We present a fully-printable method to embed interactive information inside 3D printed objects. The information is invisible to the human eye and can be read using thermal imaging after temperature transfer through interaction with the objects. Prior methods either modify the surface appearance, require customized devices or not commonly used...

LaBr<sub>3</sub>:Ce<sup>3+</sup> is a compound with excellent scintillation properties, but its ultraviolet emission does not match well with the detection efficiency curves of silicon based photodetectors. In this work, Sm<sup>2+</sup> is studied as an activator for LaBr<sub>3</sub> as its near-infrared emission can be detected with close to...

<b>OBJECTIVE </b>This study aims to compare non-invasive real-time optical imaging and measuring methods for the quantification of microcirculation of organs during normothermic machine perfusion (NMP). This could help to determine which method is most promising for further development towards a clinical objective transplantability assessment...

Fast energy transfer from Yb<sup>2+</sup> to Sm<sup>2+</sup> is a requirement when using Yb<sup>2+</sup> as a sensitiser for Sm<sup>2+</sup> emission for near-infrared scintillator applications. This cannot be achieved through dipole-dipole interactions due to the spin-forbidden nature of the involved Yb<sup>2+</sup> transition, making the...

Information storage in vivo will lead to next-generation identification and security authentication. Here, an information storage method was proposed for in vivo application by using a pair of lanthanide-doped nanoprobes (NdNPs and ErNPs) with orthogonal emissions in the second near-infrared window. The information is stored in different...

Introduction Near-infrared fluorescence (NIRF) imaging is a relatively novel development in colorectal liver metastases (CRLM) surgery which has proven to be an added value for the detection of new lesions and surgical guidance. However, new possibilities of NIRF imaging in CRLM surgery are yet to be explored. The fluorescent rim of indocyanine...

Despite a large number of in-situ missions, only VeGa-2 provided the high-resolution thermal measurements of the deep atmosphere of Venus below 12 km and they indicated a highly unstable layer below 7 km altitude. Lebonnois and Schubert (2017) tried to explain the VeGa-2 measurements by introducing a theory of a composition gradient in the deep...

Background Current near-infrared spectroscopy (NIRS)-based systems for continuous flap monitoring are highly sensitive for detecting malperfusion. However, the clinical utility and user experience are limited by the wired connection between the sensor and bedside console. This wire leads to instability of the flap-sensor interface and may...

The use of near-infrared (NIR) spectroscopy in wastewater treatment has continuously expanded. As an alternative to conventional analytical methods for monitoring constituents in wastewater treatment processes, the use of NIR spectroscopy is considered to be cost-effective and less time-consuming. NIR spectroscopy does not distort the...

The window layers limit the performance of silicon heterojunction (SHJ) solar cells with front and back contacts. Here, we optimized tungsten-doped indium oxide (IWO) film deposited by radio frequency magnetron sputtering at room temperature. The opto-electrical properties of the IWO were manipulated when deposited on top of thin-film silicon...

The JUICE (JUpiter ICy moons Explorer) mission by ESA aims to explore the emergence of habitable worlds around gas giants and the Jupiter system as an archetype for gas giants. MAJIS (Moons and Jupiter Imaging Spectrometer) is the visible to near-infrared imaging spectrometer onboard JUICE which will characterize the surfaces and exospheres of...

Background: Non-invasive monitoring of cerebral tissue oxygen saturation (rcSO<sub>2</sub>) during transition is of growing interest. Different near-infrared spectroscopy (NIRS) techniques have been developed to measure rcSO<sub>2</sub>. We compared rcSO<sub>2</sub> values during the immediate transition in preterm neonates measured with...

The standard of clinical care in many pediatric and neonatal neurocritical care units involves continuous monitoring of cerebral hemodynamics using hard-wired devices that physically adhere to the skin and connect to base stations that commonly mount on an adjacent wall or stand. Risks of iatrogenic skin injuries associated with adhesives...

In many aspects measurement of the α/β ratio has advantages over other methods. It provides higher precision and higher density of excitation than is available with Compton or photoelectric effect electrons. It has been shown that the α/β ratio follows the same trends and patterns as previously found for nonproportionality of electron/ gamma...

Methodology <br/>Agriculture is an important sector to provide in our needs. Since 2000, the arable land per farmer increased with 66%. To help farmers managing their increasing amount of arable land, it is important to develop new techniques in example based on remote sensing data. One of the key parameters for agricultural management is the...

This report showcases the development of a product to aid the venipuncture procedure. Venipuncture is a procedure where intravenous access is obtained for several purposes. Finding a location and vein to insert the needle is the most important step of this procedure. Nearly 90% of hospitalised patients have to undergo the procedure. Despite...

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...

Perlite products are used as a filter aid in the food industry. For such applications, the purity of the material is one of the most significant parameters of control. Early detection of heavy metals is therefore of great industrial interest. In this study, a sensor-based approach for chemical and mineralogical characterization enabled the...
