Published: November 2022

AbstractThis work reports a method and findings related to the enrichment of iron from bauxite waste (red mud) using chemical looping combustion (CLC). According to the results from X‐ray Diffraction, X‐ray Fluorescence, and scanning electron microscope–energy‐dispersive X‐ray spectroscopy, uniformly distributed iron in the red mud particles migrated outward to the surface during the 148 redox cycles in a bubbling fluidized bed reactor, in which the size‐reduced iron‐oxide particles due to attrition are concentrated in filters. The concentrations of iron oxide in raw particles and attrition fines are 43 wt.% and 83–87 wt.%, respectively. Since the attrition in CLC is inevitable, this recycled iron oxide can be a valuable by‐product to compensate for the cost of CLC, whereas the bed materials continue to participate in the CLC process. Moreover, the abundant bauxite waste can be processed in an eco‐friendly manner for integrated power generation, carbon capture, and iron recovery by the proposed strategy in this work.
Sustainable decision making for chemical process systems via dimensionality reduction of many objective problems
Authors: Russell Justin M. , Allman Andrew 
Published: November 2022

AbstractRecent global events and the rise of sustainable investing have made clear that the chemical and energy industry must consider sustainability goals beyond profit maximization to remain competitive. Multiobjective optimization provides an ideal framework for analyzing sustainability tradeoffs, but when four or more objectives are considered, the ability to rigorously solve problems and interpret results is lost. This necessitates an approach to systematically reduce the dimensionality of many objective problems to three or fewer objectives. In this work, an algorithm to group objectives based on their correlating nature a priori to solving the full space problem is proposed. It utilizes community detection on a novel weighted objective correlation graph to identify two or three groups of correlated objectives. Results from three representative case studies demonstrate that objective groupings obtained from this algorithm minimize the amount of tradeoff information lost and outperform intuitive groupings by economics or the environment.

AbstractThe crystallization process in small droplet possessed wide engineering applications in micromaterial fabrication and fine crystal screening. Herein, hydrophilic sessile platform via 3D printing technology was developed to facilely construct the interfacial confined droplets (ICDs) with a designed contact angle by conveniently regulating the droplet volume. The micro‐flows inside the droplet were adjusted by controlling the intensity of Marangoni flow and capillary flow within different droplet shapes (i.e., contact angle), which were verified by experimental and simulative results. Especially for the 120° ICD, the micro‐flows, achieved by the coordination of Marangoni flow and capillary flow, could convey solutes toward droplet center and harvest a standard cubic crystal at sessile platform center. These results indicated that ICD and sessile platform possessed great potential on high‐quality crystal screening and crystallization technique development, which additionally enriched the research strategy on crystal engineering.

AbstractMembranes with high ion selectivity and conductivity are critical for the wide application of electrochemical energy conversion and storage devices. Herein, functional molecular cross‐linked two‐dimensional zeolite nanosheets (ZN) with ‐NH2 and ‐SO3H groups are prepared and incorporated into sulfonated poly (ether ether ketone) (SPEEK) polymer matrix. These embedded nanosheets act as strong barrier to vanadium ions, while their internal pores provide transport channels for protons. In addition, the side functional groups grafted on ZN not only effectively enhance the surface affinity, but also bind and arrange the sulfonic acid groups of the polymer matrix to construct a continuous fast proton transfer pathway along the interface between SPEEK and ZN. Consequently, the hybrid membranes exhibit synchronously enhanced conductive‐ion selectivity and impressive performance with coulombic efficiency (CE) of ~99.0% and energy efficiency (EE) of ~85.0% at 120 mA cm−2, which is much higher than these of pure SPEEK (CE: ~97.8%, EE: ~78.4%) and Nafion 212 membranes (CE: ~96.3%, EE: ~80.1%). This functional‐designed hybrid approach provides a general strategy to develop high‐performance proton conductive membranes for energy‐related applications.

