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),

Fast and Slow Crystallization-driven Convection in White Dwarfs [PDF]
ApJ 969 10 (2024)We investigate crystallization-driven convection in carbon-oxygen white dwarfs. We present a version of the mixing length theory (MLT) that self-consistently includes the effects of thermal diffusion and composition gradients, and provides solutions for the convective parameters based on the local heat and composition fluxes.

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.

DETERMINING THE PERFORMANCE OF A HEAT EXCHANGER USED IN THE FOOD INDUSTRY [PDF]
Romanian Journal of Petroleum & Gas TechnologyThe study of heat transfer in the food industry is as important as in any other industry. Food products are constantly subjected to heat treatments. For this reason, a sunflower food oil, which undergoes heat treatment in the manufacturing process, was ...

Multiple Equilibria in a Single-Column Model of the Tropical Atmosphere
, 2007 A single-column model run under the weak temperature gradient approximation, a parameterization of large-scale dynamics appropriate for the tropical atmosphere, is shown to have multiple stable equilibria.

Mechanical and Light Activation of Materials for Chemical Production
Advanced Materials, EarlyView.The actuation of stomata—referring to their opening and closing—is crucial for photosynthesis because it regulates gas exchange and water balance. Here, it is investigated if this life‐like property could enhance the photocatalytic properties of soft materials.

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 ...
