Hydrogen-terminated diamond (H-diamond) has emerged as a promising dopant-free p-type semiconductor owing to its distinctive surface conductivity. However, the development of H-diamond-based electronic devices remain constrained by their limited carrier mobility and poor environmental stability. In this work, we developed an innovative approach through conformal deposition of an amorphous carbon (a-C) layer on H-diamond surfaces via microwave plasma chemical vapor deposition. This engineered interface establishes a highly conductive channel exhibiting an unprecedented hole mobility exceeding 1470 cm²V⁻¹ s⁻¹, while maintaining optimal carrier density (∼10¹² cm⁻²) and remarkably low sheet resistance (2300 Ω/□). The modified surface demonstrates exceptional environmental stability, retaining its electrical properties for over two months under ambient conditions while maintaining excellent conductivity at elevated temperatures up to 575 K. Comprehensive characterization through photoluminescence spectroscopy, ultraviolet photoelectron spectroscopy, and comparative vacuum/ambient Hall measurements reveals a charge transfer doping mechanism predominantly mediated by the adsorbed a-C layer, with secondary contributions from ambient molecular species. This breakthrough provides critical insights for designing stable, high-performance H-diamond-based electronic systems for advanced applications in extreme environments.

端氢金刚石（H-diamond）由于其独特的表面导电性而成为一种很有前途的无掺杂p型半导体。然而，h -金刚石基电子器件的发展仍然受到载流子迁移率有限和环境稳定性差的制约。在这项工作中，我们开发了一种创新的方法，通过微波等离子体化学气相沉积在h -金刚石表面上沉积无定形碳（a-C）层。该工程界面建立了一个高导电性的通道，其空穴迁移率超过1470 cm2V−1 s−1，同时保持最佳载流子密度（~ 1012 cm−2）和非常低的片电阻（2300 Ω/□）。改性后的表面表现出优异的环境稳定性，在环境条件下保持其电气性能超过两个月，同时在高达575 K的高温下保持优异的导电性。通过光致发光光谱、紫外光电子能谱和比较真空/环境霍尔测量的综合表征表明，电荷转移掺杂机制主要由吸附的a- c层介导，其次是环境分子物种的贡献。这一突破为在极端环境中设计稳定、高性能的h-金刚石电子系统提供了重要见解。

Polycrystalline diamond wafers are valuable for thermal management and battery cooling systems owing to their high thermal conductivity. However, their grinding is challenged by the anisotropic hardness and wear resistance of the constituent grains. This study introduces a mechanochemical grinding method using NiCr alloy metal-bonded wheels, which improves processing performance by suppressing abrasive oxidation. Compared with pure Fe abrasives, the NiCr alloy abrasives reduce the surface roughness of polycrystalline diamond by 18.986 nm and raise the material removal rate to 18.032 nm/min. First-principles calculations show that higher Ni content significantly accelerates the sp³-to-sp² phase transformation on the diamond surface, promoting the formation of an amorphous carbon layer. This result offers theoretical insight into the role of alloy composition in grinding performance.

由于其高导热性，多晶金刚石片在热管理和电池冷却系统中很有价值。然而，它们的磨削受到组成晶粒的各向异性硬度和耐磨性的挑战。本研究介绍了一种NiCr合金金属结合剂砂轮的机械化学磨削方法，通过抑制磨料氧化来提高加工性能。与纯铁磨料相比，NiCr合金磨料使聚晶金刚石表面粗糙度降低了18.986 nm，材料去除率提高到18.032 nm/min。第一性原理计算表明，较高的Ni含量显著加速了金刚石表面sp3- sp2相变，促进了非晶态碳层的形成。这一结果为合金成分在磨削性能中的作用提供了理论见解。

A bottleneck for high-power light emitting diodes (LEDs), laser diodes (LDs), and other high-power electronics is heat dissipation. To improve this aspect, in this study, diamond heat spreaders are used in conjunction with bonding enhanced by Ar-ion activation and TiC interlayer prior to metallization to reduce thermal resistance. Indeed, a low thermal resistance of the diamond heat spreader of 0.085 K/W was obtained, while for AlN and Al₂O₃, the thermal resistance were 0.35 K/W and 1.16 K/W, respectively. Experimental data and simulations illustrate the enhanced heat dissipation performance of the diamond heat spreader for LEDs, as temperature only reached 55.8 °C at an applied current of 3 A. The results highlight that diamond heat spreaders in conjunction with appropriate bonding strategies are an effective pathway for high-power electronics packaging.

