ACTIVATED CARBON FIBER - THE HYBRID OF CARBON FIBER AND ACTIVATED CARBON
From application perspectives in adsorption, activated carbon fiber (ACF) is by far one of the most important carbon nanoporous materials to be considered. It has great advantages over other commercial porous storage materials. Activated carbon fiber (ACF) is a promising microporous material with a fiber shape and wel…
Biochars in soils: new insights and emerging research needs
The quantity, quality and breadth of research connected to biochar have grown rapidly since 2009/2010 when a number of books and reviews were published, some with policy support (Lehmann & Joseph, 2009; Shepherd, 2009; Sohi et al., 2009; Verheijen et al., 2010), and a European Commission biochar event was held at the…
A biomimetic hyperbranched poly(amino ester)-based nanocomposite as a tunable bone adhesive for sternal closure
A novel mussel-inspired adhesive can bond well to the surface of wet bone and be programmed to set in a suitable manner for sternal closure applications. With good wet adhesion properties, low exothermic properties, biodegradability and low toxicity, we believe that this technology, which can be further built upon and…
Reduction of 4-nitrophenol catalyzed by silver nanoparticles supported on polymer micelles and vesicles
We report the reduction of 4-nitrophenol catalyzed by silver nanoparticles supported on polymer micelles and vesicles which can significantly improve the stability, dispersibility and catalytic activity of silver nanoparticles even at one ppm.
High alkalinity boosts visible light driven H 2 evolution activity of g-C 3 N 4 in aqueous methanol
A high rate of 2.23 mmol h(-1) g(-1) (quantum efficiency of 6.67% at 400 nm) for visible light driven photocatalytic H2 evolution can be achieved with g-C3N4 by alkalization of the solution to a pH of 13.3, due to accelerated transfer of photoholes to the sacrificial donor.
Enhanced photocatalytic H 2 evolution over micro-SiC by coupling with CdS under visible light irradiation
Fine-tuning surface activation of the micro-SiC catalyst via hybridizing a suitable amount of CdS to obtain effective surface active sites.
Hydroisomerization of long-chain paraffins over nano-sized bimetallic Pt–Pd/H-beta catalysts
The hydroisomerization of long-chain n -paraffins was studied in the temperature range of 205–230 °C at p H2 = 50 bar over bimetallic catalysts consisting of mixtures of platinum and palladium supported on commercially available nano-sized zeolite beta.
Effect of support on selectivity and on-stream stability of surface VOx species in non-oxidative propane dehydrogenation
Al2O3, SiO2(MCM-41), and Al2O3–SiO2 (Siral®) with a SiO2 content varying from 1 to 70 wt.% were used to prepare supported catalysts with a V loading below one monolayer. Their activity, selectivity and on-stream stability were tested in non-oxidative propane dehydrogenation (DH) at 550 °C. The highest space–time yield…
A cascade reaction based fluorescent probe for rapid and selective fluoride ion detection
A cascade reaction-based colorimetric and fluorescent probe for selective fluoride ion detection is reported. The probe displays a fast response (t1/2 = 2.41 min) and 550-fold fluorescence enhancement during sensing of fluoride ions. Application of the probe in live cell imaging is demonstrated.
Rapid prototyping of chitosan-coated alginate scaffolds through the use of a 3D fiber deposition technique
Three dimensional, periodic scaffolds of chitosan-coated alginate are fabricated in a layer-by-layer fashion by rapid prototyping. A novel dispensing system based on two coaxial needles delivers simultaneously alginate and calcium chloride solutions permitting the direct deposition of alginate fibers according to any…
Tin Sensitization for Electroless Plating Review
Tin sensitization prior to electroless plating improves deposition of metals on a variety of substrates. This review summarizes relevant characteristics of the tin sensitized substrates, pre-treatment of surfaces before tin sensitization, adhesion, one- and two-step tin sensitization processes, photo-selective metal d…
Electrocatalytic activity for the oxygen reduction reaction of oxygen-containing nanocarbon synthesized by solution plasma
Oxygen-containing nanocarbon materials were successfully synthesized from a mixed solvent of benzene (BZ) and 1,4-dioxane (DO) by solution plasma. TEM observation demonstrated that the synthesized carbons had a diameter in the nanoscale range, their size increased with an increase in the DO content. XRD and Raman spec…
Fine structural features of nanoscale zero-valent iron characterized by spherical aberration corrected scanning transmission electron microscopy (Cs-STEM)
An angstrom-resolution physical model of nanoscale zero-valent iron (nZVI) is generated with a combination of spherical aberration corrected scanning transmission electron microscopy (Cs-STEM), selected area electron diffraction (SAED), energy-dispersive X-ray spectroscopy (EDS) and electron energy-loss spectroscopy (…
Zinc oxide microrods and nanorods: different antibacterial activity and their mode of action against Gram-positive bacteria
ZnO micro and nanorods, produced through simple and inexpensive techniques, resulted to be strong antimicrobials against Gram-positive bacteria, in vitro as well as in vivo , by altering cell outer structures like membrane and exopolysaccharides.

"bright" contrast in the hepatic vasculature. More importantly, this new class of ultrafine sub-5 nm iron oxide nanoparticles showed much faster body clearance than those with larger sizes, promising better safety for clinical applications.
An Overview: Recent Development of Titanium Oxide Nanotubes as Photocatalyst for Dye Degradation
Today, organic dyes are one of the largest groups of pollutants release into environment especially from textile industry. It is highly toxic and hazardous to the living organism; thus, the removal of these dyes prior to discharge into the environment is essential. Varieties of techniques have been employed to degrade…
Guest control of structure in porous organic cages
Two porous organic cages with different thermodynamic polymorphs were induced by co-solvents to interchange their crystal packing modes, thus achieving guest-mediated control over solid-state porosity. In situ crystallography allows the effect of the co-solvent guests on these structural interconversions to be underst…
