The hierarchical honeycomb structure under impact loading with a velocity of 4.4 m/s and a weight of 261.1 kg showed a maximum energy absorption of 35 J/g, which was significantly higher than the traditional metallic honeycomb structure.
The advanced honeycomb designs, including hierarchical, functionally gradient and sandwich structures, were found to increase the energy-absorbing capabilities of the conventional honeycomb structures by reviewing several research papers in the literature.
Ufodike et al. have designed a functionally-graded honeycomb structure which was inspired by bamboo microstructure. The in-plane compression loading with a loading rate of 5 mm/min on the structure together showed a four times impact energy absorption than that of the graded honeycomb structure.
Additionally, energy absorption capability was accurately predicted for different biaxiality. Conventional honeycomb structures have been extensively used as energy absorbers because of their low cost, simple structural configuration as well as ease of processing. Nonetheless, they showed poor energy absorption characteristics.
Parametric studies found that the graded honeycomb has superior energy absorption capacity. Through multi-objective optimization, the energy absorption could be further increased by up to 89.73%.
Under out-of-plane load, honeycomb absorbs energy through cell wall buckling and membrane deformation. Compared with in-plane load, it usually produces higher peak force, compressive stress and energy absorption level. On the other hand, out-of-plane response will lose metamaterial properties.

Nowadays, one of the major problems in solar energy applications is the storage of the thermal energy. The energy demand has a continue variation while the thermal energy is depending on the wheather, therefore a buffer system that allows to charge or discharge itself in base of the evolution of demand is required in order to avoid the waste of the excess energy.
In the present work, we explore possible topological properties in honeycomb lattice by introducing a texture in hopping energy between nearest-neighboring (NN) sites.

In frustrated spin systems, the arrangement of the particles and the nature of their interactions can lead to frustrations, which is a phenomenon where the system cannot simultaneously satisfy all of its interactions [1]. This can result in a highly degenerate ground state, where many different spin configurations have the same low energy.

Resources are limited and the simple act of retaining them requires resources, especially energy. Living systems must constantly balance the value of resources obtained with the costs of resources expended; failure to do so can result in death or prevent reproduction. Living systems therefore optimize, rather than maximize, resource use.
