Hace 8 horas · They also used LPBF to 3D print honeycombs measuring 2.45mm, and compared these with the structures created using ME. Compressive loading was then applied to the sides of the 3D printed honeycombs at rates ranging from 0.5 mm/min and 600 mm/min. During this testing, the failure modes of the lattices were observed and analyzed using DIC.
Hace 1 día · Ali Hussain. May 13, 2024. As heatwaves become more frequent, bumblebee populations face a critical challenge: their nests can no longer regulate internal temperatures effectively, resulting in losses of larvae. This trend, highlighted by recent research published in Frontiers in Bee Science, underscores the profound impact of global warming on ...

Hace 8 horas · 2.2 Fabrication of aluminum foam-filled honeycombs. Aluminum foam (AF) is characterized by its highly porous structure, which imparts several advantageous properties such as low density, superior EA performance, and high specific stiffness. These remarkable properties make AF an attractive material for applications requiring energy absorption.
Hace 5 días · Stingless bees (SB), sometimes called stingless honey bees or simply meliponines, are a large group of bees (from about 462 to 552 described species), comprising the tribe Meliponini (or subtribe Meliponina according to other authors). They belong in the family Apidae (subfamily Apinae), and are closely related to common honey bees (HB, tribe Apini), orchid bees (tribe Euglossini), and ...
Hace 3 días · In geometry, a convex uniform honeycomb is a uniform tessellation which fills three-dimensional Euclidean space with non-overlapping convex uniform polyhedral cells. Twenty-eight such honeycombs are known: the familiar cubic honeycomb and 7 truncations thereof; the alternated cubic honeycomb and 4 truncations thereof; 10 prismatic forms based ...
