Gholamipour-Shirazi, Azarmidokht published the artcileDesigning hydrocolloid based food-ink formulations for extrusion 3D printing, HPLC of Formula: 64519-82-0, the main research area is food grade hydrocolloid paste ink elasticity 3D printing.

Cold extrusion 3D food printing is an emerging technol. which enables the manufacture of food in different shapes and structures and offers huge potential for personalised food products. This study investigates rheol. properties and printability (shape fidelity) of food-grade hydrocolloid pastes. From this study, it was found that if the phase angle is in the range of 3°-15° and the relaxation exponent is in the range of 0.03-0.13 the paste material is printable, which means that it can support its own-weight if printed. As the demand for inks for 3D printing increases, rheol. measurements can rapidly assist with the development of new ink feedstocks.

Kosakivska, Iryna V. published the artcileMolecular mechanisms of plant adaptive responses to heavy metals stress, Application of (S)-2-hydroxysuccinic acid, the main research area is review plant adaptive response heavy metal stress; heavy metals; micronutrients; pollutants; redistribution; transport.

Heavy metals (HMs) are among the main environmental pollutants that can enter the soil, water bodies, and the atm. as a result of natural processes (weathering of rocks, volcanic activity), and also as a result of human activities (mining, metallurgical and chem. industries, transport, application of mineral fertilizers). Plants counteract the HMs stresses through morphol. and physiol. adaptations, which are imparted through well-coordinated mol. mechanisms. New approaches, which include transcriptomics, genomics, proteomics, and metabolomics analyses, have opened the paths to understand such complex networks. This review sheds light on mol. mechanisms included in plant adaptive and defense responses during metal stress. It is focused on the entry of HMs into plants, its transport and accumulation, effects on the main physiol. processes, gene expressions included in plant adaptive and defense responses during HM stress. Anal. of new data allowed the authors to conclude that the most important mechanism of HM tolerance is extracellular and intracellular HM sequestration. Organic anions (malate, oxalate, etc.) provide extracellular sequestration of HM ions. Intracellular HM sequestration depends not only on a direct binding mechanism with different polymers (pectin, lignin, cellulose, hemicellulose, etc.) or organic anions but also on the action of cellular receptors and transmembrane transporters. We focused on the functioning chloroplasts, mitochondria, and the Golgi complex under HM stress. The currently known mol. mechanisms of plant tolerance to the toxic effects of HMs are analyzed.

Lee, A. published the artcileThe comparative gastrointestinal responses of children and adults following consumption of sweets formulated with sucrose, isomalt and lycasin HBC, Name: (3R,4R,5R)-6-(((2S,3R,4S,5S,6R)-3,4,5-Trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexane-1,2,3,4,5-pentaol, the main research area is sucrose isomalt lycasin gastrointestinal tract child.

OBJECTIVES: To determine the gastrointestinal responses of children and adults following consumption of sucrose, isomalt and lycasin HBC and to compare these at two different dose levels in adults. DESIGN: Both studies were randomised, double-blind, cross-over designs. SUBJECTS: Fifty-one children aged 6-9 y were recruited from primary schools in the Salford area of Greater Manchester. Forty-eight children completed the study. Fifty healthy adult volunteers aged 18-24 yr were recruited from the student population of the University of Salford. All subjects completed the study. INTERVENTIONS: Children consumed either 25 g of sucrose, isomalt or lycasin HBC and adults 25 and 40 g in hard boiled sweets per day for two consecutive test days. Test periods of 2 days were separated by 7 day washout periods. Children consumed sweets throughout test days and adults in no less than 30 min but no more than 90 min. Subjects reported the prevalence and magnitude of flatulence, borborygmi, bloating, colic, bowel movements and watery faeces. RESULTS: Consumption of 25 g isomalt provoked a mild laxative effect in children but not in adults. Consumption of 25 g isomalt significantly increased the prevalence and magnitude of gastrointestinal responses in both children and adults. Consumption of 25 g lycasin HBC significantly increased borborygml in children and adults but no other gastrointestinal responses. Consumption of 40 g lycasin HBC or isomalt by adults significantly increased the mean frequency of bowel movements and the number of subjects passing watery faeces. In adults, 40 g isomalt and lycasin HBC provoked significantly more gastrointestinal responses compared to 25 g of either product. CONCLUSIONS: Consumption of 25 g lycasin HBC does not provoke an unacceptable laxative effect or gastrointestinal response in children or adults compared to 25 g isomalt, which is associated with a mild laxative effect and increase in gastrointestinal responses. In adults gastrointestinal responses following consumption of products were found to be dose dependent. SPONSORSHIP: Roquette Freres, Lestrem, France.

de Souza, Mandy published the artcileWater activated healing of thiolene boronic ester coatings, Category: alcohols-buliding-blocks, the main research area is thiolene boronic ester coating water activated healing.

