Summary: In this study, two trilayer nanographenes were synthesized by covalently linking nanographene layers through helicene bridges, and their compact trilayer-stacked architecture was characterized. By introducing a furan ring into the helicene linker, the interlayer overlap and pi-conjugation of the trilayer nanographenes can be modulated, enabling tunable interlayer coupling. The synthesized trilayer nanographenes exhibit rigid chirality transfer from the helicene moiety to the stacked nanographene layers, representing covalently linked multilayer nanographenes with a tunable multilayer stacking structure.

Summary: This paper investigates the effects of material structures on the anion storage behavior in dual-ion batteries (DIBs) by synthesizing graphite with an ultra-large interlayer distance and heteroatomic doping. The large interlayer distance of 0.51 nm provides more space for anion storage, while the doping of heteroatoms reduces the energy barriers for anion intercalation and migration and enhances rapid ionic storage at interfaces simultaneously. The DIBs composed of carbon cathode and lithium anode achieve an ultra-high capacity of 240 mAh g(-1) at a current density of 100 mA g(-1), while the dual-carbon batteries (DCBs) using graphite as both cathode and anode cycle steadily for 2400 times at a current density of 1 A g(-1).

Summary: This paper investigates the growth of high-purity and high-quality turbostratic graphene with different interlayer spacings by calcining ferric chloride and sucrose at 1000 degrees C under an argon atmosphere. The obtained turbostratic graphene contains two different interlayer spacings: 3.435 and 3.55 & Aring;. The two different interlayer spacings of turbostratic graphene are the result of different cooling rates at higher and lower temperatures.

Summary: In this study, high-purity and high-quality turbostratic graphene with different interlayer spacings were successfully grown by calcining ferric chloride and sucrose at 1000 degrees C for 1 hour under an argon atmosphere. X-ray diffraction patterns and Raman results revealed that the turbostratic graphene consists of two different interlayer spacings: 3.435 and 3.55 angstrom. The two interlayer spacings are formed due to different cooling rates at higher temperature ranges (>700 degrees C) and lower temperatures (<700 degrees C).

Summary: We present a scalable and environmentally friendly gas phase technique using atmospheric pressure electrical spark discharge plasmas to produce Au/Co binaries, an effective catalyst system for decomposing hydrogen-rich compounds. We demonstrate the production of Au/Co alloy nanoparticles using the spark plasma-based technique. We also show the ability to vary the morphology and phase structure of the generated aerosol through real time heat treatment, resulting in Au/Co/CoO particles with continuous control over a wide range of particle composition. These results have important implications for transitioning lab-scale nanocatalyst-based hydrogen storage systems to real-world applications.

Summary: We demonstrate all-round dynamic control of interlayer-excitons and -trions in a WSe2/Mo-0.5 W-0.5 Se-2 heterobilayer using multifunctional tip-enhanced photoluminescence (TEPL) spectroscopy with <20 nm spatial resolution. We show the bandgap tunable interlayer excitons and the dynamic interconversion between interlayer-trions and -excitons through the combinational tip-induced engineering of GPa-scale pressure and plasmonic hot electron injection, with simultaneous spectroscopic TEPL measurements. This unique nano-opto-electro-mechanical control approach provides new strategies for developing versatile nano-excitonic/trionic devices using TMD heterobilayers.

Summary: A combinatorial study using magnetron sputtering system was conducted to find the suitable ternary compositions of ZnO-In2O3-SnO2 (ZITO) thin films for optoelectronic applications. The sputtering gas pressure, deposition time, and substrate temperature were studied as process variables, and their effects on composition, optical, and electrical properties were examined. The results showed that ZITO samples deposited under a sputtering gas pressure of 10 mTorr and deposition time of 45 min in the Zn-rich region exhibited the best optical properties (max. 84%), while In-rich compositions showed better electrical properties (min. 14 & omega;/). The most suitable ZITO composition for various optoelectronic applications was determined to be 61.7 at.% Zn, 31.4 at.% In, and 6.9 at.% Sn. Furthermore, increasing the deposition temperature improved the optoelectronic properties and crystal quality of the thin film samples.

Summary: This paper investigates the friction and wear behaviors of two types of polycrystalline diamonds against different materials. The results show that increasing surface roughness leads to an increase in coefficient of friction. The coefficient of friction and wear rate of ceramic Si3N4 balls are generally lower than those of steel GCr15 balls, except for one type of polycrystalline diamond. Transfer films of SiO2 and its hydrate are observed at the friction interface, which contribute to smoother friction and wear. Carbon-based transfer films are also identified, mainly catalyzed by residual cobalt in the polycrystalline diamonds, leading to a phase transformation.

Summary: A single-beam Z-Scan experiment was conducted to investigate the nonlinear optical absorption and optical limiting properties of Bi2O3, rGO/Bi2O3, Bi2O3/WO3, and rGO/Bi2O3/WO3 nanostructures. The results showed that the synthesized nanostructures exhibited varying levels of nonlinear absorption, with bismuth-based nanostructures showing the lowest optical limiting threshold and a higher two-photon absorption coefficient. The presence of rGO contributed to the extended conjugation for charge transfer, while the strong UV-Visible absorption of Bi2O3 and WO3 led to a unique nonlinear optical response.

Summary: The recent observations of superconductive-ordering in carbon-based systems consisting of rhombohedral stacking-faults, trilayer graphene (ABC-stacks) or dislocation-rich interfaces (pyrolytic graphite) have attracted significant attention. In this study, an unusual nucleation of rhombohedral stacking-faults in low-dimensional systems comprising of multiwall carbon nanotube (CNT) buckypapers was reported. The presence of sulfur doping resulted in a broad-band at the Raman shift from 1800 to 2000 cm(-1), indicating contributions arising from disorder-rich regions with rhombohedral stacking-order (ABC-stacks). These observations were further supported by X-ray diffraction and Rietveld refinements.
