The Nano Spray Dryer B-90 offers a new, simple, and alternative approach for the production of drug nanocrystals. Among attractive drugs, calpain inhibitor that inhibits programmed cell death 'apoptosis' is a candidate for curing apoptosis-mediated intractable diseases such as Alzheimer's disease and Parkinson's disease. In this study, the preparation of calpain inhibitor nanocrystals using Nan...
OBJECTIVE To discuss the influences of the concentrations of sodium cholate, cholesterol and drug, preparation temperature, ultrasonic time and power on the particle size and encapsulation efficiency of Flos Magnoliae volatile oil nano-liposome through film-ultrasonic wave technique together with membrane filter method. METHODS The nano-liposomes were prepared by film-ultrasonic wave techniqu...
Disclosed is a method of preparing pigmentary chromium oxide nano particles having 50 percent particle size less than about 100 nm. Preparation of nano chromium (III) oxide is investigated by thermal decomposition method. According to the disclosed method, a substantially dry solid composition of potassium dichromate and carbon active is heated in CO2 atmosphere to a temperature of about 60...
فاسیولازیس یک بیماری انگلی کبدی و از مهمترین آلودگی های انگلی در چهار پایان می باشد که بر اثر آلودگی با فاسیولا به وجود می آید و به یک بیماری حاد قابل توجه در انسان ها و حیوانات تبدیل شده است. فاسیولا از ترماتودهای مشترک بین انسان و دام می باشد. برآوردها نشان میدهد نزدیک به 180 میلیون انسان در دنیا در معرض ابتلا و 2.4 میلیون انسان در دنیا به این بیماری مبتلا هستند. ابتلا به این بیماری در مناطقی...
This work reports a facile sonochemical route in the synthesis of nano particle of deferasirox for the first time. One application of nanotechnology is in improvement of available treatments for various diseases. Deferasirox (ICL670 or Exjade) is a tridentate chelating agent for removing transfusion overload iron in thalassemia patients. In the present work, deferasirox was prepared in nano size...

In this paper, preparation method of unsymmetrical di-methyl hydrazine with nano aluminum particles (50 and 130 nm) has been investigated. One of the important aspects of the research is the uniform dispersion of the nano particles in the fuel gel. Homogeneity of the fuel influences the quality of propellant combustion. The results showed that the combination of ultrasonic-mechanical-magnetic a...
The Nano Spray Dryer B-90 offers a new, simple, and alternative approach for the production of drug nanocrystals. In this study, the preparation of steroid nanocrystals using the Nano Spray Dryer B-90 was demonstrated. The particle size was controlled by selecting the mesh aperture size. Submicrometer steroid particles in powder form were successfully obtained. These nanoparticles were confirme...
Dimensional measurements on nano-objects by atomic force microscopy (AFM) require samples of safely fixed and well individualized particles with a suitable surface-specific particle number on flat and clean substrates. Several known and proven particle preparation methods, i.e., membrane filtration, drying, rinsing, dip coating as well as electrostatic and thermal precipitation, were performed ...
BACKGROUND Many attempts have been performed and continued for improvement of dental amalgam properties during last decades. The aim of present research was fabrication and characterization of amalgam/titania nano composite and evaluation of its corrosion behavior. MATERIALS AND METHODS In this experimental research, nano particles of titania were added to initial amalgam alloy powder and the...
