Advanced Functional Materials, EarlyView.A new class of photoresponsive liquid‐crystalline (LC) adhesives based on biomineral‐inspired organic/inorganic colloidal hybrids is reported. These colloidal LC materials are formed by hybridization of a hydroxyapatite nanorod with azobenzene‐based forklike molecules.

Motion of Small Bubbles near a Grid Spacer in a Two by Three Rod Bundle
Journal of Fluid Science and Technology, 2008 Motion of small bubbles upstream of a grid spacer in a two by three rod bundle is experimentally investigated. Trajectories of single bubbles upstream of the grid spacer are recorded by using a high-speed video camera. An image processing method based on

Coordinated Architectural and Chemical Reinforcement in the Crushing Mandible of a Soldier Termite
Advanced Functional Materials, EarlyView.The crushing mandible of a soldier termite withstands substantial biting loads despite lacking mineral. Its cuticle is partitioned: convex teeth pair hardness and zinc enrichment with aligned chitin fibers for contact durability, while stiffer concave regions between teeth carry bending loads.

Advanced Functional Materials, EarlyView.This work reveals the UV‐curing‐induced monomer‐rich domain, oligomer‐rich domain, and entangled oligomer domain. The cured submicron films in stressed state induce interlayer nano‐wrinkle structures during the deposition of the second layer. Stress‐free cured films in relaxed state form non‐diffusive, diffusive and semi‐diffusive interlayer ...

CFD Modeling of Boiling Flow in PSBT 5×5 Bundle
Science and Technology of Nuclear Installations, 2012 Three-dimensional computational fluid dynamics (CFD) method was used to model the boiling two-phase flow in one of the PSBT 5-by-5 rod bundle tests. The rod bundle with all the spacers was modeled explicitly using unstructured computational grids.

Subchannel modeling of single rod bowing in a bundle geometry
, 2018 During operation of a nuclear power plant, nuclear fuel assemblies in a reactor core are in strong temperature and radiation fields. With fuel burnup and the presence of thermo-mechanical stresses, gaps between fuel assemblies start to increase, leading ...
