Authors: Kotliar Elena Romanovna , Alekseeva Elena Nikolaevna 
Published: November 2022

The subject of the study is the cultural code of Judaism in the visual semiosis of the Crimea. The object of the study is the traditional symbolism in the decor of the Jews of the Crimea: Ashkenazi Jews, Karaites and Krymchaks. The article uses the methods of cultural (semiotic, ontological and hermeneutic) analysis in the continuum of signs of the traditional Jewish semiosis, the idiographic method in the concept of the totality of signs, the method of analysis of previous studies, the method of synthesis in substantiating the morphology of signs. The following aspects of the topic are considered in the study: five main codes of Jewish culture are identified, their morphology and interrelationships are substantiated, as well as key meanings and the main central code. The main conclusions of the study are: 1.	The multiethnic landscape of Crimea is made up of the cultures of numerous ethnic groups. The main feature of the identification and self-identification of cultures is religion. The Jews of Crimea include Ashkenazi Jews, Karaites and Crimeans. A single source for cultural codes in the Jewish semiosis is the Torah (the Mosaic Pentateuch) for all three ethnic groups, and for two of them (Jews and Krymchaks), the interpretation of the Torah is also the Talmud. 2.	Based on the studied material, five main codes of the Jewish visual semiosis of the Crimea are identified, each of which unites a certain group of symbols: skewomorphic, phytomorphic, zoomorphic, numeric. The unifying code and the primary source of all codes is the code Book (Torah). The interrelationships between the codes, the key meanings – symbols of Creation, Paradise, Torah persons and Messianic aspirations are revealed. The semantic center of all codes is the repository of the Torah – Aron Hakodesh, and the Torah itself. Thus, the ring pattern "from Torah to Torah" is revealed. 3.	A special contribution to the research of the topic is the systematization of the cultural codes of the Jewish semiosis of the Crimea. The scientific novelty consists in the fact that for the first time a culturological analysis was carried out and the interrelationships of cultural codes in the visual semiosis of the Crimea were structured.

Published: November 2022

Aims: The study’s objective is to isolate, characterize pigment-producing bacteria from marine soil and to optimize culture parameters such as pH, temperature, carbon, nitrogen sources to enhance the pigment production. The obtained pigment was used to dye cotton fabrics and woollen thread.
Place and Duration of Study: The samples were collected from the Marina beach, Chennai, Tamil Nadu and the study was carried out at the Department of Animal Biotechnology, Madras Veterinary College, Chennai, between January 2021- April 2021.
Methodology: From the soil sample fast-growing yellow pigmented bacteria was isolated and the morphological characteristics were observed. Gram staining, biochemical test, sugar fermentation test, motility test was performed and 16S rDNA sequencing was done. Pigment was extracted through solvent extraction method, characterized through UV-Spec and FTIR. The phytochemicals test was done and the culture conditions were optimized to bring out maximum pigment yield. The pigment was then used to dye cotton fabrics and woollen threads.
Results: The isolated yellow-pigmented bacteria was identified as Citricoccus sp. and the pigment is confirmed as carotenoid compound and through optimizing the culture conditions, the pigment production was increased significantly. The woollen thread and cotton fabrics were dyed effectively and uniformly with the use of copper sulphate(CuSO4) as mordant.
Conclusion: The result of this study reveals that Citricoccus sp. is a fast-growing bacterium capable of producing a higher amount of pigment in 24-hour period. Since it is confirmed to be a carotenoid compound, it is safe to be used as a dye. The extraction process is cost-effective and economical, this study can be expanded to explore the potential applications of the pigment in the textile and dyeing industries.
Current scientific interest in dissociative amnesia: A bibliometric analysis
Authors: Pope Harrison G. , Schnabel Jiana , Hudson James I. 
Published: November 2022

AbstractIn a bibliometric analysis, we used the PubMed search engine to count the number of publications identified by the search term “dissociative amnesia” for the years 2011–2020. We then counted publications from the same decade for five representative comparison disorders: “panic disorder,” “anorexia nervosa,” “obsessive–compulsive disorder,” “attention deficit hyperactivity disorder,” and “bipolar disorder.” Our search yielded only 89 publications for “dissociative amnesia,” and only seven of these involved localized or selective amnesia for specific events. By contrast, we found between 3000 and 21,000 publications for each of the five comparison disorders during 2011–2020. We performed several additional secondary analyses, all of which suggested that the diagnosis of “localized or selective dissociative amnesia” has generated little scientific interest in recent years. Examining possible hypotheses to explain this lack of interest, it appears most likely that the concept of localized or selective dissociative amnesia is not widely accepted among scientists at present.
Circadian Rhythm Changes in Healthy Aging and Mild Cognitive Impairment
Authors: Keihani Ahmadreza , Mayeli Ahmad , Ferrarelli Fabio 
Published: November 2022

