Bismuth selenide is a semiconductor and a thermoelectric material. [4] While stoichiometric bismuth selenide should be a semiconductor with a gap of 0.3 eV, naturally occurring selenium vacancies act as electron donors, so Bi 2 Se 3 is intrinsically n-type.
TOPSe is usually prepared by oxidation of trioctylphosphine with elemental selenium: P(C 8 H 17) 3 + Se → SeP(C 8 H 17) 3. Often the reaction is conducted without isolation of the TOPSe. [2] As a solution with trioctylphosphine oxide, TOPSe reacts with dimethylcadmium to give cadmium selenide.
Pinecone fishes are small and unusual marine fish of the family Monocentridae. The family contains just four species in two genera, one of which is monotypic. Their distribution is limited to tropical and subtropical waters of the Indo-Pacific. Pinecone fishes are popular subjects of public aquaria, but are both expensive and considered a ...
For this reason it is usually handled with air-free techniques. TOP reacts with elemental selenium to give trioctylphosphine selenide (TOPSe), which is a reagent for the preparation of cadmium selenide and related semiconductors.
The Quill and Quire called the illustrations in the book "inclusive" because of Princess Pinecone's mixed heritage and that the warriors in the story are in "all shapes, sizes, colours and ages." [9] Pinecone & Pony, an animated series based on the book produced by DreamWorks Animation Television was released on April 8, 2022, on Apple TV+. [10]
Web scraping is the process of automatically mining data or collecting information from the World Wide Web. It is a field with active developments sharing a common goal with the semantic web vision, an ambitious initiative that still requires breakthroughs in text processing, semantic understanding, artificial intelligence and human-computer interactions.
