• COVID-19 pandemic is clearly challenging the entire food system. A collective action needed in order to build systems that are resilient. Food multidisciplinary and highly interconnected. security important times of shocks crises.
We report, for the first time, ballistic magnetoresistance effects in a two-dimensional electron gas (2DEG) subjected to spatially modulated periodic magnetic field. The field is formed by presence of superconducting stripes on surface heterostructure with 2DEG. observe oscillatory due commensurability effect between classical cyclotron diameter and period modulation. behavior agreement existing theory no adjustable parameters.
Abstract Hybrid meat analogues, whereby a proportion of has been partially replaced by more sustainable protein sources, have proposed to provide means for diets in the future. Consumer testing was conducted determine consumer acceptability different formulations beef burgers and pork sausages comparison with both meat‐free commercial products. Acceptability data were generated using 9‐point hedonic scale. Check‐all‐that‐apply ( CATA ) questioning used sensory attributes perceived each...
Using a multitechnique approach, two temperature domains have been identified in agarose gelation. Below 35 degrees C, fast gelation results strong, homogeneous and weakly turbid networks. The correlation length, evaluated from the wavelength dependence of turbidity, is close to values pore size reported literature. Above much slower associated with formation large-scale heterogeneities that can be monitored by marked change turbidity visualised transmission electron microscopy. Curing gels...
The deacetylation and gelation of konjac glucomannan (KGM) following alkali addition was investigated by Fourier transform infrared, while the rheological properties KGM with different molecular weights were studied dynamic viscoelastic measurements in shear mode penetration force tests. It found that occurred after significant had taken place. Rheometrical studies revealed exhibited characteristics small amplitude oscillatory flow. For samples fractionated lower weights, a decrease both...
We have observed a Fermi-edge singularity in the tunneling current between two-dimensional electron gas (2DEG) and zero-dimensional localized state. A sharp peak tunnel is when energy of state matches Fermi 2DEG. The grows becomes sharper as temperature decreased to our lowest 70 mK. attribute Coulomb interaction on site sea.
Shubnikov--de Haas and persistent-photoconductivity measurements are used to study the mobility, free-electron density (n), occupancy of DX center in heavily doped n-GaAs [Si,Sn] as a function doping level hydrostatic pressure. The results show that produces resonant donor between \ensuremath{\Gamma} L conduction-band minima at concentration comparable with level. For Si-doped samples, comparison local vibration-mode indicates can be identified ${\mathrm{Si}}_{\mathrm{Ga}}$.
We describe the design and development of a scanning tunneling micoscope (STM) working at very low temperatures in ultra-high vacuum (UHV) high magnetic fields. The STM is mounted to He3 pot an entirely UHV compatible refrigerator inside tube which can be baked out achieve conditions even room temperature. A base temperature 315 mK with hold time 30 h without any recondensing or refilling cryogenics achieved. moved from cryostat into lower UHV-chamber system where STM-tips -samples exchanged...
A molecular level description of the time course gelation polysaccharide konjac mannan (KM) is presented and role alkali addition considered in detail. NMR relaxometry utilized as a complementary methodology to mechanical spectroscopy order probe events occurring prelude network formation, high-resolution used follow deactetylation process. It shown that plays an important solubilizing facilitating deacetylation chain. Deacetylation both reducing inherent aqueous solubility polymer...
Resonant peaks are observed in the low-temperature current-voltage I(V) characteristics of a single-barrier GaAs/AlAs/GaAs diode with InAs quantum dots incorporated AlAs tunnel barrier. We argue that each peak arises from single-electron tunneling through discrete zero-dimensional state an individual dot Each splits into sharp components for magnetic field B\ensuremath{\parallel}I; curve probes density Landau-quantized states emitter-accumulation layer. A size \ensuremath{\approxeq}10 nm was...
Resonant tunneling spectroscopy is used to study the energy-level spectrum of a new chaotic dynamical system, an electron in trapezoidal potential well presence high magnetic field tilted relative confining barriers. Distinct series quasi-periodic resonances are observed current-voltage chracteristics which change dramatically with tilt angle. These related unstable closed orbits within domain. The experimental results explained by identifying and studying properties periodic accessible electrons.
Pluronics are being introduced in food research order to delay lipid digestion, with the length of hydrophilic and hydrophobic chains playing an important role rate such a process. Since bile salts play crucial digestion process, aim this work is analyze interactions between Pluronic F127 or F68 salt NaTDC when latter added at physiological concentrations. These studied Pluronic-covered oil-water interface aqueous phase Pluronic-stabilized emulsions. This has been carried out techniques as...
The disruption of starch granular structure during dissolution in varying concentrations N-methyl morpholine N-oxide (NMMO) has been studied using three maize starches with ratios amylose and amylopectin. Behavior NMMO characterized by differential scanning calorimetry (DSC), microscopy, rapid viscosity analysis (RVA), rheometry. Exothermic transitions were observed for the both 78 70% NMMO; transition changed to an endotherm at 60 50% NMMO. Consistent DSC, hot stage microscopy showed that...
