Realization of a Two-Dimensional Checkerboard Lattice in Monolayer Cu2N

Two-dimensional checkerboard lattice, the simplest line-graph lattice, has been intensively studied as a toy model, while material design and synthesis remain elusive. Here, we report theoretical prediction and experimental realization of the checkerboard lattice in monolayer Cu2N. Experimentally, monolayer Cu2N can be realized in the well-known N/Cu(100) and N/Cu(111) systems that were previously mistakenly believed to be insulators. Combined angle-resolved photoemission spectroscopy measurements, first-principles calculations, and tight-binding analysis show that both systems host checkerboard-derived hole pockets near the Fermi level. In addition, monolayer Cu2N has outstanding stability in air and organic solvents, which is crucial for further device applications.

Flexible and ultrathin GO@MXene sandwich-type multilayered film toward superior electromagnetic interference shielding in a wide gigahertz range of 3.95–18.0 GHz

Conductive MXene-based films are potential in electromagnetic interference (EMI) shielding. However, multilayered MXene-based films are rarely reported, and the EMI shielding investigations are confined in only X band (8–12 GHz). Herein, sandwich-type multilayered [email protected] films were constructed by an alternating vacuum-assisted filtration technique. Benefiting from interlayer scattering and high conductivity, the flexible multilayered [email protected] films show excellent EMI shielding performance in 3.95–18.0 GHz at an ultrathin film thickness. The mechanical properties and EMI shielding performance are related to the layered structure, film thickness and content of MXene. Especially, the trilaminar [email protected] film (only ∼8 µm) shows superior EMI shielding and mechanical properties. The average EMI shielding effectiveness (SE) values are 44.5, 46.6 and 45.0 dB at C, X and Ku bands, respectively, with the corresponding specific EMI SE values of 22,429.4, 23,487.9 and 22,681.5 dB cm2 g−1. The [email protected] film exhibits remarkable stability in acid, alkaline and organic solvent. This work not only provides a flexible film with high EMI shielding performance at a wide gigahertz range, but also suggests that the mechanical properties and EMI shielding can be tuned by simply changing the layered structure. This is helpful to give guidance to the design of novel MXene-based EMI shielding films and expand their applications.

Stable tetranuclear copper cage as efficient heterogeneous catalyst for C−C and C−N bond forming reactions

Two tetranuclear copper cages with tubular type, [Cu4(BMBA)4((CH3)2N)2(H2O)2] (1) and [Cu4(BMBA)4(Bipy)(H2O)2] (2), were successfully constructed by the reaction of Cu(NO3)2 with dicarboxylic acid 4,4′-[(ethylazanediyl)bis(methylene)]-bis[(1,1′-biphenyl)-2-carboxylic acid] (H2BMBA) under solvothermal conditions. The complexes 1 and 2 exhibit a similar cage structure, formed by four ligands connecting two binuclear copper paddle-wheel secondary building units (SBUs). Interestingly, the complex 2 was obtained by appropriately binding of 4, 4′-bipyridine (Bipy) molecule on the axial positions of two Cu paddle-wheels inside the cage. For this reason, the complex 2 exhibits excellent stability in some common organic solvents at room temperature and aqueous solutions with a pH of 2 to 12. Upon thermal activation of complex 2, the coordinated water molecules can be removed, and its exposed metal active-sites show Lewis acid character, which can be used an efficient heterogeneous catalysis of Knoevenagel condensation (CC) and Clauson-Kaas (CN) reactions.

Au/CeO2 NR Restricted Inside Cu-MOFs: A Three-in-One Artificial Enzyme with Synergistically Enhanced Peroxidase-Like Activity for Dual-Mode Sensing of Multiple Biomarkers

