Phase-change capsules (PCCs) are promising dispersoids for flexible energy storage and delivery; however, their thin shells compromise structural stability, limiting their fabrication to the micro- or nano-scale and restricting practical applications. Herein, we introduce hydrophilic milliscale PCCs (HMPCCs) as a pragmatic solution for efficient thermal energy delivery and antifouling in TENs. HMPCCs feature a thin shell and internal three-dimensional radially conductive and adsorptive frameworks with hierarchical pores (80% porosity), which provide enhanced thermal conductivity; a high adsorption capacity for Ca<sup>2+</sup>, Mg<sup>2+</sup>, and Fe<sup>3+</sup> ions; and efficient phase-change material encapsulation without leakage. Incorporating clinoptilolite nanoparticles into the HMPCCs further increases the thermal conductivity, supplements the adsorption capability for Ca<sup>2+</sup> and Mg<sup>2+</sup> ions, and optimizes the bulk density for stable dispersion in water. HMPCCs achieved 100% removal efficiency for scaling cations (0.1–1.0 mg L<sup>–1</sup>) and exhibited excellent durability, maintaining structural integrity after 1000 phase-change cycles. A thermodynamic analysis confirmed that the adsorption process was endothermic, spontaneous, and thermodynamically favorable. Regeneration via low-energy desorption ensures its reusability and economic viability. These findings suggest that HMPCCs represent a scalable and sustainable solution for advanced TEN applications and have outstanding thermal management and antifouling capabilities.","PeriodicalId":11783,"journal":{"name":"Engineering","volume":"52 1","pages":""},"PeriodicalIF":12.8,"publicationDate":"2025-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144919003","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A therapeutic paradigm shift is emerging towards the EV-based treatment of nerve injury. Accumulating evidence indicates that EVs promote nerve regeneration and functional recovery, primarily by modulating neural cell function, immune-inflammatory responses, and angiogenesis. Various strategies have been developed to incorporate EVs into nerve grafts or to utilize them as diagnostic and therapeutic vehicles.

However, unilateral climate policies risk carbon leakage through the relocation of emission-intensive industries, potentially undermining their intended benefits. Herein, we couple an integrated assessment model with a simple climate model to quantify the carbon leakage associated with China’s CN by 2100 and assess its impact on global warming. The results show that China achieving CN will lead to carbon leakag of 6.9% to 14.9%. While the emissions-level changes appear modest, the leakage leads to an increase in CO<sub>2</sub> concentrations, rising from 2.1 ppm in the target year to 7.7 ppm by 2100. The global cooling effect of China’s CN is 0.15–0.19 °C, with leakage weakening this effect by 0.02 °C. Increased carbon sink capacity mitigates 8.9%–11.3% of the warming caused by leakage, and synergistic reductions in methane and nitrous oxide emissions offset over 70.5% of the leakage-induced warming. Therefore, solutions to carbon leakage should go beyond merely preventing increased emissions and focus on offsetting the broader climate impacts caused by leakage. These findings underscore the critical importance of addressing carbon leakage in climate policy design to mitigate the risks of global warming and maximize the benefits of CN efforts.","PeriodicalId":11783,"journal":{"name":"Engineering","volume":"54 1","pages":""},"PeriodicalIF":12.8,"publicationDate":"2025-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144906012","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we introduce a novel strategy for discovering aging-associated IgG glycans and establish a prediction model on the basis of their absolute concentration alterations. We employed glycomic quantification technology to identify alterations in the amount of IgG glycan in natural aging and antiaging (caloric restriction (CR)) models and discovered aging-related glycans. The glycomic analysis revealed key features: downregulation of the bisected glycan GP3 (F(6)A2B) and upregulation of the digalactosylated glycan GP8 (F(6)A2G2). These glycan changes showed significant fold changes from an early stage. Using external standards of these two glycans, we subsequently measured their absolute concentrations, allowing for us to establish a predictive model, abGlycoAge, for biological aging. The abGlycoAge index suggested a younger state under CR, with an average age reduction of 3.9–14 weeks. Additionally, RNA sequencing of splenic B cells revealed