Stability of perovskite is the main limitation of the commercialization of perovskite solar cells . Recent studies have shown that FA-Cs perovskites are expected to achieve ideal crystal structures with outstanding stability when FA content is 30 %. And its bandgap can be adjusted to 1.8 eV, making it suitable for a top battery in the tandem cell. However, when the content of Cs ions in the component exceeds 30 %, phase separation occurs. In this study, a Cs-rich Cs 0.7 FA 0.3 PbI 2 Br perovskite film was synthesized by using a 2D to 3D phase transition method. Through the high orientation of the 2D CsPbI 3 -FAI alloy-like phase and the anisotropic volatilization of FA, a well-oriented α-Cs 0.7 FA 0.3 PbI 2 Br perovskite phase is obtained. The α-Cs 0.7 FA 0.3 PbI 2 Br shows excellent thermal and UV stability and improved humidity stability. Meanwhile, the fabricated Cs 0.7 FA 0.3 PbI 2 Br perovskite solar cell achieved a competitive power conversion efficiency of 14.87 % successfully breaking the world record for this perovskite system. This further advances the research progress of Cs-rich perovskites in highly efficient and stable solar cells.

Innovation of 137 Cs + and 90 Sr 2+ ion exchangers is achieved through heteroatom-bridged integration of polyoxovanadate clusters, whose soft Lewis basic nature and large size promote the selective capture of cesium/strontium radionuclides. The radiolytically stable Na 6 P 4 V 10 O 34 ·19H 2 O ( VPO-1 ) features an interlinkage of {NaV 10 O 26 } clusters and phosphorus bridges, forming nanoscale voids with hydration-lubricated sodium ions. This structure endows VPO-1 with remarkable exchange kinetics ( k 2 Cs = 3.774 g mg −1 min −1 ; k 2 Sr = 1.376 g mg −1 min −1 ), equilibrium removal ( R > 99.3% within 5–10 min), and maximum capacities ( q m Cs = 300.32 mg g −1 ; q m Sr = 113.00 mg g −1 ). The exchange mechanism is illuminated through single-crystal XRD by revealing cluster-vacancy pathways and ionic-radius-dependent adsorption sites. VPO-1 exhibits stability across pH = 3–12, with exceptional K d Cs and K d Sr values above 10 5 mL g −1 , and high selectivity for Cs + and Sr 2+ over various competing ions. These properties enable excellent column filtration performance ( R = 99%–100%) for mixed Cs + and Sr 2+ during a 3000 mL test. Deep cleaning of these ions is also possible via suction filtration using an ultra-thin VPO-1 /PTFE membrane, with high exchange activity ( R = 98.8%–99.9%) retained after simple regeneration with 2 m NaCl, offering significant potential for nuclear wastewater treatment applications.

In the present work, a series of PVA and CS blend membranes were studied. These prepared membranes were evaluated by binary mixture gases of CO 2 /N 2 and CO 2 /CH 4 . The optimum ratio of PVA/CS for CO 2 permeance was achieved at 5:5. It recorded a CO 2 permeability of 20.8 GPU (1 GPU = 1 × 10 -6 ·cm 3 (STP)·cm −2 ·s −1 ·cmHg −1 ) with CO 2 /N 2 selectivity of 89.7, as well as CO 2 permeability of 10.2 GPU and CO 2 /CH 4 selectivity of 56.3. Secondly, two kinds of nanoparticle UiO-66 and UiO-66-NH 2 were used to prepare mixed matrix membranes. The effects of nanofiller content and chemical groups on gas permselectivity were investigated. Results show that the addition of nanoparticles can effectively improve the permselectivity of membrane. The mixed matrix membranes addition with UiO-66-NH 2 achieved the optimum CO 2 performance and these were following the order of PVA(5)/CS(5)-UiO-66-NH 2 > PVA(5)/CS(5)-UiO-66 > PVA(5)/CS(5). For all these membranes, the permeance and selectivity present initial increased and then decreased. Mixed matrix membranes addition UiO-66-NH 2 (containing 3.75 wt%) exhibits a CO 2 permeance of 32.77 GPU and CO 2 /N 2 selectivity of 93.47, as well as CO 2 permeance of 25.57 GPU and CO 2 /CH 4 selectivity of 70.1, which was beyond the 2008 Robeson upper bound.

