The principle of atomic layer deposition is similar to chemical vapor deposition (CVD) except the ALD reaction breaks the CVD reaction into two half-reactions, keeping the precursor materials separate during the reaction. This is accomplished through sequential pulsing of special precursor vapors, each of which forms about one atomic layer during each pulse (reaction cycle). Reaction cycles are then repeated until the desired film thickness is achieved, versus chemical vapor deposition that introduces multiple precursor materials simultaneously.

The HPVA instruments are designed to measure the high-pressure adsorption isotherms with hydrogen, methane, carbon dioxide and other gases using the static volumetric method. Typical applications for this instrument include catalysts, zeolites, activated carbons, carbon nano tubes, and hydrides. Understanding the adsorption characteristics of materials is critical in the research and advancement of hydrogen storage, fuel cells and batteries, stack gas scrubbers, and hydrocarbon traps.

Fully automated instrument capable of conducting a comprehensive array of highly precise chemical adsorption and temperature- programmed reaction studies. The instrument enables the researcher to obtain valuable information about the physical properties of catalysts, catalyst support, and a variety of other materials.

PSI Large-Scale Photobioreactors are systems that create a controlled artificial environment for upscaling of photosynthetic microorganisms’ production and their metabolites. Standard systems are based on flat cultivation vessel (25 l or 100 l in volume) whereas customized systems comprising range of various cultivation tanks that meets customers’ requirements. The cultivation unit is operated by the stand-alone Control Unit.

Supercritical Fluid Extraction (SFE) typically uses supercritical CO₂ as the extraction solvent of choice as it has many advantages, including high matrix penetration and low viscosity at relatively low temperatures. SFE offers short extraction times and requires little or no organic solvents compared with other extraction techniques.

Quantum efficiency (QE) – also referred to as Incident Photon to Charge Carrier Efficiency (IPCE) - indicates the ratio of the number of photons incident on a solar cell to the number of generated charge carriers. In order to understand the conversion efficiency as a function of the wavelength of light impingent on the cell, the QE/IPCE measurement is critical for materials research and cell design. With this data, the composition and topography can be modified to optimize conversion over the broadest possible range of wavelengths.
