Modeling the relaxation of fluctuations in glass during the Ritland crossover experiment

Collin J. Wilkinson, Kuo-Hao Lee, Danqi Yin, John C. Mauro

Methods to match simulation and experimental work are always valuable. The authors highlight modeling of long-term kinetics and relaxation in glass and glassy materials. Their approach takes account of evolutionary models and fictive temperature behavior, favoring a minimal approach in the number of assumptions while retaining effectiveness.

The effects of temperature, pressure, and time on lignin incorporation in bacterial cellulose materials

Jeremy L. Fredricks, Mallory Parker, Paul Grandgeorge, Andrew M. Jimenez, Esther Law, Marissa Nelsen, Eleftheria Roumeli

Cellulose-based materials have grown in relevance as an alternative to plastics-based materials and manufacturing ecosystems. The authors focus on lignocellulosic papers from bacterial cellulose and their properties as correlated with composition and processing methods. Improvements in thermomechanical properties are emphasized.

Cryogenic electron microscopy for emerging materials research: From quantum materials to energy applications

Kai He

Advanced electron microscopy tools have become paramount to advances in quantum materials, especially with investigations of phenomena in multidimensions. The author summarizes advances in the field, including multimodal and hyphenated methods. The development of quantum materials and their future applications will gain in advances with other spectroscopic-microscopic characterization advances.

Anirbid Sircar, Krishna Solanki, Namrata Bist, Kriti Yadav, Kabyashree Mahanta

The authors critically address the impact of green hydrogen on the environment, as well as the hazards and safety issues. They also discuss the challenges associated with green hydrogen and deliberate on the pillars for developing policies and strategies for green hydrogen in India.

Low-cost fluorinated diatomaceous earth polyurethane foam for the absorption of oil

Helanka J. Perera, Anjali Goyal, Hussaina Banu, Saeed M. Alhassan

The authors present the successful synthesis of surface-modified polyurethane for its suitability for oil absorption capacity in cleaning the oil pollutants from water and for cleanup purposes of organic solvents. Such a high performing hydrophobic and oleophilic polyurethane foam functionalized with diatomaceous earth and fluorosilane are eco-friendly and low-cost materials for their potential use as absorbents for oil.

Perspective: Design of cathode materials for sustainable sodium-ion batteries

Baharak Sayahpour, Hayley Hirsh, Saurabh Parab, Long Hoang Bao Nguyen, Minghao Zhang, Ying Shirley Meng

Open Access

The authors summarize the most important design metrics in sodium-ion batteries with an emphasis on cathode materials and outline a transparent data reporting approach based on common metrics for performance evaluation of future technologies. They highlight that manufacturing sustainable sodium-ion batteries with high energy density and cyclability requires a uniquely tailored technology and close attention to economic and environmental factors.
