If you are looking to buy a new LED TV, you might find it difficult to choose among the various models that are available on the markets today. This may be especially difficult when it comes to choosing between the top two players – Sony Bravia and Samsung TVs. It is easy to get...
Nanosolar has developed CIGS solar cells from copper indium gallium diselenide (CuInGaSe2). In this semiconductor material, the nanoparticles are inside a specially designed solar ink that is printed out on rolls made out of cheap aluminum foil (instead of glass substrate). Nanosolar was established in 2002. After a quiet period of 7 years of...
Oakton Waterproof Dissolved Oxygen Meter is a portable meter that simultaneously measures two quantities: dissolved oxygen and temperature. Temperature will affect the dissolved oxygen concentrations and therefore you would like to measure it at the same time with the DO values. Why is measuring dissolved oxygen important? Simply because it is a measure of...
The short answer to this question is Yes, Sony Bravia reads Exfat without any problem. That is, our kdl46ex720 does that, and as far as we know, all new models of Sony are able to do the same. Recently we purchased this Sony Bravia KDL kdl- 46 inch ex720 model. It is a great...
So, you are a proud owner of a Sony Bravia TV. You are satisfied with the television and you have marveled the great picture quality, but what about the file formats your Sony model supports? In particular, can it play mkv movies? After we have purchased our Sony BRAVIA KDL46EX720 LED TV, we started...
Portable solar cells used to be something exclusive, something you could only see in the movies. Not anymore. The super convenient Brunton CIGS solar cells (code name Solaris 26) are now available for everyone who needs them at a very affordable price. In this review, we will go through the most important features –...
There are two quantities that describe any given magnetic field: Magnetic induction, B and Magnetic intensity, H In the cgs (centimeter, gram, second) system of units B equals H, but in the international SI system they are identical up to a constant. In the international SI system magnetic induction is measured in Tesla (T)...
The spontaneous magnetization is the total magnetization that exists inside a microscopic volume of material when there is no magnetic field present. It depends on the temperature among other factors. The spontaneous magnetization of iron, Fe, at room temperature (RT) is 1 720 000 A/m. The spontaneous magnetization of cobalt, Co, at RT is...
This text is a review on the most important features of the latest Sony Bravia 2011 model – KDL46EX720. It was just recently that my wife and I decided to buy a new TV, and one of first choices was this Sony Bravia model. As we have been involved into the various technical details...
Earth’s magnetic field is 50 A/m, which is a very low value as compared to the common macroscopic magnets. This is an equivalent of about 50 µT (micro Tesla) or 0.5 Gauss. Earth’s magnetic moment, however, is large – 8∙1022 Am2. The Earth’s magnetic field value can be compared to the values other celestial objects....
