Crystallization, Melting Behavior, Physical Properties, and Physical Aging of Ethylene/1-Octene Copolymers
… assumptions: First, a single population of small crystals is formed during crystallization at low temperature; Second, these small crystals increase in stability under isothermal conditions, easily melt and recrystallize during heating and serve as efficient thermo-reversible cross-links to …

Microscopy of Gold Microcrystals by Coherent X -Ray Diffractive Imaging
"The small wavelength and penetrating nature of X-ray radiation has long been used to solve the structure of materials. Inherent in these measurements is the loss of phase information in the intensity measurement; the so-called ""phase problem."" Third generation synchrotrons provide X-ray beams …

An investigation of improvements to electrochemical precipitation of struvite from source separated urine
… to that, struvite generally precipitates as small crystals that are difficult to separate from the solution, leading to low mass recoveries of the product. These small crystals are formed as a result of the high supersaturation, which generally occurs for most processes that are employed to …

Melt Inclusion Geochemistry
Silicate melt inclusions (MI) are small samples of melt that are trapped during crystal growth at magmatic pressures and temperatures. The MI represent a sample of the melt that was isolated from the magma during host crystal growth. Thus, MI provide a valuable tool for constraining the magmatic …

Pharmaceutical crystallization design using micromixers, multiphase flow, and controlled dynamic operations
… discovery that a cooling micromixer can generate small crystals of uniform size and shape. An alternative design replaces the micromixing with the application of ultrasonication to decouple nucleation and flow rates. Based on these nucleation methods, a novel continuous crystallizer is designed …

Measurements of small ice crystals in arctic cirrus: observations from the Indirect and Semi-Direct Aerosol Campaign (ISDAC)
… uncertainty about the contributions of small ice crystals (maximum dimension D<50 µm) to the mass and radiative properties that impact radiative forcing. In situ measurements of small ice crystals in arctic cirrus were made during the Indirect and Semi-Direct Aerosol Campaign (ISDAC) in …

MITIGATION OF TEMPERATURE POLARIZATION AND MINERAL SCALING IN MEMBRANE DISTILLATION: THE IMPACT OF INDUCTION HEATED ELEMENTS
… analysis of membrane surfaces, only sporadic small CaSO4 crystals were detected, while high concentrations of small crystals were detected at the concentrate stream exiting the MD process. The scaling mitigation mechanism is hypothesized to be a result of the high-frequency movement and …

Biochemical and structural characterization of radical SAM enzymes Elp3 and viperin
… in the motif were mutated to serine residues. Crystals were obtained from the (6xHis)-MinElp3 C95S/C98S mutant. Also, using the optimized crystallization conditions, small crystals of wild-type MinElp3 were obtained. The functional characterization of Elp3 reported in our publication, along …

Evaluation of high intensity ultrasound on plant based lipid blends, containing health-promoting lipids, as an alternative to hydrogenation for plastic fat development
… (MCFA) and endogenous antioxidants. Due to their small size, MCFAs are more soluble and are absorbed without the use of bile, then readily oxidized by the liver. They are commonly consumed by individuals with fat malabsorption diseases and have been suggested for weight-loss. Endogenous …
