Abstract (sommario):

The article describes the dynamics of changes in the melt structure during cooling of solid substitution solutions in the process of quasi-equilibrium (CRC) and non-equilibrium explosive crystallization (NRCC), taking into account clustering processes. The boundaries of the transition to the solid state are determined as the structure of clusters changes during crystallizations of the KRK and NRK types. The boundaries are determined taking into account the critical overheating and pre-crystallization supercooling relative to the liquidus line . It is determined that during quasi–equilibrium crystallization, the melt changes its structure in the following sequence , and during non-equilibrium explosive crystallization - in the sequence . The phase rule is used to calculate the first crystals that appeared during various types of crystallization. Alloy cooling curves describing various types of alloy crystallization.

Abstract (sommario):

An automated platform for parallel crystallization of small organic molecules from solution is described. The principal gain over manual crystallization lies in the automated sequencing of crystallization steps, including computer-controlled dosing of liquids and solids. The platform is designed to conduct 32 crystallizations per day, from solution volumes up to 10 ml, allowing a search for physical forms to be conducted over a finer grid than might be accessible manually and thereby increasing the probability of success.

Abstract (sommario):

2,6-Dimethoxyphenylboronic acid was used as a model substance to investigate the additive crystallization approach for polymorph control in phenylboronic acids. It was crystallized under different conditions by performing evaporation and cooling crystallization from different solvents. Most of the crystallizations from pure solvents produced the thermodynamically stable Form I, but in evaporation crystallization from alcohols, Form II or even a new polymorph, Form III, could be obtained. Structurally related substances, polymers, and surfactants with diverse intermolecular interaction possibilities were tested as additives. Surfactants were found to facilitate the crystallization of the metastable forms and therefore were investigated more extensively. The surfactants Span 20 and n–octyl-β-D-glucopyranoside provided crystallization of the metastable forms in the evaporation crystallization and notably stabilized Form II. The lattice energy, energy frameworks, Hirshfeld surface analysis, full interaction maps, and morphology prediction were used to identify the structural differences between Forms I and II and rationalize the ability of the additives to provide formation of Form II in the crystallization and to stabilize it.

Abstract (sommario):

The study of the crystallization processes in the FINEMET type nanocrystalline amorphous alloy is interesting not only from the fundamental aspect of establishing reaction mechanism of crystal nucleation and growth, but also from a technological point of view. The process and nature of crystallization phase constitution of nanocrystalline amorphous alloy of composition Fe 73.5 Cu 1 Nb 3 Si 13.5 B 9 prepared by rapid quenching method is investigated in the present study. The amorphous nature of the alloy has been verified by x-ray diffraction (XRD). The differential thermal analysis (DTA) experiments were performed at different continuous heating rates of 10, 20, 30, 40 and 50 0 C/min. Two different crystalline phases are observed. The crystallization temperatures, the volume fraction of crystallizations and enthalpies of two different crystalline phases of the alloy have been determined from DTA traces. The dependence of on-set crystallization temperature (T x ) on the heating rate of different phases have been used for the determination of different crystallization parameters such as, the activation energy of crystallization, the order parameter or Avrami exponent (n). The results of crystallization were discussed on the basis of different models such as Kissinger’s approach and modification for non-isothermal crystallization of Matusita in addition to Kolmogorov, Johnson, Mehl, Avrami and Ozawa.

Abstract (sommario):

Polytetrafluoroethylene (PTFE) is a semi-crystalline polymer that demonstrates a very fast crystallization process on cooling. This study investigates the nonisothermal PTFE ultra-fast crystallization over a wide range of cooling rates via conventional Differential Scanning Calorimetry (DSC), Fast Scanning Calorimetry (FSC) and Ultra-Fast Scanning Calorimetry (UFSC). A new knowledge about crystallization kinetics of PTFE is obtained from the data obtained under very fast cooling rates. The shift of the melting peak to lower temperature shows that the crystals formed under fast cooling rates are slightly less stable than those produced under slower cooling rates. SEM analysis allows to observe these differences in crystal morphologies. According to the results, the crystallization is still present even for the fastest cooling rate employed and in consequences it is impossible to reach a metastable glassy state. The effective activation energy (Eα) displays a variation with the relative extent of crystallization (α) that is characteristic of a transition of PTFE crystallization from regime II to regime III around 312°C. Following the Hoffman-Lauritzen theory the Eα dependency obtained from the crystallizations under the different cooling rates was fitted in order to study the theoretical dependence of the growth rate.

