E-Material, also called E Material, is a metal matrix composite consisting of beryllium matrix with beryllium oxide particles. It has high thermal conductivity (210-230 W/m K), and its thermal expansion can be adjusted to match other materials, e.g. silicon and gallium arsenide chips and various ceramics .
Electromaterials enable the transport of charged species (electrons and/or ions) as well as facilitate the exchange of charge to other materials.For atomic and molecule systems, this is observed as atomic electronic transition between discrete orbitals, while for bulk semiconductor materials electronic bands determine which transitions may occur.
PERURI is a State-Owned Enterprise (BUMN) that was established through Government Regulation Number 60 of 1971, [1] the result of a merger between the State Company (a.k.a PN) Pertjetakan Kebajoran (a.k.a Perkeba) which has a banknote printing business, with PN Arta Yasa which has a coin making business.

Gravure printing of electronic structures on paper. Printed electronics is a set of printing methods used to create electrical devices on various substrates. Printing typically uses common printing equipment suitable for defining patterns on material, such as screen printing, flexography, gravure, offset lithography, and inkjet.
In 2022, an increase of 3.4% was estimated of the generated e-waste globally, hitting 59.4Mt, which made the total unrecycled e-waste on earth to 2022 is over 347 Mt. [33] The transboundary flow of e-waste has gained attention from the public due to a number of worrisome headlines, but global study on the volumes and trading routes has not yet ...
A sampler is an electronic or digital musical instrument which uses sound recordings (or "samples") of real instrument sounds (e.g., a piano, violin or trumpet), excerpts from recorded songs (e.g., a five-second bass guitar riff from a funk song) or found sounds (e.g., sirens and ocean waves). The samples are loaded or recorded by the user or ...
Creatio ex nihilo is the doctrine that all matter was created out of nothing by God in an initial or a beginning moment where the cosmos came into existence. [13] [14] The third-century founder of Neoplatonism, Plotinus, argued that the cosmos was instead an emanation from God.
