Removing mesopores from metal-organic framework MIL-100(Cr) membranes for superior CO2 separation

Membranes with high CO2 permeance and satisfactory CO2/N2 selectivity have been in demand for industrial applications, especially for the first stage of two-stage membrane-based process. MOF membranes with abundant pores have the potential to achieve high CO2 permeance, but most current MOF membranes fall short of the requirements (CO2 permeance >3000 GPU). Research on novel MOF membranes is urgently needed. Here, a new kind of non-crystalline (NC) MIL-100(Cr) membrane removed mesopores is fabricated by a non-fine assembly process. NC-MIL-100(Cr) possesses similar bonding structure and surface properties to crystalline MIL-100(Cr), but delivers more suitable pore size and high processibility for membrane formation. NC-MIL-100(Cr) membranes are prepared under different Cr3+ concentrations in reaction solution and secondary growth durations, among which NC-MIL-100(Cr) membranes prepared with Cr3+ concentration of 2 mmol/mol DMF and secondary growth duration of 36 h display CO2 permeance of about 4638 GPU and CO2/N2 selectivity of about 35 for mixed CO2/N2 (15/85, v/v) separation, as well as CO2 permeance of about 8670 GPU for single CO2 permeation.

The LAM crystal grown at pH 6.4 show high values of third order nonlinear optical parameters, as compare to other grown crystals, that attest its suitability for applications like higher harmonic generation, optical switching, optical limiting and other photonic applications over other grown crystals. Thermal stability of the grown crystals has been attested by TG-DTA study.

On a class of a coupled nonlinear viscoelastic Kirchhoff equations variable-exponents: global existence, blow up, growth and decay of solutions

In Situ Monitoring and Tuning Multilayer Stacking of Polymer Lamellar Crystals in Solution with Aggregation-Induced Emission.

Many types of self-assembled 2D materials with fascinating morphologies and novel properties have been prepared and used in solution. However, it is still a challenge to monitor their in situ growth in solution and to control the number of layers in these materials. Here, we demonstrate that the aggregation-induced emission (AIE) effect can be applied for the in situ decoupled tracing of the lateral growth and multilayer stacking of polymer lamellar crystals in solution. Multilayer stacking considerably enhances the photoluminescence intensity of the AIE molecules sandwiched between two layers of lamellar crystals, which is 2.4 times that on the surface of monolayer crystals. Both variation of the self-seeding temperature of crystal seeds and addition of a trace amount of long polymer chains during growth can control multilayer lamellar stacking, which are applied to produce tunable fluorescent patterns for functional applications.

Real-time monitoring of CdTe quantum dots growth in aqueous solution

Quantum dots (QDs) are remarkable semiconductor nanoparticles, whose optical properties are strongly size-dependent. Therefore, the real-time monitoring of crystal growth pathway during synthesis gives an excellent opportunity to a smart design of the QDs luminescence. In this work, we present a new approach for monitoring the formation of QDs in aqueous solution up to 90 °C, through in situ luminescence analysis, using CdTe as a model system. This technique allows a detailed examination of the evolution of their light emission. In contrast to in situ absorbance analysis, the in situ luminescence measurements in reflection geometry are particularly advantageous once they are not hindered by the concentration increase of the colloidal suspension. The synthesized particles were additionally characterized using X-ray diffraction analysis, transition electron microscopy, UV-Vis absorption and infrared spectroscopy. The infrared spectra showed that 3-mercaptopropionic acid (MPA)-based thiols are covalently bound on the surface of QDs and microscopy revealed the formation of CdS. Setting a total of 3 h of reaction time, for instance, the QDs synthesized at 70, 80 and 90 °C exhibit emission maxima centered at 550, 600 and 655 nm. The in situ monitoring approach opens doors for a more precise achievement of the desired emission wavelength of QDs.

By studying the conversion ratio of TSD to basal plane defects during physical vapour transport (PVT) growth and hybrid growth (combination of solution growth and PVT growth) on various off-angle seeds, we suggest an energy diagram showing the off-angle dependence of the dislocation energy which explains the activation barrier of dislocation conversion.

Effect of Annealing Temperature on the Structural Properties of Dual Solution Synthesized AlS: ZnS Thin Films

