Leveraging Digital Advanced Manufacturing to Enable Polymer Electrolyte Fuel Cells With Ultrahigh Gravimetric Power Density

Advanced Energy Materials, EarlyView.
This study employs digital advanced manufacturing to develop lightweight, compact porous distributors as alternatives to conventional bipolar plates in PEM fuel cells. A graphene‐coated nickel foam achieves a power density of 1.52 W cm−2, while titanium‐based designs deliver lightweight solutions: an LPBF‐fabricated Gyroid lattice reaches 1.36 W cm−2 ...

The Christmas Island Seamount Province, Indian Ocean: Origin of Intraplate Volcanism by Shallow Recycling of Continental Lithosphere? [PDF]

, 2011
The east-west-trending Christmas Island Seamount Province (CHRISP, 1800x600 km) in the northeastern Indian Ocean is elongated orthogonal to present-day plate motion, posing the question if a mantle plume formed this volcanic belt.

Light Stability of Laser‐Assisted Glass Encapsulated Perovskite Solar Cells under Different Atmospheres

Advanced Energy Materials, EarlyView.
This study presents a laser‐assisted glass‐frit encapsulation method for perovskite solar cells, comparing air‐, nitrogen‐, and CO2‐filled cavities. Results show that excluding oxygen and moisture significantly improves stability under illumination. The findings reveal the critical role of trapped gases in degradation, providing a pathway to durable ...

Quantification of Gaseous Products Evolved at Industrially Relevant Current Densities During CO2 Electroreduction and Water Electrolysis Using Online Gas Chromatography

Advanced Energy and Sustainability Research, EarlyView.
The dilution of gaseous products obtained at high‐current densities during CO2 electroreduction or water electrolysis enables their accurate quantification via online gas chromatography, which is crucial for reliable catalyst benchmarking. The corresponding Faradaic efficiencies can then be calculated with low deviations using two different instruments,

Toward Industrial Electrosynthesis of Ethylene: Energy‐Efficient and Stable Acetylene Semi‐Hydrogenation on a Copper Phosphide/MXene Electrocatalyst

Angewandte Chemie, EarlyView.
Cu3P nanoparticles anchored on MXene via Ti─O─P bonds exhibit enhanced stability and resist agglomeration during the electrochemical semi‐hydrogenation of C2H2 to C2H4. Ti3C2/Cu3P achieves a record energy efficiency of 23.0% at 0.2 A cm−2 and stable operation in a 4 cm2 MEA for over 100 h at 1.0 A.

Drivers of Farmers' Contract Compliance Behavior: Evidence From a Case Study of Dangote Tomato Processing Plant in Northern Nigeria

Agribusiness, EarlyView.
ABSTRACT Contract farming is a viable strategy agribusinesses rely on to strengthen coordination across actors in the value chain. However, low contract compliance remains a significant setback to agribusinesses' contract performance in low‐ and middle‐income country context.

Harnessing Controlled Dealloying–Support Coupling for Ultrastable PtNi Catalysts in PEMFC Applications

Angewandte Chemie, EarlyView.
A controllable alloying–dealloying strategy constructs PtNi core–shell nanoparticles confined within an N‐doped carbon framework. Selective ammonia‐assisted dealloying forms a Pt‐rich shell while immobilizing Ni as Ni–N/C moieties, synergistically stabilizing the catalyst.

Transient modeling of extraction columns: Parameter estimation, uncertainty analysis, and operation optimization

AIChE Journal, EarlyView.
Abstract Despite extensive modeling efforts in extraction research, transient column models are rarely applied in industry due to concerns regarding parameter identifiability and model reliability. To address this, we analyzed uncertainty propagation from estimated parameters in a previously introduced column model and assessed identifiability via ill ...
