摘要：
In this paper, starch was first liquefied using sulfamic acid as catalyst, and then the starch-based polyurethane coating was prepared. The optimum ratio between the hydroxyl group of liquefied starch and isocyanate group of PM200 was determined to be 1:1.3. Differential scanning calorimetry was used to study the curing reaction kinetics of starch-based polyurethane, and the result showed that the initial temperature (Ti), peak temperature (Tp) and end temperature (Tf) of thermostatic curing reaction were 23.31 degrees C, 83.15 celcius and 199.75 celcius, respectively. According to the Kissinger model, the calculated activation energy and preexponential factor of the curing reaction system were 44.34 kJ mol-1 and 7.36 x 103 s-1, respectively. Meanwhile, the Crane model indicated that the order of curing reaction was 0.88. The curing kinetic equation was also established to provide a theoretical basis for the actual curing process of starch-based polyurethane materials.

摘要：
The synthesis of aldehyde compounds under mild conditions enabled by visible light-induced organic reactions is highly attractive in modern chemistry. Reagents including glyoxylic acid (or its derivatives), vinylene carbonate, methylamines, 1,3-dioxolane, and & alpha;-chloro N-methoxyphthalimide (PhthOCH(2)Cl), are found to be sources of the aldehyde group in photocatalytic reactions. This review summarizes the recently developed photocatalytic strategies for the installation of the formyl group into various scaffolds, mainly through the key steps of photocatalytic decarboxylation, oxidation coupling with methylamines/hydrolysis, hydrogen atom transfer of 1,3-dioxolane, and direct generation of formyl radicals.

摘要：
The resonance light scattering method was used to study the coordination-driven self-assembly reaction of zinc with a bipolar tetradentate ligand and a bipolar bidentate ligand to form a supramolecular polymer. The bipolar tetradentate ligand was N,N'-bis(pyridoxal phosphate)-o-tetraminobiphenyl synthesized by the reaction of pyridoxal phosphate with biphenyltetramine, and the bipolar bidentate ligand was bis-phenanthroline-glutaraldehyde synthesized by the reaction of glutaraldehyde with 5-aminophe-nanthroline. The formation of the supramolecular polymer causes signal enhancement of resonance light scattering. Based on this, we established a new method for the determination of zinc by resonance light scattering. Under optimized experimental conditions, the zinc concentration in the range of 0.3-30 ng/mL showed a good linear relationship with the resonance light scattering intensity of the system. The detection limit of the method is 0.1 ng/mL. Using this method to determine the content of zinc in food, the recovery rate of standard addition is between 95 and 107%, and the relative standard deviation is less than 3.68%.

摘要：
Two new Mo‐complexes with N, S‐bidentate ligands were synthesized, and show good catalytic activity in the reduction of nitrate to nitrite. The addition of Lewis acid Sc(III) significantly accelerated the cycle rate of the Mo‐catalyst. Abstract Two readily‐accessible molybdenum complexes with low sterically hindered S, N‐bidentate ligands were designed for the reduction of nitrate to nitrite. The Lewis acid Sc(III) acted as a significant co‐catalyst to enhance the catalytic efficiency by activating the N−O bond of nitrate. This study indicates that molybdenum complexes in cooperation with a Lewis acid offer functional Mo‐catalyst systems, which present functional artificial models of the natural molybdenum enzymes.

摘要：
Rationally tuning the emission position and narrowing the full width at half-maximum (FWHM) of an emitter is of great importance for many applications. By synergistically improving rigidity, strengthening the resonant strength, inhibiting molecular bending and rocking, and destabilizing the HOMO energy level, a deep-blue emitter (CZ2CO) with a peak wavelength of 440 nm and an ultranarrow spectral FWHM of 16 nm (0.10 eV) was developed via intramolecular cyclization in a carbonyl/N resonant core (QAO). The dominant upsilon(0-0) transition character of CZ2CO gives a Commission Internationale de I'eclairage coordinates (CIE) of (0.144, 0.042), nicely complying with the BT.2020 standard. Moreover, a hyper-fluorescent device based on CZ2CO shows a high maximum external quantum efficiency (EQE(max)) of 25.6 % and maintains an EQE of 22.4 % at a practical brightness of 1000 cd m(-2).

