SIMULATIONS OF THE PROPERTIES OF ELONGATED HEXAGONAL DODECAHEDRON SYSTEMS

open access: yesTASK Quarterly, 2014
This study considers a 3D basic unit-cell proposed for auxetic and non-auxetic foams namely the elongated hexagonal dodecahedron deforming through changes in angle between its ligaments (idealised hinging model). This structure was studied in detail for

SPACETIME FOAM [PDF]

open access: yesInternational Journal of Modern Physics D, 2002
Spacetime is composed of a fluctuating arrangement of bubbles or loops called spacetime foam, or quantum foam. We use the holographic principle to deduce its structure, and show that the result is consistent with gedanken experiments involving spacetime measurements.

Microplastics Increase Soil pH and Decrease Microbial Activities as a Function of Microplastic Shape, Polymer Type, and Exposure Time

open access: yesFrontiers in Environmental Science, 2021
Microplastic pollution is a topic of increasing concern, especially since this issue was first addressed in soils. Results have so far been variable in terms of effects, suggesting that there is substantial context-dependency in microplastic effects in ...
