Dynamic phototuning of 3D hydrogel stiffness [PDF]
Proceedings of the National Academy of Sciences, 2015 Significance Extracellular matrix (ECM) stiffness is an influential factor in many biological processes. Temporal changes in ECM stiffness are observed in cancer, cardiovascular disease, and wound healing, and are likely involved in disease progression.

Influence of different loads on the properties of lightweight composite
Journal of Civil Engineering and Management, 2012 The paper describes the study on the operational properties of lightweight composite with density of 150–350 kg/m3. It was established that these properties depend on the ratio of porous cement matrix and inclusions of crushed expanded polystyrene ...
