A deep learning-based quantitative prediction model for the processing potentials of soybeans as soymilk raw materials.

Current technologies as correlation analysis, regression analysis and classification model, exhibited various limitations in the evaluation of soybean possessing potentials, including single, vague evaluation and failure of quantitative prediction, and thereby hindering more efficient and profitable soymilk industry. To solve this problem, 54 soybean cultivars and their corresponding soymilks were subjected to chemical, textural, and sensory analyses to obtain the soybean physicochemical nature (PN) and the soymilk profit and quality attribute (PQA) datasets. A deep-learning based model was established to quantitatively predict PQA data using PN data.

Binary blends of normal corn starch and cow cockle starch for the slow-thickening behavior upon pasting.

Corn starch with slow thickening property may facilitate more efficient heat transfer and safety of corn starch-thickened foods. Partial substitution of normal corn starch (NCS) with slow-pasting behavior of cow cockle starch (CCS) was hypothesized to impart binary starch blend with slow-thickening effect during hydrothermal heating. To test hypothesis, a series of starch blend dispersions (with weight ratios of CCS to NCS = 75:25, 50:50, 25:75) were prepared at various starch concentrations (6 %, 8 %, 10 %, and 12 %) and subjected to the Rapid Viscosity Analysis (RVA).

Molecular rotor as an in-situ fluorescent probe for the degree of polymerization of α-D-1,4-glucans.

Various starch synthesis and tailoring processes involve prevailing adjustments in the degree of polymerization (DP) of linear α-D-1,4-glucan chains (LGCs) for the improved functional performances. Previous studies indicated that LGCs might hinder the twisted relaxation of 9-(2-carboxy-2-cyanovinyl)-julolidine (CCVJ, a hydrophilic molecular rotor), highlighting CCVJ as a potential in-situ structural probe for LGC. In this study, glucose and its α-D-1,4 oligomers and polymers with molecular weights ranging from 0.

Super-resolution microscopy enabled by high-efficiency surface-migration emission depletion.

Nonlinear depletion of fluorescence states by stimulated emission constitutes the basis of stimulated emission depletion (STED) microscopy. Despite significant efforts over the past decade, achieving super-resolution at low saturation intensities by STED remains a major technical challenge. By harnessing the surface quenching effect in NaGdF:Yb/Tm nanocrystals, we report here high-efficiency emission depletion through surface migration.

Molecular rotor as a structural probe of glucan polymers: Amylopectin, phytoglycogen, and their β-limit dextrins as models.

Fluorescence emissions of molecular rotors (MRs) are affected by local restrictions to molecular motion, and therefore it was considered that MRs can be used as structural probes of biopolymers. In this study, 9-(2-carboxy-2-cyanovinyl)-julolidine (CCVJ), a hydrophilic MR, was used to differentiate branched α-D-glucans, including amylopectin, phytoglycogen, and their β-limit dextrins. CCVJ emissions of glucan dispersions were correlated with dispersion viscosities and glucan branch structures.

Anisotropic Excitation Polarization Response from a Single White Light-Emitting β-NaYF :Yb ,Pr Microcrystal.

Precise knowledge about optical and structural performance of individual rare earth (RE)-doped particles is extremely important for the optimization of luminescent particles and for fully exploiting their capability as multifunctional probes for interdisciplinary applications. In this work, optical and structural anisotropy of individual particles through RE-doped single fluoride microcrystals with controllable morphology is reported. Unique luminescent phenomena, for example, white light-emission from Pr at single particle level and different photoluminescent spectra variation dependence on excitation polarization orientation at different excitation direction are observed upon excitation with a 980 nm linearly polarized laser.

On the decay time of upconversion luminescence.

In this study, we systematically investigate the decay characteristics of upconversion luminescence (UCL) under anti-Stokes excitation through numerical simulations based on rate-equation models. We find that a UCL decay profile generally involves contributions from the sensitizer's excited-state lifetime, energy transfer and cross-relaxation processes. It should thus be regarded as the overall temporal response of the whole upconversion system to the excitation function rather than the intrinsic lifetime of the luminescence emitting state.

Fast upconversion super-resolution microscopy with 10 μs per pixel dwell times.

Multi-photon upconversion super-resolution microscopy is a recently proposed imaging modality, based on lanthanide-doped nanocrystals, which can emit visible emission upon low-intensity near-infrared excitation. This imaging modality exhibits many advantages, including increased imaging depth, high signal-to-noise ratio, low phototoxicity, and high photostability. However, two factors seriously restrict its scanning speed, sometimes even to an intolerable degree; the long lanthanide emission lifetime and the low brightness.

One-scan fluorescence emission difference nanoscopy developed with excitation orthogonalized upconversion nanoparticles.

We experimentally realized one-scan fluorescence emission difference nanoscopy (FED) by simultaneously imaging two different color emissions of NaYF:Er@NaYF@NaYF:Yb/Tm upconversion nanoparticles. Under the irradiation of two synchronized laser beams, a solid 940 nm beam and a hollow 808 nm beam, green emission of Er and blue emission of Tm can be orthogonally generated and collected. After simple subtraction, a resulting super-resolution image featuring 54 nm resolution was obtained.

Non-bleaching fluorescence emission difference microscopy using single 808-nm laser excited red upconversion emission.

Optical super-resolution microscopy has become a powerful technique to help scientists to monitor the sample of interest at nanoscale. Fluorescence emission difference (FED) microscopy, a very facile super-resolution method, does not require high depleting laser intensity and is independent on the species of agents, which makes FED microscopy possess great potential. However, to date, the biomarkers applied in FED microscopy usually suffer from a photo-bleaching problem.

Ruthenium complex-modified carbon nanodots for lysosome-targeted one- and two-photon imaging and photodynamic therapy.

Nanohybrids can in most cases kill cancer cells more efficiently as compared with free photosensitizers. In this work, we constructed nanohybrid Ru1@CDs composed of carbon nanodots (CDs) and a phosphorescent Ru(ii) complex (Ru1) for one- and two-photon photodynamic therapy of cancer. The photosensitizer and imaging agent Ru1 is decorated onto the nanocarrier CDs covalently.

Achieving high-efficiency emission depletion nanoscopy by employing cross relaxation in upconversion nanoparticles.

Stimulated emission depletion microscopy provides a powerful sub-diffraction imaging modality for life science studies. Conventionally, stimulated emission depletion requires a relatively high light intensity to obtain an adequate depletion efficiency through only light-matter interaction. Here we show efficient emission depletion for a class of lanthanide-doped upconversion nanoparticles with the assistance of interionic cross relaxation, which significantly lowers the laser intensity requirements of optical depletion.
