Quantitative relationship between surface chemistry of graphene and compatibility with rubbers established by two-dimensional solubility parameters.

Hildebrand ( ) and Hansen ( , , ) solubility parameters are important indexes to predict the compatibility of components intuitively. Currently, almost all the experiments only measured the solubility parameters of the pristine graphene. Therefore, there is a lack of quantitative relationship between the surface chemistry of graphene and solubility parameters, resulting in no theoretical guidance for the surface modification of graphene.

Above 90% of MPs/plastic particles can be adsorbed on MOF materials the hydrophobic interaction, electrical attraction, π-π stacking, and van der Waals forces.

Synergistic atom co-sharing and S-scheme heterojunction: constructing Cu/CuO/CuO with ultrathin graphene-like carbon derived from basil seeds for enhanced photo-oxidation of benzyl alcohols to aldehydes.

This study is centered on the oxidative transformation of alcohols into their respective aldehyde compounds, employing an S-scheme heterostructure featuring CuO/CuO on graphene-like carbon (GLC) derived from a basil seed hydrogel. Experimental characterization and theoretical calculations highlight that the implementation of S-scheme heterostructures achieves not only enhanced charge-separation efficiency, facilitated by the interfacial built-in electric field, Cu co-sharing at the CuO/CuO interface, and electron carrier activity of the GLC support, but also maintains a strong driving force for photocatalytic organic conversion. The resulting nanocomposites play a crucial role in transferring and reducing the recombination of photoexcited charge carriers, preserving the oxidizability of CuO holes and the reducibility of CuO electrons.

In this study, four types of nanofibers were prepared electrospinning and characterized through SEM, TEM, EDS, FTIR, TG, XPS and water contact angle analyses, and the novel polystyrene/polyethersulfone nanofibers coated with copper nanoparticles (PS/PES-CuNPs nanofibers) were developed as an ideal adsorbent for the extraction of three ochratoxins from human urine. The solid-phase extractant of sample pretreatment displayed preferable sensitivity and an extraction effect, and the analytical method based on the novel packed-fiber solid-phase extraction strategy followed by high performance liquid chromatography-fluorescence detection (PFSPE-HPLC-FLD) achieved an exceedingly low limit of detection (LOD) and limit of quantification (LOQ) of 0.108-0.

Study of ternary deep eutectic solvents to enhance the bending properties of ash wood.

Deep eutectic solvents (DESs) are considered one of the most promising biomass pretreatment reagents, and their research applications in woody fibrous biomass are increasing yearly. Inspired by the research related to wood bending, we explored the effects of different DES systems on the bending development of wood, and the results showed that the addition of anhydrous ferric trichloride to the DES system of lactic acid/choline chloride could enhance the treatment effect that increased the bendability and torsion resistance of ash wood. The anhydrous FeCl could act as an active site and provide acidic protons to improve the treatment efficiency of DES.

Effect of M-type reactive dyes on dyeing properties of twisted bamboo fiber bundles.

The dyeing properties of twisted bamboo fiber bundles were studied by using the combination of three primary colors in M-type reactive dyes. The study found that the three dyes of red, yellow and blue have good color rendering in the actual dyeing process, and because the molecular structures of the three are similar, the chemical reactions during the fixation are the same, so the final dyeing rate results are similar, which were 29-32%. Compared with the undyed twisted bamboo fiber bundle, the mechanical properties of the three-color twisted bamboo fiber bundle also changed significantly, and the tensile strength increased by 13.

DES: their effect on lignin and recycling performance.

Lignocellulosic biomass raw materials are renewable resources with abundant reserves in nature, and have many advantages, such as being green, biodegradable and cheap. Lignin, one of the three significant components of lignocellulose, possesses a chemical structure rich in phenylpropane and is a primary aromatic resource for the bio-based economy. For the extraction and degradation of lignin, the most common method is the pretreatment of lignocellulose with deep eutectic solvents (DES), which have similar physicochemical properties to ionic liquids (ILs) but address the disadvantages associated with ILs (DES have the advantages of low cost, low toxicity, and non-flammability).

The recent development of nanozymes for targeting antibacterial, anticancer and antioxidant applications.

Nowadays, nanozymes have not only been used as biosensors in the detection field, but also their application prospects in disease treatment have been explored. Numerous nanomaterials have similar catalytic activities such as peroxidase, oxidase, catalase and superoxide dismutase, and they can be used for antibacterial, anticancer and antioxidant therapy. Although there have been many studies on the application of nanozymes in the therapeutic field, the current nanozyme-based systems often lack targeting and ignore the harm to the surrounding normal tissues.

Urushiol modified epoxy acrylate as UV spray painting oriental lacquer ink.

As a natural "water-based" polymer composite material, oriental lacquer is often referred to as the "king of coatings" and is used as a coating in the defense industry, chemical industry, petroleum industry, metallurgy and mining industry, textile painting and dyeing industry, pharmaceutical industry, as well as the protection of ancient buildings and cultural relics. However, the development of modern industrialization is greatly hindered by the high viscosity of oriental lacquer, the difficulty of spraying, the long drying cycle, and the seriousness of allergenicity. Herein, based on the principle of oriental lacquer and the characteristics of prepolymer in ink, we developed a new prepolymer for modulating UV oriental lacquer ink and explored the feasibility of using it as a raw material for UV spray painting.

The InDelGT algorithm is implemented in three steps: generating an indel catalog, calling indel genotypes, and analyzing indel segregation.

Role of sulfur vacancies in MoS monolayers in stabilizing Co atoms for efficient CO oxidation.

By performing first-principles calculations, a MoS monolayer with a Co atom doped at the sulfur defect (Co-MoS) was investigated as a single-atom catalyst (SAC) for CO oxidation. The Co atom is strongly constrained at the S-vacancy site of MoS without forming clusters by showing a high diffusion energy barrier, ensuring good stability to catalyze CO oxidation. The CO and O adsorption behavior on Co-MoS surface and four reaction pathways, namely, the Eley-Rideal (ER), Langmuir-Hinshelwood (LH), trimolecular Eley-Rideal (TER) as well as the New Eley-Rideal (NER) mechanisms are studied to understand the catalytic activity of Co-MoS for CO oxidation.