Nanomaterials with inherent enzyme-mimetic properties have been extensively studied in biosensing field, but it is still challenging to overcome their natively weak enzyme-mimetic activity and further promote their stabilities. In this work, a three-in-one artificial enzyme with synergistically enhanced peroxidase-like activity and outstanding stability is constructed by restricting Au-loaded CeO2 nanorods (NR) (1% Au:CeO2 mass ratio) inside Cu-based metal–organic frameworks (Cu(PABA)), termed Au1/CeO2 NR@Cu(PABA). It has been demonstrated that the artificial enzyme possesses significantly improved performance in catalytic decomposition of H2O2, with ∼2.41 and ∼1.49 times higher activity than its individual constituents (Au1/CeO2 NR and Cu(PABA)), benefiting from the synergistic effect and the unique restricted structure; owns strong affinities to substrates, with separately ∼8.21- and ∼3.13-fold lower Michaelis constants toward H2O2 and o-phenylenediamine, respectively, than horseradish peroxidase; and exhibits desirable pH (4–12), thermal (30–80 °C), organic solvent (N,N-dimethylformamide, acetone, methanol, etc.), and long-term storage (30 days) stabilities, advantaging practical applications. Taking aforementioned superior properties of Au1/CeO2 NR@Cu(PABA), a universal colorimetric/fluorometric dual-mode sensing platform is built and utilized for detection of biomarkers (e.g., glucose, galactose, and cholesterol) in biological fluids with satisfactory recoveries (90.2–108%). This work offers new horizons in designing high-efficiency, stable, and credible biomimetic catalysts to accelerate future advanced engineering of nanozymes.

Temperature Dependent Hydrogen Bond Toward High Emission in an Emerging Indium-Based Perovskite.

Low-dimensional organic-inorganic hybrid perovskites (OIHPs) with broadband emission attract immense scientific interest due to their potential application for the next generation of solid-state lighting. However, due to low exciton utilization, organic cations generally adjust structure rather than contribute the band edge to affect optical properties. Based on this, OIHPs are usually allowed to obtain a low photoluminescence quantum yield (PLQY). Herein, a good charge transfer carrier (p-phenylenediamine, PPDA) as organic cation is rationally employed and a novel indium-based perovskite is synthesized. By coupling with H2 O molecules, a strong interaction between organic and inorganic components is realized by hydrogen bonding, which has good transportability and greatly improves the exciton utilization. The regions of hydrogen bonding show high electron mobility, combined with the induced recombination center, improving the progress of charge relaxation. As a result, the regulation of hydrogen bond strength based on the microstructure optimization directly determines the optical emission intensity, realizing nearly 100% PLQY. Further, the polyhydrogen bond structure makes each component a stronger interaction, showing high stability in polar, organic, and acidic solvent, as well as long-term storing, which represents one of the highest overall performances for lighting in OIHPs.

Industrial applications of fungal lipases: a review.

Fungal lipases (triacylglycerol acyl hydrolases EC 3.1.1.3) are significant industrial enzymes and have several applications in a number of industries and fields. Fungal lipases are found in several species of fungi and yeast. These enzymes are carboxylic acid esterases, categorized under the serine hydrolase family, and do not require any cofactor during the catalyzing of the reactions. It was also noticed that processes including the extraction and purification of lipases from fungi are comparatively easier and cheaper than other sources of lipases. In addition, fungal lipases have been classified into three chief classes, namely, GX, GGGX, and Y. Fungal lipases have applications not only in the hydrolysis of fats and oils (triglycerides) but are also involved in synthetic reactions such as esterification, acidolysis, alcoholysis, interesterification, and aminolysis. The production and activity of fungal lipases are highly affected by the carbon source, nitrogen source, temperature, pH, metal ions, surfactants, and moisture content. Therefore, fungal lipases have several industrial and biotechnological applications in many fields such as biodiesel production, ester synthesis, production of biodegradable biopolymers, formulations of cosmetics and personal care products, detergent manufacturing, degreasing of leather, pulp and paper production, textile industry, biosensor development, and drug formulations and as a diagnostic tool in the medical sector, biodegradation of esters, and bioremediation of wastewater. The immobilization of fungal lipases onto different carriers also helps in improving the catalytic activities and efficiencies of lipases by increasing thermal and ionic stability (in organic solvents, high pH, and temperature), being easy to recycle, and inducing the volume-specific loading of the enzyme onto the support, and thus, these features have proved to be appropriate for use as biocatalysts in different sectors.

Insight into the influences of thermal crosslinking on the transition from polyacrylonitrile based ultrafiltration membrane to organic solvent nanofiltration membrane

