Electronic controls cannot always compensate for the destabilization of a poorly designed vehicle caused by tire delamination. Axle tramp caused from rubber strips on the track showed axle skate [1]. Further research, reported at ESV 2007 [2] demonstrated that lumps on a single rear tire caused 15+ degrees/g of oversteer. The Engineering Institute has shown that the process of tire delamination...

Acid fuels the motion of a threaded ring A central goal in the construction of molecular-scale machines is the efficient achievement of oneway motion. Erbas-Cakmak et al. developed a class of machines that transmit pH changes into the two-stage guided motion of molecular rings threaded on a linear or cyclic axle. The design relies on temporary blocking groups and landing sites along the axle th...

A cyclodextrin ring was face-selectively transferred between two stations linked by a 2-methylpyridinium group on an axle molecule.

There is a need for vehicles to maneuver when there are traffic jams, overcome narrow streets and various obstacles. This leads increased requirements dynamism maneuverability of vehicles.
 The authors present the results development research steering control vehicle, which provides maneuverability. Such circumstances significantly affect increase in wheeled vehicles, including tractors, u...

[2]- and [3]-rotaxanes with a tetraphenoxy perylene diimide core were synthesized. Hydrogen bonding between the wheel and the imide changes the optical properties of the perylene chromophore: the absorption and fluorescence spectra are red-shifted. The decay times of the rotaxanes are shorter in comparison with that of the axle. Single molecule fluorescence measurements reveal relatively narrow...

Over the past twenty years; road traffic (both passenger and freight) has grown significantly in Pakistan. Higher axle loads and repetitions have resulted in premature rutting of flexible pavements. Rutting, in the form of shear flow is a typical distress that mainly attributed to increased tire pressure, high temperature and heavy axle loads. Consequently, National Highway Authority (NHA), Pak...

We report a diverted route to [1]rotaxane and tris-branched [1]rotaxane that are devoid of any efficient template and which could not be obtained by classical straightforward strategies. The described chemical route relies on the utilization of a "macrocycle transporter", which is able first to bind a macrocycle, second to link temporarily a triazolium-containing molecular axle, and third to de...

A new [2]rotaxane host system containing nitro-isophthalamide macrocycle and polyether functionalised pyridinium axle components is prepared via clipping and stoppering synthetic methodologies using chloride anion templation. After removing the chloride anion template, (1)H NMR titration experiments reveal the unique interlocked host cavity to be highly selective for binding chloride and bromid...

Abstract Infrastructure worldwide is facing the challenge of aging bridges and increasing traffic loads. Prolonged serviceability safety these structures can be enabled by Structural Health Monitoring (SHM) methods. Knowledge actual operating loads critical for evaluation remaining service life. However, direct measurement challenging requires a significant financial investment. Bridge Weigh‐In...
