Explaining the spread in measurement of PDMS elastic properties: influence of test method and curing protocol by Varner, Hannah, Cohen, Tal

“…Polydimethylsiloxane (PDMS), commonly obtained from Dow as SYLGARD 184, is a ubiquitous such material, which has been integral to the rapid development of biocompatible microfluidic devices and flexible electronics in recent decades. However, reported shear moduli of this material range over 2 orders of magnitude for similar chemical compositions. …”

Carbene-based bioadhesive blended with amine, thiol, and acrylate liquid additives by Ellis, Elizabeth, Djordjevic, Ivan, Muhammad Naziruddin Bin Mohd Ali, Steele, Terry W. J.

“…This work investigates carbene based bioadhesives in the presence of various liquid additives containing reactive functional groups of hydroxyl, thiol, amine, or acrylate. Steady shear viscosity, dynamic mechanical properties, microstructure, and reactive functional groups are evaluated by photorheometry, scanning electron microscopy (SEM), and FTIR spectroscopy. …”

Remarkably enhanced thermal transport based on a flexible horizontally-aligned carbon nanotube array film by Qiu, Lin, Wang, Xiaotian, Su, Guoping, Tang, Dawei, Zheng, Xinghua, Zhu, Jie, Wang, Zhiguo, Norris, Pamela M., Bradford, Philip D., Zhu, Yuntian

“…Here we report a simultaneous sevenfold increase in in-plane thermal conductivity and a fourfold reduction in the thermal contact resistance at the flexible CNT-SiO2 coated heat sink interface by coupling the CNTs with orderly physical overlapping along the horizontal direction through an engineering approach (shear pressing). The removal of empty space rapidly increases the density of transport channels, and the replacement of the fine CNT tips with their cylindrical surface insures intimate contact at CNT-SiO2 interface. …”

Long-term slip rate of the southern San Andreas Fault from 10Be-26Al surface exposure dating of an offset alluvial fan by Ryerson, Frederick J., Van der Woerd, Jérôme, Klinger, Yann, Sieh, Kerry, Tapponnier, Paul, Mériaux, Anne-Sophie

“…This result puts new constraints on the slip rate of the San Jacinto and on the Eastern California Shear Zone for the last 35 kyr. Our study shows that more sites along the major faults of southern California need to be targeted to better constrain the slip rates over different timescales.…”

Phase Change Dispersion Made by Condensation–Emulsification by Fischer, Ludger J., Dhulipala, Somayajulu, Varanasi, Kripa K.

“…They are manufactured by high shear equipment like rotor-stator systems. A recently published method to produce emulsions by the direct condensation of the dispersed phase into the emulsifier-containing continuous phase is applied on this PCD. n-Decane is used as PCM, and the melting temperature is -30 °C. …”

The Influence of Root Geometry on Soil Cohesion and Anchoring Ability through Geologic Time by Colicci, Vittorio

“…Force laws were then derived to approximate the anchoring contributions of root weight, sediment weight, static friction, and shear strength. This analysis revealed a strong dependence on the span, surface area, and volume of the root system, which were used to normalize values across different geometries. …”

Turbulent Flow over a Flexible Wall Undergoing a Streamwise Traveling Wavy Motion by Shen, Lian, Zhang, Xiang, Yue, Dick K.P., Triantafyllou, Michael S.

“…Above a threshold value of c/U ≈ 1, separation is eliminated; and, relative to small- c/U cases, turbulence intensity and turbulent shear stress are reduced significantly. The drag force decreases monotonically as c/U increases while the power required for the transverse motion generally increases for large c/U; the net power input is found to reach a minimum at c/U ≈ 1.2 (for fixed U). …”

Solder joint testing and failure analysis by Kang, Eng Tat.

“…Adhesively bonded joints within most electronic devices are constantly subjected to a complex combination of tensile-shear loading. These devices are also likely to undergo thermo-mechanical cycling during device processing and service and therefore, the joints are likely to have existing low-cycle fatigue cracks, which might adversely affect the joint mechanical integrity under various loading situations. …”
