Thermodynamic Limits to Molecular Doping in Conjugated Polymers: A Perspective on Phase Behavior and Miscibility

open access: yesAdvanced Materials, EarlyView.
Molecular doping of conjugated polymers is fundamentally constrained by thermodynamic phase behavior. This Perspective reframes doping efficiency and stability in terms of miscibility limits, binodals, and solvus boundaries, highlighting the role of effective interaction parameters and charge transfer.

Miniature Soft Robot With Magnetically Reprogrammable Surgical Functions

open access: yesAdvanced Materials, EarlyView.
Miniature soft robots have great prospects to revolutionize minimally invasive treatments. Here we present a miniature soft robot, which can be reprogrammed to perform five surgical functionalities with six‐degrees‐of‐freedom motions. This soft robot can prospectively make minimally invasive surgery considerably safer and painless, and enable ...

Dexime: A Selectively Enzyme‐Degradable Hydrogel for Protein Therapeutic Release

open access: yesAdvanced Materials, EarlyView.
A dextrin‐oxime hydrogel (dexime) is produced using ketone or aldehyde modified dextrin and tetra‐oxyamine modified poly(ethylene glycol). The rheological and mechanical properties of dexime are tunable. Dexime is injectable, cytocompatible, hydrolytically stable, and selectively degradable by α‐amylase.

OPTIMAL CONTROL OF A CONTINUOUS CASTING

IFAC Proceedings Volumes, 1983
Abstract The optimal control of a continuous casting is studied. Our purpose is to improve the quality of the steel by modifying the exchange coefficient of the secondary water. cooling system, taking into account metallurgical and technical constraints.

Continuous casting of aluminum

JOM, 1971
Horizontal, continuous casting of aluminum ingot is discussed with special attention directed to metal supply, mold package, mold lubrication, ingot cooling, and alignment of equipment. In most instances, requirements are more rigorous than with vertical, discontinuous direct chill casting.

Continuous Casting of Steel

Annual Review of Materials Science, 1981
The continuous casting process is now firmly established in the world steel industry. This paper reviews the history of its development, the characteristics of plants using it, the quality of the steel produced, and finally its future development. In conventional ingot making, steel products are made by refining, ingotmaking, soaking, slabbing or ...

The continuous–casting mould

International Metals Reviews, 1978
AbstractThis review is an attempt to draw together available information on the subject of moulds for the continuous casting of steel. Particular attention has been given to the role of the gap in the heat-extraction process and. the influence of mould design, operating variables, steel chemistry, and lubrication type on the mould heat flux.

Segregation in continuous casting

Ironmaking & Steelmaking, 2005
AbstractThis informal meeting organised by the Steel Technical Committee of the Institute of Materials, Mineral and Mining covered segregation in a wide range of carbon steels cast as slab, bloom and billet sections. The subject matter was wide-ranging and a prime intention was to generate debate. Alan Scholes, and colleagues A. W. Smith, S.

Continuous Casting (Concast)

2020
Continuous casting may be defined as teeming of liquid steel in a short mould with a false bottom through which partially solidified cast is continuously withdrawn at the same rate at which liquid metal is poured into the mould.