In this work, polyacrylonitrile (PAN) based organic solvent nanofiltration (OSN) membranes were prepared by combining nonsolvent-induced phase separation (NIPS) and thermal crosslinking methods. The structure and morphology changes of the PAN membrane during thermal crosslinking were investigated by Fourier transform infrared spectrometer (FTIR), X-ray photoelectron spectrometer (XPS), X-ray diffractometer (XRD) and scanning electron microscope (SEM). The thermal crosslinking reaction of PAN chains and fusion of pore structure occurred simultaneously, which were conducive to the transformation of an asymmetric PAN ultrafiltration (UF) membrane into OSN membrane. The influences of thermal crosslinking temperature and time on the structure evolutions and nanofiltration performance of PAN based crosslinked membranes were systematically investigated. The formation mechanisms of OSN membrane were discussed in terms of the evolutions of chemical structure and pore structure. The resultant thermally crosslinked membranes showed excellent thermal stability and solvent resistance in different organic solvents. Furthermore, a remarkable stability of OSN performances in long-term test was exhibited due to the formation of crosslinked ladder structure of PAN. This work showed that thermal crosslinking is an encouraging and promising method to transform UF membranes into OSN membranes.

Noncovalently functionalized boron nitride nanotubes and polymer nanocomposites with water-soluble poly (amic acid) salt

In this study, polyamic acid salt-BNNTs (PAS-BNNTs) were prepared by noncovalently functionalizing water-soluble PAS with improved dispersion stability in organic solvents, and high compatibility with polyimide (PI) nanocomposites. We show that BNNTs functionalized with PAS have enhanced mechanical properties that are influenced by various loadings of PAS-BNNT/PI films through in situ polymerization. Compared with the pure PI film, the tensile strength and tensile modulus increased by about 20% and 37%, respectively. The proposed system also improved the coefficient of thermal expansion (CTE) from 52.6 to 45.7 ppm/oC. The enhanced mechanical properties of the PI nanocomposite were due to the interfacial bond strength enhanced by the reinforcing effect of PAS-BNNTs. Our study demonstrates the potential of PAS-BNNTs for preparing BNNT/PI nanocomposites with various structures.

Rational design of peptides for biomimetic palladium nanoparticle catalysis with Suzuki and Heck coupling in ethanol

Peptide-mediated nanoparticle synthesis has been shown as an environmentally friendly way to synthesize highly reactive nanocatalysts. Previous studies have shown that peptides are capable of controlling the size and shape of metal nanoparticles made from Pd, Au, Pt, and Ag. These studies revealed that the sequence of the amino acids is critically important to optimize the performance as nanocatalysts. However, these peptide-mediated formations of nanoparticles are limited to aqueous solvents. There is a need for such optimized catalysts in organic solvents. For this, a palladium-binding peptide was modified to contain hydrophobic sequences to improve the stability and reactivity in organic solvents. Palladium nanoparticles were synthesized using the modified peptides in ethanol and used as catalysts in Suzuki and Heck coupling at a catalytic loading of 0.05 mol% at room temperature or 80 °C. The location of the hydrophobic region was found to be pivotal for increased reactivity.

Highly porous ultrathin polyamide membranes for fast separation of small molecules from organic solvents

Membranes with permselective performance as well as high stability in harsh solvents are urgently desired for energy-efficient precise chemical separations. In this work, we utilize an adamantane diamine as a molecular building block to fabricate thin-film composite polyamide membranes for high-performance organic solvent nanofiltration (OSN). The bulky, cage-like adamantane structure acts as a molecular-level steric hindrance unit to inhibit polymer chain packing which generating interconnected micropores within the interfacially polymerized polyamide layer. This translates into high membrane methanol permeance of 20.6 L m-2 h-1 bar-1 and 94.7% retention to organic dye molecules with molecular weight down to 327 g mol-1. Furthermore, the membrane demonstrates high stability in different organic solvents taking advantage of the crosslinked rigid structure, which shows constant solute retention throughout a 180 h continuous filtration experiment with a DMF solution containing methyl orange as feed solution. Employing rigid and bulky molecular features in selective layer is thus demonstrated to significantly promote the polyamide membrane permeability and solvent resistance without compromising the overall selectivity.

Organic solvent nanofiltration with nanoparticles aggregation based on electrostatic interaction for molecular separation

Organic solvent nanofiltration (OSN) has been regarded as a promising membrane-based separation technology with great potential in many fields. In this work, based on the strong electrostatic interaction between nanoparticles (NPs) prepared by the quaternized P(VC-r-DMAEMA) (Q-PVD) and hydrolyzed polyacrylonitrile (HPAN) substrate membranes, separation nanochannels were successfully constructed on the surface of membranes by a one-step coating method. The types of the substrates and concentrations of NPs were optimized to obtain the proper performance. The surface morphology, chemical compositions, surface wettability, surface charge, and pore size were characterized. The obtained thin-film nanocomposite (TFN) membranes exhibited excellent stability in various common organic solvents, such as n-heptane, acetonitrile, ethanol, etc. Furthermore, composite membranes showed excellent retention for dyes with specific molecular weights, with a molecular weight cut-off (MWCO) of 825 Da. In particular, the rejection rates of Coomassie brilliant blue (BB) and Bengal rose red (RB) were 96.6% and 97.9%, respectively. Given the above characteristics, the composite membranes are expected to be used in the field of OSN.

