Wollanka et al. describe the development of nephrogenic systemic fibrosis (NSF) 16 months after exposure to high-dose administration of gadobutrol (Gadovist, Bayer Schering Pharma, Berlin, Germany) and 1 month after iodinated contrast media in a patient established on haemodialysis ‘for several years’. The authors sug…
Examples of optimal designs for a fused-silica transmitted grating with high-intensity tolerance are discussed. It has the potential of placing up to 99% incident polarized light in a single diffraction order. The modal method has been used to analyze the effective indices for TE and TM polarization propagating throug…
The objective was to adapt Standard test methods for determining properties of apparel fabrics so these properties are a better reflection of fabrics when used in end-products, while retaining a controlled environment and thus allowing fabric comparisons 2 . Test methods in which properties are compared when fabrics a…
A novel multifunctional nanocomposite (P3OT-AuNPs-CI) consisting of gold nanoparticles coated with the conducting polymer poly(3-octylthiophene) and a molecule containing the cinnamate moiety has been developed. The cinnamate moiety is well-known for its photoreactive properties; that is, it can be rendered reactive t…
Meltable thermoplastic polyimide resins (MTPI) with designed polymer backbones and controlled molecular weights for advanced microelectronic packaging substrate application have been synthesized by thermal polycondensation of aromatic dianhydride and aromatic diamine in presence of endcapping agent. The thermoplastic…
Lattice grand canonical Monte Carlo simulations of heteropolymers adsorbing on heterogeneous surfaces are performed to help understand molecular recognition. The heteropolymers are self-avoiding walks of AB copolymers, which interact with a single heterogeneous surface composed of two different types of surface sites,…
Total internal reflection microscopy (TIRM) and video microscopy (VM) are methods for nonintrusively measuring weak colloidal interactions important to many existing and emerging applications. Existing analyses of TIRM measured single particle trajectories can be used to extract particle-surface potentials and average…
The taxonomy and valve ultrastructure of five naviculoid diatoms from Colorado are considered. A population of Placoneis navicularis (syn. Navicula semen sensu Donkin) shows the size diminution series of this rarely reported taxon. Scanning electron microscopy of both the internal and external valve morphology suggest…
Step by step: Two stairstep Cu4I4 coordination polymers 1 and 2 have selectively been synthesized by self-assembly of CuI and 1,4-bis(2-methylthioethoxy)benzene. γ-CuI nanocrystals have been prepared by thermal decomposition of the two stairstep Cu4I4 coordination polymers. Crystal transformation from the two polymers…
In this paper, we have investigated three external fields interacting with the four-level atomic system described by the density-matrix approach. The atomic system exhibits left-handedness with zero absorption and large negative refractive index. Varying the parameters of the three external fields, the properties of z…
The slippage-based opening at the seam line occurs on the woven fabrics due to movement in the fabric of the weft yarns over warp yarns (or warp yarns over weft yarns) at a sewn seam during utilization. Recurrent sitting down and standing up or continuously sitting down produces a load at the seam line and causes tran…
The nose cap demonstrator named Nose_2 has been tested for the second time in the plasma wind tunnel (PWT) facility which is part of the sharp hot structure (SHS) technology project, focused on the assessment of the applicability of ultrahigh temperature ceramics (UHTC) to the fabrication of high performance vehicles…
Abstract Four thiocyanato complexes with Co II and Ni II , [Co(NCS) 2 (htm) 2 (H 2 O) 2 ][Co(NCS) 2 (H 2 O) 4 ] · H 2 O ( 1 ), [Ni(NCS) 2 (htm)(CH 3 OH) 2 (H 2 O)] ( 2 ), [Ni(NCS) 4 (Hhtm) 2 ] ( 3 ), and [Co(NCS) 2 (apm) 2 (H 2 O) 2 ] · 2H 2 O ( 4 ) (htm = hexamethylenetetramine, apm = 2‐aminopyrimidine), were synthes…
The range of activation barrier heights for the Johari-Goldstein (JG) relaxation in glasses is shown to overlap the range for the main (alpha) relaxation, but to be on the average somewhat lower. This suggests the JG relaxation, like the alpha, involve transitions between megabasins in the energy landscape, and that t…
Abstract A sonochemical technique is used for in situ coating of iron oxide (Fe 3 O 4 ) nanoparticles on outer surface of MWCNTs. These Fe 3 O 4 /MWCNTs were characterized using a high‐resolution transmission electron microscope (HRTEM), X‐ray diffraction, and thermogravimetric analysis. The as‐prepared Fe 3 O 4 /MWCN…
Abstract We investigate the effect of less 3d electrons on the electronic and magnetic properties of half‐Heusler alloys CoMn 1− x Nb x Sb in a wide concentration range using first‐principles density‐functional calculations within the generalized gradient approximation. Our calculations indicate that for x < 0.5 th…
Lecithin/dodecylamine/lactose mixtures in ethanol/aqueous media led to the formation of sponge mesoporous silica (SMS) materials by means of tetraethoxysilane (TEOS) as silica source. SMS materials show a "sponge-mesoporous" porosity with a pore diameter of about 5-6 nm, in accordance to the length of a lecithin bilay…
A practical method to fabricate SWNT-conducting polymer nano-composites through poly(ionic liquid)-mediated process is developed. It is demonstrated that the poly(ionic liquid) layer along and around SWNT not only gives the facility for good dispersion of SWNT, but also provides a functionality to interlink SWNT with…
The spinning process is an important process in the Textile Industry. The yarn (output) coming out of the spinning process has a unique relationship with the input fibers. The input and output properties show a non-linear relationship between them. Many techniques, such as multiple regression, Artificial Neural Networ…
A tremendous growth in the field of carbon nanomaterials has led to the emergence of carbon nanotubes, fullerenes, mesoporous carbon and more recently graphene. Some of these materials have found applications in electronics, sensors, catalysis, drug delivery, composites, and so forth. The high temperatures and hydroca…
