Actuation of Cell Layers in Three Dimensions

open access: yesAdvanced Materials, EarlyView.
ABSTRACT The alignment of fibers and cells in living tissues affect their mechanical properties and functionality. In this context, one can draw an analogy between tissues and nematic liquid crystal elastomers. We explore this analogy by growing fibroblasts on 2D‐patterned substrates and observing the contraction of cell sheets upon detachment from the

Short Communication: Collaborative Adsorption and Flotation of N-dodecyl Ethylenediamine with Short Chain Alcohol on Quartz

open access: yesInternational Journal of Electrochemical Science, 2015
The laboratory investigation about short chain alcohol effect on flotation performance of quartz using N-dodecyl ethylenediamine (ND) as collector was carried out through flotation tests, zeta-potential measurements, and Fourier transform infrared (FTIR)

The effect of mixing thiol collectors in the flotation of pure sulphide ores

open access: yes, 2012
Includes bibliographical references.Using mixtures of xanthate with either dithiophosphate (DTP) or dithiocarbamate (DTC) has been reported to increase the flotation performance of several sulphide flotation operations.

Neuromorphic Electronics for Intelligence Everywhere: Emerging Devices, Flexible Platforms, and Scalable System Architectures

open access: yesAdvanced Materials, EarlyView.
The perspective presents an integrated view of neuromorphic technologies, from device physics to real‐time applicability, while highlighting the necessity of full‐stack co‐optimization. By outlining practical hardware‐level strategies to exploit device behavior and mitigate non‐idealities, it shows pathways for building efficient, scalable, and ...

The interactive effect of depressant type and dosage with frother dosage in the flotation of a PGE ore

open access: yes, 2005
The valuable components of the platinum group element (PGE) bearing ores of the Bushveld complex in South Africa constitute between 1 % and as little as 0.1 % of the total mass. In the processing of these ores by flotation, the naturally hydrophobic talc

Synchronizing Tunable Luminescence and Shape Morphing in a Metal Nanocluster–Enabled Hydrogel Platform

open access: yesAdvanced Materials, EarlyView.
A nanocluster–gel platform is developed to synchronously integrate tunable luminescence and shape morphing under a single stimulus, with emission programmability encoded through cluster size modulation (Au10 → Au18). Solvent‐induced shape–optical transitions are visualized in a lotus‐shaped gel that dynamically folds and dims, enabling rapid (< 5 s ...

Difference between Traditional and Nanobubble Flotation of Fine Flake Graphite

open access: yesKuangchan zonghe liyong
China's large flake graphite resources are rich in reserves, but the use of fine flake graphite will become the main utilization resource in the future with the continuous exploitation of large flake graphite resources. [Objective] Conventional flotation

Modelling the influence of the froth phase on recovery in batch and continuous flotation cells

open access: yes, 2001
To determine model parameters, a large data set was required. This is due to the semi-empirical nature of the proposed froth model. In this regard, the use of data obtained from continuously operated cells was therefore not suitable for deriving model ...

COMPARATIVE ANALYSIS OF FLOTATION EFFICIENCIES BETWEEN MICROFLOTATION CELL AND BATCH FLOTATION CELL TESTS

open access: yesEskişehir Osmangazi Üniversitesi Mühendislik ve Mimarlık Fakültesi Dergisi
One of the most important methods in the beneficiation of sulfide ores is flotation. Flotation experiments on a laboratory scale are mainly carried out through batch flotation and microflotation tests.
