Graphene nanomaterials have become the focus of scientific research and development activities due to unique physical and chemical properties. A widespread technique for the large-scale synthesis of graphene nanoparticles is referred to as "Hummer's" method. This process often produces hydrophilic functionalized graphene-based materials, referred to as graphene oxide (GO) and reduced graphene oxide (r-GO). It relies on the use of oxidation steps to achieve exfoliation of graphite micromaterials as raw resources to obtain graphite oxide also known as graphitic acid followed by further exfoliation techniques to attain GO materials. The different exfoliation degrees can be obtained by various standard amounts of chemical acids, which lead to different functional groups containing oxygen at various degrees of oxidation, which have effects on the electrochemical and physic-chemical characteristics. Understanding the structure of such graphite oxide has been involved in advancing the synthesis chemical methods, paving the way for the development of diverse graphene-based materials Therefore, the chemical synthesis progress based on Hummer's” approaches to prepare graphene nanomaterials have been reviewed. Also, development directions and the existing challenges are explained for pretreatment and surface functional modification for such nanomaterials.

石墨烯纳米材料由于其独特的物理和化学性质，已成为科学研究和开发活动的热点。大规模合成石墨烯纳米颗粒的广泛技术被称为“悍马”方法。该工艺通常会产生亲水性功能化石墨烯基材料，称为氧化石墨烯（GO）和还原氧化石墨烯（r-GO）。它依赖于使用氧化步骤来实现石墨微材料的剥落，作为原料资源，以获得氧化石墨，也称为石墨酸，然后通过进一步的剥落技术来获得氧化石墨烯材料。不同标准量的化学酸可以获得不同的剥离程度，从而导致不同氧化程度的含氧官能团不同，这对电化学和物理化学特性都有影响。了解这种氧化石墨的结构有助于推进化学合成方法的发展，为开发各种石墨烯基材料铺平了道路。因此，本文综述了基于Hummer方法制备石墨烯纳米材料的化学合成进展。阐述了纳米材料的预处理和表面功能改性的发展方向和存在的挑战。

The misuse of benzodiazepines, often implicated in drug-facilitated crimes, presents a significant global concern, profoundly affecting public health and safety. In response to the growing need for rapid, sensitive, and on-site detection methods, this review aims to critically evaluate the current landscape of electrochemical sensing of benzodiazepines. The main objective is to consolidate fragmented research findings on a singular platform and trace the progression of carbonaceous nanohybrid materials from early 3D frameworks to modern 0D structures into a cohesive overview that highlights emerging trends and innovations. We also aim to evaluate how this transformation has enhanced sensor performance. Unlike previous reviews that predominantly focus on conventional gold-standard techniques such as chromatographic and spectroscopic methods, this work focuses exclusively on electrochemical sensing as a promising, portable, and real-time alternative. This evolutionary approach has led to considerable improvements in sensitivity, selectivity, and portability, making these systems increasingly suitable for field-deployable applications. By highlighting key advances especially in graphene oxide (GO), carbon nanotubes (CNTs), fullerenes, quantum dots (QDs) and their metal-oxide-supported nanocomposites, this review underscores how nanostructure dimensionality directly influences electrochemical response. Furthermore, it explores the integration of these advanced materials into smart sensing platforms including those with AI-enabled features, positioning them as next-generation solutions. This work not only maps current advancements but also identifies future research directions bridging the gap between laboratory research and deployable forensic tools.

FiberForm, the substrate of the Phenolic Impregnated Carbon Ablator (PICA), contains various fundamental forms of carbon, including vitreous or highly ordered graphitic regions in the carbon fiber core and amorphous or turbostratic carbon in the binder material, which provides stiffness to the material. In this study, we use the AIREBO potential to investigate the effect of pitting on the elastic properties of carbon fiber (CF) and amorphous carbon (AC). The generation, structural characterization, and loading of pristine AC and CF are compared with their pitted counterparts over a range of densities (1.27 g/cm³ to 2.93 g/cm³) and porosities. Results show a reduction of up to 18.7% in elastic modulus for AC and a reduction of 13.7% in modulus for CF. We also observe AC to have weaker tensile behavior for both oxidized and pristine states, supporting the hypothesis that FiberForm is likely to fail at the binder. The present work advances fundamental understanding of the coupling between oxidation and mechanical behavior of carbon-based TPS materials and serves as a basis for larger-scale simulations.

