Individual nanoparticles of silicon and titanium having diameters in the range $40--140\phantom{\rule{0.3em}{0ex}}\mathrm{nm}$ have been repeatedly compressed by a nanoindenter. Even at low loads, small tip-particle particle-substrate contacts generate extreme pressures within confined particle, influencing its stiffness fracture toughness. The effect these high on measured modulus is taken into account invoking Murnaghan equation-of-state-based analysis. Fracture toughness particles found...
Yogasana, often simply referred to as “asana”, is a Sanskrit term that encompasses the physical postures or poses practiced in yoga. Traditionally, there are almost 90 classical Yogasanas, each with its unique benefits and variations. It's very important identify of asana. Classifications Yogasana can have significant impact on practice promotion yoga, making it more accessible, educational, safe for people all skill levels. In this research work, we automatically identified different...
This paper reports an effective approach for fabricating a thermo-responsive gel polymer based on dithioacetylation of quinoline-2,4-dicarbaldehyde and used as sensor detecting metal ions. The synthesis was confirmed using NMR spectroscopy. effect varying temperatures solvents investigated the formation polymeric gel, mechanism explained. synthesized to detect Hg2+ ions in various samples. showed turn-on-fluorescence sensitivity ion with excellent photoluminescence properties, fluorescence...
Small volume deformation can produce two types of plastic instability events. The first involves dislocation nucleation as a by event and occurs in nanoparticles or bulk single crystals deformed atomic force microscopy small nanoindenter forces. For the second event, this larger scale nanocontacts into their films wherein multiple dislocations cooperate to form large displacement excursion load drop. With work, surface stored elastic energy, one account for energy expended both This leads an...
Zero dimensional graphene quantum dots (GQDs) exhibit interesting physical and chemical properties due to the edge effect confinement. As number of carbon atoms in is more than on basal plane, GQDs are reactive. Room temperature XRD pattern confirms formation GQDs. UV-Visible spectra confirm that show optical absorption visible region. The emission peaks photoluminescence red shifted with increase excitation wavelength. Dynamic light scattering (DLS) analysis shows average size particles...
ZnTe semiconductor nanoparticles have been prepared by soft chemical route using mercaptoethanol as capping agent to arrest the agglomeration. The structural investigations performed X-ray diffraction technique show that samples cubic structure. Average crystallite sizes of nanomaterial are estimated Debye–Scherrer’s equation. particle size synthesized material is transmission electron microscope (TEM). UV-visible absorption spectra gives idea band gap sample Tauc plot. Raman spectroscopy...
