Abstract:
In this contribution we analyze the influence of adsorption cycling, crystal size, and temperature on the switching behavior of the flexible Zr-based metal–organic framework DUT-98. We observe a shift in the gate-opening pressure upon cycling of adsorption experiments for micrometer-sized crystals and assign this to a fragmentation of the crystals. In a series of samples, the average crystal size of DUT-98 crystals was varied from 120 µm to 50 nm and the obtained solids were characterized by X-ray diffraction, infrared spectroscopy, as well as scanning and transmission electron microscopy. We analyzed the adsorption behavior by nitrogen and water adsorption at 77 K and 298 K, respectively, and show that adsorption-induced flexibility is only observed for micrometer-sized crystals. Nanometer-sized crystals were found to exhibit reversible type I adsorption behavior upon adsorption of nitrogen and exhibit a crystal-size-dependent steep water uptake of up to 20 mmol g−1 at 0.5 p/p 0 with potential for water harvesting and heat pump applications. We furthermore investigate the temperature-induced structural transition by in situ powder X-ray diffraction. At temperatures beyond 110 °C, the open-pore state of the nanometer-sized DUT-98 crystals is found to irreversibly transform to a closed-pore state. The connection of crystal fragmentation upon adsorption cycling and the crystal size dependence of the adsorption-induced flexibility is an important finding for evaluation of these materials in future adsorption-based applications. This work thus extends the limited amount of studies on crystal size effects in flexible MOFs and hopefully motivates further investigations in this field.

We performed systematic experiments on the synthesis of layered crystal α-ZrP and revealed the control of size, aspect ratio and size polydispersity of disk-shaped crystals. The growth of the disks is mediated by oriented attachment, taking place continuously throughout the hydrothermal treatment between various sized disks. The master of the synthesis of layered crystals will contribute to various applications such as the nanocomposites and liquid crystals.

Abstract:
Abstract The relationship among aspect ratio, initial size, and the evolution of the size spectrum is explored for ice crystals growing by vapor deposition. Ice crystal evolution is modeled based on the growth of spheroids, and the ice size spectrum is predicted using a model that is Lagrangian in crystal size and aspect ratio. A dependence of crystal aspect ratio on initial size is discerned: more exaggerated shapes are shown to result when the initial crystals are small, whereas more isometric shapes are found to result from initially large crystals. This result is due to the nature of the vapor gradients in the vicinity of the crystal surface. The more rapid growth of the smaller crystals is shown to produce a period during which the size distribution narrows, followed by a broadening led by the initially smallest crystals. The degree of broadening is shown to depend strongly on the primary habit and hence temperature.

Abstract:
This study evaluated Al-ZSM-5 nanocrystals grown from silicalite-1 seed crystals as catalysts for the methane dehydroaromatization (MDA) reaction. Silicalite-1 seed crystals sized between 30 and 40 nm were used to grow Al-ZSM-5 under various synthesis conditions. The size of Al-ZSM-5 was significantly affected by the Si/Al ratio (SAR), synthesis time, and silica nutrients/seed crystal ratio (NSR). Larger crystals were obtained with an increased SAR in the synthesis sols. Gradual growth of Al-ZSM-5 occurred with synthesis time, although the growth in crystal size ceased at 5 h of synthesis at 120 °C, indicating the rapid growth of Al-ZSM-5 aided by the silicalite-1 seeds. Precise tuning of Al-ZSM-5 size was possible by changing the nutrient/silicalite-1 seed ratio; a higher NSR led to larger crystals. Two representative Al-ZSM-5 crystals with SARs of 35 and 140 were prepared for catalyst testing, and the crystal sizes were tailored to <100 nm by controlling NSR. The MDA reaction was conducted in the presence of the prepared Al-ZSM-5. The catalyst size exhibited distinct differences in catalyst stability, while the SAR of catalysts did not produce noticeable changes in the catalyst stability of the Al-ZSM-5 crystals and commercial zeolites in this reaction system.

