Quantum Electrodynamics

Gravity remains the most elusive field. Its relationship with the electromagnetic field is poorly understood. Relativity and quantum mechanics describe the aforementioned fields, respectively. Bosons and fermions are often credited with responsibility for the interactions of force and matter. It is shown here that fermions factually determine the gravitational structure of the universe, while bosons are responsible for the three established and described forces. Underlying the relationships of the gravitational and electromagnetic fields is a symmetrical probability distribution of fermions and (...) bosons. Werner Heisenberg's assertion that the Schr\'f6dinger wave function and Heisenberg matrices do not describe one thing is confirmed. It is asserted that the conscious observation of Schr\'f6dinger's wave function never causes its collapse, but invariably produces the classical space described by the Heisenberg picture. As a result, the Heisenberg picture can be explained and substantiated only in terms of conscious observation of the Schr\'f6dinger wave function. Schr\'f6dinger\'92s picture is defined as information space, while Heisenberg\'92s picture is defined as classical space. B-theory postulates that although the Schr\'f6dinger picture and the Heisenberg picture are mathematically connected, the former is eternal while the latter is discrete, existing only as the sequence of discrete conscious moments. Inferences related to information-based congruence between physical and mental phenomena have long been discussed in the literature. Moreover, John Wheeler suggested that information is fundamental to the physics of the universe. However, there is a great deal of uncertainty about how the physical and the mental complement each other. Bishop Berkeley and Ernst Mach, to name two who have addressed the subject, simply reject the concept of the material world altogether. Professor Hardy defined physical reality as 'dubious and elusive'. It is proposed in this paper that physical reality, or physical instantiation in the classical space as described by Heisenberg picture is one thing with the consciousness. (shrink)

Supersymmetry (SUSY) has long been considered an exceptionally promising theory. A central role for the promise has been played by naturalness arguments. Yet, given the absence of experimental findings it is questionable whether the promise will ever be fulfilled. Here, I provide an analysis of the promises associated with SUSY, employing a concept of pursuitworthiness. A research program like SUSY is pursuitworthy if (1) it has the plausible potential to provide high epistemic gain and (2) that gain can be achieved (...) with manageable research efforts. Naturalness arguments have been employed to support both conditions (1) and (2). First, SUSY has been motivated by way of analogy: the proposed symmetry between fermions and bosons is supposed to 'protect' the small Higgs mass from large quantum corrections just as the electron mass is protected through the chiral symmetry. Thus, SUSY held the promise of solving a major problem of the Standard Model of particle physics. Second, naturalness arguments have been employed to indicate that such gain is achievable at relatively low cost: SUSY discoveries seemed to be well in reach of upcoming high-energy experiments. While the first part of the naturalness argument may have the right form to facilitate considerations of pursuitworthiness, the second part of the argument has been problematically overstated.

Incredibly fast charging occurs. Created to improve power execution (high-speed capability), they still depend on similar inherent breakpoints.

Nanoparticles can also be used as catalysts due to their high surface area. Of course, catalytic properties also occur in certain dimensions like magnetic properties. In other words, nanoparticles usually have catalytic properties if their specific surface is between 100 and 400 square meters per gram. Therefore, among nanoparticles with a specific volume, a nanoparticle with a larger surface area shows better catalytic properties. An example of nanoparticles that act as catalysts where various substances are placed on their surface and (...) chemical reactions are carried out. Apart from the mentioned cases, nanoparticles have many other applications in various medical industries (drug delivery, etc.), automobiles (anti-fogging windows, lightening the body, strengthening tires), electronics (making transistors), etc. The strength of carbon-carbon bonds gives carbon nanotubes amazing electronic properties. No previous material exhibits the extraordinary combination of mechanical, thermal and electronic properties attributed to them . However, their conductivity is what sets them apart. Multi-layered carbon nanotubes are the strongest materials that mankind has discovered so far in terms of electronic conductivity. The highest tensile strength or breaking strain for a carbon nanotube was up to 63 GPa, which is about 50 times more than the strongest conductors. Even the weakest types of multi-layered carbon nanotubes have multifold power in electronic conduction. These properties, along with the lightness of carbon nanotubes, give them great potential in applications such as aerospace. The electronic properties of the wall of carbon nanotubes are also extraordinary. It has high electrical conductivity (comparable to copper). It is particularly noteworthy that nanotubes can be metallic or semiconducting. The rolling action breaks the symmetry of the planar system and imposes a specific direction with respect to the hexagonal grid and the axial direction. Depending on the relationship between these axial directions and the unit vectors that describe the hexagonal lattice, nanotubes may behave electrically like metals or semiconductors , with some nanotubes having higher conductivity than copper, while Others behave more like silicon . And there are possibilities of making nano electronic devices from multi-layer nanotubes of CNTs. (shrink)

Note: Many types of nanosensors are designed using CP nanomaterials for nanobiological applications. (Conductive surface) The oxidation of conductive polymeric materials is easily altered by redox mechanisms, and the charge transfer properties of these materials are affected by structural parameters, such as diameter and dimensions. CP materials are able to provide sensitive and rapid responses to specific biological and chemical species. Techniques such as chemical polymerization are often used to make CP nanomaterials. Manufacturing strategies can be divided into three categories: (...) hard mold synthesis, soft mold synthesis, and mold-free synthesis. The most widely used conductive polymers in nanosensors are nanomaterials made from CP due to their unique chemical and electrical properties resulting from the properties of their pie-electron nanosystem. Many modeling and functionalization technologies are being developed to control the location, distribution, amount, or structure and orientation of biological nanomolecules at the nanomaterial level. Therefore, our level of contact between biological nanomolecules and nanomaterials is of particular importance in countless applications. Covalent and non-covalent modifications are two general methods for coupling biological molecules and CP nanomaterials. Covalent functionalization is a chemical process in which a strong bond or relationship between nanomaterials and biological molecules is formed. In many cases, surface chemical modifications are required to create active groups that can bind to biomolecules. Unlike covalent functionalization, in the non-covalent method, nanomolecules can be removed without destroying the geometric and electronic structure on the surface. Nanomaterials are formed. Conclusion : The large surface-to-volume ratio in nanostructures and the high potential for signal amplification provide ideal conditions for marking and detecting biological elements in the structure of nanosensors.

