In fact, an entire branch of chemistry is devoted to answering these theoretical questions, as well as to determining solutions to a host of other, more practical problems.
Organic chemistry is the study of carbon, its compounds, and their properties.
For hundreds of years alchemists toiled in their laboratories to produce a mythical substance known as the philosopher’s stone.
Don’t take it wrong, carbon indeed has its merits, but the recent carbon craze seems to be heavily tied to bandwagon mentality; whatever the pros are doing is what the masses want to do too.
It was true in the ‘70s with drilled-out components, in the ‘80s with copious amounts of hair gel and Briko shades, in the ‘90s with those horrific lycra shorts designed to look like blue jeans, and today with carbon racing bikes. A frame and fork weighs less than a six-pack of brew, they’ve got terrific road damping capabilities, are stiffer than an I-beam – at least initially – and most importantly, carbon fiber has an indisputable cool factor.
Emission reduction is also needed to counter the impacts on product cost of new regulations, green taxes and escalating fuel prices.
In this regard, locally available minerals, recycled materials and (industry, agriculture and domestic) waste may be suitable for blending with OPC as substitute, or in some cases replacement, binders.
You’re either new to the sport of cycling or you’ve been riding for a few years, learning the ropes on an old aluminum frame that’s one season away from the dumpster.
You’ve been watching all the Spring classics, the Giro, the Vuelta, and the Tour taking notes on who’s riding what.
But despite the alchemists’ intellectual firepower and experimental acumen, the philosopher’s stone lay forever out of reach.
The problem, Principe says, is that the alchemists did not yet know that lead and gold were different atomic elements—the periodic table was still hundreds of years away.
This paper presents a concise review of the current state-of-the-art and standards underpinning the production and use of OPC-based cements and concretes.
It outlines some of the emerging green alternatives and the benefits they offer.
The checkbook is in hand cocked and ready to besmirch every last dollar in your savings account, and all that’s left to do is negotiate with the shop so you at least have a little bit of cash left to buy some inner tubes.