AbstractDisruptions in circadian rhythms can occur in healthy aging; however, these changes are more severe and pervasive in individuals with age‐related and neurodegenerative diseases, such as dementia. Circadian rhythm alterations are also present in preclinical stages of dementia, for example, in patients with mild cognitive impairments (MCI); thus, providing a unique window of opportunity for early intervention in neurodegenerative disorders. Nonetheless, there is a lack of studies examining the association between relevant changes in circadian rhythms and their relationship with cognitive dysfunctions in MCI individuals. In this review, circadian system alterations occurring in MCI patients are examined compared to healthy aging individuals while also considering their association with MCI neurocognitive alterations. The main findings are that abnormal circadian changes in rest‐activity, core body temperature, melatonin, and cortisol rhythms appear in the MCI stage and that these circadian rhythm disruptions are associated with some of the neurocognitive deficits observed in MCI patients. In addition, preliminary evidence indicates that interventions aimed at restoring regular circadian rhythms may prevent or halt the progress of neurodegenerative diseases and mitigate their related cognitive impairments. Future longitudinal studies with repeated follow‐up assessments are needed to establish the translational potential of these findings in clinical practice.

AbstractMagnetic skyrmions are localized particle‐like nontrivial swirls that are promising in building high‐performance topological spintronic devices. The read‐out functions in skyrmionic devices require the translation of magnetic skyrmions to electrical signals. Here, combined real‐space magnetic imaging and anisotropic magnetoresistance studies on dipolar skyrmions are reported. A single skyrmion chain and single skyrmion are observed using Lorentz transmission electron microscopy imaging. Meanwhile, the field, helicity, and skyrmion count dependence of anisotropic magnetoresistance of the Fe3Sn2 nanostructures are obtained simultaneously. These results demonstrate that the anisotropic magnetoresistance of skyrmions is independent of the helicity and proportional to the skyrmion count. This study promotes read‐out operations in skyrmion‐based spintronic devices.

Published: November 2022

AbstractBiomimetic smart nanochannels can regulate ion transport behavior responsive to the external stimuli, having huge potential in nanofluidic devices, sensors and energy conversion. Field‐effect nanofluidic diodes or transistors based on electric‐responsive nanochannels are emerging owing to their advantages such as non‐invasiveness, in situ, real time, and high efficiency. However, simultaneously realizing the voltage‐control of the ion conductance and ion current rectification (ICR) properties is still a big challenge. Here, a field‐effect iontronic device is developed based on ionomer/anodic aluminum oxide/conducting polymer sandwich‐structured nanochannel to realize the multi‐control of ion transport behaviors including ion conductance, ICR magnitude, and ICR direction by modulating the surface charge, wettability, and morphology of the nanochannel. The electroactive conducting polymer carries tunable surface charges responsive to the electric stimuli, leading to the regulation of ICR values. The complex three‐segment structures lead to the reverse of ICR direction by reconfiguring the charge distribution along with the whole channel. The switching wettability between hydrophilic and hydrophobic results in the regulation of ion conductance. Furthermore, the field‐effect iontronic device functions in a wide salinity range especially in hypersaline environment, due to the salinity‐adaptive properties of the membrane. A new route is provided for designing more functional field‐effect nanofluidic devices.

AbstractA prevalent problem of magnetic resonance imaging (MRI) contrast agents (CAs) for drug loading applications is easy aggregation. The major concern of hollow mesoporous organosilica nanoparticles (HMONs) is hard control of untimely drug leakage. To overcome both problems, a new strategy of limited‐space controlled aggregation for generic enhancement of drug loading capability is proposed. Typically, MRI CAs of exceedingly small gadolinium oxide nanoparticle (GO) and Gd poly(acrylic acid) macrochelate (GP) are exploited to load doxorubicin (D) in HMONs hollow core. The GO@D@HMONs and GP@D@HMONs without precipitation formation display much higher drug loading contents (33.0 ± 4.9%, 39.6 ± 4.0%) than GO@D and GP@D with serious precipitation generation (4.7 ± 0.5% and 14.7 ± 3.4%), which can be ascribed to the generation of GO@D and GP@D aggregates with larger sizes in HMONs hollow core than the pore size of HMONs preventing the drug leakage. The tumor microenvironment (TME)‐specific glutathione (GSH)‐triggered degradation of HMONs and the controlled drug release behaviors reinforce the chemotherapeutic efficacy and alleviate side effects on normal cells/tissues. The GSH‐activatable T1‐MRI is favorable to high contrast tumor imaging. Overall, the strategy of limited‐space controlled aggregation is promising for generic enhancement of drug loading capability of MRI CAs, realizing MRI‐guided high‐performance cancer treatments.

