Pt‐Mediated Co‐Adsorption of Hydroxyl and Nitrogen‐Heterocyclic Species Over Cu/CuO Heterostructure Enhances Coupled Azotriazole Electrosynthesis and Dual‐Electrode Hydrogen Production

open access: yesAngewandte Chemie, EarlyView.
Pt@Cu/CuO heterostructures were designed for electrochemical N─N coupling of 3,5‐diamino‐1H‐1,2,4‐triazole. Mechanism investigation revealed that the Pt sites mediated co‐adsorption of substrates and hydroxyl on Cu/CuO sites. The elaborate Pt@Cu/CuO achieved an ultralow working potential of 0.832 VRHE with a high FE of 95%. A long‐term stability of 600

Molecular and Cellular Hallmarks of Age‐Related Vestibular Hair Cell Degeneration

open access: yesAdvanced Science, EarlyView.
This study utilizes single‐cell RNA‐seq transcriptomes, advanced imaging, and electrophysiology to examine universal and cell‐type‐specific aging signatures of vestibular hair cells. The study shows that impaired hair bundle function is a key driver of age‐related vestibular dysfunction.

EphB1‐Mediated Transient Blood‐Brain Barrier Opening Facilitates a Ferritin‐Based Nanotherapeutic for Alzheimer's Disease

open access: yesAdvanced Science, EarlyView.
We constructed a brain‐targeted AFn‐DPZ nanodrug delivery system and identified EphB1 as its receptor on the blood‐brain barrier (BBB). This system facilitates drug transport across the BBB and thereby ameliorates cognitive impairment in Alzheimer's disease.

Genesis and karst characteristics of marble agglomerate in volcanic rocks on the eastern slope of Wutong Mountain, Shenzhen

open access: yesCarsologica Sinica
Karst phenomena, such as fissures and caves, occur in the marble agglomerate of pyroclastic rocks on the eastern slope of Shenzhen’s Wutong Mountain. These features have affected the engineering projects such as subway construction and pile foundation ...

Fracture mechanics of volcanic eruptions [PDF]

open access: yes, 2009
Seismology is a key tool in the forecasting of volcanic eruptions. The onset of an eruption is often preceded and accompanied by an increase in local seismic activity, driven by fracturing within the edifice.

CALB2 is a Mechanoresistance Gene in Metastatic Prostate Cancer

open access: yesAdvanced Science, EarlyView.
Prostate cancer cell lines of differing origins were cultured over many passages while being subjected to semi‐lethal levels of fluid shear stress, representing the harsh mechanical environment these cells are subjected to in the circulation during the process of distant metastasis.

Discrimination of hot versus cold avalanche deposits: Implications for hazard assessment at Mount Meager, B.C. [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2003
The surficial deposits surrounding the Mount Meager volcanic complex include numerous avalanche deposits. These deposits share many attributes: (a) they are nearly monolithologic and comprise mainly intermediate volcanic rock clasts, (b) they lack ...

Fine description and geologic modeling for volcanic gas reservoirs

open access: yesPetroleum Exploration and Development, 2010
To understand the geology of volcanic gas reservoir development, research was carried out on volcanic rock, body lithology, lithofacies, fractures, gas and water zones, reservoir classification, and geologic modeling for volcanic gas reservoirs.

Volcanology of the Raventhorpe and Pokeno West Volcanic Complexes, South Auckland Volcanic Field [PDF]

open access: yes, 2012
The South Auckland volcanic field hosts at least 82 volcanic centres throughout the Pukekohe, Bombay, Tuakau, Pukekawa and Onewhero regions. The monogenetic basaltic volcanic field was active between 1.59 to 0.51 Ma, producing tuff rings, maar craters ...
