A two-d.mensional (2d. zirconium-based.metal-organic framework (Zr-MOF) with abund.nt terminal -OH/-OH2 groups on its nod.s, ZrBTB (BTB = 1,3,5-tris(4-carboxyph.nyl)benzene), is utilized.as a platform for d.al post-synthetic mod.fications (PSM) to immobilize both the benzoph.none-based.ph.tosensitizer (benzoph.none-4,4′-d.carboxylate, bzpd.) and.terbium ions onto the 2d.Zr-MOF molecular sheets. Terbium ions are installed.on the 2d.Zr-MOF at various temperatures to ad.ust the load.ng of terbium ions on the 2d.Zr-MOF while preserving the load.ng of the ph.tosensitizer. The crystallinity, morph.logy, porosity, and.load.ngs of both bzpd. ligand. and.terbium ions are characterized.for each material, and.the coord.nating locations of terbium ions in the Zr-MOF structure are investigated. The ph.toluminescence (PL) properties of these materials are then examined. Since the installed.bzpd. ligand.can ind.ce a highly efficient energy transfer to the neighbouring terbium ion upon excitation, the obtained.material after d.al PSM (ZrBTB-bzpd.-Tb-120) can show strong PL emissions of terbium ions upon the excitation of the bzpd. ligand.at 355 nm, with a PL quantum yield.of 5.04%. It is more ad.antageous than the 2d.Zr-MOF solely functionalized.with terbium ions, which can only exhibit similar emissions upon the excitation of the BTB linker at a less friend.y wavelength of 310 nm, with a lower PL quantum yield.of 2.94%. Owing to the high chemical stability as well as good.d.spersity of the luminescent ZrBTB-bzpd.-Tb-120 in water, its performances in selective PL sensing of Fe(iii) ions present in aqueous solutions are investigated. © 2024 The Royal Society of Chemistry.

Quantum d.t color converters (Qd.Cs) currently have the unsolved.problems of ph.tostability and.d.scolorization in appearance after long-term operation in microd.splays. Instead.of polymer-to-carbon conversion and.or impurity precipitation, the macroscopic bright-yellow-to-d.rk-brown d.scolorization is d.termined.by microscopic interfacial chemical reactions of the Qd.ligand.polymer system. The ph.nomenon has been confirmed.to be related.to multiple factors, includ.ng chemical transformation of the Qd.shell and.partial d.grad.tion of the polymer, resulting in increased.optical reflectance and.red.ced.ph.toluminescence (PL) intensity in Qd.Cs. Our find.ng suggests that the ph.toexcitation of Qd. in the polymer matrix should.lead.to d.tached.surface ligand. along with ph.tocatalytic reactions, oxid.zing the Qd.shell together with d.grad.ng the polymer chains. © 2024 The Authors.

In resource allocation d.cisions in business, fully und.rstand.ng customers’ need. and.preferences helps to maximise benefits. As a result, in the mod.rn business environment, the d.sign of customized.recommend.tion systems has gained.a lot of attention. To this end. the stud. d.signs a recommend.tion algorithm for resource allocation d.cision based.on improved.two-part graph.network structure. In this algorithm, an improved.K-means clustering algorithm is introd.ced.to d.eply mine potential information. The calculation of similarity between users is also optimised.to assist the target user to find.the real neighbouring users. The find.ngs d.monstrate that, in comparison to the other algorithms, the resource allocation recommend.tion algorithm based.on improved.bipartite graph.suggested.in the stud. has a greater hit rate. The hit rate of the suggested.algorithm can reach 32.5% when the recommend.tion list length is 10, which is a 21.5% improvement over the collaborative filtering algorithm. The suggested.algorithm’s popularity is only 39.1, which is 69.3 less than the collaborative filtering algorithm when the suggestion list length is 10. Furthermore, the suggested.algorithm for resource allocation d.cision-making created.by the research has a greater recommend.tion accuracy, more personalization, and.d.versity, as seen by the proposed.algorithm’s mean Hamming d.stance of 0.976. Through an improved.bipartite graph.network, the algorithm can fully analyze the historical preference information of users, effectively capture the complex relationship between users and.prod.cts, generate personalized.recommend.tion lists, and.improve user satisfaction and.purchase conversion rates. It provid.s an effective recommend.tion role for resource allocation d.cisions in mod.rn business and.helps to create greater economic benefits. © 2025 Institute of Electronics Engineers of Korea.

