Direct mapping of the lithium spatial distribution and chemical state provides critical information on structure-correlated transport in electrode materials for batteries. Nevertheless, probing lithium, lightest solid element periodic table, poses an extreme challenge with traditional X-ray or electron scattering techniques due to its weak power vulnerability radiation damage. Here, we report nanoscale maps electrochemically lithiated graphite using energy loss spectroscopy transmission...
The static and dynamic properties of \ensuremath{\beta}-Sn, SnO, ${\mathrm{SnO}}_{2}$ are studied using the full-potential linear-muffin-tin-orbital method within local-density approximation (LDA). Equilibrium lattice parameters bulk moduli (including pressure variations) in excellent agreement with experimental values. cohesive energies calculated too large, accordance usual overbinding found LDA. Optical \ensuremath{\Gamma}-point phonon frequencies obtained frozen approach. For those modes...
Carbon nanostructures have received much attention for a wide range of applications. This paper reviews the historical role plasmas in gas-phase synthesis carbon and present plasma technologies industrial production purposes. It enumerates advantages disadvantages with respect to concurrent commonly employed nowadays. Finally, some produced our laboratory will serve as examples processes potential.
Abstract This paper demonstrates how the integration of multi-physics downhole imaging with machine learning techniques provides a step-change in perforation erosion analysis. We present novel approach that improves measurement accuracy, consistency, and turnaround time. reveal this benefits fields completion design optimisation hydraulic fracturing, enables gains productivity reduction cost development unconventional wells. Downhole data is acquired from an integrated array video phased...
The presence of silver nanoparticles (AgNPs) in water bodies has emerged as a new environmental concern and the efficient separation these remains critical challenge. Here, we developed novel magnetic nanoflocculants for recovery AgNPs from water. Alternating layers biopolymers, particular, chitosan, alginate, polymeric bio-based soluble substances (BBS) derived urban waste, were coated on via layer-by-layer technique to prepare reusable (MNFs). MNFs obtained characterized with diverse...
We have used electron energy-loss spectroscopy to search for differences in the near-edge structure of SnO, ${\text{SnO}}_{2}$, and an intermediate oxide, with a view distinguishing them unambigously. found that oxygen $K$ edge exhibits clear can be fingerprinting each phase. The appears at same position phase whereas chemical shift Sn ${M}_{4,5}$ about $3.5\phantom{\rule{0.3em}{0ex}}\text{eV}$ was observed between phases $2+$ $4+$ oxidation states. Both observations distinguish three...
The use of MgB2 in superconducting applications still awaits the development a MgB2-based material where current-carrying performance and critical magnetic field are optimized simultaneously. We achieved this by doping with double-wall carbon nanotubes (DWCNT) as source polycrystalline samples. optimum nominal DWCNT content for increasing current density, Jc, is range 2.5–10 at.% depending on temperature. Record values upper field, Hc2(4 K) = 41.9 T (with extrapolated Hc2(0)≈44.4 T), reached...
The realization of materials at the nanometer scale creates new challenges for quantitative characterization and modeling as many physical chemical properties nanoscale are highly size shape-dependent. In particular, accurate nanometrological noble metal nanoparticles (NPs) is crucial understanding their optical response that determined by collective excitation conduction electrons, known localized surface plasmons. Its manipulation gives place to a variety applications in ultrasensitive...
Lattice dynamics of tin monoxide was investigated by M\"ossbauer spectroscopy in the range 16--294 K. From temperature dependence absolute recoil-free fraction, f(T), second moment phonon spectrum and anharmonic constant \ensuremath{\varepsilon}(-2) were determined. These results suggest that dominant contribution arises from cubic term vibrational phonon-phonon coupling Hamiltonian. The recoilless fraction determined at room linewidth method found to be f(295 K)=0.${12}_{1}$. No phase...