大功率发光二极管（led）、激光二极管（ld）和其他大功率电子产品的瓶颈是散热。为了改善这方面的问题，在本研究中，在金属化之前，将金刚石导热片与ar离子活化增强的键合和TiC夹层结合使用，以降低热阻。金刚石导热片的热阻为0.085 K/W，而AlN和Al2O3导热片的热阻分别为0.35 K/W和1.16 K/W。实验数据和模拟表明，金刚石散热片的散热性能得到了增强，当施加电流为3a时，温度仅达到55.8℃。结果表明，金刚石导热片结合适当的粘接策略是高功率电子封装的有效途径。

In this work, titanate nanobelts (TNBs) were successfully grown via hydrothermal synthesis onto the surface of as-prepared carbon graphite/carbon nanotubes composite material. Titanium (IV) butoxide was used as precursor for the synthesis of TNBs, following a basic hydrolysis-condensation sol-gel reaction. Morphological characterization of the nanocomposites by SEM indicated the achieved good growth of TNBs onto the surface of carbon nanotubes (CNTs) and graphite supports. The specific surface area, determined by BET, increased significantly from pure graphite carbon KS44 (6.23 m²/g) to carbon support KS44/CNT/TNB enriched with TNBs and CNTs (161.67 m²/g). On the other hand, the visible light absorption spectrum increased with TNB-based composites. A remarkable enhancement in absorption in the visible region achieved a 1000% enhancement for KS44/CNT/TNB relative to KS44 alone, which explains the improvement of its photocatalytic degradation capacity of AO7. The results obtained by UV–visible and XPS show that the simultaneous presence of TNBs and CNTs on graphite-based composites (KS44/CNT/TNB) gives the material the necessary properties to be used as an adsorbent and catalyst in wastewater treatment, and in particular for the removal and degradation of azo dyes in aqueous solution.

本研究通过水热法在制备好的碳石墨/碳纳米管复合材料表面成功生长钛酸盐纳米带（TNBs）。以丁氧化钛（IV）为前驱体，经碱性水解-缩合-溶胶-凝胶反应合成tnb。SEM形貌表征表明，纳米复合材料在碳纳米管和石墨载体表面生长良好。BET测定的比表面积从纯石墨碳KS44 （6.23 m2/g）显著增加到富含TNB和CNTs的碳载体KS44/CNT/TNB （161.67 m2/g）。另一方面，tnb基复合材料的可见光吸收光谱增加。与单独的KS44相比，KS44/CNT/TNB在可见光区的吸收显著增强，提高了1000%，这解释了其光催化降解AO7能力的提高。紫外-可见和XPS结果表明，在石墨基复合材料（KS44/CNT/TNB）上同时存在TNB和CNTs使该材料具有必要的性能，可作为废水处理中的吸附剂和催化剂，特别是用于去除和降解水溶液中的偶氮染料。

Diamond has emerged as an ideal substrate material for next-generation high-power semiconductor devices due to its exceptional electronic properties. While self-rotating grinding technology demonstrates high-efficiency material removal, its application is hindered by trajectory aggregation effects, which degrade surface accuracy. This study addresses this bottleneck by establishing a grinding trajectory density distribution model to systematically analyze the influence of workpiece placement (position, angle) and substrate size on trajectory uniformity. Combined with experimental investigations into diamond anisotropic removal characteristics, multi-parameter optimization enabled synchronous processing of five (100) orientation diamond substrates. The results indicate an average material removal rate of 1.75 μm/h, with a surface roughness of Sa < 0.5 nm and a surface flatness of PV < 8 nm. This achievement successfully meets the dual objectives of high quality and high efficiency.

