Actividad Bioersoiva de Briozoos Ctenostomados en el Ordovícido Superior de la zona Cantábrica del Macizo Hespérico (Cabo Vidrias, Oviedo)
Authors: Mayoral Eduardo 
Published: September 2022

El estudio de las faunas de braquiópodos del Ordovícico Superior de la zona cantábrica del Macizo Hespérico (Costa de Asturias al NO de Oviedo), ha puesto de manifiesto la existencia de una intensa actividad perforadora atribuida a la acción de Briozoos Ctenostomados que constituyen uno de los registros estratigráficos más antiguos de este Orden. Se propone la adopción de una nueva icnoespecie: Pinaceocladichnus bulbosus nov. icnoesp. para referirse a los modelos de perforación exhibidos, que son diferentes de los hasta ahora reseñados en la bibliografía.Se describen todas las características morfológicas que los definen y se apunta la posibilidad de que sean el origen a partir del cual se desarrollen otros modelos mejor conocidos, merced a que presentan una serie de rasgos que luego evolucionarán de forma más acusada durante el Paleozoico.

Published: September 2022

Se estudia la fauna de foraminíferos planctónicos de un sondeo en materiales cuaternarios localizado en el mar de Alborán (Mediterráneo occidental), los más antiguos de los cuales alcanzan una edad algo superior a los 10.500 a. A. P. La inspección visual, el análisis de grupos y el análisis factorial en modo Q permiten establecer la existencia de tres grupos de especies. El primero, que incluye Globorotalia inflata (d'Orbigny), Globigerina bulloides d'Orbigny y Globorotalia truncatulinoides d'Orbigny, es un tanto artificial. El segundo integra Neogloboquadrina pachyderma (Ehrenberg), Neogloboquadrina dutertrei (d'Orbigny), las formas interme­dias entre N. pachyderma y N. dutertrei, y Globigerina quinqueloba Natland. El tercero esta formado por Globigerinoides ruber (d'Orbigny). Los resultados de las funciones de transferencia y los diagramas TS permiten inferir un cambio paleoceanográfco, consistente en un aumento, con dos oscilaciones importantes, de la temperatura y la salinidad de las aguas superficiales del mar de Alborán durante el intervalo de tiempo comprendido entre 10.500 y 7.000 a. A. P. Ahora bien, algunos de los cambios en la abundancia relativa de las especies más importantes no son siempre correlativos con estos cambios paleoceanográficos y para explicarlos se debe tener en cuenta la intervención de otros factores, tales como la productividad y la estratificación de las aguas.
Tipos de disgregación post mortem de la concha en braquiópodos actuales.
Authors: Emig Christian 
Published: September 2022

La disgregación post mortem de la concha de braquiópodos, bajo condiciones normales, se realiza mediante un proceso de alteración de la matriz orgánica, que depende de la estructura y de la composición de la concha, y un proceso de disolución (y/o recristalización) que depende directamente de las condiciones ambientales locales. Estos procesos son responsables de una pérdida tafonómica con una importante "infra-representación" de los braquiópodos y de una débil contribución de la fracción biodetrítica del sedimento. Se han observado cuatro tipos generales de disgregación. Tipo I: concha quitino-fosfática con dos capas (Lingula y Glottidia). degradación muy rápida acelerada por la abrasión mecánica hasta una desaparición total de las conchas vacías en el sedimento (en 2-3 semanas). Tipo II: concha carbonatada con dos capas (Terebratulina). alteración de la matriz orgánica, ablandamiento y total disgregación de la estructura de la concha (en 6-7 meses), aportación en microfibras de calcita al sedimento. Tipo III: concha carbonatada con dos capas de los rinconélidos como Notosaria, no sufre un "ablandamiento". Tipo IV: concha carbonatada con tres capas (Gryphus vitreus), alteración, ablandamiento y disolución y/o recristalización, fragmentación mecánica de la concha, aportación en trozos al sedimento.

