“…In both cases, calcinated Si-Zr glass micro-structures excel in LIDT, by potentially having better heat transfer characteristics (SiO2-ZrO2 composites [39] 1 to 3 W/m*K). Also, the minimum bond energy for Si-O (89 kcal/mol) bond in glass is higher than for C-C (80 kcal/mol) or C-O (79 kcal/mol) bonds that constitute the weaker link [40].…”

Laser Direct Writing (LDW), also known as 3D multi-photon laser lithography of resins, is a promising technique for fabricating complex free-form elements, including micro-optical functional components. Regular organic or hybrid (organic-inorganic) resins are often used, with latter exhibiting better optical characteristics, as well as having the option to be heat-treated into inorganic glass-like structures, particularly useful for resilient micro-optics. While this work is a continuation of SZ2080™ calcination development , the Laser-Induced Damage Threshold (LIDT) of such sol-gel-derived glass micro-structures, particularly those that undergo heat treatment, has not been well-characterized. In this pilot study, we investigated the LIDT using the Series-on-One (S-on-1) protocol of functional micro-lenses produced via LDW and subsequently calcinated. Our results demonstrate that the LIDT can be significantly increased, even multiple times, by this approach, thus enhancing the resilience and usefulness of these free-form micro-optics. This work represents the first investigation in terms of LIDT into the impact of calcination on LDW produced sol-gel-derived glass micro-structures, and provides important insights for the development of robust micro-optical devices.

We have designed possible structures of the isomers of midi-fullerenes, namely C40, C42, C44, C46, and C48; three the most natural mechanisms of their formation being used: fusion of carbon cupolas having the same symmetry; fusion of fullerenes having compatible symmetry and embedding carbon dimers into initial fullerenes. The energies of the fullerenes calculated through the use of molecular mechanics are presented together with their graphs. It is found that in the majority of cases the minimum-energy fullerenes are those, which have tetrahedral symmetries. The maximum-energy fullerenes refer to the three-fold T-symmetry.
