Spray‐Assisted Fabrication of Cellulose Photonic Pigments on Superhydrophobic Surfaces

Advanced Materials, EarlyView.
A method to directly produce structurally colored microparticles by drying cholesteric cellulose nanocrystal microdroplets on a superhydrophobic surface is reported. This approach has several key advantages that can unlock large‐scale fabrication of sustainable photonic pigments, including exploiting existing industrial techniques (e.g. aerosolization),

Charging of an Air–Rock Bed Thermal Energy Storage under Natural and Forced Convection

Energies
An air-rock bed thermal storage system was designed for small-scale powered generation and analyzed with computational fluid dynamics (CFD) using ANSYS-Fluent simulation. An experimental system was constructed to compare and validate the simulation model

Impact of background flow on dissolution trapping of carbon dioxide injected into saline aquifers [PDF]

arXiv, 2011
While there has been a large interest in studying the role of dissolution-driven free convection in the context of geological sequestration, the contribution of forced convection has been largely ignored. This manuscript considers CO$_2$ sequestration in saline aquifers with natural background flow and uses theoretical arguments to compute the critical

Engineering Magnetotactic Bacteria as Medical Microrobots

Advanced Materials, EarlyView.
Magnetotactic bacteria (MTB) are living microorganisms that produce magnetosomes for navigation using the Earth's geomagnetic field. Their built‐in magnetic components, along with their intrinsic and/or modified biological functions, make them one of the most promising platforms for making future living and programmable microrobots.

Convection regime between canopy and air in a greenhouse

Scientia Agricola, 2006
The use of covering materials in protected environments modifies the air movement close to the crop canopy compared to external environment, which changes the heat and mass transfer between canopy and air. Several researches have been made in greenhouses

Tidal flows with convection: frequency-dependence of the effective viscosity and evidence for anti-dissipation [PDF]

, 2019
Tidal interactions are important in driving spin and orbital evolution in planetary and stellar binary systems, but the fluid dynamical mechanisms responsible remain incompletely understood. One key mechanism is the interaction between tidal flows and convection.

Efficient Autonomous Dew Water Harvesting by Laser Micropatterning: Superhydrophilic and High Emissivity Robust Grooved Metallic Surfaces Enabling Filmwise Condensation and Radiative Cooling

Advanced Materials, EarlyView.
Laser micropatterning is presented as a promising technology in the search for autonomous dew water harvesting materials. Laser‐grooved metallic surfaces achieve simultaneously high infrared emissivity and superhydrophilicity, which gives them self‐cooling properties under atmospheric radiative deficit and the ability to condense water in an efficient ...
