Resolving the Structural Duality of Graphene Grain Boundaries

open access: yesAdvanced Materials, EarlyView.
Cantilever ncAFM resolves the atomic structure of grain boundaries in graphene, revealing coexisting stable and metastable types. Both contain pentagon/heptagon defects, but metastable GBs show irregular geometries. Modeling shows metastable GBs form under compression, exhibiting vertical corrugation, while stable GBs are flat.

Large‐Area 2D Metasurface‐Based Triboelectric E‐Skin Arrays: Contact & Proximity Tactile Mapping with Broadband Acoustic Readouts

open access: yesAdvanced Materials, EarlyView.
Metasurface‐engineered NC‐TENG arrays integrate tactile pressure mapping, non‐contact gesture sensing, and acoustic signal readouts in one ultrathin module, and outperforms pristine PDMS in terms of electrical output and real‐time spatial mapping for next‐gen wearables.

Barycenter reflected equatorial Pacific sea level structure evolution and its indication of ENSO events

open access: yesOceanologia, 2015
Focused on the zonal and meridional response of sea level change to El Niño-Southern Oscillation (ENSO) events, this paper retrieves the overall average, positive anomaly and negative anomaly sea surface height (SSH) series of equatorial Pacific area ...

Humid‐Air Condensation Heat Transfer on Hierarchical Structured Superhydrophobic Graphite Composites

open access: yesAdvanced Materials Interfaces, EarlyView.
Humid‐air condensation on graphite composites shows that making a surface superhydrophobic is not sufficient to enhance heat transfer. A hierarchical CuO/lauric‐acid coating yields spherical droplets but promotes Wenzel‐type pinning and adds effective thermal resistance under operation.

Hadron melting and QCD thermodynamics [PDF]

open access: yes, 2013
We study in this paper mechanisms of hadron melting based on the spectral representation of hadronic quantum channels, and examine the hadron width dependence of the pressure.

Persistent positive anomalies in geopotential height drive enhanced wildfire activity across Europe

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences
Persistent positive anomalies in 500 hPa geopotential height (PPAs) are upper-air circulation patterns associated with surface heatwaves, drought, and consequently fuel aridity, elevated fire weather, and active wildfires. We examined the association between PPA events and surface fire weather and burned area at a pan-European level.

Optical Detection and Modeling of Lithium Deposition on Copper Current Collectors

open access: yesAdvanced Materials Interfaces, EarlyView.
ABSTRACT Understanding lithium (Li) deposition on copper (Cu) substrates is essential for improving the performance and lifetime of zero–excess lithium metal batteries. In this study, Li deposition was investigated under realistic coin–cell conditions using complementary scanning electron microscopy and laser scanning microscopy. A semi–automatic image

Ground-penetrating radar evaluation of the ancient Mycenaean monument Tholos Acharnon tomb [PDF]

open access: yes, 2016
The assessment of cultural heritage requires high-resolution and non-destructive methodologies. Ground-penetrating radar is widely applied in the inspection of historical buildings.
