D-glucaric acid is an important bio-based building block of polymers and is a high value-added chemical that can be used in a variety of applications. In the present study, theUdhtarget genes fromPseudomonas putidaandPseudomonas syringaewere used together to construct the expression vector pETDuet-2 × Udh. The transformants of BL21 (DE3) with vector pETDuet-2 × Udh were applied to produce glucaric acid from glucuronic acid. After optimizing the induction conditions, the highest Udh expression was achieved when 0.4 mmol·L−1isopropyl-β-d–thiogalactoside (IPTG) was added to the cell cultures at an OD600value of 0.6 followed by culturing at 26 °C for 6 h. The production of glucaric acid substantially reached 5.24 ± 0.015 g·L−1in fed-batch cultures in a 30 L tank. In the present study, a new system for glucaric acid production was established, which was more economic and friendly to the environment.Keywords:urinate dehydrogenases;pETDuet-2 × Udh;D-glucaric acid;glucuronic acid;SDS-PAGE

To enhance the adsorption capacity of biochar (BC), herein a novel multifunction modified biochar (SDMBC) was prepared by directly crosslinking of the nanomicelle of sodium dodecyl sulfate/sapindus-saponin (SDS/SAP) composite system onto the BC through a simple, environmental friendly approach. Result showed that the adsorption performance of SDMBC has been greatly improved, compared with BC or using alone SDS and SAP, adsorption ability increased by 48.83%, 29.50%, 36.44%, respectively, the best modified effect was appeared when the concentration of SAP to SDS was 0.8 and 0.8 CMC. SDMBC exhibited high adsorption abilities of 130.23, 108.43, 277.09 125.27, 112.78 mg/g for heavy metal ions lead Pb(II), Cadmium Cd(II) and organic pollutants with different chemical properties bisphenol A(BPA), Methylene blue (MB), P-nitrophenol (PNP), respectively, higher than most previously reported adsorbents, importantly, SDMBC can still efficient removal capabilities even in the binary competition. Subsequently, the SDMBC and BC was characterized by Fourier Transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), scanning electron microscopy (SEM), Zeta potential (Zeta), it found SDMBC has a more layered structure, richer functional groups and more amorphous structure compared with BC, which are closely related with improving its adsorption capacity. The adsorption behavior of SDMBC for MB show that process was found to be spontaneous, propitious, endothermic, the adsorption isotherms fitted Freundlich models well, pseudo-second-order best describes kinetics adsorption, suggesting that the process is multi-layer chemical adsorption. The little affected by ionic strength and coexisting substances, could remained removal rate over a wide pH range, SDMBC still keep high removal rates even after 5 reuses. Based on FT-IR analysis, plausible adsorption mechanism proposed, including hydrogen bond, electrostatic attraction and π-π bonding. Cost analysis manifests that the SDMBC are high efficiency and cheap eco-adsorbents compared with commercial activated carbon, and the SDMBC dosage required for the removal of 99% of a fixed amount of MB in different volumes of effluent was predicted. Seven machine learning (ML) models were used to predict the MB (60 mg/L) adsorption of the SDMBC, using Shapley Additive Explanations (SHAP) for model interpretation. Finding Extreme Gradient Boosting (XGBoost) exhibited best performance, the order of feature importance as time> Ratio> pH> concentration> temperature. Thus, SDMBC as a new cheap and eco-adsorbents, can be used to effectively remove various types of pollutants, has a great application potential in sewage treatment, while the accurate ML prediction model presented a valuable advice for designing efficient adsorbents and optimization operating conditions in the future.

A biomass-derived surfactant system was developed from cardanol, enabling green and efficient waterborne modification of raw lacquer. • The optimal modification process achieved stable W/O → O/W phase inversion, realizing sprayable and water-dilutable lacquer. • The waterborne raw lacquer film showed a comprehensive improvement vs. RL, with adhesion and drying time significantly optimized. • Aqueous environment enhanced laccase activity and promoted C C bond-dominated cross-linking, forming a denser film network. • This strategy solves RL's poor processability, advancing the industrialization of high-performance sustainable coatings. Natural raw lacquer (RL), a high-performance natural coating, is severely limited in industrial application due to its high viscosity and stringent construction conditions. In this study, a green and efficient waterborne modification of RL was realized by compounding sodium pentadecylbenzenesulfonate (SPBS), synthesized from cardanol, with sodium dodecysulfonate (SDS) as composite surfactant, combined with ultrasonic dispersion. Single-factor and orthogonal experiments were optimized the preparation process, and the effects of modification parameters on waterborne raw lacquer (WRL) emulsion and film properties were characterized from Zeta potential analyze, FT-IR, LF-NMR and XPS. The optimal condition was 5.0% composite surfactant based on RL mass (mass ratio of SDS:SPBS = 25:75), 50.0% deionized water and 9 min ultrasonic treatment (120 W, 40 kHz). Under these conditions, WRL emulsion achieved a stable oil in water (O/W) phase with low viscosity and improved seven-day storage stability, enabling water dilution and spray coating. Compared with RL, WRL film presented a 56.2% improvement in comprehensive performance, with drying time shortened to 165 min, adhesion increased to 1.62 MPa, higher than three times of RL, and pencil hardness up to 4H, while maintaining a high wear resistance and thermal stability. LF-NMR confirmed WRL's higher cross-linking rate and density. The aqueous environment may facilitate laccase activity and ultrasonic treatment reduced particle size, jointly accelerating urushiol cross-linking and C C bond formation for a denser film network. This work solves RL's poor water dispersibility and construction difficulty, providing an experimental and theoretical support for high-performance eco-friendly WRL coatings.

