Ultrananocrystalline diamond coated implants for enhanced osseointegration [PDF]
BioDiscovery, 2017 Osteoporosis causes bones to become weak and brittle. It is known that the alterations in bone metabolism associated to osteoporosis can impair bone healing around implants and affect their osseointegration.

Nanostructured plasmonic metapixels [PDF]
Scientific Reports, 2017 AbstractState-of-the-art pixels for high-resolution microdisplays utilize reflective surfaces on top of electrical backplanes. Each pixel is a single fixed color and will usually only modulate the amplitude of light. With the rise of nanophotonics, a pixel’s relatively large surface area (~10 μm2), is in effect underutilized.

Imaging high-speed friction at the nanometer scale
Nature Communications, 2016 It has been a challenge to characterize microscopic origins of friction at high velocities. Here authors extend atomic force microscopy to develop a dynamic technique combining force sensitivity and spatial resolution and able to probe, at each image ...

A circular dielectric grating for vertical extraction of single quantum dot emission [PDF]
, 2011 We demonstrate a nanostructure composed of partially etched annular trenches in a suspended GaAs membrane, designed for efficient and moderately broadband (approx. 5 nm) emission extraction from single InAs quantum dots.

, 2020 Chapter 8 Nanostructured Steels Nanostructured metals with grain sizes smaller than 100 nm usually exhibit strengths which can be more than twice higher than their coarse-grained counterparts. The “smaller is stronger” effect is generally understood in terms of the Hall-Petch effect of grain size strengthening, or the capability of grain ...

Fabrication, modeling, and characterization of form-birefringent nanostructures [PDF]
, 1995 A 490-nm-deep nanostructure with a period of 200 nm was fabricated in a GaAs substrate by use of electron-beam lithography and dry-etching techniques.