AbstractThe CK bond plays a significant role in stabilizing the Na‐K (NaK) alloy electrodes due to the enhancive interfacial affinity. In this study, a method for constructing semi‐solid K metal electrodes with rich CK bonds by in situ replacement of N‐doped carbon nanotubes (CNT) and liquid NaK alloy is proposed. Based on the in situ infrared thermal imaging technique combined with heat calculation, X‐ray photoelectron spectroscopy elemental analysis, and reaction thermodynamic calculation, graphite‐N, which is widely distributed on the wall of CNT, offers plenty of replacement sites for forming CK bonds. Due to the rich bonds, the amount of CNT sharply reduces in dendrite‐free semi‐solid CNT@NaK electrodes and the activity of NaK alloy raises to ≈90%. This discovery provides a new idea for establishing dendrite‐free anodes for K metal batteries.

Published: November 2022

AbstractPeptides show tremendous promise in synthesizing metal–peptide superstructures with tailored shapes and functions. However, bottom‐up control of the polymorphs of these superstructures using a single short peptide without molecular modification has not been mechanistically clarified. Therefore, an approach to constructing gold–peptide superstructures with unprecedented structural diversity using a tyrosine‐rich short peptide is developed, based on the assembling and mineralizing attributes of tyrosine. One‐step UV irradiation of peptide/gold‐salt systems enables on‐site mineralization of gold ions, permitting controlled solvent‐dependent fabrication of various superstructures. 0D colloids, 2D sheets, 3D superspheres, and 3D hollow capsules are produced via one‐pot reactions in a pH‐10 buffer, at the interface of a toluene–water biphasic system, in water, and in toluene‐in‐water emulsions, respectively, whereas 1D rod/fibril structures are produced using rapidly assembling peptides (A, F, I, L, N, V, Y, and D as X in YY‐X‐YY) in a two‐step process. Several peptide derivatives, which also exhibit assembling and biomineralizing abilities and form various superstructures, validate the functionality of the tyrosine‐rich peptide. This study sheds light on the design and development of diverse gold‐peptide superstructures for applications including catalysis, sensing, imaging, and photothermal therapy.

AbstractThe continuation of human civilization has always been accompanied by symbiosis and confrontation with fire. Particularly, humans can comprehensively recognize fire situations based on various sensory receptors in organs (eyes, skin, nose, etc.), further forming a sound fire perception system by in‐the‐brain recording, modeling, and understanding fire behaviors, leading to the most accurate fire treatments. If a sensing perception system can mimic human perceptual behavior and carry out real‐time fire recognition, such an active defense system can achieve real fire safety. Here, inspired by the brain‐centered perception system, an early‐fire perception system enabled by a VO2‐based temperature‐flame‐modulated optical switch, and a machine‐learning‐assistant demodulation algorithm is reported. This approach creates real‐time monitoring composed of early fire warning (1 s for candle flame and 4 s for 130 °C heat flow), fire cause recognition (95.7% accuracy in identification), and evacuation advice provision, advancing the technologies in the perception system that enable future sensors the comprehensive perception capability for fire state.

AbstractInterface exciplex represents a promising host material for organic light‐emitting diodes (OLEDs) with barrier‐free charge injection and highly confined recombination region. However, the efficiency of radiative recombination in pristine exciplex is usually low and needs to be improved by doping various emitters. In this study, the interface exciplex OLEDs doped with fluorescence, phosphorescence, and thermally activated delayed fluorescence (TADF) emitters is fabricated to investigate the relationship between their excited‐state properties and electroluminescence efficiencies. A maximum external quantum efficiency of 20% is achieved in interface exciplex OLEDs doped with TADF emitter, which corresponds to nearly 100% exciton utilization and is superior to those of fluorescence and phosphorescence emitters. Furthermore, optical spectroscopy and magneto‐electroluminescence method are used to study the advantages of TADF emitter in interface exciplex host. The large dipole of TADF emitter is beneficial for harvesting energy from the charge‐transfer state at the interface, and its reverse intersystem crossing avoids the accumulation of triplet excitons that leads to triplet‐triplet annihilation in interface exciplex OLEDs. These results demonstrate that the photophysical process needs to be carefully considered in designing high‐performance emitters for exciplex host materials, and it may bring in‐depth understanding on improving exciton utilization and electroluminescence efficiency in interface exciplex OLEDs.

