Satellite Imagery for Monitoring and Mapping Soil Chromium Pollution in a Mine Waste Dump

open access: yesRemote Sensing, 2021
Weathering and oxidation of sulphide minerals in mine wastes release toxic elements in surrounding environments. As an alternative to traditional sampling and chemical analysis methods, the capability of proximal and remote sensing techniques was ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Opportunities and pitfalls in (sub)diffuse reflectance spectroscopy [PDF]

open access: yes, 2022
For a long time, steady-state reflectance spectroscopy measurements have been performed so that diffusion theory could be used to extract tissue optical properties from the reflectance.

Optical Methods for Non-Invasive Determination of Skin Penetration: Current Trends, Advances, Possibilities, Prospects, and Translation into In Vivo Human Studies

open access: yesPharmaceutics, 2023
Information on the penetration depth, pathways, metabolization, storage of vehicles, active pharmaceutical ingredients (APIs), and functional cosmetic ingredients (FCIs) of topically applied formulations or contaminants (substances) in skin is of great ...

Modelling stem cell differentiation related processes—A practical overview for biologists

open access: yesFEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

AHS2005: The 2005 airborne imaging spectroscopy campaign in the Millingerwaard, the Netherlands [PDF]

open access: yes, 2008
The Millingerwaard was one of the first nature rehabilitation projects for river floodplains in the Netherlands. It therefore serves as an example project for other floodplain rehabilitation projects.

Estimating the irradiance spectrum from measurements in a limited number of spectral bands [PDF]

open access: yes, 2006
Accurate measurement and characterisation of fluctuations in the irradiance environment is important for many areas of optical remote sensing. This paper describes a method of estimating spectral irradiance over the region 400 – 1000 nm from the radiance

Cryogenic reflectance spectroscopy under high vacuum conditions for outer planets exploration [PDF]

open access: yes, 2023
Recently selected Venus missions, such as NASA's VERITAS, ESA's EnVision, and DAVINCI, are all equipped with instruments that focus on the 1 μm region in their payloads.

Simulating Imaging Spectroscopy in Tropical Forest with 3D Radiative Transfer Modeling

open access: yesRemote Sensing, 2021
Optical remote sensing can contribute to biodiversity monitoring and species composition mapping in tropical forests. Inferring ecological information from canopy reflectance is complex and data availability suitable to such a task is limiting, which ...
