CHEMISTRY GLOSSARY
crystal water → kristalna voda
Crystal water is water contained in certain salt crystals. It can be removed by heating. Crystals that contain crystal water are called hydrated and their salts hydrates.
base-centered orthorhombic lattice → bazno centrirana ortorompska rešetka
Base-centered or side-centered or end-centered monoclinic lattice (orthorhombic-C), like all lattices, has lattice points at the eight corners of the unit cell plus additional points at the centers of two parallel sides of the unit cell. It has unit cell vectors a≠b≠c and interaxial angles α=β=γ=90°.
body-centered orthorhombic lattice → prostorno centrirana ortorompska rešetka
Body-centered orthorhombic lattice (orthorhombic-I), like all lattices, has lattice points at the eight corners of the unit cell plus an additional points at the center of the cell. It has unit cell vectors a≠b≠c and interaxial angles α=β=γ=90°.
ideal crystal → idealni kristal
Ideal crystal is a single crystal with a perfectly regular lattice that contains no impurities, imperfections, or other defects.
isotropic crystal → izotropni kristal
The measured properties of an isotropic crystal are independent of the axis of testing. Opposite of anisotropic.
face-centered orthorhombic lattice → plošno centrirana ortorompska rešetka
Face-centered orthorhombic lattice (orthorhombic-F), like all lattices, has lattice points at the eight corners of the unit cell plus additional points at the centers of each face of the unit cell. It has unit cell vectors a≠b≠c and interaxial angles α=β=γ=90°.
liquid crystal → tekući kristal
Liquid crystals or crystalline liquids are a physical state between crystals and melts. The liquid crystalline phase - the so-called mesophase - is formed at the melting point. The most important (usable) mesophases are nematic, cholesteric and smectic phase, having different molecular orientations.
perfect crystal → savršeni kristal
Perfect crystal is a crystal with no defects or impurities made of completely identical repeating subunits. Further, a perfect crystal has only one possible arrangement of subunits, with every subunit making exactly the same contribution to the total energy of the crystal.
simple orthorhombic lattice → jednostavna ortorompska rešetka
Simple or primitive orthorhombic lattice (orthorhombic-P) has one lattice point at the each corner of the unit cell. It has unit cell vectors a≠b≠c and interaxial angles α=β=γ=90°.
Bravais lattice → Bravaisova rešetka
Bravais lattice is a set of points constructed by translating a single point in discrete steps by a set of basis vectors. The French crystallographer Auguste Bravais (1811-1863) established that in three-dimensional space only fourteen different lattices may be constructed. All crystalline materials recognised till now fit in one of these arrangements. The fourteen three-dimensional lattices, classified by crystal system, are shown to the bottom.
