Published: August 2023

AbstractFe(III) is introduced into ball clay by the peeling‐intercalation technique, and mixed with oyster shell (B‐FB‐OS), pelletized, and calcined to form granular materials (FB‐OS) demonstrated that the presence of SiO2 and Fe(III) is favorable for CaCO3 pyrolysis, and the pyrolysis temperature of CaCO3 in B‐FB‐OS is 46 °C lower than that of oyster shell. A large amount of flocculent products are generated on the surface of FB‐OS after phosphorus removal, but pore channels are still observed. EDS analysis and theoretical analysis show that the flocculent products contain Ca3(PO4)2, suggesting the occurrence of chemisorption. Fe3+/Ca2+ has synergism, the maximum adsorption capacity of FB‐OS is 244.65 mg g−1, and the phosphorus concentration after treatment is lower than 1 mg L−1. The kinetic adsorption behavior of FB‐OS is applicable to Pseudo‐second‐order rate equation. The results of the Weber–Morris model demonstrate that the adsorption process is controlled by outer film diffusion and intraparticle diffusion together. The thermodynamic behavior of FB‐OS is consistent with the Freundlich isotherm model (R2 = 0.945). The comprehensive analysis indicates that FB‐OS is multilayer adsorption and nonuniform surface adsorption, and has a strong phosphorus removal ability.

AbstractAb inito investigation of Perovskite/Silicon heterojunction solar cell is performed using SCAPS‐1D. Here, all‐inorganic lead‐free perovskite, CsSnI3, is investigated for solar cell with CsSnI3/n‐c‐Si configuration and a maximum efficiency of 26.52% is optimized. First, thickness optimization of CsSnI3/n‐c‐Si solar cell with Flat‐Band ohmic contact on both sides is performed for CsSnI3 and n‐c‐Si layers and is optimized to 10 nm for CsSnI3 and 175 µm for n‐c‐Si with 19.45% efficiency. Subsequently, doping concentration optimization of CsSnI3 and n‐c‐Si layers has furnished optimum 26.52% efficiency with 4.5 × 1017 cm−3 of CsSnI3 and 1.7 × 1018 cm−3 of n‐c‐Si. Effect of various metal contacts are investigated to find the feasible metal contact among Pt, Au, Al, Ag, and Cu. Pt and Au are found feasible for Front metal contact, whereas Al, Ag, and Cu are found feasible for Back metal contact. Moreover, the impact of CsSnI3/n‐c‐Si interface defects on performance parameters is investigated.

AbstractMemristors with nonvolatile storage performance and simulated synaptic functions are regarded as one of the critical devices to overcome the bottleneck in traditional von Neumann computer architecture. 2D van der Waals heterostructures have paved a new way for the development of advanced memristors by integrating the intriguing features of different materials and offering additional controllability over their optoelectronic properties. Herein, planar memristors with both electrical and optical tunability based on ReS2/WS2 van der Waals heterostructure are demonstrated. The devices show unique unipolar nonvolatile behavior with high Roff/Ron ratio of up to 106, desirable endurance, and retention, which are superior to pure ReS2 and WS2 devices. When decreasing the channel length, the set voltage can be notably reduced while the high Roff/Ron ratios are retained. By introducing electrostatic doping through the gate control, the set voltage can be tailored in a wide range from 4.50 to 0.40 V. Furthermore, biological synaptic functions and plasticity, including spike rate‐dependent plasticity and paired‐pulse facilitation, are successfully realized. By employing optical illumination, resistive switching can also be modulated, which is dependent on the illumination energy and power. A mechanism related to the interlayer charge transfer controlled by optical excitation is revealed.

Published: August 2023

AbstractTheir high tunability of electronic and magnetic properties makes transition‐metal oxides (TMOs) highly intriguing for fundamental studies and promising for a wide range of applications. TMOs with strong ferrimagnetism provide new platforms for tailoring the anomalous Hall effect (AHE) beyond conventional concepts based on ferromagnets, and particularly TMOs with perpendicular magnetic anisotropy (PMA) are of prime importance for today's spintronics. This study reports on transport phenomena and magnetic characteristics of the ferrimagnetic TMO NiCo2O4 (NCO) exhibiting PMA. The entire electrical and magnetic properties of NCO films are strongly correlated with their conductivities governed by the cation valence states. The AHE exhibits an unusual sign reversal resulting from a competition between intrinsic and extrinsic mechanisms depending on the conductivity, which can be tuned by the synthesis conditions independent of the film thickness. Importantly, skew‐scattering is identified as an AHE contribution for the first time in the low‐conductivity regime. Application wise, the robust PMA without thickness limitation constitutes a major advantage compared to conventional PMA materials utilized in today's spintronics. The great potential for applications is exemplified by two proposed novel device designs consisting only of NCO films that open a new route for future spintronics, such as ferrimagnetic high‐density memories.

