Deep learning to establish structure property relationships of impact copolymers from AFM phase images

Dalia Yablon, Ishita Chakraborty, Hillary Passino, Krishnan Iyer, Antonios Doufas, Maksim Shivokhin

The use of artificial intelligence and machine learning is becoming prevalent in a number of materials development and analytical methods. In atomic force microscopy imaging, a deep learning model based on a convolutional neural net has been developed for microstructure correlation with various bulk mechanical properties. This should enable higher throughput methods of analysis and interpretation, leading to faster decision-making timelines. https://doi.org/10.1557/s43579-021-00103-2

Cross-linked polyrotaxane to improve mechanical properties of oil well cement

Hasmukh A. Patel, Kenneth D. Johnson, Roland F. Martinez, Peter J. Boul

Materials for the oil and gas industry require higher performance in more extreme environments. The authors highlight the use of cross-linked polyrotaxanes with movable cross-links and slide-ring components to improve the elastic modulus in cements used for downhole applications. New materials properties can be realized once the demand for performance is met by smart polymer additives. https://doi.org/10.1557/s43579-021-00080-6

On the progress of 3D-printed hydrogels for tissue engineering

Rigoberto C. Advincula, John Ryan C. Dizon, Eugene B. Caldona, Robert Andrew Viers, Francis Dave C. Siacor, Reymark D. Maalihan, Alejandro H. Espera Jr.

Open Access

The use of hydrogels in a variety of biomedical applications requires a combination of swellability and biocompatibility matched by function, for example implants, coatings, artificial vessels, etc. In tissue engineering, cell differentiation requires the use of growth factors and biomarkers to establish cell quorum sensing and biointegration. The authors demonstrate that 3D printing can afford scaffold spatiotemporal control through design and biomaterials properties matched by digital manufacturing. https://doi.org/10.1557/s43579-021-00069-1

Integration of energy storage with diesel generation in remote communities

Rodrigo D. Trevizan, Alexander J. Headley, Robert Geer, Stanley Atcitty, Imre Gyuk

Open Access

Battery energy storage may improve energy efficiency and reliability of hybrid energy systems composed of diesel and solar photovoltaic power generators serving isolated communities. The authors highlight how battery energy storage systems can reduce run hours on the remaining generators while providing system redundancy in the event of a generator trip, and provide additional benefits such as reducing fuel consumption and deferring generator overhaul. https://doi.org/10.1557/s43581-021-00013-9

In situ characterizations of photoelectrochemical cells for solar fuels and chemicals

Rambabu Yalavarthi, Olivier Henrotte, Alessandro Minguzzi, Paolo Ghigna, Daniel A. Grave, Alberto Naldoni

The authors review the use of advanced in situ and operando characterizations under working photoelectrochemical (PEC) conditions. Enabling the large-scale development of PEC technology by 2050 will deliver fuels and chemicals having zero (or negative) carbon footprint. The key enabling feature to developing PEC technology is improving the photoelectrode materials that are responsible for the absorption of light and transport of the photogenerated charge carriers to drive electrochemical surface reaction. https://doi.org/10.1557/mre.2020.37

Sustainable design of fully recyclable all solid-state batteries

Darren H.S. Tan, Panpan Xu, Hedi Yang, Min-cheol Kim, Han Nguyen, Erik A. Wu, Jean-Marie Doux, Abhik Banerjee, Ying Shirley Meng, Zheng Chen

With the rapidly increasing ubiquity of lithium-ion batteries, sustainable battery recycling is a matter of growing urgency. The authors demonstrate the first fully recycled all solid-state batteries and provide critical design consideration for future sustainable batteries. A scalable battery recycling strategy to recover and regenerate materials in spent all solid-state batteries will enable the reduction of energy consumption and greenhouse gases. https://doi.org/10.1557/mre.2020.25
