ممكن لا هنتواااااااااا ... أسماء جامعات كندا اللي تعطي ماستر نانو..

أخوي راجع مواضيع الأخ الفاضل "نانو 2020" فمواضيعه ثرية ومباشرة في تخصص النانو في كندا ...

موفق خير يالغالي ...

ثاااااااااااانكيووووووووو... بس انا بنوتة أخوي ههههههههه

وش علاقة النانو بالكيمياء ؟؟؟

اذكرة قريب من الفيزياء

ههههههههههه ياحليلك يالفيزيائية ....
النانو هو اساسا تعامل مع الذرات في كل مجالات النانو ... والذرات ياعمري بنات مين برايك؟؟؟؟؟
كيمياء ولا فيزياء ههههههههههههههههههه
الله يهديك بس...
مشكورة اختي

ياليت احد يفيدنا في اسرع وقــــــــــــــــــــــــت
لان عندي نفس الاستفسارات

بإختصار ... النانو هو علم الذرات والجزيئات المتناهية في الصغر (مقاسا) ومن هنا أتخذ مسمى نانو Nano بمعنى متناهي الصغر ... وعلاقته تكاد تكون مع جميع العلوم والتطبيقات الهندسة المعروفة ... مثل الكيمياء والفيزياء والأحياء والطب مرورا بالهندسة الكيميائة والميكانيكية والنووية والكهربائية والمعدات والتقنية الخاصة بالطب والصحة عموما والأدوية كذلك ...

وهذا موضوع الأخ العزيز نانو ... وهو مهم في هذا الجانب:

Nanotechnology
The University of Waterloo offers the first MASc and PhD programs in Nanotechnology of its kind in Canada. The interdisciplinary research program, jointly offered by three departments in the Faculty of Science and four in the Faculty of Engineering, provide students with a stimulating educational environment that spans from basic research through to application. The goal of the collaborative program is to allow students to gain perspectives on nanotechnology from a wide community of scholars within and outside their disciplines in both course and thesis work.
The MASc collaborative program provides a strong foundation in the emerging areas of nano-engineering in preparation for the workforce or for further graduate study and research leading to a doctoral degree. Four key areas of research strengths have been identified: nanomaterials, nano-electronics design and fabrication, nano-instruments and devices, and nano-biosystems. The objective of the PhD program is to prepare students for careers in academia, industrial R & D and government research labs.

http://en.wikipedia.org/wiki/Nanotechnology
Nanotechnology, shortened to "nanotech", is the study of the controling of matter on an atomic and molecular scale. Generally nanotechnology deals with structures of the size 100 nanometers or smaller in at least one dimension, and involves developing materials or devices within that size. Nanotechnology is very diverse, ranging from extensions of conventional device physics to completely new approaches based upon molecular self-assembly, from developing new materials with dimensions on the nanoscale to investigating whether we can directly control matter on the atomic scale.
There has been much debate on the future implications of nanotechnology. Nanotechnology has the potential to create many new materials and devices with a vast range of applications, such as in medicine, electronics and energy production. On the other hand, nanotechnology raises many of the same issues as with any introduction of new technology, including concerns about the toxicity and environmental impact of nanomaterials,[1] and their potential effects on global economics, as well as speculation about various doomsday scenarios. These concerns have led to a debate among advocacy groups and governments on whether special regulation of nanotechnology is warranted.

Nanomaterials




This includes subfields which develop or study materials having unique properties arising from their nanoscale dimensions.[13]

• Interface and Colloid Science has given rise to many materials which may be useful in nanotechnology, such as carbon nanotubes and other fullerenes, and various nanoparticles and nanorods.
• Nanoscale materials can also be used for bulk applications; most present commercial applications of nanotechnology are of this flavor.
• Progress has been made in using these materials for medical applications; see Nanomedicine.
• Nanoscale materials are sometimes used in solar cells which combats the cost of traditional Silicon solar cells
• Development of applications incorporating semiconductor nanoparticles to be used in the next generation of products, such as display technology, lighting, solar cells and biological imaging; see Quantum Dots.

[edit] Bottom-up approaches





These seek to arrange smaller components into more complex assemblies.

• DNA nanotechnology utilizes the specificity of Watson–Crick basepairing to construct well-defined structures out of DNA and other nucleic acids.
• Approaches from the field of "classical" chemical synthesis also aim at designing molecules with well-defined shape (e.g. bis-peptides[14]).
• More generally, molecular self-assembly seeks to use concepts of supramolecular chemistry, and molecular recognition in particular, to cause single-molecule components to automatically arrange themselves into some useful conformation.

[edit] Top-down approaches





These seek to create smaller devices by using larger ones to direct their assembly.

• Many technologies that descended from conventional solid-state silicon methods for fabricating microprocessors are now capable of creating features smaller than 100 nm, falling under the definition of nanotechnology. Giant magnetoresistance-based hard drives already on the market fit this description,[15] as do atomic layer deposition (ALD) techniques. Peter Grünberg and Albert Fert received the Nobel Prize in Physics for their discovery of Giant magnetoresistance and contributions to the field of spintronics in 2007.[16]

• Solid-state techniques can also be used to create devices known as nanoelectromechanical systems or NEMS, which are related to microelectromechanical systems or MEMS.
• Atomic force microscope tips can be used as a nanoscale "write head" to deposit a chemical upon a surface in a desired pattern in a process called dip pen nanolithography. This fits into the larger subfield of nanolithography.
• Focused ion beams can directly remove material, or even deposit material when suitable pre-cursor gasses are applied at the same time. For example, this technique is used routinely to create sub-100 nm sections of material for analysis in Transmission electron microscopy.

[edit] Functional approaches





These seek to develop components of a desired functionality without regard to how they might be assembled.

• Molecular electronics seeks to develop molecules with useful electronic properties. These could then be used as single-molecule components in a nanoelectronic device.[17] For an example see rotaxane.
• Synthetic chemical methods can also be used to create what forensics call synthetic molecular motors, such as in a so-called nanocar.

[edit] Biomaterials


Silica sand on the Classic Caribbean beach on the island of Martinique - Les Salines


Biomineralization (e.g. silicification) is quite common in the biological world and occurs in bacteria, single-celled organisms, plants (e.g. petrified wood), and animals (invertebrates and vertebrates). Crystalline minerals formed in this type of environment often show exceptional mechanical properties (e.g. strength, hardness, fracture toughness) and tend to form hierarchical structures that exhibit microstructural order over a range of length or spatial scales. The minerals are typically crystallized from an environment that is undersaturated with respect to certain metallic elements such as silicon, calcium and phosphorous, which are readily oxidized under conditions of neutral pH and low temperature (0 - 40 degrees C). Formation of the mineral may occur either within or outside of the cell wall of an organism, and specific biochemical reactions for mineral deposition exist that include lipids, proteins and carbohydrates. The significance of the cellular machinery cannot be overemphasized, and it is with advances in experimental techniques in cellular biology and the capacity to mimic the biological environment that significant progress is currently being reported.
