Abstract Invited for the cover of this issue are the groups of A. Imberty (Grenoble), S. Matthews (East Anglia), S. Vidal (Lyon), S. P. Vincent (Namur) and J.‐F. Nierengarten (Strasbourg). The image depicts an artistic view of bacterial lectins attracted by glycoclusters constructed on a pillar[5]arene scaffold. Read…
BACKGROUND: The aim of this study was to develop a novel thermoresponsive material suited for tissue engineering and investigate the growth and harmless detachment of cells cultured on the surface of thermoresponsive tissue culture polystyrene (TCPS). METHODS: Thermoresponsive N-isopropylacrylamide (NIPAAm) and biocom…
Cubic NaGdF 4 :Yb 0.2 Er 0.02 ( α -NaGdF 4 ), self-assembly cubic NaGdF 4 :Yb 0.2 Er 0.02 , and high-resolution structure of hexagonal NaGdF 4 :Yb 0.2 Er 0.02 ( β -NaGdF 4 ) nanoparticles are prepared via the co-thermolysis of Gd(CF 3 COO) 3 and CF 3 COONa in the presence of 1-octadecene as stabilizer and oleic acid a…
This work proposes to examine the variability of the bone tissue healing process in the early period after the implantation surgery. The first part took into account the effect of variability of individual biochemical factors on the solid phase fraction, which is an indicator of the quality of the primary fixation and…
ABSTRACT The sorption of compressed carbon dioxide and methane in a series of all‐aromatic poly(etherimide) (PEI) thin films is presented. The polymer films are derived from the reactions between an arylether diamine (P1) and four different dianhydrides [3,3′,4,4′‐oxydiphthalic dianhydride (ODPA), 3,3′,4,4′ biphenylte…
INTRODUCTION: Theoretical advantages of fully bioresorbable scaffold (BRS) stem from transient vessel support without rigid caging. Therefore, it could reduce long-term adverse events associated with the presence of foreign materials. AREAS COVERED: This article will provide an overview of: drug-eluting BRS for variou…
An evaluation of chitosan gelling fibre dressing (KytoCel, Aspen Medical) was undertaken by tissue viability nurses in a large acute trust from December 2014--May 2015. The aim of this evaluation was to examine whether the gelling-fibre dressing can improve healing outcomes--reduction of bioburden and promotion of wou…
We demonstrate a procedure for the photochemical oxidative growth of iridium oxide catalysts on the surface of seeded cadmium selenide-cadmium sulfide (CdSe@CdS) nanorod photocatalysts. Seeded rods are grown using a colloidal hot-injection method and then moved to an aqueous medium by ligand exchange. CdSe@CdS nanorod…
We use molecular simulation to study the structural and dynamic properties of glassy nanoclusters formed both through the direct condensation of the vapor below the glass transition temperature, without the presence of a substrate, and via the slow supercooling of unsupported liquid nanodroplets. An analysis of local…
ABSTRACT Cotton knitted fabrics were treated with poly(ethylene glycol) (PEG) in the presence of polyhydric alcohol etherified dimethylol dihydroxy ethylene urea as the crosslinker and magnesium chloride hexahydrate as the catalyst. In wet–dry cycles, the fabrics treated with 30% PEG1500 in the presence of 15% crossli…
The liquid crystal (LC) alignment behaviors of LC cells fabricated with cellulose acetate films were investigated. These polymer films exhibited good optical transparency in the visible light region (400–700 nm). For example, transmittance value (92%) of the cellulose acetate film onto glass substrate at 550 nm is bet…
In this work, we demonstrate for the first time the electroluminescence (EL) from a mesa isolated p-i-n diode based on silicon nanocrystals (Si NCs) embedded in a SiO2 matrix fabricated on a dielectric substrate. The structure fabricated on a dielectric substrate ensures that the EL signal originates entirely from the…
Metal-insulator-metal metamaterial thermal emitters or absorbers have been widely investigated, and the fundamental and higher-order modes are generally excited in these metamaterial resonators. In this paper, we propose a methodology to widen the frequency interval between the fundamental and the second-order modes b…
The Kari–Culik tilings are formed from a set of 13 Wang tiles that tile the plane only aperiodically. They are the smallest known set of Wang tiles to do so and are not as well understood as other examples of aperiodic Wang tiles. We show that the $\mathbb{Z}^{2}$ action by translation on a certain subset of the Kari–…
In this research, we prepared hydrophobically modified agarose‐g‐poly(N,N‐dimethylamino‐2‐ethyl methacrylate) via the “grafting from” ATRP technique. First, agarose was hydrophobically modified by acylation of some of its OH groups with palmitoyl chloride. Then, the macroinitiator for ATRP was prepared by acylation of…
We theoretically study how the measurements of the flexoelectric coefficients in nematic liquid crystals are affected by the inclusion of the director-density coupling energy. It is shown that this investigation is quite relevant for interpreting the data of experiments.
Time-averaged images of the magnetization within single-layer spin-transfer oscillators have been obtained using the holography with extended reference by autocorrelation linear differential operator technique. Transport measurements on a Pd(5)-Cu(20)-Ni81Fe19(7)-Cu(2)-Pd(2) (in nanometers) stack with a 100 nm diamete…
The novel concept to well cloak the incident static magnetic fields by a heterostructure made of a superconductor (SC) and a ferromagnet (FM) has been proposed and verified recently. The performance of such heterostructure strongly depends on the involved materials and its geometrical configurations. We designed and b…
ABSTRACT Poly(N‐vinyl pyrrolidone)‐block‐poly(N‐vinyl carbazole)‐block‐poly(N‐vinyl pyrrolidone) (PVP‐b‐PVK‐b‐PVP) triblock copolymers were synthesized via sequential reversible addition‐fragmentation chain transfer/macromolecular design via the interchange of xanthate (RAFT/MADIX) process. First, 1,4‐phenylenebis(met…
We report high-resolution inelastic x-ray scattering measurements of the acoustic phonons of ${\mathrm{URu}}_{2}{\mathrm{Si}}_{2}$. At all temperatures, the longitudinal acoustic phonon linewidths are anomalously broad at small wave vectors revealing a previously unknown anharmonicity. The phonon modes do not change s…
