Techniques to acquire chiral information from molecules are essential for deciphering important biological processes and improving the performance of industrial chiral materials. Herein, we report novel supramolecular gelators that enable widely accessible chiral supramolecular organogels for simple naked-eye enantiodifferentiation of specific enantiomers (left- or right-handedness) for wide-range substances. The supramolecular gelators featuring multiple hydrogen-bonding sites and large π-π conjugated groups are produced by complexing commercially available chiral tartaric acids and achiral 1-naphthylmethylamine. The highly polar and insoluble acid-amine complexes drive the aggregation of the supramolecular gelators, which further form chiral nanofibers due to chirality transfer from tartaric acid to the supramolecular nanofibers through multiple hydrogen-bonding between the hydroxyl groups of chiral tartaric acids and π-π stacking between 1-naphthylmethylamine molecules. At high concentrations, physical crosslinking of the chiral nanofibers creates a chiral gel structure that facilitates interactions between its chirally and non-covalently associated components and enantiomers, making the gel system particularly sensitive to specific types of enantiomers. Consequently, sensitive naked-eye detection of specific enantiomers of diverse substances is achieved via observing “gel-to-micelle” transitions, which occurs when the enantiomers generate complexes that disrupt chirality transfer in the co-assembly and destroy the hierarchical structures. © 2023

Zeolitic imidazolate framework (ZIF-67) with high surface area and tunable pore size are considered as a promising active material for energy storage, but the low electrical conductivity restricts its performance. Developing ZIF67 derivatives with improved electrical conductivity is necessary to broaden its application in electrochemical fields. In this work, two strategies are applied to improve electrical conductivity and electrochemical performance of ZIF67. Novel structure directing agents of NH4BF4 and NH4HF2 are used to synthesize ZIF67 derivatives with higher theoretical capacitances and favorable layered structures. Self-assembled MXene with different amounts is further incorporated in ZIF67 derivatives to establish composites. The optimal composite electrode shows a high specific capacitance (CF) of 1410.4 F/g (775.6C/g) at 20 mV/s, while the ZIF67 derivative electrode without MXene only shows a CF value of 942.3 F/g (518.3C/g), due to the high surface area and better pore structure as well as the close combination of MXene and the layered ZIF67 derivative for the former case. An energy storage device with the optimal composite and carbon electrodes shows the maximum energy density of 32.40 Wh/kg at 375 W/kg. The Coulombic efficiency of 100% and the CF retention of 77.4% are also achieved after 10,000 cycles. © 2024 Elsevier Ltd

Iron oxide (Fe2O3) with a high theoretical capacitance, wide potential ranges and easy availability has attracted much attentions as the electrode material of battery supercapacitor hybrids (BSH). Metal–organic framework (MOF) is one of the promising potential energy storage materials due to its large surface area and controllable pore structures. In this work, novel iron oxide/iron organic framework composites (Fe2O3/FeMOF) are in-situ grown on the Ni foam as efficient energy storage electrodes of BSH. By tuning the solvothermal durations, the morphology changes from random sizes of sheets, regular grown vertical sheets, to flower-like structures. The d-spacing also increases for the Fe2O3/FeMOF synthesized using longer solvothermal durations. The optimal Fe2O3/FeMOF electrode synthesized using 9 h shows a high areal capacitance of 10.97 F/cm2 along with an areal capacity of 5.49 F/cm2 at the current density of 35 mA/cm2, owing to the most regular growth of sheets, the large d-spacing, and the smallest charge-transfer resistances. A BSH composed of the Fe2O3/FeMOF positive electrode and a graphene negative electrode shows a maximum energy density of 0.76 mWh/cm2 at 22.5 mW/cm2. The excellent long-term cycling stability with the capacitance retention of 85% and Coulombic efficiency of 98% are also achieved after 10,000 charge/discharge cycles. © 2024 Elsevier Ltd

