LC Driving Point Functions | EduRev

The applications of copper (Cu) and Cu-based nanoparticles, which are based on the earth-abundant and inexpensive copper metal, have generated a great deal of interest in recent years, especially in the field of catalysis. The possible modification of the chemical and physical properties of these nanoparticles using different synthetic strategies and conditions and/or via postsynthetic chemical treatments has been largely responsible for the rapid growth of interest in these nanomaterials and their applications in catalysis. In addition, the design and development of novel support and/or multimetallic systems (e.g., alloys, etc.) has also made significant contributions to the field. In this comprehensive review, we report different synthetic approaches to Cu and Cu-based nanoparticles (metallic copper, copper oxides, and hybrid copper nanostructures) and copper nanoparticles immobilized into or supported on various support materials (SiO2, magnetic support materials, etc.), along with their applications in catalysis. The synthesis part discusses numerous preparative protocols for Cu and Cu-based nanoparticles, whereas the application sections describe their utility as catalysts, including electrocatalysis, photocatalysis, and gas-phase catalysis. We believe this critical appraisal will provide necessary background information to further advance the applications of Cu-based nanostructured materials in catalysis.

N2 - Synthesis techniques are given for any one element kind driving point function in two variables, s and x. Conditions for the realization of some two element kind driving point functions in s and x are also developed. Using active elements, any such function is shown to be realizable. Driving point functions in s and x with certain types of fixed (independent of x) and varying (dependent on x) real zeros and poles are shown to be realizable using only F-elements. Applications are presented.

Not every possible mathematical function for driving point impedance can be realised using real electrical components. Wilhelm (following on from R. M. Foster) did much of the early work on what mathematical functions could be realised and in which filter topologies. The ubiquitous ladder topology of filter design is named after Cauer.

There are a number of canonical forms of driving point impedance that can be used to express all (except the simplest) realisable impedances. The most well known ones are;

Mechanisms of Protein Synthesis by the Ribosome

Deeper analysis of the chart requires assessment and interpretive synthesis of planetary aspects, referring to recognized geometric relationships which are thought to describeor characterize the blending of planetary principles in personality. In some cases, groups of aspects are combined in a dynamic that is given greaterweight than would be accorded the individual aspects alone. For example, three (or more) planets may be in trine with each other, such that each is approximately 120º (±10º) fromthe others. This results in a dynamic called the Grand Trine, and it effectively magnifies the combined energies of all three points. A Kite Formation adds a fourth point to the Grand Trine; this fourth point, which may include one or more planets or astrological variables, is 60º from two points in the Grand Trine, and 180º from the third. A Kite Formation is illustrated below.

...admittance . This theorem represents one of the key results of classical electrical network synthesis, translated directly into mechanical terms. The first proof of a result of this type was given in =-=[4]-=-, which shows that any real-rational positive-real function could be realized as the driving-point impedance of an electrical network consisting of resistors, capacitors, inductors, and transformers. ...

Properties of driving point and transfer functions

A concise and highly enantioselective synthesis of colchicine (>99% ) in eight steps and 9.3% overall yield, without the need for protecting groups, was developed. A unique Wacker oxidation was used for enabling regioselective construction of the highly oxidized and synthetic challenging tropolone C-ring. Furthermore, asymmetric syntheses of β-lumicolchicine and -acetylcolchinol--methyl ether (NCME) were achieved. Notably, NCME was synthesized from β-lumicolchicine by an unusual decarbonylation and electrocyclic ring-opening cascade reaction.

The driving point impedance is a mathematical representation of the input impedance of a filter in the frequency domain using one of a number of notations such as Laplace transform (s-domain) or Fourier transform (jω-domain). Treating it as a one-port , the expression is expanded using continued fraction or partial fraction expansions. The resulting expansion is transformed into a network (usually a ladder network) of electrical elements. Taking an output from the end of this network, so realised, will transform it into a two-port network filter with the desired transfer function.
