Anti-corrosion and anti-biofouling CaCO 3 -based SLIPSs are constructed on Mg alloy. • All SLIPSs own highly stable surface hydrophobicity than hydrophobic surface under static and dynamic conditions. • SSO and FSO-infused coatings exhibited much better mechanical stability in terms of hydrophobicity. • SSO-infused coating possesses the highest corrosion resistance for Mg substrate. • All SLIPSs can effectively inhibit the adhesion of microorganisms on the surface. Magnesium and its alloys exhibit unique advantages in mechanical properties due to the low density and high specific strength. However, fast corrosion and poor resistance to biofouling largely limit their extensive applications. In this study, a multi-layer protective strategy is proposed, composed of a calcium carbonate porous bottom layer, a hydrophobic surface (HS) via modification and a slippery liquid-infused porous surface (SLIPS). This composite structure can remarkably inhibit the penetration of corrosive media and maintain the stability of surface hydrophobicity owning to the retention of infused oil into porous CaCO 3 coating and the physical barrier against corrosive solution. The results revealed that the static water contact angle of SLIPS-coated Mg alloy exceeds 90°, demonstrating excellent hydrophobicity. Meanwhile, stability tests and electrochemical measurements verified significantly improved corrosion resistance for SLIPS samples than the bare substrate, and the SLIPSs can maintain long-term hydrophobic performance in simulated seawater. Bacterial adhesion assays demonstrated that the coverage rates of E. coli and S. aureus on the SLIPSs dropped below 0.25%, revealing a remarkably anti-biofouling ability. These presented results provide an innovative solution and implementation approach for maintaining the long-term corrosion resistance and anti-biofouling stability for Mg alloys.

Thermochemical energy storage (TCES) under direct irradiation mode is a promising technology that promotes the widespread utilization of high-temperature concentrated solar energy. However, poor cyclic stability and solar absorption for calcium carbonates, high cost for cobalt oxides, and safety issues for powder-form materials hinder the practical applications of the TCES systems. This work innovatively proposed a compressed reactive TCES unit composed of 10%-volume of modified Co 3 O 4 in the center and 90%-volume of modified CaCO 3 around the center. The modified calcium-based compacted material (CaCO 3 M-p) exhibits 20.5°C lower onset temperature, 13.9 kJ mol −1 lower activation energy, and faster kinetics than the commercial CaCO 3 powder (CaCO 3 -u) in the energy storage process. Both the cyclic stability in 15 cycles and solar absorption of the CaCO 3 M-p are boosted, which are 1.25 times and 18.3 times those of the CaCO 3 -u, respectively. While compaction reduces the reactive performances by narrowing the porous, the Mn/Mg co-modification has a more significant effect in increasing the above properties by creating lattice defects and introducing impurities. The modified cobalt-based compacted material (Co 3 O 4 M2-p) presents similar reactive and optical properties as raw Co 3 O 4 powder, yet it elevates the average conversion rate in 30 cycles to 1.75 times that of compressed raw Co 3 O 4 . Modification by microcrystalline cellulose is the key to this improvement, as it reduces activation energy and promotes decomposition kinetics for compacted Co-based materials. The compressed reactive TCES unit demonstrates outstanding energy storage density and power. The 10%-volume Co 3 O 4 improves external radiation absorption and reinforces internal heat transfer, enhancing the unit’s energy storage rate. Moreover, Co 3 O 4 also contributes to energy density, raising the total density to 0.4217 MWh m −3 , exceeding the 0.2468 MWh m −3 limit of CaCO 3 powder. The compacted materials and composite unit advance the practical use of TCES in solar energy storage.

The development of inert additive-doped CaO-based CO 2 adsorbents is a promising method to obtain efficient CO 2 adsorbents, while multiple programs are frequently involved, the organic solvent is often used, and CO 2 is sometimes released in the process of preparation. In this study, we first report that inert additive-doped CaO-based adsorbents can be synthesized in one pot by the mechanochemical hydrogenation reduction of CaCO 3 producing methane and avoiding CO 2 emission. The prepared CaO@C and CaO@MgO@C composites are high-performance CO 2 adsorbents with high CO 2 adsorption capacity and superior cycling stability. The results show that the CO 2 capture capacities of the CaO@C and CaO@MgO@C composites are 19.14 and 14.53 wt% higher than that of the BM-CaO (37.07 wt%), respectively, at 650 °C carbonation for 2 h. Notably, the activity losses of the CaO@C and CaO@MgO@C composites after 30 cycles are about 47.93 and 29.33%, which are much lower than that of the BM-CaO (60.39%). The performance of the CaO@C and CaO@MgO@C adsorbents is comparable to that of adsorbents synthesized by the conventional methods, but this work provides novel, simple, solution-free, and sustainable strategies to synthesize effective CaO-based CO 2 adsorbents in one pot.

