Fully energy-filtered X-ray photoelectron emission microscopy is used to analyze the spatial distribution of the silicon sub-oxide structure at the SiO2/Si interface as a function of underlying doping pattern. Using a spectroscopic pixel-by-pixel curve fitting analysis, we obtain the sub-oxide binding energy and inten…
Aggregation-induced emission-active 9,10-bis[(N-alkylcarbazol-3-yl)vinyl]anthracenes (ACZn) with different length of N-alkyl chains have been designed and synthesized to systematically investigate the effect of chain length on the solid-state fluorescence properties. The results show that these materials exhibit not o…
A new form of graphene-coated silica (GCS) has been prepared by mixing exfoliated graphene oxide with acid-treated silica and reducing it with hydrazine hydrate so that it coats the silica particles. This method is simple, convenient, and robust. The GCS composite particles have been characterized using optical photog…
Abstract The subject of tribology encompasses the friction, wear and lubrication of mechanical components such as bearings and gears. Tribological practices are aimed at ensuring that such components operate with high efficiency (low friction) and achieve long lives. On spacecraft mechanisms the route to achieving the…
NO removal by CO model reaction was investigated over a series of ceria-containing solid solutions, prepared by an inverse co-precipitation method, to explore the relationship between the physicochemical properties and catalytic performances of these catalysts. The synthesized samples were studied in detail by means o…
Stretchable electronics are emerging as a new technological advancement, since they can be reversibly stretched while maintaining functionality. To power stretchable electronics, rechargeable and stretchable energy storage devices become a necessity. Here, we demonstrate a facile and scalable fabrication of full stret…
We report electrical conductance and thermopower measurements on InAs nanowires synthesized by chemical vapor deposition. Gate modulation of the thermopower of individual InAs nanowires with a diameter around 20 nm is obtained over T = 40-300 K. At low temperatures (T < ∼100 K), oscillations in the thermopower and pow…
NiO nanoparticles with sizes of 3.5–12.4 nm were grown by thermal decomposing of nickel acetate at different temperatures in NaCl and Li 2 CO 3 alkalisalts. The properties of the nanoparticles were characterized by X-ray diffraction spectrometer, transmission electron microscope, absorption spectrometer, micro-Raman m…
The loss of coherence is one of the main obstacles for the implementation of quantum information processing. The efficiency of dynamical decoupling schemes, which have been introduced to address this problem, is limited itself by the fluctuations in the driving fields which will themselves introduce noise. We address…
Ternary-component NiCoAl-layered double hydroxide nanosheets (NiCoAl-LDH) and multiwall carbon nanotube (MWCNT) nanohybrids (NiCoAl-LDH–MWCNT) have been successfully fabricated by a facile yet simple urea precipitation method. The MWCNTs are well incorporated into the network of NiCoAl-LDH nanosheets to form homogeneo…
We report the design of all-solid-state asymmetric supercapacitors based on free-standing carbon nanotube/graphene (CNTG) and Mn(3)O(4) nanoparticles/graphene (MG) paper electrodes with a polymer gel electrolyte of potassium polyacrylate/KCl. The composite paper electrodes with carbon nanotubes or Mn(3)O(4) nanopartic…
This article summarizes the main achievements and challenges in the field of the aqueous synthesis of semiconductor quantum dots in colloidal solutions. Developments in the last two decades demonstrate the great potential of this approach to synthesize nanocrystalline materials with superior properties such as strong…
In the pursuit of optimized magnetic nanostructures for diagnostic and therapeutic applications, the role of nanoparticle architecture has been poorly investigated. In this study, we demonstrate that the internal collective organization of multi-core iron oxide nanoparticles can modulate their magnetic properties in s…
Polymer chemists, through advances in controlled polymerization techniques and reliable post-functionalization methods, now have the tools to create materials of almost infinite variety and architecture. Many relevant challenges in materials science, however, require not only functional polymers but also on-demand acc…
Here we report on a novel substrate, nanopaper, made of cellulose nanofibrils, an earth abundant material. Compared with regular paper substrates, nanopaper shows superior optical properties. We have carried out the first study on the optical properties of nanopaper substrates. Since the size of the nanofibrils is muc…
High intensity ultrasound can be used for the production of novel materials and provides an unusual route to known materials without bulk high temperatures, high pressures, or long reaction times. Several phenomena are responsible for sonochemistry and specifically the production or modification of nanomaterials durin…
The effect of epoxidation and surface modification by acrylamide grafting on backing-required properties of peroxide prevulcanized natural rubber (PPNR)-based films was investigated. Backing-required properties including oxygen transmission rate (OTR), water vapor transmission rate (WVTR) and Young’s modulus were dete…
The thermodynamics of ferroelectric phase transitions is an important constituent part of the phenomenological theories of them, as well as the interface dynamics of them. In particular, if we confine the thermodynamics to the equilibrium range, we can say that the LandauDevonshire theory is a milestone in the process…
Abstract The defect accumulation in helium‐implanted 4H–SiC was studied in a large range of temperatures through the elastic strain build‐up determined by using X‐ray diffraction measurements. The interstitial type defects formation and accumulation result in the strain build‐up that was modelled with a multi‐step dam…
We report on a broadband polarization splitting phenomenon in an aluminum grating with its period much smaller than the wavelength of incident light. Under oblique incidence, grating is highly transparent for one polarization, but it is opaque and reflects the orthogonal polarization. By using the Fourier modal method…
