*Textile Research Institute, ul. Gdanska 118, 90-520 Łodź, Poland e-mail: wsybilska@iw.lodz.pl Abstract By carrying out measurements of the thermoinsulation properties of clothing materials, we can obtain a lot of valuable information regarding the wide characteristics of these materials. Knowing thermoinsulation prop…
Particles sizes and melt processing of TiO 2 play improtant role in thermoplastic systems. The mechanical and morphological properties of polypropylene (PP)/TiO 2 composites were investigated by preparing the compostie by melt mixing technique in a twin screw extruder. The results show that after adding TiO 2 particle…
In this paper, we explore the effects of two organic additives (guar and a selectively hydrolyzed polyacrylamide) in the presence of chloride ions on copper electrodeposition using cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) at a rotating cylinder electrode (RCE). This paper also demonstra…
Results achieved using the infrared/THz spectroscopy of various inhomogeneous dielectrics in the Department of Dielectrics, Institute of Physics, Prague, during the last decade are briefly reviewed. The discussion concerns high-permittivity ceramics with inevitable low-permittivity dead layers along the grain boundari…
A novel POM compound containing the first Sb bicapped Keggin anion {SiMo(12)O(40)Sb(2)} and two different layers constructed from these anions stacked alternately has already been hydrothermally synthesized.
In this study, the synthesis and characterization of high surface area carbon-supported titania and titanium carbonitride aerogels is presented. An activated carbon aerogel with surface area greater than 2000 m2 g−1 was used as a support for the sol–gel deposition of titania. The resulting titania-coated carbon aeroge…
Voluminous specimens of individual Fe 5 SiC iron silicocarbide and Fe 3 C iron carbide phases were produced by mechanical alloying with subsequent pressing and considered as models of nonmetallic inclusions in carbon steels and siliceous cast irons. In an acidic sulfate solution, silicocarbide is highly active in hydr…
Polymers are demonstrated as an efficient medium to manipulate the size and fluorescence evolution of semiconductor nanocrystals (NCs). By tuning the nature of the polymers and the interactions between NCs and polymers, the growth rate of NCs could be controlled. This finding provides a new protocol for the design and…
Phenol formaldehyde (PF) resin was successfully produced from empty fruit bunch (EFB) fibres via liquefaction approach using sulphuric acid as catalyst. The produced PF resin was used to blend with EFB fibres as filler to produce PF-EFB composite boards. The effect of different percentages of EFB fibres on the density…
The model gases of toluene-air mixtures were prepared by blowing technical air into liquid toluene and then irradiated with an ILU-6 accelerator located at the Institute of Nuclear Chemistry and Technology (INCT), Poland. It was found that the decomposition efficiency of toluene increases with absorbed dose and decrea…
New phases with the general formula (MTe)(n)(Sb(2)Te(3))(Sb(2))(4) (n = 0, 1, 2, ; M = Ge, Ag) have been synthesized by quenching stoichiometric melts of the pure elements and subsequent annealing. These phases represent a combination of the well-known homologous series (Sb(2)Te(3))(m)(Sb(2))(k) and (GeTe)(n)(Sb(2)Te(…
In this study, an aging treatment was performed to investigate the microstructures and mechanical properties of Mg-10Li-0.5Zn (LZ101) alloy. Experimental results show that the LZ101 Mg-Li alloy exhibits a dual-phase microstructure of α (HCP) and β (BCC) phases, and has a good ductility. The 723 K solid-solution treate…
Small polymeric nanoparticles sized below 10 nm were effectively synthesized via free radical polymerization of a cross-linker in a glassy polymer matrix, owing to the successful prohibition of aggregation between the primary nanoparticles by the matrix.
The workability, strength and modulus of elasticity, drying shrinkage and creep, and chloride ion permeability as well as freeze-thaw resistance of the C60 high Performance concretes (HPCs) with manufactured sand (MS) containing crushed limestone dust in percents ranging from 3.5% to 14% were experimentally investigat…
In the present work the results of the research on the sol-gel synthesis and structure of cordierite (2MgO?2Al2O3?5SiO2), tialite (Al2O3?TiO2) and cordierite/tialite glass-ceramics as well cordierite containing 2 wt.% of Co and Co+Cu have been described and discussed. The sol-gel synthesis was carried out using differ…
The synthesis, crystal structure, and magneto-chemical characterization of two new unprecedented -phenoxo--carboxylato heterodinuclear complexes based on the Cr(salen) moiety (salen = N,N-bis(salicylidene)ethylenediamine), [MII(O2C(CH3)3)(OH2)2(mu-O2C(CH3)3)(-salen)CrIII(O2C(CH3)3)], M = Ni (2), Co(3) are reported. Th…
Indonesia is one of the countries having the largest rubber plantations in the world. Besides producing latex, rubber plantations produce also about 1500kg/hectare of rubber seeds, which has not been utilised optimally. Rubber seed oil may be able to be used for chamois leather tanning. Chamois leather is a popular le…
Austenitic stainless steels suffer intergranular attack in boiling nitric acid with oxidants. The intergranular corrosion is mainly caused by the segregation of impurities at the grain. An extra high purity austenitic stainless steel (EHP alloys) was developed with conducting the new multiple refined melting technique…
The realisation of molecular assemblies featuring specific macroscopic properties is a prime example for the versatility of supramolecular organisation. Microporous materials such as zeolite L are well suited for the preparation of host‐guest composites containing dyes, complexes, or clusters. This short tutorial focu…
While collagen type I is often used as a substrate for cell culturing and as a coating in biomedical implants, as far as we know a simple systematic study comparing the effects of the different presentations of collagen type I on the osteoblastic behavior of cells is missing. In this work, human bone marrow cells (hBM…