Published: September 2022

AbstractDue to the efficient photoinduced charge transfer properties of nonmetals, nonmetallic surface‐enhanced Raman scattering (SERS) substrates have been advanced rapidly these years. And among of these, molybdenum disulfide (MoS2) is perceived as one of the most representative nonmetallic SERS substrates due to its abundant active sites. However, its progress in SERS field is severely hindered because of the lower SERS activity. Herein, one type of vacancies‐triggered highly sensitive SERS substrate based on nanostructured MoS2 with sulfur vacancies (VS) is proposed. The VS‐MoS2 substrates are intended to promote the SERS performance through the VS density regulation. Intrinsically, moderate VS can change the bandgap structure of MoS2, thus promoting the separation of internal carriers and enhancing the interaction with target species. Externally, the presence of VS can bring abundant adsorption sites on MoS2 surface, which greatly improves its ability to enrich target molecules. Both internal and external properties make VS‐MoS2 a high SERS activity substrate. Moreover, with the antibiotic contaminant diclofenac as a model probe molecule, the VS‐MoS2 substrate can accurately perceive its nanomolar concentration level with an enhancement factor up to 5.85 × 103. This work demonstrates exciting potential for analysis in real water environments based on nonmetallic SERS applications.

Published: September 2022

AbstractElectromagnetic vortices have attracted vast interest for their unique physics and promising applications. Tremendous efforts have been devoted to vortex generations, but receiving vortex modes remains challenging and commonly requires spatial phase gradient measurements. Here, a compact microwave vortex transceiver system based on reversible superposition and decomposition of degenerate and orthogonal dipole modes is reported. Identical plasmonic resonators are designed as both transmitting and receiving antennas. The received vortex modes are conveniently characterized by amplitude and phase signals measured at the receiving resonator ports. The transmitted orbital angular momentum (OAM) can be continuously tunable while the topological charge maintains discrete values of ±1. A transceiver system for degradation and reconstruction of OAMs is experimentally constructed, which can dynamically tune the vortex modes via simple voltage modulations. This research provides a convenient solution to transmit and receive microwave vortices, and paves novel routes for sensing and wireless communications based on continuously tunable vortex modes.

AbstractAs a new emerging semiconductor with interlayer bandgap, lead selenide (PbSe) have broad prospects in the fields of electrocatalysis, photocatalysis, infrared optoelectronic devices, optoelectronics, and ultrafast photonics. Among them, ultrafast photonics is receiving a lot of attention due to its ultrashort pulse, strong peak power, narrow bandwidth, and high repetition frequency. Herein, the properties are systematically studied of PbSe through various characterization methods. The modulation depth of PbSe is up to 30%, and its saturation light intensity is 7.86 MW cm−2. Using the evanescent field effect, nonlinear fiber‐based photonics devices has been successfully prepared based on the PbSe nanosheet solution, which can increase the bearable pump power. The 36th picosecond harmonic mode‐locked soliton molecule is generated in the erbium‐doped fiber laser, which corresponds to a maximum repetition frequency of 222 MHz. The results show that the signal‐to‐noise ratio can reach up to 49.1 dB which is higher than most previous works by now. The results revealed the potential of PbSe as an excellent photonics material in applications such as nonlinear optics, ultrafast photonics equipment, photoconductive detectors, and light modulators.

Published: September 2022

AbstractAqueous Zn‐organic batteries have received considerable attention owing to their green, low‐cost and high safe nature. Unfortunately, organic materials generally exhibit insulator nature (≈10−10 S cm−1), and most of reported promising performances of Zn‐organic batteries are achieved with a low mass‐loading (≈2 mg cm−2) in cathode, which is far away from practical application (10 mg cm−2). Herein, we demonstrate a semi‐conductive polymer poly(1,8‐diaminonaphthalene) (PDAN) cathode material for Zn batteries, which shows a moderate electronic conductivity (5.9×10−5 S cm−1). Theoretical calculations and in situ/ex situ analysis reveal that the cathode involves a bipolar‐type charge storage mechanism. Accordingly, the Zn//PDAN cell exhibits a promising capacity (140 mAh g−1at 0.1 A g−1) and a remarkable cycle stability (1000 cycles without capacity fading) at a high mass‐loading (10 mg cm−2). These encouraging results shed light on the design of advanced organic electrode.
Development of hybrid hydrogel to facilitate knee joint movement with an engineering approach
Authors: Göncü Yapıncak 
Published: September 2022

AbstractHyaline cartilage can be defined as a “biological bearing material” with an engineering approach. Movement causes friction between joints while lubricants provide separation between the two surfaces, reducing or preventing frictional wear. This study describes an injectable hybrid hydrogel consisting of a hyaluronic acid matrix filled with hexagonal boron nitride (hBN) particles that can mimic the rheological properties of joint fluid. hBN is a good lubricant and a strong candidate for biomedical applications with its unique tribological properties. The hypothesis established is that the lubricating property of hBN may alleviate the symptoms of osteoarthritis (OA) and improve the person's life quality. A new formulation and strategy for articular injections are proposed. The focus of the present work is the presentation of the rheological profile of hyaluronic acid‐boron nitride (HA‐hBN) hybrid hydrogels. Structural and physical characterizations have shown that BN‐HA hybrid hydrogels can be produced in injectable form, their compatibility with HA strongly depends on surface modification of BN, and they are promising candidates for the treatment of OA by evaluating the frequency range of walking and running.