Addressing water scarcity and agricultural sustainability under climate stress requires multifunctional materials with autonomous multisource hydration capable of harvesting moisture and supporting plant growth. Here, we report the development of a biodegradable, hydrogel composed of carboxymethyl cellulose (CMC), urea and CaCl 2 for integrated atmospheric water harvesting (AWH) and soil conditioning. Incorporation of sodium dodecyl sulfate (SDS) as a templating agent significantly enhanced the hydrogel's porosity and water uptake, as confirmed by SEM and BET surface analysis, which revealed increased pore volume, surface area, and morphological uniformity. The optimized CMCU@CaCl 2 hydrogel exhibited a high-water sorption capacity of 2.13 g/g at 90 % relative humidity and 25 °C, maintaining stable performance across 20–90 % RH. The condensed water met WHO purity standards, validating its suitability for agricultural applications. Agronomic trials demonstrated that the hydrogel extended maize plant survival from 7 to 20 days under drought conditions while maintaining comparable morphological traits to irrigated controls. Moreover, the hydrogel's ability to retain moisture and gradually release nitrogen improved soil water content and nutrient availability, enhancing drought resilience. This work introduces a cost-effective and scalable CMC-based hydrogel platform with strong potential for deployment in arid environments. Its dual function in autonomous multisource hydration and crop support offers a promising route toward sustainable agriculture and water management.

In this paper, the effects of sodium dodecyl sulfate (SDS) concentrations in the electroplating solution on the morphology, nucleation rate, nucleation mode, and frictional behavior of the CNT/Ni composite layers were investigated. The results showed that the electrodeposition of Ni was in a three-dimensional nucleation/growth mode. In addition, the x-ray diffraction (XRD) of the deposited layers showed that adding SDS changed the preferred growth direction of Ni from (2 0 0) to the (2 2 0) crystallographic plane. When the carbon nanotube (CNT) content was 0.1 g l−1, and the SDS content was 0.05 g l−1, the deposition potential was the most negative, increasing the number of Ni nucleation sites on the electrode and resulting in the grain size refinement of the deposited layer. It also reduced the friction coefficient of the composite simultaneously.

This study investigated the gelation of scallop male gonad hydrolysates (SMGHs) modified with sodium dodecyl sulfonate (SDS) and three polysaccharides, including κ -carrageenan (KC), ι -carrageenan (IC), and gellan gum (GG), and the film-forming properties were further evaluated. The transparency of SMGHs was improved by SDS in a dose-dependent manner, while the gel properties were disrupted. In this case, the gelling properties could be improved by introducing KC, IC, and GG, as reflected by 3.1–5.1 folds increment in G′ , 1.5–1.9 folds increment in hardness, 4%–6% increment in springiness, 19%–24% reduction in T 23 , and higher proton densities. In addition, the blueshift of SMGHs/SDS/polysaccharide amide II bands suggested increased electrostatic interactions within SMGHs and each polysaccharide. These scenarios could be ascribed to the compact and well-distributed network of SMGHs/SDS/polysaccharide. Furthermore, SMGHs-based ternary composite gels with desirable optical and mechanical properties could be applied as films in the food industry.

A glassy carbon electrode (GCE) modified with Mg-Al-SDS hydrotalcite-like clay (SDS-HTLC) was used for the sensitive voltammetric determination of 2-nitrophenol (2-NP) utilizing the oxidation process. The results indicate the prepared modified electrode has an excellent electrocatalytic activity toward 2-NP oxidation, lowering the oxidation overpotential and increasing the oxidation current. Under optimal conditions, the oxidation current was proportional to 2-NP concentration in the range from 1.0×10 −6 to 6.0×10 −4 M with the detection limit of 5.0×10 −7 M by DPV ( S / N =3). The fabricated electrode was applied for 2-NP determination in water samples and the recovery for these samples was from 95.6 to 103.5%.

In this paper, the feasibility was demonstrated to turn Liesegang patterned gelatin hydrogel into the multi-pulsed drug release system. Calcium hydrogen phosphate (CaHPO 4 ) crystals were selected as the Liesegang rings (LRs) materials. The structure of CaHPO 4 /gelatin was well tailored by adding the sodium dodecyl benzene sulfonate (SDBS) micelles or SDBS/cholesterol microcapsules. As a result, the completely isometric CaHPO 4 /gelatin LRs were prepared. The enzymolysis of gelatin with isometric LRs and cholesterol/SDBS microcapsules was carried out by using typsin. A stepwise kinetic curve of enzymolysis was obtained due to the obstacles of CaHPO 4 rings. This result indicated that CaHPO 4 /gelatin LRs were potentially a versatile platform for the multi-pulsed release of various drugs.

