We demonstrate fiber few-mode interferometers based on a self-assembly surface corrugated grating using charged nano-particles. Initially, an abrupt taper (AT) was first created micro flame. The AT then further outwardly stretched to make elongated uniformed until the tapered diameter achieved micron scale. high order core modes (HOCMs) were excited at and optical path difference (OPD) among en...

Complexity and heterogeneity are common denominators of the many molecular events taking place inside the cell. Single-molecule techniques are important tools to quantify the actions of biomolecules. Heterogeneous interactions between multiple proteins, however, are difficult to study with these technologies. One solution is to integrate optical trapping with micro-fluidics and single-molecule ...

Single-molecule fluorescence microscopy enables non-invasive, high-sensitivity, high-resolution imaging, and this direct, quantitative method has recently been extended to understanding organization, dynamics and cooperativity of macromolecules in prokaryotes. In this issue of Molecular Microbiology, Bakshi et al. (2012) examine fluorescently labelled ribosomes and RNA polymerase (RNAP) in live...

The time evolution of the quantum entropy in a coherently driven threelevel quantum dot (QD) molecule is investigated. The entanglement of quantum dot molecule and its spontaneous emission field is coherently controlled by the gat voltage and the intensity of applied field. It is shown that the degree of entanglement between a three-level quantum dot molecule and its spontaneous emission fields...

waterwheels are the oldest types of hydraulic machines. these turbines are of relatively simple design, large diameter, low rotational speed and high torques. but applying them as micro hydros of high speed and small diameter is yet to be explored. a micro hydro waterwheel of one meter diameter was designed and manufactured at the iranian  esearc†h organization for science and technology (irost...

The elucidation of complex biological processes often requires monitoring the dynamics and spatial organization multiple distinct proteins organized on sub-micron scale. This length scale is well below diffraction limit light, as such not accessible by classical optical techniques. Further, high molecular concentrations found in living cells, typically micro- to mili-molar range, preclude singl...

The article is devoted to the development and synthesis of a new drug for use in animal husbandry veterinary medicine as an immunostimulatory adaptogenic agent. basis combination magnesium, phosphorus, casein cow's milk.
 Given important scientific practical importance innovative drugs that would have pronounced properties, aim our research develop method obtaining with original compositio...

The synthesis and magnetic properties of the compound [Mn(22)O(6)(OMe)(14)(O(2)CMe)(16)(tmp)(8)(HIm)(2)] 1 are reported. Complex 1 was prepared by treatment of [Mn(3)O(MeCO(2))(6)(HIm)(3)](MeCO(2)) (HIm = imidazole) with 1,1,1-tris(hydroxymethyl)propane (H(3)tmp) in MeOH. Complex 1.2MeOH crystallizes in the orthorhombic space group Pbca. The molecule consists of a metallic core of 2 Mn(IV), 18 ...

The lignin aerogels that are both high porosity and compressibility would have promising implications for bioengineering field to sound-adsorption and damping materials; however, creating this aerogel had a challenge to adhesive lignin. Here we reported cellulose as green adhesion agent to synthesize the aerogels with strong mechanical performance. Our approach-straightforwardly dissolved in io...
