In this study, we have prepared tumor-targeted hydrophilic UCNPs by coating folate-modified amphiphilic SOC polymer on the surface of OA-UNCPs through hydrophobic interaction. The produced FASOC-UCNPs have excellent optical properties and good dispersibility in aqueous solution. TEM image and FTIR spectra confirm the…
Using refined density functional theory approaches, we investigate the structure and spectroscopic signatures of recently synthesised oxasmaragdyrin dyes. Besides comparisons between theoretical and experimental nuclear magnetic resonance (NMR) chemical shifts, we analyse the electronic excited states of two boron com…
Mehrwandige Kohlenstoffnanoröhren wurden teilweise entrollt, um durch Nanobänder verbrückte Nanoröhren zu erhalten. M. Liu, H. Peng und Mitarbeiter zeigen in ihrer Zuschrift auf S. 4088 ff., dass solche Strukturen einen schnellen Ladungstransport begünstigen. Farbstoffsolarzellen mit Gegenelektroden aus diesem Materia…
The multispectral imaging technique consists of imaging a given scene at various wavelengths of interest, each one containing a different spectral information. By analyzing this spectral content, the chemical species that are present can be localized on the image and identified by reconstructing their spectral signatu…
Surface-enhanced Raman spectroscopy (SERS) has been widely used for high-sensitivity molecular detection and identification. It is advantageous for a SERS substrate to have a large surface-to-volume ratio from the standpoint of high density “hot spots” and optical sampling efficiency. In this paper, we show that monol…
Plasmonics mainly deals with light-matter interactions in metallic nanostructures. It has gathered interest since its discovery due to the benefits it provides when compared with photonics and electronics. It owes its popularity to the tremendous number of applications it serves for. In this paper, we review how plasm…
In this manuscript, a new near-infrared (NIR) light-breakable amphiphilic block copolymer containing light-sensitive triggering group on the hydrophobic block was developed. By encapsulating NIR dye cypate inside micelles of poly (N-succinyl-N'-4- (2-nitrobenzyloxy)-succinyl chitosan) and exposing the micellar solutio…
Viscoelastic shear waves (VESW) propagation in soft matters such as gelatin under thermal steady state was studied. VESW in a slab of gelatin causes the transverse displacement of the surface in a harmonic wave. The harmonic oscillation frequency of the transverse displacement of gelatin surface was then measured in r…
A facile divergent synthesis of a phosphorus-containing dendron containing 1,5-diaminonaphthalene is described. The phosphorus-containing dendron, functionalized with a 1,5-diaminonaphthalene unit at the core and phenolic OH groups grafted at the periphery, has been accomplished in a versatile, simple fashion, using S…
The crystals of the title compound were obtained from the reaction of (NH4)2[MoO2S2], CuI, and BPHEP·I2 [BPHEP = 1,7-bis(pyridinium) heptane] in DMF solution. The cluster anion consists of two nest-shaped fragments interconnected through a four-membered Cu(I)2Cu ring. The structure of the cluster has been characterize…
The photoionization of Cr at excited states is investigated using a velocity-map photoelectron imaging technique. Benzene chromium carbonyl or bis(η(6)-benzene) chromium was used as a precursor for the generation of excited Cr atoms. The a (5)S2 → x (5)P°3 and a (5)D3 → y (5)D°2 transitions are then employed for the p…
In the present work we investigated the properties and behavior of plasmonic modes of silver nanocube monolayers with respect to reflection and transmission of visible radiation. Uniform monolayers of low particle densities were created using the Langmuir-Blodgett technique using the phospholipid 1,2-dioleoyl-sn-glyce…
We describe approaches to enhance localized surface plasmons by placing metallic nanoparticles into two different structures: (i) Fabry-Perot (F-P) resonant cavities, and (ii) Photonic crystal slot waveguides. Through synchronization of the plasmonic and resonant modes, electric field at the surface of the nanoparticl…
The authors present a dimeric complex prepared by hydrothermal process with the formula {[Cu (bpdc) (H2O)] 2·2H2O}, (H2bpdc = 2, 2′-bipyridyl-6, 6′-dicarboxylic acid). This molecule has been characterized by X-ray crystallography and the crystallography reveals that it crystallizes in triclinic space group P–1 with th…
The morphology of organic components, especially their micro/nanostructures, plays a key role in the fabrication of organoelectronic devices. A team of researchers led by Qichun Zhang has successfully integrated an electron-deficient N-substituted oligoacene moiety and an imide-substituted naphthalene unit into a nove…
Extraordinary optical transmission through a subwavelength aperture was discovered more than a decade ago. A single subwavelength aperture surrounded by a finite array of grooves on a thin metallic film is a design used by many authors to show subwavelength focusing. In this paper, a modified version of this design is…
