Distinguishing of individual constituents in complex materials is one of the primary tasks of microscopy that is achieved by visualization of specific shapes and features of components. Electron microscopy and atomic force microscopy (AFM) [1] extend visualization of objects down to the atomic scale thus enhancing compositional imaging. The situation becomes less trivial when the constituents l...
This article describes a novel one-step method to prepare cellulose nanocrystals (CNCs) from bleached bagasse pulp via ammonium persulfate (APS) oxidation. The obtained persulfate oxidation cellulose nanocrystals (POCNs) were characterized for their microstructure, crystal properties, and chemical composition. The POCNs were successfully prepared with a total yield of 44.6%. Transmission electr...
GaAs nanowires were heated locally under ambient air conditions by a focused laser beam which led to oxidation and formation of crystalline arsenic on the nanowire surface. Atomic force microscopy, photoluminescence and Raman spectroscopy experiments were performed on the same single GaAs nanowires in order to correlate their structural and optical properties. We show that the local changes of ...
The past decade has witnessed the tremendous scientific and technological potential of nanoscale flexoelectricity in solids. flexoelectric effect describes universal generation electric polarization response to strain gradients could be inversely enhanced at reduced dimensions. Based on this unique scaling effect, shown exciting physical phenomena, promising novel electronic, electromechanical,...
