At the start of this editorial, thanks are extended once again to Malcolm Southwood, whose software tools for managing the workflow have made the changeover trouble-free. A big thank you also to contributors, editorial board members and referees,whoseconscientiousworkhasmadethiseditionpossible.JohnChapman’sexcellentimages are scattered through several articles, communicating far more than words ever could and Peter Briscoe’s understated colour palette has brought a new level of professionalism to the location maps. Volume 22 owes a great deal to our new typesetter, Robert Preston, who has relieved Frank Ince of some of the responsibilities of Journal Manager. Itistraditionalforneweditorstobeginwithanentreatytoreaderstoconsiderwritinganarticle.Thisis simply a request to share knowledge and enthusiasm. The more inexperienced (or cavalier) may go on to claim that the process is straightforward and painless. Not so! An article will absorb a certain quantumoftimeandeffort.Authorsoftenfindthat‘thedoing’makesitworthwhile(althoughthismay only be evident in retrospect). An article at least ensures that information is placed on permanent record. In these less-than-certain times, look around and ask yourself: are collections and their associated data safe? The nuts and bolts of the writing process are described in an updated Guide for Authors, which is available on the Society website. It explains the content and structure of articles and the minutiae of grammar and style, but is not recommended as a starting point. The Guide is detailed and prescriptive, butofferslittletothe‘creativeprocess’.Abetterstrategyistocontactamemberoftheeditorialboard. All are experienced authors and will be happy to offer advice and support. Articles in this issue are linked by that most appealing property of minerals, their colour. For readers with a little time on their hands Light and Color in Nature and Art (Williamson and Cummins, 1983) providesanexcellentintroductiontothesubjectandisoftenavailablefornext-to-nothingviainternet booksellers. The same, sadly, is not true of Kurt Nassau’s classic Physics and Chemistry of Color, which provides a technical perspective. Opening the batting in this year’s JRS, Steve Rust describes a specimen obtained in 1973 by John Jones from the Hucklow Edge Vein at Ladywash Mine in Derbyshire. His sharp eyes spotted the rare copper sulpharsenide enargite. Steve’s article illustrates the value of referees. All articles are scrutinised by two independent and knowledgeable experts who check facts and make comments on interpretations. This should reassure prospective authors as it helps to avoid mistakes and ensure accuracy. Arsenic-bearing minerals are rare in Derbyshire; the literature (e.g. Ford et al., 1993) recordsonlyarsenopyrite,enargiteandmimetite.DuringareviewoftheLadywasharticle,JohnJones pointed out a probable error in the last of these. In 1872, when lead mining was in decline, local smelters purchased 326 tons of ‘linnets’ which had been stockpiled at sixteen different lead mines. Someofthismaterialwasdescribedas‘brownlinnets’,anditwasassumed,onthebasisofcolour,that ‘brownlinnets’weremimetite.Johnpointsoutthatthereisnoevidenceforthis.Colourisnotareliable guide to the composition of lead-bearing apatite-group minerals; modern analyses show that all Derbyshire ‘linnets’, brown or otherwise, are pyromorphite. Ladywash Mine may be the premier specimen locality in Derbyshire, a county which is not lacking in mineralogical superlatives. It furnished the front cover illustration for Minerals of the English Midlands (Starkey, 2018). Don Edwards, who started Tideswell Dale Rockshop in 1971, recalled that in the early years one of the miners supplied a van load every week. And yet there is little recorded in the literature of the specimens it produced. A Ladywash calcite makes a worthy frontispiece (Fig. 1) and one of Don’s paintings features on the back cover. A detailed article is overdue! In the discussion section of his article, Steve observes that Russell Society members have had access to New Milldam Mine, which works the same vein system as Ladywash, for many years.

FOREWORD I have much pleasure in introducing the Lohit Distri<^ Gazetteer, the first of a series of District Gazetteers proposed to be brought out by the Government of Arunachal Pradesh. A'Gazetteer is a repository of care­ fully collected and systematically collated information on a wide range of subjects pertaining to a particular area. These information are of con­ siderable importance and interest. Since independence, Arunachal Pra­ desh has been making steady progress in various spheres. This north-east frontier comer of the country has, during these years, witnessed tremen­ dous changes in social, economic, political and cultural spheres. These changes are reflected in die Gazetteers. 1 hope that as a reflex of these changes, the Lohit District Gazetteer would prove to be quite useful not only to the administrators but also to researdi schplars and all those who are keen to know in detail about one of the districts of Arunachal Pradesh.

  • Modeling Effective Stiffness Properties of IAD Fabrics
    AIAA 2011-2568 Modeling Effective Stiffness Properties of IAD Fabrics Scott M. Murman Srinivasan A. Suresh* [email protected] [email protected] NASA Ames Research Center, Moffett Field, CA, USA Princeton University, Princeton, NJ, USA Abstract A model for the mechanical stiffness properties of bladder fabrics for inflatable decelerators under high stress conditions is developed. This planar orthotropic model uses understanding of the fabric behavior, analytical modeling, numerical simulations, and available experimental data to characterize the fabric stiffness (elastic modulus), contraction (Poisson’s ratio), and shear modulus. The derived model is designed to integrate with standard finite-element methods and is validated against available static test data for two types of silicone-coated Kevlar fabric using the commercial LS-DYNA solver. 1 Introduction NASA is investigating inflatable aerodynamic decelerator (IAD) concepts to improve the deliv- ery of high-mass missions to the surface of Mars[1, 2]. IADs typically deploy pressurized sections constructed from lightweight impermeable fabrics to decrease the ballistic coefficient of the entry ve- hicle during descent (cf. Fig. 1). These concepts also have the potential to control the aerodynamic response, e.g., by forcing the bluff-body separation location using a “burble fence.” High-fidelity analysis of these concepts requires prediction of the fabric response in a complex aerodynamic en- vironment. Detailed predictions of the fabric stiffness, damping, and potential for wrinkling (buck- ling) under dynamic and thermal loading are required. This data is difficult to obtain from sub-scale or ground testing, and it is anticipated that validated numerical methods will fill this role.

  • Design Rules for Discovering 2D Materials from 3D Crystals
    Design Rules for Discovering 2D Materials from 3D Crystals by Eleanor Lyons Brightbill Collaborators: Tyler W. Farnsworth, Adam H. Woomer, Patrick C. O'Brien, Kaci L. Kuntz Senior Honors Thesis Chemistry University of North Carolina at Chapel Hill April 7th, 2016 Approved: ___________________________ Dr Scott Warren, Thesis Advisor Dr Wei You, Reader Dr. Todd Austell, Reader Abstract Two-dimensional (2D) materials are championed as potential components for novel technologies due to the extreme change in properties that often accompanies a transition from the bulk to a quantum-confined state. While the incredible properties of existing 2D materials have been investigated for numerous applications, the current library of stable 2D materials is limited to a relatively small number of material systems, and attempts to identify novel 2D materials have found only a small subset of potential 2D material precursors. Here I present a rigorous, yet simple, set of criteria to identify 3D crystals that may be exfoliated into stable 2D sheets and apply these criteria to a database of naturally occurring layered minerals. These design rules harness two fundamental properties of crystals—Mohs hardness and melting point—to enable a rapid and effective approach to identify candidates for exfoliation. It is shown that, in layered systems, Mohs hardness is a predictor of inter-layer (out-of-plane) bond strength while melting point is a measure of intra-layer (in-plane) bond strength. This concept is demonstrated by using liquid exfoliation to produce novel 2D materials from layered minerals that have a Mohs hardness less than 3, with relative success of exfoliation (such as yield and flake size) dependent on melting point.
