Single‐atom surface anchoring strategy via atomic layer deposition to achieve dual catalysts with remarkable electrochemical performance

EcoMat, 2023
Pt‐Ir catalysts have been widely applied in unitized regenerative fuel cells due to their great activity for the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER).

Enhancing the Anaerobic Biodegradation of Petroleum Hydrocarbons in Soils with Electrically Conductive Materials

Bioengineering, 2023
Anaerobic bioremediation is a relevant process in the management of sites contaminated by petroleum hydrocarbons. Recently, interspecies electron transfer processes mediated by conductive minerals or particles have been proposed as mechanisms through ...

Asymmetric Dual‐Electron Bridge Via Gradient Orbital Coupling for Robust Alkaline Oxygen Evolution in Low‐Iridium Water Electrolysis

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The engineered IrOx/FeEu‐NiTex composite, with ultralow Eu (0.72 at%) and Ir (0.14 at%) content, harnesses an asymmetric dual‐electron‐bridge structure (Ni 3d–O 2p–Eu 4f, Ni 3d–O 2p–Ir 5d) for gradient orbital coupling. This unique architecture delivers superior and robust alkaline oxygen evolution activity, enabling efficient low‐iridium water ...

Glacier melting and precipitation trends detected by surface area changes in Himalayan ponds [PDF]

The Cryosphere, 2016
Climatic time series for high-elevation Himalayan regions are decidedly scarce. Although glacier shrinkage is now sufficiently well described, the changes in precipitation and temperature at these elevations are less clear.

Defect‐Rich Ir Single‐Atom/NiMnOx Catalyst: From Surface Reconstruction to Practical PEM Electrolysis

Interdisciplinary Materials, EarlyView.
A novel IrSA─NiMnOx composite achieves remarkable oxygen evolution reaction performance in acidic media with an overpotential of 193 mV at 10 mA cm−2 and maintains stability for 800 h at 200 mA cm−2, which is attributed to the atomically dispersed Ir atoms and amorphous NiMnOx carriers and the lattice oxygen oxidation mechanism.

High-frequency monitoring through in-situ fluorometric sensors: A supporting tool to long-term ecological research on lakes

Frontiers in Environmental Science, 2023
Lake Maggiore is a site of the Long-Term Ecosystem Research (LTER) network, belonging to the deep subalpine Lake District in Northern Italy. Studies on the physical, chemical, and biological features of the lake have been performed continuously since the

Interventional Radiology Society of Australasia Quality Care Guidelines for Renal Tumour Ablation in Australia and New Zealand

Journal of Medical Imaging and Radiation Oncology, EarlyView.
ABSTRACT Image‐guided thermal ablation (radiofrequency, cryo‐ and microwave ablation) is a safe and effective primary treatment for small renal mass and localised renal cell carcinoma ≤ 4 cm (T1a) with long‐term cancer‐specific survival rates equivalent to surgical resection (Level A).

ESG Performance and Stock Market Outcomes: The Moderating Role of National Culture in a Global Setting

Business Ethics, the Environment &Responsibility, EarlyView.
ABSTRACT This study investigates the relationship between firms' environmental, social, and governance performance on stock market performance using a global unbalanced panel of 10,043 listed global firms from 2002 to 2024. Employing firm and year‐fixed effects with instrumental variable estimation, we find a robust positive association between ESG ...

Building a local reference library for metabarcoding survey of lake macrobenthos: oligochaetes and chironomids from Lake Maggiore

Advances in Oceanography and Limnology, 2022
This study represents a first reference database of genetic diversity of macroinvertebrates for a barcoding marker for Lake Maggiore, focusing on the two dominant groups of the littoral benthic fauna (chironomids and oligochaetes), commonly used for ...
