Their unique geometrical and electronic structure give them excellent electrochemical properties. The larger specific surface area and ion-diffusion channels in pores can provide more storage sites for alkali metal ions and increase the diffusion rate of electrons and ions. Hence, GDY-based materials possess broad prospects in electrochemical energy storage and have gained more favor as anode materials for alkali ion batteries. Here, we have made a systematic summary of GDY-based materials and their derivatives, including the geometrical and electronic structures, synthesis, modifications, and storage mechanisms of Li+/Na+/K+, along with the applications in Li+/Na+/K+ batteries. In view of the current situation, the large-scale application of GDY-based materials as anodes in alkali ion batteries is still a great challenge. We hope that this work can provide a theoretical basis for GDY-based materials with superior performance, more convenient and safer preparation, and higher yield.","PeriodicalId":54222,"journal":{"name":"Nano Futures","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2022-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46668926","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The rich stroma in tumor tissue is a major barrier to drug penetration and tumor killing. Cisplatin and cisplatin-based nano-delivery systems are widely used as chemotherapeutic agents. However, the side effects and the inability of permeating tumor tissue in depth have limited their application in the clinic. Hyaluronan is an important component of the extracellular matrix in the tumor tissue and has the potential to be targeted for tumor stroma degradation. Therefore, a nanocarrier-mediated cisplatin co-delivery system BPEI-SS-Pt/HAase@CaP consisting of hyaluronidase (HAase) and polymer-cisplatin conjugate BPEI-SS-Pt through disulfide bonding to branched polyethyleneimine (BPEI) was constructed. In the construction of the co-delivery system of BPEI-SS-Pt and HAase, amorphous calcium phosphate is introduced to obtain the tumor microenvironment responsive release of HAase. The particle size of optimized BPEI-SS-Pt/HAase@CaP nano-complexes is 143 ± 14 nm. In the tumor microenvironment, BPEI-SS-Pt/HAase@CaP nano-complexes were able to release HAase to degrade the hyaluronan in the tumor stroma. The results of histochemical and fluorescent labeling showed that hyaluronan was degraded in vivo by BPEI-SS-Pt/HAase@CaP and the nanocarrier-mediated BPEI-SS-Pt can be easily across the loosened stroma and penetrated the tumor tissue more deeply compared with BPEI-SS-Pt without loading HAase. When they were uptaken into tumor cells and responded to high glutathione in the intracellular environment to release cisplatin, more effective chemotherapy to pancreatic cancer was obtained. Compared with the free cisplatin or BPEI-SS-Pt group, BPEI-SS-Pt/HAase@CaP nano-complexes achieved the best antitumor effect in vivo, promising the future clinic use of cisplatin for effective chemotherapy to pancreatic cancer.","PeriodicalId":54222,"journal":{"name":"Nano Futures","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2022-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49366088","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

So far the proposed circuits are restricted to a single-orbital tight-binding model with different lattices. Here, we introduce the concept of a multi-orbital topolectrical circuit and construct practical LC circuits to demonstrate its superiorities. As a proof of concept, we assemble two sets of inductors in one plaquette to simulate a (px, py )-orbital model within a two-dimensional hexagonal lattice. In the presence of spin–orbit coupling, as generated by mixing voltage degrees of freedom, a quantum spin Hall (QSH) state emerges with spin-resolved edge modes propagating along the boundary in the time domain. Implementation of negative impedance converters (NICs) with nonreciprocal links transforms the circuit into a quantum anomalous Hall (QAH) state. Remarkably, we demonstrate that QSH/QAH states can be reversibly switched by tuning the resistance of NIC, and an experimental observable-edge distance ratio is proposed to facilitate the phase transition detection. This work provides an exciting playground for exploring multi-orbital physics in topolectrical circuits, paving the way for future applications in nanoelectronics, telecommunications, signal processing and quantum computing.","PeriodicalId":54222,"journal":{"name":"Nano Futures","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2022-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48498805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we design and fabricate a type of truncated hollow sub-microsphere via organic colloidal template etching/heating and layer-by-layer isotropic deposition. The as-prepared truncated hollow sphere is of one circular open pore through the shell layer and built of Pt, Ag and Au shell layers from inside to outside. They are controllable in sphere diameter, circular open pore size and shell thickness, which depend on the template and deposition conditions. Further experiments have shown that the Ag sandwich layer and post-deposition ageing process are crucial to obtaining strong and complete truncated hollow sub-microspheres. Their formation is attributed to the template geometry and nearly isotropic deposition. Due to the catalytic Pt layer on the inner surface and the truncated hollow spherical structure, such Pt–Ag–Au hollow spheres are demonstrated to be chemically propelled colloidal motors, which can directionally move in H2O2-containing solutions. This study presents a controllable route for mass-fabricating heterogeneous multi-layer truncated hollow sub-microspheres, and provides a new type of chemically self-propelled colloidal motor.","PeriodicalId":54222,"journal":{"name":"Nano Futures","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2022-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45524554","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Research on the optical properties of nanofluids for application in direct absorption solar collectors (DASCs) is progressing at a burgeoning speed. In a DASC system, nanofluid with high optical absorptivity can convert the incident solar energy into the thermal energy of the fluid. The dispersed nanoparticles in the fluid act in the process through the phenomenon of absorption and scattering. Studies conducted on the optical property characterization of monocomponent nanofluids have become saturated. Moreover, the photothermal efficiency (PTE) of the nanofluid can be enhanced by using multicomponent nanofluids. Nanofluids prepared using varying materials, shapes and sizes of nanoparticles can tune the absorption spectra of the bulk fluid to improve the PTE. A hybrid nanocomposite can similarly enhance the absorptivity due to the synergy of materials present in the nanocomposite particle. In this review, a comprehensive survey on the synthesis and optical characterization of different monocomponent, blended and hybrid nanocomposite nanofluids has been performed.","PeriodicalId":54222,"journal":{"name":"Nano Futures","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2022-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45536706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
