We investigate the formation of micellar interpolyelectrolyte complexes (IPECs) from multicompartment micelles (MCMs) of polybutadiene- block -poly(1-methyl-2-vinylpyridinium methylsulfate)- block -poly(methacrylic acid) (BVqMAA) triblock terpolymers and polycations of opposite charge. As cationic material, predominan…
A novel, mild, and high yielding synthesis is developed for trithiocarbonate and allyl sulphide-containing AFT (addition–fragmentation termination) monomers. The image illustrates the novel core, linker, and end groups of the monomer array crosslinked by PETMP, through which polymer films of low stress and capable of…
The vitamin D receptor (VDR), a member of the nuclear receptor superfamily, functions as a ligand-dependent transcription factor for various genes. Hereditary vitamin D-resistant rickets (HVDRR), an autosomal recessive disease, is caused by mutations in the VDR. In particular, the missense mutations R274L and W286R in…
Nowadays molecular nanoporous networks have numerous uses in surface nanopatterning applications and in studies of host-guest interactions. Trimesic acid (TMA), a benzene derivative with three carboxylic groups, is a marvelous building block for forming 2D H-bonded porous networks. Here, we report a low-temperature st…
Surface heterogeneity plays an important role in controlling colloidal phenomena. This study investigated the self-aggregation and bacterial adsorption of self-assembled monolayer coated gold nanoparticles (AuNPs) with different surface compositional and structural heterogeneity. Evaluation was performed on AuNPs coat…
Intrinsic toroidal plasma rotation due to the neoclassical toroidal plasma viscosity (NTV) effect induced by a three-dimensional helical magnetic field ripple in tokamaks is investigated in this paper. The intrinsic rotation is determined self-consistently by searching for the roots of the ambipolarity constraint, aft…
URTeC 1596247 A great variety of factors can influence production, and it is often difficult to discriminate how significant the impact of a single factor is. The unconventional nature of the Bakken tight oil play requires considering both geological and technological aspects, as completion designs evolved at a rapid…
Vascularization remains one of the primary obstacles in the repair of bone defects. In the previous issue of Stem Cell Research &Therapy, Pedersen and colleagues show that co-immobilization of endothelial cells and mesenchymal stem cells in a tissue-engineered construct can achieve functional microvascular networks in…
This short communication provides preliminary experimental details on the structure–property relationships of novel biomedical kaolin–bacterial cellulose nanocomposites. Bacterial cellulose is an effective binding agent for kaolin particles forming reticulated structures at kaolin–cellulose interfaces and entanglement…
Six complexes based on a new rigid V-shaped ligand, 2,6-bis(3-(pyrid-4-yl)-1,2,4-triazolyl)pyridine (2,6-H 2 bptp), namely, [Cd 4 (2,6-bptp) 2 ( d -cam)( l -cam)(H 2 O) 2 ] n ·4 n H 2 O ( 1 ), [Cd 2 (2,6-Hbptp) 2 (Hbtc)] n ·4 n H 2 O ( 2 ), [Zn(2,6-bptp)(H 2 O)] n · n H 2 O ( 3 ), [(Mo 8 O 26 )Cu 2 (2,6-H 2 bptp) 2 ]…
The shape and size are the two important geometrical factors that affect the electronic screening in nano-materials. Here, we develop an analytical theory for electronic capacitance based on Thomas–Fermi screening in conjunction with ‘multiple scattering method’ for arbitrary-shaped nanostructures including electronic…
This work establishes a multiscale and multitechnique nondestructive approach as valid methodology for monitoring surface properties and evaluating the effectiveness of enzymatic removal of varnishes from paintings/polychrome artefacts. Mock-up samples (documented reconstructions of oil, tempera, and gilded layers on…
We present the results of our study about the deposition rate of focused electron beam induced processing (FEBIP) as a function of the substrate temperature with the substrate being an electron-transparent amorphous carbon membrane. When W(CO)6 is used as a precursor it is observed that the growth rate is lower at hig…
Composites based on polyvinylidene fluoride filled with barium titanate (PVDF/BT) submicrometric particles were prepared. To uniformly disperse BT particles within PVDF, high‐energy ball cryomilling was used. The effect of processing and the presence of BT particles on the structure and morphology of the composites we…
A temperature-dependent constitutive model based on the continuum damage mechanics (CDM) theory is developed to model the stress/strain behavior of C/SiC composites. A formulation of Helmholtz free energy with initial modulus and tangent modulus is proposed to describe the bilinear constitutive behavior of such materi…
The linear ideal magnetohydrodynamic (MHD) limits of the pedestal in\nITER scenarios associated with the preparation and realization of the\nnominal fusion gain Q = 10 (inductive scenario at 15 MA/5.3 T,\nhalf-field/half-current and intermediate H-mode scenario at 10 MA/3.5\nT), as well as the hybrid scenario at 12 MA…
The use of an electrospun polycaprolactone (PCL) nonwoven mat that is coated with a layer of chitosan (CS) containing active ingredient [tea tree oil (TTO)] represents an effective strategy for producing functional dressings. CS-coated porous PCL nonwoven mat (CS3/PCLNM) with various concentrations of active ingredien…
In this study, high‐intensity focused ultrasound (HIFU)‐induced thermal effects for solid polymer materials are investigated systematically. Infrared camera imaging is used to monitor temperature changes. The effects of polymer structure, HIFU power, and sample thickness on the thermal effect are studied. The results…
A systematic investigation is reported of the optimized geometry and electronic structure of trivalent lanthanide ions (Ln 3+ ) doped in hexagonal (β)-NaYF 4 nanocrystals in the basis of density functional theory with a spin polarization approach. A model Na 24 Y 23 Ln 1 F 96 nanocrystal with a single central lanthani…
Doped-graphene has attracted considerable attention in many fields because doping element can alter the electrical properties of graphene. In this paper, we synthesized ZnSe·xN2H4/graphene (ZnSe·xN2H4/GS) and ZnSe/nitrogen-doped graphene (ZnSe/N-GS) nanocomposites with p-n junctions via one-pot solvothermal process. T…
