Investigating the effect of freezing method, voltage gradient, and probe type on quality characteristics of Turkey meat during the ohmic thawing process.

This research addresses the gap in efficient thawing methods by investigating the effects of ohmic thawing variables and freezing methods on the thawing speed and quality attributes of ground turkey breast, aiming to identify the optimal ohmic thawing method and compare it with traditional air and water thawing techniques. The variables for ohmic thawing consisted of voltage gradient (10, 15, and 20 V/cm), freezing method (Snap (rapid freezing of samples in liquid nitrogen at -210 °C), -70, and -20 °C), and probe type. The results showed that the snap-freezing method demonstrated superior functional and quality characteristics.

Exogenous dopamine application ameliorates chilling injury and preserves quality of kiwifruit during cold storage.

This study investigated the mechanisms employed by exogenous dopamine application in alleviating chilling injury in kiwifruits during storage at 1 °C for 120 days. Our results indicated that dopamine treatment at 150 µM alleviated chilling injury in kiwifruits during storage at 1 °C for 120 days. By 150 µM dopamine application, higher SUMO E3 ligase (SIZ1) and target of rapamycin (TOR) genes expression accompanied by lower poly(ADP-Ribose) polymerase 1 (PARP1) and sucrose non-fermenting 1-related kinase 1 (SnRK1) genes expression was associated with higher salicylic acid, ATP, NADPH and proline accumulation in kiwifruits during storage at 1 °C for 120 days.

High-Efficiency (21.4%) Carbon Perovskite Solar Cells via Cathode Interface Engineering by using CuPc Hole-Transporting Layers.

Carbon perovskite solar cells (C-PSCs) represent a promising photovoltaic technology that addresses the long-term operating stability needed to compete with commercial Si solar cells. However, the poor interface contacts between the carbon electrode and the perovskite result in a gap between C-PSC's performances and state-of-the-art PSCs based on metallic back electrodes. In this work, Cu (II) phthalocyanine (CuPc) was rediscovered as an effective hole-transporting material (HTM) to be coupled with carbon electrodes.

A Quantum Chemistry Insight into the Potential Role of the Singlet Oxygen-Acetone System as a Source for Production of Stable Secondary Organic Aerosols through a Multiwell Multipath Reaction.

The high abundance of acetone ((CH)C═O), which makes it a good candidate for oxygenated molecules, and the high reactivity of oxygen atoms in the first excited state O(D) are two well-known facts in the chemistry of the atmosphere. In this research, we prove that the singlet oxygen and acetone system is capable of proceeding through multiwell multipath reactions, leading to the production of several organic aerosols. Hence, the nature of species released by the (CH)C═O + O(D) reaction to air can be clarified by profound attention to the possible routes.

Effect of Balangu seed mucilage/gelatin coating containing dill essential oil and ZnO nanoparticles on sweet cherry quality during cold storage.

The current research focused on examining the effect of a coating made from Balangu seed mucilage (TSM-BM) and gelatin (Ge), with varying concentrations of dill essential oil (DEO) (0 %, 1 %, and 2 %) and zinc oxide nanoparticles (ZnO-np) (0 % and 0.5 %), on the quality characteristics of cherries stored at 4 °C over intervals of 0, 4, 7, 11, 18, and 25 days. The study noted that the application of this coating, particularly when combined with DEO and ZnO-np, significantly reduced the rate of changes in several parameters, including weight loss, firmness, titratable acidity, pH, total soluble solids, ascorbic acid, total anthocyanin content, total phenolic content, and antioxidant activity (p˂0.

Dopant-Free Spiro-OMe Imidazole-Based Hole-Transporting Material for Stable and Low-Cost Organic-Inorganic Perovskite Solar Cell.

The engineering of charge transport materials, with electronic characteristics that result in effective charge extraction and transport dynamics, is pivotal for the realization of efficient perovskite solar cells (PSCs). Herein, we elucidate the critical role of terminal substituent methoxy groups (-OCH) on the bandgap tuning of the spiro-like hole transport materials (HTMs) to realize performant and cost-effective PSCs. By considering spiro-OMeTAD as the benchmark HTM, we kept the backbone of spiro while replacing diphenylamine with phenanthrenimidazole.

Dissection of X chromosome dosage compensation for quantitative traits in sheep using different statistical models.

Since males and females have different number of X chromosome, different mechanisms have evolved to equalize dosage of gene products from the X chromosome between XX females and XY males. The aim of this study was to study X chromosome dosage compensation for growth rate (GR), Kleiber ratio (KR), efficiency of growth (EF) and relative growth rate (RGR) in Zandi sheep. A two steps procedure was adopted to analysis data.

Influence of Klein edges on Phononic and electronic transport in circular graphene devices.

We study the electron and phonon transport coefficients of graphene disks and rings in the presence of Klein edges. We examine the transport characteristics by changing of the outer and inner radius using the non-equilibrium Green's function approach. We find that the effect of the nanodisk radius is highly influenced by the Klein edges, such that at small radii, armchair Klein edges can help preserve the electronic transport coefficient from suppression, while zigzag Klein edges significantly suppress the transmission spectrum, highlighting the importance of the edge atom sublattice.