The CaCO 3 /CaO based thermochemical system has great potential in Concentrating Solar Power (CSP) plants. However, the CaCO 3 suffers from high sintering speed, poor thermal conductivity , and weak light absorption, which is not conducive to being directly driven by solar energy. Herein, The Mn and Cr elements were doped into CaCO 3 through the sol-gel method. The synergistic effect between the two elements can maintain the storage density at 1057.3 kJ/kg after 20 cycles at 800 °C. The light absorption under AM 1.5G spectrum was obviously improved to 64.5% and reached 73.3% after 20 cycles. To further improve the thermal conductivity of the composite, the tetrapod-shaped zinc oxide whiskers (TZnO) were directly mixed into the composite. The TZnO acts as the thermal conductance bridge in the composites and can retain its original morphology at high temperatures without reacting with CaCO 3 . When 5% mole ratio of TZnO was added to the Cr/Mn doped CaCO 3 , the thermal conductivity increased by 17.8%. Through the non-isothermal analysis of the reaction kinetics, it is found that the addition of TZnO can effectively accelerate the reaction, especially at a higher heating rate, which is very beneficial to direct solar-driven applications. The optimized composites showed excellent properties in light absorption, sintering resistance, thermal conductivity, and reaction kinetics, which can guide the direct photothermal utilization of CaCO 3 .

Ultraviolet (UV) absorbers are of vital importance in reducing the damage of UV irradiation to materials, incredibly effective in delaying the life of polymers. However, commercial inorganic UV absorbers tend to generate free radicals that accelerate the decomposition of materials. The carbon dots (CDs) that mineralize CaCO3 to different degrees to prepare excellent UV absorbers with UV absorption properties were proposed in this work. CDs with a negative charge of −3.77 mV and a surface rich in functional groups such as −COOH, −OH, −NH2, and −C═O were synthesized by a one-step method to induce the typical rhombic CaCO3 to form other irregular morphologies, including polycrystalline rhombic, flower-like, flower-like with more petals, and smooth spherical shapes. The UV absorption properties of CDs endow CaCO3 with a strong UV absorption capacity at 200–400 nm and the stability of spherical CDs@CaCO3 is higher than that of pure CDs. It shows that spherical CDs@CaCO3 have superior dispersibility, optical stability, high-temperature resistance, and anti-photoaging performance. Finally, to reflect the practical application of CDs@CaCO3, it was compounded with polyurethane (PU). It increases the UV resistance and mechanical properties of PU film, and the application of light conversion film has great potential in agriculture. The development of a new inorganic UV absorber has excellent prospects for application in the field of UV resistance.

A novel ultrasensitive electrochemiluminescence (ECL) immunoassay based on Au/CaCO3 was proposed for detecting ochratoxin A (OTA) in coffee. Au/CaCO3 nanocomposites synthesized using waste eggshells as the template with a large surface area and excellent electrochemical properties were applied for immobilizing a large amount of Ru(bpy)32+ and conjugating a high-affinity nanobody (prepared by the phage display technique). Coupling of the Au/CaCO3 nanocomposites and nanobody technologies provided an ultrasensitive and highly selective ECL immunosensor for OTA detection in the range of 10 pg/mL–100 ng/mL with a low detection limit of 5.7 pg/mL. Moreover, the as-prepared ECL immunosensor showed excellent performance and high stability. Finally, the proposed ECL sensor was applied to analyze OTA in coffee samples, confirming the desirable accuracy and practical applicability potential. Overall, this work presents a new nanomaterial for fabricating the sensing interface of immunosensors by harnessing natural waste as the source and a method for detecting toxic OTA in foods.

