Enzyme Modification and Oxidative Crosslinking using Carboxylate-, Phenol-and Catechol-Conjugated 1,8-Naphthalimides
(John Wiley & Sons, 2019-04-16)The ground‐ and excited‐state interactions of β‐alanine, tyrosine and L‐dopa substituted 1,8 naphthalimides (NI‐Ala, NI‐Tyr and NI‐Dopa) with lysozyme and mushroom tyrosinase were evaluated to understand the mechanism of ... -
Using Clickers for Deliberate Practice in Five Large Science Courses
(NSTA, 2017-11-01)Clickers are often used as an active learning tool in face-to-face classes to enhance student engagement and assess student learning. In this article we share the variety of ways that we use clicker questions ... -
Using Reading Quizzes in STEM Classes—The What, Why, and How
(National Science Teachers Association, 2015)Many active learning pedagogies depend on students' preparing for class in advance. One common method for holding students accountable for this preparation is the use of reading quizzes. When used thoughtfully, reading ... -
Set of Highly Stable Amine- and Carboxylate-Terminated Dendronized Au Nanoparticles with Dense Coating and Nontoxic Mixed-Dendronized Form
(American Chemical Society, 2019-02-04)The synthesis of a novel poly(propyleneimine) (PPI) dendron in gram scale as well as its use in the formation of a highly stable, dendronized gold nanoparticle (AuNP)-based drug delivery platform is described herein. The ... -
Structural determinants for the activation of soluble guanylyl cyclase
(2018)Structural Determinants for the Activation of Soluble Guanylyl Cyclase Soluble guanylyl cyclase (GC-1) plays a vital role in vascular health by cyclizing GTP into cGMP, a potent vasodilator and inhibitor of platelet ... -
Optical characteristics of novel bulk and nanoengineered laser host materials
(SPIE, 2018-02-23)The hexagonal apatite single crystals have been investigated for their applications as laser host materials. Czochralksi and flux growth methods have been utilized to obtain single crystals. For low temperature processing ... -
Discovery Learning: Development of a Unique Active Learning Environment for Introductory Chemistry
(The Trustees of Indiana University, 2018-12-10)It is well established that active learning results in greater gains in student conceptual knowledge and retention compared to traditional modes of learning. However, active learning can be very difficult to implement in ... -
Chemiluminescent solid lipid nanoparticles (SLN) and interations with intact skin
(SPIE, 2009-08-24)We report the synthesis and characterization of a novel nanoparticle formulation designed for skin penetration for the purpose of skin imaging. Solid lipid nanoparticles (SLNs), a drug delivery vehicle, were used as the ... -
Simultaneous recording of the spectral, temporal, and polarization properties of emission spectra
(SPIE, 1997-05-07)We describe a system that records simultaneously the temporal profile of both linear polarization components of all wavelengths in an emission spectrum. Our excitation source is the vacuum ultraviolet storage ring of the ... -
Effect of additives: γ-Ray sensors based on ionizing organic nanocomposites
We have developed ionizing organic based composites which have demonstrated great promise for radiation sensing. Nickel oxide has been proven as an active material for detecting high energy radiation. The oxidation state ... -
Effect of additives: organic-metal oxide nanocomposites for γ-ray sensors
(SPIE, 2018-05-23)The transition metal oxide embodied organic composites have great promise for high energy radiation detection. The interaction of high energy radiation such as γ-rays with the organic composite can generate photoelectric ... -
Low Temperature Flux Growth of 2H-SiC and β-Gallium Oxide
We present brief overview of our study on the low temperature flux growth of two very important novel wide bandgap materials 2H-SiC and β-gallium oxide (β-Ga₂O₃). We have synthesized and grown 5mm to 1cm size single crystals ... -
Effect of organic flux on the colossal dielectric constant of CaCu3Ti4O12 (CCTO)
(SPIE, 2015-05-18)We have used low temperature organics to achieve orientation of the grains of Ca₂/₃Cu₃Ti₄O₁₂ (CCTO) compound to increase the resistivity. During the past fifteen years CCTO has been studied extensively for its performance ... -
Preparation and properties of plasmonic-excitonic nanoparticle assemblies
(De Gruyter, Berlin/Boston, 2019-01-11)The assembly of inorganic nanoparticles often leads to collective properties that are different from the combined properties of the individual components. In particular, coupling plasmonic and excitonic nanoparticles has ... -
Standoff detection using coherent backscattered spectroscopy
(SPIE, 2007-04-26)Intense laser pulses may be used for standoff detection of energetic materials. Coherent backscattered spectroscopy offers a tremendous advantage over other spectroscopic detection techniques in that it uses stimulated ... -
Novel 5′-Norcarbocyclic Pyrimidine Derivatives as Antibacterial Agents
(MDPI, 2018-11-23)A series of novel 5′-norcarbocyclic derivatives of 5-alkoxymethyl or 5-alkyltriazolyl-methyl uracil were synthesized and the activity of the compounds evaluated against both Gram-positive and Gram-negative bacteria. The ... -
Strong coupling and induced transparency at room temperature with single quantum dots and gap plasmons
(2018 Springer Nature Limited, 2018-10-01)Coherent coupling between plasmons and transition dipole moments in emitters can lead to two distinct spectral effects: vacuum Rabi splitting at strong coupling strengths, and induced transparency (also known as Fano ...
