Surface Activity and Surface Active Agent

the study of bright and surface discrete cavity solitons dynamics in saturable nonlinear media

امروزه سالیتون ها بعنوان امواج جایگزیده ای که تحت شرایط خاص بدون تغییر شکل در محیط منتشر می-شوند، زمینه مطالعات گسترده ای در حوزه اپتیک غیرخطی هستند. در این راستا توجه به پدیده پراش گسسته، که بعنوان عامل پهن شدگی باریکه نوری در آرایه ای از موجبرهای جفت شده، ظاهر می گردد، ضروری است، زیرا سالیتون های گسسته از خنثی شدن پراش گسسته در این سیستم ها بوسیله عوامل غیرخطی بوجود می آیند. گسستگی سیستم عامل...

Surfactants - Surface Active Agents

The definition for a detergent is a cleaning agent. The main cleaning agent used in earlier days was soap. This term means a compound formed from the reaction of a fatty acid with a base such as caustic soda, forming the sodium soap of the acid. The more commonly used cleaning agent in this day and age is the synthetic detergent (SYNDET) which is a formulation such as TIDE or FAB. The essential...

Segmentation of cortical surface and interior brain structures using active surface / active volume templates

Advanced applications such as neurosurgical planning and simulation require both surface and interior anatomical information in order to be truly effective. We are developing a segmentation scheme based on collections of active surface templates embedded within an active volume. This composite system encodes high-level anatomical knowledge of both cortical surface and interior brain structures ...

A Universal Surface Modification Protocol for Active Surface Catalytic Microdevices

A universal surface modification for glass and fused silica microchannels has been developed. The method allows for the formation of catalytic surfaces within a channel after channel closure. These surfaces can contain ligand systems or functionalities of choice covalently attached to the robust surface modification. The utility of the system is demonstrated by the formation of Jacobsen and Gla...
