Wetting Transition of the Caterpillar-Like Superhydrophobic Cu/Ni–Co Hierarchical Structure by Heat Treatment

23.09.2015 | Ning Wang; Yuhang Yuan; Yunwen Wu; Tao Hang; Ming Li, Langmuir, 2015

Caterpillar-like hierarchical structured Cu/Ni–Co coatings were fabricated by a simple two-step method of combined electroless and electrodeposition. Both contact angles and sliding angles were measured to investigate the hydrophobicity after stearic acid modification. The results revealed the ...


Monolayer to Interdigitated Partial Bilayer Smectic C Transition in Thiophene-Based Spacer Mesogens: X-ray Diffraction and 13C Nuclear Magnetic Resonance Studies

22.09.2015 | M. Kesava Reddy; E. Varathan; Nitin P. Lobo; Arun Roy; T. Narasimhaswamy; K. V. Ramanathan, Langmuir, 2015

Mesophase organization of molecules built with thiophene at the center and linked via flexible spacers to rigid side arm core units and terminal alkoxy chains has been investigated. Thirty homologues realized by varying the span of the spacers as well as the length of the terminal chains have ...


Fluorocarbon Nanodrops as Acoustic Temperature Probes

22.09.2015 | Paul A. Mountford; William S. Smith; Mark A. Borden, Langmuir, 2015

This work investigated the use of superheated fluorocarbon nanodrops for ultrasound thermal imaging and the use of mixed fluorocarbons for tuning thermal and acoustic thresholds for vaporization. Droplets were fabricated by condensing phospholipid-coated microbubbles containing C3F8 and C4F10 ...


Photochemistry of 4-Chlorophenol in Liquid and Frozen Aqueous Media Studied by Chemical, Compound-Specific Isotope, and DFT Analyses

22.09.2015 | Anna Zelmer; Ning Zhang; Kateřina Komínková; Dana Nachtigallová; Hans Hermann Richnow; Petr Klán, Langmuir, 2015

The photochemistry of 4-chlorophenol in liquid and frozen aqueous solutions and on the surface of ice grains yields substantially different photoproducts. Several complementary experimental and theoretical methods, such as trace analyses of the photoproducts, trapping experiments, ...


Amyloidogenic Properties of Short α-l-Glutamic Acid Oligomers

18.09.2015 | Agnieszka Hernik; Wojciech Puławski; Bartłomiej Fedorczyk; Dagmara Tymecka; Aleksandra Misicka; Sławomir Filipek; Wo ..., Langmuir, 2015

Poly-l-glutamic acid (PLGA) forms amyloid-like β2-fibrils with the main spectral component of vibrational amide I′ band unusually shifted below 1600 cm–1. This distinct infrared feature has been attributed to the presence of bifurcated hydrogen bonds coupling C═O and N–D (N–H) groups of the main ...


Investigation of the Role of Polysaccharide in the Dolomite Growth at Low Temperature by Using Atomistic Simulations

16.09.2015 | Zhizhang Shen; Izabela Szlufarska; Philip E. Brown; Huifang Xu, Langmuir, 2015

Dehydration of water from surface Mg2+ is most likely the rate-limiting step in the dolomite growth at low temperature. Here, we investigate the role of polysaccharide in this step using classical molecular dynamics (MD) calculations. Free energy (potential of mean force, PMF) calculations have ...


Stereocomplex Film Using Triblock Copolymers of Polylactide and Poly(ethylene glycol) Retain Paxlitaxel on Substrates by an Aqueous Inkjet System

15.09.2015 | Hiroharu Ajiro; Ayaka Kuroda; Kai Kan; Mitsuru Akashi, Langmuir, 2015

The stereocomplex formation of poly(l,l-lactide) (PLLA) and poly(d,d-lactide) (PDLA) using an inkjet system was expanded to the amphiphilic copolymers, using poly(ethylene glycol) (PEG) as a hydrophilic polymer. The diblock copolymers, which are composed of PEG and PLLA (MPEG-co-PLLA) and PEG and ...


Strong Acid–Nonionic Surfactant Lyotropic Liquid-Crystalline Mesophases as Media for the Synthesis of Carbon Quantum Dots and Highly Proton Conducting Mesostructured Silica Thin Films and Monoliths

10.09.2015 | Elif B. Olutaş; Fadime M. Balcı; Ömer Dag, Langmuir, 2015

Lyotropic liquid-crystalline (LLC) materials are important in designing porous materials, and acids are as important in chemical synthesis. Combining these two important concepts will be highly beneficial to chemistry and material science. In this work, we show that a strong acid can be used as a ...


Proton Diffusion Coefficient in Electrospun Hybrid Membranes by Electrochemical Impedance Spectroscopy

04.09.2015 | Leslie Dos Santos; Christel Laberty-Robert; Manuel Maréchal; Hubert Perrot; Ozlem Sel, Langmuir, 2015

Electrochemical Impedance Spectroscopy (EIS) was, for the first time, used to estimate the global transverse proton diffusion coefficient, DH+EHM, in electrospun hybrid conducting membranes (EHMs). In contrast to conventional impedance spectroscopy, EIS measurements were performed at room ...


Reverse Kebab Structure Formed inside Carbon Nanofibers via Nanochannel Flow

03.09.2015 | Min Nie; Dilhan M. Kalyon; Frank T. Fisher, Langmuir, 2015

The morphology of polymers inside a confined space has raised great interest in recent years. However, polymer crystallization within a one-dimensional carbon nanostructure is challenging due to the difficulty of polar solvents carrying polymers to enter a nonpolar graphitic nanotube in bulk ...
