Spatially Tailorable Liquid Crystalline Elastomer Alignment During Digital Light Process 3D Printing

open access: yesAdvanced Functional Materials, EarlyView.
Here, we report the fabrication of 3D printable liquid crystalline elastomer (LCE) structures with spatially tailorable alignment domains within the same layer. This work addresses the long‐standing challenge of preparing complex 3D LCE architectures with patterned functional domains to achieve nonlinear deformations. Fabrication of multi‐domains in 3D

Characteristics of in-out intermittency in delay-coupled FitzHugh-Nagumo oscillators

open access: yes, 2018
We analyze a pair of delay-coupled FitzHugh-Nagumo oscillators exhibiting in-out intermittency as a part of the generating mechanism of extreme events.

Geometrical Designs in Volumetric Bioprinting to Study Cellular Behaviors in Engineered Constructs

open access: yesAdvanced Healthcare Materials, EarlyView.
Curvature and spatial confinement guide cell behavior in volumetrically printed 3D constructs. Endothelial cells align and spread along specific geometries, while metastatic osteosarcoma cells proliferate independently of structural cues. Label‐free holographic microscopy captures real‐time, long‐term cell–material interactions, highlighting Gel‐PEG's ...

Craftsmanship in Gaziantep: Saddle-making and Gunny sack making

open access: yesGaziantep Üniversitesi Sosyal Bilimler Dergisi, 2017
Gaziantep is one of the cities where traditional professions have been already performed. It is fact that supply-demand balance is a determinant in terms of these occupations’ future, however, academic studies on traditional professions have an essential

Néel Tensor Torque in Polycrystalline Antiferromagnets

open access: yesAdvanced Materials, EarlyView.
This work introduces a Néel tensor torque based on a rank‐two symmetric tensor capturing spin correlations in a polycrystalline antiferromagnet. It shows the Néel tensor can be shaped and reshaped through the spin‐orbit torque (SOT) technique, enabling field‐free SOT switching with a specific polarity of the adjacent ferromagnet. This discovery opens a

Comparison of rider stability in a flapless saddle versus a conventional saddle. [PDF]

open access: yesPLoS ONE, 2018
The purpose of a saddle is to improve the rider's safety, security, and comfort, while distributing the forces exerted by the rider and saddle over a large area of the horse's back without focal pressure points.

Labrador Sea freshening at 8.5 ka BP caused by Hudson Bay Ice Saddle collapse

open access: yesNature Communications, 2019
A significant reduction in the Atlantic Meridional Overturning Circulation and rapid northern Hemisphere cooling 8200 years ago have been linked to the final melting of the Laurentide Ice Sheet.

Observation of Topological Chirality Switching Induced Freezing of a Skyrmion Crystal

open access: yesAdvanced Materials, EarlyView.
Using Lorentz Transmission electron microscopy, it is shown that in the insulating van der Waals ferromagnet, CrBr3, a magnetic field can cause Bloch skyrmionic bubbles to spontaneously switch their chirality. As achiral type‐II bubbles are an intermediate state, the bubbles rapidly elongate and shrink when switching, thereby inducing a freezing of the
