Iodine Chemical element, symbol I and atomic number 53

Iodine is a chemical element with the symbol I and atomic number 53. The heaviest of the stable halogens, it exists as a semi-lustrous, non-metallic solid at standard conditions that melts to form a deep violet liquid at 114 degrees Celsius, and boils to a violet gas at 184 degrees Celsius. The element was discovered by the French chemist Bernard Courtois in 1811, and was named two years later by Joseph Louis Gay-Lussac, after the Greek Ιώδης "violet-coloured".

Tantalum Chemical element, symbol Ta and atomic number 73

Tantalum is a chemical element with the symbol Ta and atomic number 73. Previously known as tantalium, it is named after Tantalus, a villain from Greek mythology. Tantalum is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion-resistant. It is part of the refractory metals group, which are widely used as minor components in alloys.

Taif City in Makkah, Saudi Arabia

Taif is a city and governorate in the Makkah Province of Saudi Arabia. Located at an elevation of 1,879 m (6,165 ft) in the slopes of the Hejaz Mountains, which themselves are part of the Sarawat Mountains, the city has a 2020 estimated population of 688,693 people, making it the 6th most populous city in the kingdom.

Phenethylamine

Phenethylamine (PEA) is an organic compound, natural monoamine alkaloid, and trace amine, which acts as a central nervous system stimulant in humans. In the brain, phenethylamine regulates monoamine neurotransmission by binding to trace amine-associated receptor 1 (TAAR1) and inhibiting vesicular monoamine transporter 2 (VMAT2) in monoamine neurons. To a lesser extent, it also acts as a neurotransmitter in the human central nervous system. In mammals, phenethylamine is produced from the amino acid L-phenylalanine by the enzyme aromatic L-amino acid decarboxylase via enzymatic decarboxylation. In addition to its presence in mammals, phenethylamine is found in many other organisms and foods, such as chocolate, especially after microbial fermentation.

Tantalum carbide Chemical compound

Tantalum carbides (TaC) form a family of binary chemical compounds of tantalum and carbon with the empirical formula TaCx, where x usually varies between 0.4 and 1. They are extremely hard, brittle, refractory ceramic materials with metallic electrical conductivity. They appear as brown-gray powders, which are usually processed by sintering.

Tantalum(V) chloride Chemical compound

Tantalum(V) chloride, also known as tantalum pentachloride, is an inorganic compound with the formula TaCl5. It takes the form of a white powder and is commonly used as a starting material in tantalum chemistry. It readily hydrolyzes to form tantalum(V) oxychloride (TaOCl3) and eventually tantalum pentoxide (Ta2O5); this requires that it be synthesised and manipulated under anhydrous conditions, using air-free techniques.

Metal aromaticity is the concept of aromaticity, found in many organic compounds, extended to metals. The first experimental evidence for the existence of aromaticity in metals was found in aluminium cluster compounds of the type MAl
4
where M stands for lithium, sodium or copper. These anions can be generated in a helium gas by laser vaporization of an aluminium / lithium carbonate composite or a copper or sodium / aluminium alloy, separated and selected by mass spectrometry and analyzed by photoelectron spectroscopy. The evidence for aromaticity in these compounds is based on several considerations. Computational chemistry shows that these aluminium clusters consist of a tetranuclear Al2−
4
plane and a counterion at the apex of a square pyramid. The Al2−
4
unit is perfectly planar and is not perturbed the presence of the counterion or even the presence of two counterions in the neutral compound M

Al

. In addition its HOMO is calculated to be a doubly occupied delocalized pi system making it obey Hückel's rule. Finally a match exists between the calculated values and the experimental photoelectron values for the energy required to remove the first 4 valence electrons. The first fully metal aromatic compound was a cyclogallane with a Ga32- core discovered by Gregory Robinson in 1995.

Tantalum pentoxide Chemical compound

Tantalum pentoxide, also known as tantalum(V) oxide, is the inorganic compound with the formula Ta

Tantalum pentafluoride Chemical compound

Tantalum(V) fluoride is the inorganic compound with the formula TaF5. It is one of the principal molecular compounds of tantalum. Characteristic of some other pentafluorides, the compound is volatile but exists as an oligomer in the solid state.

Tantalum(V) bromide Chemical compound

Tantalum(V) bromide is the inorganic compound with the formula Taa2Br10. Its name comes from the compound's empirical formula, TaBr5. It is a diamagnetic, orange solid that hydrolyses readily. The compound adopts an edge-shared bioctahedral structure, which means that two TaBr5 units are joined by a pair of bromide bridges. There is no bond between the Ta centres.

Classified as a transition metal alkyl complex, hexamethyltungsten is an air-sensitive, red, crystalline solid at room temperature; however, it is extremely volatile and sublimes at −30 °C. Owing to its six methyl groups it is extremely soluble in petroleum, aromatic hydrocarbons, ethers, carbon disulfide, and carbon tetrachloride.

WAY-317538 (SEN-12333) is a drug that acts as a potent and selective full agonist for the α7 subtype of neural nicotinic acetylcholine receptors. It was not the most potent compound in the series, but was selected for further development on the basis of its high selectivity over related receptors, ease of synthesis, and good in vivo properties including high oral bioavailability and good brain penetration. It has nootropic and neuroprotective effects in animal studies, and is being investigated as a potential treatment for neurodegenerative and neurocognitive conditions including Alzheimer's disease and schizophrenia.

Abū al‐ʿUqūl Muḥammad ibn Aḥmad al‐Ṭabarī was a leading astronomer in Ta'izz and the first teacher of astronomy at the Muʾayyadiyya Madrasa. Of Iranian origin, he is known for compiling the largest single corpus of tables for astronomical timekeeping in a specific latitude during medieval times, with over 100,000 entries. Another interesting feature of his work was determining the latitude of Ta'izz as 13° 37'.
