Ultraviolet (UV) light is known to be harmful human health and cause organic materials undergo photodegradation. In this Research Article, bioinspired dopamine–melanin solid nanoparticles (Dpa-s NPs) hollow (Dpa-h as UV-absorbers were introduced enhance the UV-shielding performance of polymer. First, Dpa-s NPs synthesized through autoxidation dopamine in alkaline aqueous solution. Dpa-h prepared by spontaneous oxidative polymerization solution onto polystyrene (PS) nanospheres template,...
Spatial transcriptomics (ST) technologies have revolutionized our understanding of cellular ecosystems. However, these face challenges such as sparse gene signals and limited detection capacities, which hinder their ability to fully capture comprehensive spatial expression profiles. To address limitations, we propose leveraging single-cell RNA sequencing (scRNA-seq), provides data but lacks context, enrich ST Herein, introduce SpaIM, an innovative style transfer learning model that utilizes...
The methylimidazolium chloride ionic liquid (IL) was successfully used for the dissolution of cotton cellulose. IL and IL-cellulose were investigated by X-ray diffraction (XRD) Fourier transform infrared (FT-IR) spectroscopy analyses. obtained applied to wool hair keratin fiber surfaces, forming a fine coating layer. From FT-IR XRD analyses, results suggested reduction hydrogen bonds crystallinity in IL-cellulose-coated fibers. This effect caused covering with coating, good intrinsic...
This study develops a stylized theoretical model to analyze how digital economy agglomeration affects energy efficiency. Then, we employ two-way fixed effect identify the impact of on We find that higher degree significantly increases city's result is robust when address endogeneity concerns by exploiting policy shock, geographic distance, and historical variation as instruments. explore several explanations, including advancements in green technology, upgrading industrial structures,...
Reversible cross-linking of alkoxyamine-containing hydrophilic dynamic covalent polymers in aqueous media has been accomplished. Water-soluble with alkoxyamine units the side chains were synthesized by radical copolymerization 2-(dimethylamino)ethyl methacrylate and methacrylic esters units, subsequent protonation dimethylaminoethyl groups hydrochloric acid. By heating water at 100 °C a closed system, hydrogels formed exchange reactions. Because reactions are tolerant water, chain caused...
In this work a process for the bio-coloration of bacterial cellulose (BC) membranes was developed. Laccase from Myceliophthora thermophila immobilized onto BC and retained up to 88% residual activity after immobilization. Four compounds belonging flavonoids family were chosen test in situ polymerase laccase. All successfully polymerized by laccase giving rise yellow, orange dark brown oligomers which conferred color support. The optimal conditions studied two tested flavonoids, catechol...
Abstract Bacterial cellulose (BC) was obtained by static cultivation using commercial BC gel from scoby. membranes (oven dried and freeze‐dried) were swelled with 8% NaOH, in the absence presence of ultrasound (US), for 30, 60, 90 min. The influence swelling conditions on both physico‐chemical properties molecules entrapment evaluated. Considering highest levels entrapment, an optimum procedure established: NaOH 30 min at room temperature US. Native PEGylated laccase Myceliophthora...
The laccase polymerization of catechol was performed using different reactors namely a water bath (WB), an ultrasonic (US) and high-pressure homogenizer (HPH). total content free OH the MALDI-TOF spectra polymers obtained demonstrated that reactions are favored in presence high-energy environments. Higher conversion yields degrees (DP) were after US or HPH. Molecular dynamic simulation studies supported these findings by revealing more open enzyme active site upon environments with high...
Abstract Laccase catalyzes the oxidation and polymerization of phenolic compounds in presence oxygen. Herein, we report for first time that a previous PEGylation laccase enhances polymerase activity 3‐fold compared with reaction native enzyme, as confirmed by UV/Vis spectroscopy. The catechol increased only 1.5‐fold if poly(ethylene glycol) (PEG) was added to medium reaction. Molecular‐dynamics simulations suggest formation miscible complex polycatechol PEG, which is responsible push...
Ultrasound-assisted extraction of hemicellulose and phenolic compounds from bamboo bast fibre powder was investigated. The effect ultrasonic probe depth power input parameters on the type amount products extracted assessed. results energy radical formation correlated with calculated values for anti-nodal point (λ/4; 16.85 mm, maximum amplitude) wave in aqueous medium. Ultrasonic treatment at optimum 15 mm improve 2.6-fold efficiencies lignin powder. LC-Ms-Tof (liquid chromatography-mass...