Unconventional ion exchangers can achieve efficient removal of [UO2]2+, Cs+, and Sr2+ ions from complex aqueous solutions and are of great interest for environmental remediation. We report two new gallium thioantimonates, [Me2NH2]2[Ga2Sb2S7]·H2O (FJSM-GAS-1) and [Et2NH2]2[Ga2Sb2S7]·H2O (FJSM-GAS-2), which present excellent ion exchange properties for [UO2]2+, Cs+, and Sr2+ ions. They exhibit high ion exchange capacities for [UO2]2+, Cs+, and Sr2+ ions (qmU = 196 mg/g, qmCs = 164 mg/g, and qmSr = 80 mg/g for FJSM-GAS-1, qmU = 144 mg/g for FJSM-GAS-2) and short equilibrium times for [UO2]2+ ion exchange (5 min for FJSM-GAS-1 and 15 min for FJSM-GAS-2, respectively). Both compounds display active ion exchange with [UO2]2+ in the pH range of 2.9–10.5. Moreover, the sulfide compounds could maintain high distribution coefficients KdU even in the presence of excess Na+, Ca2+, and HCO3–. The distribution coefficient KdU of 6.06 × 106 mL/g exhibited by FJSM-GAS-1 is the highest among the reported U adsorbents. The [UO2]2+-laden products can be recycled by conveniently eluting the uranium with a low-cost method. These advantages combined with facile synthesis, as well as β and γ radiation resistance, make FJSM-GAS-1 and FJSM-GAS-2 promising for selective separations in nuclear waste remediation.

After an osteosarcoma excision, recurrence and bone defects are significant challenges for clinicians. Combination therapy based on a nanoparticle-based drug delivery system shows great promise in osteosarcoma therapy. In this study, we designed a multifunctional chitosan (CS) nanoparticle , which combined photothermal therapy (PTT) with chemotherapy to synergistically enhance osteosarcoma therapy and bone repair . Curcumin (CM) loaded CS nanoparticles were prepared through ionotropic gelation method and were further functionalized with polydopamine (PDA) coating to form CS-CM-PDA nanoparticles (CCPNPs). The CCPNPs displayed pH- and near-infrared (NIR)- responsive CM release behavior. In vitro anti-cancer results indicated that CCPNPs possessed a long-term stable anti-cancer effect compared to pure CM. The presence of the NIR irradiation combined with CCPNPs resulted in a dramatic decrease in MG-63 osteosarcoma cell viability in 10 min compared with the pure CCPNPs at the concentration of 500 μg/mL. Meanwhile, in vitro study demonstrated that CCPNPs induced MG-63 cell apoptosis via downregulating the expression of Bcl-2 and upregulating the expression levels of Bax and Caspase-3. Besides, CCPNPs could positively induce the proliferation of MC3T3-E1 osteoblast cells in vitro . These results suggested that CCPNPs with bifunctional osteosarcoma therapy and bone repair may be an excellent candidate for local cancer therapy and bone regeneration .

Chitosan (CS) and polyvinyl alcohol (PVA) nanofiber membranes were synthesized via electrospinning and used as supporting materials for powdered porous organic polymer (POP). These membranes were then crosslinked with glutaraldehyde, resulting in nanofiber membranes (CS/PVA/POP) as an efficient adsorbent for Hg(II) ions. Characterization using Fourier transform infrared spectroscopy, X-ray diffraction, and scanning electron microscopy showed that the membranes effectively removed up to 92.9% of mercury ions at optimal conditions, with an adsorption capacity of 116.1 mg/g. The adsorption data fit well with the Langmuir isotherm and pseudo-second-order kinetic models. The efficient uptake of mercury ions was attributed to chemisorption involving active groups (C=S, -NH2, -OH), facilitated by mechanisms such as chelation, complexation, or electron exchange. TheCS/PVA/POPnanofiber membranes demonstrated significant advantages in adsorption capacity, economic viability, and recyclability, providing an effective solution to mercury pollution in water.

