This paper presents the synthesis of complex nanostructures of the Fe3O4-n[SiO1.5 γ-(CH2)3(NH2)](NH2)n δ- (GL)n ε type [Fe3O4 = magnetic core; n[SiO1.5 γ-(CH2)3(NH2)] = coated layer; (NH2)n δ,-NH2= surface and deep amino groups which play an important role in biochemical interfacing; (GL)n ε= exterior superficial glutaraldehyde layer]. These nanostructures have several interesting physical and chemical characteristics, such as: biochemical

As a result of the global climatic changes generated by the alteration of the environment through polution, the ecosystems’ natural ressources are incontrollably distributed, generating unforseeable effects at the level of the subsequent evolution of the natural balance factors. One of the greatest challenges of the science concerned with environment protection, is that of real time monitoring of the biochemical constitution. The real time monitoring

The obtaining of intelligent materials requires strict control of physical and chemical parameters that characterize them. In most cases, especially in the case of the nano- or microcomposite structures, the parameters to be controlled and quantified are of morphological and topological nature. This is a direct consequence of the fact that the chemical and physical properties of the nanoparticles and composite materials are strongly dependent on

The present paper presents the fixing mechanisms of microorganisms on support carrying agents based on Fe3O4 biochemically activated nanoparticles. The processing of biological fixing carrying agents with undifferentiated action is utterly important because it enlarges the type and the number of the fixed biological structures with a view to subsequent separation and identification.The biological fixing carrying agents based on nanoparticles having

A new approach of the foliar nutritive fluids formulation as emulsions and their properties design was grounded on the last illuminations in the mechanism and kinetics of the foliar nutrition. Emulsified organic and inorganic phases are bearing extended multifunctional biological activities - nutrition, growth enhancing and fungi repelling. Selection of the overbasic potassium salts of naphthenic and oleic acids as organic phase carrier entrusted

New chiral enantiopure ureas and thioureas with (R,R)-TADDOL backbone were synthesized. Bis-(thio)ureas with C2 symmetry were obtained from TADDOL iso(thio)cyanates and bifunctional amino-(thio)ureas from TADDAMINE, respectively. These were tested for carboxylate recognition capacity and the association constant was determined for the most stable complex.
