Photocatalytic Products and Technologies Conference – PPTC’09
University of Minho, Guimaraes, Portugal during May 11-13, 2009.
PPTC’09 is the first Portuguese conference on photocatalysis and it will be a milestone for all researchers who are interested in this area and its applications. We’ll meet in the wonderful city of Guimarães to resume in three days the major advances in this field, discuss the industrial applications, on-going investigation and also potential networking opportunities. Furthermore, this conference will coincide with a COST Action 540 »PHONASUM« PHOTOCATALYTIC TECHNOLOGIES AND NOVEL NANOSURFACES MATERIALS – CRITICAL ISSUES Management Committee meeting, therefore broadening the interest scope and networking possibilities.
Over the last few years there has been a growing interest in the field of semiconductor photo-chemistry regarding the development of self-cleaning materials. Particular nanocrystalline thin films and nanoparticles are capable of acting as photoactive and photocatalytic materials, due to their intrinsic ability of removing pollutants in the gas phase or dissolved in water. The photocatalyst material plays an important role in the dissociation and mineralization of organic impurities on a particular surface, such as on glass, ceramic, metal or a polymer. The vehicle for this photocatalisation is simply solar light. Understanding the fundamental process and enhancing the photocatalytic efficiency of known catalysts has become a major research focus, bearing in mind industrial applications as materials that possess anti-fogging, self-cleaning or antibacterial activities for general purpose surfaces.
Topics of the conference:
Fundamental Science of Photocatalysis
Treatments of Water, Air and Soil Including Solar Technologies
Visible Light Responsive Photocatalyts
Dye-sensitized Solar Cells
Synthesis of New Photocatalytic Materials
Photocatalytic antimicrobial Materials

NanoteC is one of the longest running series of international nanoscale carbon conferences in Europe (since 1998). It brings together scientists working with nanoscale carbon materials: nanotubes, graphene, diamond- and fullerene-related nanostructures. While each of these materials attracts its own dedicated community of researchers, NanoteC draws on common themes and allows researchers to share insight into this unique element at the nanoscale. Elemental carbon shows remarkable variety in properties via simple covalent bonding, however other systems (for example containing nitrogen or metals) are becoming important and provide alternative components with unique mechanical and electronic properties. Nanotechnology requires an understanding of these materials on an atomic level and this will be the central theme. The NanoteC conferences are renowned for their relaxed and friendly atmosphere, with emphasis on discussion and participation. We endeavour to achieve as much student participation as possible, and we anticipate that the keynote talks will be strongly influential on the next generation of nanotechnology scientists. Contributed talks are also mainly attributed to young researchers. This year NanoteC09 will be in Brussels, Belgium, with 120 to 150 participants from around the world, 12 sessions (non-parallel) with about 10 keynote and 30 contributed talks, as well as a poster session, with posters available for discussion throughout the conference.
Timings and Social Programme
Early registration deadline:Wednesday 24th June
Conference:Wednesday August 26th – Saturday 29th 2009
- Round table debate: a general and open discussion will be held on themes such as carbon nanotube and nanocomposites production, nanocarbon characterisation, ethics and communication, etc. These are intended to give new people to the field a rapid introduction, and those more established to explore a topic in some detail together.
- The NanoteC Roadmaps: We plan to devise development roadmaps for different aspects of nanocarbon science and technology (for example nanotube production, sample standardisation)
- Breaking News Lectures: If presenting a poster, attendees may register for a “breaking news” slot; depending on demand there will be programme slots available for particularly new and exciting results.

The Tesla coil is one of Nikola Tesla’s most famous inventions. It is essentially a high-frequency air-core transformer. It takes the output from a 120vAC to several kilovolt transformer & driver circuit and steps it up to an extremely high voltage. Voltages can get to be well above 1,000,000 volts and are discharged in the form of electrical arcs. Tesla himself got arcs up to 100,000,000 volts, but I don’t think that has been duplicated by anybody else. Tesla coils are unique in the fact that they create extremely powerful electrical fields. Large coils have been known to wirelessly light up florescent lights up to 50 feet away, and because of the fact that it is an electric field that goes directly into the light and doesn’t use the electrodes, even burned-out florescent lights will glow.
Nanoporous membranes. Some of the most interesting applications for nanoporous membranes come from the ability of nanopores of certain sizes to let some substances pass and others not . . .
We present a procedure for high volume fabrication of nanopore membrane chips, combining low cost hot embossing for nanopore replication and conventional photolithography for manufacture of the membranes, alignment marks and break lines. The embossing masters are fabricated by electron beam lithography allowing customisation of the nanopore design. Nanopore membrane chips containing four membranes were fabricated and three of the membranes were structured with arrays of pores with three different diameters. Several different nanopore periods were tested. For pillar sizes in the embossing master of 460, 250 and 95 nm, optimization of the pattern transfer process resulted in nanopore sizes of 550, 330 and 140 nm. For the minimum periods employed for these three pore sizes of 1000, 500 and 300 nm, respectively, the membranes were found to be stable. This fabrication technology opens the way for high volume batch processing of nanostructured membranes, facilitating new avenues for research and technology.

