Insulation Workers

open access: yes, 2000
Insulation workers apply insulation materials on objects and buildings for thermal insulation and/or waterproofing. They are frequently outdoor workers and they are exposed to insulation materials, especially mineral fibers, foams, adhesives, and bitumen.

Topological Insulators and Superconductors from String Theory

open access: yes, 2010
Topological insulators and superconductors in different spatial dimensions and with different discrete symmetries have been fully classified recently, revealing a periodic structure for the pattern of possible types of topological insulators and ...

Topological crystalline insulator states in Pb(1-x)Sn(x)Se

open access: yes, 2012
Topological insulators are a novel class of quantum materials in which time-reversal symmetry, relativistic (spin-orbit) effects and an inverted band structure result in electronic metallic states on the surfaces of bulk crystals.

Theoretical analysis and application of polymer-matrix field grading materials in HVDC cable terminals

open access: yesHigh Voltage, 2017
The distortion and uneven distribution of electric field in high-voltage direct current (HVDC) terminal insulator is the key problem for stable running of the power transmission system.

Homotopy Theory of Strong and Weak Topological Insulators

open access: yes, 2014
We use homotopy theory to extend the notion of strong and weak topological insulators to the non-stable regime (low numbers of occupied/empty energy bands). We show that for strong topological insulators in d spatial dimensions to be "truly d-dimensional"

Metal particle movement and distribution characteristics under AC voltage and ball-plane electrodes

open access: yesHigh Voltage, 2019
Metal particles, difficult to be eliminated in gas-insulated metal-enclosed switchgear (GIS), can cause GIS discharge and breakdown between electrodes, or flashover on the insulator surface.

Topological insulators and thermoelectric materials

open access: yes, 2012
Topological insulators (TIs) are a new quantum state of matter which have gapless surface states inside the bulk energy gap. Starting with the discovery of two dimensional TIs, the HgTe-based quantum wells, many new topological materials have been ...

Superconductor–insulator transitions and insulators with localized pairs [PDF]

open access: yesPhysics-Uspekhi, 1998
Two experiments are described which are related to the problem of localized Cooper pairs. Magnetic-field-tuned superconductor-insulator transition was studied in amorphous In--O films with onset of the superconducting transition in zero field near 2 K. Experiments performed in the temperature range T>0.3 K indicate that at the critical field, B=B_c,
