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.

Skull Fracture Patterns and Morphologies Among Fatal Motorcycle Traffic Accident Victims in Vietnam

We aim to describe morphological structures of skull fractures and relevant factors in motorcycle accident victims in Vietnam. This work represents a retrospective cross-sectional study based on forensic reports of fatal motorcycle accident victims. Between January 2013 and August 2019, a total of 226 fatal motorcycle accident patients with skull fracture diagnoses were enrolled. Linear and depressed fractures were the common patterns (46.0% and 37.2% of cases, respectively), whereas stellate (11.5%) fractures were rare. Fractures of the temporal bone (68.6% of cases) and basilar skull (60.6%) were the most common, whereas fractures of the parietal bone were the least common (9.7%). Two or more patterns of skull fracture were recorded in 25.5% of cases, and 2 or more fracture locations were recorded in 76.6% of cases. Fractures of the parietal bone were associated with victims not wearing a helmet. In addition, fractures of the basilar skull were more likely to occur among victims with alcohol consumption. We found the common pattern of skull fractures was linear and depressed fractures, and the common location of skull fractures was temporal and basilar bone. Further studies that include larger sample sizes and collect more information should be conducted to better understand relationships between skull fractures and related factors.

MoS2 doping by atomic layer deposition of high-k dielectrics using alcohol as process oxidants

We developed doping technique of transition metal dichalcogenides based on atomic layer deposition (ALD) of oxide thin films. In this study, we deposited ALD Al2O3 overlayer using various oxidant including iso-propyl alcohol (IPA) and ethanol and investigated the doping effects depending on the choice of oxidant for ALD process. The doping effects were investigated by the change in the performance of bottom-gated MoS2 field effect transistors. Experimental results indicate that Al2O3 overlayer deposited using IPA as ALD reactant produces more efficient n-type doping effect compared to ethanol. Moreover, doping was effectively controlled by modulating atomic layer deposition process. ALD process using effective oxidant material is expected to be practically used for realizing the fabrication of threshold voltage-controllable transistors or further applications such as diodes.

Visible-Light Promoted C-O Bond Formation with an Integrated Carbon Nitride-Nickel Heterogeneous Photocatalyst

Ni-deposited mesoporous graphitic carbon nitride (Ni-mpg-CNx) is introduced as an inexpensive, robust, easily synthesizable and recyclable material that functions as an integrated dual photocatalytic system. This material overcomes the need of expensive photosensitizers, organic ligands and additives as well as limitations of catalyst deactivation in the existing photo/Ni dual catalytic cross-coupling reactions. The dual catalytic Ni-mpg-CNx is demonstrated for C-O coupling between aryl halides and aliphatic alcohols under mild condition. The reaction affords the ether product in good-to-excellent yields (60-92 %) with broad substrate scope, including heteroaryl and aryl halides bearing electron-withdrawing, -donating and neutral groups. The heterogeneous Ni-mpg-CNx can be easily recovered from the reaction mixture and reused over multiple cycles without loss of activity. The findings highlight exciting opportunities for dual catalysis promoted by a fully heterogeneous system.

The contributions of everyday and major experiences of racial discrimination to current alcohol use and regular smoking in Black adults: Considering variation by demographic characteristics and family history

Background: Racial discrimination has consistently been linked to elevated alcohol use and smoking in Black adults, but the independent contributions of everyday and major experiences of discrimination have rarely been investigated. The present study aimed to identify variation in magnitude of the links between each type of racial discrimination with current frequency of alcohol use and regular smoking by demographic characteristics and family history of problem drinking/regular smoking in Black adults in the U.S. Methods: Data were drawn from 4462 adults (29.40% Afro Caribbean, 70.60% African American; 63.20% female) in a nationally representative sample of Black Americans. Logistic regression analyses were conducted to predict current frequency of alcohol use and regular smoking using the Everyday Discrimination Scale (EDS) and Major Experiences of Discrimination Scale (MEDS), testing for interactions with demographic characteristics and family history. Results: In the alcohol model, an EDS by education level interaction was observed: OR = 1.04 (CI:1.02-1.07) for < high school; OR = 0.95 (CI:0.92-0.98) for >= high school. MEDS was independently associated with alcohol use (OR = 1.11, CI:1.04-1.18). In the smoking model, EDS was associated with elevated risk (OR = 1.03, CI:1.01-1.04) and a MEDS by age cohort interaction was observed: OR = 1.24 (CL1.11-1.38) for Application In Synthesis of 2,2′-(Ethane-1,2-diylbis(oxy))diethanol.