摘要：
Sensors are regarded as a fundamental vector for sustainable development of future advanced civilization. To satisfy the demands of future generations, fabrication of advanced sensor systems integrated with artificial intelligence (AI), fifth generation (5G) connectivity, machine learning (ML), and internet of things (IoTs) is growing very fast. Incorporation of two-dimensional (2D) nanomaterials (NMs) with IoTs/5G/AI/ML technologies has transformed wide range of sensor applications in healthcare, wearable electronics for, safety, environment, military, space, and agriculture sectors. Finally, to operate those sensors we need powerful energy storage devices (ESDs) and hence advance 2D NMs. Since the discovery of MXenes NMs in 2011, and 2D boron nanosheets (NSs) (borophene) on Ag substrates (2015) their research has been accelerated in the domains of advanced nanotechnological world. Borophene and MXenes NMs have came out as an outstanding 2D NMs to construct next generation novel sensors and ESDs due to their novel physicochemical properties and surface functions. By lowering costs, requiring fewer resources (including labor), and minimizing contamination, ML/AI based theoretical simulation has effectively directed the study and manufacturing of improved 2D NMs based sensors/ESDs applications on large scale industrial level. Modern 2D NMs based flexible sensors and ESDs can fundamentally alter the traditional sensing/ESDs technologies since they are adaptable, wearable, intelligent, portable, biocompatible, energy-efficient, self-sustaining, point-of-care, affordable etc. this review summarized the MXenes and borophene NMs synthesis with corresponding achievements, and there advancement, limitations, and challenges in sensors/ESDs technological applications.
摘要：
The conversion of superoxide radical (& BULL;O2 ) to hydrogen peroxide (H2O2) is critical in the photocatalytic for-mation of H2O2 via the sequential two-step single-electron oxygen reduction mechanism. Providing a high concentration of & BULL;O2  is an effective approach to promoting this process in terms of chemical kinetics. It is, however, extremely challenging to implement this idea in the photocatalytic solution due to the limited lifespan of & BULL;O2 . To this end, a concept about local & BULL;O2  enrichment catalyst surface was proposed in this study and achieved in an innovative PSI/C3N4 photocatalyst. The results of theoretical calculations and temperature-dependent photocatalytic studies indicate that PSI on the C3N4 surface can serve as a diffusion buffer for & BULL;O2 , capturing them through Van der Waals interactions and separating them by energy perturbations. As a result, a local enrichment of & BULL;O2  was established on the PSI/C3N4 surface during photocatalysis, strengthening the photocatalytic conversion of & BULL;O2  to H2O2, thus allowing the PSI/C3N4-4 photocatalyst to produce H2O2 at a rate of approximately 2.4 and 2.65 times greater than pure C3N4 under visible light and LED irradiation, respectively. This study presents a promising strategy for enhancing photocatalytic H2O2 production efficiency by selectively enriching & BULL;O2  on the catalyst surface.

摘要：
A convenient and portable smartphone-assisted method for the colorimetric detection of uranyl ions (UO22+) in aqueous solutions is proposed using rifampicin and 2-(5-bromo-2-pyridylazo)-5-diethylaminophenol (Br-PADAP) as chromogenic agents. The addition of UO22+ would cause reaction with chromogenic agents to form complexes, changing the colour from orange to dark red in the rifampicin system and from yellow to light pink in the Br-PADAP system. To achieve the on-site estimation of the trace UO22+ concentration range, digital images of colour changes captured by the smartphone under fixed lighting conditions were imported into the built-in application named "Detect" to obtain HSV (hue, saturation, and value) and HSL (hue, saturation, lightness) information, which could be associated with the concentration of uranyl ions. For more precise laboratory-level detection, ultraviolet-visible (UV-vis) spectroscopy was employed as well. The absorbance of the rifampicin system exhibited strong linearity with the UO22+ concentration in the range from 4 to 50 mu M at 375 nm with a method detection limit (MDL) of 3.17 mu M by the UV-vis-based method, while that of Br-PADAP system had a linear relationship with the concentration from 0.9 to 7 mu M at 562 nm with an MDL of 0.89 mu M. The two strategies may be combined to detect UO22+ across a larger concentration range, and this method has been successfully used to analyze real samples including soil around uranium mines.