Using two solution-based techniques—solution growth technique (SGT) and sequential ionic layer adsorption and reaction (SILAR) AlS: ZnS alloyed thin films were successfully produced on glass substrates. The sources of Al, Zn, and S were aluminum sulphate (AlSO4.7H20), zinc sulphaate (ZnSO4.7H20), and sodium thiosulphate (Na2S2S03). The complexing agent that was utilized was ethylene diamine tetraacetic acid (EDTA). Using a Master Chef Annealing Machine, the deposited alloyed samples were annealed between 373K and 523K. The scanning electron microscope (SEM) and X-ray diffractometer (XRD) were used for the crystallographic investigations. Samples R1 and R6 AlS: ZnS alloyed thin films exhibit well-defined peaks in their XRD pattern, indicating that they are polycrystalline in nature. We computed their grain sizes. Spectroscopy using Rutherford backscattering (RBS). Analysis using Rutherford backscattering spectroscopy (RBS) verified the composition of aluminum, zinc, and sulfur in the alloyed thin films. The microstructure of the deposited alloyed thin films is revealed by the results of surface electron microscopy. Two significant semiconductor materials that have potential uses in optoelectronics, photovoltaics, and sensing devices are aluminum sulfide (AlS) and zinc sulfide (ZnS). Depositing these materials in thin films at a reasonable cost and with good efficiency is possible with dual solution synthesis. However, the annealing temperature, a crucial factor in establishing the crystal structure, morphology, and optical properties of these films, can have an impact on their structural characteristics. Prior studies have examined how the annealing temperature affects the structural characteristics of AlS and ZnS thin films separately; however, the dual solution-produced AlS: ZnS thin films have not received as much attention. The purpose of this work is to examine how the annealing temperature affects the crystal structure and surface morphology of AlS: ZnS thin films. The results of this investigation can offer significant understanding regarding the refinement of the annealing temperature to produce superior AlS: ZnS thin films for a range of uses. Based on their properties, sulphide alloyed thin films could find applications in microelectronics, window coating, and antireflection coating. They work well as coatings for eyeglasses and as absorber layers for photocells, among other applications.

Novel application of high temperature solution growth method in simultaneously preparing SiC/Ti3SiC2/TiC using photovoltaic Si waste and Ti-bearing blast furnace slag

Photovoltaic silicon wastes (PVSWs) and Ti-bearing blast furnace slag (TBBFS) are typical new energy solid waste and traditional industrial solid waste respectively. The collaborative treatment of PVSW and TBBFS can realize the utilization of Si and Ti resources, as well as safeguard the ecosystems. Herein, an effective approach was proposed to prepare SiC, Ti3SiC2, and TiC using these two wastes as raw materials based on the innovative application of High Temperature Solution Growth Method (HTSGM). A Ti–Si alloy, which is rich in TiSi2 phase (stable) with a low melting point is synthesized from TBBFS through silicothermal reduction at a low operating temperature of HTSGM. Subsequently, the directional solidification process effectively optimized the segregation and carbon solubility of Ti–Si alloy, leading to the formation of TiC, Ti3SiC2, and SiC. The effect of directional solidification rate and the electromagnetic field is analyzed on in situ carburizing behavior and segregation of Ti–Si alloy, as well as controlled precipitation interval of the three carbides. Through the microcrystalline materialization treatment strategy of the associated waste slag, the entire process is devoid of solid waste or other pollution, achieving high-value and complete utilization of the two solid wastes. This work provides an innovative process for the green, clean, efficient, and high-quality collaborative treatment of PVSW and TBBFS.

Transcriptional Analysis of Mixed-Culture Fermentation of Lachancea thermotolerans and Saccharomyces cerevisiae for Natural Fruity Sour Beer

Increasingly high interest in yeast–yeast interactions in mixed-culture fermentation is seen along with beer consumers’ demands driving both market growth and requests for biotechnological solutions that can provide better sensory characteristics. In this study, Lachancea thermotolerans and Saccharomyces cerevisiae with a cell population ratio of 10:1 were inoculated for sour beer fermentation while the process conditions within the brewing industry remained unchanged. With L. thermotolerans producing lactic acid (1.5–1.8 g/L) and bringing down the pH to 3.3–3.4 whilst adding no foreign flavors herein, this study revealed a new natural, fruity sour beer with a soft, sour taste. In this study, the double-yeast mixed-culture fermentation produced more flavor substances than a single-culture process, and plenty of isobutyl acetate and isoamyl acetate enhanced the fruit aroma and balanced the sour beer with a refreshing taste. While playing a positive role in improving the beer’s quality, the double-yeast mixed-culture fermentation developed in this study helps to offer an alternative mass production solution for producing sour beer with the processes better controlled and the fermentation time reduced. The stress responses of the L. thermotolerans during the fermentation were revealed by integrating RNA sequencing (RNA-Seq) and metabolite data. Given that the metabolic flux distribution of the S. cerevisiae during the fermentation differed from that of the non-Saccharomyces yeasts, transcriptional analysis of non-Saccharomyces yeast and S. cerevisiae could be suitable in helping to develop strategies to modulate the transcriptional responses of specific genes that are associated with the aroma compounds released by S. cerevisiae and non-Saccharomyces yeasts. In the case of some non-Saccharomyces yeast species/strains, the diversion of alcoholic fermentation and the formation of a great number of secondary compounds may, in part, account for the low ethanol yield.
