Micro‐Corrugated Hydrogel Electrodes for High‐Performance Biofuel Cells via Capillary Force and Ligand Exchange‐Induced Metal Nanoparticle Assembly

open access: yesSmall, EarlyView.
We present a high‐performance enzymatic biofuel cell based on a micro‐corrugated hydrogel electrode engineered via capillary force and ligand exchange‐induced assembly of tetra(octylammonium) (TOA)‐stabilized Au nanoparticles (Au NPs). The resulting metallic TOA‐Au NPs hydrogel structure enables seamless electron transfer and stable enzyme ...

Emerging Triboelectric Nanogenerators for In‐Body Implantation

open access: yesSmall Methods, EarlyView.
This review explores functional implantable triboelectric nanogenerators in biomedical applications, discussing their mechanisms, electricity generation, and design approaches. To solve postimplantation challenges, four types of triboelectric nanogenerators (TENGs) are introduced: stretchable, bioadhesive, on‐demand biodegradable, and multiresponsive ...

Biocarbon Suitability Evaluation for Direct Injection in Blast Furnace Ironmaking

open access: yessteel research international, EarlyView.
This study examines densified biocarbon for direct injection in blast furnace ironmaking to reduce greenhouse gas (GHG). Enhanced burnout performance, along with favorable reactivity and carbon structure of the combustion residue, supports its suitability for blast furnace injection. Modeling results indicate that up to a 27% reduction in GHG emissions

Including Harvested Grain Biogenic CO2 to Address a Critical Flaw in Climate Accounting

open access: yesAustralian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT The international climate accounting system excludes both the biogenic CO2 sequestered in harvested crops and the biogenic CO2 emissions that occur when grain is digested or burned as biofuel. Despite being described in the literature as a critical flaw in climate accounting all parties within the United Nations Framework Convention on Climate
