Celecoxib is a nonsteroidal anti-inflammatory drug used to reduce pain and inflammation caused by conditions such as arthritis, ankylosing spondylitis and menstrual pain. To enhance its effectiveness and reduce the likelihood of side effects, it is essential to create drug delivery systems designed for better controlled release. We herein report the synthesis of [Cu₃(btc)₂] using the solvent-based method and characterized using BET, CHN, FT-IR, PXRD, SEM, TEM & TGA. [Cu₃(btc)₂] commonly referred to as HKUST-1/MOF-199 is among the first stable MOFs identified, boasting an exceptionally high surface area. After characterization, the synthesized [Cu₃(btc)₂] was modified by introducing ED into the framworks to form [Cu₃(btc)₂]-ED which was characterized by BET, EDX, FT-IR, PXRD, SEM, TEM and TGA. The two porous Cu-MOFs prepared in this study were used for storage and stable delivery of Celecoxib for the first time. The storage capacities of [Cu₃(btc)₂] and [Cu₃(btc)₂]-ED were 680.15 mg/g and 504.22 mg/g respectively, which also demonstrates effective and controlled drug delivery properties. The results indicate that the storage capacity of [Cu₃(btc)₂] is higher than that of [Cu₃(btc)₂]-ED, which could be attributed to its high pore volume and large surface area. The pharmacokinetics of the two Cu-MOFs show that Celecoxib was fully delivered after 48 h. Molecular docking shows that celecoxib binds strongly to [Cu₃(btc)₂] via π–π stacking and Cu-centered interactions, while binding in [Cu₃(btc)₂]–ED is dominated by hydrogen bonding and aromatic contacts. The findings from this research present a novel opportunity for [Cu₃(btc)₂] and [Cu₃(btc)₂]-ED to serve as a potential platform for Celecoxib storage and stable delivery.

塞来昔布是一种非甾体抗炎药，用于减轻关节炎、强直性脊柱炎和经期疼痛等疾病引起的疼痛和炎症。为了提高其有效性并减少副作用的可能性，必须创建设计为更好地控制释放的药物传递系统。本文报道了以溶剂为基础合成[Cu3(btc)2]的方法，并利用BET、CHN、FT-IR、PXRD、SEM、TEM和TGA对其进行了表征。[Cu3(btc)2]通常被称为HKUST-1/MOF-199，是首批确定的稳定mof之一，具有极高的表面积。表征完成后，将合成的[Cu3(btc)2]通过在骨架中引入ED进行修饰，形成[Cu3(btc)2]-ED，并用BET、EDX、FT-IR、PXRD、SEM、TEM和TGA对其进行了表征。本研究首次将制备的两种多孔Cu-MOFs用于塞来昔布的储存和稳定递送。[Cu3(btc)2]和[Cu3(btc)2]-ED的储药量分别为680.15 mg/g和504.22 mg/g，具有有效和可控的给药性能。结果表明，[Cu3(btc)2]的存储容量高于[Cu3(btc)2]-ED，这可能与[Cu3(btc)2]-ED的高孔体积和大表面积有关。两种cu - mof的药代动力学表明，塞来昔布在48 h后被完全递送。分子对接表明，塞来昔布通过π -π堆叠和cu中心相互作用与[Cu3(btc)2]强结合，而在[Cu3(btc)2] -ED上的结合主要是氢键和芳香接触。这项研究的发现为[Cu3(btc)2]和[Cu3(btc)2]-ED提供了一个新的机会，可以作为塞来昔布储存和稳定递送的潜在平台。