In this stud., gold.nanocubes (AuNCs) were quickly synthesized.using the seed.med.ated.growth method.and.red.ced.onto the surface of two-d.mensional (2d. d.laminated.nano mica platelets (NMPs), enabling the d.velopment of AuNCs/NMPs nanohybrid. with a 3d.lightning-rod.effect. First, the growth-solution amount can be changed.to easily ad.ust the AuNCs average-particle size within a range of 30-70 nm. The use of the cationic surfactant cetyltrimethylammonium chlorid. as a protective agent allowed.the surface of AuNCs and.nanohybrid. to be positively charged. Positively charged.nanohybrid.surfaces presented.a good.ad.orption effect for d.tecting molecules with negative charges on the surface. Ad.itionally, the NMP surfaces were rich in ionic charges and.provid.d.a large specific surface area for stabilizing the growth of AuNCs. d.laminated.AuNCs/NMPs nanohybrid. can generate a 3d.hotspot effect through self-assembly to enhance the Raman signal. Surface-enhanced.Raman scattering (SERS) is highly sensitive in d.tecting ad.nine biomolecules. Its limit of d.tection (LOd. and.Raman enhancement factor reached.10−9 M and.3.6 × 108, respectively. Excellent reprod.cibility was obtained.owing to the relatively regular arrangement of AuNC particles, and.the relative stand.rd.d.viation (RSd. was 10.7%. Finally, the surface of NMPs was mod.fied.by ad.ing the hyd.oph.lic poly(oxyethylene)-d.amine (POE2000) and.amph.ph.lic PIB-POE-PIB copolymer at d.fferent weight ratios. The ad.ustment of the surface hyd.oph.licity and.hyd.oph.bicity of AuNCs/NMPs nanohybrid. led.to better ad.orption and.selectivity for bacteria. AuNCs/POE/NMPs and.AuNCs/PIB-POE-PIB/NMPs were further applied.to the SERS d.tection of hyd.oph.lic Staph.lococcus aureus and.hyd.oph.bic Escherichia coli, respectively. The SERS-d.tection results suggest that the LOd.of hyd.oph.lic Staph.lococcus aureus and.hyd.oph.bic Escherichia coli reached.92 CFU mL−1 and.1.6 × 102 CFU mL−1, respectively.

The evaluation of enterprise financial performance is of great significance to investors, cred.tors and.managers. Through the performance evaluation, we can jud.e the comprehensive strength of the enterprise and.then take correspond.ng countermeasures. The stud. mainly quantifies the three financial performance factors of profitability, operating ability and.solvency in segments. At the same time, variables are constructed.for the statement subjects other than the performance factors. In ad.ition, an iterative binary tree three-generation algorithm mod.l based.on d.cision coord.nation d.gree is introd.ced.to classify and.measure the financial performance of enterprises. The stud. used.528 financial statements from a manufacturing ind.stry and.employed.a mean imputation strategy and.Z-score stand.rd.zation method.for preprocessing. Ultimately, 19 variables were selected.for financial performance evaluation. Using the mod.l's construction time, classification accuracy, and.area und.r the curve as evaluation ind.cators, verify the performance ad.antages of the proposed.mod.l in financial performance evaluation. The results show that when the sample size is 300, the construction time of the improved.mod.l is only 120ms, and.out of 50 financial statements, only 7 financial statements with "poor" profitability are misclassified.as "excellent". The average classification accuracy of the improved.mod.l is 87.57% and.the average area und.r the curve is 0.8369. In the solvency test, the average classification accuracy of the improved.mod.l in the solvency ind.cator is 84.21%. In the test of operating capacity ind.cators, the mean value of classification accuracy of the improved.mod.l proposed.by the Institute in operating capacity ind.cators is as high as 85.16%. The results show that the classification mod.l proposed.by the Institute has the least construction time and.the highest classification accuracy.

In this article, we harnessed.biomed.cal applications in laser-assisted.etching long-period.fiber gratings (LLPFGs) sensors, subsequently d.ploying them within the realm of biomed.cal applications. The primary aim of this stud. was to d.vise a sensitive method.for the d.tection of antigen-antibod.es associated.with rheumatoid.arthritis (RA) using LLPFGs. Sensing the antigen bind.ng took place on the surface of the optical fiber through a self-assembling process. Given the inherent limitations of conventional rheumatoid.factor (RF) testing in terms of specificity, we introd.ced.an innovative serum-based.approach geared.toward.the id.ntification of anti-cyclic citrullinated.peptid. (Anti-CCP) antibod.es. This method.exhibited.an impressive d.agnostic accuracy rate of approximately 80% for RA cases, coupled.with an exceptional specificity level of 98% for ind.vid.als without RA. The incorporation of LLPFGs in the d.tection of RA antigen-antibod.es presents a highly promising avenue for enhancing the precision and.reliability of RA d.agnosis. Furthermore, this research aligns closely with the United.Nations Sustainable d.velopment Goal (Sd.)3, which strives to promote well-being across all age groups and.ad.ance sustainable d.velopment by ad.ressing health-related.challenges, includ.ng the accurate d.agnosis of d.seases like RA. © 2023 IEEE.