Owing to the elemental abundance and cost-effectiveness of sodium, sodium-ion batteries (SIBs) have emerged as an attractive candidate for large-scale energy storage systems. However, the fabrication of high-performance anode materials remains a critical challenge. Among various options, biomass-derived hard carbon has gained significant research interest due to its environmental friendliness, renewability, and tunable microstructure. Herein, the present research focuses on longan seeds-derived hard carbon (LSHC), specifically studying the correlation between its pyrolysis temperature and the microstructure and electrochemical performance. The data indicate that elevating the thermal treatment temperature led to a higher degree of graphitization (structural order) in HC, accompanied by a decline in surface defects and a growth in closed pore volume. A lower defect density led to the suppression of the solid electrolyte interphase (SEI) film formation, while a greater volume of closed pores was responsible for improving the capacity in the plateau region. Moreover, the correlation between pore structure regulation, ion transport dynamics, and electrochemical properties was systematically studied. Longan seeds-derived HC prepared at 1300 °C exhibits a remarkable reversible specific capacity of 287.4 mAh g⁻¹, and demonstrates outstanding cycling stability with 82.1% capacity retention (236 mAh g⁻¹) after 500 cycles at 2C. Even at a higher current density, the HC exhibits specific discharge capacity of 208 mAh g⁻¹ at 4C. This work supports regulating the microstructure for biomass-derived hard carbon for tuning sodium ion storage behaviors, which contributes to the sustainable development of biomass resources.

由于钠的元素丰度和成本效益，钠离子电池（SIBs）已成为大规模储能系统的一个有吸引力的候选者。然而，高性能阳极材料的制造仍然是一个关键的挑战。在各种选择中，生物质衍生的硬碳由于其环境友好性，可再生性和可调节的微观结构而获得了重要的研究兴趣。本文以龙眼籽衍生硬碳（LSHC）为研究对象，研究其热解温度与微观结构和电化学性能的关系。结果表明，热处理温度的升高使HC的石墨化程度（结构有序度）提高，表面缺陷减少，闭孔体积增大。较低的缺陷密度抑制了固体电解质间相（SEI）膜的形成，而较大体积的封闭孔隙则提高了高原区域的容量。此外，还系统地研究了孔隙结构调节、离子传递动力学和电化学性能之间的关系。在1300°C下制备的龙眼种子衍生的HC具有287.4 mAh g−1的可逆比容量，并且在2C下循环500次后具有82.1%的容量保持率（236 mAh g−1）。即使在更高的电流密度下，HC在4C时也显示出208 mAh g−1的比放电容量。本研究支持通过调控生物质源硬碳的微观结构来调控钠离子的储存行为，从而促进生物质资源的可持续发展。

The metal current collectors are necessary components to mechanically hold the electrode material and to conduct electricity in lithium-ion batteries. However, the metal current collectors are heavy and chemically unstable in electrolyte solution. In this paper, we report the use of freestanding, lightweight, highly conductive and ultrathin graphene papers as current collectors of electrodes in lithium-ion batteries. The graphene paper presents excellent chemical and electrochemical stability comparing to that of the commercial Al and Cu foils, which are generally used as conductive substrates in lithium-ion batteries. The cathode and anode with graphene papers as current collectors exhibit the excellent cycle stability and high specific capacity. Meanwhile, the higher energy density can be achieved using the graphene paper as current collector.

In response to the rapidly increasing demand for natural graphite (NG), this study aimed to explore and diversify new sources of raw materials by processing and purifying NG mined from Southeast Asia and Africa. The physical, chemical, and electrochemical properties of the materials were evaluated to assess their feasibility as anode materials for lithium-ion batteries (LIBs). Through pulverization and spheronization processes, the particle morphology and crystal structure were analyzed. Under the condition of a median particle size (D₅₀) of 11.0 μm, Vietnamese NG exhibited the highest stacking height (

L_{c}

) of 59.4 nm. In addition, electrochemical tests revealed an initial coulombic efficiency of approximately 90% and a discharge capacity of 365.4 mAh/g. Qingbei NG showed an

L_{c}

of 43.4 nm with a discharge capacity of 359.8 mAh/g. These results suggest that crystal structural parameters such as stacking height play a critical role in the lithium-ion intercalation and deintercalation processes, significantly influencing electrochemical performance. Accordingly, this study confirmed the potential for developing NG-based anode materials using regionally diverse sources and highlighted the importance of designing region-specific process optimization strategies in future research.