In this work, we propose a method to prepare anode materials for LIBs from alumina industrial waste red mud. The dispersed red mud with a sand-like morphology was obtained by an aicd pretreatment combined a SDS assist hydrothermal method. The as-prepared dispersed red mud electrode delivered a high discharge/charge capacity (1668.1 mAh g −1 at 0.1 A g −1 after 200 cycles) and an excellent long-cycle performance (460 mAh g −1 at 2.0 A g −1 after 360 cycles). The outstanding electrochemical performance of the dispersed red mud electrode can be attributed to the addition of SDS, which inhibits the agglomeration of iron oxide, reduces the volume change caused by the lithium intercalation/deintercalation process, and reduces the irreversible capacity. The SiO 2 and Al 2 O 3 scattered in the red mud also play a synergistic effect, alleviating the volume expansion during charging and discharging, and improving the cycle stability of the dispersed red mud. The application of red mud in anode materials for LIBs may provide an idea for the recycling of waste resources, reducing energy shortages and easing environmental pollution.

The thermodynamics of molecular self-assembling of an anionic biosurfactant, sodium cholate (NaCA) and its mixtures with sodium dodecyl sulfate (SDS) in aqueous solution have been investigated by isothermal titration calorimetry (ITC), along with fluorescence and conductivity measurements. Different critical concentrations were obtained by these three techniques – critical pre-micelle concentration (cmc pre ) and critical micelle concentration (cmc) for pure NaCA, and critical micelle concentrations (cmc mix ) for the mixed systems with differently initial SDS concentrations. Importantly, ITC allowed us to directly measure the enthalpy changes of pre-micelle formation (Δ H premic = (−0.28 ± 0.02) kJ·mol −1 ) and of micelle formation (Δ H mic = (−1.76 ± 0.05) kJ·mol −1 ) for pure NaCA as well as the enthalpies for micellization for the mixed systems NaCA/SDS. The non-ideality of the mixed surfactant solution was evaluated in terms of interaction parameters and excess enthalpies that were calculated in the light of Clint’s and Rubingh’s models. It was found that there is an obvious synergistic effect in the NaCA/SDS mixed system. From all these results we can ascribe the strong interaction between the same charge surfactants NaCA and SDS to the structural difference in their hydrophobic moieties. In fact, the flexible alkyl chains of SDS and the non-planar hydrophobic β -faces of NaCA tend to have a more compact packing than pure NaCA.

Bilayered sodium dodecyl sulfate (SDS)/ionic liquids (alkyl imidazolium type ionic liquid Cnmim+, n = 10, 12, 14, and 16) were first employed to modify the surface of Fe3O4 nanoparticles for the formation of stable aqueous ferrofluids. Subsequently, in the synthesized bilayered SDS/C16mim+-stabilized ferrofluid (Fe3O4/SDS/C16mim+), magnetic mesoporous silica with a cubic (Ia3d) mesostructure (Fe3O4@MCM-48) has been synthesized using tetraethylorthosilicate as the silicon source and the long chain C16mim+ as a template again. The research results showed that the combination of SDS and long chain Cnmim+ (such as C16mim+) is superior to that of SDS and short chain Cnmim+ (such as C10mim+) for the production of stable ferrofluids in water. Moreover, Fe3O4@MCM-48 (0.1 g) with Fe3O4 particles embedded in the network of cubic mesoporous silica showed decolorization rates of up to ∼90% in 25 min for four dye (methylene blue, rhodamine B, malachite green, and methyl violet) solutions (50 mL, 100 mg L−1). In addition, the malachite green-adsorbed Fe3O4@MCM-48 can be separated and recovered under an external magnetic field. This method in which the long chain ionic liquid C16mim+ can be manipulated in turn not only as the modifier but also as the mesoporous templating agent provides important guidelines for the multifunctional applications of C16mim+ in the synthesis of various nanostructured materials.

The illegal addition of drugs to health foods posed significant risks to consumer safety, prompting an urgent need for reliable monitoring methods. A simple, green, efficient dual-surfactant supramolecular solvent dispersion liquid-liquid microextraction coupled with high performance liquid chromatography (SUPRAS-DLLME-HPLC) method was developed to determine four sulfonylurea hypoglycemic drugs (glibenclamide, gliclazide, glimepiride, gliquidone) in health food. A low-viscosity, high-density supramolecular solvent (SUPRAS) was prepared from 1-butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide ([BMIM][TFSI]) and sodium dodecyl sulfate (SDS) by vortex-assisted two-step self-assembly. The incorporation of SDS into [BMIM][TFSI] significantly enhanced the SUPRAS extraction efficiency, and the surface morphology, microstructure, and physicochemical properties of SUPRAS were subsequently characterized. The four analytes showed good linearity (R 2 > 0.9994) in the range of 7.8–2000 μg kg −1 , with limits of detection and limits of quantification of 1.14–2.40 μg kg −1 and 3.82–8.03 μg kg −1 , respectively. The present method provided a practical and green solution for identifying illegal additives in health food.
