On the Sensitivity of Kinetic Modelling to the Selection of Flotation Intervals in Batch Flotation
Batch flotation tests were conducted to recover copper minerals by flotation. Seven flotation intervals (cumulative flotation times) were chosen to characterize flotation kinetics in terms of maximum recoveries, R∞, and flotation rate distributions, f(k).

Atomistic Kinetics of Dislocation‐Mediated Grain Growth in Monolayer MoS2
Advanced 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.

Advanced Science, EarlyView.CDegSR, a new tool for imaging RNA at single molecule level in living cells was developed by researchers. Background noise was eliminated by protein engineering and making it degrade when not bound to its target. This allowed individual RNA molecules to be clearly imaged and tracked.

Probabilistic Computing via Gate‐Tunable Random Telegraph Noise
Advanced Science, EarlyView.Intrinsic random telegraph noise in metal–oxide–semiconductor field‐effect transistors is harnessed to create gate‐tunable probabilistic bits. By modulating carrier‐trapping dynamics, the device produces stochastic binary outputs with a continuous bias‐to‐probability transfer.

Advanced Science, EarlyView.In situ cryogenic STEM‐EELS and electron diffraction directly visualize Li depletion and structural degradation at the NCM523/Li6PS5Cl interface during charging. The results reveal a Li‐depleted amorphous interphase that impedes Li transport, while LiNbOy coating suppresses interfacial degradation and preserves the solid‐electrolyte structure ...

Ultralow‐Energy Analog Reservoir Computing via Reconfigurable 2‐Transistor Memory
Advanced Science, EarlyView.This work presents a reconfigurable reservoir‐computing platform based on an oxide InSnZnO two‐transistor cell in which a hold bias selects volatile relaxation for the reservoir or quasi‐non‐volatile multilevel storage for the readout. Multi‐level hold‐bias kernel tune relaxation currents to generate diverse time constants, enriching reservoir states ...

Mathematical interpretation of kinetics of the Zletovo mine rougher Pb - Zn flotation [PDF]
, 2001 Several equations that describe the kinetics of the flotation process can be found in literature regarding flotation concentration. One of the most appropriate, no doubt, is Agar’s equation.