High incidence and mortality rates of chronic wounds place a heavy burden on global healthcare systems. Achieving phased delivery of antimicrobial and regenerative drugs is crucial for promoting chronic wound healing. Herein, a microneedle (MN) patch with a biphasic release system was developed using a combination of solvent casting and spraying methods. Additionally, a copper/PDMS mold was introduced to address the issue of deformation in the chitosan material during drying on polydimethylsiloxane (PDMS). The MNs have a bilayer structure, with a hyaluronic acid (HA) coating loaded with doxycycline (DOX) for antibacterial action and a chitosan (CS) core loaded with vascular endothelial growth factor (VEGF) for promoting cell migration and proliferation. Notably, in vitro drug release studies showed that the coating drug was released by 98.8% within 10 hours, while the release of the core drug could be sustained for up to 70 hours. In vivo studies showed that chronic wounds on C57 mice treated with CS/HA-bilayer MNs achieved nearly complete healing by day 9. These wounds exhibited reduced inflammatory cell infiltration, increased epithelial tissue regeneration, and enhanced collagen deposition. This work integrates the staged management of bacterial infection and angiogenesis and offers promising prospects for enhancing chronic wound healing.

Sn-containing hollandite has been highlighted by recent machine learning-guided design as a promising host for radioactive cesium (Cs), yet waste form validation remains limited. Here, a Cs-bearing Sn-based hollandite series, (Ba,Cs) 1.66 (Fe,Sn) 8 O 16 , was synthesized in air by solid-state reaction, with hollandite formation at 1125°C followed by pressureless sintering at 1200°C. x-Ray diffraction confirms hollandite as the major phase across the series, with minor Ba-bearing secondary phases only at low Cs contents. Rietveld refinement reveals anisotropic lattice expansion and a tetragonal-to-monoclinic symmetry change at the Cs-rich end member, accompanied by progressive tightening of tunnel descriptors, indicating a Sn-specific Cs accommodation response distinct from many Ti-based hollandites. Chemical durability was evaluated by monolithic leaching in deionized water at 90°C. At Cs loadings up to ∼17 wt%, 7-day Cs release is comparable to representative Ti-based hollandites tested under similar conditions. Sn exhibits ultralow normalized release, while Cs and Ba show higher release without detectable degradation of the hollandite matrix. Extended 28-day interval leaching on Ba 0.8 Cs 0.86 Fe 2.46 Sn 5.54 O 16 (HS2) and Ba 0.4 Cs 1.26 Fe 2.06 Sn 5.94 O 16 (HS3) separates rapid early wash-off from slower, diffusion-controlled release. By 14–28 days, Cs and Ba leaching rates converge to ∼2–4 × 10 −2 g·m −2 ·day −1 , with effective diffusion coefficients of ∼1–2 × 10 −11 cm 2 /s and leaching indices of ∼11. Benchmarking against Ti-based hollandites places the Sn-based series within a competitive loading–durability window under a comparatively mild processing route, supporting Sn-based hollandite as a readily fabricated candidate for high-loading Cs immobilization.

The elevation of creatinine in the blood is a typical indicator of renal dysfunction, and persistent renal insufficiency can eventually develop into kidney failure, requiring patients to rely on dialysis or kidney transplantation to maintain their lives. This study focuses on the preparation and performance evaluation of a molecularly imprinted membrane, PVA@CS-MIPs, designed for selective adsorption of creatinine. The PVA@CS-MIPs membrane was fabricated using PVA/CScomposite base membrane prepared via solution casting, with α-methylacrylic acid (MAA) as the functional monomer, N,N′-methylenebisacrylamide (MBA) as the crosslinker, and cerium ammonium sulfate (ACS) and concentrated sulfuric acid as initiators. The PVA@CS-MIPs membrane was characterized using FT–IR, SEM, and XPS. The adsorption and permeation behaviors of PVA@CS-MIPs were investigated, and the underlying mechanisms were discussed. The results demonstrate that PVA@CS-MIPs exhibit a high adsorption capacity of 322.5 mg/g for creatinine and good adsorption selectivity. Moreover, the membrane exhibits excellent reusability. These findings suggest that the prepared PVA@CS-MIPs possesses specific recognition ability forcreatinine and hold promise for applications in hemodialysis-related fields.

Composite particles of oat protein isolate (OPI) and chitosan (CS) were fabricated under different pH and ratio to investigate their interactions, and then used as stabilizers to prepare emulsions for β-carotene delivery. The heat treatment of OPI yielded OPI′, and the binding of OPI′ to CS was enhanced due to the unfolding of its structure. With increasing OPI′:CS ratio and pH value, the particle size and turbidity initially increased and then decreased, accompanied by a shift in the dominant interaction from electrostatic to hydrophobic forces. The strongest hydrophobic interaction was observed at OPI′:CS = 5:1 and pH 7. The emulsion prepared under these conditions exhibited the smallest droplet size (1.55 μm), excellent storage stability, and a high bioaccessibility of β-carotene (36.78%) during in vitro digestion. Furthermore, the OPI′/CS emulsion markedly enhanced the retention of β-carotene under various storage temperatures and UV irradiation, demonstrating great potential for delivering lipophilic bioactive compounds.