AbstractNi‐rich layered oxides as the cathode materials of high‐energy‐density lithium‐ion batteries (LIBs) suffer from capacity decay and structural instability owing to oxygen loss during cycling. It is a huge challenge to prevent the oxygen loss of Ni‐rich cathode materials during long cycling. Here, a pre‐deoxidation of LiNi0.8Co0.1Mn0.1O2 (NCM811) single crystal materials is achieved by heat treatment at elevated temperatures in argon condition to form a stable surface with rock salt structure. The stable surface structure with oxygen vacancy defects successfully suppresses the harmful phase transitions of NCM811 and effectively improves the stability of the NCM811/electrolyte interface during cycling at a high cut‐off voltage. In addition, the intragranular structural evolution and cation mixing degree is inhibited to effectively suppress the intergranular cracking and particle pulverization of cathode during long cycling. The pre‐deoxidation of NCM811 exhibits 70.6% capacity retention after 1000 cycles at the current density of 0.5 C between 2.8 and 4.3 V, which is much larger than that of pristine NCM811 capacity retention of 27.3%. The strategy of pre‐deoxidation of Ni‐rich layered structure cathode to regulate the defect chemistry and surface structure provides a facile and effective way to achieve long cycling life high‐energy density LIBs.

AbstractFerroptosis is recently discovered programmed cell death, induced by cellular ferrous ion bursts and subsequent Fenton reactions. The iron source in tumor cells is limited due to tightly controlled iron metabolism. Since hierarchical iron architecture is rarely considered in ferroptosis cancer treatment, multilayer Fe2O3 architectures (UF@PPDF NPs) are developed by modulating ultra‐small γ‐Fe2O3 nanocrystal assemblies, and further conjugating cancer cell targeting folic acid (FA), chemotherapeutic drug doxorubicin (Dox). Hierarchically assembled γ‐Fe2O3 nanocrystal facilitates switchable magnetic resonance imaging (MRI), much enhanced ferroptosis efficiency, and very high second near‐infrared (NIR‐II) photothermal conversion. For MRI, UF@PPDF nanoparticles (NPs) enables clearly visualized tissues in terms of size and compactness, with dynamic T2‐T1 imaging switching. UF@PPDF NPs exhibits highly efficient photothermal therapy (PTT) upon NIR‐II irradiation, together with controlled release of ferric ions and Dox, thus achieving PTT‐chemotherapy‐ferroptosis trifunctional synergistic cancer therapy for tumor ablation. RNA sequencing analyses of differentially expressed genes implies a multifaceted role for this therapy in cancer cell signaling. Cellular respiration and electron transport are significantly upregulated, while the epigenetic pathways, including chromatin modification and RNA transcription activity are severely downregulated, with an overall effect of cellular apoptosis. Thus, γ‐Fe2O3 architectures provide new possibility for highly efficient deep tumor treatment.

Published: November 2022

AbstractThe fundamental challenges that coexisted around sulfur cathode energy storage systems, are the severe polysulfide dissolution and low reactivity resulting in poor reversibility and short cycle life, specifically, in inexpensive sodium ion batteries. Herein, the solution‐processed synthesis of ultra‐high intimate contacted FeS2/S architecture is reported and evolution of the dynamic multistage coupling between the FeS2 and S in sodium–sulfur batteries is revealed. Atomic visualization and in situ spectroscopy conclude that: NaxFeS2 (0 <x ≤1) effectively captures sodium polysulfides and promotes the conversion of S8 to Na2S4 to Na2S2/Na2S; simultaneously, the presence of Na2S2/Na2S traps the continuous growth of iron grains during continuously discharging to 0.4 V, thereby boosting the reversibility and high capacity. Moreover, the density functional theory further analyses the unique coupling effect of Na2Sx with different intermediate states of FeS2. The electrode with unique structure and dynamic coupling exhibits outstanding cycle reversibility and extremely long life, which delivers a reversible capacity of 860 mAh g−1 after 1000 cycles with no capacity decay at 0.5 A g−1. Even under a practical areal capacity of 4 mAh cm−2, it still shows pretty‐well cycling stability.

AbstractThe synthesis of fundamentally small MoS2 nanotubes and nanocones(horns) that have proven elusive in prior studies has been achieved via ablation of a precursor mixture of crystallites of MoS2 + MoO3 by highly concentrated solar radiation. The special far‐from‐equilibrium conditions achieved in the solar furnace prove conducive to the generation of these singular nanostructures. Extensive electron microscopy and characterization results (transmission electron microscopy (TEM), electron diffraction (ED), X‐ray diffraction (XRD), scanning TEM (STEM), and high angle annular dark field (HAADF)) reveal a range of nanoparticle shapes and sizes based on which reaction mechanisms are proposed. Molecular dynamics simulations indicate that the sizable thermal fluctuations intrinsically produced in the high‐temperature solar reactor soften the MoS2 nanostructures, yielding corrugated layers that favor nanostructures with only a few layers, in agreement with the experimental observations.