The application of cadmium sulfide (CdS) photocatalyst for practical wastewater treatment in the photocatalysis field is strictly limited by the main disadvantages of ultrafast charge-carrier recombination rate and extensive photo-corrosion under solar exposure, making the CdS less than ideal for large-scale lifetime potentials and translatability. Although recent literature attempts to remedy such concerns with complicated heterojunction construction or elemental doping, such methods increase synthetic intricacies making real-world implementation impossible. On the other hand, limited focus has been placed on the precursor sulfur source to create the desired defects, crystallite formations, and charge transfer mechanisms despite its fundamental research toward tuning photocatalyst performance. Thus, in the present paper, we explore the precursory sulfur source during the synthetic step to demonstrate a structure-function relationship across two distinct precursors of surfer (S) namely sodium sulfide (CdS-SS) and thiourea (CdS-TU). The finding shows that the CdS-TU photocatalyst boasts superior long-range crystallinity while the CdS-SS photocatalyst provides a mesoporous structure abundant in advantageous sulfur-vacancy defects. Interestingly, the CdS-SS exhibits greatly quenched photoluminescence emission which corelates well with the exceptional solar-driven photocatalytic performance of 99% degradation of azo dyes, Reactive Red 141 (RR141) dye and Congo Red (CR) dye, together with 90% detoxification of ofloxacin (OFL) antibiotic. The prepared CdS-SS photocatalyst provides the enhanced first-order rate constant, about three times higher than that detected from the CdS-TU photocatalyst. Trapping experiment demonstrates that photogenerated holes (h⁺) are the dominant reactive species involved in removal of the pollutant. The prepared CdS-SS retains its promising photoactivity with the original morphology after five cycles of use. This paper demonstrates the precursor-based defect engineering strategy to fabricate a promising solar-driven CdS photocatalyst for environmental application.

硫化镉（cd）光催化剂在实际废水处理中的应用受到了光催化领域的严格限制，其主要缺点是电荷-载流子复合速率超快和在太阳照射下广泛的光腐蚀，使得CdS不太理想的大规模寿命电位和可译性。尽管最近的文献试图用复杂的异质结结构或元素掺杂来解决这些问题，但这些方法增加了合成的复杂性，使现实世界的实现变得不可能。另一方面，尽管前驱体硫源在调整光催化剂性能方面进行了基础研究，但人们对其产生所需缺陷、晶体形成和电荷转移机制的关注有限。因此，在本文中，我们在合成步骤中探索了前体硫源，以证明两种不同的冲浪剂(S)前体即硫化钠（CdS-SS）和硫脲（CdS-TU）之间的结构-功能关系。结果表明，CdS-TU光催化剂具有优异的远端结晶度，而CdS-SS光催化剂具有丰富的中孔结构，具有有利的硫空位缺陷。有趣的是，CdS-SS表现出极大的猝灭光致发光，这与优异的太阳能驱动光催化性能密切相关，该性能可降解偶氮染料、活性红141 （RR141）染料和果果红（CR）染料99%，并可解毒氧氟沙星（OFL）抗生素90%。制备的CdS-SS光催化剂提供了提高的一级速率常数，比CdS-TU光催化剂高约3倍。捕集实验表明，光生空穴（h+）是参与污染物去除的主要反应物质。经5次循环使用后，所制备的CdS-SS仍具有良好的光活性。本文展示了基于前驱体的缺陷工程策略，以制造一种有前途的环境应用太阳能驱动CdS光催化剂。

The sulfated carrageenan/Fe₃O₄/(CuO:NiO:ZnO) nanocomposite (Scar/Fe₃O₄/CuO:NiO:ZnO)) was prepared through a multi-step process. Fe₃O₄ nanoparticles were first synthesized via co-precipitation. Then, the ternary metal oxide nanoparticles (CuO:NiO:ZnO) were hydrothermally prepared and calcined. These metal oxides were combined with Fe₃O₄ to form a well-dispersed Fe₃O₄/(CuO:NiO:ZnO) nanocomposite. Sulfated carrageenan (SCar) was subsequently prepared, and the Fe₃O₄/(CuO:NiO:ZnO) nanoparticles were incorporated into its matrix, resulting in a uniform and stable final nanocomposite. Comprehensive characterization using FT-IR, XRD, FE-SEM, EDS, VSM, and BET confirmed successful incorporation of the nanoparticles, uniform morphology, superparamagnetic behavior, and a large specific surface area. The prepared nanocomposite acted as an efficient and recyclable heterogeneous catalyst for the one-pot synthesis of benzylpyrazolyl naphthoquinone derivatives under mild conditions. The reactions proceeded with excellent yields (85–95%) and short reaction times (45–100 min). The synthesized derivatives exhibited notable biological activities, demonstrating significant antioxidant properties in the DPPH assay with inhibition values ranging from 36% to 91%. Moreover, the synthesized compounds exhibited antibacterial effects against E. coli, S. aureus, B. subtilis, and S. enteritidis, with inhibition zones measured between 8 and 11 mm. Excellent recyclability was observed for the nanocomposite catalyst, as it preserved approximately 88% of its efficiency after five reuse cycles, indicating its promise for green and long-term catalytic applications.

