Nanoelectronics refer to the use of nanotechnology in electronic components. The term covers a diverse set of devices and materials, with the common characteristic that they are so small that inter-atomic interactions and quantum mechanical properties need to be studied extensively.
This is a complete basic and short guide about Nanotechnology i.e. what it means, what it will do, its applications, its uses, its future, disadvantages and almost everything. I make it little bit eye catchy and funnier by adding relative graphics and pictures so you can never get bored. At the end you found it 1000 times more interesting and funnier. Enjoy my work world.
Micromachined Electro-Mechanical Systems, also called microfabricated Systems, have evoked great interest in the scientific and engineering communities. This is primarily due to several substantive advantages that MEMS offer: orders of magnitude smaller size, better performance than other solutions, possibilities for batch fabrication and cost-effective integration with electronics, virtually zero dc power consumption and potentially large reduction in power consumption, etc.
This Seminar would give an introduction to these exciting developments and the technology and design approaches for the realization of these integrated systems. It would be followed with an introduction to the design of microsensors, such as the pressure sensor and the accelerometer, which began the MEMS revolution.
A systematic approach is developed to select manufacturing Process Chains for the generic elements of a MEMS device. A database of MEMS Process Chains and their attendant process attributes is developed from the existing literature, and used to construct Process Attribute charts. The performance requirements of MEMS beams and trenches are translated into the same set of Process Attributes. This allows for a screening of the Process Chains to obtain a list of candidate manufacturing methods.
I begin with a quick introduction to MEMS technology, micron scale and show that silicon is eminently suited for micromechanical devices and therefore the possibility of integrating MEMS with VLSI electronics. Smart cell phones and wireless enabled devices are poised to become commercial engines for the next generation of MEMS, since MEMS provide not only better functionality with smaller chip area, but also alternative transceiver architectures for improved functionality, performance and reliability.
The application domains cover microsensors and actuators for physical quantities, of which MEMS for automobile & consumer electronics forms a large segment; microfabricated subsystems for communications and computer systems.
بروتوكولات حكماء صهيون لغز من الألغاز في مجال البحث التاريخي، وهو اخطر كتاب ظهر في العالم ولا يستطيع أن يقدره إلا من يقرأ البروتوكولات ليستطيع أن يبصر الخطة التي رسمتها تيارات التاريخ لا سيما الحوادث الحاضرة وأصابع اليهود من ورائها. من هنا تبدو أهمية هذا الكتاب الذي يعرض فيه المؤلف لبروتوكولات حكماء صهيون، متعمقاً بجذور هذه البروتوكولات والقضايا الناتجة عنها بهدف إلقاء الضوء على خفاياها، وما أكثر خفاياها، حتى ليمس القارئ موضع الداء الصهيوني، ويرى حقيقته واضحة كوضوح الشمس على ضوء مجرى الوقائع والمعطيات التاريخية ليمكنه من استخلاص أبعاد الخطر الذي تشكله الصهيونية لا على العرب وحدهم ولكن على أمم الأرض.
لم يعرف العالم كتاباً أثار ضجة أكبر من الضجة التي أثارها كتاب "بروتوكولات حكماء صهيون" ولم تكن الآراء متناقضة في كتاب أكثر مما هي فيه. فقد اختلف الناس في حصتها، وأصلها، ودوافعها، وأهدافها... وليست دقة هذه الترجمة، ولا دقة المرحلة الحاضرة وحدها هي سبب نشر هذه الترجمة. بل يضاف إلى ذلك رأي خاص للمترجم فيها.
ومهما يكن الرأي فإن "البروتوكولات" جديرة بالقراءة، وجديرة بالتمعن، وجديرة بالحذر. مع التنبه دائماً إلى أن المغالاة في قوة العدو لا تختلف في نتائجها عن الاستهانة بها.

Nanoscience and nanotechnology are the study and application of extremely small things and can be used across all the other science fields, such as chemistry, biology, physics, materials science, and engineering.
It’s hard to imagine just how small nanotechnology is. One nanometer is a billionth of a meter, or 10-9 of a meter. Here are a few illustrative examples:
There are 25,400,000 nanometers in an inch
A sheet of newspaper is about 100,000 nanometers thick
On a comparative scale, if a marble were a nanometer, then one meter would be the size of the Earth
Nanoscience and nanotechnology involve the ability to see and to control individual atoms and molecules. Everything on Earth is made up of atoms—the food we eat, the clothes we wear, the buildings and houses we live in, and our own bodies.
But something as small as an atom is impossible to see with the naked eye. In fact, it’s impossible to see with the microscopes typically used in a high school science classes. The microscopes needed to see things at the nanoscale were invented relatively recently—about 30 years ago.
Once scientists had the right tools, such as the scanning tunneling microscope (STM) and the atomic force microscope (AFM), the age of nanotechnology was born.
Although modern nanoscience and nanotechnology are quite new, nanoscale materials were used for centuries. Alternate-sized gold and silver particles created colors in the stained glass windows of medieval churches hundreds of years ago. The artists back then just didn’t know that the process they used to create these beautiful works of art actually led to changes in the composition of the materials they were working with.
Today's scientists and engineers are finding a wide variety of ways to deliberately make materials at the nanoscale to take advantage of their enhanced properties such as higher strength, lighter weight, increased control of light spectrum, and greater chemical reactivity than their larger-scale counterparts.
