Then quenched at 100 °C min −1 to 60 °C for isothermal crystallization (20 min). Next, the sample was reheated to the self-seeding temperature (T b) for 3 min.Finally, cooled to −30 °C at 10 …
WebVarious approaches including laser induced crystallization technique has been reported to tackle this issue. We report on the crystallization of small- and macro-molecules under focused optical radiation from a femtosecond laser (λ = 800 nm). The efficacy of this technique is proved by crystallizing different samples such as sodium chloride ... WebOptical trapping-induced crystallization (OTIC) was first demonstrated by Sugiyama et al. in 2007 by focusing a near-infrared (NIR) laser in supersaturated glycine/D 2 O solution. When a laser beam is tightly focused in solution, optical gradient force attracts particles toward the focus spot [cf. optical trapping in Rayleigh regime described ...
WebApr 9, 2024 · At high flow strength, a flow-induced crystallization (FIC) occurred, producing a semicrystalline material possessing a high degree of crystallinity and primarily a monoclinic lattice structure. This FIC phase formed at a temperature (450 K) high above the quiescent melting point (≈400 K) and remained stable after cessation of flow for ...
CIMF was investigated on the series of synthesized PCLs. Initially, the PCL samples were exposed to simple heating. During the heating process (heating rate: 50 °C min−1), the PCL samples were completely molten at 70 °C, where they were kept for 2 min. Subsequently, the samples were cooled to 30 °C (cooling … See more In this study, polycaprolactone (PCL) was chosen as the crystalline polymer based on the following three considerations.