A novel nano-CaCO3 (nCaCO3) particle composite-derived polystyrene (PS) resin was successfully synthesized by a suspension polymerization method. The nCaCO3 reinforced PS material (PS/nCaCO3) possessed a structure with abundant mesopores of high porosity, high specific surface area (828.3 m2 g−1) and large pore volume (1.83 cm3 g−1). It was revealed that the incorporation of nCaCO3 into the PS matrix enhanced both the mechanical strength which can prevent the fragmentation and its adsorption capacity for interleukin-6 (IL-6, MW = 24.0 kDa) from human plasma. The adsorption isotherm could be described by the Langmuir model and classified as S-3 type, showing an IL-6 uptake of up to 25.6 ng g−1 at an equilibrium concentration of about 500 ng L−1. The adsorption capacity for IL-6 of PS/nCaCO3 is not only significantly higher than that of PS (without nCaCO3), but also superior to those of currently available adsorbents that are under clinical studies (e.g., CytoSorb™ towards cytokines). In addition, the PS/nCaCO3 adsorbent also had good hemocompatibility and showed no leakage of nCaCO3 in the plasma in a flowing model system. Therefore, the synthesized PS/nCaCO3 nano-composite has a great potential to be used as an efficient adsorbent for the removal of interleukin-6 (IL-6) from blood of inflammatory and auto-immune disease patients through hemoperfusion.

Paper emerges as an ideal substrate for flexible piezoresistive pressure sensors (PRSs) due to its inherent flexibility, cost-effectiveness, renewability, and lightweight properties. However, the intrinsic hydrophilicity of original paper poses substantial challenges for practical sensor applications. Herein, we coated Ti 3 C 2 T x @ZIF-8@PDA@AgNPs (TZPA) and PDMS/CaCO 3 on the surface of paper by facile spray-coating technique to prepare paper-based superhydrophobic flexible PRSs. By employing a bioinspired micro-cracked architecture derived from crustacean sensory systems, the sensor exhibited exceptional sensing properties: three linear sensitivity regions (S 1 = 1.36 kPa −1 , 0–3 kPa; S 2 = 8.71 kPa −1 , 3–10 kPa; S 3 = 0.81 kPa −1 , 10–30 kPa), rapid response/recovery times (98.1/97.9 ms), and stable operation over 500 cycles. The superhydrophobic PDMS/CaCO 3 layer, with its micro-nano structure and low surface energy, imparted the paper-based sensor with excellent waterproofing (water contact angle ∼151.1° and water sliding angle ∼9°), self-cleaning, and synergistic antibacterial properties when combined with the TZPA layer. Finally, the fabricated paper-based PRS demonstrated real-time detection capabilities for human bodily motions (including large/small movements) even under high-moisture conditions and underwater. Presented here is an environmentally friendly and simple method for fabricating superhydrophobic paper-based PRSs which have significant potential in the fields of wearable electronics, healthcare surveillance and human–computer interaction, even in aqueous environments.

Three-dimensional (3D) printed monolithic catalysts/adsorbents have attracted much attention due to their excellent properties. Herein, the rice husk-derived nitrogen-doped biochar (using urea as the nitrogen dopant) was printed into monolithic adsorbents using direct ink writing technology, and then assembled as agitating paddles for organic dye adsorption. To reduce the over-embedding of active sites in the polymeric matrix, CaCO 3 particles in nano-sized or micron-sized were added as sacrificial pore generators to form macropores and expose active sites, leading to an enhanced mass transfer efficiency. Material characterization results confirm the self-sacrificial role of CaCO 3 . The 3D-printed adsorbents with micron-sized CaCO 3 (denoted as 3D-HRSCCm) possessed excellent adsorption performance, as evidenced by a high adsorption capacity and kinetics study. Meanwhile, 3D-HRSCCm adsorbents were mounted as agitating impellers which demonstrated excellent reusability with the adsorption efficiency remaining above 90% after ten cycles. Furthermore, the 3D-HRSCCm exhibited excellent adsorption properties for various dyes such as methylene blue, rhodamine B, crystal violet, and malachite green. Moreover, the numerical simulation confirms that the introduction of CaCO 3 as a pore generator improved diffusion by providing wider channels and facilitated the mass transfer that accelerated the adsorption rates.

