A nearest-neighbor recogntion analysis has been performed in cholesterol-rich and cholesterol-poor liposomes derived from 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) in the presence of varying concentrations of chloroform. This analysis has yielded a funamentally new, molecular-level view of the interaction of general anesthetics with lipid bilayers, which may be relevant to their biological action; that is, DPPC Forms 1:1 complexes with CHCl3 in both membranes in the fluid bilayer state.

Amphoteric surface hydrogels derived from hydrogen-bonded multilayers: Reversible loading of dyes and macromolecules
Kharlampieva, Eugenia; Erel Göktepe, İrem; Sukhishvili, Svetlana A. (American Chemical Society (ACS), 2007-01-02)
We used hydrogen-bonded multilayers of poly(N-vinylpyrrolidone) (PVPON) and poly(methacrylic acid) (PMAA) as precursors for producing surface-bound hydrogels and studied their pH-dependent swelling and protein uptake behavior using in situ attenuated total reflection Fourier transform infrared spectroscopy and in situ ellipsometry. The hydrogels were produced by selective chemical cross-linking between PMAA units using carbodiimide chemistry and ethylenediamine (EDA) as a cross-linking reagent, followed by ...
Synthesis of aromatic poly(pyridinium salt)s and their electrochromic properties
Keshtov, M. L.; UDUM, YASEMİN; Toppare, Levent Kamil; Kochurov, V. S.; Khokhlov, A. R. (Elsevier BV, 2013-05-15)
Synthesis of a series of new conjugated electrochromic polymeric pyridinium salts containing main-chain triphenylamine and their electrochromic properties were demonstrated. All polymers exhibit intense UV absorptions at 336-338 nm in DMF and 340-343 nm in thin film form and fluorescence centered at 410-438 nm in DMF and 460-461 nm in thin film form. The electrochromic properties of the films were investigated by electrochemical and spectroelectrochemical methods. Reversible redox signals with stable electr...
Design Parameters and Principles of Liquid-Crystal-Templated Synthesis of Polymeric Materials via Photolithography
AKDENİZ, BURAK; Büküşoğlu, Emre (American Chemical Society (ACS), 2019-10-08)
The design parameters and principles for the synthesis of polymeric microscopic objects using a method that combines photolithography and liquid crystal (LC) molecular templates have been demonstrated. Specifically, mixtures of a reactive mesogen (RM257) and nonreactive LC (E7) were polymerized using UV light and a photomask. We used photomasks with circular, triangular, rectangular, square, star-shaped, and heart-shaped features to provide initial shapes to the objects. Then, the unreacted parts were extra...
Dust Effects on Nucleation Kinetics and Nanoparticle Product Size Distributions: Illustrative Case Study of a Prototype Ir(0)(n) Transition-Metal Nanoparticle Formation System
Özkar, Saim (American Chemical Society (ACS), 2017-07-04)
The question is addressed if dust is kinetically important in the nucleation and growth of Ir(0) nanoparticles formed from [Bu4N](5)Na-3(1,5-COD)(IrP2W15Nb3O62)-P-I center dot (hereafter [(COD)Ir center dot POM](8-)), reduced by H-2 in propylene carbonate solvent. Following a concise review of the (often neglected) literature addressing dust in nucleation phenomena dating back to the late 1800s, the nucleation and growth kinetics of the [(COD)Ir center dot POK8- precatalyst system are examined for the effec...
Encapsulated Hydrogels by E-beam Lithography and Their Use in Enzyme Cascade Reactions
Mancini, Rock J.; Paluck, Samantha J.; Bat, Erhan; Maynard, Heather D. (American Chemical Society (ACS), 2016-04-26)
Electron beam (e-beam) lithography was employed to prepare one protein immobilized hydrogel encapsulated inside another by first fabricating protein-reactive hydrogels of orthogonal reactivity and subsequently conjugating the biomolecules. Exposure of thin films of eight arm star poly(ethylene glycol) (PEG) functionalized with biotin (Biotin PEG), alkyne (Alkyne-PEG) or aminooxy (AO-PEG) end groups to e-beam radiation resulted in cross-linked hydrogels with the respective functionality. It was determined vi...
