The FBISE was established under the FBISE Act 1975. [2] It is an autonomous body of working under the Ministry of Federal Education and Professional Training. [3] The official website of FBISE was launched on June 7, 2001, and was inaugurated by Mrs. Zobaida Jalal, the Minister for Education [4] The first-ever online result of FBISE was announced on 18 August 2001.

A past paper is an examination paper from a previous year or previous years, usually used either for exam practice or for tests such as University of Oxford, [1] [2] University of Cambridge [3] College Collections. Exam candidates find past papers valuable in test preparation.
A space-filling model of n-octane, the straight chain (normal) hydrocarbon composed of 8 carbons and 18 hydrogens, formulae: CH 3 CH 2 (CH 2) 4 CH 2 CH 3 or C 8 H 18.Note, the representative shown is of a single conformational "pose" of a population of molecules, which, because of low Gibbs energy barriers to rotation about its carbon-carbon bonds (giving the carbon "chain" great flexibility ...
Advanced Science is an interdisciplinary peer-reviewed open-access scientific journal covering fundamental and applied research in materials science, physics and chemistry, medical and life sciences, as well as engineering. It is published by Wiley-VCH and was established in 2014. The editor-in-chief is Kirsten Severing. [1]
RSC Advances is an online-only peer-reviewed scientific journal covering research on all aspects of the chemical sciences. It was established in 2011 and is published by the Royal Society of Chemistry. The current editor-in-chiefs are Russell Cox (Leibniz Universität Hannover) and Karen Faulds (University of Strathclyde). [1]
Advances in Chemical Physics is a peer-reviewed academic book series in the fields of chemical physics and related interdisciplinary fields (e.g. biophysics) published by John Wiley & Sons. The form of each publication is a book made of chapters, where all the chapters in a specific book are of a particular field.
Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.
Crystal structure of CH 3 NH 3 PbX 3 perovskites (X=I, Br and/or Cl). The methylammonium cation (CH 3 NH 3 +) is surrounded by PbX 6 octahedra. [13]The name "perovskite solar cell" is derived from the ABX 3 crystal structure of the absorber materials, referred to as perovskite structure, where A and B are cations and X is an anion.
