Utilization of graphite tailings and coal gangue in the preparation of foamed ceramics

AbstractTo enhance the effective utilization of graphite tailings and coal gangue (CG), both considered typical industrial solid waste materials, we synthesized foamed ceramics incorporating these materials. The optimization process led to improvements in compressive strength, water absorption, and thermal conductivity by regulating critical parameters, including the proportions of SiC and Na2O, as well as the duration of ball milling. Employing techniques such as X‐ray diffraction, thermogravimetric analysis, and differential scanning calorimetry, we investigated the phase composition, high‐temperature reactions, and microstructural characteristics of the foamed ceramics. The incorporation of graphite tailings (GT) facilitated the formation of a rich network of pore structures and amorphous glass phases, which enhanced the lightweight nature, mechanical strength, and thermal insulation properties of the foamed ceramics. By analyzing the GT content as a variable, we determined that the G50C40 (GT:CG:potassium feldspar = 40:50:10) sample exhibited optimal performance overall. Under these experimental conditions, the foamed ceramic demonstrated a bulk density of 0.749 g/cm3, a compressive strength of 12.37 MPa, a thermal conductivity of 0.21 W/(m·K), and a water absorption rate of 0.79%. Therefore, it is posited that GT possesses considerable potential to broaden the application spectrum of foamed ceramics within the domain of building insulation materials.

Improving the properties of clay soils in foundations through compaction and the integration of fibres and cement

Clay soils present significant challenges in engineering applications, particularly in the design and construction of foundations, due to their susceptibility to swelling and shrinkage. This research investigates the enhancement of clay soils through the incorporation of fibres, compaction, and cement, based on a comprehensive series of tests conducted at the Public Works Laboratory in Adrar, southern Algeria. The tests adhered strictly to technical standards in soil mechanics, examining the physical, mechanical, and thermal properties of the clay soil. The results demonstrated that applying a compressive strength of 2.5 MPa and incorporating palm and glass fibres in proportions ranging from 0% to 0.3% reduced bulk density by 0.95% to 7%. The capillary water absorption rate increased by 10.61% to 12.63%, while compressive strength improved by 11.4% to 34.37%. Furthermore, thermal conductivity decreased by 0.71% to 11.9%. These findings provide valuable insights into the properties of clay soils and the observed improvements. It can be concluded that soil enhancement through various materials and fibres is viable and yields positive outcomes in geotechnical applications.

Preparation of Expandable Polymer Plugging Agent and Its Application in Water‐Based Drilling Fluid

ABSTRACTIn order to reduce the economic loss caused by well leakage and the lag of drilling progress, it is very important to use plugging materials reasonably and effectively. Expandable polymer materials can better fill cracks and holes of different sizes by absorbing water expansion and deforming. In this article, an expandable polymer plugging agent (PSMAN) was prepared by soap‐free emulsion polymerization using methyl methacrylate (MMA), styrene (St), 2‐acrylamide‐2‐methylpropanesulfonic acid (AMPS) as reaction monomers, N‐hydroxymethyl acrylamide (NMA) as a cross‐linking agent, and ammonium persulfate (APS) as initiator. The optimal synthesis conditions were determined by designing the orthogonal experiments, and the various properties of the materials were tested and evaluated. The experimental results show that PSMAN has good high temperature resistance, spherical structure, and median particle size of 15.099 μm, and the water absorption rate of room temperature at 24 h reaches 37.8 g/g, and pressure bearing capacity can reach 5 MPa. The addition of polymer to water‐based drilling fluid can increase the viscosity of drilling fluid and improve the rheological properties of drilling fluid by a small amount. Under normal temperature and medium pressure, the polymer can form a dense film on the surface of the mud cake, thereby reducing the filtration of drilling fluid and effectively improving the stability of the wellbore.

