A similar effect to the well-known reverse Perlin effect was observed on the (1)JC-F coupling constants of α- and β-d-glucopyranosyl fluoride tetracetate, both in nonpolar and polar solution. This can be called "reverse fluorine Perlin-like effect", and it is shown to be ruled by dipolar interactions rather than by hy…
Two-dimensional materials awakened a strong interest in the scientific and technological communities due to their exceptional properties that can be tuned by the material thickness and chemistry. In order to correlate optical properties with crystallographic structure and morphology, in this work, the authors aim at s…
This work presents the study of the electrical conductivity in MWNT as a function of three different chemical functionalization conditions. Unmodified and chemically modified MWNT were characterized by microRaman spectroscopy, XPS and SEM whereas the electrical conductivity was determined by dust compression technique…
Abstract Collagen is increasingly used as material for medical devices because of its excellent biocompatibility. To achieve long‐term durability, the collagen materials are dried and subsequently sterilized. Most common sterilization methods are unsuitable as they cause denaturation. Currently, only ethylenoxide or γ…
The syntheses, structures, and magnetic properties are reported for three new Ce/Mn clusters with different Ce/Mn ratios: [Ce6Mn4O12(O2CMe)10(NO3)4(py)4] (py = pyridine) (1), [CeMn8O8(O2CCH2(t)Bu)12(DMF)14] (DMF = dimethylformamide) (2), and [Ce2Mn4O2(O2CMe)6(NO3)4(hmp)4] (3; hmp(-) is the anion of 2-(hydroxymethyl)py…
Abstract Adenosine 5′‐triphosphate (ATP) is a multifunctional molecule that participates in many important biological processes. Currently, fluorescence indicators for ATP with high performance are in demand. Reported herein is a novel water‐soluble triarylboron compound which displays an apparent ATP‐dependent fluore…
STM of amorphous silica bilayers reveals electronic heterogeneity between seemingly identical sites. The structure is constructed of 4–9 membered rings of corner sharing SiO4 tetrahedra. Certain oxygens bridging the larger rings vanish as the bias voltage is reduced while others bridging the same size rings are unaffe…
In the search to reduce the side effects, toxicity and assuring the desired effectiveness of the drugs, many efforts has been made to improve specific drugs’ delivery characteristics. Several carrier nanoparticles have been used to assist the drugs incorporation, absorption and transport through the bloodstream. Howev…
A versatile methodology to develop an inherently fluorescent and thus traceable multifunctional nanodelivery platform based on miktoarm polymers is reported. Miktoarm stars containing covalently linked tetraiodofluorescein dye, polyethylene glycol, and polycaprolactone self-assemble into micelles, and integrate multip…
The electrochemical properties of cellulose dissolved in NaOH solution at a Au surface were investigated by cyclic voltammetry, FTIR spectroscopy, the electrochemical quartz crystal microbalance technique, and electrochemical impedance spectroscopy. The reaction products were characterized by SEM, TEM, and FTIR and NM…
The electro-optical properties and reducing morphologies of the PDLC films were strongly influenced by the chemical structure of curable diglycidyl ether (DGEBA), and tri-functional trimethylol propane triglycidyl ether (TMPTGE) significantly. Higher driven voltage and contrast ratio were achieved when the PDLC films…
Numerous nanoparticle (NP) fabrication methodologies employ “bottom-up” syntheses, which may result in heterogeneous mixtures of NPs or may require toxic capping agents to reduce NP polydispersity. Tangential flow filtration (TFF) is an alternative “green” technique for the purification, concentration, and size-select…

The deployment of viscoelastic structures that have been held stowed for a given time duration can be formulated as a viscoelastic boundary value problem in which the prescribed condition switches from constant displacement to constant traction. This paper presents closed-form expressions for the load relaxation and s…
In this paper, we report a C3-symmetric liquid crystal (LC) with sixfold alkyl peripheries exhibiting an unusual smectic E-like organization in the LC state. Based on conformational considerations, the smectic assembly is attributed to the formation of an endo-type Y conformer of asymmetric triazolyl and benzylic grou…
Two Mn(ii) complexes with azide and a new zwitterionic tetracarboxylate ligand 1,2,4,5-tetrakis(4-carboxylatopyridinium-1-methylene)benzene (L(1)), {[Mn5(L(1))2(N3)8(OH)2]·12H2O}n () and {[Mn5(L(1))2(N3)8(H2O)2](ClO4)2·6H2O}n (), have been synthesized and characterized crystallographically and magnetically. and contai…
Unilamellar vesicles are for the first time used as soft-templates in the electropolymerization of polypyrrole membranes with nanoscale organization and mesoscale order. The dimensions of vesicles (∼100–1000 nm) used as templates and the electropolymerization conditions lead to the formation of highly organized polypy…
Microphase separation of block copolymers (BCPs) has been extensively studied because it leads to the self-assembled formation of periodic structures controlled on the scale of tens of nanometers. In particular, BCP-derived cylindrical microdomains have attracted considerable interest for various applications owing to…
Neutron diffraction measurements are presented measuring the responses of both magnetic and structural order parameters of parent and lightly Co-doped Ba(${\mathrm{Fe}}_{1\ensuremath{-}x}{\mathrm{Co}}_{x}$)${}_{2}{\mathrm{As}}_{2}$ under the application of uniaxial pressure. We find that the uniaxial pressure induces…
Abstract Lanthanide complexes (Ln=Eu, Tb, and Yb) that are based on a C 2 ‐symmetric cyclen scaffold were prepared and characterized. The addition of fluoride anions to aqueous solutions of the complexes resulted in the formation of dinuclear supramolecular compounds in which the anion is confined into the cavity that…