Abstract (sommario):

Isothermal crystallizations in the supercooled liquid metal metastable state at progressively increasing temperatures above the Glass Transition of the Zr44-Ti11-Cu10-Ni10-Be25 metal glass Alloy (cold crystallization attained by heating the samples from the glassy state) have been investigated in this study.Complex crystallization behaviours showing multiple exothermic peaks and selective crystallization of the alloy higher mobility atoms induced by the isothermal annealing, has been observed to lead to experimentally observed increase of the temperature needed to induce the glassy metal relaxation (glass transition). DSC dynamic investigation indicated that only two atomic species that are present in the metastable liquid are involved in recrystallization process below 450-470°C. Isothermal annealing in the range of temperatures between 400° and 450°C has been chosen for further investigation on thermal events kinetics occurring in the super-cooled liquid. The activation energies associated to the two crystallization processes are, respectively, -181 kJ/mol and-262 kJ/mol

Abstract (sommario):

Polypropylene (PP)/microcrystalline cellulose (MCC) composites and PP/MCC composites modified by maleic anhydride grafted PP (PP-g-MA) and methyl acrylic acid glycidyl ester grafted PP (PP-g-GMA) respectively were prepared in a twin-screw extruder. The mechanical properties, morphology, and thermal performance were investigated. The nonisothermal crystallization, melting behavior, and nonisothermal crystallization kinetics were investigated by DSC. The results indicated that the addition of MCC had led to the increase of the tensile strength, impact strength, and flexural strength of PP. PP-g-GMA modification was more conducive to the improvement in tensile strength, impact strength, and flexural strength. The three types of PP/MCC composites have higher thermal decomposition temperatures, Vicat softening temperatures, and dimensional stability. Nonisothermal crystallizations of PP/MCC composites were in accordance with tridimensional growth with heterogeneous nucleation. Meanwhile, MCC was acted as the nucleating agent in PP matrix, which increased the crystallization temperature. PP-g-GMA further increased the crystallization temperature while PP-g-MA weakened the heterogeneous nucleation effect of MCC. Avrami equation and Mo method give a satisfactory description of the crystallization kinetics process. The activation energy of crystallization, nucleation constant, and fold surface free energy of PP were markedly reduced in PP/MCC composites and its compatibilized composites. The value of F( T) systematically increased with increasing relative degree of crystallinity. The addition of microcrystalline cellulose has greatly reduced the spherulitic size of PP.

Abstract (sommario):

On the basis of a statistical analysis of the data deposited in the Protein Data Bank [Bermanet al.(2000).Nucleic Acids Res.28, 235–242; Bernsteinet al.(1977).J. Mol. Biol.112, 535–542], it is shown that two symmetry-related protein molecules are frequently bridged by a small molecule/monoatomic ion, which was used in the crystallization medium despite the fact that it is not a physiological ligand of the macromolecule. It is therefore sensible to suppose that some of the solutes used in crystallizations can favour the nucleation process by bridging and opportunely orienting adjacent protein molecules. This would explain why small changes in the composition of the crystallization solution, for example, the presence of a minor amount of a specific additive, can have a dramatic impact on the outcome of a crystallization experiment.