Structure and Properties of a Mixed-Ligand Co-MOF That Was Synthesized in Situ from a Single Imidazole–Pyridyl–Tetrazole Trifunctional Ligand

A mixed-ligand Co-MOF (SCNU-Z7) based on a new imidazole–pyridyl–tetrazole trifunctional ligand, 3-(imidazol-1-yl)-5-(tetrazol-5-yl) pyridine (HITP), was constructed using a solvothermal reaction. Single-crystal X-ray diffraction analysis revealed that in addition to HITP, the 5,5′-bis-(2H-tetrazol-5-yl)-[3,3′]bipyridinyl (H2BTBP) ligand obtained by the in situ reaction of HITP is also incorporated into the framework, thus generating a mixed-ligand metal–organic framework (MOF). SCNU-Z7 has a 3D porous framework with 1D channels along the c axis based on tetranuclear secondary building blocks and has a new highly (3,4,10)-connected network topology with the symbol (416·620·89)(43)2(44·62). SCNU-Z7 exhibits high stability in organic solvents but instability in water. Gas adsorption studies indicated that SCNU-Z7 can absorb CO2 more than N2. Magnetic studies indicate the existence of dominant antiferromagnetic interactions between Co(II) atoms. Due to porosity, Co(II) ions, nitrogen-rich conjugated aromatic rings, and uncoordinated nitrogen atoms in its framework, SCNU-Z7 can capture iodine in vapor with a capacity of 2.7 g/g. The strong interactions between the framework and the iodine molecules cause the amorphization of the framework, and approximately 60% of the adsorbed iodine molecules can be stably stored in the framework. This study provides a new possible route for obtaining mixed-ligand MOFs and provides a new example for stably capturing iodine in MOFs via amorphization.

Intelligent pH-responsive PMIA membrane with reversible wettability for controllable oil/water and emulsion separation

Intelligent membrane with reversible wettability is an ideal strategy for oil/water separation, but there are still limitations of the reality application of oil/water separation. This effort produced a distinctive, intelligent, pH-sensitive oil/water separation membrane. Modified silica (SiO2-OTES), low-budget titanic oxide (TiO2), decanoic acid (DA), pollution-free chitosan (CTS), and Poly (m-phthaloyl-m-phenylenediamine) (PMIA) are selected to combine to form a superhydrophobic SO@TDC/PM membrane. The wettability of the modified membrane is reversible under the different effects of ammonia treatment and heat treatment. Also, the intelligent membrane is used to achieve controllable separation of oil/water mixtures, and to effectively separate various oil-in-water emulsions and water-in-oil emulsions before and after wettability conversion. In addition, the intelligent membrane has excellent self-cleaning ability, a high separation flux, and high separation efficiency. At the same time, the intelligent membrane itself has good organic solvent, storage, and mechanical stability. The results show that SO@TDC/PM membrane has good reversible wettability, which provides a broad prospect for the development of intelligent response materials with reversible wettability.

Intermolecular cross-linked polymer of intrinsic microporosity-1 (PIM-1)-based thin-film composite hollow fiber membrane for organic solvent nanofiltration

Organic solvent nanofiltration (OSN) is a membrane-based organic solution separation process that has emerged as a viable alternative to energy- and solvent-intensive separation processes. Polymers of intrinsic microporosity (PIMs) are the targets of recent active research on OSN membrane materials because of their unique physicochemical properties, such as solution processability, chemical tunability, robust porosity, and high thermal stability. However, applying PIMs-based membranes in practical OSN applications is still challenging because of their limited organic solvent stability and inevitable decrease in performance. Meanwhile, despite the potential of thin-film composite hollow fiber membranes for OSN, only a few studies have been reported to date. In this study, we fabricated a PIMs-based thin-film composite hollow fiber membrane by dip-coating and improved its organic solvent stability by intermolecular cross-linking. The membrane exhibited pure ethanol permeance of 10.9 LMH/bar and a molecular weight cut-off of 952 g/mol in ethanol. The membrane displayed stable dye rejection performance (>95%) even after immersion in ethanol, acetone, and toluene for seven days. This study demonstrates that intermolecular cross-linking between PIMs polymer chains can improve the organic solvent stability of PIMs-based membranes and provides a desirable strategy to fabricate feasible organic solvent stable PIMs-based thin-film composite hollow fiber membranes for OSN applications.