that <em>Derl3</em>, <em>Smarcb1</em>, <em>Ankrd55</em>, <em>Tbkbp1</em>, and <em>Slc38a10</em> may contribute to alterations in GP3 and GP8 during the aging process. In a preliminary therapeutic study, we tested IgG modified with young signature N-glycans (IgG-Ny). High-dose IgG-Ny showed promising results, alleviating aging-related physiological declines, including reductions in inflammatory markers and improvements in organ senescence, particularly in the brain, kidney, and lungs. This research provides new insights into glycan changes during aging and lays the groundwork for potential antiaging therapies. GP3 and GP8 may serve as biomarkers for aging, offering new perspectives on aging mechanisms and therapeutic approaches.","PeriodicalId":11783,"journal":{"name":"Engineering","volume":"24 1","pages":""},"PeriodicalIF":12.8,"publicationDate":"2025-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144906014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The process was optimized by varying key reaction parameters, including extraction temperature, reaction duration, NaOH concentration, and waste glass fineness. The resulting silicate precursors, which demonstrated high CO<sub>2</sub> capture efficiency, were used to prepare NSA particles. The synthesized NSA exhibited an extremely high surface area and porosity; thus, these can be used as a value-added, lightweight, and reactive supplementary cementitious material for producing thermally insulating concrete. The incorporation of NSA accelerated hydration, with nucleation and pozzolanic effects contributing to 21% and 3%, respectively, to the hydration process. The initial hydration acceleration was attributed to the extremely high surface area of NSA, which facilitated the precipitation of hydration products on its surface. At later stages of hydration, the pozzolanic reaction of NSA promoted the formation of calcium silicate hydrate (C-S-H) in the cement matrix. This reaction increased the chain length of the C-S-H gel, resulting in a more robust and interconnected gel network. The densification effect mitigated potential mechanical property losses caused by the porous nature of NSA. Additionally, the porous structure of NSA significantly reduced the matrix density, leading to lower thermal conductivity and improved insulation performance. This study presents a new approach for valorizing recycled glass, promoting CO<sub>2</sub> sequestration, and producing high-value aerogels for use as additives in the development of lightweight insulating concrete.","PeriodicalId":11783,"journal":{"name":"Engineering","volume":"23 1","pages":""},"PeriodicalIF":12.8,"publicationDate":"2025-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144906011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Particularly in galvanometer-based laser processing systems, the requirement for multiple-step coordinate conversion further complicates the alignment procedure, thereby increasing the potential for error accumulation. To address the alignment issues during galvanometer laser scanning, this paper proposes an alignment-error-free solution for full-<em>in-situ</em> imaging and laser processing system, which eliminates the alignment error at the principal level by skipping the coordinate conversion and directly extracting angular coordinates for laser scanning from the captured images. Compared with the existing galvanometer-based laser processing systems, the main advantage of the proposed method is its ability to achieve alignment-error-free without requiring calibration, making it particularly suitable for small-batch, highly customized, and complex processing tasks. This system specifically facilitates in-line inspection, detection, and measurement during laser fabrications. Furthermore, two experimental cases in pan-semiconductor manufacturing, which includes flexible printed circuits (FPC) cutting and Micro-LEDs defect detection, have been conducted to demonstrate the validation of the proposed full-<em>in-situ</em> processing system. Correspondingly, the current experimental comparisons highlight the superiority of the proposed system for simultaneously achieving a maximum range of 27 mm × 27 mm and a minimum resolution of 0.412 µm, with a maximum processing error <15 µm. Demonstrations in detecting and processing the complex patterns illustrate its exceptional capabilities in alignment-error-free laser processing for precision manufacturing.","PeriodicalId":11783,"journal":{"name":"Engineering","volume":"16 1","pages":""},"PeriodicalIF":12.8,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144900642","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