Synthesis and characterization of Mg1(-x)Ni(x)Al(2)O(4) and their photocatalytic behaviors towards Congo red under UV light irradiation

In this paper, MgAl2O4 nanoparticles were synthesized by the Sol-gel auto combustion method and were doped with different concentrations of Ni2+ (x= 0, 0.1, 0.05, and 0.03). By this method, a novel photocatalyst which had better decolorization percentages of Congo red(compared) to MgAl2O4 was produced. The MgAl2O4 samples were calcinated at 1000 degrees C. The samples obtained were characterized by X-ray diffraction (XRD), SEM, FT-IR, EDX, and ICP-AES. The photocatalytic activity of MgAl2O4 samples were evaluated by UV-Vis spectroscopy and diffuse reflectance spectra (DRS) to confirm the performance rate of the photocatalyst. Also, the photocatalytic properties were investigated in the presence of UV light, certain amounts of photocatalysts, and Congo red dye. The best- obtained results of the photocatalytic activity among the prepared samples were Mg0.9Ni0.1Al2O4 because this photocatalyst had a removal conversion of 99.3 % of the dye after 90 min, which was better than other photocatalysts in similar conditions. Mg0.9Ni0.1Al2O4 was used as a photocatalyst five successfully times without any changes or loss of its high photocatalytic activity for this process. In this project, we used Ni2+ to dope MgAl2O4 nanoparticles. The results decolorization percentages of Congo red showed that Mg0.9Ni0.1Al2O4 had better efficiency compared to MgAl2O4, (and other) photocatalysts.

Ultrashort pulse laser at 1564.3 nm wavelength with E-beam deposited copper nanoparticles saturable absorber

The experimental investigation to explore the generated laser output by using newly developed copper nanoparticle (Cu-NP) as a saturable absorber (SA) at 1550 nm operating region is presented. Accordingly, the light-material interaction between copper nanoparticles and PolyVinyl-Alcohol (PVA) film interpreted onto the modulation depth of Cu-NP was recorded at about 36 (0.14)% wherein the laser ring cavity consists of all-fibre components that are compatible with the proposed operating window. A similar to 1.88 MHz passively soliton mode-locked at 1564.3 nm with pulse-width of 2.85 (0.16) ps and 7.95 (1.7) nJ of maximum pulse energy was successfully generated. Moreover, the high signal to noise ratio of 71 dB while maintaining long term stability as well as low threshold power suggests that the properties owned by pure copper nanoparticles as a great alternative towards conventional saturable absorber.

Validity and measurement invariance of the Addictions Neuroclinical Assessment incentive salience domain among treatment-seekers with alcohol use disorder

