Bimetallic systems present new opportunities to tailor the optical properties of nanoparticles. Morphology, structural, and optical properties of gold and of gold–silver nanoparticles have been studied by three-dimensional (3D) scanning transmission electron microscopy (STEM), STEM imaging, and monochromated subnanome…
Supramolecular nanofibers of prodrugs hold advantages for drug release due to their high drug payload, sustained and constant drug release behavior, and stimuli responsiveness. In this study, we report on a supramolecular hydrogel mainly formed by a clinically used drug triamcinolone acetonide (TA). Such a hydrogel co…
The fragility parameter has been acknowledged as one of the most important characteristics of glass-forming liquids. We show that the mystery of the dramatic change in molecular dynamics of systems approaching the glass transition can be better understood by the high pressure study of fragility parameters defined in d…
The investigation of the system Sm–Ba–Fe-O in air has allowed an oxygen deficient perovskite Sm 2-ε Ba 3+ε Fe 5 O 15-δ (δ = 0.75, ε = 0.125) to be synthesized. In contrast to the XRPD pattern which gives a cubic symmetry ( a p = 3.934 Å), the combined HREM/EELS study shows that this phase is nanoscale ordered with a q…
Conjugated phenylenevinylene oligoelectrolytes, which consist of a phenylenevinylene core equipped at each end with hydrophilic pendent groups, are shown to be good candidates for mammalian cell membrane staining. When used in the micromolar concentration range, they express low to moderate cell toxicity for selected…
In this article, we describe the engineering and X-ray crystal structure of Thermal Green Protein (TGP), an extremely stable, highly soluble, non-aggregating green fluorescent protein. TGP is a soluble variant of the fluorescent protein eCGP123, which despite being highly stable, has proven to be aggregation-prone. Th…
Photocured polymeric films are a promising candidate for the realization of flexible electronics, due to their easy processability, low cost, and availability. In this work, electrically conductive UV‐cured films have been prepared by irradiating an acrylic difunctional monomer in the presence of silver nitrate, pyrro…
We presented a comparative investigation on the morphological and structural properties of the produced ZnO nanowires (NWs) on c-Al2O3 substrates under different preparation conditions. The effects of a low-temperature nucleation layer, reaction pressure and light irradiation on the alignment, diameter and growth rate…
Recent findings show the emergence of two-dimensional electron gases (2DEGs) at LaAlO(3)/SrTiO(3) interfaces along different orientations; yet details on band reconstructions have remained so far unknown. Via x-ray linear dichroism spectroscopy, we demonstrate that crystal symmetry imposes distinctive 2DEG orbital hie…
The development of smart composites capable of self-repair in aeronautical structures is still at the planning stage owing to complex issues to overcome. It is critical that self-healing activity functions at low working temperatures which can reach values as low as −50 °C. Also, another problem concerns the component…
We investigate the controlled deposition of Keggin polyoxometalate (POM) anions, PMo 12 O 40 3– and PMo 12 O 40 2–, onto different self-assembled monolayer (SAM) surfaces via soft landing of mass-selected ions. Utilizing in situ infrared reflection absorption spectroscopy (IRRAS), ex situ cyclic voltammetry (CV), and…
Near-IR (NIR)-responsive drug delivery systems have received enormous attention because of their good biocompatibility and the high biological penetration of NIR. This work describes the facile fabrication and anticancer effect of a NIR-responsive drug delivery system based on the nano-assembly of mesoporous silica-co…
The authors study the optical properties of self-organized three-dimensional metamaterials, and explain their observations with a simple analytical model. These systems exhibit three outstanding features: a tunable plasmonic response orders of magnitude stronger than previously reported; operation in the visible, rath…
In the present paper, using a molecular dynamics simulation, we study a nature of melting of a two-dimensional (2D) system of classical particles interacting through a purely repulsive isotropic core-softened potential which is used for the qualitative description of the anomalous behavior of water and some other liqu…
Surface-enhanced Raman scattering (SERS) substrate of Ag nanostructure arrays patterned by porous anodic aluminum oxide (AAO) membrane supported on Al substrate (AAO/Al) were fabricated by electron beam evaporation technique. By introducing Al substrate, the optical and SERS properties of as-prepared AAO/Al-based Ag n…
In this article, we present a simple and fast optical method based on transmission microscopy to study the stochastic wetting transitions on micro- and nanostructured polymer surfaces immersed in water. We analyze the influence of immersion time and the liquid pressure on the degree of water intrusion in individual mi…
We report the fabrication of efficient white light-emitting diodes (WLEDs) based on Cu : ZnInS/ZnS core/shell quantum dots (QDs) with super large Stokes shifts. The composition-controllable Cu : ZnInS/ZnS QDs with a tunable emission from deep red to green were prepared by a one-pot noninjection synthetic approach. The…
In the area of cell-surface engineering with nanomaterials, the metabolic and functional activities of the encapsulated cells are manipulated and controlled by various parameters of the artificial shells that encase the cells, such as stiffness and elasticity, thickness, and porosity. The mechanical durability and phy…
A new type of a metasurface, known as a continuous metasurface, having only one trapezoidal antenna within a super cell, is proposed. Markedly different from previously reported discrete metasurfaces having multiple discrete antennas within a super cell, continuous metasurfaces can provide a continuously varying phase…
The transition temperatures of molecular ferroelectrics are usually lower than those of inorganic ferroelectrics due to weaker electron–electron and electron–phonon interactions in molecular ferroelectrics. Therefore, above-room-temperature molecular ferroelectrics are very rare which hinders their application in mode…
