Summary: The study investigates the synergetic effects in double-wall carbon nanotube (DWCNT) samples through absorption, fluorescence excitation, and resonant Raman scattering spectroscopy. The chirality-dependent shifts of the vibrational frequencies and transition energies of the inner and outer DWCNT walls are determined. The combined analysis of PLE and RRS results provides insights into the energy transfer within DWCNT structures and the specific combinations present in the samples.

Summary: The helicity-dependent Raman spectra of an isolated, chiral, single-wall carbon nanotube were studied using circularly polarized light. It was found that the polarized Raman intensity for the radial breathing mode exhibited an asymmetric angle dependence, reflecting the axial chirality of the nanotube. The complex phase of each component of the Raman tensor reached a maximum at a chiral angle of 15 degrees, which was between two non-chiral nanotubes.

Summary: Surface integration of molecular catalysts inspired by hydrogenase enzymes' active sites offers a promising approach for developing noble metal-free and sustainable H2 production technologies. In this study, a diironhexacarbonyl complex with two pyrene groups per catalytic unit was prepared and electrochemically characterized, allowing for its smooth integration onto multiwalled carbon nanotube-based electrodes through pi-interactions. The grafted catalyst achieved turnover numbers for H2 production of up to 4 +/- 2x10(3) within 20 hours of bulk electrolysis at neutral pH.

Summary: The study investigates the thermoelectric properties and phonon puddles in the charge density wave states in 1T-TaS2 using scanning thermoelectric microscopy. The authors observe counterintuitive variations in thermopower at the atomic scale due to the localization of valence electrons and their interlayer coupling. They also discover phonon puddles with a spatial range shorter than the conventional mean free path, revealing phonon propagation and scattering in the subsurface structures of 1T-TaS2.

Summary: The efficiency and compactness of conventional thermoelectric generators (TEGs) are hindered by their low efficiency and costly composition. A proposed solution is the PN-junction-based TEG, but the efficiency is severely reduced due to recombination at the junction. In this study, we propose a nanoscale homojunction thermoelectric generator by engineering the MoS2 grain boundary and demonstrate that localized defect states enable exceptional integration density and efficiency by barricading recombination at the junction. Our findings suggest that structural defects could pave the way for productive thermoelectric energy recycling at the nanoscale.

Electronic ratchets, such as conjugated polymer-based and semiconducting single-walled carbon nanotube (s-SWCNT) channels, have been proposed as solutions to convert AC signals or electronic noise into stable DC power. These s-SWCNT electronic ratchets demonstrate higher output power and improved stability compared to polymer-based analogs, showing promise as energy harvesting devices for portable, low-power applications.