AbstractThe fall armyworm (FAW) Spodoptera frugiperda is an important invasive pest in Africa and Asia. It is a polyphagous pest with at least 353 recorded host plant species, including corn. Chemical control of this pest is unsuccessful because of a developed resistance and harmful effects on the environment. Entomopathogenic fungi are potential biological control agents for FAW. In this study, the native strain of Metarhizium rileyi (KNU‐Ye‐1), collected from a cornfield at Yeongcheon, Korea, was identified by morphological and molecular characterization. The susceptibility of the fourth‐instar larvae of FAW to the native strain M. rileyi was examined in the laboratory. The results showed that the Korean strain of M. rileyi (KNU‐Ye‐1) was highly virulent to FAW larvae, causing 89% mortality 7 days posttreatment. Therefore, M. rileyi (KNU‐Ye‐1) identified in this study is highly valuable for the biological control of FAW in the field.
From waste to market: Exploring markets, institutions, and innovation ecosystems for waste valorization
Authors: Nogueira Leticia Antunes , Lindeløv Bjarne , Olsen Julia 
Published: September 2022

AbstractThis article explores the emergence of waste valorization innovations to investigate how they interact with incumbent waste management systems and what roles markets play in the process. We build upon innovation ecosystems as an analytical framework and investigate empirically three cases distributed across the waste hierarchy pyramid: (i) upcycling of discarded fishing gear; (ii) reusing constructions and recovering demolition waste; and (iii) establishing a biomass‐based district heating facility. Our cases indicate that waste valorization initiatives are deeply entangled in incumbent waste management systems and that markets alone appear to be insufficient to drive innovations in waste valorization. Our analysis also points to a relationship between the position of waste innovation in the waste hierarchy and the presence and effectiveness of markets. Markets function better when resources already have some economic value, which is what waste valorization processes seek to obtain. When the environmental value is higher than the economic value, other mechanisms are needed to enable innovations, markets, and sustainability transitions. Support from the public sector in various capacities, from international regulation to demand shaping, seems to be essential for circular economy transitions. Understanding issues such as how waste innovations reach the market and how markets for waste resources function is imperative for circular economy transitions.
Inter‐judicial differences in approaching technical violations: Examining the interaction of judge and compliance issue for domestic violence probationers

Published: September 2022

AbstractFew studies have examined differences in the sentencing practices of judges within a jurisdiction. Even more limited is research examining differences across judges in domestic violence courts despite the large amount of discretion afforded to judges in these courts in sanctioning decisions. The current study utilized data from a large urban county court to determine whether significant differences existed across judges in allocating a jail sanction in the domestic violence court. Three hundred forty seven probation review hearings in which at least one act of noncompliance were examined. Findings suggest significant differences in the use of jail for prohibited substance abuse, but not for other forms of noncompliance. The implications of these findings are discussed.

AbstractEssential oils produced by Cymbopogon distans and Ruta graveolens with a similar Chinese name could be explained as book fragrance in the Chinese idiom ‘shu xiang men di’, namely, a wealthy intellectual family according to ancient Chinese. Therefore, volatile oils from these two plants and their main compounds were tested to explore their antifungal, repellent, and insecticide actions. In this study, the essential olis (EO) of C. distans exhibited significant antifungal activity against Rhizopus stolonifera (97 %), Mucor racemosus (97 %), and Trichoderma viride (84 %); its main compounds exhibit interesting activity, such as methyleugenol (87 %) and elemicine (85 %) against T. viride and butyl hydroxytoluene against M. racemosus (90 %) and R. stolonifera (95 %). The EO of R. graveolens and other major chemical constituents showed weak inhibitory effects against other fungi (Aspergillus flavus and Fusarium oxysporum). Then, EO (C. distans and R. graveolens) and its main compounds exhibited obvious repellent activity (more than 85 %) at a concentration of 16 nL/cm2, which was consistent with the repellency of the positive control (DEET). In terms of insecticidal activity, the mortality of C. distans volatile oil against R. padi (56.4 %) was lower than that of R. graveolens volatile oil (92.4 %), and all compounds showed weak lethal effects. These results provide a natural substance for controlling fungi and insects when storing books and that can be used as a biological pesticide for industrial production. Through our study, the book fragrance in the Chinese idiom ‘shu xiang men di’ was speculated to be the EO odor of C. distans.