采用多步工艺制备了硫酸化卡拉胶/Fe₃O₄/(CuO:NiO:ZnO)纳米复合材料（Scar/Fe₃O₄/CuO:NiO:ZnO）。采用共沉淀法首次合成了Fe₃O₄纳米颗粒。然后，水热法制备了CuO:NiO:ZnO三元金属氧化物纳米颗粒，并进行了煅烧。这些金属氧化物与Fe₃O₄结合形成分散良好的Fe₃O₄/(CuO:NiO:ZnO)纳米复合材料。随后制备了硫酸化卡拉胶（SCar），并将Fe₃O₄/(CuO:NiO:ZnO)纳米颗粒掺入其基体中，得到了均匀稳定的纳米复合材料。利用FT-IR、XRD、FE-SEM、EDS、VSM和BET进行综合表征，证实了纳米颗粒的成功结合、均匀的形貌、超顺磁行为和大的比表面积。所制备的纳米复合材料可作为一种高效、可回收的多相催化剂，在温和条件下用于一锅法合成苄基吡唑基萘醌衍生物。反应收率高（85-95%），反应时间短（45-100 min）。合成的衍生物具有显著的生物活性，在DPPH实验中显示出显著的抗氧化性能，抑制值为36% ~ 91%。此外，合成的化合物对大肠杆菌、金黄色葡萄球菌、枯草芽孢杆菌和肠炎链球菌具有抗菌作用，抑菌区在8 ~ 11 mm之间。纳米复合催化剂具有优异的可回收性，在5次循环使用后仍能保持约88%的效率，这表明其具有绿色和长期的催化应用前景。

Circularly polarized radioluminescence (CPRL) exhibits promising and pivotal applications in fields such as CPRL-OLEDs, 3D displays, information encryption and storage, and high-resolution X-ray imaging. Herein, a pair of chiral complexes, [(R, R)/ (S, S)-[(L)₂TbZn₂(H₂O)₄] (ClO₄)₃ (R/S-Zn-Tb) were synthesized. The chiral complexes have strong X-ray scintillation performance with the X-ray detection limit of 53.8 nGy·s⁻¹, 55.3 nGy·s⁻¹, light yield of 1940 pH·MeV⁻¹, 1917 pH·MeV⁻¹ based on LuAG:Ce, and quantum efficiency of 33.37%, 32.99% for R-Zn-Tb and S-Zn-Tb, respectively. Spectra experiments show that they exhibit strong CPL with asymmetry factors of 5.2 × 10⁻² for R/S-Zn-Tb. Chiral flexible transparent films were prepared using the chiral complexes, and the dissymmetry factor of CPRL film based on R/S-Zn-Tb is 1.1 × 10⁻². X-ray imaging was performed using the R/S-Zn-Tb@PMMA films, and the high-resolution X-ray imaging was obtained with resolution of 20.893 lp/mm. The results firstly demonstrate that lanthanide chiral complexes can constitute a promising chiral scintillator material.

The commercialization of lithium–sulfur (LiS) batteries is limited by the dissolution and migration of lithium polysulfides, which cause rapid capacity decay and poor cycling stability. Here, we introduce laser-induced graphene (LIG) as a multifunctional separator coating to mitigate these issues. LIG, produced via direct laser scribing of polyimide, forms a three-dimensional, porous graphenic network with high conductivity and tunable heteroatom functionality. Its hierarchical structure of few-layer graphene nanosheets provides abundant sites for physical confinement of polysulfides while enabling rapid electron transport. Electrochemical tests show that LIG-coated separators significantly enhance sulfur utilization, suppress the shuttle effect, and deliver stable reversible capacities of ∼950 mAh g⁻¹ after 400 cycles under high sulfur loading, with excellent rate performance. Density-of-states analysis confirms that defect-rich regions in LIG strengthen sulfur binding and facilitate charge transfer. In-situ SEM and EDS mapping demonstrate the structural resilience of LIG, maintaining morphological integrity after prolonged cycling. These findings establish LIG-coated separators as a scalable and effective strategy for high-performance, durable LiS batteries.

