In this context, biopolymer-based delivery systems present themselves as a promising strategy encapsulating bioactive compounds, improving their absorption, stability, functionality. This study provides an exploration synthesis, characterization, postharvest...
The use of nanocarriers (NCs), i.e., nanomaterials capable encapsulating drugs and releasing them selectively, is an emerging field in agriculture. In this study, the synthesis, characterization, vitro vivo testing biodegradable NCs loaded with natural bioactive products was investigated for control certain phytopathogens responsible wood degradation. particular, based on methacrylated lignin chitosan oligomers, extracts from Rubia tinctorum, Silybum marianum, Equisetum arvense, Urtica...
Solution-processed near-infrared organic light-emitting diodes (NIR-OLEDs) with structure glass/indium–tin oxide/poly(3,4-ethylenedioxythiophene)-poly(styrene sulfonate)/Er-complex/Ca/Al based on a novel Er(III) complex, [Er(tfnb)3(bipy)] (Htfnb = 4,4,4-trifluoro-1-(2-naphthyl)-1,3-butanedione and bipy 2,2′-bipyridine) have been manufactured their properties studied. A complete quenching of the ligand visible emission is shown, only sensitized 1.5 μm electroluminesce from results. From...
Three novel ternary Er3+ complexes emitting in the C band transmission window for fiber optic communications have been synthesised and their structures elucidated by single crystal X-ray diffraction. The fluorinated β-diketonate ligand, 1,1,1-trifluoro-5,5-dimethyl-2,4-hexanedione, combines a good absorption cross-section ultraviolet region with reduction of non-radiative quenching emission, while rigidity bulkiness three different N,N-donors (2,2′-bipyridine, bathophenanthroline...
SUMMARY Objective: The aim was to evaluate the color longevity after nine months of in-office bleaching with gel (6% hydrogen peroxide), compare this a control concentration 35% in split-mouth study model, and assess dental confidence psychosocial impact on patients. Methods Materials: Twenty-seven patients were assessed at nine-month recall. procedure 6% or peroxide performed randomly upper hemi-arch each patient. measured baseline one week, month, procedure, using Vita Easyshade...
This study reports evidence on the feasibility of a classification natural resins by ATR-FTIR spectroscopy based specific absorbance band positions. A set twelve selected were used to assess position variability and this vibrational data was put in relationship with chemical composition resins. As result, into following four main families is proposed: 1) those correlated communic acids (sandarac, black copal, pine pitch amber); 2) associated abietic acid (rosin mastic); 3) ketone groups...
Despite extensive research on the chemical composition of elderberries and their numerous uses in pharmaceutical, beverage, food production, there is still a lack knowledge about Sambucus nigra leaves flowers' antimicrobial activity against plant pathogens. In this study, phytoconstituents aqueous ammonia extracts were first characterized by infrared spectroscopy gas chromatography-mass spectrometry. The major phytocompounds identified flower extract octyl 2-methylpropanoate;...
French tamarisk, Tamarix gallica L. (family Tamaricaceae) is a deciduous tree that, like other halophytes, grows in wide variety of saline habitats thanks to its powerful phenolics-based antioxidant system. Given that properties are usually linked the presence compounds with antifungal properties, work presented herein antimicrobial activity T. bark extract was investigated against four phytopathogenic species genus Fusarium. According results gas chromatography–mass spectroscopy,...
Santolina chamaecyparissus L. (cotton-lavender) is receiving increasing attention due to its potential for modern medicine and considered both a functional food nutraceutical. In this work, the phytochemical profile of flower hydromethanolic extract was investigated by gas chromatography-mass spectrometry, applications as biorational crop protection were explored against Neocosmospora spp., in vitro planta. The profiling analysis identified several terpene groups. Among sesquiterpenoids,...
Erbium complexes featuring β-diketonate ligand 2,4-hexanedione (Hh) and N,N-donor-ligands 2,2′-bipyridine (bipy), 5-nitro-1,10-phenanthroline (5NO2phen) bathophenanthroline (bath) have been synthesized. The structures of the ternary [Er(h)3(bipy)], [Er(h)3(5NO2phen)] [Er(h)3(bath)] determined by single crystal X-ray diffraction. Excitation in ultraviolet region (337 nm) led to near infrared (NIR) luminescence at 1532 nm characteristic trivalent erbium ion three compounds, with an improved...
Most people who make the transition to renal replacement therapy (RRT) are treated with a fixed dose thrice-weekly hemodialysis réegimen, without considering their residual kidney function (RKF). Recent papers inform us that incremental is associated preservation of RKF, whenever compared conventional hemodialysis. The objective present controlled randomized trial (RCT) determine if start HD one sessions per week (1-Wk/HD), it better patient survival and other safety parameters. IHDIP...
In the work presented herein, we analyze efficacy of three basic substances that comply with European Regulation (EC) No 1107/2009, namely chitosan, horsetail (Equisetum arvense L.) and nettle (Urtica dioica L.), for control grapevine trunk diseases (GTDs) in organic farming. The E. U. aqueous extracts, prepared according to SANCO/12386/2013 SANTE/11809/2016, have been studied by gas chromatography–mass spectrometry (GC-MS), identifying their main active constituents. substances, either...