为了应对对天然石墨（NG）快速增长的需求，本研究旨在通过对东南亚和非洲开采的NG进行加工和提纯，探索和多样化新的原材料来源。对材料的物理、化学和电化学性能进行了评估，以评估其作为锂离子电池（LIBs）负极材料的可行性。通过粉碎和球化工艺，对颗粒形貌和晶体结构进行了分析。在中位粒径（D50）为11.0 μm的条件下，越南NG的最高堆积高度（Lc）为59.4 nm。此外，电化学测试表明，初始库仑效率约为90%，放电容量为365.4 mAh/g。青北NG的Lc为43.4 nm，放电容量为359.8 mAh/g。这些结果表明，晶体结构参数（如堆叠高度）在锂离子的嵌入和脱嵌过程中起着至关重要的作用，显著影响着电化学性能。因此，该研究证实了利用不同地区的资源开发基于天然气的阳极材料的潜力，并强调了在未来研究中设计特定地区工艺优化策略的重要性。

This study reports a novel floating, solar-light-responsive PAN/Ag₃PO₄–gCN nanofiber photocatalyst fabricated via electrospinning, designed to overcome the critical limitations of gCN aggregation, poor recyclability, and inefficient light utilization in aqueous systems. The key novelty lies in integrating an Ag₃PO₄–gCN heterojunction into a hydrophobic PAN nanofiber matrix, producing a low-density, floatable photocatalyst that maximizes solar exposure while minimizing light-shielding effects. Structural and surface characterizations (XRD, FTIR, XPS, SEM, TGA, BET, and UV–Vis) confirmed the successful formation of a well-dispersed heterostructure with strong interfacial interactions and boosted visible-light absorption. Photocatalytic evaluation using methylene blue under solar irradiation demonstrated rapid adsorption and efficient degradation, achieving 94% removal within 60 min under optimized conditions. Kinetic assessment revealed pseudo-first-order behavior with a high apparent rate constant of 0.04189 min⁻¹ for PAN/(0.02)Ag₃PO₄–gCN, attributed to improved charge separation and the development of reactive oxygen species. Importantly, the nanofibers retained 93% degradation efficiency after six cycles, confirming excellent durability and reusability. This work presents a scalable, sustainable approach to tailor immobilized, reusable photocatalysts for wastewater remediation.

Hydrogen is a key clean energy carrier for global sustainability, and solar-driven water-splitting technologies playing a crucial role in producing hydrogen efficiently and reducing dependence on fossil fuels. Graphitic carbon nitride (g-C₃N₄, GCN) catalyst is highly promising for photocatalytic applications due to its visible-light activity, cost-effectiveness, narrow bandgap, non-toxicity, stability, and ease of synthesis. This study focuses on the synthesis of GCN through thermal polymerization, and further explores the effect of boron doping (BCN) on the electronic, optical, and catalytic properties of the resulting material. Photoelectrocatalytic (PEC) measurements show improved photocurrent density, while photocatalytic (PC) measurements show evolution of 518 μmol H₂ per 0.1 g of BCN, which was 1.64 times higher than pristine GCN. Additionally, DFT was done to understand that low B doping concentration is optimum for H₂ evolution, while B substitution of N sites takes place in BCN. Thus, boron doping improves charge separation and enhances light absorption, required for improved PEC/PC performances. These findings, highlight that boron-doped GCN is a viable and cost-effective photocatalyst for solar-driven hydrogen production.

氢是全球可持续发展的关键清洁能源载体，太阳能驱动的水分解技术在高效生产氢和减少对化石燃料的依赖方面发挥着至关重要的作用。石墨化氮化碳（g-C₃N₄，GCN）催化剂具有可见光活性、低成本、窄带隙、无毒、稳定性好、易于合成等优点，在光催化领域具有广阔的应用前景。本研究重点研究了热聚合法制备GCN，并进一步探讨了硼掺杂（BCN）对所得材料的电子、光学和催化性能的影响。光电催化（PEC）测量结果表明光电流密度有所提高，而光催化（PC）测量结果表明每0.1 g BCN的光电流密度为518 μmol H 2，是原始GCN的1.64倍。此外，DFT还发现低B掺杂浓度最有利于H2的演化，而B取代N位点则发生在BCN中。因此，硼掺杂改善了电荷分离，增强了光吸收，这是改善PEC/PC性能所必需的。这些发现突出表明，硼掺杂GCN是一种可行且具有成本效益的太阳能驱动制氢光催化剂。