酚醛浸渍碳烧蚀器（PICA）的基材FiberForm含有各种基本形式的碳，包括碳纤维芯中的玻璃状或高度有序的石墨区域，以及粘合剂材料中的非晶态或涡层碳，这为材料提供了刚度。在这项研究中，我们使用AIREBO电位来研究点蚀对碳纤维（CF）和非晶碳（AC）弹性性能的影响。在密度（1.27 g/cm3至2.93 g/cm3）和孔隙率范围内，将原始AC和CF的生成、结构表征和负载与它们的点蚀对应物进行了比较。结果表明，AC的弹性模量降低了18.7%，CF的弹性模量降低了13.7%。我们还观察到AC在氧化和原始状态下的拉伸行为都较弱，这支持了FiberForm可能在粘合剂处失效的假设。本研究促进了对碳基TPS材料氧化与力学行为耦合的基本理解，并为更大规模的模拟奠定了基础。

Opening a band gap in graphene is essential for its integration into electronic devices, but remains a major challenge. Hydrogenation offers a promising route, though the process is complicated by competing mechanisms such as hydrogen desorption and unwanted etching. Here, we investigate one-sided hydrogenation of monolayer graphene on SiO₂/Si substrates at temperatures below ∼100 °C, using a hot-filament-assisted method compatible with semiconductor processing. Our results reveal a regime where hydrogen chemisorption and hole formation (etching) coexist. Dehydrogenation experiments and first-principles calculations indicate that hydrogen atoms preferentially cluster on neighboring carbon sites, potentially leading to dome-like lattice distortions. While hydrogen incorporation is favored at these sites, our simulations suggest that the resulting stresses alone are insufficient to cause carbon–carbon bond breakage. Instead, etching likely requires the presence of energetic atomic hydrogen. These findings help clarify the interplay between hydrogenation and etching and provide guidance for controlled graphene functionalization in device applications.

打开石墨烯的带隙对其集成到电子设备中至关重要，但仍然是一个主要挑战。氢化提供了一条很有前途的途径，尽管这一过程由于氢的解吸和不必要的蚀刻等相互竞争的机制而变得复杂。在这里，我们研究了在温度低于~ 100°C的sio2 /Si衬底上单层石墨烯的单侧氢化，使用与半导体加工兼容的热丝辅助方法。我们的结果揭示了氢化学吸附和空穴形成（蚀刻）共存的机制。脱氢实验和第一性原理计算表明，氢原子优先聚集在邻近的碳位上，可能导致圆顶状的晶格扭曲。虽然氢在这些位置的结合是有利的，但我们的模拟表明，仅产生的应力不足以导致碳-碳键断裂。相反，蚀刻可能需要高能氢原子的存在。这些发现有助于澄清氢化和蚀刻之间的相互作用，并为在器件应用中控制石墨烯功能化提供指导。

MXenes have emerged as promising two-dimensional (2D) materials for catalytic applications in energy production due to their exceptional structural, electronic, and chemical properties. Their high surface area, tunable surface terminations, and excellent electrical conductivity make them ideal candidates for facilitating surface reactions and enhancing charge transfer processes. Additionally, the ability to modify their composition and structure at the atomic level allows for the design of tailored MXene-based catalysts suited for various energy-related reactions. This review highlights recent advancements in MXene-based catalysts, focusing on novel synthesis techniques, including selective etching, CVD and ALD, as well as advanced characterization methods such as XRD, Raman spectroscopy, TEM, FTIR, and In-situ/Operando techniques. Their applications in key catalytic processes, including the Fischer-Tropsch synthesis of hydrocarbons, CO₂ hydrogenation to methane, and hydrogen production via electrochemical water splitting, are discussed, as these reactions play a crucial role in carbon utilization, energy storage, and the transition to sustainable fuels. Notably, Mo₂C-based catalysts favor heavier hydrocarbon formation, while NiV oxycarbide electrocatalysts exhibit high durability and hydrogen selectivity. These findings emphasize MXenes’ potential in sustainable energy conversion and highlight the need for further optimization to enhance their catalytic efficiency and stability.

