The porous carbon nanotubes were selectively prepared from the pristine carbon nanotubes. The surface of carbon nanotubes was firstly functionalized with Fe2O3 nanoparticles and subsequent heat treatment induced CNT etching. After removal of Fe2O3 nanoparticles, mesopores were formed in carbon ...

In this review, we describe recent progress made in the study of nanoparticles characterized by scanning tunneling microscopy (STM) and scanning tunneling spectroscopy (STS). Basic principles of STM measurements and single-electron tunneling phenomena through a single NP are summarized. We ...

In this work, ZnO/graphene (ZnO/GN) hybrid is successfully synthesized from graphene oxide (GO) and zinc hydroxide [Zn(OH)2)] by a facile freeze drying treatment and subsequent heat treatment method. The uniform ZnO nanoparticles (NPs) with a diameter less than 10 nm size were uniformly anchored ...

Platinum (Pt) nanoparticles with <4 nm diameter loaded on graphitic carbon nitride (g-C3N4) by reduction at 673 K behave as efficient co-catalysts for photocatalytic hydrogen evolution under visible light (λ

In this study, the catalytic activity of decatungstate (W10O324-) supported on mesoporous TiO2 assemblies (DT-MTA) was compared with that of homogeneous [Bu4N]4W10O32 catalysts under mild conditions. Our experiments showed that both catalytic systems achieve exceptionally high activity and ...

In the recent past there has been a growing interest in switchable surfactants and stimuli-responsive surface-active particles, since both have a surface activity which is either switchable or controllable and they can be recovered and re-used afterwards. Among various triggers the CO2/N2 trigger ...

In addition to chemical composition, particle concentration and size are among the main parameters used to characterize exposure to airborne ultrafine or nanoparticles. To assess occupational inhalation exposure, real-time instruments are recommended in the recent strategies published. Among ...

We describe a method for creating robust and stable core–shell polymer microspheres decorated with inorganic (IO) nanoparticles (NPs) by a self-organization process and heterocoagulation using a mussel-inspired polymer adhesive layer between the IO NPs and the microspheres.

Dimethylformamide (DMF) undergoes “double-reduction” to yield trimethylamine as a result of the concerted activation of DMF by two Si–H bonds (from different Si atoms) over Pt(0) nanoparticles as catalytic centers. Sterics on the Si atom govern the reaction and are also decisive for the structure ...

Organophosphorus (OP) compounds are the most widely used pesticides in agricultural field due to their high effectiveness for insects and diseases eradication but also cause widespread residues in food products and contamination of environment. Most of the OP compounds could not been detected by ...
