We have systematically investigated the in-plane thermal transport in Si thin films using an approach based on the first-principles calculations and lattice dynamics. The effects of phonon mode depletion induced by the phonon confinement and the corresponding variation in interphonon scattering, which may be important for the thermal conductivities of… (More)
We isolated a novel strain D5 from nodules of Acacia confusa. Under strict sterile conditions the strain could successfully nodulate Acacia confusa, A. crassicarpa and A. mangium, with nitrogenase activity ranging from 18.90 to 19.86 nmol·g(-1)·min(-1). In the phylogenetic tree based on a complete 16S rRNA gene sequence, the sequence of strain D5 shared 99%… (More)
Single-crystalline Si-based nanocomposites have become promising candidates for thermoelectric applications due to their prominent merits. Reducing the thermal conductivity κ without deteriorating the electrical properties is the key to improve their performance. Through non-equilibrium molecular dynamics simulations, we show that κ of single-crystalline… (More)
Hemiberlesia pitysophila Takagi is an extremely harmful exotic insect in forest to Pinus species, including Pinus massoniana. Using both morphological taxonomy and molecular phylogenetics, we identified 15 strains of entomogenous fungi, which belong to 9 genera with high diversities. Surprisingly, we found that five strains that were classified as species… (More)

CoSb3-based skutterudites are promising intermediate-temperature thermoelectric materials and fundamental understanding of the thermal transport in CoSb3 is crucial for further improving its performance. We herein calculate the lattice thermal conductivity κL of CoSb3 with first-principles methods and conduct a comprehensive analysis on phonon mode… (More)
