Increased generation and release of CO<sub>2</sub> into the atmosphere exacerbates global warming and impedes environmental sustainability. One of the strategies to combat the unpleasant impact of CO<sub>2</sub> in the atmosphere is the conversion of CO<sub>2</sub> into useful products. This study reviews the benefits, drawbacks, and recommendations for effectively utilizing conventional, hybrid, and novel technologies for converting CO2 into energy and chemical products. The deficiencies noticed with chemical, thermal, biological, and catalytic CO<sub>2</sub> conversion technologies (CTs) necessitated the use of hybrid conversion technologies such as biochemical, electrochemical, photocatalytic, and plasma chemical. The study posits that the development and deployment of novel CO<sub>2</sub> CTs like bio-electrochemical, photo-electrochemical, and artificial photosynthesis will advance the research domain and revolutionize product formation. The transformation of CO<sub>2</sub> into renewable fuels such as methane, syngas, and C2 fuels and chemical products such as methanol, formic acid, dimethyl carbonate, oxygenates, formaldehyde, and hydrocarbons is, eco-friendly, reduces air pollution, mitigates climate change, supports energy security, and provides valuable feedstocks for industries. The study recommends optimization of process parameters and reactor design configurations, increased funding, provision of regulatory framework and support, and partnerships among academia, industry players, and government agencies to achieve cost reduction, reduce environmental impacts, and combat drawbacks associated with CO<sub>2</sub> CTs.</p></div>","PeriodicalId":51136,"journal":{"name":"Nanoscale Research Letters","volume":"20 1","pages":""},"PeriodicalIF":5.5,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1186/s11671-025-04214-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143388690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By leveraging the floating body effect, this architecture eliminates the need for capacitors, thereby improving integration density and memory performance. Through Sentaurus technology computer-aided design simulations, we compare the PE NS 1T-DRAM device with a conventional NS 1T-DRAM device to evaluate its effectiveness. The results reveal superior retention time (RT) and sensing margin (SM) performance of the proposed PE NS 1T-DRAM device, surpassing the memory criteria outlined by the International Roadmap for Devices and Systems, which requires an RT exceeding 64 ms at 358 K. This enhanced performance of the proposed device is attributed to its extension region, which functions as a potential well for efficient hole storage, as well as the suppression of Shockley‒Read‒Hall recombination. The PE NS 1T-DRAM device also demonstrates robustness to disturbances, maintaining over 89% of its SM and RT under diverse conditions. This superiority is again attributed to its extension region, which minimizes the effects of current flow and electrostatic potential rise. These results highlight the potential of the PE NS 1T-DRAM design for future high-density memory applications.</p></div>","PeriodicalId":51136,"journal":{"name":"Nanoscale Research Letters","volume":"20 1","pages":""},"PeriodicalIF":5.5,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1186/s11671-025-04201-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143373245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent single-molecule experiments on IsdB interaction with cell adhesion factors revealed an increase of the complex lifetime upon applying a stronger force (catch bond); this was suggested to favor host invasion under shear stress. An increased bond strength under mechanical stress was also detected by Atomic Force Spectroscopy (AFS) for the interaction between IsdB and Hb. Structural information on the underlying molecular mechanisms at the basis of this behaviour in IsdB-based complexes is missing. Here, we show that the single point mutation of Pro173 in the IsdB domain responsible for Hb binding, which weakens the IsdB:Hb interaction without hampering heme extraction, totally abolishes the previously observed behavior. Remarkably, Pro173 does not directly interact with Hb, but undergoes <i>cis–trans</i> isomerization upon IsdB:Hb complex formation, coupled to folding-upon binding of the corresponding protein loop. Our results suggest that these events might represent the molecular basis for the stress-dependence of bond strength observed for wild type IsdB, shedding light on the mechanisms that govern the capability of SA to infect host cells.</p></div>","PeriodicalId":51136,"journal":{"name":"Nanoscale Research Letters","volume":"20 1","pages":""},"PeriodicalIF":5.5,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1186/s11671-025-04182-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143361857","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding the complexities of tumor development and mutation is the need of the hour for the advancement of targeted therapies in cancer care. A significant innovation in this area is the use of nanotechnology, specifically nanoparticles, to tackle various challenges in cancer treatment. Iron oxide nanoparticles stand out in both therapeutic and diagnostic applications, offering a versatile platform for targeted drug delivery, hyperthermia, magneto-thermal therapy, and combinational therapy using modulation of ferroptosis pathways. These nanoparticles are easy to synthesize, non-toxic, biocompatible, and display enhanced circulation time within the system. They can also be easily conjugated to anti-cancer drugs, targeting agents, or genetic vectors that respond to specific stimuli or pH changes. The surface functionalization of these nanoparticles using bioactive molecules unveils a promising and effective nanoparticle system for assisting osteosarcoma therapy. This review will summarize the current conventional therapies for osteosarcoma and their disadvantages, the synthesis and modification of iron oxide nanoparticles documented in the literature, cellular targeting and uptake mechanism, with focus on their functionalization using natural biomaterials and application strategies towards management of osteosarcoma.
