Depositing a fused-ring thieno-thiophene polymer on different self-assembled monolayers indicates that varying the SAM surface energy changes the FET mobility and turn-on voltage by varying polymer crystallinity at the buried interface.

We measured electron density and electron energy distribution function (EEDF) in our reactor by a Langmuir probe. The EEDF of Ar plasma in the reactor could largely be described by the Maxwell-Boltzmann distribution function, but it also contained a fraction (~10) of electrons which were much faster (20-40 eV). The peak of the fast-electron tail shifted from E ~ 35 eV at 11 μbar to E ~ 25 eV wh...

Hybrid photocatalysts were prepared by depositing a macrocyclic cobalt complex on TiO2 surfaces. Upon UV light irradiation, photoexcited electrons in TiO2 nanoparticles were transferred to the surface cobalt catalyst for CO2 reduction.

Vacuum-deposited perovskites provide a more direct path to manufacturing large area solar cells because of ready compatibility with multilayered architectures and historic use in the electronics industry. However, vacuum compatible co-deposition organic-inorganic remains difficult due issues precisely controlling organic precursor flux. Here, we demonstrate prototype specifically designed for c...

This paper presents a new deposition process for directly building cylindrical parts of the 5356 aluminium alloy with variable polarity gas tungsten arc welding (VPGTAW). The relationship between the geometric sizes of the deposited layer and the welding parameters is investigated. A machine vision sensor is used to monitor and control the arc length that is a key welding parameter in the achie...