Lanthanide-MOFs as multi-responsive photoluminescence sensor for sensitively detecting Fe3+, Cr2O72- and nitrofuran antibiotics.

Fast and selective detection of contaminants plays a key role in meeting human health and environmental concerns. Herein, two groups of isostructural lanthanide MOFs, [Ln(Hpta)(oxalic acid)]·H2O (1-Eu, 2-Gd) and [Ln(pta)(oxalic acid)0.5(H2O)2]·2H2O (3-Eu, 4-Gd) (H2pta = 2-(4-pyridyl)-terephthalic acid, C2O4- = oxalic acid), were synthesized by solvothermal method. Single crystal X-ray diffraction reveals that 1 and 2 are 3D neutral frameworks, while 3 and 4 consist of 2D layers with parallelogram holes and stack into 3D networks through O-H⋯N and O-H⋯O hydrogen bonding interactions. All complexes remain crystalline and stable below 400 °C, suggesting preeminent thermostability. Noteworthily, only 3 shows excellent chemical stability in water and organic solvent. Therefore, the solid-state fluorescence spectrum was used to characterize 3 which exhibited intense red luminescence. The N active sites in the pore channels of 3 are conducive to displaying a distinct quenching effect for Fe3+ cations in aqueous solutions, Cr2O72- anions in DMF and DMA solutions, and nitrofuran antibiotics in the DMF solvent. Overall, 3 is a prospective luminescent sensor for detecting Fe3+, Cr2O72- and nitrofuran antibiotics.

Chiral lanthanide-silver(I) cluster-based metal-organic frameworks exhibiting solvent stability, and tunable photoluminescence.

Due to the lack of effective synthetic strategies, the preparation of chemically stable chiral Ag(I) cluster-based materials for assembly remains challenging. Here, we have developed an approach to synthesize three pairs of chiral Ln-Ag(I) cluster-based metal-organic frameworks (MOFs) named l-LnAg5-3D (Ln = Gd for 1-L, Eu for 2-L, and Tb for 3-L) and d-LnAg5-3D (Ln = Gd for 1-D, Eu for 2-D, and Tb for 3-D) by employing a chiral Ag(I) cluster ({Ag5S6}) as the node and Ln3+ ion as the inorganic linker. Structural analysis revealed that the chiral ligands induced chirality through the entire structure, resulting in a chiral helix arrangement of the C3-symmetric chiral {Ag5S6} nodes and Ln3+ ions. These compounds showed high solvent stability in various polar organic solvents. The solid-state circular dichroism (CD) spectra of compounds l-LnAg5-3D and d-LnAg5-3D exhibited obvious mirror symmetrical peaks. The emission spectra in the solid state revealed that compound 1-L only exhibited the emission peak of {Ag5S6}, while compounds 2-L and 3-L exhibited overlapping peaks of Ln3+ and {Ag5S6} at different excitation wavelengths. This demonstrates the tunable photoluminescence from {Ag5S6} to Ln3+ by introducing different Ln3+ ions and manipulating the excitation wavelengths. The study underscores the enhanced stability of Ag(I) cluster-based MOFs achieved through the incorporation of Ln3+ ions and establishes chiral Ln-Ag(I) cluster-based MOFs as promising candidates for advanced materials with tunable photoluminescence.

A Robust Molecular Porous Material for C2 H2 /CO2 Separation.

A molecular porous material, MPM-2, comprised of cationic [Ni2 (AlF6 )(pzH)8 (H2 O)2 ] and anionic [Ni2 Al2 F11 (pzH)8 (H2 O)2 ] complexes that generate a charge-assisted hydrogen-bonded network with pcu topology is reported. The packing in MPM-2 is sustained by multiple interionic hydrogen bonding interactions that afford ultramicroporous channels between dense layers of anionic units. MPM-2 is found to exhibit excellent stability in water (>1year). Unlike most hydrogen-bonded organic frameworks which typically show poor stability in organic solvents, MPM-2 exhibited excellent stability with respect to various organic solvents for at least two days. MPM-2 is found to be permanently porous with gas sorption isotherms at 298K revealing a strong affinity for C2 H2 over CO2 thanks to a high (ΔQst )AC [Qst (C2 H2 ) - Qst (CO2 )] of 13.7kJ mol-1 at low coverage. Dynamic column breakthrough experiments on MPM-2 demonstrated the separation of C2 H2 from a 1:1 C2 H2 /CO2 mixture at 298 K with effluent CO2 purity of 99.995% and C2 H2 purity of >95% after temperature-programmed desorption. C-H···F interactions between C2 H2 molecules and F atoms of AlF6 3- are found to enable high selectivity toward C2 H2 , as determined by density functional theory simulations.

