Nanoscale Secondary Ion Mass Spectrometry for Quantifying Membrane Fouling: Fouling Layer Structure and Chemical Interaction

open access: yesAdvanced Science, EarlyView.
Nanoscale secondary ion mass spectrometry (Nano SIMS) is established as a powerful analytical tool to visualize and quantify the membrane fouling layers. ABSTRACT Membrane technology has garnered considerable attention for applications in wastewater treatment and resource recovery. Nevertheless, membrane fouling remains a major barrier, yet the lack of

Mineral resource management: Evaluating mineral resource throughput management

open access: yesSouth African Journal of Business Management, 2016
Mining operations are increasingly challenged to sustain and improve its profitability. Mineral Resource Throughput Management (MRTM) is showing immense promise to become a fit for use mining management and improvement methodology. Research indicated that the three dimensions of MRTM, namely physical and non-physical constraint management, product ...

Marine Metallic Mineral Resources of the Pacific Basin [PDF]

open access: yes
In the 1970s and 1980s, the ocean became a focus of attention for mineral producers and consumers. This paper surveys that trend with particular emphasis on several specific metals and types of resource deposit.

High‐Performance Recycling Biobased Photopolymers for 3D Printing

open access: yesAdvanced Science, EarlyView.
By using biobased phenols like eugenol, novel biobased photopolymers containing dissociative phenol‐carbamate bonds are designed for 3D printing. Meanwhile, a “mixed‐monomer assisted recycling” strategy is proposed to recycle the materials. The resulting materials not only achieve high‐performance and excellent chemical recyclability simultaneously ...

Multifunctional Eutectic Mixtures Enable Integrated Recovery of U, Pu, and Sr From Nuclear Waste

open access: yesAdvanced Science, EarlyView.
A novel class of multifunctional eutectic mixtures, crafted from crown ether and organophosphorus molecules, achieves highly efficient, simultaneous recovery of uranium, plutonium, and strontium from nuclear waste. The material operates via a dual “coordination‐encapsulation” mechanism within self‐assembled reverse‐micelle structures, offering a ...

Reinforcing Oxygen Activation of Spinel Oxide via Mn─O Covalency Engineering for VOCs Oxidation

open access: yesAdvanced Science, EarlyView.
A MnCo spinel catalyst with weakened Mn─O covalency was synthesized via a hard‐template method. The reduced Mn─O covalency facilitates localized electron redistribution, promoting the activation of both molecular oxygen and lattice oxygen, and thereby enabling the efficient and complete oxidation of VOCs (ethyl acetate, toluene, and propane).
