Institutional designs to face the dark side of total allowable catches
(Oxford Journals, 2007)
Setting total allowable catches (TACs) is an endogenous process in which different agents and institutions, often with conflicting interests and opportunistic behaviour, try to influence policy-makers. Such policy-makers, ...
AZO Embedded IDEs for Monitoring Stimuli Responsive Materials
(Wiley, 2018-11)
A combination of atomic layer deposition and photolithography is applied to fabricate interdigitated electrodes of aluminum-doped zinc oxide embedded in polyethylene terephthalate substrates. Various designs with different ...
Upconversion cooling of Er-doped low-phonon fluorescent solids
(American Physical Society, 2009-01)
We report on a novel mechanism for laser cooling of fluorescent solids based on infrared-to-visible upconversion often found in rare-earth-doped low-phonon materials. This type of optical cooling presents some advantages ...
Synthesis of mechanically strong waterborne poly(urethane-urea)s capable of self-healing at elevated temperatures
(Elsevier, 2019)
Although various chemistries have been introduced into polyurethanes in order to obtain self-healing abilities, implementing these materials in applications requiring high strength is challenging as strong materials imply ...
Wheel-rail wear index prediction considering multiple contact patches
(Elsevier, 2009-06)
This paper shows a new wheel-rail contact model specially suited to obtain wear indexes between wheel and rail when the vehicle negotiates tight curves. The model presented in the paper enables introduction of the two ...
Exact-exchange Kohn-Sham potential, surface energy, and work function of jellium slabs
(American Physical Society, 2008-08)
Exact-exchange self-consistent calculations of the Kohn-Sham potential, surface energy, and work function of jellium slabs are reported in the framework of the optimized effective potential (OEP) scheme of density functional ...
Role of occupied d states in the relaxation of hot electrons in Au
(American Physical Society, 2000-07-15)
We present first-principles calculations of electron-electron scattering rates of low-energy electrons in Au. Our full band-structure calculations indicate that a major contribution from occupied d states participating in ...
Energy loss of charged particles moving parallel to a magnesium surface
(American Physical Society, 2008-10)
We present it ab initio calculations of the electronic energy loss of charged particles moving outside a magnesium surface, from a realistic description of the one-electron band structure and a full treatment of the dynamical ...
First-principles calculations of hot-electron lifetimes in metals
(American Physical Society, 2000)
First-principles calculations' of the inelastic lifetime of low-energy electrons in Al, Mg, Be, and Cu are reported. Quasiparticle damping rates are evaluated from the: knowledge of the electron self-energy, which we compute ...
Role of occupied d bands in the dynamics of excited electrons and holes in Ag
(American Physical Society, 2003)
The role that occupied d bands play in the inelastic lifetime of bulk and surface states in Ag is investigated from the knowledge of the quasiparticle self-energy. In the case of bulk electrons, sp bands are taken to be ...
