Polyethylene Glycol 20k. Does It Fluoresce?Mon Aug 21 2023
Polyethylene glycol (PEG) is a polyether compound commonly used in biological research and medicine because it is biologically inert. *
This simple polymer exists in variable chain lengths (and molecular weights). As they are devoid of any contiguous π-system, PEGs are expected to lack fluorescence properties. However, recent studies suggested the occurrence of fluorescence properties in non-traditional fluorophores like PEGs. *
In the article “Polyethylene Glycol 20k. Does It Fluoresce?” Bethany F. Laatsch, Michael Brandt, Brianna Finke, Carl J. Fossum, Miles J. Wackett, Harrison R. Lowater, Alex Narkiewicz-Jodko, Christine N. Le, Thao Yang, Elizabeth M. Glogowski, Scott C. Bailey-Hartsel, Sudeep Bhattacharyya and Sanchita Hati report a comprehensive investigation of the molecular basis of the fluorescent properties of PEG 20k molecules using combined experimental and computational methods. Fluorescence measurements of PEG 20k were conducted in aqueous solutions as well as in the presence of metal ions. *

A transversal approach to predict surface charge compensation in piezoelectric force microscopyMon Aug 14 2023
In the field of modern information storage, the physical properties could act as the storage “medium”, such as electric polarization (dipole orientation) of ferroelectric materials, or spin polarization (magnetic vector) of magnetic materials. *
Multiferroic materials have great potential in non-volatile devices for low-power and ultra-high density information storage, owing to their unique characteristic of coexisting ferroelectric and ferromagnetic orders.

Strong, tough, rapid-recovery, and fatigue-resistant hydrogels made of picot peptide fibresThu Jul 27 2023
Hydrogels are promising soft materials as tissue engineering scaffolds, stretchable sensors, and soft robotics. *
Yet, it remains challenging to develop synthetic hydrogels with mechanical stability and durability similar to those of the connective tissues. Many of the necessary mechanical properties, such as high strength, high toughness, rapid recovery, and high fatigue resistance, generally cannot be established together using conventional polymer networks.
Detecting Early-Stage Cohesion Due to Calcium Silicate Hydration with Rheology and Surface Force ApparatusWed Jul 19 2023
Extremely robust cohesion triggered by calcium silicate hydrate (C–S–H) precipitation during cement hardening makes concrete one of the most commonly used man-made materials. *
In the article “Detecting Early-Stage Cohesion Due to Calcium Silicate Hydration with Rheology and Surface Force Apparatus” Teresa Liberto, Andreas Nenning, Maurizio Bellotto, Maria Chiara Dalconi, Dominik Dworschak, Lukas Kalchgruber, Agathe Robisson, Markus Valtiner and Joanna Dziadkowiec present a proof-of-concept study, in which they seek an additional nanoscale understanding of early-stage cohesive forces acting between hydrating model tricalcium silicate (C3S) surfaces by combining rheological and surface force measurements.
