Exempel på hur man kan använda ACICULAR i en mening

• It is a colorless to white mineral crystallizing in the monoclinic crystal system typically occurring as prismatic to acicular crystals or granular masses.
• The crystal lattice of aragonite differs from that of calcite, resulting in a different crystal shape, an orthorhombic crystal system with acicular crystal.
• Luxullianite (also known as luxulyanite or luxulianite) is a rare type of porphyritic granite, notable for the presence of clusters of radially-arranged acicular tourmaline crystals enclosed by phenocrysts of orthoclase and quartz in a matrix of quartz, tourmaline, alkali feldspar, brown mica, and cassiterite.
• It crystallizes in the monoclinic system and forms translucent bright blue acicular crystal clusters or drusey coatings.
• Scolecite, like natrolite and mesolite, usually occurs as acicular (needle-like) and fibrous aggregations.
• It crystallizes in the monoclinic system, usually as long prismatic crystals showing a diamond-shaped cross section, but also in fibrous, bladed, acicular, columnar, and radiating forms.
• It typically occurs as fibrous or powdery encrustations, but may also occur as acicular triclinic crystals.
• Minerals of the hollandite-cryptomelane and romanèchite groups also have fibrous or acicular habits and two perfect cleavages parallel to the fiber axis.
• Aragonite crystals are contrasted with those made of calcite (another variety of calcium carbonate) in that the latter tend to be stubby or dog-tooth-like ("rhombohedral", rather than acicular).
• In recent decades, barium ferrite has replaced acicular oxides; without any dopants, the acicular oxides produce very low coercivity values, making the material very magnetically soft, while barium ferrite's higher coercivity levels make the material magnetically hard and thus a superior choice for recording material applications.
• In geology, frostwork is a type of speleothem (cave formation) with acicular ("needle-like") growths almost always composed of aragonite (a polymorph of calcite) or calcite replaced aragonite.
• Antennae, head, thorax and abdomen dark brown, the antenna ringed narrowly with white; beneath: the palpi, thorax and abdomen snow-white, the third, slender acicular joint of the palpi conspicuously brown.
• Stems scandent, clambering or sprawling, branching, producing aerial roots, stiff, to 1-2(-5) m long, 2–3 cm thick; ribs 4–6 or more, later terete, acute; areoles 1,5–2 mm on Ø, reddish brown at first, later greyish brown, internodes 1,5-2,5 cm; spines 6–8, 1 mm long, acicular, white or yellowish, later blackish, radial spines 5–6 central spines 1–2, basally 0,25 mm in Ø above the swollen bases, apically attenuate-conical, circular in cross section, the bulbous bases 0,5 mm in Ø, hairlike spines none; epidermis light green, somewhat shining.
• conidia hyaline, acicular to obclavate, straight to mildly curved, indistinctly multiseptate, base truncate to long obconically truncate, tip subacute to subobtuse, 2–3.
• He identified this active principle as a substance composed of acicular, yellow, intergrown crystals that formed fluffy and light masses; and he mentioned that it could be used to destroy malignant tumors, to counteract toothaches, and as a revulsive.
• The dorsal layer, or tegmentum, is composed of one spherulitic sublayer, one crossed lamellar sublayer, and a ventral acicular sublayer.
• In steel it produces a bainite microstructure whereas in cast irons it produces a structure of acicular ferrite and high carbon, stabilized austenite known as ausferrite.
• 5–12 mm, basally ca 0,25 mm in diameter, acicular, elliptic or circular in cross section, bulbous basally, spreading, yellowish brown to brownish or yellow, grey in age, eventually deciduous hairs from lower part of areole ± numerous white or brownish, mature vegetative areoles usually lacking hairs, juvenile plants have spines shorter and fewer; epidermis glaucous green or bluish green, often ± purplish, smooth.
• Eventually Faden noticed that certain specimens had needle-like, acicular hairs along the midvein on the leaves' upper surfaces, while others had mainly or only hook-hairs.
• Close to this temperature it sublimes (changes directly from a solid to a vapor) and recrystallizes on cooler surfaces as minute acicular black crystals.
