In particular, emerging applications of biologically-derived materials (biomaterials) in PSCs have tremendous potential in enhancing charge transport, device performance, flexibility, long-term stability, sustainability, and circularity strategies. This review discusses the current status and identifies new research directions for biomaterials as either substitutes or composite constituents with other functional materials in charge transport layers and as solvent systems for PSCs. The current understanding of the effect of cellulose on power conversion efficiency (PCE), shape, and long-term stability of PSCs is discussed in terms of surface roughness, wettability, optical properties, defect concentration, and flexibility. Flexible PSCs that utilise biomaterials are advantageous for transportation and widespread implementation, but suffer several other possible adverse effects that lower the PCE due to decreased electron mobility from increased charge traps during bending cycles. Biomaterials have considerable scope in defect passivation, boosting PCE, and long-term stability of PSCs when applied in charge transport layers, particularly as interfacial layers between the electron transport layer and active materials.","PeriodicalId":8066,"journal":{"name":"Applied Materials Today","volume":"197 1","pages":""},"PeriodicalIF":8.3,"publicationDate":"2024-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142178278","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}

In this study, a high-strength HEA, (CoCrNi)(TiAl), is selected and subjected to laser powder bed fusion (L-PBF) and ageing treatment. The microstructural evolution and mechanical property development of the material over a wide range of temperatures are thoroughly investigated. It is found that the as-printed microstructure is dominated by numerous ultrafine cellular structures (∼1 μm) with cell boundaries decorated by AlO nanoparticles, leading to high 0.2% yield strength (YS = 725∼750 MPa) and excellent elongation (>28%) at room temperature. The cellular structures remain up to 700 °C but disappear at or above 800 °C. Ageing at or above 600 °C leads to significant γ′ precipitation with the particle size increasing constantly with increased temperature. The samples containing both cellular structures and coarsened γ′ precipitates (aged at 700 °C) exhibit the highest YS (∼1227 MPa) and ultimate tensile strength (UTS∼1539 MPa) at room temperature and display unprecedented YS at high temperatures, i.e., 949 MPa at 600 °C and 728 MPa at 700 °C, respectively. The exceptional tensile strengths are mainly due to the γ′ precipitates and cell boundaries decorated by AlO nanoparticles which may have acted as strong barriers for dislocation motion. At room temperature, the sample deforms mainly by dislocation slip and formation of stacking faults while at elevated temperatures, deformation becomes increasingly planar as characterized by the formation of increased number of stacking faults and the activation of twinning.","PeriodicalId":8066,"journal":{"name":"Applied Materials Today","volume":"15 1","pages":""},"PeriodicalIF":8.3,"publicationDate":"2024-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142178277","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, the volatile nature of IMT, typically stimulated by a specific threshold voltage, limits its potential use primarily to switch-like applications. To broaden its applications, including in-material data processing, achieving on-demand IMT activation with dynamic memory capability is essential. This study demonstrates on-demand modulation of IMT behavior using spatially confined VO nanochannels, designed by local probe lithography. This approach enables the integration of ultrafast (∼180 ns) volatile switches (on/off ratio >10) and memory storage, from short- to long-term, in a single device. Notably, the threshold voltage was effectively reduced from 5.6 V to 2.8 V by precisely modulating the width of spatially embedded VO nanochannels. The observed memory behavior is attributed to persistent metallic domains and preferential IMT along these channels, as confirmed by optical and Kelvin probe force microscopy. Furthermore, the ability to classify input patterns, even in the presence of noise, was demonstrated using interconnected coplanar nanochannels by leveraging the short-term memory characteristics of the IMT. This report marks a significant step towards on-demand nanoscale manipulation of the IMT dynamics, laying the groundwork for ultrasmall, high-speed, and energy-efficient conventional and neuromorphic nanoelectronics.","PeriodicalId":8066,"journal":{"name":"Applied Materials Today","volume":"8 1","pages":""},"PeriodicalIF":8.3,"publicationDate":"2024-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142178281","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, several