Constructing near-infrared light (NIR) light-enhanced room temperature gas sensors is becoming more promising for practical application. In this study, learning from the structure and photosynthetic process of chlorophyll thylakoid membranes in plants, the first “Thylakoid membrane” structural formaldehyde (HCHO) sensor is constructed by...

A novel method for space object identification is proposed, based on full Stokes spectropolarimetry in the visible and near-infrared wavelength range. Space objects that have been previously detected and are illuminated by the sun can be observed with a telescope to simultaneously obtain intensity, spectra, and polarimetry, and compose light...

Background and aims: Atherosclerotic plaque onset and progression are known to be affected by local biomechanical factors. While the role of wall shear stress (WSS) has been studied, the impact of another biomechanical factor, namely mechanical wall stress (MWS), remains poorly understood. In this study, we investigated the association of MWS...

Today, one of the major goals of modern astronomy is the search for other habitable worlds and the presence of life on them. Crucial in this search is the atmospheric characterisation of small, rocky planets orbiting in the habitable zone around solar type stars. The LIFE initiative will be able to perform atmospheric characterisation of a...

To improve efficiency, dairy farmers monitor the inputs and outputs of their cows based on data collected by sensors. Currently the main sources for this data are the given food and information about the milk (composition and volume). This data helps the farmer make better decisions regarding animal welfare and feeding practices. However, one of...

Starting from the 1950s, plastic has found its way into many aspects of life; from packaging to transportation and construction. The annual global plastic production was estimated to be 330 million metric tons in 2017 and will be doubled within 20 years if the current growth rate persists. In Europe, packaging accounts for 40% of the annual...

The idea for this project was created by two Urologists at the Erasmus MC in Rotterdam. The design goal was to develop a diagnostic device that can be used to measure nocturnal (i.e. nightly) erections. The current device used to measure nocturnal erections was developed in the 1980s. There is a need for a modern tool that can be used in the...

An innovative route for plastics recycling is proposed, based on a combination of a logarithmic sorting process and colour plus high-resolution near-infrared (NIR) sensors. Although counterintuitive, it is shown that such a technology could sort clean flakes from rigid packaging waste into a very large number of different plastic grades with...

Near-infrared (NIR) and short-wavelength infrared (SWIR) hyperspectral imagery can be used to detect certain alteration minerals. At epithermal deposits, the formation of alteration minerals is, in theory, related to the mineralisation of gold and silver. In order to provide foundations for developing sensor-based sorting applications at a...

Diatomite is a white and soft sedimentary rock made of the skeletal remains of diatoms. Diatoms are unicellular organisms that belong to the algae and have a skeleton made of opal (hydrated silica). The ore in the deposit in Elche de la Sierra (Spain) is primarily made of these diatoms but there is also calcium carbonate present in the ore. The...

In the presented study test work was performed with near-infrared hyperspectral imagery (NIR-HI) on 36 ore samples from a South-American epithermal Au-Ag mine. The aim of the test work was to investigate if NIR-HI provides information about the alteration mineralogy of samples that can be used to predict their economic value. Mineral...

The use of sensor based technology to distinguish in real-time between economic and sub-economic material could contribute to the optimization of the technology and economics behind mining operations. The goal of this study is to contribute to the development of a near-infrared sensor-based pre-sorting ore classification model. This study is...

Los Bronces is an open pit mine located on a large porphyry copper-molybdenum deposit near Santiago, Chile. Annual production is around 240 000 tonnes of copper and 2 700 tonnes of molybdenum. The extracted ore has a relatively low average copper grade of around 0.6%. This results in relatively high processing costs and creates the need to...

An imager for optical tomography was designed based on a detector with 128x128 single-photon pixels that included a bank of 32 time-to-digital converters. Due to the high spatial resolution and the possibility of performing time resolved measurements, a new contact-less setup has been conceived in which scanning of the object is not necessary....
