"Fragile" glassy materials, which include most polymeric materials and organic liquids, exhibit a steep and super-Arrhenius dependence of relaxation time with temperature upon the glass transition and have been extensively studied. Yet, a full understanding of strong glass formers that exhibit an Arrhenius dependence on temperature is still lacking. In this work, we have investigated the glassy...

Graphs are a natural fit for modeling concepts used in solving diverse problems in science, commerce, engineering, and governance. Responding to the variety of graph data and algorithms, many parallel and distributed graph-processing systems exist. However, until now these platforms use a static model of deployment: they only run on a pre-defined set of machines. This raises many conceptual and...

A Ni-free ?-Ti alloy comprising Ti-40Hf-13Nb-4.5Sn (wt.%) was developed as a substitute for NiTi (nitinol) alloys in medical applications. It is found that, due to significant Stress Induced Martensite (SIM) transformation and large lattice strain, combined with good strength stability, this showed stable super-elastic deformation behavior at room temperature. Total recoverable strain of 5.3 % ...

Interfacial Assembly of Graphene Oxide In article number 2101659, Milad Kamkar, Uttandaraman Sundararaj, and co-workers demonstrate the great performance graphene oxide (GO) nanosheets at interface oil water. Super elasticity with highest ever reported interfacial storage modulus oil/water is achieved in presence only 0.04 vol.% GO, enabling sculpting water any desired shape.

The cancellous bone effective properties relations are analysed on multiscale across two aspects; properties of representative volume element on micro scale and statistical measure of trabecular trajectory orientation on mesoscale. Anisotropy of the microstructure is described across fabric tensor measure with trajectory orientation tensor as bridging scale connection. The scatter measured data...

This paper describes a fast technique for dressing virtual humans with different pieces of clothing. It exploits a mass-spring cloth model but applies a new velocity modification approach to overcome its super-elasticity. The algorithm for cloth-body collision detection and response is based on image-space interference tests, unlike most of the existing ones, which use objectspace checks. The m...

Nanomechanics and structural design of MEMS are intimately tied together. As mechanical properties of hard materials are found to be strongly sample-size dependent, new criteria are in demand for size-dependent structural analysis and design of MEMS components. The paper offers a critical survey of some of the most interesting and challenging advances in nanomechanics of metals from a MEMS desi...

The nickel-titanium alloy Nitinol has been used in the manufacture of endodontic instruments in recent years. Nitinol alloys have greater strength and a lower modulus of elasticity compared with stainless steel alloys. The super-elastic behaviour of Nitinol wires means that on unloading they return to their original shape following deformation. These properties are of interest in endodontology ...