锂硫电池的商业化受到多硫化物锂的溶解和迁移的限制，导致容量衰减快，循环稳定性差。在这里，我们引入激光诱导石墨烯（LIG）作为多功能隔膜涂层来缓解这些问题。LIG通过直接激光刻划聚酰亚胺制备，形成具有高导电性和可调谐杂原子功能的三维多孔石墨网络。其多层石墨烯纳米片的分层结构为多硫化物的物理限制提供了丰富的场所，同时实现了快速的电子传递。电化学测试表明，在高硫负载下，锂离子包覆的分离器显著提高了硫的利用率，抑制了穿梭效应，并在400次循环后提供了稳定的~ 950 mAh g−1的可逆容量，具有优异的倍率性能。态密度分析证实，LIG中富含缺陷的区域加强了硫结合，促进了电荷转移。原位SEM和EDS图谱显示了LIG的结构弹性，在长时间循环后保持形态完整性。这些发现确立了锂离子涂层隔膜作为高性能、耐用锂离子电池的可扩展和有效策略。

Transition metal oxide (TMO) nanomaterials have emerged as versatile antimicrobial platforms at a time when antimicrobial resistance (AMR) is eroding the utility of conventional drugs. Their rich defect chemistry, redox activity, and tunable band structures enable multiple microbicidal pathways, including reactive oxygen species generation, membrane disruption, metal-ion release, and biomolecular damage. A large body of work now reports antimicrobial TMOs. Yet, existing reviews are often limited to individual oxides, a single synthesis route, or specific applications, and rarely connect synthesis, structure, and mechanism across biomedical and technological contexts. This review provides an integrated, state-of-the-art overview of antimicrobial TMOs, with emphasis on widely studied systems such as ZnO, CuO, TiO₂, and Fe₃O₄. We critically summarize physical, chemical, and green/bio-inspired synthesis routes and their influence on size, morphology, surface chemistry, and defect structures, as revealed by XRD, electron microscopy, vibrational, and optical spectroscopies. Antimicrobial mechanisms are discussed alongside standard assays, including planktonic and biofilm models. Finally, we highlight applications in medicine, water treatment, food packaging, agriculture, personal care products, and textiles, and outline key challenges in toxicity, scalability, and standardization. By linking synthesis–structure–mechanism–application, this review identifies design principles for the next generation of safe, effective TMO-based antimicrobials with a focus on translational implementation.

在抗菌素耐药性（AMR）正在侵蚀传统药物的效用之际，过渡金属氧化物（TMO）纳米材料已成为多功能抗菌素平台。它们丰富的缺陷化学、氧化还原活性和可调谐的能带结构使多种杀微生物途径成为可能，包括活性氧生成、膜破坏、金属离子释放和生物分子损伤。现在大量的工作报告了抗菌TMOs。然而，现有的综述往往局限于单个氧化物、单一合成路线或特定应用，很少将生物医学和技术背景下的合成、结构和机制联系起来。这篇综述提供了一个综合的，最先进的抗菌TMOs的概述，重点是广泛研究的系统，如ZnO， CuO, TiO₂，和Fe₃O₄。我们批判性地总结了物理，化学和绿色/生物启发合成路线及其对尺寸，形貌，表面化学和缺陷结构的影响，通过XRD，电子显微镜，振动和光谱学揭示。抗菌机制与标准分析一起讨论，包括浮游生物和生物膜模型。最后，我们重点介绍了在医药、水处理、食品包装、农业、个人护理产品和纺织品方面的应用，并概述了在毒性、可扩展性和标准化方面的主要挑战。通过将合成-结构-机制-应用联系起来，本综述确定了下一代安全有效的基于tmo的抗菌素的设计原则，重点是转化实施。

The nanocomposites TiO₂/x SrFe₁₂O₁₉ (x = 1%, 3%, 5% and 7%) were prepared by the sono-mechanical method, while SrFe₁₂O₁₉ was synthesized by the co-precipitation method. The X-ray diffraction (XRD) analysis of TiO₂/SrFe₁₂O₁₉ at varying concentrations (1–7 wt%) reveals dominant TiO₂ peaks without distinct SrFe₁₂O₁₉ peaks. The optical properties of TiO₂/SrFe₁₂O₁₉ (0.1–0.7 wt%) were analyzed using diffuse reflectance spectroscopy (DRS) and absorbance measurements over 200–2500 nm. Increased SrFe₁₂O₁₉ concentration reduced reflectance and enhanced absorbance in the visible-NIR range, suggesting improved light-trapping effects. The magnetic properties of nanocomposites TiO₂/x SrFe₁₂O₁₉ were investigated using a vibrating sample magnetometer. The magnetic parameters, such as saturation magnetization and coercivity, were enhanced with SFO content make them suitable for spintronic and memory applications. The gamma-ray shielding properties were evaluated by calculating key parameters, including the mean atomic number, mass, electron density, and effective atomic number (Z_eff). The results demonstrate that incorporating SrFe₁₂ O₁₉ enhances shielding performance, as evidenced by the increase in Z_eff. For fast neutron attenuation, the removal cross-section (Σ_R) calculations indicate that replacing 7% of TiO₂ with SrFe₁₂ O₁₉ leads to only a negligible reduction (0.44%) in shielding efficiency. These findings suggest that substituting TiO₂ with SrFe₁₂ O₁₉ optimizes radiation shielding by effectively balancing gamma-ray and neutron attenuation with minimal compromise in performance.

