Effect of water on crystallization and melting of telechelic oligo(ε‐caprolactone)s in ultrathin films

, 2021
The thermal behavior of ultrathin, semi‐crystalline films of oligo(ε‐caprolactone)s (OCLs) with hydroxy or methacrylate end groups, is studied by the Langmuir technique in dependence on mean molecular areas and crystallization temperatures.

Multiple temperatures and melting of a colloidal active crystal

Nature Communications
AbstractThermal fluctuations constantly excite all relaxation modes in an equilibrium crystal. As the temperature rises, these fluctuations promote the formation of defects and eventually melting. In active solids, the self-propulsion of “atomic” units provides an additional source of non-equilibrium fluctuations whose effect on the melting scenario is

Melting Point and Crystallization Temperature of Polyvinylidene Fluoride

Kobunshi Kagaku, 1970
ポリフッ化ビニリデンの加工性を明らかにする目的から, 溶融点および結晶化温度を測定した. 従来ポリフッ化ビニリデンの溶融温度として165～170℃が知られていたが, IRおよびDTA法などにより低温重合体の溶融温度は180～190℃であることが確認された. また結晶化温度は市販の高温重合体で約125℃, 低温重合体で約140℃が得られた. ポリフッ化ビニリデンは重合温度によってそれぞれ異なった値の溶融温度および結晶化温度を示し, それらの間には直線関係が見出された. IRスペクトルおよび核磁気共鳴吸収スペクトルの結果から, ポリフッ化ビニリデンの溶融および結晶化温度に及ぼす分子構造の影響について若干考察した.

'Phase transitions of a main-chain thermotropic copolyester: crystallization, melting behaviour and glass-transition studied by DSC

, 1995
The thermal behaviour of a main-chain thermotropic co-polyester has been investigated by Differential Scanning Calorimetry. Crystallization and melting have been studied through the effect of the annealing time and temperature on the transition ...

Smaller is better: nanobodies meet NMR

FEBS Letters, EarlyView.
Nanobodies are single‐domain antigen‐binding fragments derived from camelid heavy chain antibodies. Their small size, high stability, and exceptional specificity make nanobodies uniquely useful probes for NMR studies of protein dynamics, transient conformational states, and protein–protein interactions.

Derivation of intermediate to silicic magma from the basalt analyzed at the Vega 2 landing site, Venus. [PDF]

PLoS ONE, 2018
Geochemical modeling using the basalt composition analyzed at the Vega 2 landing site indicates that intermediate to silicic liquids can be generated by fractional crystallization and equilibrium partial melting. Fractional crystallization modeling using

Prediction of tensile modulus from calorimetric melting curves of polylactic acid with pronounced cold crystallization ability

Polymer Testing, 2021
The modulus of semicrystalline polymers mainly depends on two parameters of the crystalline structure, the crystallinity and the lamellae thickness. These parameters can be obtained from a single calorimetric melting curve, which makes it possible to ...