Abstract (sommario):

The knowledge regarding certain issues in polymer crystallization e.g. the possible existence of short–lived mesophases remains inconclusive due to experimental limitations. Polymers undergo chain folding upon crystallization, which introduces some complications that are not found in crystallization of low molar mass materials. Chain–folded crystals are far from their equilibrium shape and they rearrange rapidly at the crystallization temperature. This, together with the slow experimental techniques traditionally used, impedes the observation of the originally formed structures. To approach this problem, molecularly constrained polymer structures (in which the crystallizing chains are fixed at one end whereas the other end is free to move) have been studied by X–ray diffraction, differential scanning calorimetry, polarized optical microscopy, transmission electron microscopy and atomic force microscopy. The crystallization studies performed in star–branched polyesters showed that the dendritic cores have a pronounced effect on the crystallization of the linear poly(ε–caprolactone) (PCL) arms attached to them. The star–branched polymers showed slower crystal rearrangement, higher equilibrium melting point, higher fold surface free energy, moderately lower crystallinity, and a greater tendency to form spherulites in comparison with linear PCL. The crystal unit cell was the same in both linear and star–branched PCL. Single crystals of the star–branched polymers were more irregular and showed smoother fold surfaces than linear PCL crystals. No sectorial preference was observed in the crystals of the star–branched polymers upon melting while the single crystals of linear PCL showed earlier melting in the {100} sectors than in the {110} sectors. Some of the differences observed can be attributed to the dendritic cores, which must be placed in the vicinity of the fold surface and thus influence the fold surface structure, the possibility of major crystal rearrangement and the presence of a significant cilia phase during crystal growth causing diverging crystal lamellae and consequent spherulite formation. The attachment of the many crystallizable chains to a single core reduces the melt entropy, which explains the higher equilibrium melting point of star–branched PCL. The crystallization behavior of a series of poly(ethylene oxybenzoate)s was also studied. The polymers showed a profound tendency for crystal rearrangement during melting even at high heating rates. The Hoffman–Weeks extrapolation method was found to be unsuitable to calculate the equilibrium melting point of the samples studied because the melting point vs. crystallization temperature data were sensitive to the variations in crystallisation time, which led to significant variations in the equilibrium melting points obtained.

ENGLISH ABSTRACT: This study involved the analysis of crystallization kinetics by means of a unique and newly developed Solution crystallization analysis by laser light scattering (Scalls) technique. In the main study we compared two commercial linear low-density polyethylene (LLDPE) polymers (PE-1- octene and PE-1-hexene) and studied the effect of short-chain branching on the solution crystallization of these complex polymer systems. Characterization of the polymers was done by nuclear magnetic resonance spectroscopy (NMR) and high-temperature gel permeation chromatography (HT-GPC). The second study involved the fractionation of a PE-1-hexene copolymer by temperature rising elution fractionation (Tref) and analyzing the solution crystallization of the different temperature fractions. This resulted in important details on the different molecular regions present in the polymer. A third additional study was done on the compatibility in polyolefin blends. Two different blends were prepared: isotactic polypropylene (iPP) – low density polyethylene (LDPE) blend and iPP – polypropylene impact copolymer (PPIC) blend. It was found that co-crystallization only occurred for the iPP - PPIC blends. Phase separation occurred for the iPP – LDPE blends, resulting in the formation of two phases for all blend compositions. Solution crystallization analysis is usually measured by the conventional Crystallization Analysis Fractionation (Crystaf) technique. In this study all crystallization data were compared with Crystaf results and a good correlation was found between the results obtained by Crystaf and Scalls. The major advantages of the Scalls technique are that, results similar to that of Crystaf can be acquired with much shorter analysis times and Scalls also allows for the measurement of solution melting of the crystallized polymer solutions.
AFRIKAANSE OPSOMMING: Hierdie studie het die analise van kristallisasie kinetika behels met behulp van die unieke en nuut ontwikkelde oplossing kristallisasie analise deur laser lig verstrooiing (Scalls) tegniek. In die hoof studie het ons twee kommersïele liniêre lae-digtheid polietileen (LLDPE) polimere (PE-1-okteen en PE-1-hekseen) vergelyk en die effek van kort-ketting vertakking op kristallisasie in oplossing van hierdie komplekse polimeer sisteme bestudeer. Karakterisering van die polimere was gedoen met kern magnetiese resonans spektroskopie (KMR) en hoë-temperatuur gel permeasie kromatografie (HT-GPC). Die tweede studie het die fraksionering van ‘n PE-1-hekseen ko-polieer met behulp van temperatuurstyging eluering fraksionering (Tref) behels asook die analisering van kristallisasie in oplossing van die verskillende temperatuur fraksies. Belangrike informasie oor die verskillende molekulêre areas teenwoordig in die polimeer was verkry. ‘n Derde addisionele studie was gedoen op die versoenbaarheid in poliolefin mengsels. Twee verskillende mengsels was voorberei: isotaktiese polipropileen (iPP) – lae digtheid polietileen (LDPE) mengsel en iPP – polipropileen impak ko-polimeer (PPIC) mengsel. Daar was gevind dat ko-kristallisasie slegs in die iPP – PPIC mengsel plaasgevind het. Fase skeiding het plaasgevind in die iPP – LDPE mengsels wat tot twee fases gelei het vir alle mengsel komposisies. Kristallisasie in oplossing word gewoonlik gemeet met die konvensionele kristallisasie analise fraksionering (Crystaf) tegniek. In hierdie studie was al die kristallisasie data met Crystaf resultate vergelyk en ‘n goeie korrelasie was gevind tussen die resultate van Crystaf en Scalls. Die grootste voordele van die Scalls tegniek is dat resultate soortgelyk aan diè van Crystaf kan verkry word met baie korter analises en Scalls laat ook toe vir die meting van smeltpunt van die gekristalliseerde polimeer oplossings.

