Shaping Liquid Crystal Rubbers by Chemical Potential Gradient

open access: yesMacromolecular Rapid Communications, EarlyView.
Depositing a low molecular weight liquid crystal drop onto a uniformly aligned LCE leads to non‐uniform swelling, enabling temporary shape changes and bending actuation. These deformations are quantitatively modeled for different alignment conditions, and methods to permanently lock desired shapes are explored.

Predicting Mesoscopic Larmor Frequency Shifts in Ex Vivo Porcine Optic Nerve

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Larmor frequency shifts in white matter (WM) vary with fiber orientation due to anisotropic microstructure. Since clinical voxels are significantly larger than these microscopic frequency variations, the measured signal represents a bulk average of local shifts.

Cultivating Sustainability: How Modern Food Practices Shape Pro‐Environmental Motivation Through Food–Nature Associations

open access: yesSustainable Development, EarlyView.
ABSTRACT Food practices have evolved alongside industrialization and urbanization. Compared to earlier generations, modern individuals grow and cook food less often and consume more processed products, weakening awareness of food's natural origins. Three studies examined explanatory pathways linking food practices to pro‐environmentalism through the ...

Programmable 3D Microfluidics Reveals Motility‐Driven Antibiotic Resistance Evolution in Gradients

open access: yesSmall, EarlyView.
Using a programmable microfluidic platform, this study shows that bacterial motility is crucial for resistance development in heterogeneous antibiotic landscapes. Motile Escherichia coli randomly migrates along antibiotic gradients, and sufficient movement is required for resistance to emerge.
