Removal of Natural Organic Matter Fractions by Kaolin/Fly Ash Ceramic Microfiltration Membrane in Drinking Water: Insights from a Laboratory Scale Application

open access: yesAdvanced Materials Interfaces, EarlyView.
The prepared ceramic membrane exhibited 28.84 µm average pore size and hydrophilic properties (≈27.4° contact angle). FTIR shows the presence of aluminol, siloxane, and hydroxyl groups and XRD confirms the presence of quartz and kaolinite phases. Separation of natural organic matter from drinking water is achieved by microfiltration at 0.25 bar and is ...

The mOxy-CaL Process: Integration of Membrane Separation, Partial Oxy-combustion and Calcium Looping for CO2 Capture [PDF]

open access: yes, 2018
CO2 capture and storage (CCS) is considered as a key strategy in the short to medium term to mitigate global warming. The Calcium-Looping process, based on the reversible carbonation/calcination of CaO particles, is a promising technology for post ...

Manufacture of 3D Compact Graphene Oxide Macrostructures

open access: yesAdvanced Materials Interfaces, EarlyView.
This article discusses methods to manufacture 3D graphene oxide‐based compact macrostructures, including molding, origami and kirigami, stimuli‐responsive deformation, and 3D printing. The compact morphology makes the graphene oxide‐based structures achieve high mechanical stiffness and strength to satisfy applications that need excellent mechanical ...

Structural Insights Into Aluminum‐Doped Manganese Dioxides as Promising Materials for Direct Lithium Extraction: Modeling and Mechanism Study

open access: yesAdvanced Materials Interfaces, EarlyView.
A two‐stage sorption mechanism is proposed for Al‐doped HMnO in direct lithium extraction. Batch sorption experiments and modeling identify two key sorption sites on Al‐HMnO: surface sites (planar and edge) and vacancy sites (W). At pH 12, Stage I involves surface ion exchange, followed by Stage II, where surface complexation occurs between Li⁺ ions ...

Effects of fuel oxygenation and ducted fuel injection on the performance of a mixing-controlled compression-ignition optical engine with a two-orifice fuel injector

open access: yesApplications in Energy and Combustion Science, 2021
This paper describes results from an optical-engine investigation of oxygenated fuel effects on ducted fuel injection (DFI) relative to conventional diesel combustion (CDC). Three fuels were tested: a baseline, non-oxygenated No.
