This study investigated the in vitro fermentation profiles of human milk oligosaccharides(HMOs) by different dominating infant microbiota(***-, ***-and Bacteroides-dominated inocula). We sought to evaluate fecal microbiota composition of healthy infant donors in Guangzhou(including breast-feeding and formula-feeding). Further, we were expected to study in vitro fermentation outcomes of six commercial HMOs [i.e., 2 -fucosyllactose(2 -FL), 3-fucosyllactose(3-FL), 3 -sialyllactose(3 -SL), 6 -sialyllactose(6 -SL), lacto-Ntetraose(LNT) and lacto-N-neotetraose(LNnT)], fructo-oligosaccharide(FOS) and galacto-oligosaccharides(GOS) by using individual infant fecal inocula. Methods Nineteen healthy donors were selected at Guangzhou, China. Nine infants were qualified and enrolled in the experiment. Each 50 mg of carbohydrate sample was equivalently weighted into anaerobic tubes and fermented with fecal slurry at 37 °C water bath with gentle shaking for various time periods. Total gas production of each tube was measured by inserting the needle through rubber stopper with a graduated syringe. The concentration of short chain fatty acids(SCFAs) was determined by gas chromatography, and the concentration of organic acids(OAs) was determined by high performance liquid chromatography. DNA extraction from the fermented products was performed using the OMEGA Soil DNA Kit(M5635-02)(Omega Bio-Tek, Norcross, GA, USA), following the manufacturer s instruction. The nearly full-length bacterial 16 S rRNA from each purified DNA sample was performed to investigate microbiota composition. Results Fecal microbiota composition and microbiota classification It was noteworthy that three distinct clusters of infant gut microbiota were shown among nineteen infants. Three distinct groups were characterized by the bacteria abundance, denoted as B. longum-, B. breve-and Bacteroides-dominated inocula. Gas production In the early stage of fermentation(0-4 h), gas production of B. breve-dominat

Jumping droplets

Droplet 2024年第2期3卷 3-33页

作者： jonathan B.Boreyko Department of Mechanical Engineering Virginia TechBlacksburgVirginiaUSA

When microdroplets with quasi-spherical contact angles coalesce together on a low-adhesion substrate,the capillary-inertial expansion of the liquid bridge induces a dramatic out-of-plane jumping event due to symmetry *** the onset of merging,droplet jumping initiates after a capillary-inertial time scale of tci∼1–100μs with characteristic jumping speeds of order vj∼0.1m/*** coalescenceinduced jumping-droplet effect is most commonly observed among a population of growing dew droplets on a superhydrophobic condenser,but can also occur by colliding deposited droplets together or during droplet sliding on fog *** this review,we cover the historical development of capillary-inertial jumping droplets,summarize the decade-long effort to rationalize the ultra-low energy conversion efficiency and critical droplet size of the phenomenon,and then present 15 variations on a theme of ***-inertial jumping droplets are not only a visceral illustration of the surprising power of surface tension at the microscale but they also have the potential to enhance phase-change heat transfer,enable selfcleaning surfaces,combat frost formation,harvest energy,and govern the rate of disease spread for wheat crops.

The halide migration effect in mixed-halide lead-based perovskite is a serious problem hindering the development of its display *** this study,we have successfully addressed this issue by reporting formadinium(FA)doped mixed-halide perovskite nanocrystals(NCs)with ultra-deep-blue emission of 450 nm,narrow bandwidth of 16 nm,and a high photoluminescence quantum yield(PLQY)of 66%.The perovskite nanocrystal light-emitting diodes(NC-LEDs)using this nanocrystal as an active layer achieved a maximum external quantum efficiency(EQE)of 0.32%,30-fold improved compared to that of pristine and stable electroluminescence(EL)spectra at 450 nm under a 4.9–8.0 V *** findings demonstrate the potential of our approach in developing stable and efficient deep blue perovskite NC-LEDs.