AbstractChromosome 1p36 deletion syndrome (1p36DS) is one of the most common terminal deletion syndromes (incidence between 1/5000 and 1/10,000 live births in the American population), due to a heterozygous deletion of part of the short arm of chromosome 1. The 1p36DS is characterized by typical craniofacial features, developmental delay/intellectual disability, hypotonia, epilepsy, cardiomyopathy/congenital heart defect, brain abnormalities, hearing loss, eyes/vision problem, and short stature. The aim of our study was to (1) evaluate the incidence of the 1p36DS in the French population compared to 22q11.2 deletion syndrome and trisomy 21; (2) review the postnatal phenotype related to microarray data, compared to previously publish prenatal data. Thanks to a collaboration with the ACLF (Association des Cytogénéticiens de Langue Française), we have collected data of 86 patients constituting, to the best of our knowledge, the second‐largest cohort of 1p36DS patients in the literature. We estimated an average of at least 10 cases per year in France. 1p36DS seems to be much less frequent than 22q11.2 deletion syndrome and trisomy 21. Patients presented mainly dysmorphism, microcephaly, developmental delay/intellectual disability, hypotonia, epilepsy, brain malformations, behavioral disorders, cardiomyopathy, or cardiovascular malformations and, pre and/or postnatal growth retardation. Cardiac abnormalities, brain malformations, and epilepsy were more frequent in distal deletions, whereas microcephaly was more common in proximal deletions. Mapping and genotype–phenotype correlation allowed us to identify four critical regions responsible for intellectual disability. This study highlights some phenotypic variability, according to the deletion position, and helps to refine the phenotype of 1p36DS, allowing improved management and follow‐up of patients.

Published: November 2022

AbstractTo describe the anterior segment (AS) findings in patients with microphthalmia with linear skin defects syndrome (MLS), also known as microphthalmia, dermal aplasia, and sclerocornea (MIDAS). A retrospective chart review was conducted to identify patients with a diagnosis of MLS syndrome seen at UPMC Children's Hospital of Pittsburgh. Ophthalmic examination, high‐frequency ultrasound, AS optical coherence tomography, and molecular testing were reviewed. Five female patients (10 eyes) were identified. One eye was anophthalmic, one was in a status post penetrating keratoplasty, and eight eyes presented with congenital corneal opacity (CCO). Of these, one showed a normal lens and a very small faint CCO; five showed congenital aphakia and characteristic silvery appearance of the cornea with vascularization; and two showed irido‐corneal adhesions in association with normal or abnormal lens and localized avascular CCO. Genetic testing was performed and revealed involvement of HCCS in four patients. In MLS patients, kerato‐irido‐lenticular dysgenesis can be associated with secondary CCO. It is important to distinguish these CCO from sclerocornea, in order to refine the appropriate management and counseling the parents about the prognosis.

AbstractIntroductionSynaptic failure, a hallmark of Alzheimer's disease (AD), is correlated with reduced levels of synaptic proteins. Though people with Down syndrome (DS) are at markedly increased risk for AD (AD‐DS), few studies have addressed synapse dysfunction.MethodsSynaptic proteins were measured in the frontal cortex of DS, AD‐DS, sporadic AD cases, and controls. The same proteins were examined in the Dp16 model of DS.ResultsA common subset of synaptic proteins were reduced in AD and AD‐DS, but not in DS or a case of partial trisomy 21 lacking triplication of APP gene. Pointing to compromised synaptic function, the reductions in AD and AD‐DS were correlated with reduced SNARE complexes. In Dp16 mice reductions in syntaxin 1A, SNAP25 and the SNARE complex recapitulated findings in AD‐DS; reductions were impacted by both age and increased App gene dose.DiscussionSynaptic phenotypes shared between AD‐DS and AD point to shared pathogenetic mechanisms.

AbstractPancreatic ductal adenocarcinoma (PDAC) is a highly malignant cancer of the digestive system common among humans. However, it is rarely reported in wild animals. In 2018, a giant panda died in the Beijing Zoo. During subsequent histological observation of the pancreas, it was discovered that the glandular epithelial cells had lost the pancreatic acinar structure, tubular areas with obvious structure in the pancreas, and the ductal epithelium was substituted by high columnar mucus cells. Masson staining showed that there were several fibrous tissue proliferative reactions around the ductal adenocarcinoma and immunohistochemical staining revealed that CK7 and CK19 were positively expressed in the pancreatic tissue. Therefore, the pathological diagnosis indicated that the panda had PDAC. In this paper, the panda's living conditions and pathological diagnosis results are examined, with the aim of providing a reference point for the future diagnosis of wild animal tumors.

Published: November 2022

AbstractTin halide perovskites (Sn HaPs) are the top lead‐free choice for perovskite optoelectronics, but the oxidation of perovskite Sn2+ to Sn4+ remains a key challenge. However, the role of inconspicuous chemical processes remains underexplored. Specifically, the halide component in Sn HaPs (typically iodide) has been shown to play a key role in dictating device performance and stability due to its high reactivity. Here we describe the impact of native halide chemistry on Sn HaPs. Specifically, molecular halogen formation in Sn HaPs and its influence on degradation is reviewed, emphasising the benefits of iodide substitution for improving stability. Next, the ecological impact of halide products of Sn HaP degradation and its mitigation are considered. The development of visible Sn HaP emitters via halide tuning is also summarised. Lastly, halide defect management and interfacial engineering for Sn HaP devices are discussed. These insights will inspire efficient and robust Sn HaP optoelectronics.

