Scientific Ethics | Process of Science Enlarge In science, as in all professions, some people try to cheat the system. Charles Dawson was one of those people – an amateur British archaeologist and paleontologist born in 1864. By the late nineteenth century, Dawson had made a number of seemingly important fossil discoveries. Not prone to modesty, he named many of his newly discovered species after himself. For example, Dawson found fossil teeth of a previously unknown species of mammal, which he subsequently named Plagiaulax dawsoni. His most famous discovery, however, came in late 1912, when Dawson showed off parts of a human-looking skull and jawbone to the public and convinced scientists that the fossils were from a new species that represented the missing link between man and ape. In 1949, Kenneth Oakley, a professor of anthropology at Oxford University, dated the skull using a newly available fluorine absorption test and found that it was 500 years old rather than 500,000.

Weinberg Consultant East Amherst NY, USA E-mail: nweinberg@adelphia.net (May, 2002) Thousands of electrochemical reactions of organics have been catalogued to date. The essential difference between chemical and electrochemical processing is that the reactor is an electrolytic cell powered by a current source . There are many other differences seen in organic electrosynthesis compared to conventional organic synthesis. Advantages and disadvantages of electrosynthesis There are advantages and disadvantages to organic electrochemical processing. Electrosynthesis certainly has disadvantages too. Considering the advantages, critics question why there are so few commercial scale organic electrosyntheses.

The Chemical Suppliers: Customer Reviews Update, March 19: I've added a few more suppliers to the list, and broken out a third category for the mixed reviews. And I note in the comments that someone claiming to be Kathy Yu from 3B Chemicals is threatening me with legal action. The IP address resolves only to AT&T Internet Services, but there does appear to be someone from that name who works at 3B. I hope, for her sake and that of the company, that this is someone impersonating her, because whoever is leaving these comments is doing 3B no favors. And since I am reporting opinions, both my own and those of other contributors that I have no reason to doubt, and am doing so without malicious intent, I will cheerfully ignore all legal threats. OK, here are the lists of good companies and not-so-good companies, based on my experience and those of readers. I should note up front that I'm not listing the Big Guys, since (while they can have their ups and downs), you generally know that they're going to send you something.
Homemade Hydrogen Gas - How to Make Hydrogen Gas It's easy to generate hydrogen gas at home or in a lab using common household materials. Here's how to make hydrogen safely. Make Hydrogen Gas - Method 1 One of the easiest ways to obtain hydrogen is to get it from water, H2O. Make Hydrogen Gas - Method 2 There are two simple improvements you can make to improve the efficiency of hydrogen gas production. Make Hydrogen Gas - Method 3 You can get hydrogen gas by reacting hydrochloric acid with zinc. Zinc + Hydrochloric Acid → Zinc Chloride + HydrogenZn (s) + 2HCl (l) → ZnCl2 (l)+ H2 (g) hydrochloric acid (muriatic acid) zinc granules (or iron filings or strips of aluminum) Hydrogen gas bubbles will be released as soon as the acid and zinc are mixed. Homemade Hydrogen Gas - Method 4 sodium hydroxide (found in certain drain clog removers) aluminum (included in the drain removal products or you can use foil) Aluminum + Sodium Hydroxide → Hydrogen + Sodium Aluminate 2Al (s) + 6NaOH (aq) → 3H2 (g) + 2Na3AlO3 (aq)
Inside the Solar-Hydrogen House: No More Power Bills--Ever EAST AMWELL, N.J.—Mike Strizki has not paid an electric, oil or gas bill—nor has he spent a nickel to fill up his Mercury Sable—in nearly two years. Instead, the 51-year-old civil engineer makes all the fuel he needs using a system he built in the capacious garage of his home, which employs photovoltaic (PV) panels to turn sunlight into electricity that is harnessed in turn to extract hydrogen from tap water. Although the device cost $500,000 to construct, and it is unlikely it will ever pay off financially (even with today's skyrocketing oil and gas prices), the civil engineer says it is priceless in terms of what it does buy: freedom from ever paying another heating or electric bill, not to mention keeping a lid on pollution, because water is its only by-product. Slide Show: Photos show what makes this house work "The ability to make your own fuel is priceless," says the man known as "Mr. "I'm a self-sufficiency guy," he adds.
hydrogen fuel systems Hydrogen Fuel Systems can be composed of Electrolyzer or hydrogen generator (preferably powered by renewable source; solar or wind), Home Fueler or a metal hydride tank to store generated hydrogen, a fuel cell car also using the metal hydride tank, or fuel cell for home heating and other fuel cell home appliances.
