Name: 3-Hydroxydihydrofuran-2(3H)-oneOn September 1, 2020 ,《Sorbitol electro-oxidation reaction on sub<10 nm PtAu bimetallic nanoparticles》 was published in Electrochimica Acta. The article was written by Torres-Pacheco, Luis J.; De Leon-Rodriguez, Antonio; Alvarez-Contreras, Lorena; Guerra-Balcazar, Minerva; Arjona, Noe. The article contains the following contents: Sorbitol is a highly available and functionalized polyalc., with vast industrial usages and with great potential for fuel cells application. However, few studies were done regarding its electrochem. oxidation Monometallic Au, Pt and PtAu with different compositions from Pt-rich (such as Pt85Au15) to Au-rich (Pt10Au90) nanomaterials were synthesized. Several parameters like sorbitol and KOH concentration, scan rate, charge-transfer resistance, and temperature were tested. According with the physicochem. characterization, average particle sizes from 5.6 to 6.5 nm were found for all electrocatalysts, while Pt at. percentages of 85, 60, 40, and 10% were obtained. XPS revealed shifts in Pt 4f and Au 4f core-levels related to electron d. changes by the interaction between these elements and as a result, the electrocatalytic properties for the sorbitol electrooxidation reaction (SOR) were modified. The PtAu nanomaterials presented an increase of the c.d. with the raise of the KOH and sorbitol concentrations, being Pt40Au60/C the most active electrocatalyst displaying 40 mA mg-1 at 0.1M sorbitol in 2 M KOH with an onset potential of -0.50 V vs. normal H electrode. This onset potential value was more neg. to that typically reported for other polyols like glycerol and ethylene glycol. The reaction pathway of Pt/C, Au/C and Pt40Au60/C was followed by chromatog. and spectroscopic techniques, finding that the complex surfaces of these electrocatalysts were capable to carry the SOR via several electrons (from 2 to 24 e-). In this manner, the high electrocatalytic activity of Pt40Au60/C was attributed to the electron d. changes that promote a higher electron transfer forming shorter-chain byproducts. In the part of experimental materials, we found many familiar compounds, such as 3-Hydroxydihydrofuran-2(3H)-one(cas: 19444-84-9Name: 3-Hydroxydihydrofuran-2(3H)-one)

Application of 19444-84-9On September 10, 2021 ,《Co-hydrothermal carbonization of swine and chicken manure: Influence of cross-interaction on hydrochar and liquid characteristics》 was published in Science of the Total Environment. The article was written by Li, Qingyin; Zhang, Shu; Gholizadeh, Mortaza; Hu, Xun; Yuan, Xiangzhou; Sarkar, Binoy; Vithanage, Meththika; Masek, Ondrej; Ok, Yong Sik. The article contains the following contents:

Swine and chicken manures are abundant solid wastes that can be converted into carbonaceous materials through hydrothermal carbonization (HTC). Owing to their unique biochem. compositions, co-HTC of these two types of manures may have significant implications for the generated products. We investigated the co-HTC of swine manure and chicken manure to understand the influence of the interaction between contrasting manures on the properties of the derived products. The results indicated that co-HTC treatment enhanced the formation of solid product and improved the C and N contents, heating value, and energy yield of the resulting hydrochar. Regarding the ignition temperature and comprehensive combustion index, the combustion properties of the hydrochar were enhanced owing to the mutual effect of the HTC intermediates. Addnl., the interaction of the intermediates significantly impacted the transfer of nitrogenous species and generation of organic acids and organic polymers with fused-ring structures. Therefore, co-HTC processing of animal manures could potentially provide a sustainable pathway for the conversion of animal waste into solid products with improved characteristics compared to those produced by treating the two feedstocks sep.

《Visible light-induced Minisci reaction through photoexcitation of surface Ti-peroxo species》 was published in Catalysis Science & Technology in 2021. These research results belong to Naniwa, Shimpei; Yamamoto, Akira; Yoshida, Hisao. Product Details of 19444-84-9 The article mentions the following:

Photocatalytic Minisci-type functionalization of pyridine with THF (THF) proceeded using hydrogen peroxide (H2O2) and a TiO2 photocatalyst under acidic conditions. Under UV light (λ = 360 nm), the reaction selectivity based on pyridine (Spy) was >99% while the selectivity based on THF (STHF) was low such as 19%. In contrast, under visible light (λ = 400 or 420 nm) Spy was similarly high (>99%) and STHF was two times higher than that under UV light. A surface peroxo complex formed upon contact of hydrogen peroxide with the TiO2 surface can be selectively photoexcited by visible light to inject the photoexcited electron to the conduction band of TiO2. The electron can reduce H2O2 to a reactive oxygen species (ROS) and promote selectively the Minisci-type cross-coupling reaction between pyridinium ions and THF. A reaction test with a hole scavenger (methanol) evidenced that the hole oxidation of H2O2 under UV light was responsible for the lower selectivity, in other words, the higher selectivity under visible light would be due to suppression of the hole oxidation of H2O2. These results demonstrate a novel way to improve the selectivity of the photocatalytic cross-coupling reaction by using H2O2 as an oxidant with the photoexcitation of surface Ti-peroxo species on TiO2.

