chemistry organic books for download

I have reuploaded the following comprehensive
textbooks on Organic Chemistry, in view of the fact
that many of the old links, especially those on
rapidshare.de, have become broken. Where available,
both PDF and DJVU versions of books have been
uploaded. Both editions have been uploaded where two
editions were available, due to the fact that often
omissions of material from newer editions cannot be
justified, as in the case of Vogel's Practical Organic
Chemistry 3rd and 5th editions. These links should
last until at least February 2008.

To avoid the limitations that Rapidshare.com imposes
on those who are not holders of Rapidshare "premium"
accounts, you will either need to use a whole string
in succession of proxy-servers (configured in your
browser or download client) that can accept file
downloads (not all of them can), such as those
regularly listed on http://www.samair.ru/proxy (this
would also enable more than one file to be downloaded
at a time), or else disconnect from and reconnect to
the internet between downloads, so as to change your ip adress

7- By the Sky with its ingeniously devised paths (orbits).
51-The Dispersing, 7

The Arabic expression “zat-ul hubuk” means ingeniously devised paths (orbits). The expression connotes beautifully designed formations. The scintillating brilliance of the stars that has enchanted us ever since the beginning of our existence, the incomparable sight unfolded across the sky has always attracted our attention, overwhelming us. Numerous poems and prose works describe the charming sensations that the sky generates in the human breast. The rising and setting of the sun, the phases of the moon, the sky studded with stars give the picture of a steady state universe. The universe full of its orbits is not visible to the naked eye. Stars that move at incredible speeds seem stationary to us. The fact that all stars and heavenly bodies are in motion was only scientifically established after the discovery of the telescope and the advance of science. The number of galaxies in the universe exceeds hundreds of millions, each comprising more than one hundred million stars, some larger and some smaller than the sun. Our sun is comparably of middle size. These stars have many planets like the earth and the planets have their satellites like our moon. All these have come about after having detached from one single point. All these stars and planets and satellites have their respective orbits. The omnipotence of God is conspicuous in His creation. God who originated everything from a single point demonstrated that the skill involved was not inherent in that point; having generated from it billions of celestial bodies displayed the endlessness of His power and facility. Every one of these bodies moves in its own orbit so that the state of the universe changes every second. This variation takes place by the motion within the respective orbit of every star, planet and satellite. Every moment in the universe is a new occurrence: so is every instant of a star, a planet and a satellite.

ARGUMENT FROM MOTION

The process of motion has been the subject of study by many thinkers throughout history. Plato said that the source of motion must have been God and described the universe as being governed by a Designer who was good and beneficent. Aristotle inferred that God must be the Prime Mover, that He was the original source and cause of motion in the universe. Farabi, representative of the Islamic world, concluded that the Prime Mover was the source of all existence and that He, the Unmoved Mover, had generated the movement. The Ihvan-› Safa, a philosophical-religious association of the 10th century, produced encyclopedic works. This association underlined the motion of the universe, confirmed the process of creation out of nothing, drawing attention to the order reigning in the universe and the perpetual movement that proved the existence of God. A great many Christian thinkers like Thomas Aquinas saw the motion of the universe as an evidence of a Supreme Being.

The fact that the motion in the universe is not limited to our solar system or to a handful of stars but is spread all over space is a very important point since it is also a proof of the endlessness of the power of God. The attention that the verse draws to the orbits in space is also meaningful. Galaxies move in perpetual motion; their constituent billions of stars float in their respective pathways; the planets trace elliptical orbits around the stars; and the satellites make their rounds about the planets, motion inside motion. If motion had not been devised to be an intrinsic part of matter we could not have sat comfortably in our chairs to watch TV. Nor would the sun, the earth or our very selves exist. All these formations owe their existence to the moving objects. The movement of stars in their orbits, the movement of planets around the stars have rendered our existence possible and our sipping coffee while watching television. The creation of motion in an ingenious and regular order generating chain reactions, and our observation of precise, ordered and perfect movements in galaxies of macrocosm and in atoms of microcosm are flamboyant invitations to conceive God’s power and knowledge. There will certainly be people who will turn a deaf ear to these invitations. Verse 7 of the sura The Dispersing that draws our attention to the orbits is followed by the following verses:

8- You are surely caught in contradictions
9- Deviating therefrom are the deviators.
51-The Dispersing, 8-9

Nanotube forests grown on silicon chips for future computers,elecronic

Mechanical engineering doctoral student Baratunde A. Cola, from left, looks through a view port in a plasma-enhanced chemical vapor deposition instrument while postdoctoral research fellow Placidus Amama adjusts settings. The two engineers recently have shown how to grow forests of tiny cylinders called carbon nanotubes onto the surfaces of computer chips to enhance the flow of heat at a critical point where the chips connect to cooling devices called heat sinks. The carpetlike growth of nanotubes has been shown to outperform conventional "thermal interface materials." The research is based at the Birck Nanotechnology Center in Discovery Park at Purdue.

