Up until now there has been no direct method for detecting the electronic and magnetic structure of each atomic layer at the surface, which is an essential analysis technique for nanotechnology. For this purpose, we have developed a new method, diffraction spectroscopy, based on the photon energy dependence of the angular distribution of Auger electron emission. We have applied this method to a...

The synergistic combination of layer-by-layer (LbL) assembly and nanoporous membrane templating has greatly facilitated the creation of complex and functional nanotubular structures. The approach takes advantage of both the new properties conferred by assembling diverse LbL building blocks and the tight dimensional control offered by nanotemplating to enable new functionalities that arise from ...

in this study, in order to constitute polyelectrolyte multilayers (pem) using layer-by-layer nanotechnology, recycled fibers were subsequently treated with cationic starch (cs) and anionic starch (as) multi-layers each layer conducted at neutral ph for 10 minutes. also, to compare with mechanical of refining, the pulp was refined for 25 minutes to the freeness of about 291 ml.csf using valley b...

Nowadays nanotechnology as a new direction of science allows us to develop therapeutic methods of the endogenous intoxication syndrome and to create a new class of biocompatible sorbents. In Ukraine first preparations of medical nanotechnology were produced and patented in 1998. These are IKBB (intracorporeal biocorrector), magnet-controlled sorbent (MCS-B), and Micromage-B. The preparations ar...

Crystalline bacterial cell surface layers (S-layers) are monomolecular arrays of (glyco)proteins that have recently produced a wealth of new opportunities in nanotechnology. Whereas the in vitro imaging of isolated S-layers is well established, their direct imaging on live cells remains very challenging. Here we use atomic force microscopy (AFM) to visualize S-layer nanoarrays on living Coryneb...

The existence of things is directly related to their structural symmetry in a broad framework ranging from atoms crystalline materials and simple cells complex organisms like humans. However, imbalance that occurs through natural or artificial means can provide completely different advantages. Molecules, crystals, structures with constitute the family Janus-type materials. This perspective prov...

the 21st century nanotechnology has the potential to make a huge impact on sustainability; but to achieve this potential, nanotechnology is all about getting more function on less space. in other hand, nanotechnology is one of the most extremely important components in sustainable development. it has the potential to reduce the environmental impact and energy intensity of structures, as well as...

Graphene is turning out to be the material that will effectively kick-start a new era for nanotechnology. The impressive properties of this atom-thick carbon layer are taking shape and form with early reports of successful applications based on it. The turning point for this material will be its low-cost mass production. In this report a chemist's perspective on the production methods for graph...