In addition, an application for graphically simulating macroscopic crystal spherulite growth was developed for use as an educational tool. Finally, the experiment was used in the design process for modifying the generic iLab framework to incorporate interactive functionality. Specifically, a reservation model and design changes to the experiment storage and service broker were proposed based on the Polymerlab, and the experiment was used as a testbed for initial implementation of some of the proposed systems.

Abstract (sommario):

The crystallization kinetics of diphenylhydantoin (DPH) has been studied at constant conditions in a small mixed suspension mixed product removal (MSMPR) crystallizer. Supersaturation is created by changing the pH of a DPH solution in the crystallization vessel. Crystal size distributions (CSD's) are measured by an in situ zone sensing method. Effects of pH and supersaturation on crystallization kinetics and CSD are summarized. The effect of an additive on the crystal growth of DPH has been studied in a batch system. Avoidance of nucleation in the early stages of crystallization is essential to the effect investigated.

Abstract (sommario):

Crystallization behavior of different waxes such as beeswax (BW), paraffin wax (PW), ricebran wax (RBW), sunflower wax (SFW) was studied individually and in different oil solutions. Binary mixture at various proportions of the individual waxes was also explored in this study. Soybean oil is used in most of the study but olive, corn, sunflower, safflower, and canola oils were also explored. Lipid crystalline networks were characterized by several physical properties such as melting profile, solid fat content, viscoelastic parameters, cooling rate, phase behavior, crystal morphology. High intensity ultrasound (HIU) was used to change processing conditions of lipid crystallization. Instruments used to analyze the physical characteristics were differential scanning calorimeter, nuclear magnetic resonance spectroscopy, rheometer, temperature controlled water-bath, turbiscan light scattering device, and polarized light microscopy. The use of high intensity ultrasound showed that HIU technology can be used to delay the phase separation in beeswax/ oil system (canola, corn, olive, safflower, sunflower and soybean oil). Crystal sizes were reduced in beeswax/oil system at 0.5 and 1% concentration with the application of HIU technology. A study on binary waxes showed different phase behavior: eutectic behavior in BW/PW, SFW/PW, SFW/ BW, and RBW/BW; monotectic behavior in RBW/PW and continuous solid solution in RBW/SFW. Binary waxes in oil system (2.5% binary waxes) showed different physical properties when a range of binary blends were analyzed. Phase diagrams using iso-solid lines in binary wax/oil study show similarity when binary waxes without oil were studied using melting profile data. From all the above study it is understood that the physical properties of wax/oil systems are affected not only by the concentration and type of wax used, but also by the type of oil and application of HIU which induces wax crystallization and retards phase separation in wax/oil systems. Studies performed on all the topics suggest that understanding wax crystallization could help develop product formulation in food, pharmaceuticals, cosmetics, medicine and other industries.