The article was written by Condurso, Concetta; Cincotta, Fabrizio; Merlino, Maria; Stanton, Catherine; Verzera, Antonella. The article contains the following contents:

Powd. infant formula (PIF) and lactose-free PIF during secondary shelf-life (SSL) and under domestic practices was investigated to verify their stability up to the expiration date and under the label instructions for milk reconstitution. Particular attention was given to variations in Maillard reaction and lipid peroxidation products identified and quantified by HS-SPME-GC-MS. Two types of PIF: Type A based on bovine milk and Type B a lactose-free product based on glucose syrup were analyzed. The PIF were analyzed at regular time intervals beyond the labeled expiration date after opening, and reconstituted using water at 70°C, 80°C and 90°C. A large number of volatile compounds were identified and significant statistically differences resulted during SSL and water temperature used for reconstitution that were correlated to the PIF composition The study showed that water temperature for reconstitution of samples and the SSL has to be adapted to PIF composition3-Hydroxydihydrofuran-2(3H)-one(cas: 19444-84-9Computed Properties of C4H6O3) was used in this study.

Electric Literature of C4H6O3On October 11, 2019 ,《Non-targeted analysis of the particulate phase of heated tobacco product aerosol and cigarette mainstream tobacco smoke by thermal desorption comprehensive two-dimensional gas chromatography with dual flame ionisation and mass spectrometric detection》 was published in Journal of Chromatography A. The article was written by Savareear, Benjamin; Escobar-Arnanz, Juan; Brokl, Michal; Saxton, Malcolm J.; Wright, Chris; Liu, Chuan; Focant, Jean-Francois. The article contains the following contents:

An anal. methodol. based on thermal desorption and comprehensive two-dimensional gas chromatog. with dual time-of-flight mass spectrometry and flame ionization detection (TD-GC × GC-TOFMS/FID) was developed for non-target anal. of volatile organic compounds (VOCs). The technique was optimized for the measurement of the VOC content of the particulate phase (PP) fraction of aerosols produced by a tobacco heating product (THP1.0) and 3R4F mainstream tobacco smoke (MTS). The method involves sampling the PP fraction on quartz wool packed in a sorbent tube directly connected to machine-puffing, followed by a dilution through a TD recollection procedure over Tenax/Sulficarb sorbent before TD-GC × GC-TOFMS/FID anal. The comparison of the VOC content of the PP fraction of aerosols produced by THP1.0 and MTS highlighted the compositional difference between tobacco combustion (592 peaks) and tobacco heating process (160 peaks). Mass spectrometric signals were used for qual. analyses based on linear retention indexes, mass spectral matches, and GC × GC structured chromatograms, which collectively identified up to 90% of analytes detected in PP samples. FID signals were used for semi-quant. analyses based on a chem. class external calibration method. The global chem. composition of PP samples showed that hydrocarbons, oxygenated, and nitrogen-containing compounds were fewer in number and much less abundant in THP1.0 PP. Overall, 93 compounds were common to the two sample types. Excepted for a few highly volatile compounds (mainly furan family) as well as glycerin and its acetate, analyte concentrations were higher in MTS PP. The results came from multiple reactions, including the reaction of 3-Hydroxydihydrofuran-2(3H)-one(cas: 19444-84-9Electric Literature of C4H6O3)

The article was 《Electrochemically Enabled, Nickel-Catalyzed Dehydroxylative Cross-Coupling of Alcohols with Aryl Halides》. The article mentions the following:

As alcs. are ubiquitous throughout chem. science, this functional group represents a highly attractive starting material for forging new C-C bonds. Here, it is demonstrated that the combination of anodic preparation of alkoxy triphenylphosphonium ion and nickel catalyzed cathodic reductive cross-coupling provides an efficient method to construct C(sp2)-C(sp3) bonds, in which free alcs. and aryl bromides e.g., bromobenzene-both readily available chems. can be directly used as coupling partners yielding arene derivative e.g., I.

