Graphitic carbon nitride (g-C3N4) microspheres (CNMS) were fabricated via a solvothermal method by using supramolecular complexes of dicyandiamide and cyanuric chloride as precursors. The effect of solvothermal temperature on the morphology, band structure, and activity was systematically investigated. Structural characterization results indicate that the samples prepared at 180 °C (CNMS-180) and ...... hiện toàn bộ
Effects of hydroxyls on the structural and room temperature ferromagnetic properties of Co doped SnO2 nanoparticlesApplied Physics A Solids and Surfaces - Tập 97 - Trang 211-215 - 2009

Co doped SnO2 nanoparticles have been prepared via a wet chemical method with different precipitation processes. The structure and morphology of Co doped SnO2 nanoparticles demonstrate that the nanoparticles are in a rutile single phase and uniform, respectively. X-ray photoelectron spectroscopy shows that the Co dopants are in 2+ oxidation valence state and doped ∼2 atm% in SnO2 nanoparticles. Mo...... hiện toàn bộ

Paper is one of the most important materials in cultural heritage given its extensive use as the data carrier for religious, artistic and scientific records. For both aesthetic and conservation reasons, cleaning of these materials is often needed. Current paper cleaning methods using conventional means are not always sufficient, e.g. for the local cleaning of paper in the vicinity of sensitive med...... hiện toàn bộ
Dirt reference standard for surface cleanliness measurementsApplied Physics A Solids and Surfaces - Tập 122 - Trang 1-5 - 2016
D. J. O. Orzi, G. M. Bilmes
Thin films based on polymer poly(isobutyl methacrylate) (PIBMA), doped with carbon black particles deposited on steel plate substrates are proposed as dirt reference standards for cleanliness accreditation methods, particularly for instruments based on laser ablation. The films were made with the spin-coating method, obtaining layers with thickness between 4 and 17 μm. Carbon black particles with ...... hiện toàn bộ
Giant optical nonlinearity of silver-doped silicon thin film at low power input: laser-triggered cluster resonanceApplied Physics A Solids and Surfaces - Tập 104 - Trang 1031-1037 - 2011
Jingsong Wei, Jing Liu, Mufei Xiao
Silver-doped silicon thin films were deposited on glass substrate in a co-sputtering procedure. Silver nanoparticles were segregatedly distributed. The nonlinear properties were extracted by z-scan measurements at low laser input power. For about 50% silver density, the nonlinear absorption and refraction coefficients peaked, respectively, at −8.086×10−2 m/W and 1.47×10−9 m2/W, which, with respect...... hiện toàn bộ
A novel methodology to suppress ambipolarity and improve the electronic characteristics of polarity-based electrically doped tunnel FETApplied Physics A Solids and Surfaces - Tập 125 - Trang 1-7 - 2019

In this letter, we have explored the effect of metal strip (MS) approach on electrically doped tunnel field effect transistor (ED-TFET) in the presence of hetero-material (HM) and named the proposed device as hetero-material metal strip electrically doped tunnel FET (HM–MS–ED-TFET). Intention of our work is to suppress the ambipolar current and improve the device electronic characteristics; for th...... hiện toàn bộ
