However, research on n-type doping remains limited. This paper reviews the main n-type doping methods for diamond: ion implantation (I/I), chemical vapor deposition (CVD), high pressure–high temperature (HPHT), deuterated method (DM), surface charge transfer doping (SCTD), and laser irradiation (LI). It analyzes the parameters, advantages, and disadvantages of each technique while classifying common single-element and multi-element co-doping methods. Single-element dopants include Group IA (Li, Na, K), Group ⅡA (Be, Mg), Group VA (N, P, As, Sb), and Group ⅥA (O, S, Se, Te) elements. Multi-element co-doping often combines B-P, B-S, B-O, and B-N pairs. Additionally, we examine the atomic structures of these dopants, introduce commonly used simulation models, and compare the electronic characteristics of synthesized n-type doping diamonds. Finally, we summarize the challenges of n-type doping diamond in doping equipment, processes, and electronic devices, and propose possible improvements and future development directions.</p></div>","PeriodicalId":506,"journal":{"name":"Carbon Letters","volume":"35 5","pages":"1981 - 2009"},"PeriodicalIF":5.8,"publicationDate":"2025-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145230343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, there is an urgent need to consider recycling and transformation of these waste tires into functional materials while promoting the circular economy and environmental sustainability. Recent advancements in material science research have highlighted the potential of converting waste tires into valuable porous carbon materials based on their rich carbon polymeric composition. Among the various conversion techniques, carbonization and activation have been shown to yield microporous, mesoporous and macroporous carbon with a large specific surface area up to 2450 m<sup>2</sup>g<sup>−1</sup> with doped heteroatoms (P, B, N and O) that enhances its surface chemistry in diverse applications. Thus, this review looks to investigate various processes involved in converting waste tires into high-performance porous carbon for electrocatalysis, adsorbents, catalyst support, and electrodes for energy storage devices. It also highlights the recent trend of tire compositions, tire chemistry in terms of vulcanization and devulcanization towards a greener economy.

However, their inherent surface limitations—poor chemical stability, insufficient active sites, and limited functionality—restrict their full potential. Chemical vapor deposition (CVD) has risen as a game-changing post-synthesis modification strategy, enabling atomic-scale precision in surface engineering. This is also impactful for carbon-based nanofibers, where surface inertness limits their electrochemical performance. This review critically examines advanced CVD techniques, including atomic layer deposition (ALD), plasma-enhanced CVD (PECVD), and initiated CVD (iCVD), which enable the formation of conformal coatings, hierarchical functionalization, carbon nanotube integration, and interfacial optimization of as-spun nanofibers. We highlight breakthroughs in hydrophobicity, catalytic activity, biocompatibility, and energy storage performance, with applications ranging from oil–water separation to nerve gas detoxification, pH-responsive drug delivery, and high-capacity carbon-composite lithium-ion batteries. By dissecting deposition mechanisms, material innovations, and emerging applications, this work highlights the synergy between as-spun nanofibers and the exploitation of CVD techniques in designing versatile materials. Furthermore, advancements hinge on computational modeling, novel precursors, including carbon-rich sources, and scalable processes to bridge lab-scale innovations with industrial deployment are desired. This comprehensive analysis provides a guiding framework for researchers utilizing CVD techniques as a post-modification tool to develop nanofiber-based solutions addressing global challenges in sustainability, healthcare, and energy.</p></div>","PeriodicalId":506,"journal":{"name":"Carbon Letters","volume":"35 5","pages":"1933 - 1953"},"PeriodicalIF":5.8,"publicationDate":"2025-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145230262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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, we investigated the wetting behavior of an ultrathin LIG synthesized from a fluorinated polyimide (F-PI) thin-film precursor using ultraviolet (UV) laser irradiation. Systematic variations in laser exposure induced morphologic transitions from hierarchical porous networks to compact planar structures, accompanied by changes in the chemical composition, including fluorine depletion and oxygen incorporation. These combined effects result in a broad range of wetting behaviors, including superhydrophobicity and hydrophilicity. Remarkably, LIG produced under single irradiation exhibited a rose-petal-like wetting state characterized by a high contact angle and strong droplet adhesion, a phenomenon not previously reported in LIG systems.
