IMPORTANCE OF THE FIELD: There exists a considerable unmet need for more efficacious delivery of ocular therapeutics. Contact lenses have been developed with high loading and controllable sustained release to overcome limited patient compliance and significant ocular transport limitations. This can best be achieved by…
TiO(2) nanomaterial is widely used for catalytic ozonation. In the present work, TiO(2) nanostructures with various morphology and crystallite phases were synthesized by a hydrothermal method, followed by calcination using Degussa P25 as precursor. The nanotube, nanorod, and nanowire forms were obtained by varying the…
Klar und deutlich: Ein leistungsstarkes und schnelles elektrochromes Display (ECD) mit passiver Matrix wurde aus einem Leukofarbstoff und einer nanoporösen TiO2-Elektrode konstruiert (siehe Bild). Die senkrechten Poren verhindern eine Bewegung der Farbstoffmoleküle und führen dadurch zu klaren Bildern bei hohen Freque…
The irradiation of an intense laser pulse onto a solid target immersed in liquid produces dense plasma. The plasma produced by liquid-phase laser ablation has unique features at high pressure and temperature, which are never realized by liquid-phase discharges. Another unique characteristic of liquid-phase laser ablat…
On display: A high-speed and high-quality passive-matrix electrochromic display (ECD) is constructed from a leuco dye and a TiO2 nanoporous electrode (see picture). The vertical pores prevent the drifting of the colored dye molecules, leading to a clear image at high driving speeds. With full-color features, this kind…
Abstract Hybrid dye‐sensitized solar cells are typically composed of mesoporous titania (TiO2), light‐harvesting dyes, and organic molecular hole‐transporters. Correctly matching the electronic properties of the materials is critical to ensure efficient device operation. In this study, TiO2 is synthesized in a well‐de…
Nanosized silica gel supported Ni catalysts that have average Ni particle size of 3.7, 11.4, and 11.8 nm were prepared by facile impregnation of different Ni precursors and used for hydrogenation of nitrobenzene (NB). These catalysts were characterized by N 2 adsorption, X-ray diffraction, and transmission electron mi…
The chemical and physical properties of [AgO 2 C(CH 2 OCH 2 ) 3 H] ( 3 ) and its use as an aqueous, ligand-free MOD ink (MOD = metal−organic decomposition) for piezo inkjet printing is discussed. The printed, thermal, or photochemical sintered silver features are electrically conductive on glass (2.7 × 10 7 S m −1 ) a…
The color of the incident light determines the efficiency of the hydrogen evolution mediated by a supramolecular photocatalyst. This finding demonstrates the importance of the Franck–Condon point in artificial photosynthesis systems and should have an impact on their design.
The concentration-dependent enhancement of the luminescence dissymmetry factor has suggested that pi-conjugated chiral perylene derivatives in a high concentrated opaque solution grow to aggregated structures with higher optical chirality.
Abstract Semitransparent inverted organic photodiodes are fabricated with a Baytron PH500 ethylene‐glycol layer/silver grid as the top electrode. Reasonable performances are obtained under both rear‐ and front‐side illumination and efficiencies up to 2% are achieved. Some light is shed on visual prospects through opti…
Enzymatic fuel cells convert the chemical energy of biofuels into electrical energy. Unlike traditional fuel cell types, which are mainly based on metal catalysts, the enzymatic fuel cells employ enzymes as catalysts. This fuel cell type can be used as an implantable power source for a variety of medical devices used…
Development of cancer receptor-specific gold nanoparticles will allow efficient targeting/optimum retention of engineered gold nanoparticles within tumors and thus provide synergistic advantages in oncology as it relates to molecular imaging and therapy. Bombesin (BBN) peptides have demonstrated high affinity toward g…
We report here the first attempt to produce and use whole acellular (AC) lung as a matrix to support development of engineered lung tissue from murine embryonic stem cells (mESCs). We compared the influence of AC lung, Gelfoam, Matrigel, and a collagen I hydrogel matrix on the mESC attachment, differentiation, and sub…
IMPORTANCE OF THE FIELD: Site-specific drug delivery is an important area of research that is anticipated to increase the efficacy of the drug and reduce potential side effects. Owing to this, substantial work has been done developing non-invasive and targeted tumor treatment with nanoscale metallic particles. AREAS C…
We present a study on the catalytic reduction of 4-nitrophenol by sodium borohydride in the presence of metal nanoparticles. The nanoparticles are embedded in spherical polyelectrolyte brushes, which consist of a polystyrene core onto which a dense layer of cationic polyelectrolyte brushes are grafted. The average siz…
In the present study, the hydrolysis behaviour of aluminum nitride (AlN) powder with and without dispersant [sodium tripolyphosphate (STPP, Na5P3O10) has been investigated in aqueous milling media to avoid hydrolysis and improve dispersion. The moderate amount of dispersant for good dispersion was found to be 0·015 g…
The exchange bias phenomena associated with the magnetic glass state at low temperatures in Gd5Ge4 are studied. The exchange bias effect originates from the exchange coupling between the ferromagnetic islands and antiferromagnetic matrix in the magnetic glass state. It is found that the exchange bias in Gd5Ge4 is stro…
Dried foam films (DFFs), which are free-standing reversed bilayers covering the holes of micrometers, are obtained by using several types of surfactants. In this article, we examined the formation of DFFs from a wide range of surfactants, systematically changing the headgroup, the counterion, the length and number of…
Both components of the tetragonal magnetoelastic constant b1: the saturation magnetostriction, λγ,2=(3/2)λ100, and the magnetic-field saturated shear elasticity, c′=(c11−c12)/2, were investigated over a wide temperature range for the magnetostrictive Fe1−x−yGaxGey alloys, (x+y≅0.125, 0.185, and 0.245; x/y≅1 and 3). Th…