由于其特殊的结构、电子和化学性质，MXenes已成为在能源生产中催化应用的有前途的二维（2D）材料。它们的高表面积，可调的表面末端和优异的导电性使它们成为促进表面反应和增强电荷转移过程的理想候选者。此外，在原子水平上修改其组成和结构的能力允许设计适合各种能量相关反应的基于mxene的催化剂。本文综述了mxene基催化剂的最新进展，重点介绍了新的合成技术，包括选择性蚀刻、CVD和ALD，以及先进的表征方法，如XRD、拉曼光谱、TEM、FTIR和原位/Operando技术。讨论了它们在关键催化过程中的应用，包括碳氢化合物的费托合成，CO 2加氢制甲烷和通过电化学水分解制氢，因为这些反应在碳利用，能量储存和向可持续燃料过渡中起着至关重要的作用。值得注意的是，Mo₂c基催化剂有利于形成较重的碳氢化合物，而NiV型碳化氧电催化剂具有较高的耐久性和氢选择性。这些发现强调了MXenes在可持续能源转化方面的潜力，并强调了进一步优化以提高其催化效率和稳定性的必要性。

Thin films of grafted pectin were prepared by incorporating thiourea into its structure, using epichlorohydrin as a cross-linker agent. In addition, silver nanoparticles were embedded in the polymer matrix. The changes in the chemical and structural properties of modified pectin were evidenced by FT-IR spectroscopy, XRD, and X-ray Photoelectron Spectroscopy (XPS), while its morphological properties of silver nanoparticles were evaluated by STEM and DLS. Such structural and morphological characterization, along with the optical properties determined by UV–Vis spectroscopy, confirmed the incorporation of silver nanoparticles in the pectin films. The XRD study indicates that the grafting of thiourea onto pectin reinforces its structure, which is reflected in the alteration of the resulting polymer’s amorphousness by hindering the relaxation of its structure; this change is responsible for the decrease in conductivity observed by EIS. The ionic conductivity and band gap energy were estimated by Tauc plot using the UV–Vis Diffuse Reflectance measurements. The remarkably different electrical behavior, diffuse reflectance, and electrochemical impedance (EIS) exhibited by the nanocomposite compared to pristine pectin are consistent with the observed structural changes. Due to a potential conductive network that facilitates ion movement, adding silver nanoparticles (AgNPs) to the pectin matrix improves ionic conductivity and influences the optical band gap.

以环氧氯丙烷为交联剂，在其结构中加入硫脲，制备了接枝果胶薄膜。此外，银纳米颗粒被嵌入到聚合物基体中。利用FT-IR、XRD和x射线光电子能谱（XPS）分析了改性果胶的化学和结构性质的变化，并利用STEM和DLS分析了改性果胶纳米银的形貌特征。这种结构和形态表征，以及通过紫外可见光谱测定的光学性质，证实了银纳米颗粒在果胶薄膜中的掺入。XRD研究表明，硫脲接枝到果胶上增强了其结构，这反映在聚合物的非晶性的改变上，阻碍了其结构的松弛；这种变化是EIS观察到的电导率下降的原因。利用紫外-可见漫反射测量，用tac图估计了离子电导率和带隙能。与原始果胶相比，纳米复合材料表现出的电学行为、漫反射和电化学阻抗（EIS）显著不同，这与观察到的结构变化一致。由于一个潜在的导电网络，促进离子运动，添加银纳米粒子（AgNPs）到果胶基质提高离子电导率和影响光学带隙。

Sodium intercalation in graphite is known to be unstable, posing a challenge for energy storage applications based on this cation. This study combines Raman spectroscopy with first-principles calculations, including electron-phonon coupling, to investigate charge transfer mechanisms and stability in Na-intercalated graphite. Contrary to theoretical predictions on a pure Na graphite intercalated compound, Raman data show no evidence of so-called mechanical coupling between Na⁺ ions and graphene layers. As we have selected a partially graphitized carbon with an intense 2D band for the anode, analyzing the Raman shifts of both the G and 2D bands is possible and allows us to discriminate between doping and lattice expansion treated as strain effects.

