Confinement, spatial correlations and flexibility in the melting transition of DNA
La tesis estudia la fusión de ADN utilizando difracción de neutrones, difracción de rayos X y calorimetría. Las técnicas de difracción pueden acceder correlaciones estructurales en las moléculas durante la transición de fase que son definen la naturaleza de la transición pero son prácticamente …

Structure-property relationships of novel cellulose esters
… the C₁₂ - C₁₄ waxy tri-esters revealed separate melting transitions (T<sub>m,L</sub> and T<sub>m, H</sub>) for ester substituents and main cellulose chains, providing evidence for the existence of a separate (crystalline) phase formed by the ester substituents. Main-chain T<sub>mS</sub> of waxy …

Linking Thermophysical Transitions and Rheological Properties to Polymer Foaming Outcomes with Carbon Dioxide
… for the assessment of the depression in thermal transitions (Tg and/or Tm/Tc) and the changes in rheological properties like modulus or rigidity of polymer systems exposed to carbon dioxide. MSB provides for the assessment of the amount of carbon dioxide that sorbs into a polymer material at a …

Determining soft segment structure-property effects in the enhancement of segmented polyurethane performance
… sacrifice extensibility due to their high melting transition temperature. Moderately crystalline PEO soft segments, meanwhile, possess less defined phase segregation but enhanced mechanical properties from their reversible dispersed crystalline soft segment domains. Non-crystalline Pluronic …

Designing Acrylic Block Copolymers with Multiple Hydrogen Bonding or Multiple Ionic Bonding
… low polydispersity. Thermal analysis revealed a melting transition of the VBDC₁₈BrCl block copolymer resulting from the side-chain crystallization of the long alkyl tail. Systematic mechanical comparisons between DABCO salt-containing copolymers and the corresponding singly-charged polymer …

Crystallization and melting behavior of an aromatic semicrystalline polyimide, LaRC CPI-2
Research is presented on the crystallization and melting behavior of an aromatic semi crystalline polyimide known as LaRC CPI - 2 (Langley Research Center Crystalline rolyimide - second generation). This aromatic polyimide, a structural variant of the well known LaRC CPI, is synthesized froml …

Accurate Docking is Achieved by Decoupling Systematic Sampling from Scoring
… molecular dynamics: REMD). FSD-1's broad melting transition, similar to that of a helix-to-coil transition, was observed in CD, DSC, and REMD experiments. The N-terminal -hairpin was found to be flexible. FSD-1's apparent melting temperature of 41 degrees C may be a reflection of the …

Exploring the dynamic landscape of small molecule-DNA binding
… is related to the mechanism underlying the melting of short DNA sequence. It is important to gain a better understanding of these mechanisms as this process is thought to be important in DNA transcription, replication and repair as well as being important for the application and development …

Production of Polyhydroxyalkanoates by Pseudomonas mendocina using vegetable oils and their characterisation
… octanoate, coconut oil, and olive oil exhibited melting transitions, indicating that each of the PHA was crystalline or semi-crystalline polymer. In contrast, the thermal properties of PHAs produced from groundnut and corn oils showed no melting transition, indicating that they were completely …

Understanding correlations between secondary relaxations and thermal behaviour of biologically relevant molecules
… been examined at temperatures below the chain melting transition temperature (Tm). The results show that increasing the acyl chain length increases the temperature at which molecular mobility is observed i.e. the temperature maxima (Tmax) of the global relaxation processes occur at 41 ± 2, 47 …
