Hierarchically Biporous Wick Vapor Chamber With Micro/Nano Condenser for Exceeding 600 W/cm2 Heat Dissipation

Small, EarlyView.
An integrated vapor chamber couples a hierarchically biporous copper wick with a micro/nano‐textured superhydrophobic condenser to form a self‐sustained liquid–vapor loop. The device dissipates extreme heat fluxes above 600 W/cm2, even when the condenser is above the heater, by overcoming the permeability‐capillarity trade‐off in conventional vapor ...

Reactivity of Oxidized Porous Silicon with Calcium Ion in Aqueous Media: Stability, pH Behavior, and Host‐Guest Strategies

Small, EarlyView.
Oxidized porous silicon, composed of an elemental silicon porous skeleton coated with a silica shell, reacts with aqueous Ca2+ to generate a mixed silica–calcium silicate matrix that is remarkably efficient at trapping small molecules. With an emphasis on the engineering of controlled‐release drug delivery systems, this study identifies the factors ...

Recycling End‐of‐Life Solid Oxide Cell Interconnect Assemblies into Commercial‐Grade AISI 304 Stainless Steels

steel research international, EarlyView.
This study validates a recycling pathway for converting interconnect assemblies from end‐of‐life SOC stacks into commercial‐grade AISI 304 steels. Using scrap‐based steelmaking operations, austenitic cast steels with <4.0% δ‐ferrite are successfully produced.

Effect of Intrinsic Carbon in Hot Briquetted Iron on Melting and Refining Efficiency under Electric Arc Furnace Conditions for Sustainable Steelmaking with Active Use of H2‐Reduced Iron

steel research international, EarlyView.
The melting behavior of hot briquetted iron (HBI) is observed and compared with FactSage computing simulation. When using HBI in an electric arc furnace process, a proper design of intrinsic carbon content in HBI, charging ratio of HBI, and addition of lime are proposed to be essential to control the slag volume, maintain slag basicity, and mitigate ...

Double Slag Operating Standard for Mitigation of CO2 Emissions in Basic Oxygen Steelmaking

steel research international, EarlyView.
Basic oxygen furnace (BOF) steelmaking uses a double slag process (DSP) to produce low‐phosphorus steel. To reduce carbon emissions in a BOF, the hot metal ratio (HMR) must be lowered. The present article describes the optimal conditions for DSP operations under low‐HMR conditions: temperature of 1360 ± 5 °C, total Fe content of 10 ± 2 wt%, basicity (=