Study: Brain and heart development linked

ST. LOUIS, Oct. 2 (UPI) -- U.S. biomedical engineers have discovered some commonalities between the shaping of the brain and the heart during embryonic development.

Washington University Professors Larry Taber and Phillip Bayly are examining mechanical and developmental processes that occur in the folding of the brain's surface, or cortex.

Folding is very important in human brain development because some of the worst neurological problems such as schizophrenia, autism and severe retardation are associated with abnormal brain folding. Taber and Bayly hope that increased understanding of brain folding might someday help prevent such diseases.

"We're not sure of the similarities between heart looping and brain folding," Taber said. "But there are only a handful of processes that cells use to create shape and form in the embryo. Developing brain and heart cells have the same basic tool set, but somehow they integrate them in different ways."

The scientists are currently conducting research on newborn ferrets. The ferret is the smallest mammal that has a folded brain, and unlike humans, folding occurs after the animal is born.

Post doctoral researcher Gang Xu presented the research last week in Los Angeles during the annual meeting of the Biomedical Engineering Society.

Better Displays On Laptop Computers, Cell Phones Coming Soon

Science Daily — UCLA chemists working at the nanoscale have developed a new, inexpensive means of forcing luminescent polymers to give off polarized light and of confining that light to produce polymer-based lasers

The research, which could lead to a brighter polarized light source for LEDs in laptop computers, cell phones and other consumer electronics devices, currently appears in the journal Nature Nanotechnology.

The research was conducted by UCLA professors of chemistry and California NanoSystems Institute members Sarah Tolbert and Benjamin J. Schwartz, and colleagues, including Hirokatsu Miyata, a research scientist with Canon's Nanocomposite Research division in Japan.

The researchers have succeeded in taking semiconducting polymers -- plastics that consist of long chains of atoms that work as semiconductors -- and stretching them out in a silica (glass) host matrix so that they have new optical properties.

"If you have polymer chains that can wiggle like spaghetti, it's hard to make them all point in the same direction," Tolbert said. "What we do is take tiny, nanometer-sized holes in a piece of glass and force the polymer chains into the holes. The holes are so small that the spaghetti chains have no space to coil up. They have to lie straight, and all the chains end up pointing in the same direction."

Because the chains point in the same direction, they absorb polarized light and give off polarized light. Lining up the polymer chains also provides advantages for laser technology, because all the chains can participate in the lasing process, and they can make the light polarized without the need for any external optical elements, Tolbert said.

As a postdoctoral fellow, Schwartz was one of the original discoverers in the 1990s that lasers could be made out of randomly oriented semiconducting polymer chains.

"Our new materials exploit the fact that the polymer chains are all lined up to make them into lasers that function very differently from lasers made out of random polymers," Schwartz said.

The manner in which the polymer chains incorporate into the porous glass of the silica matrix helps to confine the light in the material, enhancing the lasing process by producing what is known as a "graded-index waveguide." In most lasers, confining the light is typically done with external mirrors.

"Our materials don't need mirrors to function as lasers, because the material that's lasing is also serving to confine the light," Schwartz said.

In combination, the alignment of the polymer chains and the confinement of the light make it 20 times easier for the new materials to lase than if a randomly oriented polymer sample were used. And because polymers can be dissolved easily in solvents, they are inexpensive to process. The glass host matrix with the aligned nanoscale pores is also inexpensive to produce.

"Usually polarized and cheap don't go together," Tolbert said.

The research opens the possibility of additional applications for the new materials as a brighter polarized source for displays in products with LED-type displays, including cell phones, laptops and Palm Pilots.

"If you take an inexpensive light source with which you could excite the aligned polymer chains and get the chains to reemit, you potentially have a more efficient way to generate polarized light." Tolbert said. "This would allow displays to be brighter with less power consumption, and you could get longer battery life."

Tolbert has collaborated with Canon for years on the development of this class of new materials.

The research is federally funded by the National Science Foundation and the Office of Naval Research and privately funded by Canon.

In addition to Tolbert, Schwartz and Miyata, co-authors include UCLA researcher and former postdoctoral scholar Ignacio Martini, UCLA chemistry graduate student Ian Craig, and UCLA chemistry graduate student William Molenkamp.
