Observation of the optical Rashba effect in plasmonics is reported. Polarization helicity degeneracy removal, associated with the inversion symmetry violation, is attributed to the surface symmetry design via anisotropic nanoantennas with space-variant orientations. By utilizing the Rashba-induced momentum in a nanosc…
A transmission ellipsometric method has been reformed without a spatial filtering aperture to characterize electro-optic (EO) performance of EO polymers. This method affords much simpler optical setup compared to the reflection method, and lets us easily perform detailed incident angle dependence measurements using a…
We have developed a new type of mechanically responsive material on the basis of a plasma-modified soft biomaterial substrate (polypropylene surgical mesh). A first plasma deposited layer, enriched in a bioactive agent (silver nanoparticles), has been covered by a second plasma polymer layer that acts as a barrier to…
A novel‐donor‐π‐acceptor‐type conjugated polymer based on the benzo[ c ][1,2,5]selenadiazole moiety and the fluorene group via an alkyne module is prepared by the the Sonogashira–Hagihara reaction. The polymer displays an absorption peak at a longer wavelength at 477 nm and shows orange fluorescence at 576 nm. The res…
Certain synthetic analogues of the green fluorescent protein (GFP) chromophore are almost nonfluorescent in dilute solutions but are strongly light-emissive in the solid state, thus exhibiting aggregation-induced emission (AIE) behavior. In the present work, two such hydrophobic derivatives of the GFP chromophore know…
This review presents recent research advances in defining the curing and thermal characteristics, mechanical properties and appropriate processing techniques of thermoset resin derived from vegetable oils. Vegetable oil is the latest alternative found to replace the dependence on petroleum-based synthetic resin. Petro…
Changes of the electronic and magnetic structure near the martensitic phase transition of Ni-Mn-In Heusler alloys doped with Co are investigated by experiment and theory. The nonstoichiometric Ni${}_{48}$Co${}_{5}$Mn${}_{35}$In${}_{12}$ epitaxial film undergoes a transition from a weakly magnetic martensitic phase bel…
The available data on the structural and magnetic transitions in multiferroic hexagonal YMnO3 have been reviewed, first making use of the computer programs from the group theoretical ISOTROPY software suite to list possible crystal and magnetic structures, then taking into account the capability of neutron diffraction…
Graphene substrates are known to have randomly located functional groups on their surface, particularly at their edges, including carboxylate, carbonyl, epoxy, and alcohol functionalities. However, the detailed interactions of these graphene functionalities with metal oxide nanoclusters are unexplored. This work exami…
The reaction of Ir 3 (CO) 9 (μ 3 -Bi), 1, with BiPh 3 has yielded a iridium–bismuth cluster complex Ir 5 (CO) 10 (μ 3 -Bi) 2 (μ 4 -Bi), 2 . The first examples of bimetallic iridium–bismuth nanoparticles have been subsequently synthesized from 1 and 2, and these have been securely anchored onto the inner walls of mesop…
Ab initio molecular dynamics simulations based on density functional theory were performed to generate amorphous models of the phase change compound In${}_{3}$SbTe${}_{2}$ by quenching from the melt. In-Sb and In-Te are the most abundant bonds with only a minor fraction of Sb-Te bonds. The bonding geometry in the amor…
Optical coatings based on ultrathin highly absorbing dielectrics on metals are attractive because of the considerable reduction of their thickness compared to conventional dielectric coatings. We demonstrate that the underlying material of these optical coatings is not limited only to metals as assumed previously. Ins…
We apply the concept of quasicrystals to metamaterials and experimentally demonstrate metasurfaces with isotropic properties and high resonance strength. By comparing quasicrystalline, periodic, and amorphous metasurfaces we quantify the impact of symmetry on their properties. This is achieved by studying the eigenpol…
This article focuses on the formation of the surface tension torque (STT) phenomenon close to the dry-line boundary layer during evaporation of the liquid phase of a solution casted shape-anisotropic nanoparticle suspension (here, cellulose nanowhisker (CNW)) or dissolved polymer (here, polyvinyl alcohol (PVA)) and it…
In this paper, we describe the use of a temperature responsive polymer to reversibly assemble gold nanoparticles of various sizes. Temperature responsive, low critical solution temperature (LCST) pNIPAAm-co-pAAm polymers, with transition temperatures (T(C)) of 51 and 65 °C, were synthesized with a thiol modification,…
Colloidal synthesis of kinked ultrathin ZnS nanorods/nanowires with mixed phases using tiny Ag2S nanocrystals as catalysts is reported. It is found that chloride ions can induce the controlled morphology transition from straight to kinking. The synthetic parameters modulating the growth of kinked ZnS nanorods/nanowire…
Dynamic heterogeneity was investigated for the first time in a conductive organic ionic plastic crystal by molecular dynamics simulation. A minority fraction of ions that possess above-average dynamics were identified in the plastic crystal phase. The signature of this unusual motional behavior is found in the signifi…
Graphene oxide (GO) is an important precursor in the production of chemically derived graphene. During reduction, GO's electrical conductivity and band gap change gradually. Doping and chemical functionalization are also possible, illustrating GO's immense potential in creating functional devices through control of it…
Nanoparticle based drug delivery systems are gaining popularity due to their wide spectrum advantages over traditional drug delivery systems; among them, dendrimeric nano-vectors are the most widely explored carriers for pharmaceutical and biomedical applications. The precise mechanism of encapsulation of drug molecul…
A superhydrophobic pillar-structured electrode leads to uncommon electrochemical behavior. The anti-wetting reaction surface restricts the contact between electrolyte and electrode to the pillar tops, as a result of trapped air pockets in the gaps between pillars. The electrochemical reaction occurs mainly at the soli…
