We present a newly developed methodology using computer-readable fiducial markers to allow images from multiple imaging modalities to be registered automatically. This methodology makes it possible to correlate images from many surface imaging techni

Rates of peptide bond hydrolysis and other diagenetic reactions are not favourable for Mesozoic protein survival. Proteins hydrolyse into peptide fragments and free amino acids that, in open systems such as bone, can leach from the specimen and be fu

White fibers from a Late Cretaceous dinosaur Shuvuuia deserti stained positive for β-keratin antibodies in a 1999 paper, followed by many similar immunological claims for Mesozoic protein in bones and integument. Antibodies recognize protein epitope

Predator-prey dynamics are an important evolutionary driver of escalating predation mode and efficiency, and commensurate responses of prey. Among these strategies, camouflage is important for visual concealment, with countershading the most universa

Carbonation of hydrous minerals such as calcium hydroxide (Ca(OH)2) is an important process in environmental and industrial applications for the construction industry, geological disposal repositories for nuclear waste, and green technologies for car

One factor which may limit the scale of application of oxide superconductors is their intrinsic instability when in contact with air containing water vapour. All families of these materials are to some extent subject to surface degradation reactions

RATIONALE Secondary ion mass spectrometry (SIMS) is an important technique for the characterization of proteins at surfaces. However, interpretation of the mass spectra is complicated owing to confusion with peaks from contaminants and the substrate

Despite the benefits of multivariate analysis methods, many challenges remain with their robust applications to real-life samples relevant to industry. Here, we use hair fibres pre-treated with a multi-component formulation to investigate different m

A detailed study is presented of the effects of surface topography on ToF-SIMS images, using experimental results from model conducting fibres, consisting of gold wires of diameters in the range of 33–125 μm mounted onto silicon wafers, and ion op
