This paper presents the assessment of the neutron field near the VENUS reactor, particularly in areas near the reactor shielding where operators are frequently present during a reactor run. To obtain reference spectra in the area of interest, MCNPX simulations were performed. Reference spectrometry was also performed using a Bonner spheres system. The outcome of both calculations and measurements is compared.

Bitumen fume condensate (BFC) is a hazardous wastewater generated at asphalt reclamation and production sites. BFC contains a wide variety of potentially toxic organic pollutants that negatively affect anaerobic processes. In this study, we chemically characterized BFC produced at an industrial site and evaluated its degradation under anaerobic conditions.

Thionyl chloride (ClSO) serves as a common Cl atom source in widespread applications of chlorine chemistry though little is known about the reactivity and spectroscopy of the ClSO radical after a Cl-S bond cleavage. We performed a Pulsed Laser Photolysis experiment to detect ClSO from ClSO photolysis at 248 nm in a gas-flow reactor by time-resolved UV-vis transient absorption spectroscopy. A few chemical tests, using I and NO, suggested the structured absorption band between 260 and 320 nm belonged to ClSO radical and that the termolecular ClSO + Cl + M → ClSO association reaction occurred.

Rapid, low-cost and efficient assays for penicillinase activity and inhibition are of vital importance for therapeutics and diagnostics of bacterial resistance to antibiotics. Herein we report a novel approach for on-line enzyme assays for penicillinase utilizing capillary electrophoresis-integrated immobilized enzyme reactors (CE-IMERs). The CE-IMERs are fabricated based on penicillinase-mediated alginate hydrogelation, allowing single-step in-situ encapsulation of enzymes without any additional manipulation process.

Surfactants are amphiphilic molecules with large industrial applications produced currently by chemical routes mainly derived from oil industry. However, biotechnological process, aimed to develop new sustainable process configurations by using favorable microorganisms, already requires investigations in more details. Thus, we present a novel approach for biosurfactant production using the promising yeast Aureobasidium pullulans LB 83, in stirred tank reactor.

Background: The separation performance of seven polymer membranes for the nanofiltration of sodium lactate in fermentation broth was investigated. Each module was introduced into the test stand, and the system curve was obtained by recording the permeate flow velocity at different pump head levels. Performance benchmarks were good permeate quality, as determined by high permeate flow velocity, high sodium lactic concentration, low ion impurity concentration, and low organic impurity concentration.
