Butadiynyl-substituted h-benzeneCr(CO)3 complexes 3 are very efficiently prepared by a copper catalyzed coupling of the phenylacetylene complex 1 and bromo alkynes 2. The transmission of electronic effects through the butadiynyl bridge operates by resonance mechanisms as established by correlations between Hammett’s sp, sR and sP parameters. Most interestingly, however, is an unusual thermal be...
Polyethylene (PE) nanocomposites containing Cellulose Nano Crystal (CNC) were prepared via melt blending in a twin screw extruder. The evaluation of PE/CNC nanocomposites was studied for food packaging applications. The nanocomposites were investigated by thermal, mechanical analyses. Addition of CNC particle while having no effect on melting and crystallization temperature had intensive effect...
Wild strains of Arabidopsis (Arabidopsis thaliana) exhibit extensive natural variation in a wide variety of traits, including response to environmental changes. Ambient temperature is one of the major external factors that modulates plant growth and development. Here, we analyze the genetic architecture of natural variation in thermal responses of Arabidopsis. Exploiting wild accessions and rec...
[1] To understand the aqueous history of Mars, it is critical to constrain the alteration mineralogy of the Martian surface. Previously published analyses of thermal infrared (l = 6–25 mm) remote sensing data of Mars suggest that dark regions have 15–20% clay minerals. However, near-infrared (l = 1–3 mm) spectral results generally do not identify widespread clay minerals. Thermal infrared detec...
