AB  - An emerging technology of active packaging enables prolongation of food shelf life by limiting the oxygen transfer and the reactivity of free radicals, which both destruct food freshness. In this work, Fe2TiO5 nanoparticles were synthesized using a modified sol–gel method and evaluated as an enforcement of alginate food packaging film. Pure phase Fe2TiO5 nanoparticles had an average particle size of 44 nm and rhombohedral morphology. Fe2TiO5 nanoparticles induce no cell damage of human Caco-2 epithelial cells and show no inhibitory effect towards growth of a panel of bacterial strains, suggesting good biocompatibility. Films obtained by incorporation of Fe2TiO5 nanoparticles into alginate using the solvent casting method show no migration of iron or titanium ions from films to food simulants again suggesting their safety as a packaging material. Fe2TiO5 nanoparticles also showed strong antioxidant efficiency as determined using the DPPḢ assay, and confirmed further in a preservation test on fresh fruit.

AB  - Silicon (Si) is considered a beneficial element for plants, mostly accumulating in cell walls, where its location and content are primed by the chemistry and structure of lignin. It is unrevealed how Si interacts with the process of lignin formation in the CWs. We studied, in an in vitro system, the interaction of SiO2 with the peroxidase-catalyzed polymerization of a lignin monomer into the lignin model compound, imitating conditions of the last step of lignin formation. FTIR and fluorescence spectroscopy and microscopy showed that Si is bound to the final polymer, and the structure of the Si-DHP differs from pure DHP. Fluorescence spectroscopy showed that Si does not bind to the monomers, so Si probably inhibits the formation of the larger lignin fragments, as evidenced by HPLC-DAD, by binding to dimmers formed during DHP synthesis. The structural changes of the polymer are related to the changed proportion of the fractions of various MW. The enzyme catalyzing DHP synthesis was not inhibited by Si. HRP activity was increased in presence of Si except for 6 mM Si. This may indicate that the complex formed with Si and short oligomers activates the enzyme, and prevents the formation of the large fragments.

AB  - In this paper the effect of accelerated carbonation process on the effectiveness of immobilization of cesium
(simulated radioactive and toxic waste) in the alkali-activated blast furnace slag (AABFS) matrix was studied. Blast
furnace slag (BFS) was contaminated with 2% and 5% Cs (with respect to the dry BFS mass) and alkali-activated with
sodium silicate solution, while the AABFS samples were cured sealed in plastic envelopes for 24 h at 95oC. First series of
AABFS samples were exposed to accelerated carbonation (open curing), while the second (reference) series of AABFS
samples left to aging (also sealed) at room temperature until testing. Thereafter AABFS samples were subjected to a
short-term (five-day) leaching tests according to the ANSI/ANS-16.1-2003 standard. The strength of AABFS mortars were
tested according to the SRPS EN 196-1 standard, while the carbonation was confirmed by phenolphthalein test and SEM
analysis. The diffusion coefficient (D) and non-dimensional leachability index (L) of cesium leached from AABFS were
calculated according to the ANSI/ANS-16.1–2003 standard. A correlation between the accelerated carbonation process
and the effectiveness of immobilization of cesium in AABFS was established.

AB  - This investigation was aimed to develop films and coatings based on natural biopolymers and active components, with physicochemical and functional properties for application in antimicrobial packaging. Biopolymer films were obtained from emulsions and dispersions by casting method. Coatings were formed by the application of emulsions on existing packaging. Synthesis of emulsions and dispersions were performed by combining biopolymers (chitosan-gelatin, pectin-gelatin) with lemongrass essential oil (LEO), Zn(CH3COO)2.2H2O, or ZnO, as active components. Fourier transform infrared (FTIR) spectra of the films showed that the addition of glycerol contributed to the forming of strong hydrogen bonds between glycerol and chitosan-gelatin or pectin-gelatin composites, facilitating the process of polymer branching, which is substantial for encapsulation. Thermal analyses revealed two characteristic processes occurring at 110 degrees C (water evaporation) and within 215-235 degrees C (degradation of polysaccharide and glycerol). Major weight losses were observed at 290 degrees C (chitosan-gelatin films) and 215 degrees C (pectin-gelatin films). The chitosan-gelatin films exhibited a lower degree of solubility (31-21%), and better mechanical properties comparing with the pectin-gelatin films. The chitosan-gelatin emulsions and dispersions exhibited a higher antibacterial effect in vitro against E. coli, B. subtilis, and S. aureus. In the case of the pectin-gelatin emulsions, the impact of LEO on the antibacterial activity was evident. The effects of biopolymer coatings on the development of microorganisms on fresh raspberries (Rubus idaeus L.) were performed in vivo during eight days of raspberry storage at refrigerator temperature. The tested coatings extended the shelf life of stored raspberries from four to eight days. The synergistic effect between LEO and ZnO or Zn-Ac was observed both in vivo and in vitro.