AbstractMitochondrial neurogastrointestinal encephalomyopathy (MNGIE) is a rare autosomal recessive multisystem disorder that often presents with gastrointestinal and neurological symptoms. Here we report a 33‐year‐old male who presented with a 16‐year history of diarrhea with black stool and progressive weight loss. He complained of progressive bilateral blurred vision, upper eyelids heaviness, ocular motility impairment, and color blindness. Peripheral neuropathy, bilateral sensorineural deafness, hyperlactatemia, diabetes mellitus, hepatic steatosis, blood coagulation dysfunction, and diffuse leukoencephalopathy were detected in the systemic evaluation. Based on the novel homozygous pathogenic variant in the TYMP gene (c.1159+1G>A), he was diagnosed with MNGIE. On ophthalmic examinations, the thickness of the inner retina and ganglion cell complex significantly decreased. ERG showed diffusely decreased amplitudes. The electronegative electroretinogram, which was first reported in MNGIE, indicated a more severe inner retina impairment. The bilateral papillomacular bundle defect and central vision loss in MNGIE are consistent with classical mitochondrial optic neuropathies' features. According to the literature, pigmentary retinopathy, optic neuropathy, and abnormal pupillary reflexes are uncommon ocular features of MNGIE. This study contributes to a better understanding of ocular manifestations in MNGIE and demonstrates that MNGIE may have dyschromatopsia and an electronegative electroretinogram.

AbstractThe study of electroencephalographic (EEG) signals in nonhuman primates has led to important discoveries in neurophysiology and sleep behavior. Several studies have analyzed digital EEG data from primate species with prehensile tails, like the spider monkey, and principal component analysis has led to the identification of new EEG bands and their spatial distribution during sleep and wakefulness in these monkeys. However, the spatial location of the EEG correlations of these new bands during the sleep–wake cycle in the spider monkey has not yet been explored. Thus, the objective of this study was to determine the spatial distribution of EEG correlations in the new bands during wakefulness, rapid eye movement (REM) sleep, and non‐REM sleep in this species. EEG signals were obtained from the scalp of six monkeys housed in experimental conditions in a laboratory setting. Regarding the 1–21 Hz band, a significant correlation between left frontal and central regions was recorded during non‐REM 2 sleep. In the REM sleep, a significant correlation between these cortical areas was seen in two bands: 1–3 and 3–13 Hz. This reflects a modification of the degree of coupling between the cortical areas studied, associated with the distinct stages of sleep. The intrahemispheric EEG correlation found between left perceptual and motor regions during sleep in the spider monkey could indicate activation of a neural circuit for the processing of environmental information that plays a critical role in monitoring the danger of nocturnal predation.

AbstractObjectivesThis study presents isotopic information for incremental dentine collagen and bone bulk collagen from individuals from the Canary Islands (Tenerife and Gran Canaria) to explore dietary differences during childhood life.Materials and MethodsEight individuals have been studied, which comprises 122 δ15N and δ13C incremental dentine measurements and eight bulk bone collagen analyses. A baseline of potentially consumed food sources has been developed for comparative purposes. A food reconstruction using isotopic transferred signals (FRUITS) model of probable contributions of each food source towards the diet of each individual has been developed. All samples but one belongs to the later period of indigenous occupation of the archipelago.ResultsThe dentine collagen data are presented in correlated δ13C and δ15N plots per individual, showing the isotopic changes throughout time. δ15N values for each individual tend to be variable whereas δ13C data are generally more stable with a range of +9.1 to +14‰ for δ15N and −17.4 to −20.8‰ for δ13C.ConclusionThe isotopic analysis allows for the reconstruction of eight dietary profiles, which allow us to estimate the different dietary protein sources. The FRUITS model shows different percentages of the primary food sources for each individual. Where both δ13C and δ15N are elevated, this could be indicative of a higher marine contribution to the diet. There appear to be two main dietary profiles identifiable in the dataset and these may be related to changes in status or place of residence. Short‐term variations in δ13C and δ15N and opposing co‐variance of isotopic values can be indicative of nutritional stress, although metabolic changes during growth are also considered.

