Hydrogen peroxide (H2O2) is well-known oxidizing, bleaching agent and also one of the significant by-products of diverse regulating biological processes. It has been recognized as a threat in the progression of atherosclerosis, renal disease, ageing and other diseases. Hence, determination of H2O2 in trace levels in biological samples is of great importance. This article briefly reviews the ele...

Since their discovery, carbon nanotubes (CNTs) have been eminent members of the nanomaterial family. Because of their unique physical, chemical and mechanical properties, they are regarded as new potential materials to bring enormous benefits in cell biology studies. Undoubtedly, the first step to prove the advantages of CNTs is to understand the basic behavior of CNTs inside the cells. In a nu...

Nanodiamond powder belongs to the carbon nanomaterial family, which, along with graphene, fullerene and nanotubes, has attracted great interest in recent years due to its unique physical and chemical properties. Initially, nanodiamond applications were rooted in the defense industry but have now reached into a variety of fields, such as fine polishing, lubricating, coatings and polymers. Curren...

A continuum mechanics theory is established for the in-surface buckling of one-dimensional nanomaterials on compliant substrates, such as silicon nanowires on elastomeric substrates observed in experiments. Simple analytical expressions are obtained for the buckling wavelength, amplitude and critical buckling strain in terms of the bending and tension stiffness of the nanomaterial and the subst...

PN junctions in nanoscale materials are of interest for a range of technologies including photodetectors, solar cells and light-emitting diodes. However, Schottky barriers at the interface between metal contacts and the nanomaterial are often unavoidable. The effect of metalsemiconductor interfaces on the behavior of nanoscale diodes must be understood, both to extract the characteristics of th...
