Insight into the potential of M-NbS (M = Pd, Ti and V) monolayers as anode materials for alkali ion (Li/Na/K) batteries.

Doping engineering significantly improves the electrochemical characteristics of electrode materials in alkali ion batteries. Herein, first-principles calculations were performed to systematically explore the effects of metal atom doping in NbS monolayers by substituting the Nb atoms with metal M atoms (M = Pd, Ti and V) on the structural stability and electrochemical performances. The results demonstrate that M-NbS monolayers can exhibit superior characteristics, including outstanding mechanical flexibility, excellent electronic conductivity, fast charge-discharge rate, low open circuit voltage and high theoretical capacity for alkali ion (Li, Na, and K) storage.

An LLTO-containing heterogeneous composite electrolyte with a stable interface for solid-state lithium metal batteries.

The interaction between LiLaTiO (LLTO) and metallic lithium leads to severe interfacial instability of LLTO-containing solid-state electrolytes with a lithium metal anode. To improve the interfacial stability, a heterogeneous composite electrolyte PVDF-HFP@LLTO/PEO (PLTP) is designed and fabricated with a PEO electrolyte layer adhered to the PVDF-HFP@LLTO (PLT) electrolyte membrane. The PLTP heterogeneous composite electrolyte exhibits a superior ionic conductivity of 3.

The chromatin remodeling protein BPTF mediates cell cycle, proliferation and apoptosis in porcine ovarian granulosa cells.

Bromodomain PHD finger transcription factor (BPTF), a core subunit of nucleosome-remodeling factor (NURF) complex, plays an important role in chromatin remodeling. However, few information of BPTF is available in pig, especially in mammalian follicular granulosa cells (GCs). The present study firstly confirmed that BPTF in porcine was relative close to human and mouse.

Epigenetic Iinsights into the Senescence of Porcine Fetal Fibroblasts induced by Passaging.

Epigenetic status of fetal fibroblasts (FFs) is one of the crucial factors accounted for the success of somatic cell nuclear transfer and gene editing, which might inevitably be affected by passaging. But few systematic studies have been performed on the epigenetic status of passaged aging cells. Therefore, FFs from large white pig were passaged to the 5, 10, and 15 (F5, F10, and F15) passages in the present study to investigate the potential alteration of epigenetic status.

Halide-driven polymorph selectivity in the synthesis of MnX (X = S, Se) nanoparticles.

Devising synthetic strategies to control crystal structure is of great importance as materials properties are governed by structure. MnS is a great model system as it has three known stable polymorphs. Herein, we show the selective synthesis of colloidal wurtzite- and rock-salt-type MnS under identical reactions conditions changing only the manganese halide precursor.

Astaxanthin alleviates palmitic acid-induced hindrance of porcine oocyte maturation.

Increased palmitic acid (PA) levels have been found in females with reduced fertility due to metabolic disorders. However, effective antioxidant astaxanthin (AXE) might positively affect animal reproduction. Therefore, the present study was designed to evaluate the impact of a high concentration of PA on oocyte maturation and the possible protective effect of AXE against high PA concentration in pigs.

Optimal Stage for Cryotop Vitrification of Porcine Embryos.

Different development stages of porcine embryos have different tolerance to low temperature. Therefore, we took the porcine embryos after parthenogenetic activation (PA) as the model, to explore the optimal development stage for vitrification during morula (D4), early blastocyst (D5), and expanded blastocyst (D6) after PA (D0). Embryos were observed with microscope and analyzed by different staining after cryo-recovery for 24 hours.

Division behaviours and their effects on pre-implantation development of pig embryos.

The quality of pre-implantation embryos could affect developmental efficiency after embryo transfer. However, the assessment of pre-implantation embryos was unsatisfactory, especially in pig embryos to date. Therefore, this study was designed to investigate available and applicable parameters that indicate developmental potential and quality of porcine pre-implantation embryos produced by handmade cloning (HMC), and parthenogenetic activation without zona pellucida (PAZF) and with zona pellucida (PAZI).

Microsphere-Like SiO /MXene Hybrid Material Enabling High Performance Anode for Lithium Ion Batteries.

To address the non-negligible volume expansion and the inherent poor electronic conductivity of silica (SiO ) material, microsphere-like SiO /MXene hybrid material is designed and successfully synthesized through the combination of the Stöber method and spray drying. The SiO nanoparticles are firmly anchored on the laminated MXene by the bonding effect, which boosts the structural stability during the long-term cycling process. The MXene matrix not only possesses high elasticity to buffer the volume variation of SiO nanoparticles, but also promotes the transfer of electrons and lithium ions.

Electrochemical Properties of the LiNiCoMnO Cathode Material Modified by Lithium Tungstate under High Voltage.

An amount (5 wt %) of lithium tungstate (LiWO) as an additive significantly improves the cycle and rate performances of the LiNiCoMnO electrode at the cutoff voltage of 4.6 V. The 5 wt % LiWO-mixed LiNiCoMnO electrode delivers a reversible capacity of 199.
