Highly-Efficient Charge Separation and Polaron Delocalization in Polymer-Fullerene Bulk-Heterojunctions: A Comparative Multi-Frequency EPR & DFT Study

open access: yes, 2013
The ongoing depletion of fossil fuels has led to an intensive search for additional renewable energy sources. Solar-based technologies could provide sufficient energy to satisfy the global economic demands in the near future.

A Review on Applications and Challenges of Fullerenes in Proton Exchange Membranes

open access: yesCarbon Energy, Volume 8, Issue 2, February 2026.
This review is devoted to the analysis of the use of fullerenes and their functionalized derivatives to improve the efficiency of proton exchange membranes. The synthetic methods, structure, properties, and proton transfer mechanisms of fullerene‐containing membranes are discussed in detail. Promising areas of scientific research are discussed, and key

Polyradical character and spin frustration in fullerene molecules: An ab initio non-collinear Hartree--Fock study

open access: yes, 2014
Most {\em ab initio} calculations on fullerene molecules have been carried out based on the paradigm of the H\"uckel model. This is consistent with the restricted nature of the independent-particle model underlying such calculations, even in single ...

Decoherence in a Two Slit Diffraction Experiment with Massive Particles [PDF]

open access: yes, 2007
Matter-wave interferometry has been largely studied in the last few years. Usually, the main problem in the analysis of the diffraction experiments is to establish the causes for the loss of coherence observed in the interference pattern.

Artemisia selengensis Leaves, a Vegetable Waste: LC‐MS‐Based Chemical Profiling, Ultrasound‐Assisted DES Extraction, and Xanthine Oxidase Inhibitory Activity

open access: yeseFood, Volume 7, Issue 1, February 2026.
This study focused on Artemisia selengensis leaves (ASL), a discarded agricultural waste. 72 compounds were identified by UPLC‐Q‐TOF‐MS. “Green” extraction with DES was optimized, and ASL's XO—inhibition was explored, presenting new ways for waste utilization. ABSTRACT Artemisia selengensis is a medicinal and edible plant, whose tender stems are widely

Decoherence of matter waves by thermal emission of radiation

open access: yes, 2004
Emergent quantum technologies have led to increasing interest in decoherence - the processes that limit the appearance of quantum effects and turn them into classical phenomena.

Carbonisation of biomass-derived chars and the thermal reduction of a graphene oxide sample studied using Raman spectroscopy [PDF]

open access: yes, 2013
Chars and carbonised chars were produced from three different oxygen-rich precursors (Pinus radiata wood, Phormium tenax leaf fibres, and sucrose crystals).

Pressure induced dimerisation of C70

open access: yesSolid State Communications, 1997
Solid C70 has been subjected simultaneously to high pressures and temperatures (HPHT), with pressures upto 7.5 GPa and temperatures upto 750°C. X-ray diffraction measurements on the recovered samples indicate that the initial h.c.p. solid C70 transforms to a rhombohedral structure which recovers to an f.c.c. structure on annealing.

Spheroidal geometry approach to fullerene molecules

open access: yes, 2007
Graphite is an example of a layered material that can be bent to form fullerenes which promise important applications in electronic nanodevices. The spheroidal geometry of a slightly elliptically deformed sphere was used as a possible approach to ...

as-Indaceno[3,2,1,8,7,6-ghijklm]terrylene as a near-infrared absorbing C70-fragment

open access: yesNature Communications, 2020
The synthesis of hydrocarbons with attractive electronic structures remains challenging. Here, the authors describe the synthesis and properties of the C70 fragment as-indaceno[3,2,1,8,7,6-ghijklm]terrylene, which exhibits near-infrared (NIR) absorption.
