Surface hydration‐induced damage in tight oil‐bearing sandy conglomerate reservoirs

open access: yesDeep Underground Science and Engineering, EarlyView.
A series of techniques such as X‐ray diffraction, scanning electron microscopy, energy‐dispersive spectroscopy, conductivity tests, and infrared thermal imaging were used. The key findings are the identification of a two‐stage surface hydration process and the elucidation of the effects of various minerals and elements on the hydration process ...

Low‐Ru‐Content CuCoRu Aerogel for Boosted Electrocatalytic Nitrate Reduction to Ammonia

open access: yesEcoEnergy, EarlyView.
Low‐Ru‐content Cu5Co5Ru aerogel with enhanced hydrogenation ability and 3D robust aerogel skeletons enables high‐efficiency and long‐term electrocatalytic nitrate reduction to ammonia at low overpotential, achieving an exceptional ammonia yield rate of 2.7 ± 0.1 mmol cm−2 h−1 and a high Faradaic efficiency of ∼97% at −0.1 V versus RHE as well as an ...

Optimizing Intermediate Adsorption on FeNi3 Alloy by Substrate Defect‐Engineering for Enhanced Oxygen Electrocatalysis

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The presence of carbon edge defects and graphitic valley nitrogen significantly alters the energy band structure of the catalyst, enhancing the desorption of oxygen‐containing intermediates and thereby improving the performance of the oxygen reduction reaction (ORR), oxygen evolution reaction (OER), and zinc‐air battery (ZAB).

Bioinspired Crossmodal Tactile Sensory Nerve for High‐Accurate Object Recognition

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
An artificial crossmodal sensory neuron system (ACSNS) that combines a complementary memristor with high‐sensitivity pressure–temperature bimodal sensors, which integrate tactile perception, information storage, and neuromorphic computing. With the aid of machine learning, this ACSNS presents an improved accuracy of 96.67% in recognizing temperatures ...

Cardiac remodelling in the era of the recommended four pillars heart failure medical therapy

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1029-1044, April 2025.
Abstract Cardiac remodelling is a key determinant of worse cardiovascular outcome in patients with heart failure (HF) and reduced ejection fraction (HFrEF). It affects both the left ventricle (LV) structure and function as well as the left atrium (LA) and the right ventricle (RV).

The Impact of Freedom of Speech on Conspiracy Beliefs

open access: yesEuropean Journal of Social Psychology, EarlyView.
ABSTRACT Conspiracy beliefs are often portrayed as a threat to democracies. However, less is known about the extent to which the state of democracy may affect conspiracy beliefs. Hence, we investigated the impact of the societal level of freedom of speech on conspiracy beliefs. In Study 1, using aggregated nation‐level data (N = 68 countries), we found
