Thermal‐Driven Diode Polarity Switching From Competing Helical Superconducting States in WTe2/α‐Fe2O3 Heterostructures

Advanced Materials, EarlyView.
A Nb‐proximitized Josephson junction based on a WTe2/α‐Fe2O3 heterostructure exhibits a robust superconducting diode effect with programmable polarity. The diode direction can be trained by magnetic fields and switched by temperature cycling, revealing tunable finite‐momentum pairing states and competing superconducting states in symmetry‐broken ...

Enhancing the syngas production yield from ethane and CO2 by optimizing the Pd–O–Ce interface

Nano Research
CO2-assisted oxidative dehydrogenation of ethane (CO2-ODHE) and dry reforming of ethane (DRE) have provided a promising way to simultaneously upgrade CO2 and ethane to produce value-added industrial feedstocks, such as syngas (CO and H2) or ethylene ...

Preparation of Synthesis Gas from CO₂ for Fischer–Tropsch Synthesis—Comparison of Alternative Process Configurations

C, 2020
We compare different approaches for the preparation of carbon monoxide-rich synthesis gas (syngas) for Fischer–Tropsch (FT) synthesis from carbon dioxide (CO2) using a self-consistent design and process simulation framework. Three alternative methods for

When Poor Exciton Dissociation Limits Photocurrents in Organic Solar Cells: Why Low Offset Non‐Fullerene Acceptor Blends Can't Be Efficient

Advanced Materials, EarlyView.
The energetic offset between the donor and the acceptor components in organic photoactive layers is central to the tradeoff between photovoltage and photocurrent losses. This Perspective covers the most important issues surrounding this topic in non‐fullerene acceptor blends, from the difficulty of accurately determining state energies and driving ...

The use of gasification solid products as catalysts for tar reforming

Renewable & Sustainable Energy Reviews, 2019
The presence of tars in syngas is a major technological constraint for upscaling biomass gasification to produce heat, power, and other value-added chemicals such as biofuels. At the same time, the solid remains from biomass gasification i.e.