||Simple Electric Generator – Video
1 min 16 sec
||Magnetic motor electric generator

This is an AC electric generator which lights up a tiny incandescent light bulb. The generator is made from a hollow-ended cardboard box with a nail through the center. The box has many turns of fine copper wire wound around it, with four large magnets clamped around the nail. When the nail and magnets are spun fast by hand, the little light bulb lights up dimly.
I wrote this article because I found lots of projects for making a simple electric motor, but nobody gave the secret for making a generator. Well, here it is: use strong magnets, lots of fine wire, and a special light bulb which only needs 1/2 volt. Also, don’t bother making a “commutator,” just hook the wires directly to the bulb. It’s much simpler that way, but the generator will produce AC (alternating current).
Before you start, here are some notes: you must use a special light bulb. Normal flashlight bulbs will not work. Also, you must use the large, strong magnets shown in the parts list. Smaller magnets won’t work. The wire must be #30 gauge or smaller. Also, you can improve the generator if you buy lots of extra kits of wire and wind it on the cardboard, since the bulb will light up even when the generator spins slowly. Three kits of Radio Shack wire is expensive, it’s cheaper to order just one $1.50 solenoid, but you’ll, need vise-grips pliers to pry apart the steel frame and remove the spool of wire.

HISTORY OF “ULTRA SIMPLE” GENERATOR
Around 1994 I was thinking about the ultra-simple electric motor which later became known on internet as the “Beakman Motor.” Wouldn’t it be cool if kids could also make an electric generator that simple? But it should be possible with parts from a Radio Shack store, since Radio Shack had the special light bulb as well as magnets and spools of electromagnet wire. After a few hours of experimenting I fould that I could just barely light up the 20 milliamps bulb by using a single spool of #30 wire from radio shack. But the wire had to be VERY close to a fast spinning magnet, and the magnet had to be composed of four powerful ceramic magnets in a stack.

How to Make an Inexpensive Vertical Wind Turbine – Part 1
Going with the Wind
Posted 07.06.2007 at 2:00 am
The slow-turning vertical-axis design is most efficient in gusts of 6 to 20 mph, so it’s ideal for relatively low-wind areas like western Michigan, where he lives. You can download plans at windstuffnow.com to build your own Lenz2. It’s not a quick weekend project, but once it’s up and running, paying the electric bill should be a breeze.
Build a Vertical Wind Turbine
Time: 3 Days
Easy | | | | |
- Construct the wings
Cut teardrop shapes from plywood, connect with four-foot rods, and cover with aluminum.
- Build the alternator
Glue magnets to two steel discs, tape copper-wire coils to a plywood disc (the “stator”), and slide all three discs over the shaft.
- Attach the parts
Clamp both ends of the shaft to the rectangular frame. Weld the wings’ arms to the bottom disc on the alternator, as well as to a steel disc at the top of the turbine.
- Mount the frame
Attach cables to the frame arms and stabilize with sandbags.
- Power the house
Wire the alternator to a rectifier, a device that converts the power from AC to DC, and connect it to the batteries. It takes four to six hours for Lenz’s turbine to fully charge his bank of eight batteries.
Another Build: The $30 Open-Source Turbine Go to velacreations.com to find instructions for off-grid DIY’er Abe Connally’s Chispito wind generator, a horizontal-axis-turbine design that more than 200 builders have built and helped perfect. Made entirely of salvaged parts, such as a treadmill motor and recycled sewer pipe, the Chispito can generate 100 watts in a 35mph wind. And if you’re able to find all the supplies, you can build it for less than 30 bucks.
