In NCBJ, Poland a new laboratory for BNCT research is being constructed at MARIA reactor. In the first phase it will provide a thermal neutron beam for experiments with cellular samples and small animals. In the next step, a converter will be mounted to provide fast neutron beam. Beam shaping assembly will moderate the beam to epithermal energies allowing for irradiation human phantoms. The laboratory infrastructure as well as radiation shielding of the laboratory are being designed using MCNP6 software.

Beyond their classical role as cytotoxics, Platinum (Pt) coordination complexes recently joined the selected group of transition metals capable of performing bioorthogonal reactions in living environments. To minimize their reactivity towards nucleophiles, which limit their catalytic performance, we investigated the use of Pt(0) with different forms, sizes and surface functionalization. We report herein the development of PEGylated Pt nanodendrites with the capacity to activate prodyes and prodrugs in cell culture and in vivo.

Magnetic composites (MC) prepared from magnetite nanoparticles (MNP) and activated carbon from bovine bone (AC) in different proportions (75/25, 50/50, and 25/75) were used as catalysts in the photo-Fenton process to degrade methylene blue (MB) in aqueous solution. The materials were prepared by the citrate-nitrate sol-gel synthesis method and used as catalysts in the photo-Fenton process. The photocatalytic tests were performed in a cylindrical reactor with a 4.

This study presents the effect of natural zeolite (NZ) on a nitrifying sequencing batch reactor for removing ibuprofen (IBP) and diclofenac (DFC) in the long term, including kinetics and microbial community. The research was conducted in two 2 L liquid-volume bioreactors, one with 5 g/L of NZ. Nitrogen load rates ranging between 5.

In this study, ADM1-based kinetics were combined with a thermal model that accounts for various heat transfers inside and through the reactor's boundaries. Computing the energy of bioreactions based on kinetic rates prevented an overestimation of approximately 20% in the heat demand of the heat exchanger, compared to calculations using feedstock degradation heat. This also improved the representation of the digester's thermal and reactional inertia.

Large amounts of agri-food waste are generated and discarded annually, but they have the potential to become highly profitable sources of value-added compounds. Many of these are lignin-rich residues. Lignin, one of the most abundant biopolymers in nature, offers numerous possibilities as a raw material or renewable resource for the production of chemical products.