Influence of silica fume on pore structure, mechanical properties and carbon emission of reactive powder concrete prepared by ice crystal homogenization technology

Under ultra-low water-to-binder ratio conditions, the liquid-bridge effect between powders seriously restricts the development of reactive powder concrete (RPC). Ice crystal homogenization technology fundamentally solves the liquid-bridge problem between powders. However, high carbon emissions still constrain the application of RPC. This paper introduces an innovative RPC material incorporating silica fume (SF) as a supplementary cementitious material to solve environmental concerns and alleviate powder aggregation challenges based on the ice crystal homogenization technology. Experimental results show that there was a significant improvement in compressive and flexural strengths observed, particularly in RPC material containing 15% SF, which exhibited the most notable enhancements: a 19.7% increase in compressive strength to 296.3MPa and a 23.6% increase in flexural strength to 43.8MPa. Moreover, the optimized microstructure was reflected in a substantial reduction in water absorption rate and cumulative pore volume by 44.7% and 54.4%, respectively. Besides, RPC incorporating 15% SF achieved the lowest carbon emissions efficiency, with carbon emissions efficiency could be reduced by 79%~93% compared with conventional UHPC. In conclusion, the use of SF and ice crystal homogenization technology in RPC provides the great potential for developing sustainable construction materials and promoting carbon reduction strategies.

All-natural, hydrophobic, biodegradable cellulose-based straws through simultaneous esterification and filling with stearic acid for cold beverages.

Disposable plastic straws have caused severe environmental pollution because microplastics produced in the degradation process harm human health and marine ecosystems. Paper straws as substitutes need to be incorporated into hydrophobic agents and other chemicals to achieve hydrophobicity, which may be harmful to human health. In this study, a novel and purely natural hydrophobic cellulose-based straw was made from bleached bamboo fibers (BBF) and stearic acid (SA). The prepared straw (BBF/SA@straw) exhibited improved hydrophobicity, biodegradability, and applicability. The water absorption rate was maintained at 58.66 % using single-factor analysis and response surface methodology and the maximum water contact angle was up to 133o. Additionally, the paper straw was almost completely degraded after 50 days in soil. Moreover, it could be used normally in water at 0 °C and 25 °C and was suitable for various beverages (tea, coffee, coke, and milk), demonstrating an extensive application prospect. This work supplies a promising and green alternative to plastic straws, alleviating the burden of white pollution in the environment.

A detailed insight into rate of water absorption of concrete: Experimental and modelling approach

A multifunctional bacterial cellulose-based dressing modified by quaternized chitosan and grafted protocatechuic acid for diabetic ulcer.

Herein, we developed a multifunctional bacterial cellulose-based dressing (PHBC) modified by quaternized chitosan (HACC) along with protocatechuic acid (PA), through in situ biosynthesis combined with covalent immobilization. The obtained PHBC dressing maintained the excellent physicochemical characteristics of BC, such as high porosity (above 76 %); high water absorption ratio, >80 % of water absorption rate (approximately 30 g/g) has completed in half an hour; favorable hydrophilicity with contact angle of about 50° and excellent flexibility. The introduction of PA-grafted HACC endows exhibited outstanding antibacterial properties against, anti-inflammatory performance and antioxidant capacity. Furthermore, PHBC II, with the reaction solubility of PA was 3 mg/mL, could promote NIH3T3 and HUVECs proliferation and spread. In vivo experiments further verified that PHBC II can effectively promote new granulation tissue hyperplasia and collagen deposition and expression around diabetic ulcers, reduce the inflammatory phenomenon around the wound, and promote the internal capillaries of the wound. The repair and regeneration of the network can promote better and faster wound healing. These results illustrate that the PHBC functional dressing has an important reference value for the clinical treatment of diabetic ulcers.

Study on the physical mechanical properties and freeze-thaw resistance of energy storage concrete with artificial phase change aggregate

As the main material for major infrastructure in cold regions, the mechanical properties and freeze-thaw resistance of concrete have become key scientific issues affecting the safety and normal operation and maintenance of infrastructure in cold regions. Energy storage concrete with phase change materials (PCM) has high thermal storage performance, which is beneficial to improving the frost resistance of concrete. In our preliminary research work, the artificial phase change aggregate (APCA) containing PCM with high latent heat, good mechanical properties and frost resistance were made and tested. The APCA was added to the concrete and replaced with natural coarse aggregate in different proportions, resulting in several energy storage concrete schemes with different APCA contents. The water absorption characteristics, microstructure and pore characteristics of energy storage concrete with different APCA contents were tested and analyzed through negative pressure saturation test, SEM and MIP. The effects of APCA replacement on the composition, mechanical properties, failure morphology characteristics and frost resistance durability of energy storage concrete at various ages were analyzed through XRD test, strength test and freeze-thaw cycle test. The results showed that replacing natural coarse aggregates with APCA changed the pore characteristics of concrete, reduced its saturation water absorption rate, but did not change the composition of hydration products at various ages of concrete. Replacing with an appropriate amount of APCA in concrete is beneficial for reducing the total porosity, the number of more-harmful pores and harmful pores. APCA reduce the compressive strength and splitting tensile strength of energy storage concrete at various ages. The early splitting strength of energy storage concrete increases rapidly, while the later growth is relatively slow. APCA are beneficial for suppressing the expansion of pores and cracks under freeze-thaw action of concrete. APCA is helpful to improve the freeze–thaw resistance of the energy storage concrete. After 100 freeze-thaw cycles, their strength is still 96% of the 28 day strength, and their compressive strength is about 35 MPa. This study provides a reliable experimental and theoretical basis for improving the freezing resistance of concrete in cold area.

