Starting material

This study uses chitin as a filler for a polyurethane composite foam. The obtained polymer composite materials (PCM) are examined the technological parameters of the foaming (start time, rise time, and apparent density), the physical-mechanical properties (the compressive stress, compression set, resilience), and the cross-link density.

It was demonstrated that Poly(p-Xylylene) (PPX) could be prepared from α,α’-Bis(Alkoxy or Aryloxy) –p-Xylenes via chemical vapor decomposition (CVD)- method. This is one-step process and there are side products by the CVD-process. This effect depends both on the CVD- condition and the properties of the starting monomer. The structure and thermal behavior of the material were characterized by FTIR, UVvis spectroscopy, elemental analysis, wide-angle X-ray diffraction, DTA and DSC.

The oxide reduction diffusion (ORD) procedure has recently been applied in synthesizing hydrogen storage materials AB5 for Ni-MH batteries. Starting from metal hydroxides and La oxalat precursor, superfine powder alloys LaNi5, LaNi4.5Co0.5 and LaNi3.87Mn1.13 were obtained by this “soft-chemistry” route. Chemical composition, structure and morphology of alloy phases were examined by different analysis techniques such as AAS, EPMA, X-ray and TEM. The H2-absorption and desorption behavior of crystalline products was determined by Sieverts’ method.

This shawl was inspired by tiny water droplets in nature, it will look beautiful in both lace or fingering weight yarn. If you use fingering weight yarn the simple stocking stitch section gives warm whilst still allowing the beauty of the lace border to show. Knitted top down the pattern can be scaled to use the most of your yarn, please read the re-sizing notes before starting. Materials Lace or Fingering weight yarn, 650m on 3.75mm needles using the standard sizing will produce a good sized shawl. See 'How much yarn?' for more details....

The aim of the study was to investigate the crystallization kinetics and solidification behaviour of Fe60Co8Mo5Zr10W2B15 bulk glass forming alloy. The solidification behaviour in near-equilibrium and non-equilibrium cooling conditions was studied. The eutectic and peritectic reactions were found to exist in the solidification sequence of the alloy. The bulk metallic glass formation was achieved by using two methods: quenching from the liquid state and quenching from the semi-state.

The first thing you’ll notice when you start using Office 2007 is the new and improved interface. There’s a lot of material in this book to get you up to speed on this. The interface is completely redesigned and contrary to what Microsoft implies, is going to take some time to master. There are no longer drop-down menus; instead, you select a tab at the top of the page, and the choices change underneath the tab depending on what you’ve selected. Some of the old standbys are hard to find though, like settings that were easily accessed in Office XP’s...