摘要：
Transcription factors (TFs), transcription co-factors (TcoFs) and their target genes perform essential functions in diseases and biological processes. KnockTF 2.0 (http:////www.licpathway.net//KnockTF//index.html) aims to provide comprehensive gene expression profile datasets before//after T(co)F knockdown//knockout across multiple tissue//cell types of different species. Compared with KnockTF 1.0, KnockTF 2.0 has the following improvements: (i) Newly added T(co)F knockdown//knockout datasets in mice, Arabidopsis thaliana and Zea mays and also an expanded scale of datasets in humans. Currently, KnockTF 2.0 stores 1468 manually curated RNA-seq and microarray datasets associated with 612 TFs and 172 TcoFs disrupted by different knockdown//knockout techniques, which are 2.5 times larger than those of KnockTF 1.0. (ii) Newly added (epi)genetic annotations for T(co)F target genes in humans and mice, such as super-enhancers, common SNPs, methylation sites and chromatin interactions. (iii) Newly embedded and updated search and analysis tools, including T(co)F Enrichment (GSEA), Pathway Downstream Analysis and Search by Target Gene (BLAST). KnockTF 2.0 is a comprehensive update of KnockTF 1.0, which provides more T(co)F knockdown//knockout datasets and (epi)genetic annotations across multiple species than KnockTF 1.0. KnockTF 2.0 facilitates not only the identification of functional T(co)Fs and target genes but also the investigation of their roles in the physiological and pathological processes.

摘要：
As the heaviest chalcogen atom, tellurium (Te) is endowed with a high Seebeck coefficient and low lattice thermal conductivity, which are the key factors that contribute to a high ZT value in thermoelectricity. The most studied thermoelectric element is Te, and it was theoretically and experimentally studied to be an ideal thermoelectric element. However, the instability and mechanical endurance of Te thermoelectric modules cannot be guaranteed, especially in flexible electronic devices. A focused Te/polymer strategy was recently developed and implemented to address these problems, so combining nanostructured Te with flexible polymers can be an efficient way to construct stable, efficient and flexible thermoelectric generators. In this review, the use of nanostructured Te for thermoelectricity is summarized in brief, and then the preparation methods of Te/polymers are reviewed. Subsequently, the thermoelectric properties and applications of Te/polymers are highlighted, followed by detailed polymer types, including PEDOT:PSS, PANI, P3HT and PPy. Finally, based on current progress and achieved results, the prospects and future directions of Te/polymers are highlighted and discussed.

摘要：
A novel chitosan-based porous composite adsorbent with multifunctional groups, such as phosphoric acid, amidoxime, and quaternary ammonium groups, was prepared to improve the adsorption rate and competitive uranium‑vanadium adsorption of amidoxime group adsorbents. The maximum uranium adsorption capacity of PACNC was 962.226mgg(-1) at 308K and pH=7. The maximum adsorption rate constant of PACNC for uranium was 2.83E-2gmg(-1)min(-1), which is 2.38 times that of ACNC (1.19E-2gmg(-1)min(-1)). Moreover, the adsorption equilibrium time was shortened from 300 (ACNC) to 50 (PACNC) min. In simulated and real seawater, the K(d) and adsorption capacity of PACNC for uranium were approximately 8 and 6.62 times those for vanadium, respectively. These results suggest that phosphorylation significantly improved the competitive adsorption of uranium‑vanadium and uranium adsorption rate. PACNC also exhibited good recycling performance and maintained stable adsorption capacity after five cycles. DFT calculations were used to analyze and calculate the possible co-complex structure of PACNC and uranium. The binding structure of phosphate and amidoxime is the most stable, and its synergistic effect effectively improves the competitive adsorption of uranium-vanadium of amidoxime. All the results demonstrated that PACNC has substantial application potential for uranium extraction from seawater.

摘要：
A concise and efficient ring-opening difluorination strategy was developed for the synthesis of highly functionalized hydroxy-containing alpha,alpha-difluoro-beta-ketoamides from the one-pot multicomponent reaction of 4-aminocoumarins, NFSI, and water in dimethyl carbonate (DMC) as a green solvent. The reactions were smoothly achieved under visible light irradiation in air at room temperature without the addition of any other external photocatalysts. With this protocol, various alpha,alpha-difluoro-beta-ketoamides were successfully synthesized under mild conditions (25 examples, 73-91% yields). This transition-metal-free synthetic procedure shows good functional group compatibility and attractive practical potential for large-scale synthesis.

摘要：
An efficient synthesis of densely 1,2,4-triazoles has been achieved by [3+2] cycloaddition of nitrileimides with amidine hydrochlorides under transition metal-free conditions. This method features mild reaction conditions, wide substrate scope and good functional group tolerance. A series of aryl, heterocyclic and alkyl substituted 3-CF3-1,2,4-triazoles were synthesized smoothly under the promotion of NaHCO3 and yield up to 96%. In addition, both gram-scale reaction and synthetic transformations are smoothly elaborated to indicate the utility of this reaction.
