Relative modulus–relative density relationships in low density polymer–clay nanocomposite foams

open access: yesSoft Matter, 2011
Polymer–clay nanocomposite (PCN) foams represent an important class of new materials in structural engineering, biomedical fields and packaging. This paper reports the relative modulus–relative density relationship, a crucial correlation in cellular solids, for low-density PCN foams. Polyurethane (PU)–natural clay nanocomposite foams with a porosity of

Improvement of Short-Circuit Tolerance of Garnet Type Solid Electrolyte Li6.4La3Zr1.4Ta0.6O12 by Li2WO4 and Al2O3 Sintering Aids and La Deficiency

open access: yesElectrochemistry
Garnet-type Li6.4La3Zr1.4Ta0.6O12 (LLZT) is one of the most promising solid electrolytes for all solid-state batteries due to its relatively high Li-ion conductivity and electrochemical stability against Li metal anode. However, the presence of pores and

Exact solutions of Brans-Dicke cosmology and the cosmic coincidence problem

open access: yes, 2005
We present some cosmological solutions of Brans-Dicke theory, characterized by a decaying vacuum energy density and by a constant relative matter density.

Monotone Riemannian Metrics and Relative Entropy on Non-Commutative Probability Spaces

open access: yes, 1998
We use the relative modular operator to define a generalized relative entropy for any convex operator function g on the positive real line satisfying g(1) = 0.

Personalized Selumetinib Dosing in Pediatric Neurofibromatosis Type 1: Insights From a Pilot Therapeutic Drug Monitoring Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Objective To evaluate selumetinib exposure using therapeutic drug monitoring (TDM) in pediatric patients with neurofibromatosis type 1 (NF1) and plexiform neurofibromas (PN), assess interpatient pharmacokinetic variability, and explore the relationship between drug exposure, clinical response, and adverse effects.

Triton-3He relative and differential flows and the high density behavior of nuclear symmetry energy [PDF]

open access: yes, 2009
Using a transport model coupled with a phase-space coalescence after-burner we study the triton-3He relative and differential transverse flows in semi-central 132Sn+124Sn reactions at a beam energy of 400 MeV/nucleon.
