Spin-crossover compounds are becoming increasingly popular for device and sensor applications, and in soft materials, that make use of their switchable colour, paramagnetism and conductivity. The de novo design of new solid spin-crossover compounds with pre-defined switching properties is desirable for application purposes. This challenging problem of crystal engineering requires an understandi...

We demonstrate a simple waveplate analyzer to characterize linear retarders using magneto-optic (MO) polarization rotators. The all-solid state device can provide highly accurate measurements for both the retardation of the waveplate and the orientation of optical axes simultaneously.

a simple, efficient and clean procedure has been developed for the cleavage of imines c=n bond. deprotection of imines to their parent carbonyl and amine compounds was achieved using p-toluenesulfonic acid in the solid state condition at 25-45 ˚c. the salient features of this methodology are shorter reaction times, cheap processing, high yields of product and easy availability of the catalyst. ...

limn2o4 spinel cathode materials have been successfully synthesized by solid-state reaction. surface of these particles were modified by nanostructured lifepo4 via sol gel dip coating method. synthesized products were characterized by thermally analyzed by thermogravimetric and differential thermal analysis(tg/dta), x-ray diffraction (xrd), scanning electron microscopy (sem), and energy dispers...

optimization of the fermentation medium for maximum alkaline protease production was carried out. fifteen positive isolates were examined for their extent of alkaline protease production. the most potent producer was identified as bacillus sp. the solid substrate screening showed that the combination of wheat straw and bean husk was the best one. the initial screening by using plackett–burman’s...

copper oxide nanostructures have been successfully synthesized via one-step solid-state thermolysis of two metal-organic frameworks, [cu3(btc)2] (1) and [cu(tpa).(dmf)] (2), (btc = benzene-1,3,5-tricarboxylate, tpa = therephtalic acid = 1,4-benzendicarboxylic acid and dmf = dimethyl formamide) under air atmosphere at 400,  500, and 600°c. it has also been found that the reaction temperature pla...

In studying solid state electronic devices we are interested primarily in the electrical behavior of solids. However, we shall see in later chapters that the transport of charge through a metal or a semiconductor depends not only on the properties of the electron but also on the arrangement of atoms in the solid. In the first chapter we shall discuss some of the physical properties of semicondu...

The in vitro experimental investigations provide an excellent approach to understand complex blood flow phenomena involved at a microscopic level. This paper emphasizes an emerging experimental technique capable to quantify the flow patterns inside microchannels with high spatial and temporal resolution. This technique, known as confocal micro-PIV, consists of a spinning disk confocal microscop...

Plasmonic hot-electron devices are attractive candidates for light-energy harvesting and photodetection applications. For solid state devices, the most compact and straightforward architecture is the metal-semiconductor Schottky junction. However convenient, this structure introduces limitations such as the elevated dark current associated to thermionic emission, or constraints for device desig...

Electrode-embedded nanopore is considered as a promising device structure for label-free single-molecule sequencing, the principle of which is based on nucleotide identification via transverse electron tunnelling current flowing through a DNA translocating through the pore. Yet, fabrication of a molecular-scale electrode-nanopore detector has been a formidable task that requires atomic-level al...
