Edible Micro-Sized Composite Coating Applications on Post-Harvest Quality of Sweet Cherry Fruits

Horticulturae, Год журнала: 2025, Номер 11(3), С. 303 - 303

Опубликована: Март 11, 2025

Active packaging using an edible coating could be essential and sustainable alternative solution to preserve the properties of fruits prevent food loss waste. Fruits generate significant wastes losses. Reducing waste is a global priority. For this research, nature-based solutions (NBSs) were applied, micro-sized chitosan (CsMPs) selenium microparticles (SeMPs), which are green-synthesized from black tea leaf extracts, thyme oil. In study, effects new generation active preservative agents formed combinations oil (Oil) on quality “0900 Ziraat” sweet cherry after harvest investigated. After coated with colloid solution, they stored at 4 °C 21 for 20 days, parameter analyses performed days 0, 5, 10, 15, 20. As result it was determined that application CsMPs + SeMPs subsequent Oil coatings reduced weight loss, respiration, decay rates. Also, these applications most effective in preserving color values (L*, chroma, hue), fruit firmness, total soluble solid (TSS) amount, acidity content phenolics, anthocyanin, antioxidant capacity. These results show can used as extend their shelf life harvest. This study’s will contribute obtaining composite agents/agents produced technology life.

Evidence for two kinds of hydrogen-bonding networks in ionic solutions by 2D infrared correlation spectroscopy

Research Square (Research Square), Год журнала: 2025, Номер unknown

Опубликована: Март 28, 2025

IR spectra from 4000 to 100 cm^{− 1} were measured for four kinds of alkali chloride solutions (LiCl, NaCl, KCl, CsCl solutions) with different concentrations. Their second derivative revealed two bands around 3400 and 3160 attributed the OH stretching mode weakly hydrogen-bonded (WHB) strongly (SHB) water species, respectively. Two-dimensional correlation spectroscopy (2D-COS) was applied analyze spectra. Two autopeaks in a 2D synchronous spectrum correspond WHB SHB bands, Moreover, 2D-COS confirmed existence 700 350 1000 − region. The at are assignable liberational L2 modes correlated (~ 1) band 1), respectively, by hetero spectrum. These results suggest hydrogen-bonding networks constructed or species solutions.

Techno-economic assessment of effervescent tablet-based nanofluids

PLoS ONE, Год журнала: 2025, Номер 20(4), С. e0319265 - e0319265

Опубликована: Апрель 3, 2025

The techno-economics of producing effervescent tablet-based nanofluids in start-up industries was investigated. thermophysical properties, equipment costs, consumables, and operational expenditures for the production methods were determined. Electrical costs running devices assessed based on lowest, average, highest prices worldwide. Key financial metrics, including accumulated project cost, interest, annual operating expenses, payback discounted periods, internal rate return (IRR) calculated different interest rates amounts sold products. thermal performance under laminar turbulent flow conditions cost effectiveness results showed that nanofluid more favourable than its conventional counterpart. This is because lower tablet process compared to significant influence product both types projects. had a minimal impact previous cases. In addition, outperformed counterpart terms period, IRR, performance, making it an optimal choice investors decision-makers.

This study conducted a systematic and comparative investigation on how boiling storage affect the water quality of tap water, spring bottled focusing molecular cluster size, hardness, nitrite content, pH value. The findings revealed that reduces hardness size clusters in both with these effects lasting for several days. Boiling also decreases but after one day storage, levels boiled tend to rebound higher than those un-boiled water. However, stored closed bottle maintained lower up seven slightly increased values its effect could last There were correlative changes value due boiling. These results suggest is beneficial drinking because it can improve healthy drinking. Additionally, less year remains safe drink as does not significantly decline period.

Heterogeneity of ultrasonic wave properties in ex vivo cortical bone of racehorse

The Journal of the Acoustical Society of America, Год журнала: 2025, Номер 157(5), С. 3771 - 3779

Опубликована: Май 1, 2025

Despite the prevalence of lower limb disease in racehorses, outdoor bone evaluation equipment is lacking. Consequently, a secure and cost-effective field screening system for bones required to identify early-stage leg illness. Elastic stiffness cannot be measured using x-ray techniques closely associated with quality, which recognized as significant determinant fracture risk. Quantitative ultrasound has garnered attention viable option, offering insights into elastic stiffness. Understanding characteristic behaviors ultrasonic wave properties (velocity, attenuation, characteristics) crucial developing quantitative simulations plays role clinical evaluation. This study experimentally assessed thoroughbred utilizing an pulse technique megahertz range, ex vivo specimens. The exhibited uniaxial anisotropy demonstrated clear heterogeneity axial cross section. Exact measurements distinct bone. Elevated velocities were observed medial lateral regions, demonstrating significance. Attenuation was more pronounced core suggesting reliance on porosity. A correlation (R = 0.68, p < 0.001) found between velocity attenuation dense may attributable matrix properties.
