Self-standing films were fabricated from butylamino-functionalized cellulose nanocrystals and tested for their mechanical strength and barrier performance.
Cu( ii ) ions in zeolites can be selectively converted to Cu( i ) ions at low temperatures using the strategy of vapor-induced reduction.
A new sulfide, SnGa2GeS6, has been synthesized, which represents the first member in the quaternary Sn/M/M'/Q (M = Ga, In; M' = Si, Ge; Q = S, Se, Te) system. It adopts a new structure type in the non-centrosymmetric space group Fdd2. In the structure, Sn(2+) is coordinated to a distorted square-pyramid of five S atom…
One of the engineering technologies that can be used to reduce air pollution is the use of catalytic converter mounted on vehicle gas exhaust duct. Unfortunately, these tools are very expensive in the market and not all motor vehicles use these technologis, because the catalyst was made from exoensive metals and rarel…
Novel polyimide aerogels with high absorption capacity and excellent recyclability for oils and organic liquids are fabricated by freeze-drying.
A Cu-tetrasulfonate-phthalocyanine was conjugated to cationic cellulose nanocrystals which serve as a heterogeneous based catalyst for aerobic oxidation of alcohols and alkyl arenes at room temperature in aqueous medium.
Herein, we employed first principle density functional periodic calculations to characterize the silicon counterpart of graphene:silicene. We found that silicene is far more reactive than graphene, very stable and strong Si-X bonds can be formed, where X = H, CH3, OH and F. The Si-F bond is the strongest one, with a b…
Until now most work on colloidal quantum dot-light-emitting diodes (QLEDs) has been focused on the improvement of the electroluminescent (EL) performance of monochromatic devices, and multi-colored white QLEDs comprising more than one type of QD emitter have been rarely investigated. To demonstrate a white EL as a res…
A novel BODIPY-porphyrin triad is prepared with two BODIPY molecules covalently attached via a 1,3,5-triazine molecule to a free-base carboxyphenyl meso -substituted porphyrin.
A route for producing diamond nanocrystals is reported in this paper. Li2CO3 containing carbon nanostructures synthesised in molten LiCl were transformed to nanodiamonds by simple heating at atmospheric pressure, far less severe conditions than conventional processes. The method presented offers the possibility of bul…
The perovskite polymorph of Mn(2)CrSbO(6) compound has been synthesized at 8 GPa and 1473 K. It crystallizes in the monoclinic P21/n space group with cell parameters a = 5.2180 (2) Å, b = 5.3710(2) Å, c = 7.5874(1) Å and β = 90.36(1)°. Magnetic susceptibility and magnetization measurements show the simultaneous antife…
The water resistance, flame retardancy and mechanical properties of POE intumescent flame-retardant systems were improved simultaneously.
The GQDs were exploited in bioimaging in vitro and in vivo : using the excitation-dependent PL, multi-color cell labeling was achieved and using long wavelength emission, the in vivo imaging was realized.
A one-step synthesis of Prussian blue nanoparticles possessing a concentration gradient of Gd3+ counterions, g-Gd-PB, has been developed, and the potential for the particles to perform as both MRI positive contrast agents and photothermal therapy agents is demonstrated. The synthesis of potassium/gadolinium ironhexacy…
We reported a synergy between Ru and Cu, obtaining a highly active catalyst for acetylene hydrochlorination, which improved the TOF of Cu to ca. 1.81 min −1 and showed that the Cu–Ru catalyst is an alternative to the toxic conventional HgCl 2 catalyst.
CNDs were immobilized on single-walled carbon nanotubes by wrapping the latter with poly(4-vinylbenzyl trimethylamine) (PVBTA), which features positively charged ammonium groups in the backbone. Negatively charged surface groups on the CNDs lead to attractive electrostatic interactions. Ground state interactions betwe…
A novel double-decker structural fluorinated POSS and a diphenol POSS were first synthesized for preparing a unique “cage–cage”-shaped hydrophobic fluoropolymer film with a low dielectric constant.
The use of nanocarriers such as liposomes to deliver anticancer drugs to tumors can significantly enhance the therapeutic index of otherwise unencapsulated cytotoxic agents. This is in part because of the fact that the phospholipid bilayer can protect healthy sensitive tissue from the damaging effects of these types o…
Real-time diagnosis and monitoring of disease development, and therapeutic responses to treatment, are possible by theranostic magnetic resonance imaging (MRI). Here we report the synthesis of a multifunctional liposome, which contains Gd-DOTA (an MRI probe), paclitaxel and c(RGDyk) (a targeted peptide). This nanopart…
Mesoporous high-surface-area silica (SiO 2 ) nanoparticles were produced from natural quartz sand (orthoquartzite) using three processing methods namely sol–gel, sonication, and spray pyrolysis.