137 Cs has become one of the key challenges in the dry reprocessing of spent fuel due to its poor separability and high radioactivity. The synthesis of Cs 2 SnCl 6 for the removal of CsCl from waste salts and the preparation of Cs 2 SnCl 6 -glass composites was investigated in this study. The optimal conditions for the hydrothermal synthesis of Cs 2 SnCl 6 are a reaction at 150°C for 6 h, and XRD results indicate that the product is a pure cubic phase. CsCl is removed from LiCl-KCl-CsCl waste salts by the synthesis of Cs 2 SnCl 6 . This method enables efficient and selective separation of Cs + from waste salts with a Cs + content of 2.5–10 wt.%, achieving a removal efficiency of over 96%. The glass composites have a maximum embedding rate of 30 wt.%. Cs + and Cl − are uniformly distributed in the glass matrix, and the glass matrix exhibits good compatibility with Cs 2 SnCl 6 . The PCT test showed that the normalized leaching rates of Cs + and Cl − on the 28th day were as low as 1.6×10 − 4 and 3.4×10 − 4 g·m − 2 ·d − 1 , respectively, demonstrating that the Cs 2 SnCl 6 -glass composite exhibits excellent leaching resistance.

Construction strategy for selenide exchanger by integrating T3 supertetrahedral clusters. • Synergistic effects of Se component and microporosity on the adsorption kinetics enhancement. • Efficient removal (up to 99.99%) of Cs + and Sr 2+ by column and ultrathin membrane. • High selectivity for Cs + and Sr 2+ in presence of excess coexisting cations and anions. • Great pH (3–12)/irradiation resistance, high exchange selectivity, and facile elution. Elimination of long half-lived 137 Cs + and 90 Sr 2+ hazards through adsorption technique is critical for environmental protection and human health. However, traditional adsorbents are limited in radioactive wastewater treatment by slow kinetics, weak anti-interference, and poor practical applicability. Herein, an indium selenide adsorbent Na 6 In 10 Se 18 ·11.5H 2 O ( InSe-1Na ), with an anionic framework constructed from corner-sharing T3 supertetrahedral clusters, was synthesized using a “assembly-activation” strategy. The soft basic Se component and the cluster-induced microporosity synergistically endow InSe-1Na with remarkable Cs + /Sr 2+ enrichment capacity. It exhibits ultra-fast adsorption kinetics, removing 97.84% of Cs + within 5 min and 99.84% of Sr 2+ within 20 min. The corresponding second-order rate constants ( k 2 ) are 10.241 and 0.335 g mg −1 min −1 , respectively, rendering it the fastest selenide adsorbent. InSe-1Na shows structural stability over a broad pH range of 3–12, with maximum distribution coefficients ( K d ) of 1.02 × 10 5 mL g −1 for Cs + and 8.29 × 10 5 mL g −1 for Sr 2+ . The maximum adsorption capacities ( q m ) of Cs + and Sr 2+ are 252.10 ± 3.77 and 86.49 ± 3.71 mg g −1 , respectively. It exhibits resistance to coexisting ions, maintaining a removal rate ( R ) ≥ 94.73% in the presence of 10 mmol L −1 Na + . Moreover, the rapid kinetic response facilitates its application in column ( R = 99.65%–99.99%) and membrane ( R = 98.95%–99.98%, 0.40 s contact time) filtrations for mixed Cs + and Sr 2+ flow. Given its straightforward synthesis, β/γ irradiation tolerance, and easy elution, InSe-1Na represents a promising adsorbent for radioactive decontamination. Deep purification of nuclear contaminated water containing radioactive 137 Cs + and 90 Sr 2+ is promisingly achieved by a supertetrahedral-cluster-constructed indium selenide ion exchanger, Na 6 In 10 Se 18 ⸱ 11.5H 2 O ( InSe-1Na ), whose soft Se component and microporosity endow this material with top-ranked adsorption kinetics (even in suction filtration conditions with 0.40 s contact time), high capacities, superior selectivity, good resistance to acid/base/coexisting ions, and remarkable column/membrane performances.
