However, due to cost and environmental considerations, there is an increasing emphasis on utilizing green materials. This shift toward sustainable materials and processing is expected to become essential in materials research. In this work, we report the microstructural evolution of thin films of the Cu–Sb–S (CAS) system. The films were obtained by annealing amorphous Sb2S3 precursor films previously immersed in a copper solution with variable residence time. Our main findings demonstrate that varying the residence time in immersion together with the annealing and crystallization of the precursor films leads to a controlled incorporation/distribution of Cu into the films, which promotes the formation of films with phases spanning from a mixture between Sb2S3 and CuSbS2 to a pure Cu12Sb4S13 phase, which represents a significant variation in optoelectronic properties. The phase transition mechanisms were investigated using first-principles calculations and correlated with the structural, morphological, and optoelectronic characterization. Results indicate that vacancies serve as nucleation sites for copper incorporation. Subsequently, interstitial sites are occupied during the phase transformation from Sb2S3 to CuSbS2, whereas the transition from CuSbS2 to Cu12Sb4S13 proceeds via a substitutional mechanism. This study contributes to understanding the fundamental phenomena underlying our proposed methodology. These results could promote the development of CAS-based semiconductors with predetermined properties by manipulating simple process parameters, such as the residence time in a copper solution.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"146 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142849749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, microdefects in the framework of GO membranes induced by the imperfect stacking of GO nanosheets undermine their size-sieving ability and structural stability in aqueous systems. This study proposes a targeted growth approach by growing zeolitic imidazolate framework-8 (ZIF-8) nanocrystals precisely to patch microdefects as well as to cross-link the porous graphene oxide (PGO) flakes coated on the outer surface of the hollow fiber (HF) alumina substrate (named the hybrid PGO/ZIF-8 membrane). This method simultaneously improves their structural stability and size-sieving performance without compromising their water permeance. Various structural and elemental analyses were used to elucidate the targeted growth of the ZIF-8 crystals. The X-ray photoelectron spectroscopy (XPS) analysis confirmed the targeted coordination interaction of oxygen moieties on the edges of PGO nanosheets with metal ions of ZIF-8 crystals, allowing for the precise growth of the ZIF-8 nanocrystals in the PGO membranes. The XPS depth profile analysis revealed the uniform distribution of the ZIF-8 precursor throughout the PGO/ZIF-8 membrane. The resultant membrane showed a water permeance of 4 L m–2 h–1 bar–1 and maintained a very stable performance under pressure and prolonged cross-flow operation. Notably, the molecular weight cutoff (MWCO) improved considerably from 570 to 320 g/mol without sacrificing any water permeance after the targeted growth of ZIF-8. This research paves the way for the preparation of highly selective and stable PGO-based membranes for applications in industrial wastewater treatment.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"56 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142858225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is proven that the modification of the adsorption material is successful by various characterization methods. In the subsequent pollutant removal study, pH, mass, concentration, contact time, and salt ion interference were investigated. The optimal pH for Cu(II) and sulfide removal was 5 and 11, respectively, and the optimal mass of adsorbent was 1 g/L. It was found that the maximum removal rate of Cu (II) was 231.51 mg/g. The adsorption equilibrium time was less than 40 min. This is due to the good adsorption activity of acyl hydrazide groups on the skeleton for Cu (II) through coordination. The maximum desulfurization amount in 60 min was 370.21 mg/g, which was mainly caused by the oxidation of sulfides by surface oxidizing groups. Isotherm and kinetic studies show that the adsorption processes of Cu (II) and sulfides are consistent with the Langmuir model and pseudo-second-order kinetic model. Thermodynamic parameters show that the removal of Cu (II) and sulfides is a spontaneous endothermic process. The adsorption mechanism is mainly chemical adsorption, supplemented by physical adsorption. After 10 regenerated adsorption/desorption cycles, the removal rates of Cu (II) and sulfides remained above 85%, indicating that polystyrenesulfonate acetylhydrazone (LT-HPA) adsorption materials have good reusability. In addition, the adsorbent has good thermal stability, salt resistance, and environmental friendliness. In summary, the modified formylated polystyrene acetyl hydrazone (LT-HPA) has a good application prospect in the removal of copper(II) and sulfides and provides a fresh way for upgrading polystyrene.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"31 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142849744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although many studies discussing PC formation have focused on inert proteins that may inhibit the function of nanomaterials, some functional plasma proteins with intrinsic targeting capabilities can also be adsorbed to the surface of nanomaterials, with active ligand properties to improve the targeting ability. In this approach, nanomaterials are surface-engineered to promote the adsorption of specific functional plasma proteins that are directly targeted to transport nanomaterials to the target site. In this study, T10 peptide-modified liposomes were employed to construct an in situ transferrin (Tf) PC-mediated liposome carrying a hypoxia-sensitive chemotherapy drug (tirapazamine, TPZ) and a photosensitizer (indocyanine green, IR820). The water-soluble drug TPZ was encapsulated in mesoporous silica nanoparticles (MSNs) and coated with IR820 (IR)-loaded liposome. Lipid-coated MSNs can inhibit aggregation in the body and significantly reduce the rapid release of water-soluble drugs, resulting in improved system stability and sustained release. Upon entering the in vivo circulation, T10 bound specifically to Tf in plasma to form an in situ Tf liposome–PC complex with enhanced targeting efficacy compared to traditional ligand-modified active-targeting strategies. However, large-sized PC particles faced challenges in penetrating deep into tumor tissues. IR could kill tumors through photodynamic therapy (PDT) and elicit complementary antitumor effects with the hypoxia-sensitive drug TPZ. This study demonstrates the novel design of in situ PC-mediated multifunctional liposomes for hypoxia-activated chemotherapy combined with PDT, a promising approach to cancer therapy.