AbstractINTRODUCTIONMitochondrial dysfunction is implicated in the pathophysiology of many chronic diseases. Whether it is related to cognitive impairment and pathological markers is unknown.METHODSWe examined the associations of in vivo skeletal muscle mitochondrial function (post‐exercise recovery rate of phosphocreatine [kPCr] via magnetic resonance [MR] spectroscopy with future mild cognitive impairment (MCI) or dementia, and with positron emission tomography (PET) and blood biomarkers of Alzheimer's disease [AD] and neurodegeneration (i.e., Pittsburgh Compound‐B [PiB] distribution volume ratio [DVR] for amyloid beta [Aβ], flortaucipir (FTP) standardized uptake value ratio [SUVR] for tau, Aβ42/40 ratio, phosphorylated tau 181 [p‐tau181], neurofilament light chain [NfL], and glial fibrillary acidic protein [GFAP]).RESULTSAfter covariate adjustment, each standard deviation (SD) higher kPCr level was associated with 52% lower hazards of developing MCI/dementia, and with 59% lower odds of being PiB positive with specific associations in DVR of frontal, parietal, and temporal regions, and cingulate cortex and pallidum. Higher kPCr level was also associated with lower plasma GFAP.DISCUSSIONIn aging, mitochondrial dysfunction may play a vital role in AD pathological changes and neuroinflammation.Highlights
Higher in vivo mitochondrial function is related to lower risk of mild cognitive impairment (MCI)/dementia.
Higher in vivo mitochondrial function is related to lower amyloid tracer uptake.
Higher in vivo mitochondrial function is related to lower plasma neuroinflammation.
Mitochondrial dysfunction may play a key role in Alzheimer's disease (AD) and neurodegeneration.

AbstractLithium fluoride (LiF) at the solid electrolyte interface (SEI) contributes to the stable operation of polymer‐based solid‐state lithium metal batteries. Currently, most of the methods for constructing lithium fluoride SEI are based on the design of polar groups of fillers. However, the mechanism behind how steric hindrance of fillers impacts LiF formation remains unclear. This study synthesizes three kinds of porous polyacetal amides (PAN‐X, X=NH2, NH‐CH3, N‐(CH3)2) with varying steric hindrances by regulating the number of methyl substitutions of nitrogen atoms on the reaction monomer, which are incorporated into polymer composite solid electrolytes, to investigate the regulation mechanism of steric hindrance on the content of lithium fluoride in SEI. The results show that bis(trifluoromethanesulfonyl)imide (TFSI−) will compete for the charge without steric effect, while excessive steric hindrance hinders the interaction between TFSI− and polar groups, reducing charge acquisition. Only when one hydrogen atom on the amino group is replaced by a methyl group, steric hindrance from the methyl group prevents TFSI− from capturing charge in that direction, thereby facilitating the transfer of charge from the polar group to a separate TFSI− and promoting maximum LiF formation. This work provides a novel perspective on constructing LiF‐rich SEI.

AbstractHigh‐voltage lithium‐ion batteries (LIBs) have attracted great attention due to their promising high energy density. However, severe capacity degradation is witnessed, which originated from the incompatible and unstable electrolyte‐electrode interphase at high voltage. Herein, a robust additive‐induced sulfur‐rich interphase is constructed by introducing an additive with ultrahigh S‐content (34.04 %, methylene methyl disulfonate, MMDS) in 4.6 V LiNi0.5Co0.2Mn0.3O2 (NCM523)||graphite pouch cell. The MMDS does not directly participate the inner Li+ sheath, but the strong interactions between MMDS and PF6− anions promote the preferential decomposition of MMDS and broaden the oxidation stability, facilitating the formation of an ultrathin but robust sulfur‐rich interfacial layer. The electrolyte consumption, gas production, phase transformation and dissolution of transition metal ions were effectively inhibited. As expected, the 4.6 V NCM523||graphite pouch cell delivers a high capacity retention of 87.99 % even after 800 cycles. This work shares new insight into the sulfur‐rich additive‐induced electrolyte‐electrode interphase for stable high‐voltage LIBs.

