Thermodynamic Scaling of the Viscosity of Van Der Waals, H-Bonded, and Ionic Liquids

open access: yes, 2006
Viscosities and their temperature, T, and volume, V, dependences are reported for 7 molecular liquids and polymers. In combination with literature viscosity data for 5 other liquids, we show that the superpositioning of relaxation times for various glass-

Biodegradable Poly(butylene adipate‐co‐terephthalate)/Poly(lactic) Acid Mulch Film with Soy Waste Filler for Improved Biodegradation and Plant Growth

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
The study finds that mulch films made with poly(butylene adipate‐co‐terephthalate)/poly(lactic acid) and 10% soy waste degrade faster than those without soy. Plants grown with the soy‐containing films are 49% taller, suggesting that the soy acts as a biostimulant.

Electrically Conductive and Recyclable Biocomposite Coatings for Robotic Grippers and Touch Sensors

open access: yesAdvanced Intelligent Systems, EarlyView.
Sustainable robotics can reduce robot environmental impact by optimizing wear‐prone components, such as grippers and touch sensors, with recyclable materials and low‐energy manufacturing. Electrically conductive biocomposite coatings, made from biopolymers and carbon fillers, enable robust piezoresistive and piezocapacitive feedback.

Strain rate effect on the mechanical behaviour of a textile reinforced cement composite [PDF]

open access: yes, 2010
The static tensile behaviour of Textile Reinforced Cement Composites is known and can be modeled adequately. However, using these static material properties under dynamic loadings such as impact and seismic loadings, can cause over- or underestimation of
