A simple method for the synthesis of ZnO nanofilms composed of vertical array of quasi-1D ZnO nanostructures (quasi-NRs) on the surface was demonstrated via a 1D crystal growth of the attached nanoseeds under a rapid hydrolysis process of zinc salts in the presence of ammonia at room temperature. In a typical procedur…
Any tip functionalization of carbon nanotubes, for which the relative orientation between their (metallic) catalyst particle and the nanotube axis is essential, requires a detailed knowledge of the nature of the internal interface between the particle and the outgrown tube. In the present work, this interface is chara…
Abstract In the past two decades the energy-dispersive diffraction (EDD) method has become a powerful tool in many fields of materials research such as residual stress, texture, and crystal structure analysis, because of its favorable ratio of a comparatively low experimental effort in form of a simple and fixed instr…
Abstract In this study, the morphologies of three types of acrylonitrile–butadiene rubber (NBR)/polypropylene (PP) thermoplastic vulcanizates (TPVs) (with an NBR/PP blend ratio of 70/30) were compared. The TPVs were (1) an ultrafine fully vulcanized acrylonitrile–butadiene rubber (UFNBR)/PP TPV made by the mechanical…
Despite the intensive study on the famous metal–insulator transition, many questions regarding the evolution of the structural phase transition (SPT) in vanadium dioxide (VO 2 ) remain unresolved. Here, the lattice vibrations and SPT of VO 2 nanoparticles on a SiO 2 /Si(100) substrate with different applied voltage fr…
Adipose tissue engineering has been advocated for soft-tissue augmentation and for the treatment of soft tissue defects. The efficacy in terms of persistence of the engineered fat is, however, not yet understood and could depend on the nature of fabrication and application. The high metabolic demand of adipose tissue…
The synthesis and characterization of organic-inorganic hybrid materials that selectively capture sugars from model biomass hydrolysis mixtures are reported. 3-Aminophenylboronic acid (PBA) groups that can reversibly form cyclic esters with 1,2-diols, and 1,3-diols including sugars are attached to mesoporous SBA-15 vi…
We investigated by x-ray diffraction the Ga concentration dependences of the structural properties of Fe${}_{100\ensuremath{-}x}$Ga${}_{x}$ (galfenol) thin films grown on a ZnSe/GaAs(001) substrate, a material known for its high magnetostriction. By molecular beam epitaxy (MBE) we grew a series of (001)-oriented layer…
Abstract In this study, the degradability of linear low‐density polyethylene (LLDPE) and poly( L ‐lactic acid) (PLLA) blend films under controlled composting conditions was investigated according to modified ASTM D 5338 (2003). Differential scanning calorimetry, X‐ray diffraction, and Fourier transform infrared spectr…
Flat-knitted spacer fabrics offer a strong potential for complex shape preforms, which could be used to manufacture composites with reduced waste and shorter production times. A reinforced spacer fabric made of individual surface layers and joined with connecting layers shows improved mechanical properties for lightwe…
Fabrics made from natural fibers, such as wool and cotton, are susceptible to attacks from micro-organisms, which may damage the fabrics and harm the human body. Antimicrobial finishing of natural textile products may involve harmful and non-environmentally friendly chemicals. In this study, a natural antibacterial ag…
Emission and excitation spectra of undoped and Ln(3+) (Ln = Ce, Pr, Nd, Yb)-doped Lu(0.8)Sc(0.2)BO(3) were studied by vacuum ultraviolet spectroscopy, and the X-ray excited luminescence spectra were measured as well at room temperature. The undoped specimen presented two different emissions upon excitation at energies…
We report the fabrication of patterned binary polymer brushes via colloidal particle templating combined with electrodeposited ATRP, RAFT, and ROMP initiators. From the hexagonally close-packed template and subsequent patterned arrays, surface-initiated polymerization (SIP) demonstrated novel non-lithographically and…
Electronic screening strongly renormalizes the linear bands that occur near the Dirac crossing in graphene. The single bare Dirac crossing is split into two individual Dirac-like points, which are separated in energy but still at zero momentum relative to the K point. A diamond-like structure occurs in between as a re…
Here we test chemical strategies for the fabrication of free-standing porous silicon thin films that are covalently modified on one of their faces with biorecognition elements to guide the vertical self-assembly of optical structures. Chemical modification viahydrosilylation of alkenes followed by coupling of biomolec…
The frequent presence of Fe chlorosis in plants grown on calcareous soils is influenced by the forms of soil Fe present and their contents. Previous studies suggest that temporary soil flooding may increase Fe phytoavailability. To study flooding effects in relation to microbial activity in greater depth, we incubated…
A series of spin-crossover (SCO) iron(II) compounds, fac-[Fe(II)(HL(R))(3)]Cl·PF(6) [R = methyl (Me, 1), ethyl (Et, 2), n-propyl (n-Pr, 3), n-butyl (n-Bu, 4), and n-pentyl (n-Pen, 5)], were synthesized, where HL(R) denotes a series of [(2-methylimidazol-4-yl)methylidene]monoalkylamines. The cations fac-[Fe(II)(HL(R))(…
In recent years, the design of new low-molecular-weight gelators (LMWGs) has attracted considerable attention because of the interesting supramolecular architectures as well as industrial applications. In this context, the role of the organic solvent in determining the organogelation behavior is a central question. He…
1,3-Bis-(morpholin-4-yl-phenyl-methyl)-thiourea (MBT) was synthesized and their influence on the inhibition of corrosion on mild steel in various hydrochloric acid concentrations has been investigated by weight loss, potentiodynamic polarization, electrochemical impedance (EI), Tafel polarization, scanning electron mi…
Despite substantial progress in the field of vascular tissue engineering over the past decades, transition to human models has been rather challenging. The limited replicative life spans of human adult vascular cells, and their slow rate of collagenous matrix production in vitro, have posed important hurdles in the de…
