4. Why PdO/TiON NP powders are chosen as photocatalyst? There are many reasons why PdO/TiON NP powders are chosen as a photocatalyst for MTBE mineralization under visible light. These reasons are listed and discussed as follows: 1- The synergistic effect. 2- The ease of synthesis. 3- The memory effect. 4.1 The synergistic effect Nowadays, modified TiO2 by metal and nitrogen is considered as one of the most promising TiO2 based materials for photocatalytic applications, which is able to…

of laser power and B content on ultrafine 3DQCN microstructure. 5.1.1. Research questions generation In the TMCs manufacturing, fabrication energy and reinforcement content are two significant input variables [1,9,11], which are related to laser power and B content in laser deposition. Based on the preliminary results (Figure 6 in §4.5), laser deposition with low level of laser power could fabricate the 3D TMC parts, however, the 3DQCN microstructure was not found inside the parts. Low laser…

is that beam can reel a particle in towards the source. Currently, there are three types of tractor beams, sonic, light, and laser beams. So far, each kind of beam has only been created to move particles or teeny tiny beads. There has been a lot of work towards tractor beam technology. There have been many advances in tractor beam technology such as sonic, light, and laser beams. One way to create a sonic tractor beam is using loudspeakers. The Universities of Sussex and Bristol did just…

Wilderness On The Lake, Wisconsin Dells!!! SPLASH!!!!! That was the sound that the waves made, pushing us back, while we were trying to go in deeper. I went to Wisconsin Dells for 4 days!! Though I got there late at night, but still it was very fun being there. There are many things that we did. Each day filled with lots to do! We stayed at a hotel called Wilderness On The Lake, I went there with Jessica, Angelina, and Pasha. Jessica is my cousin, she invited me to come with her so I could…

vision. In most cases, laser eye surgery is pain-free and is completed within 15 minutes for both eyes. It takes 24 hours to see improvement in vision without eye glasses or contact lenses.…

useful information about the properties of the object or phenomenon under test. Interferometers are used to make very small measurements that cannot be achieved with any other method. An important application of interferometry is in the Laser Interferometer Gravitation wave Observatory(LIGO) which is used to detect gravitational waves predicted by Einstein.1.1 The LIGO interferometer is like the Michelson Interferometer as shown in…

Technology has changed and advanced vastly over time. Through out these three articles a variety of technological advances are displayed. The first article is about how technology for treasure hunters have improved. The second article is how technology for hurricane hunters have improved. The third article is about how technology has advanced for people who explore looking for ancient civilizations. The most advanced technology for researchers today is the ones used for finding ancient…

As our society becomes more technologically advanced, many things advance with it. This includes criminal investigations, which can be aided by infrared spectroscopy. IR spectroscopy deals with the infrared region of the electromagnetic spectrum. This region is light with a longer wavelength and lower frequency than visible light. (Wikipedia) IR Spectroscopy is a method to identify substances based on their absorption of infrared wavelengths. It is a study of how the molecules of substances can…

if I told you that a laser can reach the earth all the way from space? You’d think it’s pretty cool right? Well it just so happens to be completely true! Scientists have created lasers to communicate from basically anywhere, and I’m here to tell you how it works. A laser shoots out a diverging beam that goes through the transmitter lens that creates a “well focused beam”. The well focused beam then goes through the receiver lens into the receiver diode. This is called laser communication. It is…

Laser Weapon Systems (LaWS) MIDN 3/C Sangrones, Joshua Jacksonville University Laser Weapon System In today’s standards, missiles and rockets are common when it comes to nations’ military warships. However, coinciding with the development of more advanced weapon systems, there are also advances in their counter measures. Such defense systems include the United States Navy’s Laser Weapon Systems (LaWS). Its creation allowed a more cost efficient and more effective way of countering enemy…
