On November 30, 2021, Pasquini, Celio; Hespanhol, Maria C. published an article.Formula: C12H24O11 The title of the article was A rotational-linear sample probing device to improve the performance of compact near-infrared spectrophotometers. And the article contained the following:

A novel device to probe solid ground samples by simultaneous rotational and linear displacement of their container is described and evaluated. The device improves the representativeness of spectra obtained from laboratory samples measured by near-IR (NIR) spectroscopy using low-cost, compact instruments. These instruments typically illuminate and probe a small portion of the laboratory sample, affecting the quant. and qual. anal. results due to a lack of sample representativeness of the NIR spectrum. The device maximizes the sample amount assessed during the measurement, providing a more representative average spectrum. Principal component anal. of the spectral data was employed to evaluate and guide the minimization of the effect of sample heterogeneity on the anal. results. A significant improvement in the range 70 to 300% in the quant. multivariate regression results over less representative measurement modes was obtained by employing the new device and the rotational-linear mode. The experimental process involved the reaction of SweetPearlR P300 DC Maltitol(cas: 585-88-6).Formula: C12H24O11

On April 28, 2022, Du, Chuanshen; Andino, Richard S.; Rotondaro, Matthew C.; Devlin, Shane W.; Erramilli, Shyamsunder; Ziegler, Lawrence D.; Thuo, Martin M. published an article.Formula: C10H22S The title of the article was Substrate Roughness and Tilt Angle Dependence of Sum-Frequency Generation Odd-Even Effects in Self-Assembled Monolayers. And the article contained the following:

Role of substrate type, gold or silver, and surface roughness on the parity odd-even effect in n-alkanethiolate (n = 10-16) self-assembled monolayers (SAMs), materials of potential importance to mol. scale electronics, is studied using vibrational sum-frequency generation (SFG) spectroscopy. An inverted odd-even effect is observed for SAMs on Ag substrates relative to SAMs on Au. The metal-specific SFG spectra in the Me and methylene stretching regions provide a sensitive probe of the in situ cant angle and mol. twist dependence of the interfacial group orientation. Within the precision of these measurements, disorder due to gauche defects is not evident in this spectral anal. SFG Me vibrational frequencies and line widths show parity and substrate dependence. Metal substrate roughness, an under-reported exptl. parameter, affects the extent of odd-even Me orientation anisotropy. Parity-dependent Me orientation effects are seen on Ag beyond the roughness limit established by hydrophobicity data on Au. The SFG anal. predicts an ~2.8 nm rms roughness limit for odd-even effects on Ag substrates. These SFG results further confirm the role competing pairwise short-range dispersive (∝1/r6) and longer range polar (∝1/r to 1/r4) interactions play in controlling the observed odd-even wetting behavior of SAMs on metal substrates as a function of surface roughness. The experimental process involved the reaction of 1-Decanethiol(cas: 143-10-2).Formula: C10H22S

On June 4, 2020, Kap, Oezlem; Kabanov, Nikolai; Tsvetanova, Martina; Varlikli, Canan; Klavsyuk, Andrey L.; Zandvliet, Harold J. W.; Sotthewes, Kai published an article.Product Details of 143-10-2 The title of the article was Structural Stability of Physisorbed Air-Oxidized Decanethiols on Au(111). And the article contained the following:

We have studied the dynamic behavior of decanethiol and air-oxidized decanethiol self-assembled monolayers (SAMs) on Au(111) using time-resolved scanning tunneling microscopy at room temperature The air-oxidized decanethiols arrange in a lamellae-like structure leaving the herringbone reconstruction of the Au(111) surface intact, indicating a rather weak interaction between the mols. and the surface. Successive STM images show that the air-oxidized mols. are structurally more stable as compared to the nonoxidized decanethiol mols. This is further confirmed by performing current-time traces with the feedback loop disabled at different locations and at different mol. phases. D. function theory calculations reveal that the diffusion barrier of the physisorbed oxidized decanethiol mol. on Au(111) is about 100 meV higher than the diffusion barrier of a chemisorbed Au-decanethiol complex on Au(111). A two-dimensional activity map of individual current-time traces performed on the air-oxidized decanethiol phase reveals that all the dynamic events take place within the vacancy lines between the air-oxidized decanethiols. These results reveal that the oxidation of thiols provides a pathway to produce more robust and stable self-assembled monolayers at ambient conditions. The experimental process involved the reaction of 1-Decanethiol(cas: 143-10-2).Product Details of 143-10-2

