Influence of Flow Field Perturbations on the Rising Dynamics of Bubble–Oil Aggregates for Enhanced Oily Wastewater Treatment

Clean Technologies
Air flotation is widely used in wastewater treatment for the removal of emulsified oils and suspended solids. The complex flow disturbances generated during the flotation process play a critical role in determining separation efficiency.

Shear‐Mode Direct Piezoelectric Response of Ferroelectric Nematic Liquid Crystals

Advanced Science, EarlyView.
Periodic shear‐induced electric current measurements are reported on two archetypic ferroelectric nematic liquid crystal compounds. From the temperature, frequency and shear angle dependent results of the first and second harmonic current signals together with temperature and oscillatory rheology measurements, the effective piezoelectric coupling ...

Concentration of Silver from Recycling of Fine Powder of Wasted Videogame Printed Circuit Boards through Reverse Froth Flotation and Magnetic Separation Processes

Recycling
Electronic waste stream grows day by day; printed circuit boards are a kind of solid waste that accounts for 6% of electronic waste. When these are discarded, they can cause soil, water, and air contamination; however, if recycled, these can be ...

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 ...

SCTR–Expressing Astrocyte–Serotonergic Neuron Signaling Drives Sexual Dimorphism in Depression Through KAT7/H4ac–Foxc2 Epigenetic Axis in an AMPK‐Dependent Manner

Advanced Science, EarlyView.
Astrocytic SCTR modulates depressive‐related phenotypes via AMPKα1, whereas lowered Mt1 blunts Megalin‐dependent AMPKα2 signaling in serotonergic neurons. Diminished AMPKα2 hinders KAT7 nuclear translocation, curtails KAT7 occupancy and H4K8ac at the Foxc2 promoter, and represses Foxc2 transcription, revealing cell‐type‐specific AMPK‐linked epigenetic ...

Scale-up of column flotation

, 2007
The parameters controlling column flotation have been investigated using laboratory and pilot-scale flotation cells. It was determined that column recovery is a function of flotation rate constant, axial dispersion, retention time and fractional air hold-

Optimizing Cancer Vaccinations Using a Physiologically‐Based Pharmacokinetic/Pharmacodynamic (PBPK/PD) Model

Advanced Science, EarlyView.
Where and when should a cancer vaccine be administered? A whole‐body PBPK model demonstrates that systemic immune transport critically determines vaccination efficacy. By simulating how organ‐specific immune interactions influence treatment response, the study provides a quantitative framework for optimizing cancer vaccination strategies.

Nonlinear Ion‐Specific Control of Underwater Adhesion by Bottlebrush Polymer Interfaces

Advanced Science, EarlyView.
The efficiency of underwater adhesion is modulated by ion‐specific effects. Strongly hydrated Na+ remains separated from the mica surface by its hydration shell, preserving access to binding sites, whereas weakly hydrated K+ can partially dehydrate and occupy ditrigonal cavities.