Incorporation of polyvinyl alcohol in bacterial cellulose/polypyrrole flexible conductive films to enhance the mechanical and conductive performance

The integration of polypyrrole (PPy) into bacterial cellulose (BC) has provided significant conductivity and cost benefits. However, this combination has led to a reduction in mechanical properties, particularly in terms of elongation at break and tensile strength. This study investigated the enhancement of BC/PPy composite films by incorporating polyvinyl alcohol (PVA). The resulting BC/PPy/PVA films demonstrated improvements in flexibility, tensile strength and thermal stability. Specifically, with 7 % PVA, the flexible films exhibited remarkable enhancements: tensile strength increased from 11.01 MPa (for BC/PPy) to 25.27 MPa and elongation at break rose from 5.81 % to 11.54 %. Additionally, the electrical conductivity of the BC/PPy/PVA films with a resistance of 38.5 Ω, surpassed that of the BC/PPy films. Furthermore, the equilibrium swelling water absorption rates of BC/PPy and BC/PPy/PVA films were 30.6 % and 81.4 %, respectively, with corresponding resistances of 530 Ω and 540 Ω. The variation in resistance between the dry and swollen states of the BC/PPy/PVA flexible conductive film resulted in differences in the brightness of the small light bulb. These findings highlighted the synergistic effects of PVA within the BC/PPy matrix, presenting a promising avenue for developing high-performance conductive materials suitable for flexible electronics and wearable devices.

This study focuses on the utilization of iron ore tailings for synthesizing high-strength concrete aggregate as a sustainable alternative to conventional stone aggregates, which are often obtained through environmentally harmful quarrying practices. The research investigates the feasibility of producing high-strength ceramsite using iron ore tailings, fly ash, and bentonite as primary raw materials. Through a uniform design method, the study deeply explores the role of iron ore tailings. To understand the relationship between compressive strength and the components used, first- and second-order polynomial equations were developed and thoroughly analyzed using stepwise regression techniques. This approach enabled the optimization of material ratios, leading to the achievement of the desired results. Additionally, the study examines the impact of varying sintering temperatures on the compressive strength, density, and water absorption of the ceramsite. Under optimized conditions, the resulting ceramsite exhibited impressive properties, with an average compressive strength of 52.33MPa, an apparent density of 2,600kg/m³, and a water absorption rate of 0%. This research highlights the potential of iron ore tailings as a sustainable alternative in the construction industry, emphasizing the development of eco-friendly building materials while reducing environmental impacts.

Development and Optimization of Geopolymer-Based Artificial Angular Coarse Aggregate Using Cut-Blade Mechanism

This research introduces a novel approach to developing geopolymer-based artificial coarse aggregate using a cut-blade mechanism, providing an innovative approach to traditional aggregate. A modified concrete drum mixer equipped with additional cutting blades was employed to produce angular aggregates with consistent particle sizes ranging from 10mm to 20mm with rough surface texture. Compared to conventional techniques, this method ensures a more uniform aggregate shape, enhancing its mechanical interlocking properties in construction applications. The experimental results demonstrated abrasion values between (13.2% to 31.5%), impact value test (9.8% to 21.6%), water absorption rates of (2.62% to 4.2%), and specific gravity values ranging from (1.18 to 2.2). To further optimize the alkali activator dosage, a mathematical model was developed using the ANOVA test and Response surface methodology (RSM), achieving high regression predictive accuracy with R2 values > 0.93. The model demonstrated optimal results between experimental results and predicted results for specific gravity, impact value, abrasion value, and water absorption. Microstructural analysis via Scanning electron microscopy (SEM) reveals optimal pore distribution inside aggregates, while X-ray Fluorescence identifies significant intensities of Quartz, Ettringite, and calcium silicate hydrate gel. Overall, this research not only demonstrates the technical feasibility of producing high-performance artificial aggregate from waste materials but also underscores its potential to mitigate environmental impacts and promote sustainable construction practices.

