A novel gas flow-through photocatalytic reactor based on copper-functionalized nanomembranes for the photoreduction of CO2 to C1-C2 carboxylic acids and C1-C3 alcohols

A novel concept of gas flow-through photo(electro)catalytic reactor based on copper-functionalized nanomembranes for the conversion of CO2 is presented. The nanomembranes are based on aligned TiO2 nanotube arrays grown over a microperforated metallic substrate, acting as an electron collector and to provide the necessary robustness, which are then functionalized by copper oxide (Cu2O or CuO) electrodeposition. For comparison, the behavior of copper oxide electrodeposited over the bare microperforated metallic substrate is also given. The concept is quite different from conventional photocatalytic approaches. Due to the peculiar characteristics and conditions in the photoreactor (working under a cross-flow of gaseous CO2 saturated with water passing through the nanomembrane photocatalyst layer), it is possible to evidence for the first time the highly selective CO2 conversion to C1-C2 carboxylic acids (formic, acetic and oxalic acids) without formation of H-2, CO, CH4 or other hydrocarbons. Copper-oxide introduces an additional reaction pathway to C1-C3 alcohols (methanol, ethanol and isopropanol) or derived products (methyl formate). The best performances are obtained with p-type Cu2O over n-type TiO2 nanotubes (Faradaic Efficiency -FE- = 42% to methanol and 44% to acetic acid) due to the creation of a p-n-type heterojunction that improves visible light harvesting, giving an apparent quantum yield (ratio between electrons reacted and photons absorbed) with solar illumination of about 21%. FE up to 47% to methanol or 73% to acetic acid are observed among the other tested samples. The relevance of these results to the mechanism of CO2 conversion is also discussed.

A new insight of lignin pyrolysis mechanism based on functional group evolutions of solid char

To elucidate the mechanism of biomass lignin pyrolysis, the functional group evolution in lignin chars derived at 200-600 degrees C was investigated using two-dimensional perturbation correlation infrared spectroscopy, associated with the properties of the volatile products. Results from 2D-PCIS pointed that the change in the alcohol groups C-OH occurs earlier than that in the carbonyl groups C=O before 250 degrees C, corresponding to the reaction of keto-enol tautomerization: C-OH -> C=O, and the cleavage of bonds and remodeling reactions of the side chains of the benzene rings are synchronous. Besides, the formation of simple substituted benzene structures was earlier than complex substituted benzene structures. Decarbonylation, dehydrogenation and dealkylation were intensified during polycondensation of benzene rings. These findings are significant for achieving an in-depth understanding of lignin pyrolysis.

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 148043-73-6. Product Details of 148043-73-6.

Nanoimprint assisted free standing porous vanadium oxide nanosheet based ammonia sensor

Artificial intelligence in healthcare sector endures a largest share in non-invasive and point-of-care disease diagnosis by interfacing human behaviour through wearable pathway. In a view to develop sensing element for wearables, the concept of free standing poly-1-lactic acid (PLLA)/V2O5 nanosheets using sacrificial layer – (poly vinyl alcohol- PVA)method has been proposed in this work and the studies on ammonia (NH3) sensing has been briefly discussed. In a view to enhance the sensing performance of vanadium pentoxide (V2O5) film, surface modified PLLA substrates using nanoimprint lithography (NIL) have been implemented. The V+5 stoichiometry of the free standing PLLA/V2O5 films were confirmed using x-ray photoelectron spectroscopy (XPS). From field emission scanning electron microscopy (FE-SEM), it was observed that the patterned structure of about similar to 250 nm diameter was uniformly distributed on the surface of PLLA/V2O5 film. The chemiresistive sensing studies proved that the sensor response of V2O5 films on patterned PLLA substrate exhibited enhanced response about similar to 17 towards 75 ppm than the V2O5 film on unpatterned PLLA substrate. We believe that this strategy of patterned free standing PLLA/V2O5 nanosheets will help in fabricating the wearable sensors with better sensing performance.

