Correlation of processing, morphology and mechanical behavior - Our recent publication analyzes this topic in depth for injection molded Polyoxymethylene (POM): https://lnkd.in/d37nPwuM Such data is hard to find for engineering polymers, making us even prouder of the final result. It is the second paper out of an intended trilogy. Part 3 focusing on harsher conditions is (hopefully) coming soon... 🙂

Congratulations CNM staff and users! In a recent Nature Sustainability publication, researchers have manipulated the chemical composition of materials to make polymers more recyclable. The team developed a strategy to design biodegradable and recyclable luminescent polymers with high light-emitting efficiencies. They did so by incorporating a chemical called tert-butyl ester into the luminescent polymers which can break down when exposed to heat or mild acid. Check out this Argonne Press Release for more information: https://lnkd.in/gbSVDTh2   #nanoscience #materialsscience      Authors: Wei Liu, Yukun Wu, Katerina Vriza, Cheng Zhang, Hyocheol Jung, Shiyu Hu, Yuepeng Zhang, Du Chen, Peijun Guo, Benjamin T.

Our research on "Aqueous Electrochromic Batteries" has been published in American Chemical Society ACS Applied Materials & Interfaces! Check out the full article here: https://lnkd.in/gyH7j3rR. In this study, we explored the potential of aqueous electrochromic batteries (ECBs) for renewable rechargeable technology. Our findings reveal that Jahn–Teller distortion induced by interlayer water serves as an excellent ion host for zinc-ion aqueous electrolyte ECBs. This results in superior redox reactivity, optical modulation, capacity, and cyclic stability compared to AWO. Special thanks to the Department of Science and Technology India (DST) India DST for their support through the "Advanced Materials Technology (AMT)" Project, aimed at developing Affordable Electrochromic Windows.

#Review Nanomaterials-Based Ion-Imprinted Electrochemical Sensors for Heavy Metal Ions Detection: A Review by Liangyun Yu, Liangju Sun, Qi Zhang, Yawen Zhou, Jingjing Zhang, Bairen Yang, Baocai Xu and Qin Xu https://lnkd.in/eMvkCnxr MDPI Yangzhou University Yancheng Institute of Technology #electrochemicalsensors #heavymetalions #molecularimprinting #ionimprinting #nanomaterials #openaccess #Abstract Heavy metal ions (HMIs) pose a serious threat to the environment and human body because they are toxic and non-biodegradable and widely exist in environmental ecosystems. It is necessary to develop a rapid, sensitive and convenient method for HMIs detection to provide a strong guarantee for ecology and human health. Ion-imprinted electrochemical sensors (IIECSs) based on nanomaterials have been regarded as an excellent technology because of the good selectivity, the advantages of fast detection speed, low cost, and portability. Electrode surfaces modified with nanomaterials can obtain excellent nano-effects, such as size effect, macroscopic quantum tunneling effect and surface effect, which greatly improve its surface area and conductivity, so as to improve the detection sensitivity and reduce the detection limit of the sensor. Hence, the present review focused on the fundamentals and the synthetic strategies of ion-imprinted polymers (IIPs) and IIECSs for HMIs detection, as well as the applications of various nanomaterials as modifiers and sensitizers in the construction of HMIIECSs and the influence on the sensing performance of the fabricated sensors. Finally, the potential challenges and outlook on the future development of the HMIIECSs technology were also highlighted. By means of the points presented in this review, we hope to provide some help in further developing the preparation methods of high-performance HMIIECSs and expanding their potential applications.

Our study provides crucial insights into optimizing the synthesis of layered oxide cathode materials for lithium-ion batteries using spray pyrolysis. Key innovations: 1. First use of high-temperature X-ray diffraction (HT-XRD) to study structural evolution of spray pyrolysis-synthesized LiCoO2 (LCO), enabling precise optimization of annealing conditions. 2. Direct comparison of nitrate vs acetate precursors, revealing distinct impacts on particle morphology and electrochemical performance. 3. Achieved initial discharge capacities up to 179 mAh/g for nitrate-derived LCO - surpassing many previous reports. Why it matters: Optimizing layered oxide cathode materials is crucial for advancing lithium-ion battery technology. Our findings provide a roadmap for synthesizing high-performance layered oxide cathodes, potentially leading to batteries with improved capacity, efficiency, and durability. This work paves the way for more efficient, high-throughput processes in battery material synthesis - a critical step towards meeting growing energy storage demands.

After a few setbacks not unrelated to getting a lectureship and a global pandemic, the final project I started as a postdoc has now been published! Continued by Xiaoyan Lin, PhD and Yiyan Chen, we show a proof-of-concept for a biomaterial strategy that greatly improves the thermal resistance of nucleic acid therapeutics enabling long-term storage at room temperature (and protection against thermal fluctuations). This could pave the way for eliminating the "cold-chain" for the distribution and storage of advanced medicines, greatly improving accessibility and cost. https://lnkd.in/e_tENiPe

Our latest research, published in JMC-A Royal Society of Chemistry , https://lnkd.in/gzZR4dy3 presents significant progress towards cost-effective electrochromic smart windows! Traditionally, achieving high performance in these windows relied heavily on expensive cathode materials and complex optimization processes. We addressed this by focusing on the anode (NiO), achieving superior results with an ultrathin (50 nm) layer using an industrially scalable sputtering technique. Here's what our research highlights: Ultrathin NiO anode: Delivers over 60% optical modulation with excellent coloration efficiency. Process optimization: Achieved through tailoring oxygen and argon ratios during deposition. Electrolyte exploration: Aqueous LiOH demonstrated superior performance compared to other solutions.