Effect of attaching hydrophilic oligopeptides to the C-terminus of organic solvent-tolerant metal-free bromoperoxidase BPO-A1 from Streptomyces aureofaciens on organic solvent-stability

Metal-free bromoperoxidase BPO-A1 from Streptomyces aureofacience was selected among several similar enzymes exhibiting brominating activity as the most stable haloperoxidase against 70%(v/v) methanol. A comparison of the BPO-A1 and octahistidine-tagged BPO-A1 at the C-terminus (BPO-A1-His8) revealed that the His-tag enhanced the organic solvent-stability of BPO-A1 with pH- and heat-stabilities. Additionally, the contribution of the hydrophilicity at the C-terminal of BPO-A1 to the organic solvent-stability was confirmed employing several mutants bearing hydrophilic oligopeptides. Fortunately, two excellent mutants, BPO-A1-Lys8 and BPO-A1-Arg8, with high stabilities against various water-miscible organic solvents were obtained. In conclusion, the enhancing effect of the hydrophilic oligopeptides on the organic solvent-stability was associated with a decrease in the hydrophobic surface area near the C-terminus.

Organic quaternary phosphonium salts intercalated MXene towards controllable amphiphilicity and dispersions

• 1. Ti 3 C 2 was intercalated by quaternary phosphonium salt with different structure. • 2. The modified Ti 3 C 2 show controllable dispersions in different organic solvents. • 3. The thermal stability of Ti 3 C 2 was significantly improved after the intercalation. Two-dimensional Ti 3 C 2 has drawn widespread academic interest in several fields due to its unique physicochemical properties. However, its poor dispersion in organic solvents and easily oxidized in aqueous solution pose a challenge to storage and application. Herein, we intercalated Ti 3 C 2 with a series of quaternary phosphonium salts (QPS) for turning amphiphilicity, thus controlling its dispersion in organic solvents. The effect of molecular structure of QPS on the dispersion of modified Ti 3 C 2 was investigated, including chain type and length. The results showed that the thermal stability and dispersion in organic solvents of Ti 3 C 2 were remarkably enhanced after being intercalated with QPS containing a longer chain. This strategy may pave a new way for rationally designing Ti 3 C 2 with high stability and dispersion and enriching its application.

Nanofiltration membranes composed of carbonized giant cane and Pongamia meal binder for ion sieving in water and molecular sieving in organic solvents

Climate change and other environmental problems necessitate the use of renewable resources and the development of sustainable technologies. Thus, giant cane, which is naturally abundant, and a plant-based binder extracted from Millettia pinnata seeds were used to fabricate carbon-based composite membranes. A continuous and uniform layer of a carbonized giant cane was formed on a porous support using a simple filtration method. The hardness of the membranes increased with the carbon content. The increase in the carbon content in the membrane yielded a looser and more selective nanofiltration membrane; the water permeance increased from 13 to 19 L m−2 h−1 bar−1 and the NaCl/MgSO4 selectivity doubled from 10 to 20. Similarly, the rejection of five different salts and seven organic molecules decreased in water and acetone, respectively. The acetone permeance and molecular weight cutoff increased from 7 to 12 L m−2 h−1 bar−1 and from 577 to 795 g mol−1, respectively. The long-term performance tests on the membranes indicated a stable rejection of higher than 99% for rose bengal and a stable steady-state flux over a week of continuous filtration. The membranes exhibited good stability and high permeance in different organic solvents, including a harsh polar aprotic solvent, i.e., N,N-dimethylformamide. The toxicity of the giant cane carbon and the binder was examined via a cytotoxicity assay using NIH 3T3 cells. No toxicity was observed for either material. This study proposes a sustainable route for preparing aqueous and organic solvent nanofiltration membranes using natural nontoxic resources.