钠嵌入石墨是不稳定的，这对基于这种阳离子的储能应用提出了挑战。本研究将拉曼光谱与第一性原理计算相结合，包括电子-声子耦合，研究na插层石墨中的电荷转移机制和稳定性。与纯钠石墨插层化合物的理论预测相反，拉曼数据显示没有证据表明钠离子和石墨烯层之间存在所谓的机械耦合。由于我们选择了具有强烈二维能带的部分石墨化碳作为阳极，因此可以分析G和2D能带的拉曼位移，并使我们能够区分掺杂和晶格膨胀作为应变效应。观察到的位移完全可以用一个简单的电荷转移机制来解释。在第一阶段插入时，每个碳原子的电荷转移值为-0.17±0.02 |e-|。这些发现突出了拉曼光谱量化电荷转移和区分各种碱金属之间插层行为的能力。

The increasing growth of electric vehicles and portable electronics has led to a surplus energy demand in recent decades. Lithium-sulfur (Li-S) batteries have garnered significant attention and are believed to be the most promising future for sustainable high energy supply. Despite their high theoretical capacity, polysulfide shuttling has been a thorny drawback for their experimental performance degradation. In this work, lichen (Parmotrema stuppeum), a unique species with a mutualistic symbiotic relationship with fungi and algae, was used as a biomass for carbon precursor to modify the glass fiber (GF) separator. The necessary 3-dimensional porous carbon structure and active surface functional groups are obtained without extra additives. The porous network associated with l-600 accompanies foam-like structures that are anticipated to filter up polysulfides and facilitate lithium ions transport in the electrode-electrolyte interface. Thereby, the porous architecture ensures physical sites and traps dissolved polysulfide intermediate compounds, holding them as potential active materials that can undergo catalytic reactions within the cathode side. The Li-S cell, accompanied by the modified separator (L-600), offered a high initial specific capacity of 1330 mAh g^-1 at 0.2 C. Further, the Li-S cell offered a prolonged reversible capacity of 725 mAh g^-1 after 200 cycles, with a capacity degradation rate of 0.22 % per cycle. Post-stability analysis of the Li-S separator confirms the effectiveness of the modified separator in mitigating polysulfide shuttling.

近几十年来，电动汽车和便携式电子产品的日益增长导致了能源需求过剩。锂硫（li -硫）电池已经引起了人们的广泛关注，被认为是未来可持续高能量供应最有希望的电池。尽管多硫化物的理论容量很高，但其实验性能的下降一直是一个棘手的缺点。本文以地衣（Parmotrema stuppeum）这种与真菌和藻类共生的独特物种为原料，制备碳前体，用于改性玻璃纤维（GF）分离器。无需额外添加剂即可获得所需的三维多孔碳结构和活性表面官能团。与l-600相关的多孔网络伴随着泡沫状结构，有望过滤多硫化物并促进锂离子在电极-电解质界面中的传输。因此，多孔结构确保了物理位置和捕获溶解的多硫化物中间化合物，使它们成为可以在阴极侧进行催化反应的潜在活性物质。该锂- s电池配有改进的分离器（L-600），在0.2℃下可提供1330 mAh g-1的高初始比容量，并且在200次循环后可提供725 mAh g-1的长期可逆容量，每次循环的容量衰减率为0.22%。对锂硫分离器的后稳定性分析证实了改性后的锂硫分离器在减少多硫化物穿梭方面的有效性。
