A cilia-inspired micropatterned sensor with a high-permittivity dielectric hydrogel for ultrasensitive mechanoreception both in air and underwater
Yuanyuan Wang,a Jiaqi Liao,a Chencong Liu,a Qingfeng Sun,*a Julia L. Shamshina,*b Xiaoping Shen*a
Hydrogel mechanosensors have garnered increasing attention for their diverse applications in human-machine interfaces, healthcare monitoring, and underwater technologies. However, hydrogel mechanosensors still encounter notable limitations, including relatively low sensitivity, vulnerability to water evaporation in air, and water absorption underwater. Herein, we present an innovative cilia-inspired hybrid mechanosensor capable of intelligent mechanoreception in both terrestrial and aquatic environments. The sensor comprises a cilia-micropatterned hybrid electrode and an amphibiously high-permittivity dielectric hydrogel (30.7-41.1 in the wet state and 17.7-21.0 in the dry state). The hybrid electrode mimics the natural cilia structure, offering exceptional sensitivity (182 kPa-1) and limit of detection (0.18 Pa) even under microstress stimuli. Experimental results demonstrate the sensor's outstanding performance in capturing real-time acoustic waves (1-20 kHz), water waves and respiratory rate underwater as well as stable pressure detection in air, showcasing its applicability in high-performance versatile mechanosensing and ushering in new opportunities for a wide range of applications.

Abstract: There will be common challenges to scaling-up any ionic liquids separations technologies which require very large volumes of ionic liquid. Some of these challenges are illustrated in this personal account which chronicles the extraction of chitin from shrimp shell from discovery to current commercialization efforts. The road being taken from discovery in an academic laboratory, through attempts to navigate the scaling-up to commercial scale using the vehicle of a faculty startup company is rewarding, but fraught with roadblocks, detours, and unexpected challenges. The differences in ‘technically feasible’ and ‘commercially viable’ are not always evident from the beginning of the journey, however, one wonders what achievements we miss as a Society because it was assumed to not be commercially viable.

Journal: Molecules // Section: Molecular Structure // Special Issue: Spectroscopic Analysis and Molecular Modification of NanomaterialsEffect of Microwave Plasma Pre-treatment on Cotton Cellulose Dissolution A Themed Issue Spectroscopic Analysis and Molecular Modification of Nanomaterials Abstract: The utilization of cellulose to its full potential is constrained by its recalcitrance to dissolution resulting from the rigidity of polymeric chains, high crystallinity, high molecular weight, and extensive intra- and intermolecular hydrogen bonding network. Therefore, pretreatment of cellulose is usually considered as a step that can help facilitate its dissolution. We investigated the use of microwave oxygen plasma as a pre-treatment strategy to enhance the dissolution of cotton fibers in aqueous NaOH/Urea solution, which is considered to be a greener solvent system compared to others. Fourier Transform Infrared spectroscopy, Scanning Electron Microscopy, and Powder X-ray diffraction analyses revealed that plasma pretreatment of cotton cellulose leads to physicochemical changes of cotton fibers. Pretreatment of cotton cellulose with oxygen plasma for 20 and 40 min resulted in the reduction of the molecular weight of cellulose by 36% and 60% and crystallinity by 16% and 25%, respectively. This reduction in molecular weight and crystallinity led to a 34% and 68% increase in the dissolution of 1% (w/v) cotton cellulose in NaOH/Urea solvent system. Thus, treating cotton cellulose with microwave oxygen plasma alters its physicochemical properties and enhanced its dissolution.

New paper!A Themed Issue in Honor of Professor Robin D. Rogers - "A Scientific Journey within Green Chemistry"Abstract: Innovative technologies can transform what are now considered “waste streams” into feedstocks for a range of products. Indeed, the use of biomass as a source of biopolymers and chemicals currently has a consolidated economic dimension, with well-developed and regulated markets, in which the evaluation of the manufacturing processes relies on specific criteria such as purity and yield, and respects defined regulatory parameters for the process safety. In this context, ionic liquids and deep eutectic solvents have been proposed as environmentally friendly solvents for applications related to biomass waste valorization. This mini-review draws attention to some recent advancements in the use of a series of new-solvent technologies, with an emphasis on deep eutectic solvents (DESs) as key players in the development of new processes for biomass waste valorization. This work aims to highlight the role and importance of DESs in the following three strategic areas: chitin recovery from biomass and isolation of valuable chemicals and biofuels from biomass waste streams.

Translation of new sustainable technologies from academia to industry and their commercialization is less based on the technology itself and more so on cost and demonstration of both viability and significant improvements over the current practice.
At the same time, scale up reactions from a lab scale to a commercial scale is a demanding process that requires experience and a wide range of components. Today, lets take a closer look at scale up solutions with our Master Student Nur Uddin.

