Abstract Methyl methacrylate was copolymerized with propyl N , N ‐tetramethylbis(phosphonate)‐bis(methylene)aminemethyl methacrylate (MAC 3 NP 2 ). The thermal degradation and flammability of this modified poly(methyl methacrylate) (PMMA) were compared with those of pure PMMA using thermogravimetric analysis (TGA) and…
Measurements of the magnetic penetration depth $\ensuremath{\lambda}$ in the Fe-based superconductor Ba${}_{1\ensuremath{-}x}$Rb${}_{x}$Fe${}_{2}$As${}_{2}$ ($x=0.3$, 0.35, 0.4) were carried out using the muon-spin rotation ($\ensuremath{\mu}$SR) technique. The temperature dependence of $\ensuremath{\lambda}$ is well…
Abstract Entanglement couplings of dangling chains in a weak gel are found to be applicable to the design of a self‐repairing polymer. It is confirmed that a cleavage applied using a razor blade is healed at room temperature without any manual intervention. Further, the healing efficiency is improved when the molecula…
Effective formulations of hydrophobic drugs for cancer therapies are challenging. To address this issue, we have sought to nanoscale artificial oil bodies (NOBs) as an alternative. NOBs are lipid-based particles which consist of a central oil space surrounded by a monolayer of oleosin (Ole)-embedded phospholipids (PLs…
The aim of this article is to propose advances for the preparation of hybrid nanocomposites prepared by the combination of intercalation from solution and melt-processing methods. This research investigates the effect of the laponite RDS content on the thermal, structural, and mechanical properties of thermoplastic st…
The objective of this study was to develop a combination chemotherapy of implantation of a 3-bis(2-chloroethyl)-1-nitrosourea (BCNU)-loaded wafer and intracarotid perfusion of BCNU-loaded nanoparticles for glioma treatment in vivo. BCNU-loaded poly(D,L-lactic acid) (PLA) nanoparticles coated with transferrin (Tf) were…
We fabricated graphene pnp devices, by embedding pre-defined local gates in an oxidized surface layer of a silicon substrate. With neither deposition of dielectric material on the graphene nor electron-beam irradiation, we obtained high-quality graphene pnp devices without degradation of the carrier mobility even in t…
Microstructural developments in nanoceramics were investigated in 3Y‐TZP compacts with relative density ( RD ) exceeding 93%. Special attentions were paid to the evolutions of pore structures. It was found that the densification process of nanoceramic compacts with apparently close porosity was greatly jeopardized by…
The problem of surface plasmon excitation by moving charges has been elaborated by several different approaches, mainly based on dielectric response theory within either semi-classical or quantum mechanical frameworks. In this work, a comparison of the surface excitation effect between two different frameworks is made…
A special physical mode of plastic deformation in nanocrystalline, ultrafine-grained, and polycrystalline solids is suggested and theoretically described. The mode represents the cooperative grain boundary (GB) sliding and nanoscale grain nucleation (occurring through stress-driven splitting and migration of GBs) proc…
Freestanding Ge/GeO 2 core‐shell nanocrystals (NCs) with varying sizes and shell thicknesses were synthesized by a ball milling method. The core‐shell NCs consist of single crystalline Ge core and crystalline GeO 2 shell. With increasing milling time, sizes of the NCs decrease while GeO 2 shell layer thicknesses incre…
We report ${}^{75}$As NQR measurements on single-crystalline Ca(Fe${}_{1\ensuremath{-}x}$Co${}_{x}$)${}_{2}$As${}_{2}$ ($0\ensuremath{\le}x\ensuremath{\le}0.09$). The nuclear spin-lattice relaxation rate ${T}_{1}^{\ensuremath{-}1}$ as a function of temperature $T$ and Co dopant concentration $x$ reveals a gradual decr…
Gezielte Bekämpfung: Polysilsesquioxan(PSQ)-Nanopartikel mit einem aktiven PtIV-Agens (1; siehe Bild) eignen sich zur gezielten Freisetzung von Chemotherapeutika. Die Zytotoxizität von 1 übertrifft die von Oxaliplatin gegen vier Krebszelllinien in vitro und wird durch gezielte Abgabe noch erhöht. PEGyliertes und Anisa…
We propose an experimental-based tool for dealing with fluorescence modulation close to nanoparticles for application in studies of fluorophores in the vicinity of gold nanoparticles (AuNPs), typically addressed via theoretical models. We performed a photophysical characterization of fluorophores in the vicinity of Au…
To achieve enough reliability of monolithic ceramic capacitor, it is important to know the contribution of grain boundary and grain interior to its reliability and insulation resistance. As the number of grain boundaries per layer increased, mean time to failure (MTTF) increased. In addition, as the number of grain bo…
The π-extended cyclo[4]naphthobipyrrole 1a has been prepared via an Fe(III)-mediated oxidative cyclization of an alkyl-substituted naphthobipyrrole. The structure of this new expanded porphyrin, isolated as the deprotonated sulfate salt, was characterized by spectroscopic means, as well through a single crystal X-ray…
Achieving red emission from ZnO-based materials has long been a goal for researchers in order to realize, for instance, full-color display panels and solid-state light-emitting devices. However, the current technique using Eu(3+) doped ZnO for red emission generation has a significant drawback in that the energy trans…
MCM-41 synthesized at room temperature was functionalized with aminopropyltrimethoxysilane (APTMS). The functionalized MCM-41 were characterized by powder X-ray diffraction, scanning electron micrography (SEM), transmission electron-microscopy (TEM), nitrogen adsorption–desorption, and carbon, nitrogen, and hydrogen (…
In regenerative medicine, the generation of biocompatible substitutes of tissues by in vitro tissue engineering must fulfil certain requirements. In the case of human oral mucosa, the rheological properties of tissues deserve special attention because of their influence in the acoustics and biomechanics of voice produ…
The lamellar antiferromagnet CuCr${}_{1\ensuremath{-}x}$In${}_{x}$P${}_{2}$S${}_{6}$ (${T}_{N}$ \ensuremath{\approx} 32 K) rapidly loses magnetic percolation upon diamagnetically diluting the triangular Cu-Cr-P${}_{2}$ planar network with In${}^{3+}$ ions. For 0 \ensuremath{\le} $x$ 0.3 anti-ferroelectricity (${T}_{c}…
