Peri-annulation is recognized as an influential structural motif in accessing functional molecular materials. However, efficient synthetic access to peri-annulated structures remains challenging. Herein, we show that mechanochemistry is a valuable synthetic tool to achieve this goal. It is comparatively better than activation through microwave irradiation and conventional solution-phase reactions. The synthesized materials are molecularly curved nanographenes containing sulfur and selenium atoms. The curvature comes from the use of corannulene as the central building block, upon which the benzothiophene or benzoselenophene are peri-annulated through the palladium-catalyzed direct arylation reactions. Peri-annulation endows the nanographene structures with better optical properties as compared to other annulation chemistries.

In this paper, the mechanical response of a one-dimensional (1D) hexagonal piezoelectric quasicrystal (PQc) thin film is analyzed under electric and temperature loads. Based on the Euler-Bernoulli beam theory, a theoretical model is proposed, resulting in coupled governing integral equations that account for interfacial normal and shear stresses. To numerically solve these integral equations, an expansion method using orthogonal chebyshev polynomials is employed. The results provide insights into the interfacial stresses, axial force, as well as axial and vertical deformations of the PQc ***, fracture criteria, including stress intensity factors, mode angles, and the Jintegral, are evaluated. The solution is compared with the membrane theory, neglecting the normal stress and bending deformation. Finally, the effects of stiffness and aspect ratio on the PQc film are thoroughly discussed. This study serves as a valuable guide for controlling the mechanical response and conducting safety assessments of PQc film systems.

A chance-constrained energy dispatch model based on the distributed stochastic model predictive control (DSMPc) approach for an islanded multi-microgrid system is proposed. An ambiguity set considering the inherent uncertainties of renewable energy sources (RESs) is constructed without requiring the full distribution knowledge of the uncertainties. The power balance chance constraint is reformulated within the framework of the distributionally robust optimization (DRO) approach. With the exchange of information and energy flow, each microgrid can achieve its local supply-demand ***, the closed-loop stability and recursive feasibility of the proposed algorithm are proved. The comparative results with other DSMPc methods show that a trade-off between robustness and economy can be achieved.
