Variation of two and three photon upconversion band intensities in LNO:Er1%–Yb7.5% phosphor with temperature.
Austenitic stainless steels that exhibit good corrosion resistance have recently found increasing applications in industry and transportation. This article addresses the influence of cold rolling deformation on pitting AISI 301LN 316L steels. The results indicate content martensite increases as reduction also increases. current work combined different techniques such optical microscopy scanning electron (SEM) with energy dispersive X-ray spectroscopy (EDS) analyses. Corrosion tests were...
In this paper Mössbauer, Raman and dielectric spectroscopy studies of BiFeO3 (BFO) ceramic matrix with 3 or 10 wt% Bi2O3 PbO added, obtained through a new procedure based on the solid-state method, are presented. Mössbauer shows presence single magnetically ordered phase hyperfine magnetic field 50 T. spectra BFO over frequency range 100–900 cm−1 have been investigated, at room temperature, under excitation 632.8 nm wavelength in order to evaluate effect additives structure matrix. Detailed...
Nowadays, the development of sustainable high-performance functional nanomaterials is in spotlight. In this work, we report preparation a new generation flexible and high electroconductive nanopapers based on nanofibrillated cellulose (NFC) copper nanowires (CuNWs). Homogeneous red brick color (thickness 30.2-36.4 μm) were obtained by mixing different amounts NFC aqueous suspensions CuNWs (1, 5, 10, 20, 50 wt %), followed vacuum filtration drying. scanning electron microscopy (SEM)...
This study reports the synthesis of polyurethane–lignin copolymer blended with carbon multilayer nanotubes to be used in all-solid-state potentiometric chemical sensors. Known applicability lignin-based polyurethanes doped for sensing was extended eucalyptus LignoBoost® kraft lignin containing increased amounts polyphenolic groups from concomitant tannins that were expected impart specificity and sensitivity material. Synthesized polymers characterized using FT-MIR spectroscopy, electrical...
