Aqueous biphasic catalysis is a convenient approach to convert organic, partially soluble molecules in water. However, converting more hydrophobic substrates is much more challenging as their solubility in water is extremely low. During the past ten years, substantial progress has been made towards improving the contact between hydrophobic substrates and a hydrophilic transition-metal catalyst....

This paper argues that Information Technology (IT) needs to be demystified, through critical consciousness, for educators to focus on IT as a means to enhance learning. It goes on to define the technical, sociohistorical and political-ideological levels of IT and to identify four theoretical constructs: tutorial, machine-as-human, tool kit and catalyst. Pervading these constructs is the underst...

Magnetizations and magnetic moments of free cobalt clusters Co(N) (12 < N < 200) in a cryogenic (25 K < or = T < or = 100 K) molecular beam were determined from Stern-Gerlach deflections. All clusters preferentially deflect in the direction of the increasing field and the average magnetization resembles the Langevin function for all cluster sizes even at low temperatures. We demonstrate in the ...

This study is the first attempt to large-scale energy-efficient production of nanomagnetic Ni/NiO composites by using autocombustion based on leaves or extract corchorus olitorius. The as synthesized product can be characterized XRD, SEM, TEM and EDX techniques. results confirm that materials consisted entirely well crystalline Ni NiO phases. crystallinity both enhanced increasing amount Howeve...

The super-Brownian motion X % in a super-Brownian medium % constructed in DF96a] is known to be persistent (no loss of expected mass in the longtime behaviour) in dimensions one ((DF96a]) and three ((DF96b]). Here we ll the gap in showing that persistence holds also in the critical dimension two. The key to this result is that in any dimension (d 3); given the catalyst, the variance of the proc...

We have demonstrated the capabilities of scanning microwave microscopy (SMM) technique for measuring ferromagnetic resonance (FMR) spectra in nanometric areas magnetic samples. The is evaluated using three different samples, including a yttrium iron garnet (YIG) polycrystalline bulk sample and thick YIG film grown by liquid phase epitaxy (LPE). Patterned permalloy (Py) micromagnetic dots been c...

Complex cell behaviours are triggered by chemical ligands that bind to membrane receptors and alter intracellular signal transduction. However, future biosensors, medical devices and other microtechnologies that incorporate living cells as system components will require actuation mechanisms that are much more rapid, robust, non-invasive and easily integrated with solid-state interfaces. Here we...

UNLABELLED The objective of this work was to examine the effects of magnet distance (and by proxy, field strength) on nanomagnetic transfection efficiency. METHODS non-viral magnetic nanoparticle-based transfection was evaluated using both static and oscillating magnet arrays. RESULTS Fluorescence intensity (firefly luciferase) of transfected H292 cells showed no increase using a 96-well Nd...