AbstractAqueous Zn batteries are attracting extensive attentions, but their application is still hindered by H2O‐induced Zn‐corrosion and hydrogen evolution reactions. Addition of organic solvents into aqueous electrolytes to limit the H2O activity is a promising solution, but at the cost of greatly reduced Zn anode kinetics. Here we propose a simple strategy for this challenge by adding 50 mM iodine ions into an organic‐water (1,2‐dimethoxyethane (DME)+water) hybrid electrolyte, which enables the electrolyte simultaneously owns the advantages of low H2O activity and accelerated Zn kinetics. We demonstrate that the DME breaks the H2O hydrogen‐bond network and exclude H2O from Zn2+ solvation shell. And the I− is firmly adsorbed on the Zn anode, reducing the Zn2+ de‐solvation barrier from 74.33 kJ mol−1 to 32.26 kJ mol−1 and inducing homogeneous nucleation behavior. With such electrolyte, the Zn//Zn symmetric cell exhibits a record high cycling lifetime (14.5 months) and achieves high Zn anode utilization (75.5 %). In particular, the Zn//VS2@SS full cell with the optimized electrolyte stably cycles for 170 cycles at a low N : P ratio (3.64). Even with the cathode mass‐loading of 16.7 mg cm−2, the full cell maintains the areal capacity of 0.96 mAh cm−2 after 1600 cycles.

AbstractA main‐group catalysis‐based strategy to access 8‐membered carbocycles via the direct carbofunctionalization of 2‐phenethyl‐substituted 1,3‐dienes is disclosed. Through the intervention of an I(I)/I(III) catalysis cycle, the synthesis of densely functionalized, fluorinated benzocyclooctenes can be achieved in an operationally simple manner. Modulating the oxidation/activation regime, and the external nucleophile, the process has been extended to unify the challenging cyclization with formation of allylic C−O, C−N, and C−C bonds (>30 examples). Derivatization of the product benzocyclooctenes is demonstrated together with X‐ray conformational analysis, preliminary validation of enantioselective catalysis and a scalable resolution protocol.

AbstractIncorporating high‐energy ultraviolet (UV) photons into photothermal catalytic processes may enable photothermal‐photochemical synergistic catalysis, which represents a transformative technology for waste plastic recycling. The major challenge is avoiding side reactions and by‐products caused by these energetic photons. Here, we break through the limitation of the existing photothermal conversion mechanism and propose a photochromic‐photothermal catalytic system based on polyol‐ligated TiO2 nanocrystals. Upon UV or sunlight irradiation, the chemically bonded polyols can rapidly capture holes generated by TiO2, enabling photogenerated electrons to reduce Ti4+ to Ti3+ and produce oxygen vacancies. The resulting abundant defect energy levels boost sunlight‐to‐heat conversion efficiency, and simultaneously the oxygen vacancies facilitate polyester glycolysis by activating the nucleophilic addition‐elimination process. As a result, compared to commercial TiO2 (P25), we achieve 6‐fold and 12.2‐fold performance enhancements under thermal and photothermal conditions, respectively, while maintaining high selectivity to high‐valued monomers. This paradigm‐shift strategy directs energetic UV photons for activating catalysts and avoids their interaction with reactants, opening the possibility of substantially elevating the efficiency of more solar‐driven catalysis.

AbstractOne of the best elastomers for the inner liner of a tire is brominated butyl rubber (BIIR). On the other hand, cutting‐edge automobile technologies call for BIIR with enhanced curing, mechanical, and barrier qualities. Consequently, in this investigation, BIIR blends were created with different elastomers that have similar permeability qualities of BIIR but have improved physical properties. Elastomeric blends of BIIR with epoxidized natural rubber (ENR), hydrogenated nitrile rubber (HNBR), and polyepichlorohydrin rubber (CO) were prepared using a melt mixing procedure that could be scaled up for commercial use. The crosslinking behavior, physical, morphological, and barrier characteristics of the developed blends were assessed. The crosslinking properties of new blends revealed a 100% improvement in torque difference, indicating superior cocurability of them with other general‐purpose rubbers used in tire in comparison to the reference BIIR sample. It was also found that the newly developed blends have enhanced mechanical qualities without sacrificing the air impermeability of BIIR, which in turn gives the capacity to withstand high air pressures and thereby a decrease in rolling resistance.
