During the last 3 decades, PET has become a standard-of-care imaging technique used in the management of cancer and in the characterization of neurologic disorders and cardiovascular disease. It has ...

Stevia rebaudiana Bertoni is a plant native to south America, cultivated worldwide due to its use as a low-caloric sweetener. Stevia stems and leaves are rich in diterpenoid glycosides, mainly ...

We present a new rapid-acquisition HPLC detector based on a Hadamard-transform (HT) excitation-emission-matrix (EEM) fluorescence spectrometer allowing the acquisition of two-dimensional spectra at a ...

Isolate, fractionate and characterize extracts obtained from soursop leaves. Use of emerging green technologies such as microwave-ultrasound hybridization. The extracts contain kaempferol, ...

The fast and dramatic emergence of drug resistant bacteria is endangering the efficacy of antibiotics globally. The World Health Organization (WHO) have classified a number of bacteria as presenting ...

The authors provide a technical overview of the design and operating principles of variable wavelength and photodiode array detectors, and include historical perspectives and common practices in ...

Fluorescence detection can be a strong alternative to ultraviolet or other detectors for some compounds. Fluorescence detection can be a strong alternative to ultraviolet or other detectors for some ...

To date, solid-state lighting (SSL), visible light communication (VLC), and optical clock generation functionalities in the blue-green color regime have been demonstrated based on discrete devices, ...

Electro-optical detectors are used to measure or sense the radiation emitted or reflected by objects within the detector’s optical field of view (FOV). Passive systems operate without any illumination ...

Proper design of an antireflection coating involves managing the refractive index mismatch at the abrupt optical interface 1. The most straightforward approach places a single layer of intermediate ...

We present a simple microfluidic platform that uses biocompatible ferrofluids for the controlled manipulation and rapid separation of both microparticles and live cells. This low-cost platform ...
