Several months later further operations in the quarry exposed another large triphylite crystal that had been partly reworked hydro- thermally into a granular aggregate composed of residual triphylite, siderite, qu.attz,apatite, plagioclase,ludlamite and abundant columnar- fibrous massesof a dark clove-brown mineral. The latter mineral was f ound by the writer to afiord an n-ray powder pattern identical with that of triploidite, but with smaller cell dimensions, and the indices of refrac- tion proved to be considerably higher than those of the Branchville triploidite. These facts, together with the occurrence of the mineral as an alteration product of triphylite, rather than of lithiophilite as at Branchville, suggestedthat the material was the iron analogue of trip- loidite.

STRONG and WEAK INTERLAYER INTERACTIONS of TWO-DIMENSIONAL MATERIALS and THEIR ASSEMBLIES Tyler William Farnsworth a Dissertati
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 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).

Diamond Dan's Mineral Names Dictionary
A Dictionary of Mineral Names By Darryl Powell Mineral Names What do they mean? Who created them? What can I learn from them? This mineral diction‐ ary is unique because it is illustrated, both with mineral drawings as well as pictures of people and places after which some minerals are named. The people pictured on this page have all made a con‐ tribution to what is formally called “mineral nomenclature.” Keep reading and you will discover who they are and what they did. In 1995, Diamond Dan Publications pub‐ lished its first full book, “A Mineral Collector’s Guide to Common Mineral Names: Their Ori‐ gins & Meanings.” Now it is twenty years later. What you will discover in this issue and in the March issue is a re‐ vised and improved version of this book. This Mineral Names Dictionary contains mineral names that the average mineral collector will encounter while collecting minerals, attending shows and visiting museum displays. In addition to the most common min‐ eral names, there are some unofficial names which you will still find on labels. Each mineral name has a story to tell or a lesson to teach. If you wanted to take the time, each name could become a topic to study. Armalcolite, for example, could quickly be‐ come a study of a mineral, first discovered on the moon, and brought back to earth by the astronauts Armstrong, Aldrin and Collins (do you see parts of their names in this mineral name?) This could lead you to a study of American astronauts landing on the moon, what it took to get there and what we discovered by landing on the moon.
