The manganese-nitronyl-nitroxide two-dimensional coordination polymer {[Mn2(NITIm)3]ClO4}n (1) (NITImH = 2-(2-imidazolyl)-4,4,5,5-tetramethyl-4,5-dihydro-1H-3-oxide-1-oxyl) undergoes an unusual hysteretic thermo-induced valence tautomeric transition near room temperature, during which the manganese(II) ions are oxidized to manganese(III) and two of three deprotonated radicals (NITIm-) reduced their diamagnetic aminoxyl form (denoted NITRed2-). Upon cooling, high-temperature species...
Obtaining transparent glasses made of functional coordination polymers (CPs) represents a tremendous opportunity for optical applications. In this context, the first and red-emissive gold thiolate CPs have been obtained by simply applying mechanical pressure to amorphous powders CPs. The three gold-based CP are composed either thiophenolate [Au(SPh)] n , phenylmethanethiolate [Au(SMePh)] or phenylethanethiolate [Au(SEtPh)] . presence longer alkyl chain between phenyl ring led formation glass...
This study proposes a simple and novel synthesis route for rhombohedral single crystals (<2 μm) of magnesite. can be summarized by two main sequential reactions: (1) aqueous carbonation synthetic brucite (Mg(OH)2) injection CO2 in highly alkaline medium (2 m NaOH) at ambient temperature (∼20 °C), leading to precipitation platy-compacted aggregates dypingite (Mg5(CO3)4(OH)2·5H2O) after 24 h, (2) complete dypingite-to-magnesite transformation h heat-aging step from 20 90 °C. The implies the...
The first structure of a luminescent gold thiolate coordination polymer, [Au(SPh)]<sub>n</sub>.
The gas−solid carbonation of nanosized portlandite was experimentally investigated using a static bed reactor under anisobaric conditions. effects initial CO2 pressure (10−40 bar), reaction temperature (30 and 60 °C), relative humidity were investigated. Three steps the process determined: (1) instantaneous mineralization during injection period. From 25 to 40 wt % grains transformed into calcite period (from 0.9 2 min). (2) Fast after gas (<5 h) followed by (3) slow until an equilibrium...
ABSTRACT The thermal conductivity of polyimide/boron nitride (PI/BN) nanocomposite thin films has been studied for two sizes BN nanofillers (40 and 120 nm) a wide range content. A strong influence particle size on the conduction PI identified. In case largest nanoparticles (hexagonal‐BN), PI/h‐BN (120 increases from 0.21 W/mK (neat PI) up to 0.56 29.2 vol %. For smaller (wurtzite‐BN), PI/w‐BN nm), we observed different behaviors. First, see decrease until 0.12 20 % before increasing higher...
Abstract Herein, we present the successful synthesis and full characterization (by 11 B magic‐angle‐spinning nuclear magnetic resonance spectroscopy, infrared powder X‐ray diffraction) of sodium hydrazinidoborane (NaN 2 H 3 BH , with a hydrogen content 8.85 wt %), new material for chemical storage. Using lab‐prepared pure hydrazine borane (N 4 ) commercial hydride as precursors, was synthesized by ball‐milling at low temperature (−30 °C) under an argon atmosphere. Its thermal stability...
The present study describes a simple and novel synthesis route for submicrometric acicular goethite (α-FeOOH) using high OH/Fe molar ratio (=5) moderate temperature (30 70 °C). Two different alkaline sources (NaOH Ca(OH)2) two iron(III) (FeCl3·6H2O Fe(NO3)3.9H2O) were investigated. FESEM, XRD, FTIR, N2 sorption isotherms, color evolution, pH monitoring have been used to determine the formation mechanism, particle size, specific surface area, morphology of particles. Three regions determined...
Silicones such Sylgard 184 are widely employed in biological applications due to their versatile properties. However, inherently adhesive surfaces can restrict application, especially direct contact with damaged tissues, potentially compromising patient comfort. To enhance the surface properties of while maintaining its transparency visible spectrum, a novel low-temperature method (70 °C) has been developed. This involves immersing PDMS solution titanium (IV) ethoxide THF, thus inducing...
Oscillatory shear flow of poly[B-(methylamino)borazine] was studied for suitability as a melt-spinnable material. Shear rheology experiments show that viscosity molten is temperature dependent following an Arrhenius-type equation. The high value the activation energy caused by presence branched chains and cross-linked portions in polymer network which supply intrinsic rigidity to molecular architecture. Dynamic rheological properties polymers were measured at their spinning temperatures...