Published: September 2022

AbstractSolar energy‐driven overall water splitting (OWS) is an attractive way for generating clean and renewable green hydrogen. One key challenge is the construction of OWS systems with high solar energy conversion efficiencies, in which how to manipulate photoexcited charge carriers to efficiently participate in the reaction is the top priority. In recent years, bismuth vanadate (BiVO4) has emerged as one of the most promising materials for photo(electro)catalytic OWS and considerable progress has been achieved. In this review, recent advances of BiVO4‐constituted OWS systems in both photoelectrocatalytic and photocatalytic approaches are presented in a mainline of effective charge carrier utilization. Various strategies for improved charge carrier utilization, including band structure engineering, improving charge separation, reducing charge recombination, and accelerating reaction kinetics, are summarized and analyzed in detail. Finally, perspective and outlook on further exploring the application potential of BiVO4 are proposed.
Cucurbit[7]uril‐Encapsulation‐Controlled Supramolecular Photoproduct and Radical Fluorescence Emission
Authors: Peng Min , Luo Yi , Rao Yutao , Song Jianxin , Ni Xin‐Long 
Published: September 2022

AbstractHerein, a host–guest interaction–controlled photoproduct created by using cucurbit[7]uril (Q[7])‐based pseudorotaxane structures is reported. The assembly exhibited controlled behavior towards the reduction of the ethylene (C=C) bond in the tetrakis(pyridin‐4‐yl)ethylene (TPyE) guest molecule under UV light irradiation. This can be attributed to the Q[7] encapsulation masking the four pyridinium arms of the guest, which inhibits planarization of the TPyE core to form the cyclization product. In particular, the strong affinity of Q[7] for the butyl‐substituted guest (TPyE‐4C) led to an unusual radical fluorescence emission of the photoirradiation‐triggered intermediate of the guest molecule being observed in aqueous solution. This work provides a valuable paradigm and new insight for macrocycle‐based host−guest interactions in supramolecular catalysis and luminescent radical materials.
1,2,5‐Triarylcycloalka[c]arsoles: Structural Effects of Fused‐cycloalkanes on Stability and Photophysical Properties
Authors: Iwasaki Suzuka , Miyake Yusuke , Imoto Hiroaki , Naka Kensuke 
Published: September 2022

AbstractHerein, we have synthesized a variety of cycloalkane‐fused arsoles. Cyclopentane and cyclohexane were incorporated into the cycloalkane‐fused arsoles. Surprisingly, cyclohexane‐fused arsole 2 a gradually decomposed via oxidative ring‐opening under ambient conditions, while cyclopentane‐fused 1 a was stable. In addition, the Stokes shift of 2 a (7766 cm−1) is larger than that of 1 a (5120 cm−1). The effects of the fused cycloalkane on the stability and photophysical properties were attributed to the distortion of the cycloalkane. Computational calculations demonstrated that the cyclohexane moiety in 2 a was frustrated upon being incorporated into the rigid arsole ring, while the cyclopentane moiety in 1 a was much less distorted.
Shedding Light on the Enigmatic TcO2 ⋅ xH2O Structure with Density Functional Theory and EXAFS Spectroscopy**
Authors: Oliveira Augusto F. , Kuc Agnieszka , Heine Thomas , Abram Ulrich , Scheinost Andreas C. 
Published: September 2022

AbstractThe β‐emitting 99Tc isotope is a high‐yield fission product in 235U and 239Pu nuclear reactors, raising special concern in nuclear waste management due to its long half‐life and the high mobility of pertechnetate (TcO4−). Under the conditions of deep nuclear waste repositories, Tc is retained through biotic and abiotic reduction of TcO4− to compounds like amorphous TcO2 ⋅ xH2O precipitates. It is generally accepted that these precipitates have linear (Tc(μ‐O)2(H2O)2)n chains, with trans H2O. Although corresponding Tc−Tc and Tc−O distances have been obtained from extended X‐ray absorption fine structure (EXAFS) spectroscopy, this structure is largely based on analogy with other compounds. Here, we combine density‐functional theory with EXAFS measurements of fresh and aged samples to show that, instead, TcO2 ⋅ xH2O forms zigzag chains that undergo a slow aging process whereby they combine to form longer chains and, later, a tridimensional structure that might lead to a new TcO2 polymorph.
