Influence of Micropillar Height Modulation on Droplet Evaporation and Wetting State Transitions

Advanced Materials Interfaces, EarlyView.
Controlling droplet evaporation dynamics is crucial across many fields. Here, it demonstrates laser‐fabricated polymer micropillar arrays with tailored height variations to regulate evaporation behavior. While all arrays exhibit superhydrophobic wetting, their distinct height profiles effectively slow evaporation and alter evaporation modes ...

Richardson's pair diffusion and the stagnation point structure of turbulence [PDF]

, 2002
DNS and laboratory experiments show that the spatial distribution of straining stagnation points in homogeneous isotropic 3D turbulence has a fractal structure with dimension D_s = 2.

Investigation of Exothermic Behaviors of Energetic Particles in Microfluidics Channels

Advanced Materials Technologies, EarlyView.
Scheme and representative frames of delivery, ignition, and combustion process of core@shell Al@CuO energetic material in a microchannel. The electrical discharge occurred at the throat of microchannel leads to the combustion of the energetic reaction, causing the formation of high‐momentum butterfly‐shaped jet at the throat.

Experimental Data on Stagnation-Point Gas Injection Cooling on a Hemisphere-Cone in a Hypersonic Arc Tunnel [PDF]

Exploratory tests were made to determine the reduction of heat transfer resulting from ejection of gases at the stagnation point on a hemisphere-cone at a nominal Mach number of about 9 and at stagnation enthalpies up to 1600 BTU per pound.

Advanced Ceramics in Aerospace and Defense: The Interrelationship between Traditional and Additive Manufacturing Approaches

Advanced Materials Technologies, EarlyView.
Additive manufacturing revolutionizes production by enabling on‐demand, customized, and sustainable manufacturing with streamlined supply chains. While metal and polymer AM are well‐established, advanced ceramic AM is rapidly emerging, overcoming traditional material challenges.

Organic Neuromorphic Transistors with Crosslinked Poly(vinyl alcohol)‐Based Memory Layers Controlled by Thermal Annealing Process

Advanced Materials Technologies, EarlyView.
The crosslinked poly(vinyl alcohol) (X‐PVA) in the presence of acidic polymer catalyst (PAMPSA) is formed in solid‐state films by thermal annealing at 150 ℃ for 10 min, delivering the best hysteresis characteristics for efficient organic synaptic transistors (OSTRs) with a recognition accuracy of 96%.

Advanced Image‐Integrated Smart Windows using Printed Electrochromic Polymer‐Dispersed Liquid Crystal Droplets

Advanced Optical Materials, EarlyView.
This study presents printed image‐integrated smart windows that simultaneously control color and transmittance using electrochromic polymer‐dispersed liquid crystals (ECPDLCs). By optimizing the electrochromic LC composition and refining the drop‐on‐demand printing process, precise image integration and dynamic optical control are achieved.

Transformation of a Silicate Material for Carbon Negative Magnesia‐Based Cement via Electrochemistry

Advanced Science, EarlyView.
The transformation of a magnesium trisilicate material via water electrolysis into precursor phases necessary for magnesium‐based M‐S‐H cement is explored. The dissolution of the material mediated electrochemically is monitored, and the analysis of the resulting phases indicate their suitability as effective precursors for M‐S‐H cement.

Long time Evolution of Quantum Averages Near Stationary Points

, 2003
We construct explicit expressions for quantum averages in coherent states for a Hamiltonian of degree 4 with a hyperbolic stagnation point. These expressions are valid for all times and "collapse" (i.e., become infinite) along a discrete sequence of ...
