Augmentation of bone defect healing using a new biocomposite scaffold: an in vivo study in sheep

Dominique Pioletti, Pierre-Etienne Bourban

Previous studies support resorbable biocomposites made of poly L-lactic acid (PLA) and β-tricalcium phosphate (TCP) produced by supercritical gas foaming as a suitable scaffold for tissue engineering. The present study was undertaken to demonstrate the bio ...

Atomistic simulations of nanometric dislocation loops in bcc tungsten

Robin Schäublin

Small dislocation loops formed from self-interstitial atoms (SIAs) are commonly found in irradiated metals. These defects signiﬁcantly inﬂuence the mechanical properties of the materials. Atomistic simulations are used to describe nanometric circular dislo ...

HREM studies of twins in Cd1−xZnxTe (x ≈ 0.04) thin films grown by molecular beam epitaxy

Nava Setter, Marco Cantoni

The microstructure of ferroelectric Cd1−xZnxTe (CZT) thin films with x ≈ 0.04 grown by molecular beam epitaxy has been studied by means of cross sectional high-resolution transmission electron microscopy (HREM). High- density {1 1 1} lamellar twins are fou ...

Defect of characters of the symmetric group

Following the work of B. Kulshammer, J. B. Olsson and G. R. Robinson on generalized blocks of the symmetric groups, we give a definition for the l-defect of characters of the symmetric group G(n), where l > 1 is an arbitrary integer. We prove that the l-de ...

Intrinsic defects in CdTe and CdZnTe alloys

Nava Setter, Alexander Tagantsev, Alexandra Sarabando de Carvalho

The Cd vacancy (VCd) and Te anti-site (TeCd) are two dominant defects in CdTe and CdZnTe alloys grown in Te-rich conditions. We examine the properties of these two intrinsic defects in Cd1-xZnxTe alloys with x

Effect of thermal expansion, electronic excitations, and disorder on the Curie temperature of Ni1-xCuxMnSb alloys

We demonstrate the importance of thermal effects such as temperature-induced electronic, magnetic and vibrational excitations, as well as structural defects in the first-principles calculations of the magnetic critical temperature of complex alloys using h ...

Charge transition levels of the Ge dangling bond defect at Ge/insulator interfaces

Alfredo Pasquarello, Peter Broqvist, Audrius Alkauskas

We calculate defect levels of dangling bonds in germanium using hybrid density functionals. To validate our approach, we first consider the dangling bond in silicon finding two well-separated defect levels, in excellent correspondence with their experiment ...

Defect levels of dangling bonds in silicon and germanium through hybrid functionals

Alfredo Pasquarello, Peter Broqvist, Audrius Alkauskas

Defect levels of dangling bonds in silicon and germanium are determined within their respective band gaps through the use of hybrid density functionals. To validate our approach, we first considered the dangling bond in silicon finding two well-separated d ...

Analysis of nano-sized irradiation-induced defects in Fe-base materials by means of small angle neutron scattering and molecular dynamics simulations

Gang Yu

Thermonuclear fusion of light atoms is considered since decades as an unlimited, safe and reliable source of energy that could eventually replace classical sources based on fossile fuel or nuclear fuel. Fusion reactor technology and materials studies are i ...

The Real Value of Testing

James Richard Larus

A decade ago, Tony Hoare noted that "The real value of tests is not that they detect bugs in the code but that they detect inadequacies in the methods, concentration, and skills of those who design and produce the code." As usual, Tony saw far ahead of the ...
