Although there are many computational methods to identify cancer lncRNAs, they do not comprehensively integrate multi-omics features for predictions or systematically evaluate the contribution of each omics to the multifaceted landscape of cancer lncRNAs. In this study, an algorithm, POCALI, is developed to identify cancer lncRNAs by integrating 44 omics features across six categories. The contributions of different omics are explored to identifying cancer lncRNAs and, more specifically, how each feature contributes to a single prediction. The model is evaluated and benchmarked POCALI with existing methods. Finally, the cancer phenotype and genomics characteristics of the predicted novel cancer lncRNAs are validated. POCALI identifies secondary structure and gene expression-related features as strong predictors of cancer lncRNAs, and epigenomic features as moderate predictors. POCALI performed better than other methods, especially in terms of sensitivity, and predicted more candidates. Novel POCALI-predicted cancer lncRNAs have strong relationships with cancer phenotypes, similar to known cancer lncRNAs. Overall, this study facilitates the identification of previously undetected cancer lncRNAs and the comprehensive exploration of the multifaceted feature contributions to cancer lncRNA prediction.","PeriodicalId":229,"journal":{"name":"Small Methods","volume":" ","pages":"e2401987"},"PeriodicalIF":10.7,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144126314","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the reversible and irreversible oxidation behaviors of 7,8-dihydroxyphenazine-2-sulfonic acid (DHPS) are investigated through in situ UV-vis and ex situ transient absorption spectra. It turned out that the high alkaline concentrations can effectively reduce the reversible auto-oxidation rate, however, it would also accelerate the irreversible oxidation reaction triggered by the photoexcited singlet oxygen (1O2) when under irradiation. As a result, combining the reducing agents and employing light-proof storage tanks can improve the cycle life of AOFBs effectively. Batteries encapsulated and operated outside the glove box can achieve a stable operation with a Coulombic efficiency of over 99% and a capacity decay rate of 0.0054%/cycle for 2500 cycles.

However, LMBs are severely hindered by the unstable solid electrolyte interphase (SEI), which requires a rational design of interface engineering. Herein, a dual protection strategy of Li-metal anode is proposed via coating a black phosphorus (BP) layer on the separator. During the battery assembly process, few-layer BP nanosheets can be peeled off and uniformly modified on the lithium metal surface, due to the soft metallic properties of lithium, meanwhile, the remaining BP remains on the separator, so that they provide two types of protection during the initial formation and cycling processes, respectively. During initial lithiation, the stripped BP is converted to Li3P, which is a beneficial component for stable and fast-dynamic SEI. In addition, when Li dendrites are dramatically generated under extreme conditions, the BP modified on the separator can melt Li dendrites owing to the high activity of their alloying reaction. Therefore, the BP-modified separator facilitates the large-scale application of Li metal, with generalisability in both ester and ether electrolytes. In the ester electrolyte, the lifetimes of Li||Li cells are prolonged to over 2200 h, and Li||LiFePO4 cells exhibit a superior capacity retention of 78% after 500 cycles at 1 C.","PeriodicalId":229,"journal":{"name":"Small Methods","volume":" ","pages":"e2500201"},"PeriodicalIF":10.7,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144118491","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, the dual charge storage mechanism in VSSe@C is unveiled, combining K+ intercalation and interfacial supercapacitive space charge storage mechanism. The abundant VSSe/carbon interfaces within the confined space in the carbon nanofiber are directly captured by 3D electron microscopy, and this rich interface enables decoupled electron transport (via carbon) and potassium ion (K+) transport (via VSSe), triggering interfacial supercapacitive space charge storage mechanism in addition to the K+ intercalation. This dual mechanism endows the VSSe electrode to achieve a reversible specific capacity of 309 mAh g-1 with negligible volumetric expansion (0.86%) and no phase degradation. Benefiting from these features, the ultrahigh stability for over 5000 cycles with a capacity retention of 83.3% at 2 A g-1 is demonstrated, and the application of VSSe@C in the potassium pouch cell with perylene-3,4,9,10-tetracarboxylic dianhydride (PTCDA) cathode is further validated.

Due to its ultrahigh ion conductivity and moderate ion selectivity, the crystalline covalent organic framework (COF) monolayer demonstrates the record-high output power density by mixing river water and seawater. To further improve energy conversion performance, it is necessary to enhance ion selectivity while achieving high membrane permeability. Here, a layer-by-layer stacking approach is developed to notably enhance the selective ion transport of ultra-thin COF layers, offering advantageous in both conversion efficiency and scalability. Under a standard NaCl salinity gradient (0.5 M/0.1 M), the ratio of ionic mobility between Cl- and Na+ increases from 1.4 to 2.9 with stacking the anion-selective COF monolayer from one to ten layers, leading to a more than seven-fold enhancement in osmotic energy conversion efficiency. By maximizing selectivity and permeability, the output power can reach 411 pW by stacking three layers in a single device.

The past decade has since witnessed the development of various nanoplasmonic technologies to empower EV analysis, through bulk and single-vesicle characterization, at an unprecedented scale and resolution. These platforms achieve versatile measurements that are not only size-matched to EV dimensions but can also probe multiplexed biomolecular contents, thereby providing new insights into EV heterogeneity and enabling transformative clinical opportunities.
