Investigating depressant behaviour in the flotation of selected Merensky ores [PDF]

open access: yes, 2009
Includes abstract.Includes bibliographical references (p. 109-116).This study utilised laboratory batch flotation tests to characterise the flotation performance, with respect to sulfide and gangue minerals, of two Merensky ores with different mineralogy,

Herbivory‐Induced Stomatal Opening Triggers the Dispersal of an Invasive Insect Herbivore

open access: yesAdvanced Science, EarlyView.
The invasive leafminer Phthorimaea absoluta uniquely manipulates plant defenses by inducing stomatal opening in tomato. This response, mediated by the stomatal regulator IQM1, enhances the release of the repellent volatile benzaldehyde. This volatile triggers the dispersal of adult moths, facilitates colonization of new hosts, and leads to rapid ...

Optimization of induced gas flotation parameters for removal efficiency of near-water-density oils using response surface methodology [PDF]

open access: yesJournal of Particle Science and Technology
Induced gas flotation (IGF) is an efficient physical method for separating dispersed oil from produced water. This study optimized IGF parameters for oils with near-water density (specific gravity ≈ 0.9 g.cm-3) using response surface methodology (RSM ...

Atomistic Kinetics of Dislocation‐Mediated Grain Growth in Monolayer MoS2

open access: yesAdvanced Science, EarlyView.
Atomic‐resolution in‐situ heating microscopy directly visualizes dislocation‐mediated grain boundary migration and grain growth in monolayer MoS2. Mobile grain boundaries migrate through collective motion of Mo 5|7 dislocations, whereas S 5|7 defects remain largely immobile.

INVESTIGATION OF IRRIGATION INFLUENCE MADE BY FOAMED MOTHER SOLUTION ON EFFICIENCY OF SECONDARY ENRICHMENT

open access: yesНаука и техника, 2013
The secondary enrichment of a flotation concentrate in  the bubble column is considered as the easiest way to increase efficiency and quality of a mineral flotation process and reduce energy consumption for its implementation. The secondary enrichment of

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

Novel water treatment processes

open access: yesSubstantia, 2019
The effect of a natural, biodegradable surfactant obtained using a novel and efficient chemical reaction between cysteine (a thiol-based amino acid) and an octanoyl (C8) compound, was investigated for its application to the ion flotation removal of low ...

Spatiotemporal Thermal Modulation and Patterning using a Programmable 1024 Element Microheater Array

open access: yesAdvanced Science, EarlyView.
Programmable microheater arrays are essential for a variety of applications. However, large arrays have thus far not been realized. We introduce a programmable 32×$\times$32 microheater array consisting of heating elements – each smaller than 300 μm$\umu{\rm m}$.

Ultraclean coal production using froth flotation and acid leaching

open access: yesRevista Facultad de Ingeniería Universidad de Antioquia, 2013
Ultraclean coals represent an important raw material to elaborate high value products such as carbon fiber, electrodes, carbon foam and so on. In this work, ultraclean coals having less than 0.50% (w/w, db) of ash and 1.00% q(w/w) of mineral matter were
