The nonexistence of heteroclinic travelling waves in an atomistic model for martensitic phase transitions is the focus of this study. The elastic energy is assumed to be piecewise quadratic, with two wells representing two stable phases. We demonstrate that there is no travelling wave joining bounded strains in the different wells of this potential for a range of wave speeds significantly lower than the speed of sound. We achieve this using a profile-corrector method previously used to show existence of travelling waves for the same model at higher subsonic velocities. 相似文献

The disruption of the human immunolobulin E-high affinity receptor I (IgE-FcεRI) protein-protein interaction (PPI) is a validated strategy for the development of anti asthma therapeutics. Here, we describe the synthesis of an array of conformationally constrained cyclic peptides based on an epitope of the A-B loop within the Cε3 domain of IgE. The peptides contain various tolan (i.e., 1,2-biarylethyne) amino acids and their fully and partially hydrogenated congeners as conformational constraints. Modest antagonist activity (IC(50) ~660 μM) is displayed by the peptide containing a 2,2'-tolan, which is the one predicted by molecular modeling to best mimic the conformation of the native A-B loop epitope in IgE. 相似文献

Phosphatidylcholine analogues were synthesised as affinity ligands for the capture of membrane proteins. Several protecting group strategies were investigated to synthesize the amino-functionalized phosphatidylcholine: 11-aminoundecyl 2-(trimethylammonio)ethyl phosphate (4). The acid-mediated deprotection of the Boc group generated a mixture of the target products which could only be purified by HPLC. However, an alternative strategy, using the hydrazine-labile phthalimide group route, followed by a gel filtration step proved straightforward to afford the desired amino-functionalized phosphatidylcholine product in high yield and purity. 相似文献

(1) is orthorhombic P212121 witha=9.3599(9),b=9.879(2),c=16.014(3), V=14803, Dc=3.03 Mgm–3 for Z=4. Structure solved by Patterson methods. Final R=0.038, Rw=0.038 [w=(2F)] for 1270 observed reflections and 141 parameters. Os3(CO)12Cl2
(2) is monoclinic C2/m witha=12.105(3), b=10.612(3),c=8.798(1) , =117.02(2)°, V=10063, Dc=3.22 Mgm–3 for Z=2. Structure solved by Patterson methods. Final R=0.036, Rw=0.037 (w=(2F)–) for 821 observed reflections and 75 parameters.Complex(1) has an osmium-osmium single bond 2.897(1), with the chloride ligands in equatorial positions,(2) has a linear triosmium chain with osmium-osmium single bonds 2.893(1) and the chloride ligands occupy equatorial sites on the terminal osmium atoms. Both(1) and(2) are isostructural with their osmium carbonyl iodide analogues. 相似文献
