Whale sharks, Rhincodon typus, aggregate around offshore platforms in Qatari waters of the Arabian Gulf to feed on fish spawn. [PDF]

PLoS ONE, 2013
Whale sharks, Rhincodon typus, are known to aggregate to feed in a small number of locations in tropical and subtropical waters. Here we document a newly discovered major aggregation site for whale sharks within the Al Shaheen oil field, 90 km off the ...

Highly variable basking shark (Cetorhinus maximus) diving behavior in the lower Bay of Fundy, Canada

Frontiers in Marine Science, 2022
Diving behavior in basking sharks, the largest obligate ram filter feeding planktivore, is highly dependent on their location. In the Bay of Fundy, where basking sharks congregate in the boreal summer and autumn, the sharks’ copepod prey are located deep

3D‐Printed Porous Hydroxyapatite Formed via Enzymatic Mineralization

Advanced Functional Materials, EarlyView.
Bone combines lightness, strength, and the ability to heal, inspiring new materials design. This work introduces a room‐temperature, enzyme‐mediated 3D printing method to create porous hydroxyapatite scaffolds. The process avoids energy‐intensive sintering, preserves bioactivity, and allows control over porosity and mineralization.

High‐Gain Ag2Te/MoS2 Hybrid Photodetectors for Short‐Wave Infrared Imaging

Advanced Materials, EarlyView.
A precision‐engineered short‐wave infrared image sensor based on a 0D/2D Ag2Te/MoS2 hybrid structure is demonstrated in this work. The device exploits photodoping at the nanoscale interface to achieve broadband detection from visible to infrared wavelengths with high responsivity and fast response.

Satellite tracking of juvenile whale sharks in the Sulu and Bohol Seas, Philippines [PDF]

PeerJ, 2018
The whale shark Rhincodon typus was uplisted to ‘Endangered’ in the 2016 IUCN Red List due to >50% population decline, largely caused by continued exploitation in the Indo-Pacific. Though the Philippines protected the whale shark in 1998, concerns remain

Broadband Directional Thermal Radiation with Asymmetric Femtosecond Laser‐Processed Surfaces

Advanced Optical Materials, EarlyView.
Femtosecond laser processing is used to scalably create self‐organized angled microstructures which exhibit highly directional emissivity that occurs for all polarizations. Laser parameters are tuned to alter the surface features, control the direction of emission, and enhance the directional emissivity. Electromagnetic modeling is performed to analyze
