Germination enriched lignans and sterols but lowered the oil ALA proportion. • A 13-week flaxseed oil dietary intervention with flaxseed oil was conducted in mice. • Most tissue n-3 fatty acid measures showed no significant GFO-UGFO differences. Germination can enrich bioactive components in flaxseed oil, but its effects on tissue lipid profiles remain unclear. This study examined changes in oil composition and tissue lipid responses to germinated flaxseed oil (GFO). Mice received soybean oil, ungerminated flaxseed oil (UGFO), or GFO for 13 weeks. Adipose tissue and red blood cell fatty acid profiles and brain lipidomics were assessed. GFO contained 1.3 times the sterol content and 3.4 times the lignan content of UGFO, but its alpha-linolenic acid (C18:3n-3, ALA) proportion was lower (53.35% versus 57.17%). Most measured tissue n-3 fatty acid outcomes showed no significant differences between GFO and UGFO. Brain lipidomics revealed differences in several EPA- and DHA-containing species relative to soybean oil controls. Our findings characterize the tissue lipid responses to UGFO and GFO, and provides a basis for optimizing germination through a balance between ALA retention and minor component enrichment.

All-solid-state lithium batteries have great potential applying to the fields of transportation and portable devices because of their high safety and energy density as the power source. As a critical component of device, solid-state electrolyte has been paid much attention. Given the excellent physical and chemical stability, Li 1+ x Al x Ti 2- x (PO 4 ) 3 (LATP)-based electrolyte has been considered as one of the most promising electrolytes for the next generation batteries. However, a further promotion of its ionic conductivity becomes extremely difficult, originating mainly from the poor connection of grains and a low relative density of LATP. Here, the nanosized and homogenous LATP ( x = 0.3) powders were synthesized through reducing the agglomeration of precursor powders and preparing at low temperatures. It is revealed that uniformly superfine LATP powders are able to improve the microstructure of grain boundaries during the pellet sintering process, thereby reducing the grain boundary resistance. Furthermore, as-synthesized nanosized powders mixed with Bi 2 O 3 additive present a better enhancement on the connection of grains and the relative density in LATP. On the basis of this understanding, we prepared LATP electrolytes with 0.5 wt% Bi 2 O 3 exhibiting a high ionic conductivity of 8.56 × 10 −4 S/cm, a high relative density of 94.4 % and a low activation energy of 0.27 eV, which is demonstrated as a prospective electrolyte in all-solid-state lithium battery LiFePO 4 /PEO/LATP/PEO/Li.

In this study, NaMg 1- x Mn x (PO 3 ) 3 (0.00 ≤ x ≤ 0.0625) ceramics with low dielectric constant were prepared via the solid-state reaction method. The effects of Mn 2+ substitution on the microstructure and dielectric properties (at microwave and terahertz frequencies) of the NaMg(PO 3 ) 3 ceramics were studied by means of the Rietveld refinement, morphology, and ionic polarizability analysis. It is obtained that the NaMg 0.0975 Mn 0.025 (PO 3 ) 3 ceramic sintered at 880 °C for 4 h exhibited optimal dielectric properties at microwave frequencies, where ε r = 4.585, Q × f = 48,313 GHz (@17.228 GHz), and τ f = −40.83 ppm/°C. The Q × f and τ f values were changed by 74.2 % and 27.8 %, as compared to the values of 27,728 GHz and −56.52 ppm/°C for the pure NaMg(PO 3 ) 3 ceramic, respectively. For terahertz frequencies (0.2–1.0 THz), the ε r values were decreased to 3.79–3.98, and the tan δ values were between 0.0203 and 0.1152. All the experimental results indicate that this system exhibits great potentials both at microwave and terahertz frequencies.

