Benzo[4,5]thieno[2,3-b]pyridine (BTP) was newly developed as an electron deficient moiety for high triplet energy materials and two BTP derivatives with the BTP and carbazole groups were synthesized as high triplet energy bipolar host materials. The BTP derivatives were effective as the host materials for green and bl…
Organic photovoltaics (OPVs) are a topic of extensive research because of their potential application in solar cells. Recent work has led to the development of a coarse-grained model for studying poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) blends using molecular simulations. Her…
A series of ferrocenyl substituted pyrazaboles were prepared, which have an electron-withdrawing pyrazabole moiety as the central core, with a D-π-A-π-D structural motif (D = donor, A = acceptor) and containing a variety of π bridges. A crystallographic study reveals that the pyrazabole central core was observed in pl…
Spherical silica nanoparticles of various particle sizes (~10 to 100 nm), produced by a modified Stoeber method employing amino acids as catalysts, are investigated using Dynamic Nuclear Polarization (DNP) enhanced Nuclear Magnetic Resonance (NMR) spectroscopy. This study includes ultra-sensitive detection of surface-…
A facile and sensitive enzyme-free sandwich-type immunosensor for the detection of carbohydrate antigen 125 (CA125) was designed based on Au@Pd core–shell nanoparticles. Au@Pd nanoparticles were used both as electrode-modifying materials to immobilize the primary antibody (Ab1) of CA125 and as labels of secondary anti…
Zirconium oxide (ZrO2) has been nominated as a radiopacifying agent for use in MTA-like Portland cement-based root-filling materials. This research examines the impact of 20 wt% ZrO2 nanoparticles in the size range 50 to 75 nm on the early hydration chemistry of white Portland cement. Nano-ZrO2 was found to accelerate…
A new photo-cross-linkable poly(acrylic acid) (PAA) polymer functionalized with a photoreactive benzophenone group (PAA-BP) was synthesized and examined as a binder for Si-based anodes. Upon UV irradiation, the PAA-BP binders formed an irreversible cross-linked structure through the formation of a new three-dimensiona…
Graphene has been widely introduced into photocatalysis to enhance photocatalytic performance due to its unique physical and chemical properties. However, the effect of graphene on the surface chemical reactions of photocatalysis has not been clearly researched, which is important for photocatalysis because photocatal…
A favorable Si (core)-hollow carbon nanofiber (sheath) nanocomposite, was synthesized by a coaxial electrospinning technique. As a potential anode material for LIBs, this composite displays a high reversible capacity of 1300 mA h g(-1) even after 80 cycles at 0.5 C. It also exhibits a reversible discharge capacity as…
A new type of nonstoichiometric rutile titanium dioxide (TiO2) film with around 15 at% oxygen vacancies homogeneously distributed throughout the bulk was prepared. The resultant films, when used as a photoelectrode, showed a photoelectrochemical water splitting activity 1.7 times that of stoichiometric TiO2 at a bias…
This review focuses on MRI contrast agents for tumor diagnosis. Several types of low molecular weight Gd3+-based complexes and dextran-coated superparamagnetic iron oxide (SPIO) nanoparticles have been used for clinical tumor diagnosis as longitudinal relaxation time (T1) and transverse relaxation time (T2) MRI contra…
Inverse lyotropic liquid crystal phases comprising spatially-limited aqueous nanodomains have potentially wide-ranging applications, including the encapsulation and selective delivery of small molecules and as aqueous nanoreactors for molecular catalysis. We report the aqueous self-assembly of two homologous, zwitteri…
Reduced graphene oxide (rGO) has been engineered with a hybrid of dispersed Ag and ZnO nanoparticles by a one-step hydrothermal technique using graphene oxide, AgNO3 and Zn(CH3COO)2 precursors without adding any external toxic reagent. Formation of the Ag–ZnO–rGO hybrid is confirmed from X-ray diffractometry, high res…
Since introduction to the clinics in the 1990s, resorbable osteosynthesis systems have undergone extensive improvements in order to establish their use as a standard treatment, especially in craniomaxillofacial surgery. However, the development of osteosynthesis systems made of poly(α-hydroxy acid) polymers has been h…
Magnetic resonance imaging (MRI) is at the forefront of non-invasive medical imaging techniques. It provides good spatial and temporal resolution that can be further improved by the use of contrast agents (CAs), providing a valuable tool for diagnostic purposes. Ultrasmall superparamagnetic iron oxide (USPIO) nanopart…
The AlN solubility product in liquid iron containing manganese up to 22 mass% were measured by the metal-nitride-gas equilibration technique in the temperature range from 1823 to 1873 K. Manganese significantly increased the AlN solubility product in liquid iron primarily due to the large effect of manganese on the ni…
A new type of polycrystalline sintered diamond has been successfully synthesized by direct conversion from highly oriented pyrolytic graphite at 15 GPa and 2300°C. It is optically transparent and consists entirely of layered nanocrystals (50–100 nm thick) of cubic diamond, which are tightly bound to each other and hav…
For the first time, pseudopolyrotaxane prodrug micelles with high drug content were prepared in water, which could be used for cancer therapy. It is anticipated that this facile strategy may open a novel avenue for the development of multifunctional drug delivery systems.
A class of multifunctional hybrid nanoparticles (NPs) that can integrate a magnetic core, silver (Ag) nanocrystals, and a biocompatible poly(ethylene glycol) (PEG) shell were synthesized and characterized and their applications as antibacterial agents, optical labels for cellular imaging and drug carriers were tested.…
Metal-containing zeolites, especially Sn-Beta, perform as very efficient heterogeneous catalysts in the selective oxidation of levoglucosenone, which is considered as a platform chemical for the production of highly-valuable chemicals, towards the synthesis of the optically pure γ-lactone (S)-γ-hydroxymethyl-α,β-buten…