While temozolomid. (TMZ) has been a cornerstone in the treatment of newly d.agnosed.glioblastoma (GBM), a significant challenge has been the emergence of resistance to TMZ, which compromises its clinical benefits. Ad.itionally, the nonspecificity of TMZ can lead.to d.trimental sid. effects. Although TMZ is capable of penetrating the blood.brain barrier (BBB), our research ad.resses the need.for targeted.therapy to circumvent resistance mechanisms and.red.ce off-target effects. This stud. introd.ces the use of PEGylated.mesoporous silica nanoparticles (MSN) with octyl group mod.fications (C8-MSN) as a nanocarrier system for the d.livery of d.cetaxel (d.X), provid.ng a novel approach for treating TMZ-resistant GBM. Our find.ngs reveal that C8-MSN is biocompatible in vitro, and.d.X@C8-MSN shows no hemolytic activity at therapeutic concentrations, maintaining efficacy against GBM cells. Crucially, in vivo imaging d.monstrates preferential accumulation of C8-MSN within the tumor region, suggesting enhanced.permeability across the blood.brain tumor barrier (BBTB). When ad.inistered.to orthotopic glioma mouse mod.ls, d.X@C8-MSN notably prolongs survival by over 50%, significantly red.ces tumor volume, and.d.creases sid. effects compared.to free d.X, ind.cating a targeted.and.effective approach to treatment. The apoptotic pathways activated.by d.X@C8-MSN, evid.nced.by the increased.levels of cleaved.caspase-3 and.PARP, point to a potent therapeutic mechanism. Collectively, the results ad.ocate d.X@C8-MSN as a promising cand.d.te for targeted.therapy in TMZ-resistant GBM, optimizing d.ug d.livery and.bioavailability to overcome current therapeutic limitations. © 2024 The Authors.

The aim of this stud. is to establish the key factors for the d.velopment of cooking classes in Taiwan’s rural bed.and.breakfasts (B&Bs) to ad.ress the gaps in Taiwan’s research on this topic and.contribute new knowled.e to the d.velopment of Taiwan’s B&B ind.stry. This stud. was cond.cted.in two stages. In the first stage, the fuzzy d.lph. method.(Fd.) was used.to collect expert opinions and.construct ind.cators;in the second.stage, the analytic hierarchy process (AHP) was used.to analyse the importance of ind.cators. The research results ind.cated.that the most important factor for the d.velopment of cooking classes at rural B&Bs is “homestay management”, of which environmental hygiene and.cleanliness are the most important ind.cators. This stud. fills the research gap related.to gourmet and.cooking tourism within the B&B ind.stry, and.the most notable contribution of this stud. is the id.ntification of the key factors for the d.velopment of cooking classes at rural B&Bs. In ad.ition, this stud. serves as a reference for the d.velopment of new business types in the B&B ind.stry in Taiwan. The criteria of this stud. were evaluated.by experts in various field.. Because the d.velopment of food.tourism and.cooking classes in Taiwan is still a novel topic, there may be many aspects that have not yet been explored. which is the most notable limitation of this stud.. © The Author(s), und.r exclusive licence to Springer Nature B.V. 2024.

In recent stud.es, iron-containing Fenton nanocatalysts have d.monstrated.significant promise for clinical use d.e to their effective antitumor activity and.low cytotoxicity. A new approach was reported.in this work utilizing cation exchange synthesis to fabricate FeMnOx nanoparticles (NPs) that boost Fenton reactions and.responses to the tumor microenvironment (TME) for chemod.namic therapy (Cd.) and.chemotherapy (CT). Within the TME, the red.x metal pair of Fe2+/Mn2+ helps break d.wn end.genous hyd.ogen peroxid. (H2O2) into very harmful hyd.oxyl rad.cals (•OH) while simultaneously d.activating glutathione (GSH) to boost Cd. performance. To further enhance the therapeutic potential, FeMnOx NPs were encapsulated.with thioketal-linked.camptothecin (CPT-TK-COOH), a reactive oxygen species (ROS)-responsive prod.ug, achieving a high CPT-load.ng capacity of up to 51.1%. Upon ROS generation through the Fenton reaction, the prod.ug TK linkage was d.srupted. releasing 80% of the CPT payload.within 48 h. Notably, FeMnOx@CPT exhibited.excellent d.al-mod.l imaging capabilities, enabling magnetic resonance and.fluorescence imaging for image-guid.d.therapy. In vitro stud.es showed.the cytocompatibility of FeMnOx NPs using Md.-Mb-231 and.4T1 cells, but in the presence of H2O2, they ind.ced.significant cytotoxicity, resulting in 80% cell d.ath through Cd. and.CT effects. Upon intravenous ad.inistration, FeMnOx@CPT d.splayed.remarkable tumor accumulation, which enhanced.tumor suppression in xenografts through improved.Cd. and.CT effects. Moreover, no significant ad.erse effects were observed.in the FeMnOx NP-treated.animals. In the current stud., the FeMnOx@CPT anticancer platform, with its boosted.•OH-prod.cing capability and.ROS-cleavable d.ug release, has been valid.ted.utilizing in vitro and.animal stud.es, suggesting its capacity as a viable strategy for clinical trials. © 2023 American Chemical Society.
