Results 1–10 of 23 for feri

fermentation → fermentacija

Fermentation is a class of biochemical reactions that break down complex organic molecules (such as carbohydrates) into simpler materials (such as ethanol, carbon dioxide, and water). Fermentation reactions are catalyzed by enzymes.

Fermi level → Fermijev nivo

Fermi level is the highest energy of occupied states in a solid at zero temperature. The Fermi level in conductors lies in the conduction band, in insulators it lies in the valence band, and in semiconductors it falls in the gap between the conduction band and the valence band. It was named after the Italian physicst Enrico Fermi (1901 - 1954).

fermion → fermioni

Fermion is any particle with spin equal to an odd multiple of 1/2. Fermion is a particle that obeys Fermi-Dirac statistics, e.g. electron, proton, neutron, muon, etc.

fermium → fermij

Fermium was discovered by Albert Ghiorso (USA) in 1953. Named in honour of Enrico Fermi. It is synthetic radioactive metal. Fermium was produced by bombarding lighter transuranium elements with still lighter particles or by neutron capture.

ferric → feri

Ferric is the term or prefix used to denote compounds of iron in which iron is in the trivalent, Fe(III), state, for example, ferric chloride, FeCl₃.

ferrous → fero

Ferrous is the term or prefix used to denote compounds of iron in which iron is in the divalent, Fe(II), state, for example, ferrous sulfate, FeSO₄.

potassium fertilizer → kalijevo gnojivo

Potassium fertilizers are compounds of potassium used as an artificial manure e.g. potassium-chloride, potassium-sulphate, potassium-magnesium-sulphate, and ashes formed after wood burns out.

ferrite → ferit

Ferrites are ceramic materials of the nominal formula MO·Fe₂O₃, where M is a divalent metal (Co, Mn, NI, or Zn). The ferrites show either ferrimagnetism or ferromagnetism, but are not electrical conductors, and they are used in high-frequency circuits as magnetic cores, in rectifiers on memory and record tapes, and various related uses in radio, television, radar, computers, and automatic control systems.

ferromagnetism → feromagnetizam

Ferromagnetism is a type of magnetism in which the magnetic moments of atoms in a solid are aligned within domains which can in turn be aligned with each other by a weak magnetic field. The total magnetic moment of a sample of the substance is the vector sum of the magnetic moments of the component domains. In an unmagnetized piece of ferromagnetic material the magnetic moments of the domains themselves are not aligned; when an external field is applied those domains that are aligned with the field increase in size at the expense of the others. Ferromagnetic materials can retain their magnetisation when the external field is removed, as long as the temperature is below a critical value, the Curie temperature. They are characterised by a large positive magnetic susceptibility.

actinides → aktinoidi

Actinides (actinons or actinoids) are the fourteen elements from thorium to lawrencium inclusive, which follow actinium in the periodic table. The position of actinium is somewhat equivocal and, although not itself an actinide, it is often included with them for comparative purpose. The series includes the following elements: thorium (Th), protactinium (Pa), uranium (U), neptunium (Np), plutonium (Pu), amercium (Am), curium (Cm), berkelium (Bk), californium (Cf), einsteinium (Es), fermium (Fm), mendelevium (Md), nobelium (No) and lawrencium (Lr). Every known isotope of the actinide elements is radioactive. Traces of Pa, Np and Pu are consequently found, but only Th and U occur naturally to any useful extent.
