Summary: The unique electronic and vibrational properties of linear carbon chains (LCCs) have attracted attention recently. Raman spectroscopy has been widely used to identify LCC and study its properties. This study investigates the optical resonance window of LCCs encapsulated by multi-walled carbon nanotubes (MWCNTs) and a Raman signature assigned to the LCC's longitudinal acoustic phonon mode. First-principles calculations support the conclusions.

Summary: In this paper, high-pressure Raman experiments were conducted on linear carbon chains encapsulated by multi-walled and double-walled carbon nanotubes. The experiments revealed the softening and disappearance of carbon chain modes under high pressure, which were attributed to chain coalescence and tube-chain cross-linking. Computational simulations supported the experimental observations and suggested the possibility of obtaining special structures of carbon chains and composites under high pressure.

Summary: In this study, anti-Stokes Raman scattering of single carbyne chains confined inside double-walled carbon nanotubes was investigated using tip-enhanced Raman scattering (TERS). The temperature dependence of carbyne's Raman spectrum was studied and laser-induced heating was quantified based on the anti-Stokes/Stokes ratio. Due to its molecular size and large Raman cross section, carbyne shows great promise for local temperature monitoring and potential applications in nanoelectronics and biology.

Summary: In this study, the synthesis of linear carbon chains (LCCs) in carbon nanotubes under different pressures was investigated, revealing that pressure indeed plays a role in tuning the yield of LCCs. Lower pressure was found to result in smaller activation energy, making it easier to synthesize LCCs in better vacuum conditions. Additionally, it was demonstrated that low vacuum pressures around 10-3 to 10-1 Pa are sufficient for practical large-scale synthesis and applications of LCCs.

Summary: In this paper, passivated ultrathin Cu (In1-xGax)Se2 solar cells with different bandgap grading configurations were physically modeled. The impact of absorber doping density, electron affinity, and operating temperature on device performance was observed. ZnS was used as a buffer layer to replace CdS and improve cell efficiency. Simulation results showed that a high bandgap at the front and rear sides with an acceptor density of 2 x 10^(16) provided the best electrical cell parameters: J(sc) of 31.53 mA/cm^2, V-oc of 742.78 mV, FF of 77.50%, eta of 18.15%. These findings can guide the optimization of new single and/or tandem cells for high efficiency.

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.

Summary: This study demonstrates the improvement of mechanical properties and reduction of coefficient of thermal expansion (CTE) in graphene oxide (GO)/epoxy (EP) nanocomposites by enhancing the interface between GO and EP through functionalization and incorporating rigid-flexible interphases. The results reveal that the SiO2-PEA-GO hybrid exhibits better strengthening and toughening effects, as well as lower CTE, compared to the PEA-GO hybrid due to the presence of rigid-flexible interfaces with higher bonding strength and better energy dissipation mechanisms. Additionally, the nanocomposites with longer polyetheramine (PEA) molecules in the rigid-flexible interphases demonstrate higher strength and toughness, while maintaining a lower CTE. This work provides a promising strategy for constructing adjustable flexible-rigid interfacial structures and offers potential in developing GO/EP nanocomposites with high mechanical properties and low CTE.
