Fractionation of softwood and hardwood LignoBoost kraft lignins, using sequential extraction with organic solvents increasing hydrogen-bonding ability (dichloromethane, n-propanol, methanol), was carried out. Using SEC, analytical pyrolysis, FTIR UV/VIS spectroscopy, chemical methods, four fractions were obtained characterized in terms their yield, composition, functionality, lignin structural features, antioxidant properties. In tests free radicals (ABTS●+, DPPH●, O2●-) the ORAC (oxygen...
Abstract Molecularly imprinted polymers are important tools for the design of sensors and other molecular recognition based analytical systems. In this paper development a photoelectrochemical sensor selective bisphenol determination is reported. The on glass/ZnO/MIP‐Ppy structure consisting glass modified by ZnO layer (glass/ZnO), which functionalized molecularly conducting polymer polypyrrole (MIP‐Ppy). sensitivity to in range 0.7–12.5 µ m . Selectivity tests bisphenolic compounds...
For high-performance lithium-ion batteries (LIBs), Bi 2 Se 3 /MXene/SWCNT heterostructures emerge as a possible anode choice.
One way to improve characteristics of oxide coatings prepared by plasma electrolytic oxidation (PEO) method in suspensions lies variation solid particle properties. In this study, the effect crystallinity on different physicochemical properties and bioactivity Ti Ti6Al4V substrates was studied, repeatability resulting assessed depending selected substrates. PEO performed direct current mode at a voltage 350 V electrolytes containing 0.1 M KH2PO4 100 g.L-1 stoichiometric crystalline...
Honey is widely used in traditional medicine and modern wound healing biomaterial research as a broad-spectrum antimicrobial, anti-inflammatory antioxidant agent. The study's objectives were to evaluate the antibacterial activity polyphenolic profiles of 40 monofloral honey samples collected from beekeepers territory Latvia. antimicrobial antifungal Latvian compared with commercial Manuka analogue sugar solutions-carbohydrate mixture tested against Escherichia coli, Pseudomonas aeruginosa,...
The economic significance of honey production is crucial; therefore, modern and efficient methods authentication are needed. During the last decade, various data processing a combination several instrumental have been increasingly used in food analysis. In this study, chemical composition monofloral buckwheat (Fagopyrum esculentum), clover (Trifolium repens), heather (Calluna vulgaris), linden (Tilia cordata), rapeseed (Brassica napus), willow (Salix cinerea), polyfloral samples Latvian...
Various pretreatment methods, often employed in wood biorefineries, aim to disrupt the architecture, thereby enhancing efficiency of hemicellulose extraction for increasing production bio-ethanol, bio-gas, and bio-oil, as well improving pulping process. Pretreatment process has advantages such enhanced yield biorefined products reducing chemicals energy consumption. This study examined effect an alkaline hydrolysis birch sawdust on chemical composition, aggregation ability, surface activity...
Both the binder and solid–electrolyte interface play an important role in improving cycling stability of electrodes for Na-ion batteries. In this study, a novel tetrabutylammonium (TBA) alginate is used to prepare Na0.67MnO2 electrode sodium-ion batteries with improved electrochemical performance. The ageing characterized. TBA alginate-based are compared polyvinylidene fluoride- (PVDF) Na show favorable performance, gravimetric capacity values up 164 mAh/g, which 6% higher than measured...
