Thermal Structure of Turbulent Stagnating Opposed Jets with Different Temperature.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1997 Fluctuating temperature has been measured using a laser Rayleigh scattering technique along a centerline of turbulent stagnating opposed jets (cold jet velocity: 2 m/s) with different temperatures up to about 400 °C. The temperature signals show that the temperature fluctuation is characterized by spike type fluctuations with a sharp increase or ...

A Scalable Double‐Sided Wet Etching Strategy for Large‐Area Mushroom‐Shaped Bionic Adhesives
Advanced Science, EarlyView.This work presents a scalable manufacturing strategy for high‐performance, large‐area, mushroom‐shaped bio‐inspired adhesives. Using a double‐sided wet etching process, the complex 3D metal molds are fabricated rapidly and controllably. The resulting adhesive structures exhibit strong, stable adhesion under various conditions, including atmosphere and ...

Steindlian Models of Growth and Stagnation [PDF]
This paper examines Steindl’s original 1952 model and relates it to subsequent stagnationist models. The model is then extended by introducing endogenous changes in the markup and a reformulation of the investment function.

Advanced Intelligent Discovery, EarlyView.A machine learning‐guided self‐driving laboratory screened over 500 nickel‐based layered double‐hydroxide catalysts for alkaline oxygen evolution. Out of the eight metals, the robot uncovered a quaternary Ni–Fe–Cr–Co catalysts requiring only 231 mV overpotential to reach 20 mA cm−2.