Abstract:
Modern reviews on crystal growth and defects in crystals overlook the fact that a significant portion of materials can spontaneously grow as single crystals with twisted and bent morphologies and curved crystal lattices. Twisted crystals can be found among all types of materials (molecular crystals, salts, minerals, high polymers, metals, and elements) crystallizing in any point and space group from all types of growth media (vapor, solution, gel, glass, melt, and solid state). Their size spans over more than six orders of magnitude ranging from nm where 3D character is equivocal, to cm or dm (some of the biggest natural crystals). Here are illustrated most important features of twisted crystals as well as an analysis of mechanisms that are responsible for this mysterious phenomenon [1]. In general, formation of a twisted crystal is a complex phenomenon involving with certain requirements for dissymmetry, isomorphism, and crystal chemistry. Also critical are processes at the crystal-medium interface as well as the elasticity and plasticity of the crystalline medium. As such, twisting is strongly controlled by morphology and symmetry of the growth face. It frequently requires impurities, sometimes in extremely low concentrations. The intensity of deformation is inversely proportional to the crystal size. The phenomenon is more common when the driving force for crystallization and the temperature are high. Several mechanisms have been proposed to explain the formation of unusual curved morphologies: axial dislocation in whiskers (Eshelby twist); surface stress in polymer lamellae; surface charge and spontaneous polarization in nanoribbons; inhomogeneous fields forming around a growing crystal; and internal stress created by an inhomogeneous impurity distribution. However, most of the mechanisms proposed are insufficiently developed and need further verification and elaboration.

Abstract:
Na0.5Bi0.5TiO3 is one of the potential candidates for non-lead piezoelectric materials to replace existing lead-based ones. Properties of BNT could be enhanced by reactive templated grain growth (RTGG) technique through induction of grain orientation with crystals of Bi4Ti3O12. Controlling the size of Bi4Ti3O12 crystals during the synthesis with molten salt is a major factor in optimizing RTGG. It was found that molten salt synthesis of Bi4Ti3O12 crystals with NaCl-KCl yielded larger particles, compared with Na2SO4-3K2SO4. Varying the proportion of chloride salt did not produce noticeable changes in crystal size. Bi4Ti3O12 crystals were significantly affected by raw materials treatment. Non-milling of starting powders could approximately double the crystal size

Abstract:
An understanding of the mechanisms of orientation of solutes in anisotropic solvents is of fundamental importance in the theory of liquid crystalline systems. A systematic study of these mechanisms is presently being conducted in this and other laboratories. As part of this investigation, the orientational order of a series of C[sub 2v] solutes in the liquid crystal mixture 55 wt% 1132 (Merck ZLI 1132) and 45 wt% partially deuterated EBBA (N-(4-ethoxybenzylidene)-2,6-dideutero-4-n-butylaniline) was studied using NMR spectroscopy. This technique provides a description of the average orientation of a solute in terms of the order parameters. The results obtained indicate a good correlation between order parameters and the size and shape of the solutes. A model based on short range hard body interactions, which depend on the dimensions of the solute, was used to predict orientational ordering. Excellent agreement was obtained between observed and calculated order parameters. These results provide supportive evidence that the mechanism responsible for orientation in the 55 wt% 1132 system is short range hard body interactions. A side study was conducted on the ordering of furan and thiophene in the liquid crystalline solvents 1132 and EBBA. Temperature dependence of order parameters in 55 wt% 1132 were examined. Orientation in 1132 and EBBA and temperature dependence in 55 wt% 1132 can be explained in terms of: (i) the short range interactions dependent on the dimensions of the solute, and (ii) the interaction between the molecular quadrupole moment of the solute and the average electric field gradient which is due to the solvent.

