Marine Macroalgae as a Safe Healthy Food While Meeting Food Security Challenges Arising From Climate Changes

Food Safety and Health, EarlyView.
Planned harvesting and processing of marine macroalgae could meet future global food needs and mitigate fuel‐originated carbon dioxide responsible for climate change. Microalgal foods are nutritious and safe. The utilization of macroalgae would avoid environmental problems arising from the release of overgrowing macroalgae caused by heatwaves, which ...

A Green Amphoteric Surfactant Derived From Rapeseed Oil for Enhanced Oil Recovery From Carbonate Acidic Oil Reservoirs

Journal of Surfactants and Detergents, EarlyView.
The Green Amphoteric Surfactant Derived From Rapeseed Oil for Enhanced Oil Recovery From Carbonate Acidic Oil Reservoirs. ABSTRACT Surfactants with both positive and negative functional groups (amphoteric or zwitterionic) are particularly advantageous in acidic oil reservoirs because they remain stable under harsh chemical conditions, tolerate acidic ...

Oil-Coated Bubble Flotation for Separating Hydrophilic Particles from Water

Recycling
Froth flotation is a widely used method for the selective separation of particulates from aqueous dispersions or slurries. This technology is based on the attachment of sufficiently hydrophobic particles to the air–water interface of gas bubbles. However,

Improved GSO Optimized ESN Soft-Sensor Model of Flotation Process Based on Multisource Heterogeneous Information Fusion

The Scientific World Journal, 2014
For predicting the key technology indicators (concentrate grade and tailings recovery rate) of flotation process, an echo state network (ESN) based fusion soft-sensor model optimized by the improved glowworm swarm optimization (GSO) algorithm is proposed.

Enhanced Transmit Efficiency of a Loop Array Combined With Out‐of‐Phase Passive Dipoles for Thoracic Spinal Cord MRI at 7T

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose The design of radiofrequency (RF) coils tailored for the target anatomy is necessary to overcome the transmit field homogeneity and penetration issues at Ultra‐High‐Field (UHF). For the spinal cord, the optimal design has not yet been determined. This work intends to demonstrate the added value of a pair of passive dipoles placed under
