Cool Microcontact Printing To Fabricate Thermosensitive Microgel Patterns

13-09-2013 | Jiaxi Peng; Dan Zhao; Xiaofeng Tang; Fei Tong; Li Guan; Yapei Wang; Meining Zhang; Tingbing Cao, Langmuir, 2013

A facile method, cool microcontact printing (cool μCP), of fabricating microgel patterns under ambient conditions is developed. By using spontaneously condensed water on the surface of cold items and the phase transition of polymer microgels below the lower critical solution temperature (LCST), a ...


Controllable Superlubricity of Glycerol Solution via Environment Humidity

13-09-2013 | Zhe Chen; Yuhong Liu; Shaohua Zhang; Jianbin Luo, Langmuir, 2013

The effect of humidity on the lubrication property of glycerol solution between steel surfaces has been investigated in this paper. A stable superlubricity with a friction coefficient about 0.006 has been found under the relative humidity between around 40% RH and 50% RH. Especially, it is noted ...


Imaging Fluorescent Nanoparticles To Probe Photoinduced Charging of a Semiconductor–Solution Interface

12-09-2013 | Eric M. Peterson; Joel M. Harris, Langmuir, 2013

Optically transparent semiconductors allow simultaneous control of interfacial electrical potential and spectroscopic observation of chemistry near the electrode surface. Care must be taken, however, to avoid unwanted photoexcitation-induced charging of the semiconductor electrode that could ...


Influence of Headgroup on the Aggregation and Interactional Behavior of Twin-Tailed Cationic Surfactants with Pluronics

11-09-2013 | Rajwinder Kaur; Sugam Kumar; Vinod K. Aswal; Rakesh Kumar Mahajan, Langmuir, 2013

The surface tension measurements have been employed to characterize the micellar and interfacial behavior of pure and mixed systems of twin-tailed cationic surfactants: dimethylene bis(decyldimethylammonium bromide) (10–2–10), didecydimethylammonium bromide (DDAB), and ...


Titration of Free Hydroxyl and Strained Siloxane Sites on Silicon Dioxide with Fluorescent Probes

11-09-2013 | Joseph M. McCrate; John G. Ekerdt, Langmuir, 2013

A technique enabling the detection and quantification of low density sites on planar SiO2 surfaces is demonstrated. Fluorescent probes are used to titrate free hydroxyl and strained siloxane sites on the surface of amorphous SiO2 substrates in vacuum. The titration of free hydroxyl sites was ...


Self-Assembly Mechanism of Folate-Templated Mesoporous Silica

11-09-2013 | Rambabu Atluri; Muhammad Naeem Iqbal; Zoltan Bacsik; Niklas Hedin; Luis Angel Villaescusa; Alfonso E. Garcia-Bennett, Langmuir, 2013

A method to form ordered mesoporous silica based on the use of folate supramolecular templates has been developed. Evidence based on in situ small-angle X-ray scattering (SAXS), electron microscopy, infrared spectroscopy, and in situ conductivity measurements are used to investigate the ...


pH Effects on the Molecular Structure of β-Lactoglobulin Modified Air–Water Interfaces and Its Impact on Foam Rheology

06-09-2013 | Kathrin Engelhardt; Meike Lexis; Georgi Gochev; Christoph Konnerth; Reinhard Miller; Norbert Willenbacher; Wolfgang ..., Langmuir, 2013

Macroscopic properties of aqueous β-lactoglobulin (BLG) foams and the molecular properties of BLG modified air–water interfaces as their major structural element were investigated with a unique combination of foam rheology measurements and interfacial sensitive methods such as sum-frequency ...


Differential Adsorption of Small Molecules in Spatially Functionalized Porous Silicon Nanostructures

05-09-2013 | Chia-Chen Wu; Michelle Y. Chen; Michael J. Sailor, Langmuir, 2013

An experimental approach to rapidly quantify the relative affinity of a small molecule analyte for two different surfaces is described. The method uses optical measurements of high surface area porous Si thin films that contain two spatially distinct surface chemistries. The chemistries are ...


Roughness and Salt Annealing in a Polyelectrolyte Multilayer

04-09-2013 | Ramy A. Ghostine; Rana M. Jisr; Ali Lehaf; Joseph B. Schlenoff, Langmuir, 2013

The surface roughness of polyelectrolyte multilayers made from poly(diallyldimethylammonium chloride), PDADMAC, and poly(styrene sulfonate), PSS, was measured as a function of film deposition conditions. For dry multilayers, the significant roughness which builds up for thicker films is much more ...


Molecular Dynamics Simulation of SDS and CTAB Micellization and Prediction of Partition Equilibria with COSMOmic

04-09-2013 | Sandra Storm; Sven Jakobtorweihen; Irina Smirnova; Athanassios Z. Panagiotopoulos, Langmuir, 2013

Molecular dynamics (MD) simulations of the self-assembly of different ionic surfactants have been performed in order to obtain representative micellar structures. Subsequently, these structures were used to predict the partition behavior of various solutes in these micelles with COSMOmic, an ...