采用超声机械法制备了TiO₂/x SrFe₁₂O₁₉₉（x = 1%、3%、5%和7%）纳米复合材料，采用共沉淀法合成了SrFe₁₂O₁₉₉。不同浓度（1-7 wt%）的TiO₂/SrFe₁₂O₁₉的x射线衍射（XRD）分析显示，TiO₂的主要峰没有明显的SrFe₁₂O₁₉的峰。利用漫反射光谱（DRS）和200-2500 nm的吸光度测量分析了TiO₂/SrFe₁₂O₁₉的光学性质（0.1-0.7 wt%）。SrFe₁₂O₁₉浓度的增加降低了可见光至近红外波段的反射率，增强了吸光度，表明捕光效果得到了改善。用振动样品磁强计研究了纳米复合材料TiO₂/x SrFe₁₂O₁₉的磁性能。饱和磁化强度和矫顽力等磁性参数随SFO含量的增加而增强，使其适合自旋电子和存储应用。通过计算包括平均原子序数、质量、电子密度和有效原子序数（Zeff）在内的关键参数来评价其屏蔽γ射线的性能。结果表明，srfe12o19的加入提高了材料的屏蔽性能，Zeff增大了。对于快中子衰减，去除截面（ΣR）计算表明，用SrFe12 O19代替7%的TiO2只导致屏蔽效率的可忽略不计的降低（0.44%）。这些发现表明，用SrFe12 O19取代TiO2可以有效地平衡伽玛射线和中子衰减，从而优化辐射屏蔽性能。

The development of advanced drug contaminant adsorbents requires innovative material design and sustainable synthesis strategies. Herein, we report a room-temperature in situ growth method to construct NH₂-MIL-101(Fe)@COF core-shell hybrid materials, overcoming the limitations of conventional high-energy synthesis while achieving exceptional adsorption performance for diclofenac sodium (DCF). The precisely engineered interface between NH₂-MIL-101(Fe) and the COF layer creates synergistic adsorption sites, combining FeO chelation, electrostatic attraction, and π–π stacking interactions, as revealed by in situ FTIR and XPS studies. The hierarchical pore structure (micropores: 1.97 nm; mesopores: 7.44 nm) enables rapid diffusion kinetics (The adsorption equilibrium was reached within 45 min) and delivers an adsorption capacity of 399.77 mg·g⁻¹, surpassing most reported MOF@COF-based adsorbents. Remarkably, the material retains an adsorption capacity of 216.6 mg·g⁻¹ after five regeneration cycles and demonstrates strong resistance to interference from coexisting ions, highlighting its potential for real-world aqueous applications. This study presents a feasible strategy for the in situ room-temperature synthesis of MOF@COF composites, offering a mild route to fabricate COF-based hybrids with NH₂-MIL-101(Fe).

A series of new lanthanide complexes with electron-donating (triphenylamine-, phenylcarbazole-) and electron-withdrawing (benzoxazole-, methyloxodiazole-, and phenyloxodiazole-) substituted Schiff bases ((E)-N-(2-((2-aryloylhydrazono)methyl)phenyl)-4-methylbenzenesulfonamide), designed to enhance charge carrier mobility, have been synthesized and fully characterized as well as the 2 structures of the compounds were established. Heteroleptic complexes with ligands of both classes were obtained during the mixed-ligand method synthesis. Photoluminescence quantum yield of heteroleptic species in contrast to luminescence lifetime was found to be higher than homoleptic ones – up to 1.65%. An 16% improvement in external current efficiency (ECE) in the same OLED heterostructure was shown (ECE up to 140 μW/W) in comparison with homoleptic ones (ECE up to 120 μW/W). This proves the correctness of the approach to improvement of the electroluminescence of the OLED based on the metal complexes.
