Dimerisation of isobutene produces diisobutenes that can be hydrogenated to isooctane (2,2,4-trimethyl pentane). Isooctane can be used as a high octane gasoline component. The aim of this work was to study the selective production of diisobutenes through the dimerisation of isobutene on ion-exchange resin catalysts and to construct kinetic models for the reactions in the system for reactor desi...

The adsorption and the redox behaviour of thrombine binding aptamer (TBA) and extended TBA (eTBA) were studied using atomic force microscopy and voltammetry at highly oriented pyrolytic graphite and glassy carbon. The different adsorption patterns and degree of surface coverage were correlated with the sequence base composition, presence/absence of K and voltammetric behaviour of TBA and eTBA. ...

The adsorption and the redox behaviour of thrombin-binding aptamer (TBA) and extended TBA (eTBA) were studied using atomic force microscopy and voltammetry at highly oriented pyrolytic graphite and glassy carbon. The different adsorption patterns and degree of surface coverage were correlated with the sequence base composition, presence/absence of K(+), and voltammetric behaviour of TBA and eTB...

A novel ultrasensitive biosensor was constructed by the [TBA]2[Ni(mnt)2]/graphene (mnt = maleonitriledithiolate) composite film for the detections of glutamate and alanine aminotransferase (ALT). The [TBA]2[Ni(mnt)2] nanocubes with a dimension of 500 nm were in-situ crystallized on the surface of Au electrode modified using thiol graphene in advance. Due to the synergistic effect

We put forward an idea that the boundary entropy associated with integrable massless flow of thermodynamic Bethe ansatz (TBA) is identified with tachyon action of boundary string field theory. We show that the temperature parametrizing a massless flow in the TBA formalism can be identified with tachyon energy for the classical action at least near the ultraviolet fixed point, i.e., the open str...

We describe design and testing of an induction cell with modulator for the Relativistic Klystron Two-Beam Accelerator (RK-TBA) concept, an option for the power source for the Next Linear Collider (NLC). FM Technologies has designed and built a prototype induction accelerator, which we call a re-accelerator, for a joint LLNL/LBNL TBA technology test-bed experiment.

A study is presented of the nanomechanical phenomena experienced by nanoparticle-conjugated biomolecules. A thermodynamic framework is developed to describe the binding of thrombin-binding aptamer (TBA) to thrombin when the TBA is conjugated to nanorods. Binding results in nanorod aggregation (viz. directed self-assembly), which is detectable by absorption spectroscopy. The analysis introduces ...

Regulation of microtubule dynamics underlies many fundamental cellular mechanisms including cell division, cell motility, and transport. In neurons, microtubules play key roles in cell migration, axon outgrowth, control of axon and synapse growth, and the regulated transport of vesicles and structural components of synapses. Loss of synapse and axon integrity and disruption of axon transport ch...

We use new TRACE data to investigate the liquidity and pricing of agency mortgagebacked pass-through securities. We distinguish between two trading channels -a To-BeAnnounced (TBA) forward delivery market and a specified-pool market. Institutional specified-pool traders in the deep end of the market have easy access to the TBA market, while retail specified-pool traders in the shallow end of th...

The purpose of the study was to determine the effect of trenbolone acetate (TBA) on performance, plasma lipid metabolites, and carcass characteristics of growing ram and ewe lambs in two separate experiments. Treatments consisted of 1) a control, no implants, and 2) a TBA implant (60 mg of Finaplix; Hoechst-Roussel Agri-Vet). Twelve Rambouillet cross ram lambs (average 19.9 kg BW; Exp. 1) and 1...
