Experimental insights of solvent polymeric matrix and electric field influence on dielectrophoretic assembling of MXene-based composites
(Elsevier, 2026-08-21) Țurcan, Ina; Filip, Tudor-Alexandru; Vlad-Bubulac, Tăchiță; Rusu, Daniela; Olariu, Marius Andrei
Harnessing the outstanding properties of MXenes in polymeric-based materials development requires careful consideration of their structural characteristics, as their organization coordinates composite’s functional performances. Herein, we investigate the electro-responsive behavior of Ti3C2Tx in both polar and non-polar solvents, including polyethylene glycol. Frequency-dependent effect of AC electro-osmotic flow (ACEO) and dielectrophoretic force was assessed, the first one being predominant at lower frequencies in low-conductivity media, while at 10 kHz and above, the diminishing electric double layer (EDL) response suppressed electrothermal effect (ETE) and enabled positive DEP (pDEP) which governed MXenes motion. Lower polyethylene glycol (PEG) concentrations facilitated MXenes rapid assembling as chains, while higher PEG levels suppressed alignment and delayed bridge formation. Time-resolved analysis indicates that MXenes assembling is governed by the concurrence of dielectrophoretic forces and PEG-mediated resistance. These findings highlight the interplay influence of electric field parameters, solvent types and matrix properties.

Field inhomogeneous distributions and local percolations in Ag-BaTiO3 ceramic-metal composites: The role of microstructural variability
(Elsevier, 2026-08-08) Țurcan, Ina; Pădurariu, Leontin; Lukacs, Vlad Alexandru; Știrbu, Radu-Ștefan; Ciomaga, Cristina Elena; Pătru, Roxana Elena; Chamasemani, Fereshteh Falah; Brunner, Roland; Stoian, George; Mitoșeriu, Liliana; Giuranno, Donatella
This work investigates how composition and microstructural variability influence the dielectric properties of xAg–(1–x)BaTiO3 ceramic-metal composites (denoted as CerMet) through combined modelling/experimental approach. Virtually generated microstructures predict different percolation ranges depending on microstructural modifications. To check such effect, a range of compositions with x ≤ 20 vol.% were synthesized using single-step or two-steps sintering to ensure compositional integrity and similar BaTiO3 grain size. During the consolidation, Ag undergoes melting, migration, and infiltration, generating intricate metal–ceramic connectivity. The permittivity exhibits percolation-like increases near critical compositions around 5, 11.5, and >20 vol.%, reaching a maximum value of εᵣ ≈ 17,000 at 20 °C with tan δ ≤ 2% (at 10 kHz) for x = 11.5 vol.%. The high permittivity compositions selected for X-Ray tomography and detailed microscopic analyses revealed 3D microstructures with specific features, where field concentration (“hot spots”) occurs. These results demonstrate how metal melting during sintering governs microstructural evolution and variability and the important role of the elongated and tortuous filler structures in increasing the CerMet effective permittivity towards giant values towards the percolation limits.

The effects of administering zeolites on growth performances in a juvenile carp polyculture (Cyprinus carpio) with silver carp (Hypophthalmichthys molitrix) and bighead carp (Hypophthalmichthys nobilis)
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2018) Nistor, Veta; Savin, C.; Tenciu, Magdalena; Mocanu, Elena-Eugenia; Eșanu, V.O.
Volcanic tuffs contain a type of minerals, called zeolites, that function as "molecular sifts" in the treatment of wastewater. This study evaluated the influence of zeolite administration on carp brood growth in the 1st summer, it increased in polyculture with Silver Carp and Bighead Carp. The results have shown that the use of zeolite has slightly influenced the soil and water quality and has resulted in a better assimilation of feed in basin B2 than in control B1. The overall growth rate was higher in B2 than in B1 (2.346 kg versus 2.226 kg). Biological material has grown normally, without the development of pathological conditions that could influence the conduct of the experiment. The physical-chemical parameters of the water, with few exceptions, fell within the optimal range for carp growth. Implementing this method of natural zeolite filtering would improve fish microclimate factors and increase the production of fish biomass and would obtain production increases in ecological conditions, and ensure the quality of technological water and stimulate better food assimilation. Trough the application of carp growth technology (Cyprinus carpio) in summer I in polyculture using zeolites involved the administration of organic fertilizers, the use of fodder as close to ecological standards as possible and the use of zeolites to ensure the quality of technological water as to stimulate better food assimilation The real growth gain in experiments had the highest value in B2 (conventional technology and zeolite utilization) with 2.346 kg / ha followed by B1 (conventional technology) with 2.226 kg / ha, indicating that the use of zeolite ensures both Physical-chemical parameters of the water but also contributes to a better assimilation of the food.

Research concerning the reproduction indeces at the romanian Black and White cows from the private farms situated in the north-east development area
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2018) Gîlcă, Ioan; Gîlcă, Valerica; Mihalache, Roxana-Georgiana; Avram, P.; Proboteanu, A.; Gîngă, C.; Ignat, Elena
Researches were done in a population of 300 cows Black and White breed grow into the private exploitation in the North East part of Romania. There were analyzed the following characters: the age of the first calving(V.P.); the calving-interval (C.I.); the inter-lactation period (R.M.); service period (S.P.). The mean values of breeding indices (VP, RM, CI and SP) highlight an inappropriate state of reproductive activity, with large differences from one holding to another and even within the same holding.

Whey recovery and nutraceutical products – preliminary data
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2018) Ahmadi, Mirela; Ciobanu, Fl.; Ciabrun, Isabella-Denisa; Tulcan, Camelia; Milovanov, Cornelia; Boldura, Oana-Maria; Mederle, Narcisa; Dronca, D.; Filimon, Nicoleta; Ivancia, Mihaela
Purpose of our work: This work proposed some fresh nutraceutical drinks based on whey resulted from milk processing technology. For this we collected fresh whey from a milk plant from Timis County and we prepared some beverages based on whey – as the majority ingredient. As secondary ingredients we used fresh pineapple, fresh kiwi, fresh ginger, powdered cinnamon, powdered anise, and in some products we add honey. Materials and methods: We proposed 4 different products with whey as a the majority ingredient: one beverage was prepared (blended) from whey, pineapple, and cinnamon; one with whey, pineapple, kiwi, and cinnamon; one with whey, pineapple, cinnamon, honey, ginger, and anise; and one prepared from whey, honey, and ginger. After 48 hours we analyzed the total content of lipids (Gerber method), acidity (Soxthlet-Henkel method), protein content (modified Steinegger method), dry matter and humidity (thermo-balance method). Results: The total content of lipids was 0.00% in fresh whey, and was very low in all prepared samples (0.2-0.4%); acidity was 3.8°T for whey and varied between 5.8-18.8°T in prepared samples– depending on the fruit content; total protein was registered as 1.64g/100g for whey, with variations between 1.55-2.52g/100g product; fresh whey had the highest water content (95.69%), with variations between 86.19-91.96 for our proposed whey-drinks. Conclusions: Whey is a valuable nutritional product that can be used for preparing fresh drinks with nutraceutical properties. Our preliminary data demonstrate that proposed drinks are very good for hydrating, being low in lipids and containing valuable and easy digesting proteins. Adding fresh pineapple, kiwi, ginger, honey and cinnamon to our products we improved the nutritive value of our products, especially by increasing the vitamins and minerals content. Also due to our ingredients we proposed four fresh nutraceutical products with very good antioxidant capacity.