Published: November 2022

AbstractWe have employed in situ electrochemical shell‐isolated nanoparticle‐enhanced Raman spectroscopy (SHINERS) and density functional theory (DFT) calculations to study the CO reduction reaction (CORR) on Cu single‐crystal surfaces under various conditions. Coadsorbed and structure‐/potential‐dependent surface species, including *CO, Cu−Oad, and Cu−OHad, were identified using electrochemical spectroscopy and isotope labeling. The relative abundance of *OH follows a “volcano” trend with applied potentials in aqueous solutions, which is yet absent in absolute alcoholic solutions. Combined with DFT calculations, we propose that the surface H2O can serve as a strong proton donor for the first protonation step in both the C1 and C2 pathways of CORR at various applied potentials in alkaline electrolytes, leaving adsorbed *OH on the surface. This work provides fresh insights into the initial protonation steps and identity of key interfacial intermediates formed during CORR on Cu surfaces.
Dual‐Function Presodiation with Sodium Diphenyl Ketone towards Ultra‐stable Hard Carbon Anodes for Sodium‐Ion Batteries

Published: November 2022

AbstractHard carbon (HC) is a promising anode material for sodium‐ion batteries, yet still suffers from low initial Coulombic efficiency (ICE) and unstable solid electrolyte interphase (SEI). Herein, sodium diphenyl ketone (Na‐DK) is applied to realize dual‐function presodiation for HC anodes. It compensates the irreversible Na uptake at the oxygen‐containing functional groups and reacts with carbon defects of five/seven‐membered rings for quasi‐metallic sodium in HC. The as‐formed sodium induces robust NaF‐rich SEI on HC in 1.0 M NaPF6in diglyme, favoring the interfacial reaction kinetics and stable Na+insertion and extraction. This renders the presodiated HC (pHC) with high ICE of ≈100 % and capacity retention of 82.4 % after 6800 cycles. It is demonstrated to couple with Na3V2(PO4)3cathodes in full cells to show high capacity retention of ≈100 % after 700 cycles. This work provides in‐depth understanding of chemical presodiation and a new strategy for highly stable sodium‐ion batteries.
Synthesis and Degradation of Vinyl Polymers with Evenly Distributed Thioacetal Bonds in Main Chains: Cationic DT Copolymerization of Vinyl Ethers and Cyclic Thioacetals
Authors: Uchiyama Mineto , Murakami Yukihiro , Satoh Kotaro , Kamigaito Masami 
Published: November 2022

AbstractWe report a novel method to synthesize degradable poly(vinyl ether)s with cleavable thioacetal bonds periodically arranged in the main chains using controlled cationic copolymerization of vinyl ethers with a 7‐membered cyclic thioacetal (7‐CTA) via degenerative chain transfer (DT) to the internal thioacetal bonds. The thioacetal bonds, which are introduced into the main chain by cationic ring‐opening copolymerization of7‐CTAwith vinyl ethers, serve as in‐chain dormant species to allow homogeneous propagation of vinyl ethers for all internal segments to afford copolymers with controlled overall and segmental molecular weights. The obtained polymers can be degraded into low‐ and controlled‐molecular‐weight polymers with narrow molecular weight distributions via hydrolysis. Various vinyl ethers with hydrophobic, hydrophilic, and functional pendants are available. Finally, one‐pot synthesis of multiblock copolymers and their degradation into diblock copolymers are also achieved.

AbstractMetallic Zn is one of the most promising anodes, but its practical application has been hindered by dendritic growth and serious interfacial reactions in conventional electrolytes. Herein, ionic liquids are adopted to prepare intrinsically safe electrolytes via combining with TEP or TMP solvents. With this synergy effect, the blends of TEP/TMP with an IL fraction of ≈25 wt% are found to be promising electrolytes, with ionic conductivities comparable to those of standard phosphate‐based electrolytes while electrochemical stabilities are considerably improved; over 1000 h at 2.0 mA cm−2 and ≈350 h at 5.0 mA cm−2 with a large areal capacity of 10 mAh cm−2. The use of functionalized IL turns out to be a key factor in enhancing the Zn2+ transport due to the interaction of Zn2+ ions with IL‐zincophilic sites resulting in reduced interfacial resistance between the electrodes and electrolyte upon cycling leading to spongy‐like highly porous, homogeneous, and dendrite‐free zinc as an anode material.

