Bed‐level tools for monitoring erosion and accretion patterns: Flume validation and field testing

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Monitoring short‐term changes in surface sediment elevation is fundamental to understanding erosion, transport, and deposition dynamics in shallow coastal environments. However, commonly used field approaches, such as horizontal markers, sediment erosion tables, subsurface sediment plates, or erosion pins, are not always cross‐validated under ...

From Planar to 3D Nanophotonic Lenses: Advancing Design, Fabrication, and Applications

open access: yesLaser &Photonics Reviews, EarlyView.
Three‐dimensional nanophotonic lenses are enabled by an integrated workflow that links design parameterization, full‐wave electromagnetic simulation, computational optimization, and freeform fabrication. This Review summarizes how these tools expand optical design freedom beyond a single patterned plane by enriching the local meta‐atom response and ...

Additions to the Acanthaceae of the Flora of Tropical East Africa: two new species from northern Kenya

open access: yesNordic Journal of Botany, EarlyView.
The new species Barleria kulalensis I.Darbysh. & Q.Luke and Dicliptera huriensis I.Darbysh. & Q.Luke are described and illustrated and their extinction risk is assessed provisionally. The former is based on Barleria sp. G of the Flora of Tropical East Africa (FTEA), with recent field observation and collection of this species from the foothills of ...

Effect of Carbon Nanotubes Incorporation on the Properties of a Photopolymer Resin Used in Vat Photopolymerization

open access: yesPolymer Composites, EarlyView.
Preparation and experimental results of carbon nanotube/photopolymer resin nanocomposites fabricated by 3D printing. ABSTRACT This work examines the effect of the incorporation of carbon nanotubes (CNTs) into a photopolymer resin for the fabrication of nanocomposites via additive manufacturing (AM), using the masked stereolithography technique (MSLA ...