Computed Properties of C4H6O3On June 1, 2022, Wurzler, Gleicielle Tozzi; da Silva, Victor Teixeira; de Almeida Azevedo, Debora; Ana da Silva, Ayla Sant’; Noronha, Fabio Bellot published an article in Fuel Processing Technology. The article was 《Integrating bio-oil and carbohydrate valorization on the fractionation of sugarcane bagasse via Organosolv process using Mo2C-based catalysts》. The article mentions the following:

This work studied the fractionation of sugarcane bagasse via Organosolv treatment using isopropanol/water in the presence of Raney-Ni and molybdenum carbide catalysts (Bulk Mo2C and Mo2C supported on activated carbon (AC) or Al2O3). The degree of delignification, the bio-oil and solid residue composition depended on the type of catalyst. A partial extraction of hemicellulose occurred followed by depolymerization, resulting in a product distribution that depended on the catalyst. Raney-Ni catalyst promoted the formation of diols and triols, while xylose, furfural, and furan were mainly produced by Mo2C based-catalysts. The Organosolv treatment without catalyst and in the presence of bulk Mo2C produced a bio-oil containing mainly 2,3-dihydrobenzofuran. Mo2C/AC and Mo2C/Al2O3 are promising catalysts for the fractionation of sugarcane bagasse that produced a bio-oil with higher yield to substituted methoxyphenols and a solid residue more easily hydrolyzed by cellulases, producing higher yield to glucose than Raney-Ni catalyst.

《Fast Pyrolysis Oil Upgrading via HDO with Fe-Promoted Nb2O5-Supported Pd-Based Catalysts》 was published in Energies (Basel, Switzerland) in 2022. These research results belong to Campos Fraga, Mariana Myriam; Lacerda de Oliveira Campos, Bruno; Hendrawidjaja, Handoyo; Carriel Schmitt, Caroline; Raffelt, Klaus; Dahmen, Nicolaus. Electric Literature of C4H6O3 The article mentions the following:

Due to the high acid, oxygen and water contents of fast pyrolysis oil, it requires the improvement of its fuel properties by further upgrading, such as catalytic hydrodeoxygenation (HDO). In this study, Nb2O5 was evaluated as a support of Pd-based catalysts for HDO of fast pyrolysis oil. A Pd/SiO2 catalyst was used as a reference Addnl., the impact of iron as a promoter in two different loadings was investigated. The activity of the synthesized catalysts was evaluated in terms of H2 uptake and composition of the upgraded products (gas phase, upgraded oil and aqueous phase) through elemental anal., Karl Fischer titration, GC-MS/FID and 1H-NMR. In comparison to SiO2, due to its acid sites, Nb2O5 enhanced the catalyst activity toward hydrogenolysis and hydrogenation, confirmed by the increased water formation during HDO and a higher content of hydrogen and aliphatic protons in the upgraded oil. Consequently, the upgraded oil with Nb2O5 had a lower average mol. weight and was therefore less viscous than the oil obtained with SiO2. When applied as a promoter, Fe enhanced hydrogenation and hydrogenolysis, although it slightly decreased the acidity of the support, owing to its oxophilic nature, leading to the highest deoxygenation degree (42.5 weight%) and the highest product HHV (28.2 MJ/kg).

Computed Properties of C4H6O3On September 1, 2021 ,《Depsipeptide nucleic acids: Prebiotic formation, oligomerization, and self-assembly of a new proto-nucleic acid candidate》 was published in Journal of the American Chemical Society. The article was written by Fialho, David M.; Karunakaran, Suneesh C.; Greeson, Katherine W.; Martinez, Isaac; Schuster, Gary B.; Krishnamurthy, Ramanarayanan; Hud, Nicholas V.. The article contains the following contents:

The mechanism by which informational polymers first formed on the early earth is currently unknown. The RNA world hypothesis implies that RNA oligomers were produced prebiotically, before the emergence of enzymes, but the demonstration of such a process remains challenging. Alternatively, RNA may have been preceded by an earlier ancestral polymer, or proto-RNA, that had a greater propensity for self-assembly than RNA, with the eventual transition to functionally superior RNA being the result of chem. or biol. evolution. We report a new class of nucleic acid analog, depsipeptide nucleic acid (DepsiPNA), which displays several properties that are attractive as a candidate for proto-RNA. The monomers of depsipeptide nucleic acids can form under plausibly prebiotic conditions. These monomers oligomerize spontaneously when dried from aqueous solutions to form nucleobase-functionalized depsipeptides. Once formed, these DepsiPNA oligomers are capable of complementary self-assembly and are resistant to hydrolysis in the assembled state. These results suggest that the initial formation of primitive, self-assembling, informational polymers on the early earth may have been relatively facile if the constraints of an RNA-first scenario are relaxed. The experimental part of the paper was very detailed, including the reaction process of 3-Hydroxydihydrofuran-2(3H)-one(cas: 19444-84-9Computed Properties of C4H6O3)
