Wallace, ‘Small molecule recognition of mephedrone using an anthracene molecular clip’, Chemical Communications, Vol. 52(47): 7474-7477, 2016. The version of record is available online at DOI: http://dx.doi.org/10.1039/C6CC03404G. Published by the Royal Society of Chemistry.An anthracene molecular probe has been synthesised and shown to target mephedrone, a stimulant drug from the cathinone class of new psychoactive substances (NPS). A protocol has been developed to detect mephedrone via the probe using NMR spectroscopy in a simulated street sample containing two of the most common cutting agents, benzocaine and caffeine.Peer reviewedFinal Accepted Versio

A Pyrene-Based Fluorescent Sensor for Zn\u3csup\u3e2+\u3c/sup\u3e Ions: A Molecular \u27Butterfly\u27

A simple pyrene-based triazole receptor has been synthesised and shown to self-assemble in the presence of ZnCl2 in an exclusively 2 : 1 ratio, whereas a mixture of 2 : 1 and 1 : 1 ratios are observed for other Zn2+ salts. The pyrene units are syn in orientation; this is supported by a strong excimer signal observed at 410 nm in the presence of ZnCl2 in acetonitrile. DFT calculations and 2D NMR support the proposed structure

Assessing the Energy Production Potential of Mississippi Crops and Crop Residue Using Adiabatic Bomb Calorimetry

A variety of crops and crop components are being considered for their potential as alternative fuel sources for synthesis of biofuels. Development and continued improvements in conversion technologies have increased potential sources of alternative fuels. More importantly, recycling of crop residues formerly discarded as waste may enhance the sustainability of agricultural production. We are interested in exploring the total potential energy stored in crops and crop residue. Caloric values of all portions of several agricultural crops commonly grown in Mississippi were measured by adiabatic bomb calorimetry to evaluate their potential as an energy source. Corn, cotton, rice, soybeans, sweet potatoes and winter wheat were included in this study. Crops were grown and harvested under traditional production practices. Total crop biomass was harvested, and separated into individual plant components. Total energy content of each plant component was determined using standard procedures for adiabatic bomb calorimetry. Additional parameters evaluated were moisture content, density, and ash content. The experimental results show that corn cobs, cotton seeds and stalks, soybean seeds and leaves, sweet potatoes, and wheat have sufficient energy to make them feasible to use as alternative fuel sources. Efficiency of conversion of biomass will reduce the net potential energy production of this biomass material

Molybdenum (Molybdaenum): Its History, Occurrence, Brief Inorganic and Bioinorganic Chemistry

This chapter describes the history, occurrence, and brief inorganic and bioinorganic chemistry of molybdenum, inclusive of the molybdate(VI) chemistry as researched by Alvin A. Holder and Tara P. Dasgupta.
