High-performance flexible thermoelectric modules based on high crystal quality printed TiS/hexylamine.

Printed electronics implies the use of low-cost, scalable, printing technologies to fabricate electronic devices and circuits on flexible substrates, such as paper or plastics. The development of this new electronic is currently expanding because of the emergence of the internet-of-everything. Although lot of attention has been paid to functional inks based on organic semiconductors, another class of inks is based on nanoparticles obtained from exfoliated 2D materials, such as graphene and metal sulfides.

Strong Reduction of Thermal Conductivity and Enhanced Thermoelectric Properties in CoSbSSe Paracostibite.

In order to reduce the thermal conductivity of CoSbS, a newly developed thermoelectric semiconductor, we have aimed at intentionally induce atomic disorder in its structure. This endeavor was guided by Density Functional Theory(DFT) calculations which indicated that substituting sulfur with selenium might be easily achievable experimentally because of the low formation energy of this point defect. Thereby, CoSbSSe compounds having 0 ≤ x ≤ 1 have been synthesized by solid state reaction.

Cognitive profile of school-age children and teenagers with hypohidrotic ectodermal dysplasia (HED).

Anhidrotic/hypohidrotic ectodermal dysplasia (HED) is the most common of the ectodermal dysplasias characterized by a triad of absent or reduced sweat, hypodontia and misshapen teeth, and missing or sparse hair. As the central nervous system is primarily ectodermal in origin, it has long been a concern that HED may be associated with developmental delay and/or intellectual disabilities. While published reviews report abnormalities in mental or motor development in 15-25% of HED-affected patients, there is no report in the literature including a systematic assessment of intellectual abilities in a cohort of patients with this rare disorder.

Integrated computational materials discovery of silver doped tin sulfide as a thermoelectric material.

Accelerating the discovery of new materials is crucial for realizing the vision of need-driven materials development. In the present study we employ an integrated computational and experimental approach to search for new thermoelectric materials. High-throughput first principles calculations of thermoelectric transport coefficients are used to screen sulfide compounds conforming to the boundary conditions of abundant and innocuous components.