key aspects especially superionic solid electrolytes (SEs) and carefully designed electrode configurations still remain a challenge for the development of high performance ASSBs. Herein, a halogen-rich lithium argyrodite, LiPSClBr (LPSCB) with optimized synthesis condition is successfully prepared. Electrochemical impedance spectroscopy and X-ray diffraction illustrate that annealing temperature affects Li-ion dynamics, which guides the formation of LPSCB with a high room-temperature ionic conductivity of 10.7 mS cm. Furthermore, LiNiCoMnO with ZrO dual-functional coating layer (ZrO@NCM) was introduced as cathode active materials (CAMs) to guarantee high-energy-density composite cathode. Correspondingly, a better understanding of the optimization of composite cathode design based on the superionic LPSCB is well elucidated and fast ion/electron transport is achieved by revealing the effect of different CAM fractions in the cathodes on the rate and cycling performance. Specifically, ASSBs with 60 wt.% and 80 wt.% CAM deliver high discharge capacity of 1.1 and 1.95 mAh cm at −20 °C and 60 °C, with corresponding capacity retention of 86.4 % and 69.7 % after 100 and 150 cycles, respectively. This work demonstrates the necessity of customizing CAM fractions depending on the desired applications of ASSBs, and provides an effective cathode modification strategy toward the development of sulfide-based ASSBs with excellent electrochemical performance.","PeriodicalId":8066,"journal":{"name":"Applied Materials Today","volume":"2 1","pages":""},"PeriodicalIF":8.3,"publicationDate":"2024-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142178280","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 technique has been used to synthesize various catalysts like FeOx and MnOx. Adding a post-discharge (PD) step during synthesis has been shown to impart valuable new properties, such as phase transformation, increased specific surface area, and enhanced catalytic activity. Knowing that the PD step mostly impacts the plasma-synthesized solids maturation and can be accelerated if heat is introduced into the system, we now contemplate the possibility of accelerating the GP catalysts synthesis by allowing the solution to be heated by the energy spontaneously provided by the plasma without the necessity to add a PD. To challenge this approach, we subjected FeSO and SnSO precursors to plasma exposure without employing the cooling system usually integrated in the GP set-up and compared the resulting solids with those obtained via conventional GP synthesis involving a PD step. The findings show that for iron precursors, the absence of cooling accelerates the formation of non-catalytically active phases and causes particle agglomeration, which is undesirable. However, for tin precursors, the absence of a cooling system introduces features that further improve the catalytic activity of the solids. Precisely, tin oxide phases developed better than other less-catalytically active ones without affecting the textural properties of the solid. This suggests that in some cases, eliminating the PD step can simplify the GP catalyst synthesis process and reduce its environmental and economic impact.","PeriodicalId":8066,"journal":{"name":"Applied Materials Today","volume":"10 1","pages":""},"PeriodicalIF":8.3,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142178282","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, the effectiveness and safety of existing methods often face some limitations. Nanotechnology has emerged as a solution, enabling the design of nanosystems that can effectively deliver drugs. These nanosystems address challenges such as low drug stability and solubility, as well as the lack of tumor targetability. While nanomaterials offer advantages, certain nanoparticles have their own limitations, which has prompted researchers to explore innovative drug delivery systems. One promising avenue is the use of extracellular vesicles (EVs), which are natural nanoparticles secreted by cells. EVs possess biocompatibility, stability, and targeting capabilities, making them ideal candidates for drug carriers. However, challenges still remain in this field. These include limited production yield, complexity, inefficient cargo loading, and controlled release of drugs. To overcome these challenges, researchers have been employing engineering techniques to modify the structures of EVs, enhancing their intrinsic properties. Surface modification and hybrid systems that combine EVs with other structures have shown potential in addressing these limitations. This review focuses on the landscape of EVs and their crucial role in cancer therapeutics and diagnosis. It begins by exploring the biological functions and properties of EVs.
