	abstract = {Elastomeric proteins are molecular springs that confer excellent mechanical properties(1-5) to many biological tissues and biomaterials. Depending on the role performed by the tissue or biomaterial, elastomeric proteins can behave as molecular springs(1,2,6,7) or shock absorbers(3-5,8-10). Here we combine single-molecule atomic force microscopy and protein engineering techniques to create elastomeric proteins that can switch between two distinct types of mechanical behaviour in response to the binding of a molecular regulator. The proteins are mechanically labile by design and behave as entropic springs with an elasticity that is governed by their configurational entropy. However, when a molecular regulator binds to the protein, it switches into a mechanically stable state and can act as a shock absorber. These engineered proteins effectively mimic and combine the two extreme forms of elastic behaviour found in natural elastomeric proteins, and thus represent a new type of smart nanomaterial that will find potential applications in nanomechanics and material sciences.},

	abstract = {Titanium boron nitride films with a functionally graded underlayer of Ti/TiN were grown at low temperatures ( < 200 degreesC) on a silicon substrate using ion beam assisted deposition. These coatings had a total thickness of 1.5 +/- 0.2 mum. They were characterized using X-ray diffraction (XRD), atomic force microscopy (AFM), X-ray photoelectron spectroscopy (XPS) and spectroscopic ellipsometry. The primary phases in the film were identified using XRD and were found to be in agreement with the equilibrium phase diagram. The surface morphology and nanocrystalline nature of the coating were deduced using AFM. The chemical and phase composition was determined from XPS measurements. The refractive indices were deduced from the investigation of the ellipsometric data and were subsequently correlated to the elemental and phase composition. The hardness and elastic modulus were measured and were found to depend on phase composition. The films were implanted with carbon ions. XPS measurements revealed that new phases formed at the surface as a result of carbon implantation, namely, titanium carbide and elemental carbon. Carbon implantation significantly reduced the friction coefficient from 0.5-0.7 to 0.15-0.25. The hardness of the films decreased by 2-5\%. (C) 2003 Elsevier B.V. All rights reserved.},

	abstract = {A series of monolithic and multilayer coatings of chromium nitride with various compositions and architectures were deposited at low temperatures (< 200 degreesC) on silicon substrates using ion-assisted reactive magnetron sputtering. All coatings had a total thickness in the 1.5 +/- 0.3 mum range. The multilayer coatings were designed such that their period and CrN fraction varied in the range 30-150 nm and 0.50-0.93, respectively. Real-time in situ ellipsometry was used to monitor and control the deposition process. The deposited coatings were characterized post-deposition using X-ray diffraction (XRD): Rutherford backscattering (RBS), X-ray photoelectron spectroscopy (XPS), and spectroscopic ellipsometry (SE). The primary chromium nitride phases (Cr2N and CrN) in the films were identified using XRD. The chemical composition of selected samples was determined from RES and XPS measurements. The phase composition of the deposited layers was deduced from the analysis of the SE data. The mechanical properties of the coatings were evaluated using a nanoindenter. The measured hardness values were in excess of 20 GPa. The results of the different characterization and testing techniques were correlated and follow-up work on this project suggested.