Fabrication of an antibacterial hydrocolloid dressing for the management of wound infection caused by antibiotic-resistant bacteria: In Vitro study

The purpose of this study was to fabricate an antibacterial hydrocolloid dressing for the management of infected wounds with multidrug-resistant (MDR) bacteria. Among hospitalized patients, infections caused by MDR bacteria are a major cause of morbidity and mortality, especially in burn units. A hydrocolloid dressing was fabricated using pectin, gelatin, and sodium carboxymethyl cellulose as well as 16, 32, and 64 mg/ml of CM11 antibacterial peptide. After the characterization of the hydrocolloid dressing, its antibacterial activity against MDR strains of Pseudomonas aeruginosa, Staphylococcus aureus, and Escherichia coli was investigated. The optimal cross-linking duration using glutaraldehyde vapor was three hours, resulting in a degradation of 28 % after 48 hours. SEM showed the uniform structure of the fabricated dressings. The Young's modulus, tensile strength, and elongation at break were 19 kPa, 0.041 MPa, and 180 %, respectively. The water absorption and water vapor transmission rates were 149 % and 464 g/m2/day. The peptide release assay showed that more than 25 % of the peptide was released during 24 hours. The antibacterial activity of the hydrocolloid was dose-dependent, with the highest inhibitory effect at a concentration of 64 µg/ml. Based on the time-killing assay, the peptide in a dose-dependent manner caused a decrease in CFU of the three bacteria after the first 6 hours compared to the control (without treatment) and the dressing without peptide (p ≤ 0.05). However, at a concentration of 64 µg/ml, this reduction was present for up to 24 hours. The results showed that the antibacterial hydrocolloid dressing can be considered as a wound dressing candidate to deal with wound infections.

Liquid-Water Transfer Coefficients of Porous Building Materials Under High-Humidity Conditions

The moisture transfer coefficient is a key parameter for analyzing the moisture-based physical properties of materials and studying the heat–moisture coupling process within building envelopes. The liquid-water transfer coefficient, as an important aspect of this process, plays a significant role, especially under high-humidity conditions. However, the global research on liquid-water transfer coefficients is still far from complete. To further enhance the research on liquid-water transfer coefficients, this study conducted capillary water absorption experiments on seven traditional and new porous building materials, focusing on testing the moisture transfer coefficients, primarily the liquid-water transfer coefficient. A novel analysis regarding the impact of sealing materials was proposed, based on the experimental results. Based on the experimental data, the concept of a critical value related to the variation in the capillary moisture content and the liquid-water diffusion coefficient was raised, and, building upon traditional empirical models, a completely new computational model was proposed. Data processing was carried out using methods such as variability analysis, correlation analysis, and nonlinear regression for model fitting. The research findings indicate the following: (1) The capillary water absorption rate and capacity of a material are influenced by its density and porosity. (2) In terms of sealing materials, self-adhesive films performed better than non-adhesive films. (3) The concept of critical capillary moisture content was proposed, based on the rate of change in the liquid-water diffusion coefficient. For the threshold of w ≤ 80%, a new calculation model with a higher correlation coefficient was proposed which can meet the calculation requirements of the diffusion coefficient under the vast majority of relative-humidity conditions.

Synthesis and characterization of polyacrylamide-based antibacterial hydrogel nanocomposite

ABSTRACT In this research, the hydrogel nanocomposites based on acryl amide containing penicillin 800, 1200, Ag, and ZnO nanoparticles as wound dressing applications have been studied. In this work, the preparation was done via a reaction of optimal values to produce an antibacterial hydrogel nanocomposite. The hydrogel was obtained in an aqueous medium by using reagents such as acrylamide, potassium persulfate, and methylene bisacrylamide crosslinker, Ag, ZnO nanoparticles, and penicillins and then, the products were dried as white powders. The properties such as swelling rate, pH sensitivity, and high water swelling capacity of the swelling rate study of the hydrogel showed a high absorption rate of water in pH about 3–4. The effect of temperature on the percentage of hydrogel swelling was shown to swell with increasing temperature and the absorption capacity of polyacrylamide hydrogels decreased with increasing NaCl concentration. The chemical structure of hydrogel was confirmed by FTIR spectrum, and the morphology of synthesized hydrogel surfaces was studied via SEM. The antibacterial studies were done in blood, agar, chocolate, and Müller medium via three methods, first on gram-negative bacteria E. coli and Klebsiella, second in urine medium, and third in drug medium. This polymeric blend can be used as a new wound dressing compound.