All electrochemical nano biosensors that have a molecular base depend on a very specific system to detect or track their target molecule. The importance of an electrochemical nanobiosensor is to provide a suitable support for connecting the target molecule to the probe and creating an electrical signal that can be measured and read.

The development of biosensors to measure the concentration of dissolved oxygen in the blood began. This sensor is also called COBD because it covers the surface of the electrode with an enzyme whose constituent is sometimes called (electro-calorie). Later, it helped oxidize glucose. This sensor was used to measure blood sugar. In the same Bapvshandn electrode, an enzyme that has the ability to convert urea into ammonium carbonate in the electrode material ++ ion, NH4, was used to create biosensors that (...) could measure the urea in the blood or urine. Each of these two early biosensors used a different transducer in its signal conversion section . In the first type, blood sugar was measured by measuring the electric current generated (ammetric),while in the urea sensor, the urea concentration was measured based on the electric charge created sensors are made (.Potentiometric) may someday the patient without having to visit a doctor and only on the basis of information that a COBD or Doctor-Board-on-Chip provides, the type of disease has been detected. And then injected into the blood. This will drastically reduce the dosage of the required drugs directly from the side effects of the Effect-Side drug , because the drug is very low and is also sent to the required place in the body. The drug acts directly on a biosensor that converts the biological response into an electrical signal and consists of two main components: the receptor and the detector. The ability to select one biosensor is determined by the receiving section. Enzymes, antibodies, and lipid layers are good examples of receptors. The task of the detector is to convert the physical or chemical changes by detecting the material to be analyzed into an obvious factor that the detectors can select in the type of reaction of the electrical signal. They do not have the perfect .They are electrochemical, optical, piezoelectric, and thermal. In the type of electrochemistry the action takes place in one of the following ways: amperometric, potentiometric, and impedance. The most common electrodes used in the potentiometric type include: the Glass electrode, the Selective-Ion ion electrode, and the FET sensitive-Ion ion field-effect transistor or ISFET. In general, a biosensor consists of an immobilized static biological system, such as a cell bundle, a micro enzyme, or an antibody, and a measuring. In the presence of a certain molecule, the biological system changes the properties of the environment. (shrink)

In general, in order to receive the electromagnetic wave in the space, the dimensions of the antenna must be in the order of the wavelength of the input to its surface.

It has been mathematically and theoretically proven that a quasi-metallic carbon nanotube can emit terahertz radiation when a time-varying voltage is applied to its sides. One of the most important parameters of any nano antenna is the current distribution on it.

Note: The field-effect tunnel transistor nMOS is an experimental type of transistor. Even if its structure is very similar to a metal-oxide semiconductor field-effect transistor nMOS , the basic switching mechanisms in these two transistors differ from each other; nMOS instead of exhibiting thermionic emission modulation, changes through a quantum tunnel modulation 12> They change through a dam. The field-effect tunneling transistor nMOS, as an alternative to conventional CMOS by enabling the voltage supply (VDD) with ultra-low power consumption, enables energy-efficient (...) computing during the sub-threshold slope (SS) range. This type of device has a reverse-bias gate structure, which is usually called a tunnel field-effect transistor nMOS. For low power applications, nMOS is considered. This device has less static leakage current than a MOSFET and is more resistant to SCEs. The most outstanding feature of nMOS is the capacity to produce a reverse subthreshold swing (SS) of less than the 60 mV/decade thermal limit (at 300 K), which is related to common reverse mode nMOSs. A pseudo-thermal SS is achievable because the drain current in nMOSs is generated by source-to-channel carrier injection, which is often under the band tunneling radius. It is placed in the quantum mechanical band (BTBT). Transistor speed nMOS is proportional to the current. The higher the current, the faster the transistor will be able to amplify and charge (the sequential capacitor voltage). For a given transistor speed and maximum acceptable subthreshold leakage, the subthreshold slope thus defines a minimum threshold voltage. Decreasing the threshold voltage is an essential part of the idea to scale the constant amount of nMOS to overcome some challenges associated with the nMOS structure, such as its need for ultra-sharp doping profiles; however, such devices may suffer from gate leakage due to the presence of large vertical fields in the nMOS transistor structure.

In general, nanoelectric supercapacitors can store large amounts of energy, but they tend to charge slowly and wear out quickly. Meanwhile, capacitors have a longer life and can be discharged quickly, but store much less total energy. In order to make nano supercapacitors, nanostructured arrays of electrostatic capacitors can be created.Electrostatic nanocapacitors are the simplest type of electronic energy storage device.

Nanoparticles are of great interest due to their wide application, both in industry and (...) in the natural sciences. While natural materials have constant physical properties regardless of size, the size of a nanoparticle determines its physical and chemical properties. Therefore, the properties of a material change as its size approaches the nanoscale and the percentage of atoms on the surface of the material becomes significant. The important feature of all nano structures is that in which the number of surface atoms is more than the number of volume atoms. This ratio increases with decreasing nanoparticle size.
