The document discusses two green chemistry instruments: 1) The Econoburette, which performs titrations using micro liters of substances, consuming less materials and time. It prevents hazardous fumes from entering the body. 2) The Survismeter, a single apparatus that measures viscosity, surface tension, and interfacial tension, replacing multiple instruments. It adheres to principles of reducing, reusing, and recycling materials while providing accurate results and inhibiting pollution. Both instruments provide safer, more efficient alternatives for chemistry laboratories.

XRD And XRF2.pptxDr. Rekha ram Choudhary

��

XRD and XRF are analytical techniques used to characterize materials. XRD determines the crystalline structure of materials by measuring diffraction patterns of X-rays. It can identify phases and minerals present in a sample. XRF determines the elemental composition of materials by detecting X-ray fluorescence emitted from a sample. Both techniques are non-destructive and provide qualitative and quantitative analysis of materials' composition and structure.

Superconductivityaninditabhattacharya27

��

The document summarizes key aspects of superconductivity. It describes how certain materials experience a loss of electrical resistance below a critical temperature. This critical temperature is known as the critical temperature (Tc). One of the earliest observations of superconductivity was by Kamerlingh Onnes in 1908 when he found mercury's resistivity suddenly dropped to zero at 4.2 K. The BCS theory provides a theoretical explanation for superconductivity involving electron pairing and lattice vibrations. Superconductors are categorized as either type-I or type-II, with the latter exhibiting higher critical magnetic fields and a mixed normal-superconducting state. Applications of superconductors include superconducting magnets used in MRI machines.

Gamma ray spectroscopyAryaReson

��

Gamma ray spectroscopy is a technique that uses gamma ray detectors to identify radioactive isotopes and nuclides in a sample. It works by measuring the energy of gamma rays emitted using detectors like scintillation or semiconductor detectors. The detector converts the gamma ray energy into electrical signals. A multichannel analyzer then measures and records the energy levels, producing a spectrum that reveals the gamma ray source by comparing energy levels to known radioactive isotopes. Gamma ray spectroscopy has applications in fields like nuclear physics, medicine, space exploration, and archaeology.

Colour removal by advnced methodsMAHAMMED RAFI

��

This document discusses various methods for removing color from textile effluents, which is an environmental concern. It covers physical methods like membrane filtration and adsorption. Chemical methods include coagulation and advanced oxidation processes, though they produce sludge. Biological methods like fungal and microbial degradation are most economical. Specifically, phytoremediation uses plants to uptake and degrade dyes, while photodegradation employs TiO2 and radiation like sunlight to break down dyes. Plant surface morphology impacts accumulation and different plant types may work best for specific dyes.

Successive radioactive decay and Radioactive Equilibrium: M ChoudharyDrMangilalChoudhary

��

The document discusses successive radioactive decay and radioactive equilibrium. It defines radioactive decay and types including alpha, beta, and gamma decay. It describes Rutherford-Soddy law where half of radioactive nuclei decay after each half-life. Successive decay occurs when daughter nuclei form that may also be radioactive. Radioactive equilibrium can be established depending on the relative decay constants of parent and daughter nuclei, and may be secular, transient, or not reached. Various cases are analyzed based on the parent nucleus lifetime compared to its daughter.

Quantum Mechanics by G. Aruldhas .pdfAshutosh Gaiha

��

This document discusses the development of a new type of battery that could revolutionize energy storage. It describes how the battery uses a solid electrolyte material that conducts ions quickly without using liquid electrolytes. This leads to a battery that charges faster, lasts longer, and poses less risk of fire than current lithium-ion batteries. The document concludes by stating that further research is still needed but that this new solid-state battery technology could enable many new applications if the remaining challenges can be overcome.

Gas chromatographyIlluri Shravani

��

Gas chromatography is an analytical technique used to separate and analyze volatile compounds. It works by distributing the sample between a stationary phase and a mobile gas phase. Key components of a gas chromatography system include the carrier gas, injector, column, and detector. The column allows separation of compounds based on differences in partitioning between the stationary and mobile phases. Detectors then provide a quantitative measurement of separated components. Common applications of gas chromatography include analysis of pharmaceuticals, foods, flavors, fragrances, and petrochemicals.

��

This document discusses different types of photodetectors. It describes photoconductive detectors like light dependent resistors (LDRs) and junction photodetectors including p-n photodiodes, PIN photodiodes, avalanche photodiodes, and Schottky photodiodes. PIN photodiodes are presented as an improvement over p-n photodiodes by having a larger depletion region for higher quantum efficiency. Avalanche photodiodes provide internal gain through impact ionization. Schottky photodiodes have a high speed due to being majority carrier devices. Phototransistors are also discussed as providing gain. Applications mentioned include fiber optics, cameras, medical devices, barcodes, and security systems

ION SELECTIVE POTENTIOMETRYArvind Singh Heer

��

This document summarizes different types of ion selective potentiometry electrodes, including liquid-liquid membrane electrodes, enzyme electrodes, and gas sensing electrodes. Liquid-liquid membrane electrodes use a water-immiscible liquid ion exchanger membrane to selectively measure ions like calcium. Enzyme electrodes immobilize enzymes like urease on an electrode to selectively measure enzyme substrates like urea. Gas sensing electrodes use a thin, porous, replaceable membrane to separate an analyte solution from an internal solution, allowing the electrode to selectively measure dissolved gases or ions by detecting pH changes.
