The pulse train effects on femtosecond laser material processing are investigated from the viewpoint of electron dynamics on dielectrics with fused silica as a case study and metals with Al as a case study in air and water. During femtosecond laser (800 nm, 35 fs) pulse train (double pulses per train) processing of fused silica, a non-monotonic relationship between ablation size and pulse separati...... hiện toàn bộ
Morphology and band structure regulation of graphitic carbon nitride microspheres by solvothermal temperature to boost photocatalytic activityApplied Physics A Solids and Surfaces - Tập 124 - Trang 1-11 - 2018

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