An experimental assessment on low temperature combustion using diesel/ biodiesel/C2, C5 alcohol blends in a diesel engine

Alcohol additives in Diesel-Biodiesel (DB) blends were investigated on a modified single cylinder diesel engine with exhaust gas recirculation (EGR). The effects of lower and higher alcohol contents (10% ethanol, 20% ethanol and 10% pentanol by volume) with various EGR rates on combustion characteristics and emissions were evaluated. The results indicated that with the increase of EGR rates and increasing fraction of ethanol in DB blends, the ratio of premixed combustion will increase and the ignition delay (ID) will prolong, which lead to the increase of maximum pressure rise rate and peak value of heat release rate. Indicated thermal efficiency (ITE) increased firstly with EGR increasing and then decreased rapidly, but the EGR rates corresponding to the rapid decrease of ITE for the blends will be low compared to pure diesel. The Diesel-Biodiesel-Ethanol (DBE, the lower alcohol) blends showed the best performance on soot emissions among all the tested fuels even though there is no EGR. What’s more, the DBE blends showed better nitrogen oxide (NOx) and carbon monoxide (CO) emissions at high EGR. However, the Diesel-Biodiesel-Pentanol (DBP, the higher alcohol) blends performed better THC emissions. Overall consideration, using diesel/biodiesel/ethanol ternary fuels under medium EGR rates may be a better choice for diesel engines.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 42822-86-6 is helpful to your research. COA of Formula: C10H20O2.

Volatile compounds sorption during the aging of Chinese Liquor (Baijiu) using Pottery Powder

Pottery jar is the preferred storage vessel for aging baijiu, Chinese liquor, and it could sorb liquor micro-compounds. The objective of this work was to identify the sorption of liquor micro-compounds onto pottery powder, and gained insights regarding the sorption processes and mechanism. The sorption of liquor micro-compounds onto pottery powder of different sizes was studied using different kinetic models. The results showed that the sorption capacity varied among particle size of pottery powder, which also affected equilibrium time. The sorption process could be well described by the pseudo-second-order model, and the external diffusion was the rate-limiting step. Liquor volatiles in pottery powder at equilibrium were characterized, which detected alcohols, esters, acids, and furan by gas chromatography-mass spectrometry (GC-MS). These findings demonstrated pottery could not only cause subtractive changes that occur to liquor during the aging period, but also as a vector for transferring aromas sorbed when reused.

Highly Thermal-Resistant and Biodegradable Textile Sizes from Glycols Modified Soy Proteins for Remediation of Textile Effluents

Poly(vinyl alcohol) (PVA) sizes are widely used in textile industry due to their excellent sizing properties on synthetic fibers and their blends. However, PVA contains non-biodegradable chemicals and is a major contributor to environmental pollution related to the textile industry. To overcome this problem, an environmental-benign and highly thermal-resistant yarn coating is fabricated from soy proteins, an agricultural byproduct. The soy proteins are chemically modified by glycols having varying chain lengths and number of hydroxyl groups. Compared with the physically modified soy proteins and their sized yarns, coating made from the soy proteins esterified by 1,4-butanediol show 91.38% increment in work of rupture at 120 degrees C and cotton/polyester (65/35) yarns sized by 1,4-butanediol esterified soy protein sizes have 39.91% decrease in coefficient of friction. In addition, 1,4-butanediol esterified soy sizes have a five-day biochemical oxygen demand/chemical oxygen demand of 0.476, indicating that the chemically modified soy sizes have high biodegradability in activated sludge. Successful utilization of modified soy sizes can promote large-quantity applications of soy byproducts, impelling high value addition to agricultural byproducts and sustainability of textile industry.

Disaccharide anthocyanin delphinidin 3-O-sambubioside from Hibiscus sabdariffa L.: Candida antarctica lipase B-catalyzed fatty acid acylation and study of its color properties

Enzymatic lipophilization is an important process to extend the use of anthocyanins in lipidic media. In this work delphinidin 3-O-sambubioside (Dp3sam) isolated from Hibiscus sabdariffa L. flower was esterified with octanoic acid using Candida antarctica lipase B. The physical-chemical properties of the new lipophilic pigment were studied by UV-vis spectroscopy. Dp3sam with chloride, acetate and formate as counter ions were employed to study the lipophilization reaction. The hydrolysis of the reagent was avoided with a formate counter ion and the expected product was achieved with a noteworthy change of solubility. 1D and 2D NMR characterization of Dp3sam-C8 confirmed that the lipophilization took place at the primary alcohol of the glucoside moiety. Overall, the Dp3sam-C8 ester presents a stabilization of the quinoidal base (blue color) at neutral or moderate alkaline pH, which foresees a potential use of this pigment as a broad kind of industries on lipo-soluble formulations.

