Some credit unions are turning to next-generation information security solutions such as Terbium
Labs' Matchlight comprehensive, dark web data monitoring system to mitigate the hazards.

Hybrid vehicles combining a gasoline engine and electric motor have become increasingly popular in many countries, but sourcing a steady supply of rare earth elements such as dysprosium and terbium
has been a challenge.
Terfenol-D is an alloy composed of terbium
, dysprosium and iron developed by the Naval Ordnance Laboratory in 1971.
Dysprosium prices have climbed 3 percent from the previous month to $265 per kilogram, while prices of terbium
, a phosphor raw material, have increased 11 percent to around $570 per kilogram.
For these assays the donor fluorophore (terbium
) on the receptor causes energy transfer to the acceptor fluorophore (Fluormone Green) on the bound ligand, resulting in emission at 520 nM.
Michael Moore, chief technology officer and co-founder of the Baltimore, Maryland-based data security firm Terbium
Labs, noted that police have managed to take down online criminals even without bypassing encryption.
Rare earths are 17 chemical elements in the periodic table, specifically 15 lanthanides: lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium
, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, as well as scandium and yttrium.
For the first time, the possibility of substitution of calcium (Ca), magnesium (Mg) and yttrium (Y), respectively, to neodymium (Nd), terbium
(Tb) and holmium (Ho), was presented in the carbonate reef sediments of the Kok-Dumalak oil and gas-bearing field (Uzbekistan) , and later in the REE spectra of high molecular weight compounds (HMWC) of the produced and residual oils of different regions (West Siberia, Bashkortostan, Tatarstan, Kazakhstan, and Uzbekistan) Figure 1.
, neodymium, yttrium, praseodymium, europium will remain scarce in the long run for the major developed countries.
Other rare earths--like europium, terbium
, and yttrium--glow.
ions have unique fluorescent properties when complexed with organic ligands.
