  • This study was performed to develop software sensorsto predict the BOD5 of river water and wastewater. The software sensors were based on the multiple-regression analysis using the dissolved organic carbon(DOC) concentration, UV light absorbance at 254nm and synchronous fluorescence spectra. River water samples and wastewater treatment plant (WWTP)effluents were collected at 1-hour interval to evaluatethe feasibility of the software sensors.

  • In the experiments, the chlorophyll fluorescence was measured under steady-state conditions, in 20 min predarkened intact leaves, and we have employed as the excitation source, a blue LED at 405 nm with 10 nm of bandwidth and delivering a maximum power of 2.2 mW. The choice relies upon the fact that its wavelength resides within the main absorption band of Chl a, producing much higher fluorescence emission intensity.

  • Adenosine 5’-triphosphate (ATP) là hợp chất cao năng quan trọng nhất, giữ vai trò cung cấp năng lƣợng trong mọi tế bào sống. Bởi vì trong phân tử ATP có hai liên kết phosphate cao năng, năng lƣợng tự do sẽ đƣợc giải phóng khi ATP bị thủy phân thành Adenosine 5’-diphosphate (ADP) và một phosphate vô cơ (Pi), hoặc Adenosine monophosphate (AMP) và pyrophosphate (PPi).

  • There have been various comprehensive and stand-alone text books on the introduction to Molecular Photochemistry available in market. A few fantastic books to mention are: ‘Modern Molecular Photochemistry of Organic Molecules’ by N. J. Turro et. al. and ‘Fundamentals of Photochemistry’ by K. K. Rohatgi- Mukherjee. These books along with others give crystal clear idea on the common topics both in pictorial and intuitive terms.

  • To measure mechanical stress in real time, we designed a fluorescence reso-nance energy transfer (FRET) cassette, denoted stFRET, which could be inserted into structural protein hosts. The probe was composed of a green fluorescence protein pair, Cerulean and Venus, linked with a stablea-helix.

  • Transmission electron microscopy (TEM) is a technique where the electron-beam is transmitted through an ultra-thin specimen, interacting with specimen as it passes through it. An image is formed from the interaction of the electrons transmitted through the specimen, which is then magnified and focused onto an imaging device, such as a fluorescent screen, a photographic film, or a charge-coupled device (CCD) sensor. This technique is capable of imaging at significantly high resolution than the light microscopes, owing to the small de-Broglie wavelength of electrons....