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"87 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142849745","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it remains challenging to develop materials with high porosity, high diversity of functional groups within the pores, and guest-adaptive tunability. Furthermore, it is challenging to capture large catalysts such as enzymes within porous materials. Protein-based materials are promising candidates to overcome these limitations, owing to their large pore sizes and potential for stimuli-responsive adaptability. In this work, hydrogel beads were generated from cross-linked lysozyme crystals. These swellable lysozyme cross-linked crystals (SLCCs) expand more than 10 mL per gram of crystal following a simple treatment in ethanol, followed by the addition of water. SLCCs are sensitive to the solution environment and change their extent of swelling from adjusting the concentration and identity of the ions in the solution, or by changing the flexibility of the protein backbone, such as adding dithiothreitol to reduce the protein disulfide bonds. SLCCs can adsorb a wide range of catalysts ranging from transition metal complexes to large biomacromolecules, such as the 160 kDa enzyme glucose oxidase (GOx). Transition metal catalysts and enzymes captured within SLCCs maintained their catalytic activity and exhibited minimal leaching. We performed a cascade reaction by adsorbing GOx and the transition metal catalyst Fe-TAML into SLCCs, resulting in enhanced activity compared to a free-floating reaction. SLCCs offer a promising combination of attributes as scaffolds for multicatalytic reactions, including gram-scale batch preparation, tunable expansion to greater than 20-fold in volume, guest-responsive adaptable behavior, and facile capture of a wide array of small molecule and enzyme-catalysts.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"52 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142858227","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work reveals the effects of filler modification and orientation on thermal duction in the boron nitride (BN)/hydroxyethyl cellulose (HEC) through multiscale simulation approaches. Nonequilibrium molecular dynamics (NEMD) identifies that the thermal conductivity of the BN molecule is not size-dependent and proves that thermal resistance is dramatically reduced after hydroxylation modification (BNOH). Finite element simulation (FEM) reveals that maintaining a proper tilt of BN may improve both the cross-plane and in-plane thermal conductivity of the composite. Experimentally, BNOH/HEC composites with high self-viscosity are prepared via a “moisture-activated” strategy, for which the introduction of BNOH and wet hot pressing contribute to the thermal resistance reduction and filler orientation, respectively. The in-plane thermal conductivity reaches 30.64 W/mK with a cross-plane thermal conductivity of 5.06 W/mK. The films show good adaptability to surface morphology with the thermal resistance decreasing to 1.42 K·cm2/W.

In this study, we reported a novel chiral organic donor–acceptor cocrystal based on asymmetrical components of benzo(b)naphtho(1,2-d)thiophene (BNT) and 9-oxo-9H-indeno(1,2-b)pyrazine-2,3-dicarbonitrile (DCAF) that exhibited red emission using a simple solution approach. During the self-assembly, a kinetically controlled growth of polar solvent or substrate induction led to the chiral packing and helical morphology twisted by the cooperation of electrostatic potential energy and chirality. Intriguingly, a “seeding-control” mechanism was newly developed for the production of c-BNT–DCAF helical crystals with a defined uniform chiral form, which enables chirality transfer and amplification from the microscopic to macroscopic level via supramolecular stacking. By introducing chiral additives or even a small break at the edge, the first nucleus acted as a chiral seeding to guide the donor/acceptor molecule alignment into the same handedness. A remarkably high dissymmetry factor (glum) value of 0.1 was demonstrated on the chiral manipulated ribbons, which is the highest among the reported charge-transfer complexes.

In this regard, composite scaffolds offer a strategy to integrate the desired functionalities. These scaffolds are expected to provide sufficient cellular activities while maintaining the required strength necessary for the bone repair for which they are intended. Hence, attempts to obtain efficient composites are growing. However, in most cases, the conventional production methods of scaffolds are energy-intensive and leave an impact on the environment. This work aims to develop a biocomposite scaffold integrating bacterial cellulose (BC), hydroxyapatite (HAp), and graphene oxide (GO), designated as “BC/HAp/GO”. All components are sourced primarily from agricultural and food waste as alternative means. BC, known for its biocompatibility, fine fiber network, and high porosity, serves as an ideal scaffold material. HAp, a naturally occurring bone component, contributes osteoconductive properties, while GO provides mechanical strength and biofunctionalization capabilities. The biomaterials were analyzed and characterized using a scanning electron microscope, a X-ray diffractometer, and a Fourier transform infrared spectrometer. The produced biocomposite scaffolds were tested for thermal stability, mechanical strength, and biocompatibility. The results showed a nanofibrous, porous network of BC, highly crystalline HAp particles, and well-oxygenated GO flakes with slight structural deformities. The synthesized biocomposite demonstrated promising characteristics, such as increased tensile strength due to added GO particles and higher bioactivity through the introduction of HAp.
