ToF-SIMS has been used in the analysis of latent fingerprints (dactyloscopy) with a view to use in forensic and biomedical applications. Szynkowska et al have demonstrated that SIMS can be employed to produce images of whole fingerprints on inorganic surfaces such as steel, brass and glass (1). We demonstrate the detection of a range of exogenous materials in fingerprints including industrial l...

Chemical imaging of single cells at the molecular level is important in capturing biological dynamics. Single cell correlative imaging is realized between super-resolution microscopy, namely, structured illumination microscopy (SIM), and time-of-flight secondary ion mass spectrometry (ToF-SIMS) using a multimodal microreactor (i.e., System for Analysis at the Liquid Vacuum Interface, SALVI). SI...

The effects of baking on the mechanical properties and fracture characteristics of low-carbon boron (10B21) steel screws were investigated. Fracture torque tests and hydrogen content analysis were performed on baked screws to evaluate hydrogen embrittlement (HE) susceptibility. The diffusible hydrogen content within 10B21 steel dominated the fracture behavior of the screws. The fracture torque ...

Aviation training in the immersive Virtual Reality (VR) world has power to overcome physical constraints, presenting cues and stimuli that would not be available flight, nor a two-dimensional (2D) environment. This gives VR powerful potential as simulation tool for learning complex skills maneuvers cockpit. study evaluated effectiveness of simulations compared traditional 2D desktop teaching ab...

FIB-based instruments play an ever more important role in materials science and also in life science. While such FIB-based instrumentation is an ideal tool for high resolution imaging (2D and 3D imaging) and nanofabrication (nanomaching, nanodeposition, specimen preparation), its analysis capability is currently limited. By contrast, Secondary Ion Mass Spectrometry (SIMS) is an extremely powerf...

The adsorption of bovine serum albumin (BSA), immunoglobulin G (IgG) and fibrinogen (Fgn) on fluorinated selfassembled monolayers have been studied using time of flight secondary ion mass spectrometry (ToF-SIMS) and Spectroscopic Ellipsometry (SE). The objective of the work has to establish the utility of ToF-SIMS for the determination of the amount of protein adsorbed on the surface. Quantific...

BACKGROUND Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS) is a surface sensitive mass spectrometry technique with potential strengths as a method for detecting enzymatic activity on solid materials. In particular, ToF-SIMS has been applied to detect the enzymatic degradation of woody lignocellulose. Proof-of-principle experiments previously demonstrated the detection of both lignin-d...

A critical problem in building an information mediator is how to translate a domain-level queries into an e cient query plan for accessing the required data. We have built a exible and e cient information mediator, called SIMS. SIMS takes a domain-level query and dynamically selects the appropriate information sources based on their content and availability, generates a query access plan that s...
