Fluorescence lifetime imaging of lignin autofluorescence in normal and compression wood
(Wiley-Blackwell, Hoboken, 2013)
Wood cell walls fluoresce as a result of UV and visible light excitation due to the presence of lignin. Fluorescence spectroscopy has revealed characteristic spectral differences in various wood types, notably normal and ...
Lead-free BaBi4Ti4O15 ceramics: Effect of synthesis methods on phase formation and electrical properties
(Elsevier Sci Ltd, Oxford, 2015)
The processing of ferroelectric BaBi4Ti4O15 (BBT) ceramics from powders prepared by conventional solid state reaction (SSR) and mechanochemical activation (MA) has been investigated. It was shown that MA synthesis reduces ...
Quercetin 7-O-glucoside suppresses nitrite-induced formation of dinitrosocatechins and their quinones in catechin/nitrite systems under stomach simulating conditions
(Royal Soc Chemistry, Cambridge, 2015)
Foods of plant origin contain flavonoids. In the adzuki bean, (+)-catechin, quercetin 3-O-rutinoside (rutin), and quercetin 7-O-beta-D-glucopyranoside (Q7G) are the major flavonoids. During mastication of foods prepared ...
Structural and electrical properties of sintered Fe2O3/TiO2 nanopowder mixtures
(Elsevier Sci Ltd, Oxford, 2014)
Starting nanopowders of TiO2 (anatase 99.7%) and alpha-Fe2O3 (hematite) were mixed in the weight ratios 60:40 and 40:60. Green samples were sintered in the temperature range 750-1250 degrees C in air. Structural, morphological ...
Fingerprint imaging using N-doped carbon dots
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
Carbon Dots (CDs) were obtained using a hydrothermal method and used for the detection of finger-prints through fluorescent imaging. Synthesized CDs exhibited a brightness emission at 495 nm, which was related to their ...
Tyramine-modified pectins via periodate oxidation for soybean hull peroxidase induced hydrogel formation and immobilization
(Springer, New York, 2017)
Pectin was modified by oxidation with sodium periodate at molar ratios of 2.5, 5, 10, 15 and 20 mol% and reductive amination with tyramine and sodium cyanoborohydride afterwards. Concentration of tyramine groups within ...
Silicon Improves the Production of High Antioxidant or Structural Phenolic Compounds in Barley Cultivars under Aluminum Stress
(MDPI, Basel, 2019)
Aluminum (Al) toxicity is one of the main growth and yield limiting factors for barley grown on acid soils. Silicon (Si) ameliorates Al toxicity as well as it promotes the phenolic compounds production that have antioxidant ...
Lignin model compound in alginate hydrogel: a strong antimicrobial agent with high potential in wound treatment
(Elsevier, Amsterdam, 2016)
Nowadays bacterial resistance to known antibiotics is a serious health problem. In order to achieve more efficient treatment, lately there is an effort to find new substances, such as certain biomaterials, that are non-toxic ...
Analysis of static bending-induced compression wood formation in juvenile Picea omorika (Pancic) Purkyne
(Springer Heidelberg, Heidelberg, 2015)
Young P. omorika trees subjected to static bending showed a severe compression wood response as characterized by fluorescence spectroscopy/microscopy, which decreased in severity with height correlated with a decrease in ...
Component analysis of fluorescence spectra of thiol DAB dendrimer/ZnSe-PEA nanoparticles
(Elsevier Science Bv, Amsterdam, 2013)
The fluorescence spectroscopy technique is an accurate method and has great utility in the interpretation of complex systems based on several emission bands. An interpretation of the system requires determination of the ...