Abstract
Abstract
The study evaluated the effect of cryogrinding, a relatively new, cost-effective, sustainable mechanical treatment method, on physicochemical properties of two different micronaire (3.6- and 5.3-) cotton fiber cellulose. Native (type I), mercerized (type II), and acidulated cellulose were subjected to cryogrinding for 48 and 96 min, and their physicochemical properties investigated. The results demonstrated that cryogrinding resulted in partial amorphization of native and mercerized celluloses, particle size decrease and slight reduction of decomposition temperature. Importantly, degree of polymerization (DP) of native cellulose reduced significantly: more than two-fold after 12 cycles and more than three-fold after 24 cycles of cryogrinding. No difference in properties was found between 3.6- and 5.3- micronaire cellulose. Advantageous impacts of cryogrinding found in this work will help signify potential of this technique in cellulose processing and enable the identification of areas for future development.

Abstract
Abstract
As the most abundant natural polymer, cellulose is a prime candidate for the preparation of both sustainable and economically viable polymeric products hitherto predominantly produced from oil-based synthetic polymers. However, the utilization of cellulose to its full potential is constrained by its recalcitrance to chemical processing. Both fundamental and applied aspects of cellulose dissolution remain active areas of research and include mechanistic studies on solvent–cellulose interactions, the development of novel solvents and/or solvent systems, the optimization of dissolution conditions, and the preparation of various cellulose-based materials. In this review, we build on existing knowledge on cellulose dissolution, including the structural characteristics of the polymer that are important for dissolution (molecular weight, crystallinity, and effect of hydrophobic interactions), and evaluate widely used non-derivatizing solvents (sodium hydroxide (NaOH)-based systems, N,N-dimethylacetamide (DMAc)/lithium chloride (LiCl), N-methylmorpholine-N-oxide (NMMO), and ionic liquids). We also cover the subsequent regeneration of cellulose solutions from these solvents into various architectures (fibers, films, membranes, beads, aerogels, and hydrogels) and review uses of these materials in specific applications, such as biomedical, sorption, and energy uses.

The Journal of Ionic Liquids is a high-quality international journal that reports academic and industrial research in the field of ionic liquids with a focus on fundamental measurements, molecular simulations, processes, and products.
It is the only journal primarily dedicated to articles based on ionic liquids research. Papers may be based on work that is experimental or theoretical, analytical or descriptive, chemical or physical. In addition to fundamental research (e.g., areas such as thermophysical properties, catalysis and chemical reactions, separations, interfacial phenomena, materials, toxicity, etc.), papers that focus on process design and development (e.g., synthesis and design methods, systems analysis, modeling, and scale-up, etc.) and product research and development (e.g. catalysts, polymers, coatings, membranes, lubricants, etc.) will also be considered.
In addition, papers dealing with new and commercial applications that fit the broad scope and objectives of the journal are encouraged.
We are pleased to inform you that this journal will waive the APC (Article Publishing Charge) until 31st May 2022. This will be applicable for any submissions received before this date, which are accepted for publication after peer review.

Predicted growth in plastic waste exceeds efforts to mitigate plastic pollution
This is a slide from recent Science paper. It shows plastic accumulated in rivers, lakes, and the oceans in million metric tons (Mt). The starting point is 2016, and the scale here from 2016 to 2030. Yellow area represents business as usual (BAU), in which plastic production and waste generation follow current trajectories; green/blue is an ambitious scenario draws upon existing global commitments to reduce plastic emissions; and violet is a target scenario <8 Mt (purple) scenarios. Orange horizontal line represents the target of <8 Mt, which is a frequently cited statistic in global policy discussions as an unacceptable amount of plastic emissions to the marine ecosystem alone. And what we can see here is that even in the best-case scenario, huge quantities of plastic will still accumulate in the environment. Realizing this, scientists turned their attention to bio-renewables – functional yet renewable alternatives to synthetic plastics.

Biomineral armor in leaf-cutter ants
Biomineral armor in leaf-cutter ants
A new study shows that one Central American leaf-cutter ant species has natural armor that covers its exoskeleton. This shield-like coating is made of calcite with high levels of magnesium, a type found only in one other biological structure: sea urchin teeth, which can grind limestone.

Before this finding, no type of calcite had been found in any adult insect. The discovery is especially surprising because the ants are well known. «There are thousands of papers on leaf-cutter ants», says study co-author Cameron Currie, an evolutionary biologist at the University of Wisconsin-Madison.

Dear all,
Dear all,
I have left Mari Signum July 31st, 2019. It has been a very hard decision for me to leave a company, since I invested too much time, efforts and energy into ‘our’ technology, including design and building laboratory from scratch, acquisition of equipment I hoped to work on myself, development QC/QA methods including those critical for the company, applying and receiving Green Chemistry Challenge Award, and so on. My previous job roles included leadership and making hard decisions, and this is one of the hardest I’ve made to date. I am returning to 525 Solutions, Inc.
