“…In this work, the models of formic acid-oxygen fuel elements have been tested on the basis of carbon nanotube composite electrodes with platinum-palladium particles. The membrane-electrode assemble consisted of a polymer membrane Nafion-115 pressed at a temperature of 85°C [35] between the composite anode and cathode based on reduced graphene oxide. Pt-Pd nanoparticles when metal loading (m s ) was of 0.8-1.3 mg/cm 2 on rGO-Nafion served as anode, rGO-Nafion with Pt nanoparticles when metal loading (m s ) was 0.5 mg/cm 2 served as cathode, the process temperature was 25°C.…”

In the present experimental work new polymer-reduced graphene oxide (rGO) nanocomposites with bimetallic platinum-palladium nanoparticles as functional electrodes for chemical power sources were prepared. The size and shape of nanoparticles in the composites have been studied by use of atomic force and high-resolution transmission electron microscopy techniques, X-ray phase analysis and small-angle X-ray scattering. Model tests on the basis of chemically-obtained composite electrodes under operating conditions of fuel elements with formic acid oxidation were carried out.

“…Nanotubes integrated within a nanocomposite made of CHI nanofibres, and apatite nanocrystals exhibited improved surface hydrophilicity, osteoblast adhesion and proliferation in vitro [59]. Recently, a renewed interest has been developed upon the carbon mono-layered graphene and its variants (graphene oxide, GO) [60] due to its good biocompatibility [61] but also its possible uses as biosensors [55,[62][63][64]. Graphene can be used in different forms (monolayer nanoplatelets, nanoribbons, nanotubes) and can easily be integrated within the cells showing excellent capacity as drug delivery carrier [65,66].…”

In the last decade, regenerative medicine has benefited from the exponential development of nanomaterial sciences, tissue engineering and cell-based therapies. More and more sophisticated designed structures and surface topologies are being developed to basically mimic the extracellular matrix of native tissues such as cartilage and bone. Here we give an overview of the progress made in osteochondral lesion repair, with nano-engineered scaffolds comprising building blocks such as nanoparticles, nanotubes, layer-by-layer nano-assemblies, molecular self-assembly, nanopatterned surfaces…. This nano-engineering technology is coupled with bio-functionalization, by the use of adhesion peptides, growth factors, or deoxyribonucleic acid, to drive cell adhesion, proliferation and behavior towards tissue regeneration. In osteochondral regeneration, the challenge is the simultaneous development of chondrocytes and cartilage extracellular matrix on the one side and a well vascularized bone tissue with osteoblasts on the other side. g y

“…By applying some oxidative treatment, it is possible to longitudinally unzip MWCNTs and to obtain graphene sheets with the appropriate number of layers. 1 By controlling the process of the MWCNTs unzipping, it is also possible to obtain the MWCNTs with a defective structure 2,3 or so called disordered MWCNTs. 4 The electronic properties of MWCNTs with an armchair structure were found to depend on the degree of unzipping.…”

Photoluminescent graphene quantum dots (GQDs) the one- or two-layer graphene nanoparticles 1.5–3 nm in size with a blue emission have been obtained from electrochemically synthesized partially unzipped multi-walled carbon nanotubes ultrasonically treated for one hour. Various physicochemical methods including photoluminescence spectroscopy, XRD, TEM, and Raman spectroscopy, have been used to characterize the electrochemically synthesized partially unzipped multi-walled carbon nanotubes and GQDs. Two-layer oxygen electrodes were fabricated, where GQDs served as an active layer. The investigations of electrocatalytic characteristics of the oxygen electrodes fabricated of the obtained materials were carried out in a fuel half-cell with an alkaline electrolyte. The fabricated oxygen electrodes were stable for six months at a discharge current density of 200 mA cm−2. The obtained GQDs are promising materials as a new type of catalyst carriers for oxygen electrodes of fuel cells.