Nickel-based compounds are widely applied as the active material for energy storage devices, owing to high theoretical capacity and easy-fabricated process. Bimetallic compounds having multiple redox states can provide abundant redox reactions for charge storage. Structure directing agent (SDA) can promote the preferable growth of active materials and to enhance energy storage abilities. In this work, NH4BF4 and NH4HF2 are firstly used as SDA to synthesize nickel-based compounds along with 2-methylmidozole in the one-step solution process for energy storage applications. The bimetallic compounds are synthesized by incorporating Al, Mn, Co, Cu and Zn salts in the precursor solution including the Ni salt. The system with Al, Cu or Zn possesses single metal compound and barely nickel compound. Mn and Co-incorporated systems present clear bimetallic components with nickel hydroxide. The highest specific capacitance (CF) of 1336.3 F/g (297.0 mAh/g) are achieved at 20 mV/s for the NiCo-based electrode, owing to the bimetallic feature and favorable two-dimensional sheet-like structures. An energy storage device is assembled using the NiCo-based compound and reduced graphene oxide electrodes. The maximum energy density of 10.5 Wh/kg at 0.3 kW/kg, and the CF retention of 78.5% and Coulombic efficiency of 85.2% are achieved after 10,000 times charge/discharge cycles. © 2023 Elsevier Ltd

Low water solubility leading to poor bioavailability has an impact on the decreasing of curcumin uptake in the body, resulting in a deficiency of its medicinal benefits. This study aims to overcome the limitations of curcumin by formulating a nano-emulsion called curcumin emulsion (CE). Furthermore, in order to improve the physicochemical properties and drug release features, the CE was encapsulated within chitosan-assembled mesoporous silica nanoparticles (Chi@SiO2@CE). This material was prepared using a one-pot method and was characterized by ATR-FTIR, PSA, TGA, N2 adsorption-desorption, SEM, and TEM. Additionally, antioxidant activity and in vitro drug release were also conducted. The study demonstrated that CE has strong antioxidant activity (IC50 = 14.14 µM) compared to curcumin alone. Additionally, the Chi@SiO2@CE exhibited pH-controlled release behavior, with less than 20% release of curcumin under an artificial gastric environment and 50% release under pH 7.4 conditions within 24 hours. Therefore, this research suggest that Chi@SiO2@CE material has potential as a pH-responsive drug delivery material. © 2023, The Authors. All rights reserved.

Isolated Pt atoms tethered to N-doped MoSx as highly efficient and sustainable hydrogen evolution reaction electrocatalyst

In this work, synergistic NH4+ intercalation and nitrogen-containing molecule doping realize a crystalline-to-amorphous (i.e., MoSx) structure transition with enhanced HER reactivity and superior stability obtained via structural distortion and abundant active sites. The applied N dopants partially replace the bridging S22− and form Mo-N bonds, where the alkyl N-dopant tetramethylammonium chloride (TEA) achieves the most effective doping. The HER activity increases with an increasing number of bridging S22− and MoⅤ species, both of which contribute to advance electrocatalytic performance. Furthermore, N-doped MoSx is identified as an exceptional stabilizing platform to anchor single Pt atoms (PtSA) through Pt-S bonding, rendering MoSx/TEA/PtSA a highly promising electrocatalyst. MoSx/TEA/PtSA achieved comparable performance to that of the benchmark Pt/C catalyst (i.e., a cathodic current density of 10 mA·cm−2 at overpotential of 97 mV) with much lower loading of Pt (0.67 wt%). Theoretical calculations based on density functional theory indicate that Pt atoms and Pt-adjacent sulfur atoms act as active sites. The superior interfacial electron transfer and thus HER performance of MoSx/TEA/PtSA arises from (1) boosted electronic metal-support interaction through Pt-S bonds and (2) enhanced H adsorption ability of Pt-adjacent sulfur atoms due to Pt coordination. © 2022 Elsevier B.V.

