Despite much research into and development within the complex area of the initial wet web strength of paper, no complete model has yet been developed to describe this property. This type of paper strength is the most important property to ensure an effective paper machine run. Furthermore, the process of strength deve…
An azole-based metal–organic framework [Cd(tzphtpy) 2 ] n ·6.5 n H 2 O, hydrothermally synthesized from the reaction mixture of a π-electron rich azole ligand 4-(tetrazol-5-yl)phenyl-2,2′:6′,2″-terpyridine (Htzphtpy) and CdBr 2 ·4H 2 O, displays direct white-light emissions at a wide range of excitation wavelengths (2…
CONTEXT: Combination anticancer therapy is promising to generate synergistic anticancer effects, to maximize the treatment effect and to overcome multi-drug resistance. Nanostructured lipid carriers (NLCs), composed of solid and liquid lipids, and surfactants are potentially good colloidal drug carriers. OBJECTIVE: Th…
Graphene oxide (GO) has attracted huge interest in the area of biomedical application due to its unique physicochemical properties, but the issue of long-term toxicity in the body remains unclear. Here, the rationally designed GO nanocarriers (ssPEG-PEI-GO) modified with polyethylene glycol (PEG) and branched polyethy…
The clay mineralogy of pyroclastic Nb(Ta)-Zr(Hf)-REE-Ga mineralization in Late Permian coal-bearing strata from eastern Yunnan Province; southwest China was investigated in this study. Samples from XW and LK drill holes in this area were analyzed using XRD (X-ray diffraction) and SEM (scanning electronic microscope).…
The present work reviews current research activities for possible applications of silicon carbide (SiC) nanostructures. The main attention is devoted to emerging biomedical applications which can bring a boon for a healthy society. Highlights toward the widespread of SiC nanostructures in new fields of applications ar…
The synthesis, X-ray crystal structure, and photophysical properties of unsubstituted hexabenzo[ a , c , fg , j , l , op ]tetracene are described. Unlike the previously reported tert -butyl-substituted analogues, unsubstituted hexabenzo[ a , c , fg , j , l , op ]tetracene showed a helically twisted conformation in the…
From atoms to molecules and bio-macromolecules, from organelles to cells, tissues, to the whole living system, nature shows us that the formation of complex systems with emergent properties originates from the hierarchical self-assembly of single components in guided bottom-up processes. By using DNA as a fundamental…
Carbon nanotubes (CNTs) filled with iron sulfide nanoparticles (NPs) are prepared by inserting sulfur and ferrocene into the hollow core of CNTs followed by heat treatment. It is found that pyrrhotite-11T iron sulfide (Fe-S) NPs with an average size of ≈15 nm are encapsulated in the tubular cavity of the CNTs (Fe-S@CN…
Cardiovascular protein therapeutics such as neuregulin (NRG1) and acidic-fibroblast growth factor (FGF1) requires new formulation strategies that allow for sustained bioavailability of the drug in the infarcted myocardium. However, there is no FDA-approved injectable protein delivery platform due to translational conc…
Thiol–epoxy–acrylate hybrid polymer networks (HPNs) are formed by the combination of nucleophilic thiol–acrylate Michael addition and thiol–epoxy coupling reactions catalyzed by 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) in a one-pot synthesis. A stoichiometric balance between thiol groups (multifunctional thiols with a…
High fatigue resistance, bistability, and drastic property changes among isomers allow efficient modulation of the current output of organic thin-film transistors (OTFTs) to be obtained by a photogating of the charge-injection mechanism.
We report on a plasticized polyurethane ionophore-based thin film material (of hundreds of nanometer thickness) for simultaneous voltammetric multianalyte ion activity detection triggered by the oxidation/reduction of an underlying poly(3-octylthiophene) film. This material provides excellent mechanical, physical, and…
In this study, a novel multi-walled carbon nanotubes reinforced nanocrystalline copper matrix composite with super high strength and moderate plasticity was synthesized. We successfully overcome the agglomeration problem of the carbon nanotubes and the grain growth problem of the nanocrystalline copper matrix by combi…
Smart RFID label with a printed multisensor platform for environmental monitoring, Quintero, A Vásquez, Molina-Lopez, F, Smits, E C P, Danesh, E, van den Brand, J, Persaud, K, Oprea, A, Barsan, N, Weimar, U, de Rooij, N F, Briand, D
Key to the widespread application of smart polymers in drug delivery is understanding the mechanistic interplay, as well as consequence, of the presence of these macromolecules within living systems.
Microporous metal‐organic frameworks (MOFs) based on phosphonic ligands are still a very small family of materials if compared to carboxylate‐based MOFs, due to some inherent features that make them challenging to synthesize and to characterize. Nonetheless, metal phosphonates display remarkable chemical and thermal r…
Many efforts have focused on the sequestration and immobilization of 99 Tc because the radionuclide is highly mobile in oxidizing environments and presents serious health risks due to its radiotoxicity and long half-life ( t 1/2 = 213 000 a). One of the more common methods for Tc removal from solution and immobilizati…
The most recent release of the open source and general purpose Geant4 Monte Carlo simulation toolkit (Geant4 10.2 release) contains a new set of physics models in the Geant4-DNA extension for improving the modelling of low-energy electron transport in liquid water (<10 keV). This includes updated electron cross sectio…
