Light‐Harvesting Photothermal Hotspots Enabled by NIR Scattering‐Absorption Coupling

open access: yesAdvanced Science, EarlyView.
By coupling the broadband scattering of nanodiamonds with the plasmonic absorption of gold nanostars, this work proposes a novel strategy for the active modulation of photon transport. This strategy creates localized photothermal hotspots in turbid media and achieves a supra‐additive heating efficiency, thereby providing a universal platform for low ...

Diamond Metasurface‐Based Optical Tweezers With Enhanced Robustness

open access: yesAdvanced Science, EarlyView.
Conventional metasurface optical tweezers are hindered by thermal instability from laser heating. This work overcomes this by using diamond metasurfaces, exploiting their low thermo‐optic coefficient and minimal thermal expansion. The platform demonstrates stable particle trapping, translocation, and rotation, enabling robust miniaturized systems for ...

Graphene‐Skinned Alumina Fiber: Continuously Scalable Fabrication and Its Electrothermal Application in Fiber‐Reinforced Polymer Composites

open access: yesAdvanced Science, EarlyView.
Graphene‐skinned alumina fiber (GAF) is a new composite with graphene conformally grown on individual alumina fibers via chemical vapor deposition (CVD). GAF's dynamic, continuous and scalable production is achieved by using a home‐made roll‐to‐roll (RTR) CVD system featuring integrated degumming and growth chambers. GAF possesses tunable conductivity,

Aggregation‐Induced Resonance Energy Transfer in Polymer Dots to Boost Electrochemiluminescence Performance for Bioimaging of Glycan on Cells

open access: yesAdvanced Science, EarlyView.
This study pioneers an aggregation‐induced resonance energy transfer mechanism by synergistically integrating aggregation‐induced emission (AIE), resonance energy transfer (RET), and thermally activated delayed fluorescence (TADF) within co‐reactant conjugated polymers to develop self‐enhanced ECL emitters, which achieves an ECL efficiency up to 92.6 ...

Camera trapping for conservation

2021
Abstract Camera traps use a motion sensor to capture images of passing animals, representing verifiable and non-invasive records of the presence of a given species at a specified place and time. These simple records provide fundamental data on biodiversity that have proven invaluable to conservation.

Sorting camera trap images

2017 IEEE Global Conference on Signal and Information Processing (GlobalSIP), 2017
Camera trapping is used by conservation biologists to study snow leopards. In this research, we introduce techniques that sort camera trap images into sets with snow leopards and those without. We use Robust Principal Component Analysis, thresholding, and binary morphology to create motion templates.