On June 26, 2020, Ju, Jian; Hsieh, Chao-Mao; Tian, Yao; Kang, Jian; Chia, Ruining; Chang, Hao; Bai, Yanru; Xu, Chenjie; Wang, Xiaomeng; Liu, Quan published an article.Electric Literature of 143-10-2 The title of the article was Surface Enhanced Raman Spectroscopy Based Biosensor with a Microneedle Array for Minimally Invasive In Vivo Glucose Measurements. And the article contained the following:

To monitor blood glucose levels reliably, diabetic patients usually have to undergo frequent fingerstick tests to draw out fresh blood, which is painful and inconvenient with the potential risk of cross contamination especially when the lancet is reused or not properly sterilized. This work reports a novel surface-enhanced Raman spectroscopy (SERS) sensor for the in situ intradermal detection of glucose based on a low-cost poly(Me methacrylate) microneedle (PMMA MN) array. After incorporating 1-decanethiol (1-DT) onto the silver-coated array surface, the sensor was calibrated in the range of 0-20 mM in skin phantoms then tested for the in vivo quantification of glucose in a mouse model of streptozocin (STZ)-induced type I diabetes. The results showed that the functional poly(Me methacrylate) microneedle (F-PMMA MN) array was able to directly measure glucose in the interstitial fluid (ISF) in a few minutes and retain its structural integrity without swelling. The Clarke error grid anal. of measured data indicated that 93% of the data points lie in zones A and B. Moreover, the MN array exhibited minimal invasiveness to the skin as the skin recovered well without any noticeable adverse reaction in 10 min after measurements. With further improvement and proper validation, this polymeric MN array-based SERS biosensor has the potential to be used in painless glucose monitoring of diabetic patients in the future. The experimental process involved the reaction of 1-Decanethiol(cas: 143-10-2).Electric Literature of 143-10-2

On May 10, 2021, Yamaguchi, Sho; Fujita, Shu; Nakajima, Kiyotaka; Yamazoe, Seiji; Yamasaki, Jun; Mizugaki, Tomoo; Mitsudome, Takato published an article.Electric Literature of 585-88-6 The title of the article was Support-Boosted Nickel Phosphide Nanoalloy Catalysis in the Selective Hydrogenation of Maltose to Maltitol. And the article contained the following:

Metal phosphide catalysts have attracted attention for organic synthesis owing to their stability and high activity. Nevertheless, metal-support interactions and support-boosted metal phosphide catalysis remain unexplored. Herein, we report the development of a hydrotalcite (HT: Mg6Al2CO3(OH)16·4(H2O))-supported nickel phosphide nanoalloy (nano-Ni2P/HT) that exhibits high activity for the hydrogenation of maltose, which is an important reaction for producing maltitol as a sweetener and food additive. The HT support drastically increased the catalytic activity of nano-Ni2P, allowing nano-Ni2P/HT to outperform conventional catalysts. Various spectroscopic studies revealed that cooperative catalysis by nano-Ni2P and HT plays a key role in the efficient hydrogenation of maltose. The cooperative catalysis enabled high-yield production of maltitol, even at ambient temperature Furthermore, nano-Ni2P/HT was successfully recovered and reused while retaining its high activity and selectivity. Notably, nano-Ni2P/HT operated well in concentrated maltose solutions (>50 weight %), demonstrating that the high performance of this catalyst will pave the way for the efficient and sustainable production of maltitol. The experimental process involved the reaction of SweetPearlR P300 DC Maltitol(cas: 585-88-6).Electric Literature of 585-88-6

And the article contained the following:

