Artificial Symbiosis for Bulk Production of Bacterial Cellulose Composites

Advanced Materials, EarlyView.
Co‐cultivation of the cellulose‐producing bacterium with the microalga enables bulk formation of bacterial cellulose under static incubation, with photosynthetically active oxygen‐generating sites throughout the medium. This symbiotic platform supports 3D cellulosic constructs with geometries dictated by the vessel shape.

Optical Generation of Vortices in trapped Bose-Einstein Condensates [PDF]

, 1999
We demonstrate numerically the efficient generation of vortices in Bose-Einstein condensates (BEC) by using a ``phase imprinting'' method. The method consist of passing a far off resonant laser pulse through an absorption plate with azimuthally dependent

Electron Channeling Contrast Imaging of Ferroelastic Domains

Advanced Materials, EarlyView.
A simple scanning electron microscopy technique, electron channeling contrast imaging, unveils nanoscale ferroelastic domains and their coupling to functional properties in oxide heterostructures. The work demonstrates high‐resolution mapping of both surface and buried domains, broadening the experimental toolbox for ferroic and quantum oxide systems ...

Plant chemistry and aphid parasitoids (Hymenoptera: Braconidae): Imprinting and memory

European Journal of Entomology, 2008
Emerging parasitoids of aphids encounter secondary plant chemistry from cues left by the mother parasitoid at oviposition and from the plant-feeding of the host aphid.

UniquID: A Quest to Reconcile Identity Access Management and the Internet of Things

, 2019
The Internet of Things (IoT) has caused a revolutionary paradigm shift in computer networking. After decades of human-centered routines, where devices were merely tools that enabled human beings to authenticate themselves and perform activities, we are ...

Topology and Material Optimization in Ultra‐Soft Magneto‐Active Structures: Making Advantage of Residual Anisotropies

Advanced Materials, EarlyView.
Residual magnetization induces pronounced mechanical anisotropy in ultra‐soft magnetorheological elastomers, shaping deformation and actuation even without external magnetic fields. This study introduces a computational‐experimental framework integrating magneto‐mechanical coupling into topology optimization for designing soft magnetic actuators with ...

Integrated 3D Hydrogel Waveguide Out-Coupler by Step-and-Repeat Thermal Nanoimprint Lithography: A Promising Sensor Device for Water and pH [PDF]

, 2018
Hydrogel materials offer many advantages for chemical and biological sensoring due to their response to a small change in their environment with a related change in volume.

Engineering Chiroptical Interactions through Integrating Plasmonic Arrays with Cholesteric Nanocellulose

Advanced Materials, EarlyView.
In this study, we demonstrate how the combination of plant‐based cellulose and gold nanoparticle lines produces robust, tunable chiral light control in composite films. The resulting plasmonic cellulose composite exhibits a strong plasmonic CD at the surface lattice resonance, along with an inversion of chiroptical response upon reversing the ...

Novel polymorphisms within the Dlk1-Dio3 imprinted locus in rat: a putative genetic basis for strain-specific allelic gene expression

Frontiers in Genetics, 2012
The imprinted iodothyronine deiodinase-III (Dio3) thyroid hormone metabolizing gene exhibits paternal expression in most fetal tissues, yet exhibits aberrant, maternal expression in the hippocampus in F1 offspring of Sprague Dawley (SD) x Brown Norway ...
