Flexible Ag2Se-based thin-film thermoelectrics for sustainable energy harvesting and cooling

Nature Communications
The high cost and complexity of fabrication limit the large-scale application of flexible inorganic thermoelectric materials. Currently, Bi2Te3-based materials are the only commercially viable option, but the inclusion of Te significantly increases ...

Boosting Photo-Fenton Activity of FeWO₄ via Mn Doping for Pollutant Degradation: Band Structure Engineering and Enhanced Reactive Oxygen Species Generation

Inorganics
Photo-Fenton technology is considered an effective method for removing organic pollutants from water. In this work, a novel Mn-doped FeWO4 (Mn-FeWO4) photocatalyst was synthesized via a one-step hydrothermal method and applied for the photo-Fenton ...

Greenwashing, carbon emission, and ESG

Business Strategy and the Environment
AbstractRecent decades have seen an increasingly awareness of climate changes, putting a pressure on companies to do more to deal with carbon emission. One of the popular measures used in assessing how well a company commits to sustainable development and reduces carbon emissions is ESG ratings.

Carbon dioxide emission scenarios for the USA [PDF]

Energy Policy, 2006
A model of carbon dioxide emissions of the USA is presented. The model consists of population, income per capita, economic structure, final and primary energy intensity per sector, primary fuel mix, and emission coefficients. The model is simple enough to be calibrated to observations since 1850. The model is used to project emissions until 2100.

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

Advanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

Structural evolution-facilitated luminescence of Sm3+ in whitlockite-type phosphors with anti-thermal quenching behavior

Journal of Advanced Ceramics
Sm3+ luminescence has pivotal significance in the field of optoelectronics. However, their poor luminescence efficiency severely hinders their practical application as Sm3+-activated optical materials.

DNA‐Templated 2D Heterostructures as Phototriggered Dynamic Nanohybrids: From Releasing Molecular Loads to Controlling Enzyme Biocatalytic Function

Advanced Functional Materials, EarlyView.
DNA strands are employed both as dynamic linkers and nanoscale templates for the integration of Ag2S nanoparticles on MoS2, which in turn imparted photothermal responsiveness; this feature permits the selective cargo (fluorophore, quantum dots or an enzyme) release from the MoS2 surface in response to local heat induced by light irradiation.

Enabling ultra-flexible inorganic thin-film-based thermoelectric devices by introducing nanoscale titanium layers

Nature Communications
Here, we design exotic interfaces within a flexible thermoelectric device, incorporating a polyimide substrate, Ti contact layer, Cu electrode, Ti barrier layer, and thermoelectric thin film. The device features 162 pairs of thin-film legs with high room-

Polarizable Vanadium Dipoles Promote Water Dissociation on Vanadium‐Based Metal Organic Framework

Advanced Functional Materials, EarlyView.
The polarization of unpaired V 3d electrons weakens the H─O bond to improve water dissociation by the dual Vδ+:O─H and Pλ−:H─O coupling hydrogen bonds formation and relaxation. P@V‐MOF electrocatalyst shows low overpotentials (94 mV in acid, 178 mV in neutral, and 77 mV in alkaline solutions) with excellent stability for effective overall water ...
