Article Abstract

The demand for life cycle assessments (LCA) is growing rapidly, which leads to an increasing demand of life cycle inventory (LCI) data. While the LCA community has made significant progress in developing LCI databases for diverse applications, challenges still need to be addressed. This perspective summarizes the current data gaps, transparency, and uncertainty aspects of existing LCI databases. Additionally, we survey and discuss novel techniques for LCI data generation, dissemination, and validation. We propose key future directions for LCI development efforts to address these challenges, including leveraging scientific and technical advances such as the Internet of Things (IoT), machine learning, and blockchain/cloud platforms. Adopting these advanced technologies can significantly improve the quality and accessibility of LCI data, thereby facilitating more accurate and reliable LCA studies.

Copper ions are essential elements in the human body and participate in various physiological activities in the bodies of organisms. Herein, an ultrasensitive electrochemical biosensor was developed for detection of copper ions (Cu) based on FeO@Au magnetic nanoparticles (FeO@Au MNPs) and a Cu-dependent DNAzyme assisted nicking endonuclease signal amplification (NESA) strategy. dsDNA is formed by a hybridization reaction between DNA S2 and S1 immobilized on the surface of FeO@Au MNPs.

Multimorbidity of chronic diseases is one of the most common health issues among older adults, and the resulting demand for long-term medical care and management imposes a considerable burden on healthcare systems. Muscle strength, a core indicator of overall health status, is closely associated with the risk of developing multimorbidity of chronic diseases in older adults. Decline in muscle strength not only increases the risk of multimorbidity of chronic diseases but also interacts with it to exacerbate disease burden.

The Asiatic apple leafminer, Phyllonorycter ringoniella (Matsumura), is a significant secondary pest of apple trees in Northeast Asia. To better understand its population dynamics, a population model based on temperature-developmental relationships was constructed. This model includes three sub-models: spring emergence, immature stage transition, and adult oviposition.

Engineering Covalent and Noncovalent Interface Synergy in MXenes for Ultralong-life and Efficient Energy Storage.

Xi'an Key Laboratory of Functional Organic Porous Materials, School of Chemistry and Chemical Engineering, Northwestern Polytechnical University, Xi'an, 710129, P.R. China.

MXenes serve as pivotal candidates for pseudocapacitive energy storage owing to sound proton/electron-transport capability and tunable topology. However, the metastable surface terminal properties and the progressive oxidation leads to drastic capacity fading, posing significant challenges for sustainable energy applications. Here, with the aramid nanofiber as the interface mediator, we engineer the thermal reconstruction of MXenes to synergistically introduce interfacial covalent and noncovalent interactions, resulting in a high specific capacitance of 531.

Host immune elimination largely limits the application of oncolytic viruses in clinics. Here, we rationally design a bioactive platelet-based oncolytic adenovirus delivery system. Upon loading adenoviruses, platelets are transformed to a pro-endocytosis status, which facilitates their internalization by circulating tumor cells (CTCs).
