The application of ionic liquids (ILs) has grown enormously, from their use as simple solvents, catalysts, media in separation science, or electrolytes to that task-specific, tunable molecular machines with appropriate properties. A thorough understanding these properties and structure-property relationships is needed fully exploit potential, open new directions IL-based research and, finally, properly implement the applications. In this work, we investigated structure-properties a series...
Magnetic resonance imaging (MRI) was used to study temporal and spatial water uptake distribution in germinating lupine ( Lupinus luteus L.) seeds. During 24 h of imbibition, unevenly distributed within the seed some anatomical parts were more hydrated than others. Water entered through hilum micropyle. The embryonic axis first show hydration followed by coat later cotyledons. changes status characterized NMR spectroscopy. Analyses T 2 relaxation times revealed a three‐component proton...
Research of the effect dicationic gemini surfactant (3,3′-[1,8-(2,7-dioxahexane)]bis(1-dodecylimidazolium) dichloride (C6IMIC12) on fibrillation process IVAGVN peptide using microscopic, spectroscopic and molecular docking techniques.
The changes in water distribution maturing lupin (Lupinus luteus L.) seeds were visualized with magnetic resonance imaging (MRI). MRI data showed local inhomogeneities of inside the seed. At late seed-filling stage most intense signal was detected seed coat and outer parts cotyledons hilum area, but during maturation drying decline MR image intensity faster part than central part. status characterized by NMR spectroscopy. Analyses T2 relaxation times revealed a three-component proton system...
Hydrogels are among the most promising materials for biological applications mainly because of their ability to absorb large volumes water and carry as well deliver biologically active substances. A challenge is make them appropriately responsive environmental triggering factors simply reliably. In this work, we present a basic approach modification commonly used, low-cost poly (acrylic acid) – PAA hydrogel with biocompatible surfactants regarding possible thermoresponsive...
Iron(III) complexes with N,O-ligands are compounds of high interest because they can be applied in catalysis and play an important role living organisms, e.g., as models catechol dioxygenase. Several were studied: their synthesis, iron(III) complexation the potential latter T1-MRI contrast agents. A route to tetrapodal N3O2-naphthyl ligand was investigated. The resulting iron complex obtained 26% total yield its relaxivity value moderate (r1 = 1.03 water 2.54 s−1 mM−1 serum). Thus, phenyl...
Self-assembled lipid nanoparticles containing Gd-chelating lipids are considered a new generation of positive Magnetic Resonance Imaging contrast agents (MRI CAs). High molecular weight imposes reduced reorientation (τr) and corresponding...
The integration of renewable energy resources into district heating systems is gaining momentum across Europe, as heat producers are expected to work towards the EU Directive Efficient District Heating and Cooling achieve carbon neutrality by 2050. This paper studies techno-economic implications transforming conventional six locations in Poland, generating 8.5 PJ annually, sustainable efficient systems. These new consist flat solar collectors integrated with seasonal pit thermal storages gas...
Novel contrast agents for magnetic resonance imaging based on hybrid MnO/lipids were developed and they discovered to be biocompatible efficient systems with future potential uses.
Dielectric relaxation profiles and self-diffusion coefficients were measured for 1,1,1-trichloroethane, t-butyl chloride, 2,2-dinitropropane in liquid plastic phases. For all threee samples no significant change the relaxational behavior is observed when going from to plastic-crystal The comparison of results with extended hydrodynamic model shows that overestimates effect translational-rotational coupling on dielectric properties liquids.
Abstract The analysis of the measured temperature dependences self‐diffusion coefficients for prolate ellipsoid type molecules α,ω‐dibromo‐methane, ‐ethane, ‐octane, ‐decane and ‐dodecane performed in frame modified Perrin model enabled to discover anisotropy translational diffusion liquids. On basis Eyring theory effect was confirmed jump length about 7 Å all derived. same longer obtained from Cohen‐Turnbull free volume theory.
We determine for the first time magnetic dipole moment of a short-lived nucleus with part-per-million (ppm) accuracy. To achieve this two orders magnitude improvement over previous studies, we implement number innovations into our $\beta$-detected Nuclear Magnetic Resonance ($\beta$-NMR) setup at ISOLDE/CERN. Using liquid samples as hosts obtain narrow, sub-kHz linewidth, resonances, while simultaneous in-situ $^1$H NMR measurement allows us to calibrate and stabilize field ppm precision,...
Polycrystalline cortisol (hydrocortisone; 11β,17α,21-trihydroxy-4-preg- nene-3,20-dione; C21H30O5) has been investigated by continuous and pulse proton NMR methods between 78 400 K at Larmor frequencies of 7, 25 60 MHz. A reduced value second moment was found above 90 is ascribed to reorientation two methyl groups. single asymmetric minimum in the temperature dependence spin–lattice relaxation times this also attributed The asymmetry suggests an distribution correlation motion.
