Unlike conventional heterobilayers, homobilayers benefit from the absence of lattice mismatch, enhancing their potential for practical applications. In article number 2400135, Bárbara L. T. Rosa, Stephan Reitzenstein and colleagues unveil the tunable excitonic behavior of these systems through electrical charge carrier concentration control at room temperature. By performing gate-dependent photoluminescence experiments on devices with various twist angles, they demonstrate a twist-angle-dependent doping effect that significantly influences the neutral and negatively charged intralayer excitons. The findings substantially advance the understanding of TMD homobilayers by enabling control over their emission properties, laying a strong foundation for future applications in van der Waals semiconductor devices.\u0000\u0000 <figure>\u0000 <div><picture>\u0000 <source></source></picture>\u0000 </div>\u0000 </figure>","PeriodicalId":100035,"journal":{"name":"Advanced Physics Research","volume":"4 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/apxr.202570013","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143919822","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As sustainability and green chemistry gain prominence, performance improvement and functional design of cellulose gels have attracted growing attention. The macroscopic physical properties of cellulose gels can be shaped by constructing a gel network, which can be regulated by physical methods such as freezing, force induction, and heat treatment to adjust the mechanical properties, transparency, and thermal stability of cellulose. Additionally, structural design and self-assembly of cellulose at the molecular level can endow cellulose gels with diverse functions, such as stretchability, high toughness, ionic conductivity, and self-healing ability. These characteristics give them broad application potential in biomedicine, flexible electronics, adsorption, and food engineering. This article delves into the fundamental concepts, physical properties and design, enhancement methods, molecular strategies, and trending applications of cellulose-based gels across various fields.

An enduring challenge in the constitutive modeling of soft tissue is delicately balancing model complexity, goodness-of-fit, and parameter identifiability, all of which impact the reliability of material behavior predictions under mechanical loading. It is established that biomechanical constitutive models, whether physically motivated or neural network derived, are typically sloppy from the information theory perspective. By analyzing the sensitivity matrix associated with posterior distributions of the constitutive parameters, a consistent pattern revealing the regularity in parameter combinations across experimental protocols characterizing tissue mechanical behavior and prior beliefs with varying levels of informativeness is discovered. The discovered pattern inspires to construct a sloppiness-based parameter hyperspace and proposes a model reduction program that performs model optimization by exploring four sub-hyperspaces. The proposed program offers a guide for effectively simplifying models while tightly ensuring parameter identifiability and prediction accuracy. Clear improvements are showcased to the brain tissue constitutive models discovered by neural networks and a physically motivated constitutive model of the human patellar tendon.","PeriodicalId":100035,"journal":{"name":"Advanced Physics Research","volume":"4 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/apxr.202500002","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144273213","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

HfO₂-based ferroelectric random-access memory (FeRAM) has been extensively studied for its simple structure similar to that of dynamic random-access memory (DRAM) and high power efficiency. However, due to the limited endurance of HfO2 and the high coercive field (Ec) arising from its high energy barrier for polarization switching, the commercialization of the low-power FeRAM faces several challenges. To address these issues, this perspective reviews current scientific approaches and experimental advances aimed at achieving low voltage switching in ferroelectric HfO2 thin films by reducing either Ec or film thickness. Key strategies including controlling types and number of dopants in HfO2, decreasing free energy of the intermediate tetragonal phase, achieving metal-excess rhombohedral phase, controlling oxygen vacancy concentration, and enhancing domain wall motion are reviewed based on theory as well as experimental demonstrations. Especially, recent progress in achieving low voltage operation in ferroelectric HfO2 capacitors via sub-5 nm thickness scaling are highlighted. Overall, the importance of precise material and process control to overcome current technical limitations in device scalability and reliability is emphasized, casting an optimistic outlook on the future of ferroelectric memory technology.","PeriodicalId":100035,"journal":{"name":"Advanced Physics Research","volume":"4 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/apxr.202400194","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144273520","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unlike classical bits that maintain a definite state of 0 or 1, a p-bit fluctuates between these states in a controlled, stochastic manner. This probabilistic behavior allows for the representation and processing of information in a form that leverages inherent randomness. In this study, a unique approach is presented to generating p-bits using a hybrid conjugated polymer, poly-4-((6-(4H-dithieno[3,2-b:2',3'-d]pyrrol-4-yl)hexyl)oxy)-N,N-diphenylaniline (pTPADTP), as a memristive material. The polymer's conjugated backbone, combined with pendant triphenylamine groups, enables the creation of p-bits through random resistance switching. The stochasticity of this polymeric memristor makes it particularly suited for p-bit applications in stochastic optimization, probabilistic algorithms, and artificial neural networks. The charge transport in the polymer is facilitated by two synergistic percolation mechanisms: one occurring along the polymer backbone and the other through the pendant triphenylamine groups. The study of p-bits generated from pTPADTP opens new avenues for advancing both the theory and practice of computation, where uncertainty and randomness are harnessed as valuable computational resources.","PeriodicalId":100035,"journal":{"name":"Advanced Physics Research","volume":"4 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/apxr.202400142","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143818820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
