The regularities of chromatographic retention and separation enantioselectivity the selected β-blockers (propranolol, pindolol, alprenolol, atenolol, oxprenalol, metoprolol, clenbuterol, sotalol, pronethalol, salbutamol, labetalol) were studied with eight chiral stationary phases (CSPs) in polar ionic mode (PIM) elution system. A range novel CSPs was prepared by immobilisation macrocyclic glyco...

Tailoring materials to obtain unique, or significantly enhanced material properties through rationally designed structures rather than chemical constituents is principle of metamaterial concept, which leads to the realization of remarkable optical and mechanical properties. Inspired by the recent progress in electromagnetic and mechanical metamaterials, here we introduce the concept of ferroele...

As socie ty becomes more comfortable discussing genetics and its related ethics, a new technology is blossoming in the background. Nanotechnology may speak the same societal language as does genetics, in that both technological movements involve tiny science and large imagination. In a way, it is natural—and almost inevitable—that the genetic revolution and the nanotechnology revolution be comp...

In this work, we present new results about the non-enzymatic detection of lindane by using CuO-MnO2 hierarchical nano-microstructures. The linear range for the determination of lindane is up to 700 μM with a limit of detection of 4.8 nM, which is much lower than for other non-enzymatic lindane sensors.

The mode-specific vibrational energy relaxation of the amide I' and amide II' modes in NMA-d(1)/(D(2)O)(n) (n = 0-3) clusters were studied using the time-dependent perturbation theory at the B3LYP/aug-cc-pvdz level. The amide modes were identified for each cluster based on the potential energy distribution of each mode. The vibrational population relaxation time constants were derived for the a...

The mechanism of the vasodilator effect of procaine amide in dogs was investigated in isolated gracilis muscle and hindpaw perfused at constant flows with arterial blood. Inhibition of sympathetic ganglionic transmission contributed predominantly to the vasodilatation in muscle that accompanied intravenous administration of procaine amide (20 mg/kg). In contrast, comparable amounts of procaine ...

Plasmonic nanostructures with a negative Poisson ratio are demonstrated, having the unusual mechanical property of auxetics to expand laterally when being stretched. Using nanomembrane technology, auxetics are shrunk by orders of magnitude, giving simultaneous access to optical properties of plasmonic metamaterials, as well as auxetic mechanical properties on the nanoscale.
