sentences: A three-center two-electron bond is an electron-deficient chemical bond where three atoms share two electrons.
 The combination of three atomic orbitals form three molecular orbitals: one bonding, one "non"-bonding, and one "anti"-bonding.
 The two electrons go into the bonding orbital, resulting in a net bonding effect and constituting a chemical bond among all three atoms.
 In many common bonds of this type, the bonding orbital is shifted towards two of the three atoms instead of being spread equally among all three.
 Examples of 3c-2e bonds are the trihydrogen cation H3+ , and the dimeric structure of aluminium chloride.
Boron nitride nanosheet is a two-dimensional crystalline form of the hexagonal boron nitride (h-BN), which has a thickness of one to few atomic layers.
 It is similar in geometry to its all-carbon analog graphene, but has very different chemical and electronic properties – contrary to the black and highly conducting graphene, BN nanosheets are electrical insulators with a band gap of ~5.9 eV, and therefore appear white in color.
Lawrence Harding "Larry" Johnston (February 11, 1918 – December 4, 2011) was an American physicist, a young contributor to the Manhattan Project.
 He was the only man to witness all three atomic explosions in 1945: the Trinity nuclear test and the atomic bombing of Hiroshima and Nagasaki.
A Dry Forest are defined as a community of trees of different species that coexist in the same environment.
 These trees can grow nearby forming a canopy above.
 Dry forests lack an abundance of moisture, yet, there is an adequate amount of moisture to sustain the growth of the forest.
 Although dry forest tends to grow at an intermediate height compared to moist forest.
 Dry forest receives 850-1100mm of precipitation per year.
 High quantities of sea salt from the ocean decreases the height of the trees.
 Dry forest also consisted of layers of canopies, specifically two canopy layers that commonly found at an elevation below 300 meters.
 There is limited dead dry wood for termites to consume, this correlates with low density of termites in dry forests.
 The characteristics and development of Virgin Islands Dry Forest are contributed by a unique wind pattern that is usually strong.
 Dry Forest usually thrive in environments that have plenty sunshine, steep slopes, on soil that are challenged by thin rocky layers that poorly absorbs water.
 Within the three islands in the United States Virgin Islands, St. John has maintained a higher percentage of dry forest cover competing with St. Thomas at 43.1%; St. Croix has limited dry forest cover (9.22%).
 St. John and St. Thomas topography has significant steep hills and slopes compared to St. Croix.
 St. John is the most protected of the three islands, and as such it has the largest extensive tropical dry forests in the U.S. Virgin Islands.
 The island contains 650 native plants, 5,000 or more terrestrial insects, over 180 species of birds, of which 90% are native, and six native mammal bat species.
 One of the most common trees in the “native dry forest garden” is the amarat.
 They are acacias, (casha bush) but do not have thorns likes most other varieties.
Bilayer graphene is a material consisting of two layers of graphene.
 One of the first reports of bilayer graphene was in the seminal 2004 "Science" paper by Geim and colleagues, in which they described devices "which contained just one, two, or three atomic layers"
Andre Konstantin Geim, FRS, HonFRSC, HonFInstP (born 21 October 1958) is a Soviet-born Dutch-British physicist working in the School of Physics and Astronomy at the University of Manchester.
Antimony telluride is an inorganic compound with the chemical formula SbTe.
 It is a grey crystalline solid with layered structure.
 Layers consist of two atomic sheets of antimony and three atomic sheets of tellurium and are held together by weak van der Waals forces. SbTe is a narrow-gap semiconductor with a band gap 0.21 eV; it is also a topological insulator, and thus exhibits thickness-dependent physical properties.
C-value is the amount, in picograms, of DNA contained within a haploid nucleus (e.g. a gamete) or one half the amount in a diploid somatic cell of a eukaryotic organism.
 In some cases (notably among diploid organisms), the terms C-value and genome size are used interchangeably; however, in polyploids the C-value may represent two or more genomes contained within the same nucleus.
 Greilhuber "et al." have suggested some new layers of terminology and associated abbreviations to clarify this issue, but these somewhat complex additions are yet to be used by other authors.
Continuous stationery (UK) or continuous form paper (USA) is paper which is designed for use with dot-matrix and line printers with appropriate paper-feed mechanisms.
 Other names include "fan-fold paper", "sprocket-feed paper", "burst paper", "tractor-feed paper", and "pin-feed paper".
 It can be single-ply (usually woodfree uncoated paper) or multi-ply (either with carbon paper between the paper layers, or multiple layers of carbonless copy paper), often described as multipart stationery or forms.
 Continuous stationery is often used when the final print medium is less critical in terms of the appearance at the edges, and when continuously connected individual sheets are not inconvenient for the application.
 Individual sheets can be separated at the perforation (leaving a slight serration), and sheets also have edges with punched holes, which also can be removed at the perforation (one typical format).
White lined chipboard, also referred to as: WLC, GD, GT or UD, is a grade of paperboard typically made from layers of waste paper or recycled fibers. Most often it comes with two to three layers of coating on the top and one layer on the reverse side.
 Because of its recycled content it will be grey from the inside.