Auxin (Indole-3-acetic acid, IAA) is essential for anther development and male fertility, but little is known about its homeostasis in developing anthers due to its complex and diverse synthesis pathways. Here, we employed transcriptomic, targeted metabolomic, and amino acid analyses on a wild type (WT) cotton ( Gossypium hirsutum ) line SD98–6 and its nearly-isogenic male sterile (MS) line SD98–6A, to delve into the relationship between IAA and anther fertility. In WT anthers, IAA homeostasis was achieved mainly through self-synthesis, conjugate hydrolysis, and polar transport, and accumulation of IAA exhibited an inverted "U" pattern with the highest content observed at the tetrad stage. In MS anthers, no IAA accumulation was observed after the meiosis stage and the IAA content remained constantly low, mainly due to reduction of the substrates (phenylalanine and tryptophan) for IAA synthesis, and significantly decreased expression of the genes involved in IAA synthesis. Meanwhile, carbohydrate metabolism pathways directly contributing to IAA synthesis and synthesis of amino acids were malfunctional in MS anthers based on the expression profile of the metabolic genes and content measurement. These results provide valuable insights into the IAA homeostasis in cotton anthers and imply that genes related to IAA homeostasis are potential targets for development of IAA-sensitive male sterile cotton lines.

Ultra-low temperature sintered ceramics, Li 2 (Mg 1− x Ca x ) 2 (MoO 4 ) 3 ( x = 0.025–0.100), were synthesized using the solid-phase method. XRD analysis revealed that adding Ca 2+ increased the second-phase CaMoO 4 content. Particularly, Li 2 (Mg 0.975 Ca 0.025 ) 2 (MoO 4 ) 3 ceramics exhibited excellent properties: ε r = 9.31, Q × f = 55,400 GHz, and τ f = −38.9 ppm/°C. Incorporating Ca 2+ significantly improved the performance of ceramics. The microwave dielectric properties of Li 2 (Mg 0.9 Ca 0.1 ) 2 (MoO 4 ) 3 ceramics sintered at 650°C showed enhancements: ε r of 9.55, Q × f of 63,500 GHz, and τ f of −10.8 ppm/°C. The rise in ε r can be attributed to polarizability, while a higher packing fraction led to a larger Q × f value, and the reduced distortion of the [Li/Mg/CaO 6 ] octahedra enhanced the τ f value. Moreover, the increased of CaMoO 4 also positively influenced the ceramic's properties. Furthermore, in accordance with the principles of complex chemical bonding, the elevation of ionicity, lattice energy, and bond energy of the Mo–O bond contributed to the enhancement of ε r , Q × f , and τ f , respectively. Raman spectroscopy showed a positive correlation between dielectric loss and full width at half maximum of the Raman peak. Good chemical compatibility between silver and Li 2 (Mg 0.9 Ca 0.1 ) 2 (MoO 4 ) 3 ceramic was demonstrated through our co-firing experiment.

A novel xPb(Ni1/3Nb2/3)O3–(1-x)(0.30BiScO3–0.70PbTiO3) (PNN–BS–PT) ternary system was prepared by the columbite precursor method. The phase structure, microstructure, and electrical properties of ceramics of this system were investigated to identify the morphotropic phase boundary (MPB) composition of this system. The MPB with coexisting rhombohedral–tetragonal phases of PNN–BS–PT was located at approximately x=0.35, confirmed by their respective electric properties. With increasing PNN content, the coercive field EC, the Curie temperature TC, and the rhombohedral-to-tetragonal phase transition temperature TR–T were found to decrease and showed nearly linear dependences on their compositions. The enhanced properties were achieved in the MPB composition with x=0.35, which are as follows: dielectric constant εr=3160 (1 kHz), piezoelectric coefficient d33=490 pC/N, and electromechanical coupling factor kp=0.44. In addition, a large bipolar strain on the order of 0.6% was achieved for the composition when an electrical field E=40 kV/cm was applied.

A palladium catalyzed selective B(3)–H activation/oxidative dehydrogenative coupling for the synthesis of bis(o-carborane)s connected with B(3)–B(3′) and B(3)–B(6′) bonds has been developed for the first time. A plausible mechanism involving stepwise activation of B(3)–H and B(3′/6′)–H bonds by PdII and PdIV was proposed. This work is the first example and the most efficient protocol for synthesis of bis(o-carborane)s connected with B(3)–B(3′) and B(3)–B(6′) bonds, which has important reference for design, synthesis, and application of bis(o-carborane)s in related fields.

