Stabilizing Effects of Phosphorus-Doped Silicon Nanoparticle Anodes in Lithium-Ion Batteries
(ACS Publications, 2023-01)Phosphorus-doped silicon has been reported to exhibit improved cycling stability and/or higher capacity retention than pure silicon as the anode in lithium-ion batteries. However, crystallite size and particle morphology ... -
Bispecific Anti-HIV Immunoadhesins That Bind Gp120 and Gp41 Have Broad and Potent HIV-Neutralizing Activity
(MDPI AG, 2021-07)We have constructed bispecific immunoglobulin-like immunoadhesins that bind to both the HIV-envelope glycoproteins: gp120 and gp41. These immunoadhesins have N terminal domains of human CD4 engrafted onto the N-terminus ... -
Biophysical Evaluation of Rhesus Macaque Fc Gamma Receptors Reveals Similar IgG Fc Glycoform Preferences to Human Receptors
(Frontiers Media SA, 2021-10)Rhesus macaques are a common non-human primate model used in the evaluation of human monoclonal antibodies, molecules whose effector functions depend on a conserved N-linked glycan in the Fc region. This carbohydrate is a ... -
Parenteral Exposure of Mice to Ricin Toxin Induces Fatal Hypoglycemia by Cytokine-Mediated Suppression of Hepatic Glucose-6-Phosphatase Expression
(MDPI AG, 2022-11)Ricin toxin is an agent of biodefense concern and we have been developing countermeasures for ricin threats. In doing so, we sought biomarkers of ricin toxicosis and found that in mice parenteral injection of ricin toxin ... -
Metabolomic and elemental profiling of blood serum in bladder cancer
(Elsevier BV, 2022-12)Bladder cancer (BC) is one of the most frequently diagnosed types of urinary cancer. Despite advances in treatment methods, no specific biomarkers are currently in use. Targeted and untargeted profiling of metabolites and ... -
Distinct Metabolic States Are Observed in Hypoglycemia Induced in Mice by Ricin Toxin or by Fasting
(MDPI AG, 2022-11)Hypoglycemia may be induced by a variety of physiologic and pathologic stimuli and can result in life-threatening consequences if untreated. However, hypoglycemia may also play a role in the purported health benefits of ... -
In vivo mechanotransduction: Effect of acute exercise on the metabolomic profiles of mouse synovial fluid
(Elsevier BV, 2022-03)Objective. Exercise is known to induce beneficial effects in synovial joints. However, the mechanisms underlying these are unclear. Synovial joints experience repeated mechanical loading during exercise. These mechanical ... -
Dynamic states of eIF6 and SDS variants modulate interactions with uL14 of the 60S ribosomal subunit
(Oxford University Press, 2023-01)Assembly of ribosomal subunits into active ribosomal complexes is integral to protein synthesis. Release of eIF6 from the 60S ribosomal subunit primes 60S to associate with the 40S subunit and engage in translation. The ... -
N-(Trimethylsilyl)-2-amino-5-nitrothiazole: An Efficient Reagent for the Direct Synthesis of 2-Amino-5-nitrothiazole-Based Antimicrobial Agents
(Georg Thieme Verlag KG, 2022-11)Here we report the synthesis of a novel reagent designed to prepare 2-amino-5-nitrothiazole (ANT) amides and analogues in high yields. N-(Trimethylsilyl)-2-amino-5-nitrothiazole (N-(TMS)-ANT) was prepared in 99% yield via ... -
Microbial Community Response to Polysaccharide Amendment in Anoxic Hydrothermal Sediments of the Guaymas Basin
(Frontiers Media SA, 2021-12)Organic-rich, hydrothermal sediments of the Guaymas Basin are inhabited by diverse microbial communities including many uncultured lineages with unknown metabolic potential. Here we investigated the short-term effect of ... -
Catalytic Ammonia Oxidation to Dinitrogen by a Nickel Complex
(Wiley, 2023-01)We report a nickel complex for catalytic oxidation of ammonia to dinitrogen under ambient conditions. Using the aryloxyl radical 2,4,6-tri-tert-butylphenoxyl (tBu3ArO⋅) as a H atom acceptor to cleave the N−H bond of a ... -
Does boron or nitrogen substitution affect hydrogen physisorption on open carbon surfaces?
(Royal Society of Chemistry, 2022-01)Incorporation of heteroatoms in carbon materials is commonly expected to influence their physical or chemical properties. However, contrary to previous results for methane adsorption, no technologically significant effect ... -
Methodological Studies of the Mechanism of Anion Insertion in Nanometer‐Sized Carbon Micropores
(Wiley, 2022-11)Dual-ion hybrid capacitors (DIHCs) are a promising class of electrochemical energy storage devices intermediate between batteries and supercapacitors, exhibiting both high energy and power density, and generalizable across ... -
Longitudinal analysis of the Five Sisters hot springs in Yellowstone National Park reveals a dynamic thermoalkaline environment
(Springer Science and Business Media LLC, 2022-11)Research focused on microbial populations of thermoalkaline springs has been driven in a large part by the lure of discovering functional enzymes with industrial applications in high-pH and high temperature environments. ... -
Slippery Paraelectric Transition-Metal Dichalcogenide Bilayers
(American Chemical Society, 2022-10)Traditional ferroelectrics undergo thermally induced phase transitions whereby their structural symmetry increases. The associated higher-symmetry structure is dubbed paraelectric. Ferroelectric transition-metal dichalcogenide ... -
Anti-CRISPR proteins function through thermodynamic tuning and allosteric regulation of CRISPR RNA-guided surveillance complex
(Oxford University Press, 2022-10)CRISPR RNA-guided detection and degradation of foreign DNA is a dynamic process. Viruses can interfere with this cellular defense by expressing small proteins called anti-CRISPRs. While structural models of anti-CRISPRs ... -
