Photonic Engineering Enables All‐Passive Upconversion Imaging with Low‐Intensity Near‐Infrared Light

Advanced Functional Materials, EarlyView.
A passive upconversion imaging system enables the observation of scenes illuminated by low‐intensity incoherent near‐infrared light from 750 to 930 nm, by converting it into the visible without the use of external power. The upconverter is enabled by triplet–triplet annihilation in a bulk heterojunction, with absorption enhanced by plasmonic resonators

The search for biomarkers of facial eczema, following a sporidesmin challenge in dairy cows, using mass spectrometry and nuclear magnetic resonance of serum, urine, and milk : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Sciences at Massey University, Palmerston North, Manawatu, New Zealand [PDF]

, 2015
Facial eczema (FE) is a secondary photosensitisation disease of ruminants that is significant in terms of both its economic importance to New Zealand and its impact on animal welfare.

Efficient single frequency fibre lasers using novel photosensitive Er/Yb optical fibres

, 1997
Boron- and germanium-doped highly photosensitive cladding is used in a novel design to achieve photosensitive Er/Yb-doped fibers, permitting short, strong gratings (length ~1cm, reflectivity >99%) to be written without hydrogenation.

CHD2 variants are a risk factor for photosensitivity in epilepsy

Brain : a journal of neurology, 2015
Photosensitivity in epilepsy is common and has high heritability, but its genetic basis remains uncertain. Galizia et al. reveal an overrepresentation of unique variants of CHD2 — which encodes the transcriptional regulator ‘chromodomain helicase DNA ...

Microsphere Autolithography—A Scalable Approach for Arbitrary Patterning of Dielectric Spheres

Advanced Functional Materials, EarlyView.
MicroSphere Autolithography (µSAL) enables scalable fabrication of patchy particles with customizable surface motifs. Focusing light through dielectric microspheres creates well defined, tunable patches via a conformal poly(dopamine) photoresist. Nearly arbitrary surface patterns can be achieved, with the resolution set by the index contrast between ...

Photography’s Other Sensitivities

Media Theory
This article sets out to challenge the idea of photography as a medium that deals purely in the visible. Taking the example of the mid-twentieth-century British photography industry, this article considers photographic sensitivity as part of a sensory ...

Optical Sensor Based on a Single CdS Nanobelt

Sensors, 2014
In this paper, an optical sensor based on a cadmium sulfide (CdS) nanobelt has been developed. The CdS nanobelt was synthesized by the vapor phase transportation (VPT) method.

Investigation of thin film solar cells on CdS/CdTe base with different back contacts [PDF]

, 2010
The peculiarities of photo-electric processes in thin film CdS/CdTe solar cells (SC) with different back electrodes (Cu/Au, ITO, Cu/ITO) havebeen studied. As it was established by capacitance – voltage (C-V) characteristics, the potential barrier heights

Creation of backdoors in quantum communications via laser damage

, 2016
Practical quantum communication (QC) protocols are assumed to be secure provided implemented devices are properly characterized and all known side channels are closed. We show that this is not always true.

Adaptive 4D‐Printed Vascular Stents With Low‐Temperature‐Activated and Intelligent Deployment

Advanced Functional Materials, EarlyView.
Microarchitected coronary artery stents were fabricated using a polycaprolactone (PCL)‐based shape memory polymer (SMP) composite via projection micro‐stereolithography (PµSL) 4D printing. By incorporating diethyl phthalate (DEP) as a plasticizer, the thermal transition temperature (Ttran) was modulated to about 37°C, enabling rapid and autonomous ...
