Selective ring opening (SRO) catalysts transform polycyclic molecules in low grade oil to produce cleaner burning diesel fuel. Mechanistic insight, structure-reactivity relationships, catalyst design, and future opportunities for pyrolysis oil refining from municipal solid waste are discussed.

Regenerative cooling paired with catalytic cracking of hydrocarbons can address thermal management and efficient fuel combustion in supersonic air streams, as a sustainable approach in developing high-speed flight vehicles.

Carbon capture and storage (CCS) is vital to climate change mitigation, and has application across the economy, in addition to facilitating atmospheric carbon dioxide removal resulting in emissions offsets and net negative emissions. This contribution reviews the state-of-the-art and identifies key challenges which must be overcome in order to pave the way for its large-scale deployment.

Photovoltaic-coupled electrolysis and photoelectrochemical water splitting are two options for storing solar energy as hydrogen. For each technology, the energy inputs and hydrogen output need to be considered to compare the overall energy balance.

Highly deformable crosslinked polymer particles enhance perovskite solar cell passivation and stability by binding and distributing throughout the film.

This work designed a nanostructured hybrid catalytic layer on commercial Si absorber to empower the artificial leaf for solar-driven ammonia and value-added chemicals production.

Extended high-entropy alloy electrocatalysts as a platform to investigate electrocatalytic CO oxidation and surface structure–property relations.

Polyanion modification represents an alternative low-cost strategy to improve the performance of lithium nickel oxide cathode materials.

Mobile ions cause deterioration in both device performance and stability of lead halide perovskite devices. This study provides direct evidence for substantial suppression of ionic migration effects in tin-containing perovskite compositions.

Through experiment and theory, this work explains how a set of OMIEC polymer electrodes selectively reduce oxygen to hydrogen peroxide.

With in situ X-ray powder diffraction and multi-edge X-ray absorption spectroscopy, we probe high entropy alloy nanoparticle formation. When inhibiting precursor mobility, single-phase formation is governed by stochastics and favored for five elements.

Kicking out water: optimising the interaction between support hydrophobicity and surface acid sites in WO_x/ZrO_x/PMO catalysts unlocks an efficient route for the upgrading of low-quality waste bio-oil feedstocks to biodiesel.

Using atomically flat SrIrO₃ as a model electrocatalyst for water oxidation, we study the interplay between Sr²⁺ leaching and perovskite dissolution at the nanometer scale through electrochemical atomic force microscopy.

We combine experiments with density functional theory calculations, statistical analysis, and machine-learning to reveal the structure–absorption strength relationship and predict the absorption strength of organic non-fullerene acceptors.

We present a new framework to study organic photovoltaic devices in which a model that integrates device physics with excited state dynamics is applied to explain transient and steady-state spectroscopic and optoelectronic measurements.

Band-gap-graded CZTSSe was formed successfully, and the carrier transport through the p-n junction was improved greatly; thus, the power conversion efficiency was increased by 45%.

Coulombic stabilization and large kinetic barrier in concert stabilize oxygen holes and mitigate voltage hysteresis during oxygen redox of positive electrodes in batteries.

The manufacturing costs of CZTS with different substrates, major cost drivers, and cost reduction strategies are analyzed. Potential market niches of CZTS products and techno-economic requirements for CZTS commercialization are explored.
