Research, EarlyView.
Waveguide photoactuators convert guided light into mechanical motion. Their tethered‐flexible design enables minimally invasive surgery and confined‐space robotics. This review aims to guide materials selection, device design, and system integration, accelerating the transition of waveguide photoactuators from laboratory prototypes to versatile ...

Behaviour and Design of Unstiffened Wide-Flange Members Subjected to Torsional Moment through One Flange [PDF]

open access: yes, 2016
Behaviour of the unstiffened wide flanged member is not characterized by the available literature or current design standards. Torsional moment applied on the one flange unstiffened member causes the member to undergo local distortions.

Liquid Crystalline Elastomers in Soft Robotics: Assessing Promise and Limitations

open access: yesAdvanced Robotics Research, EarlyView.
Liquid crystalline elastomers (LCEs) are programmable soft materials that undergo large, anisotropic deformation in response to external stimuli. Their molecular alignment encodes directional actuation in a monolithic structure, making them long‐standing candidates for soft robotic systems.

CONSTRUCTION OF TORSIONAL VIBRATION MECHANICS MODEL OF SCRAPER CONVEYOR AND ANALYSIS OF WORKING CONDITIONS THROUGH BENDING SECTION

open access: yesJixie qiangdu, 2022
This article is a study on the physical properties of the scraper under torsion. At first, the process of the scraper conveyor passing through the curved section of the conveyor is analyzed, and then on this basis, the bending moment and the additional ...
