Infrared spectroscopy

see in the heat, well now you can with the infrared camera? The infrared camera is a non-contact device that can detect infrared energy and heat. Infrared can also measure the heat radiation by an object. The infrared camera can show us many things like how much heat something has and the object's temperature. The infrared camera is a much-needed device because the light and the heat can bring us special information that our eyes can't see. The infrared camera heat sensor can be very precisely quantified

fundamental thing it relies upon, light. What we call light is but one part of a much wider spectrum, electromagnetic radiation. As humans we are only able to see but a part of this spectrum. Some animals can see a wider spectrum of light, ultraviolet and infrared for example. This ability to see what we cannot, can be mimicked in photography through specialist films, such as infra-red and ultraviolet film. By limiting photography to just what we, as humans can see, are we not limiting the medium itself? This

As for the IR spectra of Unknown #40, the following peaks were formed and characterized in the following: a sharp, strong peak at 3304 cm-1 that best resembles an sp C-H bond, a sharp peak at 2937 cm-1 that best resembles an sp3 C-H bond, and a medium, sharp peak at 2119 cm-1 that best resembles a C≡C bond. As for the NMR spectra of Unknown #40, the following peaks were formed and characterized in the following: a triplet at 1 ppm that best resembles a saturated R-H, a multiplet at ~1.3-2 ppm that

The objective of experiment H was to identify an unknown compound using only infrared resonance (IR) and nuclear magnetic resonance (NMR) spectroscopy. IR helped determine the functional groups present in the molecule. NMR helped solve the structure of the molecule. The first step to solving my molecule was analyzing my IR spectra. The broad bands at 2958cm-1 indicated C-H alkane stretches. These stretches were sp3-hybridized bonds since they did not go past 3000cm-1. I found a strong carbonyl (C=O)

3.2. FT-IR examinations. Fourier transformation infrared spectra of formed composites have many identified bands which are: stretching vibration of O-H bond at about 3430, 1600 cm-1, stretching vibration of CO2 located at about 1410 cm-1, asymmetric stretching vibration at about 1110 cm-1 corresponding to S-O4 stretching mode (ν3) and out-of plane bending mode (ν4) of ettringite [Mollah et al. (1998); Hanna et al. (1995)] asymmetric stretching vibration (T–O–Si) at about 975 cm-1 where T = Si or

Since centuries, mobility have been the provocative issue for blind people or partially sighted people. Everybody including blind people needs to move. Hence there are some limitations with such devices as they are not much efficient. With the advancement of technology, several prototypes have been developed for blind assistance. They are usually known as blind stick. For the betterment of Pakistan and third world countries which are least developed proposing a user-friendly and cost effective

Li-Fi (Light Fidelity) Mian Siddique Ahmed Associate Editor, The Scientific Ravi In this modern era, wireless communication has become a requisite need like water and electricity which is part of our personal as well as our professional life. When we talk about wireless communication, the first word which comes to our mind is Wi-Fi. It uses 2.4-5 GHz RF (radio frequency) to deliver internet access around a wide area. As more and more users are connected to the network, the rate of data transfer gets

The gesture Gesture is the natural, nonverbal way that human can use to communicate with each other, and recently interface with computers and devices in order to have control upon them besides conventional input devices such as keyboard, mouse, and joystick. In general, gestures can be categorized into static and dynamic. • A static gesture refers to the position and poses of hand without any movement, which can be represented by a single image. • A dynamic gesture describes the hand movement
