out providing a magnificent enhancement of the temporal resolution in electron microscopy. Another optical laser pulse can be utilized to trigger the ultrafast dynamics of matter which can be envisaged by gated-electrons in different modes i.e. diffraction, electron…

3.4. Ternary systems MgO-SF-QF (MgO-SiO2-Quartz fillers) 3.4.1. Effect of crushed quartz filler on water reduction The idea of adding crushed quartz filler to M-S-H binder is inherited from replacement of Portland cement with quartz filler to improve the rheology of cement paste [25] due to the less water absorption and smooth texture of finely ground quartz particles. Fig. 9 described water reduction effect as adding crushed quartz filler (QF) to MgO-SiO2 binary system to maintain a fixed flow…

Ternary systems MgO-SF-QF 3.4.1. Effect of crushed quartz filler on water reduction The idea of adding crushed quartz filler to M-S-H binder is derived from a study of Portland cement replacement with quartz filler to improve the rheology [25] due to the less water absorption and smooth texture of finely ground quartz particles. Fig. 9, 10 described water reduction effect of adding crushed quartz filler to maintain a fixed flow of MgO-SF-QF ternary systems (Series 3, 4, 5). The replacement of…

Light synthesis principles The basic idea of light waveform synthesis can be described as follows: First, the spectrum of a light waveform is decomposed into its constituent spectral components by a disperser, then, adequate modulators acting on each of this spectral components individually modifies the relative phase (or delay), the amplitude and polarization of these components before they are coherently superimposed again by a combiner to create a desired tailored waveform (Figure 2a)41.…

The visible pulse (gating pulse) enters the microscope, and together with the ultrafast electron pulses illuminate the nanostructure specimen (gold nanoparticle). The visible laser pulse kept at low power (~1.8 mJ/cm2) to avoid saturation. At the spatiotemporal overlapping, the coupling between the visible and electron pulses takes place. The signature of this coupling can be revealed by measuring the electron energy spectrum using the electron energy spectrometer attached to the microscope. The…

“Architecture describe as frozen music, landscape as thawed music”, this is my favorite sentence from the book . The author of the book--John Powell was using the eyes of artist to look our world. Landscape is described as a dynamic and flowing thing. It has more similarity with music. In other words, the way we feel landscape is quite similar with how we feel music. We could get different feeling, receive different experiences in different sections and time of a music, so does in landscape. It…

amorphous glass substrates for various precursor solution volumes from 5 ml to 25 ml in steps of 5 ml by nebulized spray pyrolysis method. The Hexagonal structure of the films with preferential orientation along (001) plane was confirmed by X-ray diffraction studies. The crystallite size of SnS2 thin films was found to increase with the increase in precursor solution volume up to 20 ml and then it decreased at the precursor solution volume of 25 ml. The scanning electron microscope established…

ABSTRACT The reactivity of acid base cements forming hydroxyapatite (HA) such as, β-tricalcium phosphate (β-TCP) and dicalcium phosphate dehydrate (DCPD). Amorphous calcium phosphates, prepared by precipitation from supersaturated solutions, can also react to form apatitic cements since they are thermodynamic unstable with respect to HA and have a setting reaction more independent of particle size. Calcium phosphate cement containing an antibiotic can be used for filling bone defects and to…

the Earth. This has been observed by telescopes since the middle of the XVII century. IV. Space Age The first spacecraft that reached the Moon were the Luna 1, 2 and 3 of the former Soviet Union, in 1959. Of these, the Luna 3 orbited the Moon, took photographs of the dark side, which is not visible from Earth, and then scanned and transmitted those images. In the decade that followed, 19 other missions had as its goal the Moon. In 1970 a Soviet lunar vehicle landed and was able to return with a…

to 5D0 level of Eu3+ from Tb3+: SA. Conclusion Bulk single crystals of semi organic Tb3+ co activated sulfamic acid single crystals are grown in unidirectional (100) from aqueous solution by a slow evaporation technique. Single crystal X-ray diffraction studies confirm that the grown crystal belongs to orthorhombic crystal system with space group Pbca. The grown crystals of single crystal XRD and…
