Transport properties of Na8Si46
(2001-10)
We report on transport properties of polycrystalline Na8Si46 in the temperature range 10 to 300
K. The compound is a type I clathrate with Na incorporated into polyhedra formed by framework Si
atoms. Seebeck coefficient ...
First-principles study of the nuclear quadrupole resonance parameters and orbital ordering in LaTiO3.
(2009)
The electronic structure of the distorted perovskite LaTiO3 is studied using d.-functional
theory, implemented with a projector-augmented wave formalism together with the local-d. approxn.
plus Hubbard U-parameter (LDA+U) ...
High-throughput resistivity apparatus for thin-film combinatorial libraries
(2005-09)
An apparatus, capable of measuring the dc resistance versus temperature of a 49-member library
prepared by thin-film deposition techniques was designed and tested. The library is deposited by dc
magnetron sputtering onto ...
Technique for determination of accurate heat capacities of volatile, powdered, or air-sensitive samples using relaxation calorimetry
(2006-09)
We introduce a four-step technique for the accurate determination of the heat capacity of
volatile or air-sensitive samples using relaxation calorimetry. The samples are encapsulated in a
hermetically sealed differential ...
Spin waves and quantum criticality in the frustrated XY pyrochlore antiferromagnet Er2Ti2O7
(2008-10)
We report detailed measurements of the low temperature magnetic phase diagram of Er2Ti2O7. Heat
capacity and time- of- flight neutron scattering studies of single crystals reveal unconventional
low- energy states. Er3+ ...
Structural principles and amorphouslike thermal conductivity of Na-doped Si clathrates
(2000-07)
The postulated low thermal conductivity and the possibility of altering the electronic
conductivity of metal-doped clathrates with semiconducting host elements have stimulated great
interest in exploring these compounds ...
Genomic analysis of stationary-phase and exit in Saccharomyces cerevisiae: Gene expression and identification of novel essential genes
(2004-12)
Most cells on earth exist in a quiescent state. In yeast, quiescence is induced by carbon
starvation, and exit occurs when a carbon source becomes available. To understand how cells survive
in, and exit from this state, ...