Abstract (sommario):

In the work presented here, we use simulations of hard and nearly-hard spheres to examine the role of local structures in crystallisation. We are motivated by the work of Sir Charles Frank, who suggested that locally favoured structures, if incommensurate with crystalline ordering, could potentially suppress nucleation [1). Structural analysis is carried out using the topological cluster classification [2], which identifies those local arrangements of 5 < n < 13 particles which are structurally equivalent to the ground state structure for 11 particles considered in isolation. Initial work compares homogeneous crystallisation in simulation and experiment at the single particle level. Brownian dynamics simulations are carefully matched to a system of colloidal 'hard' spheres, taking both poly-dispersity and charge into account. In the regimes accessible, we find a reasonable agreement in the crystallisation rates, although the larger system size in experiments allows crystallisation to be observed at lower supersaturations than in simulation. Structural analysis of the metastable fluid finds a strong similarity between simulation and experiment, and in both we find large populations of five-fold symmetric local structures. We then move to examine what effect energetically favourable, five-fold symmetric local structures have on nucleation. A model hard sphere system with a novel many-body biasing potential is developed, which can be tuned to favour or disfavour the formation of pentagonal bipyramidal structures in the fluid . When the kinetic and thermodynamic effects of the biasing are decoupled, we find that Frank is correct, and that increasing the number of five-fold symmetric structures suppresses nucleation. Finally, in light of this finding, we explore the possibility of employing the structural biasing technique as a novel mechanism for a one component glass-former. Strongly biasing towards formation of five-fold symmetric structures results in unexpected phase behaviour and formation of an icosahedra-rich, Frank-Kasper phase is observed.

Abstract (sommario):

Examination of inclusions in minerals makes the basis for analyzing the peculiarities of salt crystallizationin the Kaliningrad-Gdansk halogen block of the Central- European evaporite basin. Most of the studied sections are composed of fine – medium- grained rock made of halite impregnated with polyhalite, kieserite, carnallite and kainite. Threesystemsofmicro-inclusionsmaybedistinguishedamongthe wide diversity of inclusions: 1) inclusions of mineral-forming mediums; 2) inclusions of surrounding mediums; 3) solid inclusions captured by minerals during their growth from marine solutions. Thedead-endpositionofthestudybasinaccounts for the solutions enrichment in potassium and magnesium arriving from the neighboring German-Polish halogen- bearing areas. Theinflowingbrinewas desalinated by continental waters enriched in calcium and sulfate ions. Thisusedtoresultincreating conditions for polyhalite precipitation. Thepresenceofflatboat-shapedstructuresin halite and in kainite grains is most probably indicative of surficial crystallization of potassium and potassium-magnesium minerals. Carnalliteandbischofiteimpregnationsarerecordedinhalite, whichis indicative of theeutonicstagein the basin development and of manifestations of bottom crystallization of minerals and, accordingly, of the brine probable stratification. Therefore, at the moment of crystallization of potassium and potassium-magnesium minerals, the basin was peculiar foravailabilityoftwo-layeredbrine.

Abstract (sommario):

Abstract The deformation behavior and mechanical properties of a Cu54Zr22Ti18Ni6 bulk metallic glass during and after deposition by kinetic spraying were investigated. The bulk metallic glass feedstock particles were manufactured by inert gas atomization and were subsequently deposited onto mild steel substrates by means of kinetic spraying at different powder carrier gas temperatures [room temperature, 450°C (within the supercooled liquid region), and 550°C (above crystallization temperature)]. In addition, the phase compositions of the feedstock and as-sprayed BMG coatings were investigated using X-Ray Diffraction (XRD), Differential Scanning Calorimetry (DSC), and Transmitted Electron Microscopy (TEM). With an increase of the powder feed temperature, it was deduced that more intimate contact of the particles with the substrate was achieved which decreased the porosity of the resulting coating. However, crystallizations, which seemed to be induced by severe deformation and accumulated heat, were observed at localized regions in the coating. In addition, micro-hardness and bond strength were affected by the crystallization degree of the as-sprayed coatings
