A platinum shell for ultraslow ligand exchange: unmodified DNA adsorbing more stably on platinum than thiol and dithiol on gold
(Royal Society of Chemistry, 2015-08-04)Due to the ultraslow ligand exchange rate on Pt, non-thiolated DNA is adsorbed on platinum nanoparticles (PtNPs) more stably than thiolated and even dithiolated DNA on AuNPs. Adsorption kinetics, capacity and stability are ... -
Plausibility of Image Reconstruction Using a Proposed Flexible and Portable CT Scanner
(Bentham Open, 2012-06-04)The very hot and power-hungry x-ray filaments in today's computed tomography (CT) scanners constrain their design to be big and stationary. What if we built a CT scanner that could be deployed at the scene of a car accident ... -
Plethysms of Chromatic and Tutte Symmetric Functions
(The Electronic Journal of Combinatorics, 2022)Plethysm is a fundamental operation in symmetric function theory, derived directly from its connection with representation theory. However, it does not admit a simple combinatorial interpretation, and finding coefficients ... -
A Pluralistic Approach to Interactional Expertise
(Elsevier, 2014-09)The concept of interactional expertise – characterized by sociologists Harry Collins and Robert Evans as the ability to speak the language of a discipline without the corresponding ability to practice – can serve as a ... -
Poissonian potential measures for Lévy risk models
(Elsevier, 2018-09-01)This paper studies the potential (or resolvent) measures of spectrally negative Lévy processes killed on exiting (bounded or unbounded) intervals, when the underlying process is observed at the arrival epochs of an independent ... -
Polarity Control for Nonthiolated DNA Adsorption onto Gold Nanoparticles
(American Chemical Society, 2013-05-21)Gold nanoparticles (AuNPs) functionalized with thiolated DNA have enabled many studies in nanoscience. The strong thiol/gold affinity and the nanoscale curvature of AuNPs allow the attached DNA to adapt an upright conformation ... -
Policy Resistance Undermines Superspreader Vaccination Strategies For Influenza
(Public Library of Science, 2013-03-01)Theoretical models of infection spread on networks predict that targeting vaccination at individuals with a very large number of contacts (superspreaders) can reduce infection incidence by a significant margin. These models ... -
Political feasibility of 1.5°C societal transformations: the role of social justice
(Elsevier, 2018-04-01)Constraining global climate change to 1.5°C is commonly understood to require urgent and deep societal transformations. Yet such transformations are not always viewed as politically feasible; finding ways to enhance the ... -
Poly(Lactic Acid)-Based Biomaterials: Synthesis, Modification and Applications
(InTech, 2012-01-20)Chapter 11 entitled "Poly(Lactic Acid)-Based Biomaterials: Synthesis, Modification and Applications" from: "Biomedical Science, Engineering and Technology", book edited by Dhanjoo N. Ghista, ISBN 978-953-307-471-9, Published: ... -
Poly-L-arginine Coated Silver Nanoprisms and Their Anti-Bacterial Properties
(Multidisciplinary Digital Publishing Institute, 2017-09-27)The aim of this study was to test the effect of two different morphologies of silver nanoparticles, spheres, and prisms, on their antibacterial properties when coated with poly-L-arginine (poly-Arg) to enhance the interactions ... -
Polyamide 6.6 separates oil/water due to its dual underwater oleophobicity/underoil hydrophobicity: Role of 2D and 3D porous structures
(Elsevier, 2019-02-01)Porous polyamide functionalized by plasma or various coatings has been investigated for oil/water separation. In literature, polyamide has rarely been studied for oil removal, and this work investigated the performance of ... -

(Elsevier BV, 2019-02-01)Porous polyamide functionalized by plasma or various coatings has been investigated for oil/water separation. In literature, polyamide has rarely been studied for oil removal, and this work investigated the performance of ... -
Polymeric Foaming Predictions from the Sanchez-Lacombe Equation of State: Application to Polypropylene-Carbon Dioxide Mixtures
(American Physical Society, 2017)A simple off-lattice method of deriving the Sanchez-Lacombe equation of state is presented. The Sanchez-Lacombe equation of state for mixtures is shown to be thermodynamically inconsistent for all mixing rules in such a ... -
Polymeric rapid prototyping for inexpensive and portable medical diagnostics
(Society of Photo-optical Instrumentation Engineers, 2012-10-24)The advent of inexpensive CO2 laser systems has led to a wide range of demonstrations of microfabricated lab on chip systems built of acrylic. However, there has been little application of these systems to building ... -
Polymerization Data Mining: A Perspective
(Wiley, 2019-04-01)Nowadays, ‘Data mining’ is widely proposed by data scientists as the most accepted and powerful approach to properly handle the information explosion. Data mining is defined as the extraction of interesting patterns and ... -
Polynomial bounds for chromatic number II: Excluding a star-forest
(Wiley, 2022-10)The Gyárfás–Sumner conjecture says that for every forest H, there is a function fH such that if G is H-free then x(G) ≤ fH(w(G)) (where x,w are the chromatic number and the clique number of G). Louis Esperet conjectured ... -
Polynomial bounds for chromatic number VI. Adding a four-vertex path
(Elsevier, 2023-05)A hereditary class of graphs is -bounded if there is a function f such that every graph G in the class has chromatic number at most f(!(G)), where !(G) is the clique number of G; and the class is polynomially bounded ... -
Polynomial bounds for chromatic number VII. Disjoint holes.
(Wiley, 2023-05-14)A hole in a graph G is an induced cycle of length at least four, and a k-multihole in G is the union of k pairwise disjoint and nonneighbouring holes. It is well known that if G does not contain any holes then its chromatic ... -
