Adaptive Hydrogels With Spatiotemporal Stiffening Using pH‐Modulating Enzymes
Advanced Functional Materials, EarlyView.The chemomechanical coupling in an adaptive hydrogel is studied to further the development of adaptive hydrogels. This coupling is achieved by embedding a pH‐modulating enzyme in a pH‐responsive hydrogel. The enzymatic reaction can be triggered locally, which generates a pH‐decreasing wave throughout the system, increasing the crosslinking density and ...

Effects of plasma actuation and hole configuration on film cooling performance
Propulsion and Power Research, 2023 In this paper, plasma actuators are arranged asymmetrically downstream the wall to improve film cooling performance. Effects of blowing ratio, hole configuration and applied voltage on flow characteristics and film cooling effectiveness were investigated

PIV measurements of the effect of pulsed blowing jet on a NACA0012 wing model [PDF]
, 2018 Wingtip vortices are present in taking off, and landing operations and their presence in airport runways must be reduced. To that end, several strategies have been considered in the last decades, being the active control one possible technical solution ...

Speckle‐Engineered Upconversion Amplification in Nanoemulsion‐Templated Hydrogel Microdomes
Advanced Functional Materials, EarlyView.Nanoemulsion‐confined PEGDA microdomes generate speckle‐like excitation fields that strongly amplify upconversion luminescence upon dehydration, enabling filter‐free visible readout with reversible on–off switching. DMD‐based lithography yields scalable, shape‐programmable arrays for moisture‐responsive displays and optical encryption.

SİLİNDİRİK ENJEKSİYON DELİKLERİNDE FİLM SOĞUTMA İNCELEMESİ
Havacılık ve Uzay Teknolojileri Dergisi, 2006 This paper deals with experimental and numerical investigation of the film cooling effectiveness on a flat plate. Eleven injection holes on the model are in a single row. The holes have cylindrical cross section and they are 8.5 mm diameters.

Advanced Functional Materials, EarlyView.We report phosphine‐oxide interlayers for wide‐bandgap perovskite solar cells, in which tuned P = O Lewis basicity enables selective passivation of buried NiOx/perovskite interfaces and introduces interfacial dipoles that strengthen the built‐in field.

Film cooling characteristics of squealer tip of a turbine blade
Xibei Gongye Daxue XuebaoThe high-speed and high-temperature gap leakage flow in the turbine blade tip clearance directly scours the tip of the rotor blade and generates a local high-temperature region, so the active and passive control of the gap leakage flow is very important.

Effect of Calcium Addition Amount and Soft Argon Blowing on Inclusions in 316L Stainless Steel
Teshugang, 2022 316L stainless steel is prepared by the production process of 20 t EAF-AOD-LF-casting ingots, and the inclusion content in steel is reduced by LF calcium treatment and bottom argon blowing.

A film model for free convection over a vertical porous plate with blowing or suction [PDF]
, 1993 A film model is described for free convective heat transfer and friction in the presence of wall suction or injection. The analysis yields a thermal correction factor, which appears to be the classical (Ackermann) expression, and a novel friction ...
