Prediction of Two-dimensional Phase of Boron with Anisotropic Electric Conductivity
(2017-03-01)
Two-dimensional (2D) phases of boron are rare and unique. Here we report a new 2D all-boron phase (named the π phase) that can be grown on a W(110) surface. The π phase, composed of four-membered rings and six-membered ...
One pot stimuli-responsive linear waterborne polyurethanes via Diels-Alder reaction
(Elsevier, 2019-01-25)
Different strategies were used to obtain waterborne polyurethanes containing Diels-Alder moieties. In the first one (two pot), furan and maleimide end capped waterborne polyurethane dispersions were synthesized with the ...
Thermal Stability of Endohedral First-Row Transition-Metal TM@ZniSi Structures, i = 12, 16
(ACS, 2011-03-31)
The thermal stability of first-row transition-metal-doped TM@ZniSi nanoclusters, in which TM stands for the first-row transition metals from Sc to Zn and i = 12, 16, has been analyzed for the two lowest-lying spin states ...
Vanishing efficiency of speeded-up quantum Otto engines
(IOP, 2019-08-28)
We assess the energy cost of shortcuts to adiabatic expansions or compressions of a harmonic oscillator, the power strokes of a quantum Otto engine. Difficulties to identify the cost stem from the interplay between different ...
