Blending With Insulating Polymers Enables Stable Anti‐Ambipolar Characteristics in n‐Type Organic Mixed‐Conductors for Heterogeneous Spiking Neurons

open access: yesAdvanced Materials, EarlyView.
A polymer blend of n‐type OMIEC P(gNDI‐gT2) with insulating PMMA yields mechanically stabilized, anti‐ambipolar organic electrochemical transistors (OECTs) with tunable ionic‐electronic transport. This blending allows low‐power, fast‐spiking heterogeneous Hodgkin–Huxley neurons, enabling biomimetic frequency deconvolution and reservoir computing, which

Castable Ceramic Veneers

Journal of Esthetic and Restorative Dentistry, 1989
The use of laboratory fabricated veneers for restoration of discolored or malformed anterior teeth is becoming a widely used dental technique. Etched castable ceramic veneers are an alternative to etched procelain veneers for the esthetic treatment of anterior teeth.

A melt castable energetic cocrystal

Chemical Communications, 2017
Cocrystallization leads to melt-state stabilization of the thermally unstable energetic 4-amino-3,5-dinitropyrazole, allowing for production of a melt castable cocrystalline explosive.

Castability of crown and bridge alloys

The Journal of Prosthetic Dentistry, 1985
A special saucer-shaped wax pattern was designed to evaluate the castability of five casting machines and four casting alloys. The casting machines used included one broken arm unit, one induction unit, one resistance unit, and two vacuum air pressure units.

A castability expert system

Computers & Industrial Engineering, 1993
Abstract The castability analysis of a part, its cost estimation and preparation of competitive quotations typically requires years of experience, is time consuming and is dependent on the expert personnel available. Considerable amount of personnel time is also involved in preparing these quotations.

Castability of aluminium alloys

Transactions of the Indian Institute of Metals, 2009
Castability is the ability of an alloy to be cast without formation of defects such as cracks, segregations, pores or misruns. Alloy dependent phenomena that determine castability are fluidity, macrosegregation, hot tearing and porosity. These phenomena have been known for a long time but have only recently become well understood and work is underway ...