A vinyl Ph boronic ester (VPBE) was synthesized and cured with pentaerythritol tetrakis(3-mercaptoptopionate) (PTMP) and 3,6-dioxa-1,8-octanedithiol (DODT) to produce boronic ester polymer networks. The reversible nature of the boronic ester linkage in water provides an opportunity to investigate their intrinsic healing for a variety of crosslink densities and healing conditions. The boronic ester networks prepared here, all had sub-ambient glass transition temperatures (Tg) and therefore enhanced mol. mobility at room temperature and above. Intrinsic healing of the different networks is investigated after making scratches on the polymer surface and observing behavior in humid environments, underwater and a hot dry environment. Underwater healing, as measured by the reduction in the size of the scratch, is extemely efficient and completely healed any surface scratches. This is compared with room temperature healing in moist environments where healing efficiency is more than 60% after 6 h. In a hot dry environment, no healing is observed The healing mechanism is investigated using 3D profilometry, optical microscopy and fourier transform IR spectroscopy (FTIR) which revealed that scratches become wider at the scratch rim, but more shallow over time. It is propsed that the presence of moisture at the base of the scratch facilitates a zipping up effect as the surface comes together to re-esterify.

A novel UV/thermal dual-curing thiol-ene/polyurethane acrylate (PUA) coating of PUA oligomer, tripropylene glycol diacrylate, 2,4,6-trimethylbenzoyldiphenyl phosphine oxide, and trimethylolpropane tris (3-mercaptopropionate) was prepared The coating had a rapid surface drying rate with UV radiation (400 W, 50 W/cm2). For example, the surface of the novel thiol-ene/PUA coating dried within 3 s. The hardness, gel content, and initial decomposition temperature at 5 wt% weight loss of the UV/thermal dual-cured sample after 10 min of UV irradiation, followed by heating at 150°C for 20 min, were 37 D, 90.3%, and 302.2°C, resp., which were higher than the 30 D, 87.7% and 284.9°C of the UV curing control after 10 min of UV irradiation The curing time of the 1-mm-thick coating was 4.5 min in indoor sunlight (2.3 ± 0.3 mW/cm2) with a gel content of 83.8%. This coating could be applied in the rapid prototyping field with UV or sunlight exposure. Thermal treatment after UV curing could increase the crosslinking degree and influence the sample performance.

Kamatani, Yoshio published the artcileReaction of an oxadiazinetrione derivative and its application to polyurethane coatings, SDS of cas: 2212-32-0, the main research area is isocyanate oxadiazinetrione derivative crosslinker; amine catalyst urethane formation; phosphine catalyst urethane formation; lead octanoate catalyst; polyurethane coating crosslinking agent.

In the reaction of 3,5-bis(6-isocyanatohexyl)-2H-1,3,5-oxadiazine-2,4,6(3H,5H)-trione (I) [50639-37-7] with H(OCH2CH2)2OMe [111-77-3] in solution at 70°, tertiary amines, Bu3P, and Pb octanate were good catalysts, giving conversions of 87-100%. In the reaction of I with Bu methacrylate-hydroxyethyl methacrylate-iso-Bu methacrylate-styrene copolymer  [77402-19-8] to give a coating, tertiary amines were suitable catalysts. In curing polyurethane coatings at relative humidity (RH) 0% and 50%, I is a little more reactive than tris(6-isocyanatohexyl)biuret (II), and the dependence of I reactivity on RH is smaller than that of II. Coatings from I-based polyurethanes had good curability in early stages, while those from II- and tris(6-isocyanatohexyl)isocyanurate-based polyurethanes required 2-3 times longer to attain the same hardness.

Stalin, Sanjuna published the artcileDesigning Polymeric Interphases for Stable Lithium Metal Deposition, Name: Pentaerythritol tetra(3-mercaptopropionate), the main research area is lithium battery solid electrolyte interphase fluorinated polymer coating stability; Electrochemistry; Lithium batteries; Operando-Microscopy; Polymer Coatings; Solid electrolyte interphases; Stability Analysis.

Reactive metals are known to electrodeposit with irregular morphol. features on planar substrates. A growing body of work suggest that multiple variables: composition, mechanics, structure, ion transport properties, reductive stability, and interfacial energy of interphases, formed either spontaneously or by design on the metal electrode play important but differentiated roles in regulating these morphologies. We examine the effect of fluorinated thermoset polymer coatings on Li deposition by means of experiment and theor. linear stability anal. By tuning the chem. of the polymer backbone and side chains, we investigate how phys. and mech. properties of polymeric interphases influence Li electrodeposit morphol. It is found that an interplay between elasticity and diffusivity leads to an optimum interphase thickness and that higher interfacial energy augments elastic stresses at a metal electrode to prevent out-of-plane deposition. These findings are explained using linear stability anal. of electrodeposition and provide guidelines for designing polymer interphases to stabilize metal anodes in rechargeable batteries.
