Filtered density functions from direct numerical simulation of a reactive jet in cross-flow
, 2010 Direct numerical simulation (DNS) with multi-step hydrogen-air chemical kinetics is used to investigate the nearfield of a flame stabilized above a reactive jet in cross-flow (JICF). JICF configurations are typically used where rapid mixing is desirable;

Numerical Simulation on Dissolved Oxygen in Ohmura Bay [PDF]
, 2005 In Ohmura Bay, several kinds of environmental problems, such as eutrophication, depletion of dissolved oxygen at sea bottom, and so on, are occurred recently. It is necessary to make clear the mechanism on water quality changes from the interdisciplinary

Advanced Engineering Materials, EarlyView.The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

Laser Powder Bed Fusion of Alumina: Effects of Scanning Strategies on External and Internal Defects
Advanced Engineering Materials, EarlyView.This study investigates how scanning strategies affect pure alumina in laser powder bed fusion. Linear 45° scanning yields uniform surfaces but high porosity, while the island‐concentric strategy provides higher density with through‐holes favorable for infiltration. Findings highlight pathways toward optimizing defect‐free alumina parts.

Advanced Engineering Materials, EarlyView.This study presents a reversible temperature sensor with high switching ratio, ∼103. The device is fabricated using PET‐ITO and carbon nanotube dispersions in alkane. Considering its application in cold chain logistics, a proof‐of‐concept with LED is showcased. Thus, a temperature drop below the threshold temperature (crystallization temperature of the

Planar Solid‐State Nanopores Toward Scalable Nanofluidic Integration Based on CMOS Technology
Advanced Engineering Materials, EarlyView.We present a scalable silicon‐based fabrication strategy for planar solid‐state nanopores to enable their integration with complex nanofluidic systems. Prototype devices demonstrate normal voltage‐current characteristics, good noise performance, and appreciable streaming currents. Our CMOS‐compatible fabrication process offers precise geometric control
