Ballistics; Fortifications; Redoubts; Macedonian Phalanx
(2009-07-23)These lecture notes written by James Dinwiddie discuss a number of topics related to the military including fortifications, ballistics, redoubts, and the Macedonian Phalanx. Dinwiddie mentions various materials for building ... -
Early Experiments
(2009-07-27)This journal by James Dinwiddie written ca. 1774 has a list of philosophical queries as well as a list of materials. This file consists of one journal that is 29 pages in length. -
Effects of Surface Structure on the Electrocatalytic Activity of Pt-based Nanoparticles: An X-ray Absorption Spectroscopy Study
(2019-01-15)With clean and renewable sources of energy being a major focus for modern societies, developing efficient means of energy storage is a necessity. Of the technologies currently available, electrochemical fuel cells stand ... -
LITHIUM AND OXYGEN UNDER HIGH PRESSURE: FINITE-T PHASE STABILITY AND MELTING
(2015)Understanding the phase diagram of materials as a function of pressure and temperature is one of the most fundamental problems in condensed matter physics. When materials are compressed, modifications of their electronic ... -
MACROMOLECULAR AND MOLECULAR CHEMISTRY OF PHOSPHORUS-NITROGEN CAGES AND RINGS
(2023-12-14)A new class of main group polymers containing three-dimensional phosphorus-nitrogen (PN) cage motifs in the backbone are described in this work. The PN cages prepared are rigid, robust but amenable to metathesis chemistry ... -
Mesoporous Silicon Nanoparticles for Solar-Driven Hydrogen Generation from Water
(2021-12-13)Solar-driven hydrogen (H2) production from water (water splitting) by semiconductor photocatalysts has potential as a sustainable and cost-competitive alternative to current H2 production technologies. In recent years, ... -
OPTIMIZING AND DESIGNING POSITIVE ELECTRODE MATERIALS FOR SODIUM ION BATTERIES
(2019-04-05)Sodium ion batteries have the potential to be a more sustainable alternative to the widely-used lithium ion batteries. Layered sodium transition metal oxides as positive electrode materials have been a focus of research. ... -
A Study of the Semiconductor and Thermoelectric Properties of Sputtered Mixed Metal-Oxide Thin Films
(2014-08-21)The effects of stoichiometric ratio, oxygen (both during sputtering and annealing), and annealing on the transistor and thermoelectric properties of zinc indium oxide (ZIO) and zinc tin oxide (ZTO) were studied. Thin films ... -
Synthesis and Characterization of Magnesium and Manganese Doped LiCoO2
(2017-07-17)LiCo1-2xMgxMnxO2 (0 ≤ x ≤ 0.05) positive electrode materials were prepared from Co1-2xMgxMnx(OH)2 (0 ≤ x ≤ 0.05) co-precipitated precursor materials by mixing precursor materials with Li2CO3 and heating. All precursor and ... -
Understanding the Magnesiothermic Reduction to Form Porous Silicon Nanoparticles for Stoichiometric Reactions
(2023-08-29)Porous Si NPs have been explored in applications such as optics, sensing, gas storage, drug delivery, high-capacity anode material, photocatalysts for H2 evolution and for the reduction of CO2. The pore network of porous ...
