Beyond the Gold Standard: Towards Industrially Viable Electrodes for Durable Perovskite Solar Cells

Advanced Energy Materials, EarlyView.
Transparent and opaque electrode materials are mapped by raw material cost per 1 m2 electrode area and retained median device efficiency after heat–light ageing. FTO offers a lower‐cost and more stable alternative to ITO, while Cr/Al provides the lowest‐cost rear electrode investigated with Au‐like stability and substantially improved durability ...

Flow and Scour Analysis Around Monopole of Fixed Offshore Platform Using Method that Couples Computational Fluid Dynamics and Discrete Element Method [PDF]

한국해양공학회지, 2019
When an offshore foundation is exposed to waves and currents, local scour could develop around a pile and even lead to structural failure. Therefore, understanding and predicting the scour due to sediment transport around foundations are important in the

Separation and Valorization of Chlorine From Tail Gas Streams

Angewandte Chemie International Edition, EarlyView.
A commercially available ion exchange resin was found to adsorb chlorine gas selectively in the presence of other gases reversibly forming the corresponding trichloride species [IEx][Cl3]. This discovery was telescoped to an efficient process for the recycling and valorization of chlorine from industrially abundant tail gas streams to base chemicals ...

Prediction of Seabed Scour Induced by Full-Scale Darrieus-Type Tidal Current Turbine

Journal of Marine Science and Engineering, 2019
Scour induced by a Darrieus-type tidal current turbine was investigated by using a joint numerical and experimental method with emphasis on the scour process of a full-scale turbine.

Scanning Parametric Sediment Echosounder as Tool for Underwater Archaeological Prospection

Archaeological Prospection, EarlyView.
ABSTRACT Underwater cultural heritage 3D prospection techniques, especially for remains that are partly buried in the ground, are only very rarely available and often can only be applied with considerable technical effort. To overcome this limitation, we evaluate a methodological adaption of widely used and available single channel parametric sediment ...

Effect of debris accumulation on scour evolution at bridge pier in bank proximity

Journal of Hydrology and Hydromechanics, 2021
Large debris transported by flood affects scour features at bridge piers and increases the risks of structural failure. Geometric characteristics of the debris and the relative position of the pier with respect to the river bank are important parameters ...

Three-Dimensional Simulations of Scour around Pipelines of Finite Lengths

Journal of Marine Science and Engineering, 2022
In the past few decades, there have been many numerical studies on the scour around offshore pipelines, most of which concern two-dimensional setups, with the pipeline infinitely long and the flow perpendicular to the pipeline.

Purification of Advanced Therapeutics by Flow‐Through Pseudo‐Affinity Chromatography: Bi‐Specific mABs, Fc Fusion Proteins, and Adeno‐Associated Viruses

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Modern biopharmaceutical manufacturing requires purification platforms capable of processing structurally and functionally diverse products while addressing the challenge of removing persistent and high‐risk host cell proteins (HCPs).

Scour due to turbulent wall jets downstream of low-/high-head hydraulic structures

Cogent Engineering, 2016
To overcome over-prediction of the scour depths by existing methods, a mathematical model is developed based on a work transfer theory. This model predicts the equilibrium scour hole’s depth and length due to two-dimensional turbulent wall jets ...

Iron(III)‐loaded cation exchange resin: A dual approach for aqueous H2S removal and biogas desulphurization

The Canadian Journal of Chemical Engineering, EarlyView.
Left: Desulphurization method application. Right: Novel desulphurization method. Abstract The presence of hydrogen sulphide (H2S) in biogas poses significant environmental and operational challenges due to its corrosive and toxic properties. Thus, this study aimed to develop a dual‐function desulphurization system using a cation exchange resin (CIER ...
