Applying Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) spectral indices for geological mapping and mineral identification on the Tibetan Plateau [PDF]

open access: yesInternational Archives of the Photogrammetry, Remote Sensing, and Spatial Information Science, XXXVIII (2010) 464-469, 2011
The Tibetan Plateau holds clues to understanding the dynamics and mechanisms associated with continental growth. Part of the region is characterized by zones of ophiolitic melange believed to represent the remnants of ancient oceanic crust and underlying upper mantle emplaced during oceanic closures. However, due to the remoteness of the region and the

Fossils of an endangered, endemic, giant dipterocarp species open a historical portal into Borneo's vanishing rainforests

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Asia's wet tropical forests face a severe biodiversity crisis, but few fossils record their evolutionary history. We recently discovered in situ cuticles on fossil leaves, attributed to the giant rainforest tree Dryobalanops of the iconic Dipterocarpaceae family, from the Plio‐Pleistocene of Brunei Darussalam (northern Borneo ...

Harnessing μ‐X‐Ray Fluorescence Spectroscopy as a Tool to Assess Extracellular Vesicle‐Induced Biomineralization

open access: yesAdvanced NanoBiomed Research, EarlyView.
This study presents an innovative approach to evaluate cell‐mediated biomineralization using μ‐X‐ray fluorescence spectroscopy. By generating elemental maps, the evaluation of mineral deposition by osteoblasts can be assessed in terms of both spatial distribution and degree of maturity.

Moisture sources tracking of a cold vortex rainstorm over Northeast China using FLEXPART

open access: yesAtmospheric Science Letters, Volume 23, Issue 12, December 2022., 2022
A typical Northeast Cold Vortex (NECV) rainstorm on July 25, 2016 occurred under a favorable atmospheric circulation background. Target particles that make significant contributions to this NECV rainstorm mainly came from the Indo‐China Peninsula, South China Sea, Bay of Bengal, and central China on relatively low levels. The largest water vapor uptake
