However, they exhibit rapid capacity degradation induced by transition metal dissolution and structural reconstruction, which are associated with hydrofluoric acid (HF) generation from lithium hexafluorophosphate decomposition. The potential for thermal runaway during the working process poses another challenge. Separators are promising components to alleviate the aforementioned obstacles. Herein, an ultrathin double-layered separator with a 10 μm polyimide (PI) basement and a 2 μm polyvinylidene difluoride (PVDF) coating layer is designed and fabricated by combining a non-solvent induced phase inversion process and coating method. The PI skeleton provides good stability against potential thermal shrinkage, and the strong PI–PVDF bonding endows the composite separator with robust structural integrity; these characteristics jointly contribute to the extraordinary mechanical tolerance of the separator at elevated temperatures. Additionally, unique HF-scavenging effects are achieved with the formation of –CO···H–F hydrogen bonds for the abundant HF coordination sites provided by the imide ring; hence, the layered Ni-rich cathodes are protected from HF attack, which ultimately reduces transition metal dissolution and facilitates long-term cyclability of the Ni-rich cathodes.

By adopting a new perspective on separators, this study presents a feasible and promising strategy for suppressing capacity degradation and enabling the safe operation of Ni-rich cathode materials.</p></div>","PeriodicalId":11783,"journal":{"name":"Engineering","volume":null,"pages":null},"PeriodicalIF":10.1,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2095809924001528/pdfft?md5=985eae51e0a647136423dc185a9f4024&pid=1-s2.0-S2095809924001528-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140776779","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the aim of reducing transgene introgression and controlling reproduction, upscaled disease resistance and reproductive intervention in catfish species have been studied to lower the potential environmental risks of the introgression of escapees as transgenic animals. Taking advantage of the CRISPR/Cas9-mediated system, we succeeded in integrating the cathelicidin gene (<em>As</em>-<em>Cath</em>) from an alligator (<em>Alligator sinensis</em>) into the target luteinizing hormone (<em>lh</em>) locus of channel catfish (<em>Ictalurus punctatus</em>) using two delivery systems assisted by double-stranded DNA (dsDNA) and single-stranded oligodeoxynucleotides (ssODNs), respectively. In this study, high knock in (KI) efficiency (22.38%, 64/286) but low on-target events was achieved using the ssODN strategy, whereas adopting a dsDNA as the donor template led to an efficient on-target KI (10.80%, 23/213). The on-target KI of <em>As-Cath</em> was instrumental in establishing the <em>lh</em> knockout (LH^–_As-Cath⁺) catfish line, which displayed heightened disease resistance and reduced fecundity compared with the wild-type (WT) sibling fish. Furthermore, administration of human chorionic gonadotropin (HCG) and luteinizing hormone-releasing hormone analogue (LHRHa) can restore the reproduction of the transgenic fish line. Overall, we replaced the <em>lh</em> gene with an alligator cathelicidin transgene and then administered hormone therapy to move towards complete reproductive control of disease-resistant transgenic catfish in an environmentally responsible manner. This strategy not only effectively improves consumer-valued traits but also guards against unwanted introgression, providing a breakthrough in aquaculture genetics to confine fish reproduction and prevent the establishment of transgenic or domestic genotypes in the natural environment.</p></div>","PeriodicalId":11783,"journal":{"name":"Engineering","volume":null,"pages":null},"PeriodicalIF":10.1,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2095809924000420/pdfft?md5=44370087181758a7e38b5f9f08adfffa&pid=1-s2.0-S2095809924000420-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139660277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Inherent conflicts exist among architectural aesthetics, building energy consumption, and solar energy harvesting for glazed facades. In this study, we addressed these conflicts by introducing a new dynamic and vertical photovoltaic integrated building envelope (dvPVBE) that offers extraordinary flexibility with weather-responsive slat angles and blind positions, superior architectural aesthetics, and notable energy-saving potential. Three hierarchical control strategies were proposed for different scenarios of the dvPVBE: power generation priority (PGP), natural daylight priority (NDP), and energy-saving priority (ESP). Moreover, the PGP and ESP strategies were further analyzed in the simulation of a dvPVBE. An office room integrated with a dvPVBE was modeled using EnergyPlus. The influence of the dvPVBE in improving the building energy efficiency and corresponding optimal slat angles was investigated under the PGP and ESP control strategies. The results indicate that the application of dvPVBEs in Beijing can provide up to 131% of the annual energy demand of office rooms and significantly increase the annual net energy output by at least 226% compared with static photovoltaic (PV) blinds. The concept of this novel dvPVBE offers a viable approach by which the thermal load, daylight penetration, and energy generation can be effectively regulated.</p></div>","PeriodicalId":11783,"journal":{"name":"Engineering","volume":null,"pages":null},"PeriodicalIF":10.1,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S209580992400064X/pdfft?md5=8d5c784f163f4cb1e5eb3668dd620433&pid=1-s2.0-S209580992400064X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140468056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its specific mechanism and components still require further clarification. experiments with Vero-E6 cells infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) demonstrated that SHHS effectively inhibited viral invasion and proliferation. Complementary experiments using K18-human angiotensin converting enzyme 2 (hACE2) mice exposed to virus-like particles (VLPs) further confirmed that SHHS impeded SARS-CoV-2 entry. Although SHHS did not demonstrate direct antiviral effects in K18-hACE2 mice challenged with SARS-CoV-2, it significantly alleviated pathological damage and decreased the expression of chemokines such as C–C motif ligand (CCL)-2, CCL-3, C–X–C motif ligand (CXCL)-1, CXCL-6, CXCL-9, CXCL-10, and CXCL-11 in the lungs, suggesting that SHHS exerts immunomodulatory and anti-inflammatory effects via the CCL-2–CXCL axis. Additional research using a lipopolysaccharide (LPS)-induced acute lung injury (ALI) and RAW264.7 cell model validated the ability of SHHS to reduce the levels of inflammatory biomarkers, including interleukin (IL)-1β, IL-6, and tumor necrosis factor-α (TNF-α). Using advanced analytical techniques such as ultrahigh-performance liquid chromatography coupled with linear trap quadrupole Orbitrap mass spectrometry (UHPLC-LTQ-Orbitrap-MS) and surface plasmon resonance (SPR), nodakenin was identified as a potent antiviral component of SHHS that targets the 3C-like protease (3CL), a finding supported by the hydrogen–deuterium exchange mass spectrometry (HDX-MS) and molecular docking analyses. Furthermore, nodakenin demonstrated a significant antiviral effect, reducing the viral load by more than 66%.
