    STRONG AND WEAK INTERLAYER INTERACTIONS OF TWO-DIMENSIONAL MATERIALS AND THEIR ASSEMBLIES Tyler William Farnsworth A dissertation submitted to the faculty at the University of North Carolina at Chapel Hill in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Department of Chemistry. Chapel Hill 2018 Approved by: Scott C. Warren James F. Cahoon Wei You Joanna M. Atkin Matthew K. Brennaman © 2018 Tyler William Farnsworth ALL RIGHTS RESERVED ii ABSTRACT Tyler William Farnsworth: Strong and weak interlayer interactions of two-dimensional materials and their assemblies (Under the direction of Scott C. Warren) The ability to control the properties of a macroscopic material through systematic modification of its component parts is a central theme in materials science. This concept is exemplified by the assembly of quantum dots into 3D solids, but the application of similar design principles to other quantum-confined systems, namely 2D materials, remains largely unexplored. Here I demonstrate that solution-processed 2D semiconductors retain their quantum-confined properties even when assembled into electrically conductive, thick films. Structural investigations show how this behavior is caused by turbostratic disorder and interlayer adsorbates, which weaken interlayer interactions and allow access to a quantum- confined but electronically coupled state. I generalize these findings to use a variety of 2D building blocks to create electrically conductive 3D solids with virtually any band gap. I next introduce a strategy for discovering new 2D materials. Previous efforts to identify novel 2D materials were limited to van der Waals layered materials, but I demonstrate that layered crystals with strong interlayer interactions can be exfoliated into few-layer or monolayer materials.
  • A Specific Gravity Index for Minerats

    A Specific Gravity Index for Minerats

    A SPECIFICGRAVITY INDEX FOR MINERATS c. A. MURSKyI ern R. M. THOMPSON, Un'fuersityof Bri.ti,sh Col,umb,in,Voncouver, Canad,a This work was undertaken in order to provide a practical, and as far as possible,a complete list of specific gravities of minerals. An accurate speciflc cravity determination can usually be made quickly and this information when combined with other physical properties commonly leads to rapid mineral identification. Early complete but now outdated specific gravity lists are those of Miers given in his mineralogy textbook (1902),and Spencer(M,i,n. Mag.,2!, pp. 382-865,I}ZZ). A more recent list by Hurlbut (Dana's Manuatr of M,i,neral,ogy,LgE2) is incomplete and others are limited to rock forming minerals,Trdger (Tabel,l,enntr-optischen Best'i,mmungd,er geste,i,nsb.ildend,en M,ineral,e, 1952) and Morey (Encycto- ped,iaof Cherni,cal,Technol,ogy, Vol. 12, 19b4). In his mineral identification tables, smith (rd,entifi,cati,onand. qual,itatioe cherai,cal,anal,ys'i,s of mineral,s,second edition, New york, 19bB) groups minerals on the basis of specificgravity but in each of the twelve groups the minerals are listed in order of decreasinghardness. The present work should not be regarded as an index of all known minerals as the specificgravities of many minerals are unknown or known only approximately and are omitted from the current list. The list, in order of increasing specific gravity, includes all minerals without regard to other physical properties or to chemical composition. The designation I or II after the name indicates that the mineral falls in the classesof minerals describedin Dana Systemof M'ineralogyEdition 7, volume I (Native elements, sulphides, oxides, etc.) or II (Halides, carbonates, etc.) (L944 and 1951).

    L`x1//7Lhmdq`knesgdLnmsg9@c`lhsd Our specimens of this month’s mineral were collected in Mexico at one of the richest and most historically significant of all colonial-era silver mines—the 410-year-old Ojuela Mine, which ranks high among the top-ten specimen localities in the world. OGXRHB@K OQNODQSHDR Chemistry: Zn2(AsO4)(OH) Basic Zinc Arsenate (Zinc Arsenate Hydroxide), often containing some copper Class: Phosphates, Arsenates, and Vanadates Subclass: Basic Phosphates, Arsenates, and Vanadates Group: Olivenite Crystal System: Orthorhombic Crystal Habits: Usually prismatic or horizontally elongated; often as drusy crusts, aggregates, and radiating clusters in wheel-like and wheat-sheaf forms; occasionally botryoidal with a textured surface of crystal terminations. Color: Light-yellow, honey-yellow, brownish-yellow; pale-green to greenish-blue with increasing copper content; occasionally purple with manganese content or pink with cobalt content; rarely white or colorless. Luster: Adamantine to vitreous Transparency: Transparent to translucent Streak: White to pale green Cleavage: Good in one direction, poor in a second. Fracture: Uneven to subconchoidal, brittle. Hardness: 3.5-3.6 Specific Gravity: 4.3-4.5 Luminescence: Often fluoresces a brilliant yellow-green. Figure 1. Ideal Refractive Index: 1.710-1.768 adamite crystal, typical of Ojuela. Distinctive Features & Tests: Best field marks are color; crystal habit; exclusive occurrence in oxidized, arsenic-rich zinc deposits; high specific gravity; and brilliant, yellow-green fluorescence. Can be confused with smithsonite [ZnCO3], which does not fluoresce. Dana Classification Number: 41.6.6.3 M @L D Adamite, correctly pronounced “ADD-ahm-ite,” is named for the French mineralogist Gilbert-Joseph Adam (1795-1881).