AB  - Alkali-activated binders (AABs), as a promising alternative to Portland cement, are now being used on a commercial scale in various applications around the world, including hazardous and radioactive waste immobilization. In this paper, the leaching resistance, strength, and nanostructural alteration of alkali-activated blast furnace slag (AABFS) doped with 2 % and 5 % cesium were investigated. The addition of cesium caused a significant increase in the compressive strength of AABFS, followed by mild strength reduction after leaching. AABFS can be considered a potentially efficient matrix for cesium immobilization, since the mean leachability index in both cases (2 % and 5 % of Cs added) was above the threshold value of 6. Both doping with Cs and leaching caused the transformation of the AABFS nanostructure. The majority of the aluminum that was released from the C-A-S-H gel due to leaching remained within the AABFS matrix, initiating gel reconstruction: the C-A-S-H gel was converted to C-S-H gel, and an additional N-(C)-A-S-H gel was also formed. Cesium was preferentially associated with the N-(C)-A-S-H gel rather than with the C-A-S-H gel. The results of this research seem to be in good agreement with the Cross-linked Substituted Tobermorite Model (CSTM).

AB  - Leaching is a phenomenon of fundamental interest in low-level radioactive waste disposal, and the
measurement of the leaching resistance of different wasteforms is very important for proper waste
management. In general, alkali-activated binders (AABs) can be considered as a sustainable solution
for safe immobilization of hazardous wastes containing different toxic or radioactive elements.
In this paper, the leaching resistance of AAB based on blast furnace slag (BFS), contaminated with 2%
cesium (i.e., solidified simulated low-level radioactive waste), was investigated according to the
ANSI/ANS-16.1-2003 standard procedure.
Based on the leaching results obtained for different elements, in particular for Cs, Si, Al, Ca, Na, and
K, it was concluded that the short (up to 5 days) semi-dynamic process of leaching from AAB can be
divided into two distinct stages: a) fast leaching of non-bound or loosely bound ions during the initial 24
hours, which occurred mostly between the surface of AAB and the leachant, and b) slower leaching in
the later stages of the experiment, which was controlled by diffusion of ions through AAB matrix.
By calculating the diffusion coefficient (D) and the leachability index (L) of cesium, it was also
concluded that AAB based on blast furnace slag, synthesized under the given experimental conditions,
can be considered as a potentially efficient matrix for immobilizing up to 2% cesium in hazardous

abstract = "Leaching is a phenomenon of fundamental interest in low-level radioactive waste disposal, and the
measurement of the leaching resistance of different wasteforms is very important for proper waste
management. In general, alkali-activated binders (AABs) can be considered as a sustainable solution
for safe immobilization of hazardous wastes containing different toxic or radioactive elements.
In this paper, the leaching resistance of AAB based on blast furnace slag (BFS), contaminated with 2%
cesium (i.e., solidified simulated low-level radioactive waste), was investigated according to the
ANSI/ANS-16.1-2003 standard procedure.
Based on the leaching results obtained for different elements, in particular for Cs, Si, Al, Ca, Na, and
K, it was concluded that the short (up to 5 days) semi-dynamic process of leaching from AAB can be
divided into two distinct stages: a) fast leaching of non-bound or loosely bound ions during the initial 24
hours, which occurred mostly between the surface of AAB and the leachant, and b) slower leaching in
the later stages of the experiment, which was controlled by diffusion of ions through AAB matrix.
By calculating the diffusion coefficient (D) and the leachability index (L) of cesium, it was also
concluded that AAB based on blast furnace slag, synthesized under the given experimental conditions,
can be considered as a potentially efficient matrix for immobilizing up to 2% cesium in hazardous
wastes.",

AB  - Geopolymers are a type of alkali activated binders,
inorganic aluminosilicate polymers with amorphous cross-linked
structure. Fly-ash is produced in abundance during coal firing,
and poses an environmental and health risk in untreated powder
form. Fly-ash geopolymer presents a sustainable alternative to
Portland cement, due to lower net greenhouse gas emissions.
Presence of naturally occurring radioactive elements in fly-ash is
one of the factors taken into account when estimating the safety
of fly-ash based building materials. Radon, a radioactive noble
gas originating from the decay of radium, can leave the material
and contribute to internal dose in closed spaces, so radon
exhalation is of special interest. Radon exhalation for a standard
sample of fly-ash geopolymer mortar was measured.