Incentive salience, or the attribution of motivational value to stimuli, is a biopsychological process that is disrupted in alcohol use disorder (AUD). The Addictions Neuroclinical Assessment (ANA) is a framework to characterize heterogeneity in addiction and establish a common assessment battery for research and clinical use. The ANA framework hypothesizes three constructs that correspond to processes in the etiology, course, and treatment of addiction: incentive salience, negative emotionality, and executive function. The current study extends prior findings on the ANA by validating the incentive salience construct among participants (n = 563) in a multisite prospective study of individuals entering treatment for AUD. We used confirmatory factor analysis to test a one-factor model of incentive salience. Indicators included items assessing perception of urges to drink from the Alcohol Dependence Scale, Impaired Control Scale, and Marlatt Relapse Interview. Results indicated the one-factor model fit the data well (chi(2) (12) = 19.42, p = .08; RMSEA = 0.034 [90% CI: 0.000, 0.060], CFI = 0.992) and was measurement invariant across sex. Incentive salience was associated with drinking patterns (e.g., drinks per day, r = 0.447 [95% CI: 0.379, 0.514]); reasons for drinking (urges/temptation r = 0.529 [95% CI: 0.460, 0.599]); testing personal control, r = 0.384 (95% CI: 0.308, 0.461); social pressure, r = 0.549 (95% CI: 0.481, 0.617); and family history of AUD, r = 0.134. The incentive salience factor demonstrated greater predictive validity for drinking outcomes compared to alternative preexisting scales. Overall, this study provides support for the construct validity and measurement invariance of the ANA incentive salience construct in a sample of individuals seeking AUD treatment.

Alkylation of a hydrophilic photosensitizer enhances the contact-dependent photo-induced oxidation of phospholipid membranes

Lipophilic photosensitizers able to photo-induce lipid oxidation in biomembranes are, in general, much more efficient than hydrophilic ones; acting through the formation of singlet oxygen (O-1(2)), which oxidizes the fatty acid double bonds (type II mechanism). Here we investigate the binding and photosensitizing properties of 4-(decyloxy)pteridin-2-amine (O-decyl-Ptr) using unilamellar vesicles of 1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC), a phospholipid with monounsaturated fatty acids. By means of molecular dynamic (MD) simulations, we showed that O-decyl-Ptr binds to the membrane in a localization that favors the direct reaction of the triplet excited state of O-decyl-Ptr with DOPC double bonds. As a consequence, although O-1(2) is formed, O-decyl-Ptr acts mainly as a contact-dependent photosensitizer, meaning through radical formation (type I mechanism). Mass spectrometry analysis of vesicles irradiated in the presence of O-decyl-Ptr, demonstrated the generation of alcohols (LOH), ketones (LO) and hydroperoxides (LOOH). In agreement with the mechanistic hypothesis proposed, LOH and LO (type I photooxidation products) are formed faster than LOOH (type II photooxidation product). Interestingly, no short-chain oxidized products were detected. Accordingly, membrane fluctuations and formation of filaments and buds are observed during in-situ photo-activation of O-decyl-Ptr in giant unilamellar vesicles due to changes in membrane spontaneous curvature. Finally, we evaluated the effect of the photochemical processes studied at a cellular level and demonstrated in experiments of viability of mammalian cells that O-decyl-Ptr has important photodynamic properties. Similar experiments performed using the hydrophilic photosenstizer pterin (Ptr) show that alkylation leads to a striking increase in the efficiency of photosensitized lipid oxidation.

Effect of Saccharomyces cerevisiae and Schizosaccharomyces pombe strains on chemical composition and sensory quality of ciders made from Finnish apple cultivars

Composition of volatile compounds and concentrations of sugars and organic acids were studied in apple ciders produced with Saccharomyces cerevisiae and Schizosaccharomyces pombe yeasts using eleven different Finnish apple cultivars. Moreover, sensory quality of selected ciders was studied using check-all-that-apply test with untrained panelists. Seventy-seven volatile compounds were detected in the samples using HS-SPME-GC-MS. In general, the ciders had higher concentrations of higher alcohols, aldehydes, and acetals whereas the juices contained higher contents of C6-alcohols. Simultaneously, fermentation using S. pombe resulted in lower concentrations of malic acid, ethyl pentanoate, ethyl hexanoate, and volatile acids and higher concentrations of residual sugars compared to S. cerevisiae. Ciders made using S. cerevisiae were characterized as ‘alcoholic’ and `yeasty’ while S. pombe ciders were more frequently described as ‘sweet’, ‘honey-like’, and less rated as sour. Besides the strong effect by the yeasts, apple cultivars had significant effects on the compositional and sensorial properties of apple ciders.
