On the path to functional graphene electronics, suitable templates for chemical vapor deposition (CVD) growth of high -mobility graphene are of great interest. Among various substrates, hexagonal boron nitride (h-BN) has established itself as one of the mo ...
We investigated a suspended bilayer graphene where the bottom/top layer is doped by boron/nitrogen substitutional atoms. By using density functional theory calculations, we found that at high dopant concentration (one B-N pair every 32 C atoms), the electr ...
The electrochemical polymerization of diphenylamine (DPA) onto electrodes of Pt coated with highly separated metallic (98%) or semiconducting (99%) single-walled carbon nanotubes (SWCNTs) in the presence of H3PW12O40 was performed by cyclic voltammetry in ...
Gammarids were exposed to sediments from a deposition site located on the Rhone River (France) downstream of a fluoropolymer manufacturing plant. Gammarids accumulated to various extents four long-chain perfluoroalkyl carboxylic acids (PFCAs) from C-9 to C ...
Pt3Ni alloy supported by carbon nanofibers (CNs) composites (Pt3Ni/CNs) synthesized by a simple solvothermal process was introduced into dye-sensitized solar cells (DSCs) as counter electrode (CE) for the first time, and the DSCs based on Pt3Ni/CNs CE obta ...
Atom vacancies are intrinsic defects of carbon nanotubes. Using a zigzag nanotube as reference, this paper focuses on the comparison of calculations performed within density functional theory and a number of classical force fields widely used for carbon sy ...
Grafting carbon nanotubes (CNTs) directly on carbon fibers represents a promising approach in order to strengthen the weak interface between carbon fibers and polymer matrix in carbon fiber reinforced polymer composites (CFRCs). We have carried out direct ...
Single-nanocrystal and ensemble photoluminescence measurements on CuInS2 semiconductor nanocrystals reveal luminescence bandshapes that are broad compared to those typical of individual II–VI or related semiconductor nanocrystals. This finding is consisten ...
• A new Zn(II) phthalocyanine (Pc) based low bandgap HTM is introduced for perovskite solar cells. Steady state and time-resolved photoluminescence (PL) measurements indicated an evenly matched hole extn. efficiency between sym-HTPcH and spiro-OMeTAD. On a ...
From their discovery, CNTs have increasingly attracted interest because of their peculiar electrical, mechanical, and chemical properties. In 1991, Sumio Iijima first observed and described in detail the atomic arrangement of this new type of carbon struct ...