The fruit of Rosa Roxburghii Tratt (RRT) is edible and has been considered as a medicinal fruit with a lipid-lowering effect, but the mechanism is still unclear. In this study, we integrated the results of 16S rRNA gene sequence and fecal metabolome to explore the potential mechanisms of RRTJ treatment in hyperlipidemia. The result suggests the useful effects of RRT juice (RRTJ) in hyperlipidemic rats. The 12 wk of RRT juice (RRTJ) treatment decreased serum lipids, fat accumulation, body weight and liver weight RRTJ treatment reversed the HFD-induced gut dysbiosis by lowering Dorea, Coprobacillus abundance and enriching Bifidobacterium, Roseburia abundance. Also, we conducted a targeted metabolic profile anal. of 160 metabolites in feces and 19 feces metabolites have significant changes. Correlation analyzes suggest that the reductions in serum lipids by RRTJ are associated with the gut microbial community (Dorea, Coprobacillus and Roseburia, Bifidobacterium) and their associated metabolites (palmitoleic acid, succinic acid, propionic acid, Glyceric acid). In conclusion, the 12 wk of treatment with RRT juice (RRTJ) can regulate dyslipidemia by improving intestinal microbiota disorders and related metabolites disorders. The experimental process involved the reaction of 2,3-Dihydroxypropanoic acid(cas: 473-81-4).Recommanded Product: 2,3-Dihydroxypropanoic acid

On November 1, 2022, Apriyanto, Ardha; Compart, Julia; Zimmermann, Vincent; Alseekh, Saleh; Fernie, Alisdair R.; Fettke, Joerg published an article.Computed Properties of 473-81-4 The title of the article was Indication that starch and sucrose are biomarkers for oil yield in oil palm (Elaeis guineensis Jacq.). And the article contained the following:

Oil palm (Elaeis guineensis Jacq.) is the most productive oil-producing crop per ha of land. The oil that accumulates in the mesocarp tissue of the fruit is the highest observed among fruit-producing plants. A comparative anal. between high-, medium-, and low-yielding oil palms, particularly during fruit development, revealed unique characteristics. Metabolomics anal. was able to distinguish accumulation patterns defining of the various developmental stages and oil yield. Interestingly, high- and medium-yielding oil palms exhibited substantially increased sucrose levels compared to low-yielding palms. In addition, parameters such as starch granule morphol., granule size, total starch content, and starch chain length distribution (CLD) differed significantly among the oil yield categories with a clear correlation between oil yield and various starch parameters. These results provide new insights into carbohydrate and starch metabolism for biosynthesis of oil palm fruits, indicating that starch and sucrose can be used as novel, easy-to-analyze, and reliable biomarker for oil yield. The experimental process involved the reaction of 2,3-Dihydroxypropanoic acid(cas: 473-81-4).Computed Properties of 473-81-4

Redruello-Requejo, Marina; Gonzalez-Rodriguez, Maria; de Lourdes Samaniego-Vaesken, Ma; Montero-Bravo, Ana; Partearroyo, Teresa; Varela-Moreiras, Gregorio published an article in 2021, the title of the article was Low-and no-calorie sweetener (LNCS) consumption patterns amongst the Spanish adult population.Product Details of 585-88-6 And the article contains the following content:

Low- and no-calorie sweeteners (LNCS) are a group of food additives characterized by their high sweetness intensity and virtually zero caloric content, attributes that make them potential substitutes for added sugars in processed foods and beverages. However, there is currently scarce information available about both the different LNCS used in food products available in Spain and their consumption patterns. Prompted by these reasons, the aim of this research work was to identify the presence and consumption of LNCS in food and beverages consumed by a representative sample of the Spanish adult population (n = 507). For this purpose, a Food Frequency Questionnaire was carried out. Overall, it was found that 4.5% of the foods and 22.3% of the beverages consumed by the surveyed population contained LNCS. The food groups that presented the highest percentage of daily servings containing LNCS were non-alc. beverages such as soft drinks and juices (36.1%); sugars and sweets such as chocolates, candies, or chewing gum (14.2%); milk and dairy products (7.0%); meat and derivative products (5.1%); cereals and derivatives (4.3%); appetizers (1.7%); and, finally, sauces and condiments such as ketchup or mustard (1.0%). The main LNCS consumed were acesulfame-K, sucralose, sorbitol, aspartame, and cyclamate, although their prevalence of use differs greatly among foods, beverages, or tabletop sweeteners. Our results show the great diversity of food groups that are currently including these compounds as ingredients. Consequently, there is a need for these food additives to be included in food composition databases, which should be regularly updated to include LNCS in order to facilitate their assessment and monitoring in dietary nutritional surveys. The experimental process involved the reaction of SweetPearlR P300 DC Maltitol(cas: 585-88-6).Product Details of 585-88-6
