Infrared Photovoltaic–Battery Hybrid Systems Enabled by Colloidal Quantum Dots

open access: yesChemistry – An Asian Journal, EarlyView.
Photovoltaic–battery (PV/B) hybrid systems are key for sustainable energy but face cost and efficiency limits. Colloidal quantum dots (CQDs) enable low‐cost near‐infrared light harvesting, surpassing silicon and III–V PVs. This review analyzes CQD properties, their roles in NIR PVs and batteries, and synthesizes current research to highlight progress ...

Guide to the geology of Bradgate Park and Swithland Wood, Charnwood Forest [PDF]

open access: yes, 2010
Charnwood Forest is one of the few parts of England where there are exposures of ‘basement’ rocks dating back to Precambrian time. Its locally rugged topography is caused by these highly resistant rocks protruding as craggy knolls through a surrounding ...

“Dead Lithium” Formation and Mitigation Strategies in Anode‐Free Li‐Metal Batteries

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
Anode‐free lithium metal batteries, though promising due to their high energy density, face challenges from dead lithium formation. “Dead lithium”, disconnected from the anode, causes capacity loss, increased resistance, and safety risks. This review explores the origins of dead lithium, its impact on battery performance, and potential strategies for ...

Mobilizing mine lands for biobased decarbonization strategies

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Over 163 000 ha of mine lands in Pennsylvania (PA) have the potential to produce willow as a feedstock for renewable energy generation. Each year these lands could produce between 454 000 and 907 000 dry Mg of willow, which can be a feedstock for bioenergy (i.e., biopower) with carbon capture and sequestration (BECCS) or sustainable aviation ...

Does Formalization Facilitate Environmental Improvements in the Artisanal and Small‐Scale Mining Sector?

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This paper explores the link between formalization and environmental performance in the artisanal and small‐scale mining (ASM) sector, focusing on the case of sub‐Saharan Africa. The impression often conveyed by experts is that a commitment to formalizing ASM—that is, moves made to bring the sector's operations into the legal domain, where ...

Molten‐Salt‐Mediated Chemical Looping Oxidative Dehydrogenation of Ethane with In‐Situ Carbon Capture and Utilization

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
A sustainable alternative to steam cracking, the molten‐salt‐mediated oxidative dehydrogenation (MM‐ODH) of ethane (C2H6) in Li2CO3‐Na2CO3‐K2CO3 (LNK) couples thermal cracking with melt‐mediated CO2 capture to realize commercially competitive C2H4 and CO yields. LNK composition strongly influences MM‐ODH process outcomes.