Enhanced flux and fouling resistance forward osmosis membrane based on a hydrogel/MOF hybrid selective layer

Although forward osmosis (FO) technology has been widely adopted for water treatment, it still faces great challenges, including low permeability and fouling problem. Herein, a novel forward osmosis membrane was developed with a stable, uniform and defect-free polyvinyl alcohol/polydopamine coated zeolitic imidazolate framework (PVA/PDA@ZIF-8) hybrid selective layer to simultaneously enhance its transport property and fouling resistance. The prepared FO membrane exhibits improved water flux without losing the selectivity, since the PDA@ZIF-8 provide additional preferential passageway for water transporting while hinder the diffusion of salt. The optimized membrane shows a higher water flux than pristine PVA membrane (14.2 vs. 8.7 L m(-2) h(-1) in FO mode, 24.3 vs. 14.8 L m(-2) h(-1) in PRO mode) with a reasonable selectivity considering as J(s)/J(w) value (0.44 vs. 0.4 g L-1 in FO mode, 0.38 vs. 0.33 g L-1). Moreover, the dynamic fouling experiments with organic foulants (protein and polysaccharide) indicate that the prepared membrane exhibits strong antifouling property and excellent permeation recovery ability (>95.0%) due to the optimized surface property. This study opens a new avenue for treatment wastewater by developing a forward osmosis membrane based on a hydrogel/MOF hybrid selective layer. (C) 2020 Elsevier Inc. All rights reserved.

Preventing E-cigarette use among high-risk adolescents: A trauma-informed prevention approach

Exposure to childhood trauma increases the risk of tobacco use during adolescence. Recent studies have also reported potentially increased vulnerabilities to electronic cigarette (e-cigarette) use among youth with a history of childhood trauma. While empirical evidence supporting the relationship between childhood trauma and adolescent e-cigarette use is emerging, few effective preventive interventions are available to curb e-cigarette use among adolescent victims of childhood trauma. This article reviews current evidence with respect to how childhood trauma could increase risk for nicotine dependence and e-cigarette use in adolescent populations. Furthermore, this paper describes the development, design, and implementation of Rise Above (RA), a randomized, controlled trial of a trauma-informed, e-cigarette preventive intervention. Lessons learned are also discussed, including the challenges of implementing evidence-informed prevention work within communities vulnerable to traumatic events.

An efficacy trial of adaptive interventions for alcohol use disorder

Background: Adaptive interventions, sometimes referred to as stepped care, are those interventions in which the type or dosage of treatment offered to patients is tailored to baseline clinical presentation and then adjusted over time in response to patient progress or lack thereof. Currently, no adaptive brief interventions exist specifically for alcohol use disorder (AUD). Method: This study used a sequential multiple assignment randomized trial design with 160 individuals with AUD recruited both locally and nationally who had a goal to reduce or abstain from drinking. Participants received brief advice (BA) and then the study reassessed them three weeks later; the study randomized those who did not respond to BA, defined as reducing their drinking to low-risk guidelines, to two session of motivational interviewing (MI) or more BA. The study then reassessed participants at week 8. The study re-randomized non-responders to receive either MI alone or MI plus behavioral self-control therapy (BSCT), also referred to as coping skills therapy, and evaluated participants at week 13. Results: Overall, participants receiving any BSCT made the greatest reductions in drinking. Participants who received MI at week 4 and BSCT at week 8 outperformed all other groups. Conclusion: Findings reveal that prolonged treatment, more sessions, and/or a specific combination of MI and BSCT provided optimal outcomes. Future research should determine whether such an algorithm holds across heterogenous groups of individuals with AUD.
