The reduction of magnetite and lean magnetite sinters. [PDF]

The problems encountered in at tempt.ing to determine the rate controlling step in the reduction of magnetite end sinters to iron are revealed by a survey of the pertinent literature. On the basis of previous work supplemented by the investigations reported in this thesis the probable sequence of rate controlling steps has been determined.

Determining the effective use of magnetite in lipid-magnetite suspensions

Eastern-European Journal of Enterprise Technologies, 2014
Доведено ефективність використання магнетиту в ліпідо-магнетитових суспензіях в якості дисперсійної фази, що забезпечує необхідні властивості: стійкість у часі, дисперсність та концентрацію. В якості дисперсійного середовища застосовувалися рослинні масла: кукурудзяне, соєве та соняшни-кове; в якості поверхнево-активної речовини (ПАР ...

The Hidden Harvest: Harnessing Colorado's Geodiversity and Environmental Heterogeneity for Sustainable Agritourism

Sustainable Development, EarlyView.
ABSTRACT Colorado's geologic, pedologic, topographic, hydrological, and climatic contrasts create strong but under‐synthesized opportunities for sustainable agritourism. This review investigates how geodiversity, and the broader environmental heterogeneity within which it operates, can be used to diversify farm income, strengthen place‐based visitor ...

A Platform for the Actuation of Magnetically Labeled Skeletal Muscle Cells Using Dynamic Magnetic Stimulation

Small, EarlyView.
A magnetic stimulation platform for the remote stimulation of cells is presented, consisting of a magnetic stimulator and magnetic microspheres. Skeletal muscle cells are labeled with magnetic microspheres, which act as local magnetic actuators on the cells upon application of the magnetic field.

Martian‑Regolith Simulant Confined Nanogenerators for Wireless Tactile Sensing for Human‐Machine Interface

Small, EarlyView.
A Martian regolith‐simulant/PDMS triboelectric nanogenerator is developed as an ISRU‐inspired, self‐powered tactile sensor for wireless human–machine interface applications. ABSTRACT Achieving a sustainable energy system for space missions remains challenging due to the continued reliance on Earth‐supplied materials.

Vine Tendril‐Inspired Cold‐Programmable Shape‐Memory Polymer Composites Using Sugar Beet Pulp

Small, EarlyView.
Vine tendrils inspire a bio‐derived, cold‐programmable shape‐memory polymer composite (SMPC). Magnetically guided sugar beet pulp creates mesoscale heterogeneity within a glassy matrix, producing built‐in mechanical asymmetry for rapid, solvent‐free programming by simple stretching.

Recycling‐Induced Copper Contamination of a 42CrMo4 Quench and Tempering Steel—Scaling and Susceptibility to Hot Shortness

steel research international, EarlyView.
In this study, the susceptibility to copper‐induced hot shortness of the alloy 42CrMo4 is investigated by different hot tensile tests, as well as by a detailed analysis of the formed oxidation products. While an enrichment of metallic copper and a penetration of the grain boundaries are observed, no critical reduction of the tensile test properties can

Influence of Hydrogen Fuel Mixtures on the Oxide Scale Formation of Low‐Carbon Steels in Reheating Furnace Conditions

steel research international, EarlyView.
This work illustrates how substituting natural gas with hydrogen as fuel in the reheating furnace will influence the oxide scale formation on the steel surface. Thermogravimetric analysis and characterization techniques are used to investigate oxidation behavior and the formation of oxide phases.

Using Thermodynamics and Microstructure to Mitigate Overfitting in Pellet Reduction Models

steel research international, EarlyView.
A in time and space discretized, thermodynamically sound model for direct reduction of iron oxide pellets is described. The number of fitting parameters is drastically reduced compared to existing models. Nevertheless, fitting kinetic parameters based on conversion degree data alone leads to overfitting, which can be mitigated by correlating the ...
