The objective of the present investigation is to develop and characterize anionic mixed micelles of two biocompatible surfactants, Tween 80 (T-80) and sodium deoxycholate (NaDC), and evaluate their potential in the delivery of doxorubicin hydrochloride (DOX), a cationic anticancer drug. The mixed micelles were charact…
Stacks of multilayered rutile TiO(2) nanoflowers can grow on a titanium film through a simple acid vapour oxidation (AVO) method. The growth of this interesting hierarchical architecture is due to the formation of rutile {101} twinned structures and a subtle mismatching between the lattice spacings of the substrate an…
Nanotechnology is poised to impact the food and food-related industries through improvements in areas as diverse as production, packaging, shelf life, and bioavailability of food and beverage components. An evaluation was undertaken to characterize the published literature pertaining to the safety of oral exposure to…
Small interfering RNA (siRNA) has emerged as a therapeutic strategy for various diseases due to its target-specific gene silencing; however, its relatively high molecular weight, negative charge, and low stability hamper in vitro and in vivo applications. Approaches to overcome those drawbacks have relied on nonviral…
A water-soluble manganese porphyrin, 5,10,15,20-tetrakis-(1,3-dimethylimidazolium-2-yl)porphyrinatomanganese(III) (Mn(III)TDMImP) is shown to react with H(2)O(2) to generate a relatively stable dioxomanganese(V) porphyrin complex (a compound I analog). Stopped-flow kinetic studies revealed Michaelis Menton-type satura…
Der Schlüssel für die ungewöhnlich hohe Leistung der auf Metall-organischen Gerüsten (MOFs) beruhenden ZIF-90/6FDA-DAM Membran (leerer rosafarbener Kreis im Diagramm, jenseits der oberen Grenze für Polymermembranen) bei der CO2/CH4-Trennung ist die Kombination eines hoch selektiven MOF in Form submikrometergroßer Kris…
We quantify the efficacy of flow-through nanohole sensing, as compared to the established flow-over format, through scaling analysis and numerical simulation. Nanohole arrays represent a growing niche within surface plasmon resonance-based sensing methods, and employing the nanoholes as nanochannels can enhance transp…
The encapsulation and release of peptides, proteins, nucleic acids, and drugs in nanostructured lipid carriers depend on the type of the self-assembled liquid-crystalline organization and the structural dimensions of the aqueous and membraneous compartments, which can be tuned by the multicomponent composition of the…
An atomistic cluster alignment method is developed to identify and characterize the local atomic structural order in liquids and glasses. With the ``order mining'' idea for structurally disordered systems, the method can detect the presence of any type of local order in the system and can quantify the structural simil…
Abstract Room temperature acetalization of aldehydes with methanol has been carried out using metal organic frameworks (MOFs) as solid heterogeneous catalysts. Of the MOFs tested, a copper‐containing MOF [Cu 3 (BTC) 2 ] (BTC=1,3,5‐benzenetricarboxylate) showed better catalytic activity than an iron‐containing MOF [Fe(…
Abstract Efficient charge transport in organic semiconductors is the key for their application in Organic Electronics. Therefore the most important design ansatz is directed to improve carrier mobilities by means of available tools such as chemical and/or structural modifications of the organic materials. Thereby theo…
We show here that hyperpolarized [1-(13) C]pyruvate can be used to detect treatment response in a glioma tumor model; a tumor type where detection of response with (18) fluoro-2-deoxyglucose, using positron emission tomography, is limited by the high background signals from normal brain tissue. (13) C chemical shift i…
Tubular microporous organic networks bearing imidazolium salts (T-IM) were prepared by Sonogashira coupling of tetrakis(4-ethynylphenyl)methane and diiodoimidazolium salts, which showed promising catalytic activities in heterogeneous conversion of CO(2) into cyclic carbonates.
Controlled radical polymerizations (CRP) were pioneered in the late 1970s. Since then, tremendous investigations have been developed, especially from mid-1990s which generated much enthusiasm on CRP. However, the extraordinary scientific development of CRP contrasts with the limited number of commercially available pr…
The elastic moduli of polythiophenes, regioregular poly(3-hexylthiophene) (P3HT) and poly-(2,5-bis(3-alkylthiophene-2-yl)thieno[3,2-b]thiophene) (pBTTT), are compared to their field effect mobility showing a proportional trend. The elastic moduli of the films are measured using a buckling-based metrology, and the mobi…
Silicon is a high refractive index material. Consequently, silicon nanowires (SiNWs) with diameters on the order of the wavelengths of visible light show strong resonant field enhancement of the incident light, so this type of nanomaterial is a good candidate for all kinds of photonic devices. Surprisingly enough, a t…
The use of the total acid number (TAN) method for measuring the acidity of biomass fast pyrolysis bio-oil was evaluated. Suggestions for carrying out the analysis have been made. The TAN method by American Society for Testing and Materials (ASTM) D664 or D3339 can be used for measuring the acidity of fast pyrolysis bi…
The integration of negatively charged single-metal building blocks {In(CO2)4} and positively charged trimeric clusters {In3O} leads to three unique cage-within-cage-based porous materials, which exhibit not only high hydrothermal, thermal, and photochemical stability but also attractive structural features contributin…
The performance of organic photovoltaic devices based upon bulk heterojunction blends of donor and acceptor materials has been shown to be highly dependent on the thin film microstructure. In this tutorial review, we discuss the factors responsible for influencing blend microstructure and how these affect device perfo…
Well matched: Submicrometer-sized metal–organic framework (MOF) crystals (ZIF-90) were synthesized by a nonsolvent-induced crystallization technique and incorporated in mixed-matrix gas-separation membranes. ZIF-90/6FDA-DAM membranes (empty pink circle; beyond the upper bound for polymer membranes) show unprecedented…