Abstract:
La cristallisation en continu de nanoparticules énergétiques est un défi de longue date. Le Spray Flash Evaporation (SFE) est une technique majeure développée et brevetée en interne, pour la production en continu de matériaux énergétiques submicroniques ou nanométriques ; la technologie se base sur la surchauffe d’un solvant pulvérisé dans le vide et s’évaporant de manière flash. Ce présent travail de recherche a pour but de comprendre et contrôler la cristallisation au sein du procédé SFE. Le RDX et le cocristal CL-20:HMX 2:1 sont étudiés. La sursaturation, concernant le SFE, est une fonction du temps et de l’espace liée aux tailles et vitesses de gouttes : elle fut variée par un anti-solvant et par l’amélioration du SFE avec un système double buse. Ensuite, PVP 40K et PEG 400 ont été utilisés afin de contrôler la nucléation et la croissance. Les particules ont pu être ajustées d’une taille de 160 nm à 5 µm, avec des morphologies facettées ou sphériques et avec des sensibilités moindres
The continuous formation of nanosized energetic material is a long-standing challenge. Spray Flash Evaporation (SFE) is a major technique, internally developed and patented, for continuously producing energetic materials at submicron or nano scale; it relies on the superheating of a solvent sprayed into vacuum and thus flashing. This present research project aims to understand and control the crystallisation occurring in the SFE process. RDX and the cocrystal CL-20:HMX 2:1 was studied overcome the limited in situ characterizations also. The supersaturation is a function of time and space in SFE, linked to the size distribution and velocity of droplets. Supersaturation was raised with an anti-solvent and by the enhancement of the SFE with a dual nozzle system. Then PVP 40K and PEG 400 were successfully used to alter the nucleation and the growth. The particles were subsequently tuned from 160 nm spheres to 5 µm grains and were less sensitive, especially toward electrostatic discharge

Abstract:
A crack propagation behavior of nano size hcp crystal (13nm × 24nm × 4.6nm) has been simulated by molecular dynamics method using Lennard-Jones type potential. In a case of model crystal with initial notch plane and direction were (1010), [1210], the crack propagated parallel to notch plane and two sets of prismatic slips were occurred at the crack. Therefore, the crack in this crystal is deduced to extend by alternating shear on two intersecting {1010}<1210> prismatic slip systems. In a model crystal with (0001), [1010] initial crack, {1011} first order pyramidal slip occurred at crack tip and following {1012} twin was also observed. In the model crystal with (1010)[0001] initial crack, the crack propagated parallel to initial crack plane with two prismatic slips in front of the crack. To understand strength of nano size titanium crystals as MEMS materials, stress intensity factor, K of each model crystals were also estimated from stress-strain curves obtained from these simulations.

Abstract:
Zeolite A crystals were synthesized at 100°C from sodium metasilicate and aluminium foil by microwave assisted hydrothermal technique. It was confirmed by using X-ray diffraction technique that zeolite A was produced. The influence of heating rate on the zeolite crystal size was investigated using 2.5°C/min, 7.5°C/min, and 50°C/min. It was shown that the low heating rate resulted in larger crystal size with high crystallinity. To evaluate the effect of crystal growth inhibitors (GCIs) on the zeolite synthesis and crystal size, three types of CGIs, namely Poly Ethylene Glycol (PEG); Poly Ethylene Glycol-Methyl Ether (PEG-ME); and Brij-96, were utilized. It was found that PEG gave the best result in terms of zeolite size compared to the other two CGIs by resulting in reduction of the size of zeolite A crystals into about half compared to that without CGI.

Abstract:
A larger size bucket with superior high temperature strength is required for future land based gas turbines. From the viewpoint of high temperature mechanical properties, single crystal alloys are rather promising. To grow larger sized single crystals of nickel base superalloys, a two stage heating and bypass process in which single crystal growth paths are incorporated into large cross sectional positions such as platforms has been developed. It results in successful single crystal growth of alloys for buckets with a total length of 170mm and large lateral cross section. Characteristics of single crystal buckets made by the bypass process and properties of an alumina mold prepared for a single crystal casting are described herein.