Synthesis and application of Aromatic Schiff base waterborne polyurethane as visible-light triggered self-healing polymer and anticorrosion coating using h-BN/GO/NiO nano-composite

Herein, a self-healing waterborne polyurethane (WPU) based on a novel visible light-stimulated healing agent from the aromatic Schiff base family (SBWPU) was synthesized. Moreover, this polymer exhibited remarkable mechanical properties, making it an ideal matrix for the preparation of a new nano-composite coating using hexagonal-boron nitride/graphene oxide/nickel oxide (h-BN/GO/NiO) nano-composite for anti-corrosion applications. SBWPU containing 15 wt % of synthesized healing agent (SBWPU-15) demonstrated favorable healing properties (80.03 %) under a visible light lamp after 24 h (at ambient temperature). SBWPU containing 20 % of the healing agent (SBWPU-20) showed high mechanical properties (20.80 MPa) and an increase in its hydrophobic properties. Additionally, its water absorption rate decreased, making it an attractive option as a polymer matrix for anti-corrosion coating applications. The nano-composite coatings (CSBWPU) were formulated by introducing varying amounts of h-BN/GO/NiO into the SBWPU-20. The coatings displayed an increase in contact angle and a decrease in water absorption rate. The electrochemical impedance spectroscopy (EIS) results revealed that the 0.75-CSBWPU, containing 0.75 % nano-composite, had the highest corrosion resistance (1.58 × 1010 Ω cm2) after 90 days of immersion in seawater. This work offers a potentially helpful concept for developing an eco-friendly, secure, uncomplicated accessibility self-healing polymeric system with controllable mechanical features, which are also favorable for designing novel corrosion protection composite coatings.

Study on the corona aging characteristics of KH570-modified nano-Al(OH)₃ cycloaliphatic epoxy resin in hygrothermal environments

Cycloaliphatic epoxy(CE) resin may experience insulation degradation and pose a threat to the safe operation of equipment when used in high-temperature and high-humidity environment. Therefore, to enhance the corona aging resistance of CE under harsh conditions, this study incorporated γ-methacryloxypropyltrimethoxysilane-modified (KH570) nano-Al(OH)₃ with varying content into the CE. The samples were subjected to corona aging tests under different hygrothermal conditions. The corona aging characteristics of CE in high-temperature and high-humidity environments were analyzed using scanning electron microscopy(SEM), Fourier transform infrared spectroscopy(FTIR), resistivity, and dielectric loss measurements before and after modification. The results indicate that as humidity increases, the unmodified samples develop pores and cracks on the surface, which leads to an increased water absorption rate and internal hydrolysis. However, with the increase in filler content, the water absorption channels on the sample surface decrease, effectively suppressing chemical moisture absorption and maintaining the stability of the internal chemical structure. Among the various filler contents, the effect was most pronounced at 3%wtCE. Under 65 % RH conditions, the volume/surface resistivity increased by 27.28 % and 26.9 %, respectively, the leakage current decreased by 64.85 %, while the dry and wet breakdown voltages increased by 9.3 kV and 6.85 kV, respectively, and the dielectric loss variation with humidity was reduced. Compared to the unmodified material, KH570-modified nano-Al(OH)₃ has significantly improved the insulation and aging resistance properties of the material under hot and humid corona aging conditions. This study provides a reference for improving the performance of epoxy resins under high temperature, high humidity, and strong electric field conditions.

