Summary: The quality of graphene, obtained through Raman spectroscopy, has been correlated with the structural changes occurring at the graphene/germanium interface during in-vacuum thermal annealing. It was found that graphene becomes significantly defective at 650 degrees C due to the release of trapped H-2 gas. Interestingly, a complete self-healing process was observed in graphene upon annealing at 800 degrees C.

Summary: This study focuses on the evaluation of the influence of chemical treatment on the structure and morphology of carbon phases. The chemical interactions of two types of graphite and carbon black with acetone, toluene, and phenol were studied. Experimental and theoretical methods were used to determine the chemical and phase composition, as well as the morphology and structure. The findings suggest that the treatment of graphite powders and carbon black with acetone, toluene, or phenol can be an effective preliminary stage for their modification and conversion into graphene-like phases.

Summary: In this study, we filled single-walled carbon nanotubes (SWCNTs) with nickelocene molecules and separated them by conductivity type using density-gradient ultracentrifugation. By thermally treating the nickelocene-filled metallic SWCNTs in high vacuum, we were able to tailor their electronic properties. Our findings showed that annealing at different temperatures resulted in either n-doping or p-doping of SWCNTs, with the chemical state of the incorporated substances at different annealing temperatures influencing the electronic properties of SWCNTs.

Summary: Reliable and straightforward characterization and analysis of carbon-based nanomaterials on the atomic level is crucial. Combination of highly surface sensitive x-ray photoelectron (XP) spectroscopy and near edge x-ray absorption fine structure spectroscopy (NEXAFS) is used to study and quantify the covalent functionalization of nanographene and single-walled carbon nanotubes with nitrene [2 + 1]-cycloaddition. The results show preserved n-conjugated system of functionalized carbon-based nanomaterials according to NEXAFS analysis, which is challenging to prove with XP spectroscopy alone. The combination of analytical approaches is suited to study post-modification reactions of functionalized carbon-based nanomaterials.

Summary: Coaxial synthesis of single-walled and multiwalled molybdenum disulfide (MoS2) nanotubes on boron nitride nanotubes (BNNTs) was achieved by removing single-walled carbon nanotubes (SWCNTs) from heteronanotubes. Single-walled MoS2 nanotubes exhibit direct bandgap structure around 6-7 nm diameter, with a transition from indirect to direct gap above 5.2 nm. Presence of SWCNTs in BNNTs and single-walled MoS2 nanotubes significantly quenches the PL signal.

Summary: Sodium-ion batteries have attracted interest as potential replacements for lithium-ion batteries. P2-type layered oxides, such as Na-x TMO2, are promising cathode materials due to their high theoretical capacities and competitive prices. However, these materials are often unstable in air due to their reactivity with water and carbon dioxide. In this study, Na0.67Mn0.9Ni0.1O2 was synthesized using a sol-gel method and exposed to air to transition to a Na-rich birnessite phase. The transition was tracked using XRD and neutron diffraction. The electrochemical performances of the pristine and air-exposed NMNO were comparable, with capacities fading from 140 to 60 mAh g(-1) in around 100 cycles. The structural evolution of the air-exposed NMNO was investigated using ex situ synchrotron XRD and Raman. DFT analysis revealed similar charge compensation mechanisms between P2 and birnessite phases, explaining the similarities in their electrochemical properties.

Summary: Discovering low-cost and earth-abundant electrocatalysts for oxygen reduction reaction (ORR) is crucial for advanced energy conversion technologies. A series of carbon-based ORR electrocatalysts were prepared using a two-step pyrolysis method at 600 and 900 degrees C. Different carbon, nitrogen, and sulphur sources were utilized, along with iron and copper salts, to produce non-noble metal-doped carbons. The materials were characterized extensively, and the best ORR performance was observed in sulphur- and nitrogen-modified carbons with nanotubes, indicating the occurrence of synergistic effects between heteroatoms and nanotubes.
