Vacuum-Ultraviolet Absorption Spectrum of 3-Methoxyacrylonitrile

The high-resolution absorption spectrum of 3-methoxyacrylonitrile (3MAN) was measured between 5.27 and 12.59 eV using a synchrotron-based Fourier-transform spectrometer. It was related to an absolute absorption cross-section scale. Complementary calculations at the DFT-MRCl/aug-cc-pVTZ level of theory document the vertical transition energies and oscillator strengths toward the first 19 states of both the E and Z geometrical isomers of 3MAN. Comparisons with the experimental absorption spectrum reveal the similarities and differences between 3MAN, a bifunctional molecule, with acrylonitrile and methyl-vinylether, where only one functional group is present. As in acrylonitrile, several broad valence transitions were observed up to the ionization limit. They are likely associated with the extended pi-system induced by the nitrile group but might also involve sigma sigma* transitions close to the ionization limit. As in methylvinylether, Rydberg series converging to the ionization limit are absent. This is attributed to a difference in neutral and cationic geometry due to a 60 degrees rotation of the methyl group.

Porous fluorinated polyarylene ether nitrile as ultralow permittivity dielectrics used under humid environment

Dielectric materials demonstrating ultralow permittivity, excellent mechanical property and durability under humid environment are highly demanded for the rapid development of 5G communication systems. Herein, a series of porous fluorinated polyarylene ether nitrile (FPEN) films having ultralow permittivity and excellent mechanical property that can be used under moisture environment are prepared by a delayed phase inversion approach. Due to the introduction of low molar polarity fluorinated substituents and porous structures, the porous FPEN films show ultralow dielectric constant of lower than 1.40 at 1 kHz and hydrophobic surface with the water contact angle higher than 901. In addition, the porous FPEN films also exhibit an ultralow dielectric constant (<1.42 at 1 kHz) even when placed in a humid environment with a relative humidity of 80% for 72 h. The porous FPEN films demonstrate elongation at break higher than 32%, specific modulus higher than 1260 MPa cm(3) g(-1), excellent flexibility and foldability. These outstanding properties including the ultralow dielectric properties, hydrophobicity, flexibility, foldability and others facilitate the application of porous FPEN films as 5G communication system dielectrics. Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 38487-86-4.

Elevated CO2 improves glucosinolate metabolism and stimulates anticancer and anti-inflammatory properties of broccoli sprouts

Sprouting process enhances plant bioactive compounds. Broccoli (Brassica oleracea L) sprouts are well known for their high levels of glucosinolates (GLs), amino acids, and antioxidants, which offer outstanding biological activities with positive impacts on plant metabolism. Elevated CO2 (eCO(2), 620 ppm) was applied for 9 days to further improve nutritive and health-promoting values of three cultivars of broccoli sprouts i.e., Southern star, Prominence and Monotop. eCO(2) improved sprouts growth and induced GLs accumulation e.g., glucoraphanin, possibly through amino acids production e.g., high methionine and tryptophan. There were increases in myrosinase activity, which stimulated GLs hydrolysis to yield health-promoting sulforaphane. Interestingly, low levels of ineffective sulforaphane nitrile were detected and positively correlated with reduced epithiospecifier protein after eCO(2) treatment. High glucoraphanin and sulforaphane levels in eCO(2) treated sprouts improved the anticarcinogenic and anti-inflammatory properties of their extracts. In conclusion, eCO(2) treatment enriches broccoli sprouts with health-promoting metabolites and bioactivities.

Novel polyethersulfone dielectric films with high temperature resistance, intrinsic low dielectric constant and low dielectric loss

In this work, a series of fluorene-containing fluorinated polyethersulfone (PES-6AF/BHPF) copolymers with high temperature resistance and intrinsic low dielectric constant (low-epsilon) have been designed and synthesized from 4,4 ‘-dichlorophenyl sulfone (DCS) and polyphenol. The performance of obtained PES-6AF/BHPF can be controlled and optimized by controlling the copolymers structure. The thermal and dielectric properties of PES-6AF/BHPF were evaluated comprehensively. The obtained PES-6AF/BHPF copolymers show high glass transition temperatures (T-g) ranging from 200 to 260 degrees C, and 5% weight loss temperatures (T-d5%) is stable up to 500 degrees C. The epsilon value of PES-6AF/BHPF-0% and PES-6AF/BHPF-100% are as low as 2.1 and 2.3, and the loss tangent (tan delta) are only 0.0088 and 0.003 at 1 kHz, respectively. In addition, all of PES-6AF/BHPF films show good stability of dielectric properties in high temperature conditions. More importantly, the PES-6AF/BHPF copolymers are soluble in common solvents (such as DMAc, NMP, DMF, THF). The PES-6AF/BHPF copolymers are amorphous and can be easily cast into transparent and flexible films with tensile strength of 62-74 MPa and an elongation at break of 13.3-15.8%. The outstanding comprehensive properties made it possible to be the most promising polymer candidates for high-performance interlayer dielectrics.