The development of flexible strain sensors with multidimensional sensing and physiotherapy abilities simultaneously is brilliant for the advancement of wearable sensing electronics. Herein, a composite hydrogel with anisotropic electromechanical properties and excellent magnetothermal capabilities was developed based on a magnetic field pre-induction strategy. Specifically, the as-developed two-dimensional Fe3O4@MXene nanohybrids were induced to be orientationally aligned within the polyvinyl alcohol (PVA) network for conductive hydrogels with anisotropic topology structures. Due to the as-optimized composite hydrogel exhibiting different conductivities in parallel and vertical directions, it can be developed into a multidimensional strain sensor, which is suitable for strain sensing in orthogonal directions with distinguishable gauge factors (such as GF = 3.20, while GF⊥ = 1.78 in the tensile strain range of 0 ~ 60%) and relatively fast response time (t = 74.47 ms, t⊥ = 157.63 ms). Furthermore, the composite conductive hydrogels can also be assembled into a 3D distribution array for detecting the magnitude and spatial distribution of stress. In addition, it also exhibits excellent magnetothermal physiotherapy capabilities. In summary, it is a promising candidate for next-generation multidimensional flexible sensors with rehabilitation assistant functions. © 2023, The Authors. All rights reserved.

According to several researchers reporting, it was reported that organic pollutants dissolved in water were increasing. One of these increasing pollutants is aspirin. Our study aimed to remove aspirin in pharmaceutical wastewater by electrocoagulation, using an aluminum plate (15 cm x 4 cm x 0.5 cm) as an anode and a carbon plate (15 cm x 4 cm x 0.5 cm) as a cathode. Aspirin-containing organic pollutant samples (artificial) were prepared by dissolving aspirin purchased from a pharmacy in distilled water of varying concentrations. Before and after the sample is purified by the electrocoagulation process, its character is measured. pH, color, chemical oxygen demand (COD), turbidity, density, and conductivity were measured. The differences in the character of organic pollutants (aspirin) before and after electrocoagulation were explained from various points of view, such as electrode distance, initial pH, current density, and contact time. The kinetic processes that occur are also observed and reported. Indicators of soluble aspirin pollutants, such as pH, color, turbidity, density, and conductivity, decreased significantly. Furthermore, the dissolved aspirin pollutant was associated with research variables such as electrode distance, initial pH, current density, and contact time. Electrocoagulation can be considered an alternative method to treat wastewater containing aspirin pollutants. © 2022 science Press. All rights reserved.

The kitchen waste compost treatment of diesel contaminated soil has the advantages of good bioremediation effect and low treatment cost. However, through understanding the mechanism of microbial degradation of diesel, the disadvantage of biological treatment time in the composting process is too time-consuming. The research results showed that the evolution of microbial communities was affected by physicochemical parameters in the composting process. During the heating period, it was found that Lactobacillus sakei and Escherichia coli were acid producing bacteria. Pseudomonas putida GB-1 is a terpenoid producing bacterium. Bacillus sp. was found to be aldehyde and sulfide producing bacteria during high temperature composting. Brevibacillus borstenensis and Low G + C Gram positive bacteria are ammonia producing bacteria. The microbial degradation mechanism could be deduced according to the VOCs change in compost gas, and the strategies to promote the efficiency of biological treatment in the composting process were provided for reference. © 2023 Elsevier Ltd

Because of the harsh environmental impacts of fossil fuels, price fluctuation, and resource limitation, renewable energy resources (RERs) are considered the ultimate solution to overcome these challenges. RERs are also abundant and environmentally friendly. It has been reported that the growth rates in renewable energy installations have increased by 8–9% annually since 2010, reaching a cumulative capacity of 2.9 TW by 2020 and exceeding the growth rate for fossil resources. In this work, the different RERs have been critically discussed in terms of their operation principles, advantages, disadvantages, and associated environmental impacts, focusing on wind and solar energies as the most deployed RERs. Barriers to the full deployment of RERs to replace fossil resources are discussed. Based on the discussion presented on RERs, the contribution of deploying RERs towards the achievement of the United Nations (UN) Sustainable Development Goals (SDGs) is also critically discussed. A total of 80 indicators have been identified for RERs' contribution toward the achievement of SDGs. © 2023 The Author(s)
