This paper presents the growth and release process effects on the deformation of suspended gold micro-structures. Cantilever type test structures, typically used for RF MEMS devices have been examined. The structures have a thickness of 2μm, produced by patterned gold electro deposition above a sacrificial photoresist…
The synthesis of metal nanoparticles by femtosecond laser vaporization of nm-thickness metal films is explored with the goal of comparing the salient features of femtosecond-based through thin film laser ablation (TTFA) to that of ns TTFA, and testing the feasibility of direct synthesis of clean nanoparticle alloys to…
In many experimentally realized applications, e.g. photonic crystals, solar cells and light-emitting diodes, nanophotonic systems are coupled to a thick substrate layer, which in certain cases has to be included as a part of the optical system. The finite element method (FEM) yields rigorous, high accuracy solutions o…
We present the elegant synthesis and the photophysical and electroluminescent properties of a series of cyclometalated iridium(III) complexes [Ir(PPI)2(pic), PPI: 1,2‐diphenyl‐1H‐phenanthro[9,10‐d]imidazole; pic: picolinic acid]. The Ir(PPI)2(pic) complexes showed characteristic phosphorescence with an emission range…
This paper presents a working methodology to determine all the possible surface configurations of a hkl crystal face. As a case study, we have applied our strategy to individuate the surface configurations of the {100}, {110}, and {112} forms of pyrope (Mg 3 Al 2 Si 3 O 12 ). To identify the most stable surface termin…
The plasma outside deposition (POD) process is the basic technology for production of large core multimode silica fibers with highly fluorine doped cladding. Due to the all silica fiber construction such fibers can transmit several 10 kW of light power even with a core of 100 μm or less. An overview of the current cap…
[Co1.0/Pt0.75]n multilayers consisting of 1.0-nm-thick Co and 0.75-nm-thick Pt layers with n = 2–6 were grown on glass substrates with and without a Pt underlayer at room temperature (RT). In this study, the effects of total thickness and Pt underlayer on magnetic properties and microstructures are investigated. Witho…
Inorganic/organic hybrid coatings based on epoxy-polysiloxane resin were prepared by using five types of curing agents, including 3-aminopropyltriethoxysilane (APTES) alone (control coating) and the mixtures of four types of polyetheramines (Jeffamine D230, D400, T403, and THF100) along with APTES (modified coatings).…
New milestones in space exploration can be realized through the development of radiation-hardened, temperature-tolerant materials, sensors and electronics. This enables lightweight systems (reduced packaging requirements) with increased operation lifetimes. Gallium nitride (GaN) is a ceramic, semiconductor material th…
A point defect control scheme is demonstrated, to control point defects during the growth of doped wide bandgap semiconductors. First the theoretical description of this new concept is presented, second GaN:Mg is used as a model system and as an experimental example to show its feasibility. It can be shown that above…
We studied the activity of a debranching enzyme (TreX) from Sulfolobus solfataricus on glycogen-mimic substrates, branched maltotetraosyl-β-cyclodextrin (Glc₄-β-CD), and natural glycogen to better understand substrate transglycosylation and the effect thereof on glycogen debranching in microorganisms. The validation t…
Amphiphilic invertible polymers (AIPs) are a new class of macromolecules that self-assemble into micellar structures and rapidly change structure in response to changes in solvent polarity. Using small-angle neutron scattering (SANS) data, we obtained a quantitative description of the invertible micellar assemblies (I…
Advanced micro- and nanofabrication processes are constantly evolving from academic R&D environment towards real production technology. Therefore, the availability of suitable polymers for optical applications plays a crucial role to satisfy not only application based requirements but also the compatibility to industr…
We used high-resolution quantitative surface analysis to evaluate the surfaces of two aluminum automotive closure panel alloys, which were bent to a 180 deg angle in a simulated hemming test. Maps of the displacements normal to the sheet were superimposed on the topographies to correlate the location of the maximum di…
CrN monolayers along with CrN/SiC and CrN/diamond-like carbon (DLC) duplex layers were deposited by arc plasma acceleration on 4340 steel substrates. The layers exhibit a dense microstructure with a low density of surface defects and macroparticles. The tribological properties were evaluated with dry ball-on-disk slid…
In this first paper, the authors undertake a review of the literature in the field of ozone-assisted combustion in order to summarize literature findings. The use of a detailed n-heptane combustion model including ozone kinetics helps analyze these earlier results and leads into experimentation within the authors' lab…
Plasmonic solar cell is a very promising structure for high efficient solar cell application. It has some unique characteristics that allow high energy localization and higher solar energy absorption. Most of the proposed designs are based on using noble metals such as gold and silver to achieve the plasmonic effect.…
The compression behaviors of 2D plain woven basalt/vinyl ester resin composites along the thickness direction under high strain rates have been investigated experimentally and by use of finite element analyses. The compression stress–strain curves, compressive damage, and rate sensitivity of the compressive behaviors…
Selectivity is a critical issue in molecular recognition. However, design rules that underlie selectivity are often not well understood. Here, we studied five classical nuclear localization signals (NLSs) that contain the motif KRx(W/F/Y)xxAF and selectively bind to the minor site of importin α. The selectivity for th…
Abstract Dicationic viologen species are known to form strong supramolecular complexes with cucurbit[7]uril, as well as participate in electron‐transfer processes with donor systems. We describe the use of cucurbit[7]uril to modulate the electron transfer between a hybrid porphyrin (donor) and a viologen (acceptor) dy…
