Study of the zero shear viscosity of SBS copolymer modified bitumens
Budownictwo i Architektura, 2014 The paper presents the results of the zero shear viscosity (ZSV) determined by using a dynamic shear rheometer (DSR). The tests were conducted with the use of 50/70 penetration grade bitumen produced from Venezuelan and Russian crude oils (named V50/70 ...

Advanced Materials, EarlyView.We developed a bioinspired mechano‐intelligent Janus bandage (MIB) with a hydrophobic flat exterior and a hydrophilic interior featuring gecko‐mimicking wedged microstructures, fabricated via micromolding and anisotropic plasma treatment. The MIB dynamically synchronizes adhesion and contraction, enabling precise force modulation.
