Effect of operating conditions on size and morphology of amylose nanoparticles prepared by precipitation

12-12-2014 | Yan Dong, Yanjiao Chang, Qian Wang, Jin Tong, Jiang Zhou, Starch - Stärke, 2014

Nano‐sized amylose particles were prepared by precipitating amylose solution (using DMSO/water mixture as solvent) with absolute ethanol. Effects of operating conditions, including temperature and solvent composition for preparing amylose solution, amylose concentration, ethanol amount used for ...


Multicomponent gas diffusion in non‐uniform tubes

12-12-2014 | Thomas Veltzke, Lars Kiewidt, Jorg Thöming, AIChE Journal, 2014

Abstract In many technical processes gas multicomponent diffusion takes place in confinements that are rarely uniform in direction of their long axis (e.g., catalysts pores). Here we show that in conical tubes multicomponent diffusion is hindered. This effect increases with ratio of inlet to ...


Interfacing Microwells with Nanoliter Compartments: A Sampler Generating High-Resolution Concentration Gradients for Quantitative Biochemical Analyses in Droplets

12-12-2014 | Fabrice Gielen; Tomas Buryska; Liisa Van Vliet; Maren Butz; Jiri Damborsky; Zbynek Prokop; Florian Hollfelder, Analytical Chemistry, 2014

Analysis of concentration dependencies is key to the quantitative understanding of biological and chemical systems. In experimental tests involving concentration gradients such as inhibitor library screening, the number of data points and the ratio between the stock volume and the volume required ...


Sustainability, Vol. 6, Pages 9231-9243: Empirical Evaluation of the Effect of Heat Gain from Fiber Optic Daylighting System on Tropical Building Interiors

12-12-2014 | Munaaim, Muhammad Arkam C.; Al-Obaidi, Karam M.; Ismail, Mohd Rodzi; Rahman, Abdul Malek Abdul, Sustainability, 2014

A fiber optic daylighting system is an evolving technology for transporting illumination from sunlight into building interiors. This system is a solution developed by daylighting designers to reduce operational costs and enhance comfort. As an innovative technology, fiber optic daylighting ...


Properties Governing the Transport of Trace Organic Contaminants through Ion-Exchange Membranes

12-12-2014 | Marjolein Vanoppen; Annelise F.A.M. Bakelants; Dorien Gaublomme; Klaas V.K.M. Schoutteten; Julie Vanden Bussche; Lyn ..., Environmental Science & Technology, 2014

Ion exchange membranes could provide a solution to the selective separation of organic and inorganic components in industrial wastewater. The phenomena governing the transport of organics through the IEM however, are not yet fully understood. Therefore, the transport of trace organic contaminants ...


Equilibrium Adsorption of Hexahistidine on pH-Responsive Hydrogel Nanofilms

12-12-2014 | Gabriel S. Longo; Monica Olvera de la Cruz; Igal Szleifer, Langmuir, 2014

We present a molecular theory to study the adsorption of different species within pH-sensitive hydrogel nanofilms. The theoretical framework allows for a molecular-level description of all the components of the system, and it explicitly accounts for the acid–base equilibrium. We concentrate on ...


Determination of Total Protein Concentration in Solution Using Gold Electrode Modified with Silver Nanoparticles

11-12-2014 | Patrick Marcel Seumo Tchekwagep , Charles Péguy Nanseu‐Njiki, Emmanuel Ngameni, Ravi Danielsson, Thomas Arnebrant, T ..., Electroanalysis, 2014

Abstract Gold electrodes were modified with silver nanoparticles and Ag/AgCl redox conversion was recorded by cyclic voltammetry in protein containing electrolyte solution. The charge of the reduction peak decreased with the increase of the total protein concentration. This correlation was ...


Self‐Regulation Mechanism for Charged Point Defects in Hybrid Halide Perovskites

11-12-2014 | Aron Walsh, David O. Scanlon, Shiyou Chen, X. G. Gong, Su‐Huai Wei, Angewandte Chemie International Edition, 2014

Abstract Hybrid halide perovskites such as methylammonium lead iodide (CH3NH3PbI3) exhibit unusually low free‐carrier concentrations despite being processed at low‐temperatures from solution. We demonstrate, through quantum mechanical calculations, that an origin of this phenomenon is a ...


Microfabricated Ultrarapid Desalting Device for Nanoelectrospray Ionization Mass Spectrometry

11-12-2014 | Ivan A. Tibavinsky; Peter A. Kottke; Andrei G. Fedorov, Analytical Chemistry, 2014

Salt removal is a prerequisite for electrospray ionization mass spectrometry (ESI-MS) analysis of biological samples. Rapid desalting and a low volume connection to an electrospray tip are required for time-resolved measurements. We have developed a microfabricated desalting device that meets ...


Conditions for Critical Effects in the Mass Action Kinetics Equations for Water Radiolysis

10-12-2014 | Richard S. Wittman; Edgar C. Buck; Edward J. Mausolf; Bruce K. McNamara; Frances N. Smith; Chuck Z. Soderquist, Journal of Physical Chemistry A, 2014

We report on a subtle global feature of the mass action kinetics equations for water radiolysis that results in predictions of a critical behavior in H2O2 and associated radical concentrations. While radiolysis kinetics have been studied extensively in the past, it is only in recent years that ...
