Novel sandwich composites made of syntactic foam core and paper skin were developed as potential building materials. Interface bonding between core and skin was controlled by varying starch content. Two different microsphere size groups were employed for syntactic foam core manufacturing based on the pre-mold processi…

Ethylene polymerization on a model Cr(II)/SiO(2) Phillips catalyst modified with gas phase SiH(4) leads to a waxy product containing a bimodal MW distribution of α-olefins (M(w) < 3000 g mol(-1)) and a highly branched polyethylene, LLDPE (M(w) ≈ 10(5) g mol(-1), T(m) = 123 °C), contrary to the unmodified catalyst whic…
In donor-acceptor mechanically interlocked molecules that exhibit bistability, the relative populations of the translational isomers--present, for example, in a bistable [2]rotaxane, as well as in a couple of bistable [2]catenanes of the donor-acceptor vintage--can be elucidated by slow scan rate cyclic voltammetry. T…
The aim of this study is to evaluate the applicability of adsorption models for understanding adsorption properties of adsorbents. For this study, the adsorption charateristics of NO3
The synthesis of poly(thienylene vinylenes) (PTV) has been attracting attention due to the low band gaps and high electrical conductivities of these materials, making them applicable for charge storage devices, transparent conductive coatings, and electrochromic devices. Unsubstituted PTV is an intractable polymer tha…
Fly ash, silica fume and rice husks are hazardous waste materials that have no use and in the past have been landfilled. However, landfilling is becoming expensive and causes contamination to soil and ground water. Utilisation of waste material in concrete is also very effective in overcoming the problems caused by th…
Im Zentrum des Geschehens: Die Oxidation von elementarem Palladium mit SO3 führt zu Pd(S2O7) (siehe Struktur; Pd rot, O blau, S gelb), das eine oktaedrische Sauerstoffkoordination des Pd2+-Ions aufweist. Dies führt zum Paramagnetismus der Verbindung, die darüber hinaus eine ferromagnetische Ordnung bei 11.7 K zeigt.
Abstract To obtain a photoresponsive hydrogel, poly(vinyl alcohol) (PVA) having coumarin residue as a pending group was crosslinked by photodimerizing the coumarin pendants. PVA having coumarin pendants was prepared by reacting the polymer with epoxypropoxy coumarin (EPC) in a strong alkali condition with EPC/PVA mola…
Abstract Wool fabrics were treated with atmospheric pressure helium glow discharge plasma in an attempt to improve felting and dyeing behavior with cold brand reactive dyes using cold pad‐batch method at neutral pH. On glow plasma treatment, the hydrophilicity of wool surface and its resistance toward felting was grea…
BACKGROUND AND OBJECTIVES: AD-MSCs (adipose-derived mesenchymal stem cells), as an easy obtainable population of multipotent cells, have been successfully applied in many diseases in animals. Having very similar properties and morphology to these collected from bone marrow, are very attractive object for regenerative…
Using the mixed ligands bis(3-pyridylformyl)piperazine (3-bpfp) and 5-nitroisophthalic acid (H2NIPH) or 3-nitrophthalic acid (H2NPH), four two dimensional (2D) copper or cadmium coordination polymers with different structural features formulated as [Cu(3-bpfp)(NIPH)(H2O)] (1), [Cu(3-bpfp)0.5(NPH)(H2O)2] (2), [Cd(3-bpf…
Orthorhombic Cu3SnS4 nano-cuboids and nanosheets were synthesized by using monoclinic Cu31S16 nanocrystals as seeds. Transmission electron microscopy and powder X-ray diffractometry were adopted to investigate the resultant nanocrystals and the structural transformation of monoclinic Cu31S16 to orthorhombic Cu3SnS4.
We investigated the effect and feasibility of hyperthermia treatment on subcutaneous pancreatic cancer in female Kunming mice, using a murine pancreatic cancer cell line (MPC-83) established by us and found in this study to originate from epithelial pancreatic acinus. Magnetic fluid (MF) with ferromagnetic particles o…
Current lithium-ion battery (LIB) technologies are all based on inorganic electrode materials, though organic materials have been used as electrodes for years. Disadvantages such as limited thermal stability and low specific capacity hinder their applications. On the other hand, the transition metal oxides that provid…
This paper reports the optical effects of a two-dimensional (2D) SiNx photonic crystal layer (PCL) on Y3Al5O12:Ce3+ (YAG:Ce) yellow ceramic plate phosphor (CPP) in order to enhance the forward emission of YAG:Ce CPP-capped high-power white light-emitting diodes (LEDs). By adding the 2D SiNx PCL with a 580 nm lattice c…

HiRadMat (High Irradiation to Materials) is a new facility under construction at CERN designed to provide high intensity pulsed beams to an irradiation area where material samples as well as accelerator component assemblies can be tested. The facility uses a 440 GeV proton beam extracted from the CERN SPS with a pulse…
This work presents a scanning electrochemical microscopy (SECM)-based in situ corrosion probing methodology that is capable of monitoring the release of zinc species in corrosion processes. It is based on the use of Hg-coated Pt microelectrodes as SECM tips, which offer a wider negative potential range than bare plati…
A comprehensive understanding of chemical interactions between water and actinide dioxide surfaces is critical for safe operation and storage of nuclear fuels. Despite substantial previous research, understanding the nature of these interactions remains incomplete. In this work, we combine accurate calorimetric measur…
