Thermally driven visco-elastic measurement technique via spectral variations in scanning probe microscopy cantilevers
… range and resolution required to quantify the visco-elastic fluid properties in the interfacial regime. With the availability and versatility of AFMs and the mounting models and data related to the performance of SPM probes in a fluid environment, the AFM is an attractive platform to exploit. …

Jatropha curcas oil as a bio-based rejuvenating agent for reclaimed asphalt pavement mixtures
… and mixture were investigated via physical properties test, bleeding test, diffusion test, rheological properties, chemical properties and mixtures performance test, respectively. The test results show that the incorporation of JCO with virgin binder decreased the viscosity and improved the …

Microgels at oil-water interfaces
… of stabilization is mainly controlled by the visco-elastic properties of the interfacial microgel layer.

An Acoustic Pulse Electro-Kinetic Sensor
… is a function of the charge distribution and the visco-elastic properties of the fluid at the interface. Two distinct electro-kinetic effects are identified and characterized, referred to as Double-Layer Compression (DLC) and the Parallel Vibration Potential (PVP). A DLC signal is generated when …

How do trees die following low intensity fires: Exploring the hydraulic death hypothesis
… of direct xylem vessel deformation due to the visco-elastic properties of xylem walls (lignin). In order to determine the relative importance of each proposed mechanism, stems of Kiggelaria africana and Eucalyptus cladocalyx were exposed to 70 and 100„aC in two treatments designed to isolate …

Design, synthesis and characterization of photocage molecules for light-activated release: Applications in polymer chemistry and phototherapeutics
… of new BODIPY photocages, advancing the properties of those photocages with structural modifications and extending the scope of those photocages with different leaving groups uncaging for better activity and releasing ability within the living cells. In chapter 2, a new class of BODIPY …

An observational study to assess coagulation abnormalities in patients with elevated levels of urea and/or creatinine secondary to renal failure, presenting for renal biopsy – challenging conventional testing using visco-elastic testing
… as its breakdown. TEG® and ROTEM® assesses the visco-elastic properties of blood in vitro to define in vivo coagulability. The standard of care in our institution to assess the bleeding risk in patients with renal failure (defined by a raised urea and/or creatinine level) presenting for a renal …

Investigation of biological macromolecules using atomic force microscope-based techniques
… assemblies. A novel approach to investigate the visco-elastic behavior of biomolecules under force was established, using dextran as an example. While a molecule tethered between a solid support and the cantilever tip was stretched at a constant velocity, the thermally driven oscillation of the …

Modelling and Simulation of the Nonlinear Dynamics of Arrays of Coupled Filaments for Robot Walkers
… of rigid filaments that are coupled through visco-elastic lumped elements at the base. These filaments emulate hair-like structures idealized as inverted pendulums, capturing certain characteristics of cilia-like structures that are relevant for the locomotion. Mechanical coupling is achieved …

Thromboelastography in the assessment of coagulation changes in peripheral vascular disease
… (TEG), a technique which exploits the visco-elastic properties of a blood clot as it forms, retracts or lyses (breaks down) using a small volume of whole blood. Validation of TEG technique employing citrated whole blood (CWB) and heparinase modified (hepTEG) methods and standardisation …