Effect of freezing and freezing-thawing pretreatment on wood properties and drying characteristics of Eucalyptus urophylla × E. grandis

ABSTRACT Eucalyptus wood has uneven density and poor permeability, which can lead to defects such as wrinkling and cracking during the drying process, limiting applications. Freezing and freeze–thaw treatments can improve wood permeability by disrupting its microstructure, thus enhancing drying quality. In this experiment, Eucalyptus urophylla × E. grandis was subjected to cold trap freezing (CF), refrigerator freezing (RF), cold trap freeze–thaw (CFT), and refrigerator freeze–thaw (RFT) pretreatments. The pretreated materials were then dried and tested to investigate properties such as permeability, moisture absorption, shrinkage, and drying characteristics. The results indicated that the moisture content (MC) during pre-freezing, with lower freezing temperatures leading to greater reductions in MC. The water absorption rates for the CF, RF, CFT, and RFT pretreated wood increased by 16%, 7%, 16%, and 14%, respectively, showing significant improvement in permeability, which in turn resulted in increased drying rates of 24%, 11%, 26%, and 13%, respectively, when the MC exceeded the fiber saturation point (FSP). The shrinkage ratios were reduced by 8%, 2%, 4%, and 8%, respectively, but increased the equilibrium moisture content (EMC) by 5% for all groups. Overall, the improvement in drying rate from freeze–thaw treatment was greater than that from freezing treatment.

Reactive hyperbranched core-shell architecture for developing high-performance bio-based adhesive

Soybean meal (SM) adhesives offer a promising alternative to formaldehyde-based adhesives; however, their broader application is hindered by suboptimal adhesive properties and inadequate water resistance. In this study, we designed a novel reactive core-shell architecture (DAS@HBPA/EP) composed of dialdehyde starch (DAS) as the core and hyperbranched epoxy (HBPA/EP) as the shell, aimed at developing an SM adhesive with excellent water resistance, high bonding strength, and superior toughness. The reactive shell of DAS@HBPA/EP formed covalent bonds with protein molecules in SM, creating a highly interconnected structure that enhanced both the adhesive properties and water resistance of SM. Additionally, the microphase separation induced by the DAS core and the flexible hyperbranched shell provided the SM adhesive with improved toughness. As a result, plywood bonded with the SM/DAS@HBPA/EP adhesive exhibited exceptional dry shear strength (up to 2.14 MPa) and wet shear strength (1.24 MPa), representing a 589 % improvement over the pure SM adhesive. This performance is comparable to commercial melamine-urea-formaldehyde (MUF) resins (E0 grade). Furthermore, the SM/DAS@HBPA/EP adhesive showed a high residue rate (82.30 %) and low water absorption rate (0.94 %), along with a uniform and dense microstructure. This simple and cost-effective strategy presents a novel approach to advancing technological innovation in the development of multifunctional composite materials.

Thymoquinone Pectin Beads Produced via Electrospray: Enhancing Oral Targeted Delivery for Colorectal Cancer Therapy.

Background/Objectives: Thymoquinone (TQ) exhibits diverse biological activities, but its poor solubility and bioavailability limit its cancer efficacy, requiring innovative solutions. This study explores the development of an oral delivery system targeting colon cancer based on TQ pectin beads (TQ-PBs) produced through an adjustable electrospray technique. This study hypothesised that adjusting bead diameter through the electrospray technique enables precise control over water absorption and erosion rates, thereby achieving a controlled release profile for encapsulated TQ, which enhances targeted delivery to the colon. Methods: TQ-PBs were synthesised and optimised using an electrospray technique based on the ionic gelation method. The prepared beads were characterised based on particle size, sphericity, encapsulation efficiency (EE), water uptake, erosion, surface morphology, molecular interactions, and texture. The cumulative TQ release studies, an accelerated stability test, and cytotoxicity evaluation against the colon cancer HT-29 cell line were also assessed. Results: The optimised TQ-PB formulation demonstrated an average bead size of 2.05 ± 0.14 mm, a sphericity of 0.96 ± 0.05, and an EE of 90.32 ± 1.04%. The water uptake was 287.55 ± 10.14% in simulated gastric fluid (SGF), 462.15 ± 12.73% in simulated intestinal fluid (SIF), and 772.41 ± 13.03% in simulated colonic fluid (SCF), with an erosion rate of 45.23 ± 5.22%. TQ release was minimal in SGF (8.13 ± 1.94% after 2 h), controlled in SIF (29.35 ± 3.65% after 4 h), and accelerated in SCF (94.43 ± 2.4% after 3 h). Stability studies over one month showed a size reduction of 17.50% and a 6.59% decrease in TQ content. Cytotoxicity assessments revealed significant anticancer activity of TQ-PB, with an IC50 of 80.59 ± 2.2 μg/mL. Conclusions: These findings underscore the potential of TQ-PB as an effective oral drug delivery system for targeted colorectal cancer therapy.
