Novel Thermoelectric Character of Rhenium Carbonitride, ReCN.

Nowadays, it is very important to study and propose new mechanisms for generating electricity that are environmentally friendly, in addition to using renewable resources. Thermoelectric (TE) devices are fabricated with materials that can convert a temperature difference into electricity, without the need for rotating parts. In this work, we report the TE properties of rhenium carbonitride (ReCN) as an important feature of a hard and thermodynamically stable material of band gap Δ = 0.

Pseudotumoral lesion as a manifestation of acute hemorrhagic leukoencephalitis (Weston-Hurst syndrome).

A case of acute hemorrhagic encephalomyelitis whose first manifestation was a pseudotumoral lesion in the corpus callosum is presented. The patient had an acute headache accompanied by visual hallucinations and subsequently developed convulsive status epilepticus. The initial CT scan showed a lesion with a pseudotumoral aspect in the splenius of the corpus callosum.

Youngswick-Austin versus distal oblique osteotomy for the treatment of Hallux Rigidus.

Background: Hallux Rigidus is the most common degenerative joint pathology of the foot. Several procedures are described for the management of this deformity. In this prospective study we compared Youngswick-Austin and distal oblique osteotomy in the treatment of grade II Hallux Rigidus, in terms of clinical outcomes, efficacy and complications.

Structure and stability of nanoscale bimetallic clusters.

This paper reviews the recent research and development of bimetallic clusters. Small bimetallic nanoscale clusters often have physical and chemical properties that are distinct from those of their pure bulk counterparts and suggestive of novel applications. Their chemical and physical properties can be controlled by varying the cluster size and composition as well as the temperature.

The surgical reconstruction of rheumatoid midfoot and hindfoot deformities.

Dealing with the rheumatoid midfoot and hindfoot is a challenging endeavor. There are numerous perioperative factors that influence surgical outcomes. This article provides a brief overview of the disease process and pertinent details on the surgical management of the rheumatoid midfoot and hindfoot.

Spin-zero sound in one- and quasi-one-dimensional 3He.

The zero sound spectrum of fluid 3He confined to a cylindrical shell is examined for configurations characterizing strictly one-dimensional and quasi-one-dimensional regimes. It is shown that the restricted dimensionality makes room to the possibility of spin-zero sound for the attractive particle-hole interaction of liquid helium. This fact can be related to the suppression of phase instabilities and thermodynamic phase transitions in one dimension.