A Suzuki–Miyaura coupling reaction was performed to synthesize 5,15- meso -bis(2-chlorothiophen-3-yl)porphyrins in order to obtain a building block for further functional porphyrins. Photophysical and electrochemical properties were investigated to understand the effect of 2-chloro substituted thiophenes which are connected at their 3-position to the meso -position of the porphyrin. A computational calculation with counterpoise method was demonstrated to estimate the relative intermolecular interaction in order to compare solubility. Installed chloro atoms at the 2-position of thiophen-3-yl decreased in intermolecular interaction which caused an increase in solubility.

The effects of dairy sterilization techniques (65 °C/30 min, 72 °C/15 s, 85 °C/15 s, 100 °C/5 min, and 121 °C/5 s) on the epigallocatechin-3-gallate-casein (EGCG-CS) complexes were investigated through the structural and functional characteristics in this work. Fourier transform infrared spectroscopy (FT-IR) detection showed the r edshirting of the absorption peak suggested structural changes in the amide I area. Field emission scanning electron microscopy (FESEM) and viscosity measurements proved that treatments above 85 °C broke non-covalent bonds, leading to instability and low viscosity of EGCG-CS. Moreover, the values of surface hydrophobicity, solubility, and sulfhydryl group content appeared the same phenomenon of first rising then falling at higher temperatures, resulting from the CS protein exhibited obvious peptide chain stretch and hydrophobic residue exposure. Notably, the 15-s thermal treatment at 85 °C enhanced the structural stability, foaming, and emulsifying abilities of the EGCG-CS complexes, providing important technology information for industrial applications.

Pristine and Br-doped H2N = CHNH2Pb(I1−xBrx)3 (FAPb(I1−xBrx)3, Br content x = 0, 0.05, 0.15, 0.2, 0.3, and 0.4) films were prepared. The effect of Br-doping on phase stability, defect density, and performance of FAPb(I1−xBrx)3 was investigated by x-ray diffraction (XRD), scanning electron microscopy, ultraviolet–visible–near infrared absorbance spectroscopy, x-ray photoemission spectroscopy (XPS), Kelvin probe force microscopy (KPFM), positron annihilation spectroscopy, and current density–voltage (J–V) characteristics. The XRD measurements exhibit the enhancement of perovskite phase stability at x = 0.05. However, the phase stability decreases gradually with Br content (x) over 0.05. The increase of Br-doping content leads to the downshifting of both valence band (VB) position (indicated by XPS) and Fermi level (illustrated by KPFM). The energy level shifts are most probably due to the increase of Br 4p orbital content in VB and the change of self-doping levels. Doppler broadening spectra of positron annihilation radiation of the samples reveal that, the defect densities of Br-doped samples are much lower than that of pristine FAPbI3. For FAPb(I0.95Br0.05)3 sample, a high photoelectric conversion efficiency of 17.12% (25.7% higher than that of undoped sample) is successfully achieved. The significant enhancement of photoelectric conversion efficiency realized by Br-doping is attributed to the improvement of morphology, high phase stability, and low defect densities.

The molecular imprinting technique is powerful to prepare functional materials with molecular recognition properties. In this work, a potentiometric sensor was fabricated by dispersing molecularly imprinted polymers (MIPs) into plasticized PVC matrix and used for the determination of 1-hexyl-3-methylimidazolium cation ([C 6 mim] + ) in aqueous solution. The MIPs were synthesized by precipitation polymerization using 1-hexyl-3-methylimidazolium chloride ([C 6 mim]Cl) as the template molecule, methacrylic acid (MAA) and ethylene glycol dimethacrylat (EGDMA) as the functional monomers, and EGDMA also as the cross-linking agent. The as-prepared electrode exhibited a Nernstian response (58.87 ± 0.3 mV per decade) to [C 6 mim] + in a concentration range from 1.0 × 10 −6 to 0.1 mol kg −1 with a low detection limit of 2.8 × 10 −7 mol kg −1 , high selectivity, and little pH influence. The as-prepared electrode was used for the detection of the [C 6 mim] + in distilled water, tap water, and river water with a good recovery. It was also successfully applied in the determination of mean activity coefficients of [C 6 mim]Br in fructose + water systems based on the potentiometric method at 298.15 K.
