The present work is concerned with the fabrication of CO2 sensors based on MWCNTs/ZnO material, which is obtained by RF magnetron sputtering and electron‐beam deposition methods. The sensor exhibits highly sensitive and selective behavior, high repeatability, and temporal stability at low CO2 concentrations.

Electronic Materials with Wide Band Gap: Recent Developments [PDF]
The development of semiconductor electronics is shortly reviewed, beginning with the development of germanium devices (band gap $E_g=0.66$ eV) after world war II.

Analytic morphing of wurtzite nanowire cross sections to arbitrary shapes yields numbers of nanowire atoms, of bonds between these and of nanowire interface bonds, plus the nanowire cross section area. The ratios of above variables help to interpret any spectroscopic nanowire data which depend on diameter and cross section shape, and can be applied to ...

Ferromagnetism in sphalerite and wurtzite CdS nanostructures [PDF]
Abstract Room-temperature ferromagnetism is observed in undoped sphalerite and wurtzite CdS nanostructures which are synthesized by hydrothermal methods. Scanning electron microscopy and transmission electron microscopy results indicate that the sphalerite CdS samples show a spherical-like shape and the wurtzite CdS ones show a flower-like ...

Isotope‐Enriched Cubic Boron Arsenide with Ultrahigh Thermal Conductivity
The high‐quality isotope‐enriched cubic boron arsenide crystals that enhance the thermal conductivity of c‐BAs are synthesized and measured at a room temperature thermal conductivity of 1500 W m−1 K−1 for the c‐11BAs. This value is the highest thermal conductivity among known semiconductor materials.

Origin, ore forming fluid evolution and timing of the Logrosán Sn-(W) ore deposits (Central Iberian Zone, Spain) [PDF]
The Logrosán Sn–(W) ore deposits in the metallogenic Sn–W province of the European Variscan Belt consist of endo- and exogranitic greisen-type and quartz–cassiterite veins associated with a S-type granite. Mineral characterization, fluid inclusion study,

Resonant Spin Amplification and Accumulation in MAPbI3 Single Crystals
Carrier spin dynamics are studied in a 20 µm thin MAPbI3 perovskite single crystal using time‐resolved Kerr ellipticity at cryogenic temperatures. Long spin relaxation (30 ns) and dephasing (21 ns) enable spin accumulation. Spin accumulation effects are discussed in detail along with carrier‐nuclear spin interactions.

A mineral reconnaissance survey of the Abington-Biggar-Moffat-area, south-central Scotland [PDF]
Panned heavy mineral concentrates, mostly obtained from stream sediments, were collected from 195 sites in the Abington-Biggar-Moffat area. The project area, which lies immediately east of the formerly important mining district of Wanlockhead ...

Development of a Nb‐Based Semiconductor‐Superconductor Hybrid 2DEG Platform
Development of a new hybrid material using Nb and NbTi superconductors on an InAs quantum well using an epitaxial Al interlayer to prevent intermixing. Optimizing this structure lead to high‐quality interfaces and resulted in a Josephson junction with an induced superconducting gap of 1.0 meV. These results highlight the importance of interface quality