Novel rare earth coordination polymers with greatly enhanced fluorescence by synergistic effect of carboxyl-functionalized poly(arylene ether nitrile) and 1,10-phenanthroline

A series of novel rare earth coordination polymers were synthesized using carboxyl-functionalized poly(arylene ether nitrile) (CPEN) as a macromolecular ligand, europium and terbium ions as central ions, and 1,10-phenanthroline (Phen) as a small-molecule coligand. The experimental results confirmed that the rare earth ions were simultaneously coordinated with the carboxyl groups of CPEN and Phen in the ternary coordination polymers. It was worth noting that the fluorescence intensity of the ternary coordination polymers was greatly enhanced by the synergistic coordination of CPEN and Phen, which benefited from the efficient energy transfer from CPEN and Phen ligands to rare earth ions. Furthermore, it was found that the fluorescence intensity increased with increasing Eu3+ ion content in ternary coordination polymer, and the critical Eu3+ ion concentration when fluorescence quenching occurred was as high as 11.5 wt%. As a result, the ternary coordination polymers exhibit intense, characteristic red (Eu3+) and green (Tb3+) emission under UV excitation both in the powder and film state. In addition, the rare earth coordination polymers showed a high glass transition temperature (251 degrees C) and high thermal stability, offering great potential applications as light-emitting devices, fluorescence detectors and sensors in special environments (e.g., high-temperature environment, extreme environments).

On the methylacetylene abundance and nitrogen isotope ratio in Pluto’s atmosphere

To bring our photochemical model of Pluto’s atmosphere and ionosphere (Krasnopolsky, 2020) into agreement with the recent detection of 5 x 10(15) cm(-2) methylacetylene C3H4 (Steffl et al., 2020), rate coefficients of the three key reactions of C3H4 production and loss have been changed to values calculated by (2019). This change reduces the abundance of cyanoacetylene HC3N close to the measured ALMA upper limit (Lellouch et al., 2017), increases the model abundances of H-2 and C3H8 by factors of 1.3, and reduces the abundances of H and C4H2 by factors of 1.3, while other species are changed less than 5% in the model. The predicted abundance of atomic hydrogen agrees with that derived from the observed Lyman-beta emission by Steffl et al. (2020). The observed (HCN)-N-14/(HCN)-N-15 > 125 on Pluto (Lellouch et al., 2017) looks puzzling compared to (HCN)-N-14/(HCN)-N-15 = 60 on Titan. Our analysis confirms the predissociation of N 2 at 80-100 nm as the main process of nitrogen isotope fractionation. The observed twofold difference is partially caused by the diffusive depletion of the heavy isotope in HCN and in the predissociation of N-2. On Pluto, the mean altitudes of HCN and predissociation of N-2 are 500 and 860 km, well above the homopause at 96 km. On Titan, observations of (HCN)-N-14/(HCN)-N-15 refer to 90-460 km (Vinatier et al., 2007), the predissociation occurs near 985 km, both below the homopause at 1000 km, and diffusive depletion does not occur. Therefore the observed limit corresponds to N-14/(15) N > 253 for N-2 in the lower atmosphere and N-14/N-15 > 228 in the upper layers of the N-2 ice. These limits reflect the conditions on Pluto in the last two million years, which is the lifetime of N-2 in Pluto’s atmosphere with the current N-2 loss of 37.5 g cm(-2) Byr(-1) primarily for photodestruction. The calculated isotope fractionation factor of 1.96 accounts for the formation and condensation of nitriles, diffusive separation, and fractionation in thermal escape. Variations of N-14/N-15 in the N-2 ice are related to the evolution of the solar EUV, mixing processes in the N-2 ice, and possible periods of hydrodynamic escape, which are poorly known and not considered here.

Synthesis and characterization of a crosslinked membrane based on sulfonated poly(aryl ether sulfone) and sulfonated polyvinyl alcohol applied in direct methanol fuel cells

Vinyl-terminated sulfonated poly (arylene ether sulfone) (VSPAES) and sulfonated polyvinyl alcohol containing vinyl group (VSPVA) have been prepared. The VSPVA and VSPAES were crosslinked by adding AIBN as initiator. The results of FT-IR and H-1-NMR indicated the existence of sulfonic acid groups and crosslinked structure in these crosslinked membranes. The microphase structures of the membranes are analyzed by SEM. The proton conductivities of membranes were above 10 mS cm(-1), which indicated that it basically meet the needs of fuel cells. The methanol permeability coefficients of CSPAES membrane is 2.8×10(-7) cm(2) s(-1), remarkably lower than neat SPAES (8.5×10(-7) cm(2) s(-1)) and Nafion117 (14.1×10(-7) cm(2) s(-1)). Moreover, the proton selecticity of CSPAES membrane is close to 2 times higher than that of Nafion 117 membrane. The crosslinked membrane showed better stability than the linear SPAES membrane.