CaO/CaCO 3 heat storage is considered a promising technology to solve the intermittency of solar energy. Fluidized-bed reactor is commonly used as calciner/carbonator to efficiently achieve heat storage. In the fluidized-bed reactor, the particle cohesion impedes fluidization of CaO/CaCO 3 particles, adversely impacting heat storage. However, the current research rarely focuses on the cohesive behavior of CaO-based particles in fluidization during CaO/CaCO 3 heat storage process. Furthermore, current research on cohesive behavior primarily focuses on experimental studies, lacking an explanation of the underlying mechanisms at the molecular level. In this work, the cohesive behavior of CaO-based particles in CaO/CaCO 3 heat storage process was studied on a fluidized-bed reactor. The particle cohesion is reflected by the tensile yield strength during the transition from static state to fluidization state. The results indicate that the cohesive behavior of CaCO 3 particles gradually is strengthened with increasing temperature. The tensile yield strength of CaCO 3 particles at 800 °C is 1770 Pa, which is 200 % higher than that at 500 °C. Additionally, the carbonation enhances the cohesive behavior of CaO particles. The tensile yield strength of CaO particles after the carbonation is 55 % higher than that of before the carbonation. The enhanced cohesive behavior of CaO particles during the carbonation results in the defluidization. Molecular dynamics simulation shows that the formation of sintering necks at above 650 °C in the carbonation stage results in cohesive behavior of CaO particles. The introduction of 5 % Al 2 O 3 fines (50–75 μm) as lubricant effectively improves the fluidization quality of CaO particles in the carbonation stage, thereby enhancing the exothermic performance of CaO particles. These findings provide valuable insights for the industrial application of CaO/CaCO 3 heat storage in fluidization.

Compatibilizers allow for the combination of two materials with vastly different polarities. The dosage of most compatibilizers must be more than 5 wt% to be effective—an expensive high dosage level that changes polymer composite properties. Thus, in this study, renewable resource epoxidized soybean oil (ESO) was used as the raw material to synthesize the end-hydroxyl group bio-based compatibilizer ESO-g-S-HPG. The experimental results revealed that composites prepared with ESO-g-S-HPG had better mechanical properties (i.e., tensile strength , impact strength , and energy storage modulus) than those prepared with a commercially available compatibilizer (TA 1618). The addition of 1 wt% of ESO-g-S-HPG significantly enhanced the interfacial compatibility between the HDPE and CaCO 3 , making it a good candidate for application in the field of HDPE composite filling and reinforcement, as evidenced by the minimal voids revealed by the scanning electron microscopy results. The molecular dynamics simulation results revealed that hyperbranched compatibilizers can eliminate filler aggregation and enhanced filler-matrix interaction, yielding effects that are better than those of linear compatibilizers. The compatibilizer proposed here can be a useful material for the fabrication of the next generation of composites applied in diverse industrial fields.

Phenylboronic acid-functionalized nanometer-sized CaCO 3 particles (PBA-CaCO 3 ) were designed to determine the carcinoembryonic antigen (CEA) glycoprotein with a portable Ca 2+ ion-selective electrode (Ca-ISE) through a typical boronate ester bond. CaCO 3 nanospheres were conjugated to 3-aminophenylboronic acid by amine-epoxy reaction, whereas target CEA was captured into the aptasensing interface by the immobilized thiolated aptamer on gold substrate. Upon PBA-CaCO 3 introduction, 3-aminophenylboronic acid labeled to CaCO 3 microsphere specifically recognized with CEA glycoprotein based on sugar-boronic acid interaction to form a sandwiched complex. The carried CaCO 3 was dissolved under acidic conditions to release Ca 2+ ion with a portable Ca-ISE readout. Thanks to the specific boronate ester bond between PBA and 1,2-diols, the synthesized PBA-CaCO 3 exhibited good conjugation properties for CEA glycoprotein. Under optimum conditions, Ca-ISE-based aptasensing platform exhibited good electrode potential response for evaluation of target CEA, and allowed detection of CEA at a concentration as low as 7.3 pg mL −1 . Importantly, Ca-ISE-based aptasensing system is readily extended to detect other disease-related glycoproteins by controlling the corresponding aptamer.