Published: November 2022

AbstractSynthetic fluorescent protein chromophores have been reported for their singlet state fluorescence properties and applications in bioimaging, but rarely for the triplet state chemistries. Herein, we enabled their photo‐sensitizing and photo‐crosslinking properties through rational modulations. Extension of molecular conjugation and introduction of heavy atoms promoted the generation of reactive oxygen species. Unlike other photosensitizers, these chromophores selectively photo‐crosslinked aggregated proteins and uncovered the interactome profiles. We also exemplified their general applications in chromophore‐assisted light inactivation, photodynamic therapy and photo induced polymerization. Theoretical calculation, pathway analysis and transient absorption spectroscopy provided mechanistic insights for this triplet state chemistry. Overall, this work expands the function and application of synthetic fluorescent protein chromophores by enabling their triplet excited state properties.

Published: November 2022

AbstractSilphium integrifolium Michx. (Silflower) has been a promising subject for domestication as a perennial oilseed crop. This work was carried out to investigate the seed processing aspect of this effort. Thousand seed weight, densities, and dimension of the seeds were evaluated, seed milling to obtain enriched kernel fraction was conducted, and initial characterization of the seed protein was performed. There was wide variation in flat seed length (11.5–20.8 mm), width (4.6–11.8 mm), and thickness (0.9–1.6 mm). The thousand seed weight was 23.8 g but the tapped bulk density was only 189.6 g/L due to the presence of wing around the seed's periphery. The kernel accounted for 56.1% of the seed weight and contained 31.0% oil. A kernel‐enriched fraction with 79.6% purity was obtained by roller‐milling, sifting, and air classification. Linoleic (62.3%) and oleic (19.6%) acids were the major fatty acids in the oil. The defatted enriched kernel fraction contained 63.41% crude protein. Globulin, glutelin, albumin, and prolamin accounted for 55.6%, 19.3%, 16.4%, and 8.7% of the soluble proteins, respectively. At an extraction pH of 9, protein solubility was 62%. Maximum solubility (70%) was obtained at pH 10 while minimum solubility of 9% occurred between pH 4 and 5.5. Aside from the oil, the dehulling of silflower seeds also produced a high‐protein defatted meal, which may be used as is or as a starting material for enriching the protein further into a protein isolate.
Potential of microalgae for phytoremediation of various wastewaters for nutrient removal and biodiesel production through nanocatalytic transesterification

Published: November 2022

AbstractTetraselmis indica, a strain of microalgae, was cultivated in four distinct wastewaters in a photobioreactor of 1000 ml in a 16:8 light/dark period beneath the light intensity of 94.5 μmol m−2 s−1 for 14 days. The maximum biomass growth of 1125 mg/L was attained in the sewage wastewater (SWW). The T. indica eliminated the maximum pollution load from the primary wastewater of the paper mill (PWW), which was 94.95% nitrate, 96.625% phosphate, 99.5% ammonia, 72.8% COD, 94.14% BOD, and 98.9% TDS and heavy metals (94.84% Pb, 93.83% Mg, 99.78% Cu, 81.25% Mn, 94% Cd, 70.34% Zn, 99.84% Fe). The effectiveness of a lithium‐impregnated calcium oxide 1.75‐Li‐CaO nanocatalyst in the transesterification of microalgae was evaluated after growing an appropriate amount of microalgae on all four wastewaters. The nanocatalyst 1.75‐Li‐CaO was prepared by the wet impregnation method and characterized by various structural and spectral techniques. The scanning electron microscopy study shows the structure of nanocatalyst, which is in the shape of oval and hexagonal with a particle size of 20 nm. The Fourier transform infrared spectroscopy spectrum confirms that the nanocatalyst contains necessary functional groups, which were visible at 1470 cm−1. Because of its highest basic strength, 1.75‐Li‐CaO exhibits the highest activity for trans‐esterifying microalgal oil. The FAME profile of PWW‐based microalgae through nanocatalytic transesterification shows the existence of myristic acid (2.81%), stearic acid (5.28%), palmitic acid (38.74%), oleic acid (16.43%), linoleic acid (21.19%), and arachidic acid (5.85%). Thus, this research work validates that microalgae grown on SWW have the highest biomass output, and microalgae cultivated on PWW have the highest FAME yield when used to make biodiesel using nanocatalytic transesterification.
