Wearable, Implantable, Parity‐Time Symmetric Bioresonators for Extremely Small Biological Signal Monitoring
Authors: Takamatsu Taiki , Sijie Yin , Miyake Takeo 
Published: April 2023

AbstractWireless biosensors are essential for digital transformations in health and medicine. Chipless resonant antenna‐based biosensors are affordable and tractable but are unsuitable for practical use because the common wireless sensing systems have low sensitivity caused by low quality factors. Herein, a parity‐time (PT) symmetric wireless biosensor is demonstrated that can detect small biological signals such as tear glucose level (0.1–0.6 mm) for diabetes diagnosis and blood lactate level (0.0–4.0 mm) for lactic acidosis diagnosis. The characteristics of the PT‐symmetric wireless sensing system are modeled by using an eigenvalue solution and input impedance, and the sensitivity enhancement at/near the exceptional point by using parallel inductance–capacitance–resistance resonators is experimentally demonstrated. 2000 times higher sensitivity for linear detection and 78% relative change for threshold‐based detection are achieved. Furthermore, the proposed PT‐symmetric wireless sensing system has sufficient tunability and robustness for use as a wearable/implantable device for monitoring small biological signals.

AbstractMagnetic metamaterials have demonstrated promising perspectives to improve the efficiency of magnetic flux concentrators. In this work, the effects of downscaling these devices for on‐chip integration is investigated. The influence of the non‐linear magnetic response of the ferromagnetic components, their magnetic irreversibility, the formation of magnetic domains, as well as the effects of geometry and size of the devices are scrutinized. The results demonstrate that the implementation of metasurfaces at the microscale opens up new technological possibilities for enhancing the performance of magnetic field detectors and remotely charging small electric devices, thus paving the way toward new approaches in information and communication technologies.

Published: April 2023

AbstractTetradentate Pt(II) complex (Pt‐Trz)‐sensitized green fluorescent organic light‐emitting‐diodes (OLEDs) are developed to improve the external quantum efficiency (EQE) of a green fluorescent emitter (PhtBuPAD). Pt(II) complex and a green fluorescent emitter with bulky blocking units are chosen to efficiently manage energy transfer in phosphor‐sensitized OLEDs. The Pt‐Trz phosphor‐sensitized fluorescent OLED with 2 wt% PhtBuPAD exhibits high EQE of 24.2% and maintains high EQE of 23.4% at a luminance of 3000 cd m−2, realizing low efficiency roll‐off of 3.8%. Moreover, high EQE is achieved even at a high PhtBuPAD‐doping concentration of 3 wt%. In addition, the 2 wt% PhtBuPAD‐doped phosphor‐sensitized device achieves high maximum power efficiency of 91.1 lm W−1, one of the highest power efficiencies among existing green sensitized devices. This study demonstrates that Pt‐Trz phosphor‐sensitized devices with an excellent triplet exciton utilization ability can achieve high EQE, low efficiency roll‐off, and weak doping concentration quenching simultaneously.

Published: April 2023

AbstractTransition metal dichalcogenides (TMDCs) have various electronic and optical properties depending on their structure, so they can be used as a fascinating material in various applications including photonics, electronics, optoelectronics, and valleytronics. In particular, spiral TMDCs grown through the formation of screw dislocations exhibit novel electronic and optical properties different from layer‐by‐layer TMDCs. However, large‐area structure‐selective synthesis of TMDCs remains challenging. Here, this work reports for the first time the large‐area structure‐selective synthesis of monolayer MoSe2 and spiral MoSe2 using a flux‐controlled chemical vapor deposition method. Under a low MoSe2 flux condition, monolayer MoSe2 is synthesized, whereas thick spiral MoSe2 is synthesized under a high flux condition. Under a medium flux condition, both monolayer and spiral MoSe2 are synthesized. In addition, through the nonlinear optical (NLO) signal analysis of monolayer MoSe2 and spiral MoSe2, the giant enhancement of NLO signals induced by the combined effect of breaking inversion symmetry and the excitonic resonance effects in the synthesized MoSe2 is confirmed. Monolayer MoSe2 and spiral MoSe2 synthesized using this method are expected to be used as advanced optical materials for novel electronics, optoelectronics, and NLO applications.

Published: April 2023

AbstractCircularly polarized emission (CPE) has attracted great interest in optoelectronics, biosensing, etc. Here, a resonant planar chiral dielectric metasurface that can be constructed to provide a preferable way for CPE is demonstrated. The planar metasurface is easy to fabricate, and the corresponding far‐field circular polarization degree is extremely high and angle‐insensitive. The designed metasurface is made of a periodic array of in‐plane mirror‐asymmetric silicon pillar dimers and supports a low‐leakage chiral band‐edge mode. Experimentally, the photoluminescence of a thin film of PbS/CdS quantum dots coated on such a metasurface is enhanced by 57 times with the far‐field degree of circular polarization as high as 0.74. The planar platform provides a flexible and efficient way for manipulating CPE, in which other periodic coupling effects may also be adopted to enhance the light–matter interaction, such as quasi‐bound states in the continuum and lattice resonance.

AbstractThe catalyst‐controlled diversity‐oriented synthesis of spirohydroquinoline‐indandiones and 3‐methylenehydroquinoline‐indandiones from ortho‐sulfonamidophenyl‐substituted para‐quinone methides and allylidene‐indandiones is reported. The strategies utilized an organobase such as DMAP or TMG to control the reaction pathway chemoselectively, furnishing the corresponding products in 40–99% yields with excellent diastereoselectivities. The mechanistic studies revealed that spirohydroquinoline‐indandione was the kinetic product to afford 3‐methylenehydroquinoline‐indandione in the presence of TMG, which probably involved an unusual base‐initiated 1,3‐nitrogen rearrangement process.magnified image

Published: April 2023

AbstractIn guided bone regeneration surgery, a barrier membrane is usually used to inhibit soft tissue from interfering with osteogenesis. However, current barrier membranes usually fail to resist the impact of external forces on bone‐augmented region, thus causing severe displacement of membranes and their underlying bone graft materials, eventually leading to unsatisfied bone augmentation. Herein, a new class of local double‐layered adhesive barrier membranes (ABMs) is developed to successfully immobilize bone graft materials. The air‐dried adhesive hydrogel layers with suction‐adhesion properties enable ABMs to firmly adhere to the wet bone surface through a “stick‐and‐use” band‐aid‐like strategy and effectively prevent the displacement of membranes and the leakage of bone grafts in uncontained bone defect treatment. Furthermore, the strategy is versatile for preparing diverse adhesive barrier membranes and immobilizing different bone graft materials for various surgical regions. By establishing such a continuous barrier for the bone graft material, this strategy may open a novel avenue for designing the next‐generation barrier membranes.

Published: April 2023

AbstractMetal phthalocyanine (Pc) complexes are considered to be promising functional organic materials owing to their tunable properties and unique π‐electron structure. Despite these advantages, the application of polymeric metal Pc into lithium–sulfur (LiS) batteries has yet to be explored. Herein, this work demonstrates a molecular design of multifunctional polymeric cobalt Pc with triethylene glycol linkers (TCP) that provide a redox mediating capability for the Co ion in the center of the Pc, a strong polar interaction of N atoms with Li, and the lithiophilic sites of crown ether mimicking linkers for highly efficient LiS batteries. As verified by electrochemical and theoretical analyses, the cooperative redox mediating and lithiophilic effects of TCP coated onto multiwalled carbon nanotube (TCP/MC) are attributed to the facilitated conversion reaction kinetics of S cathodes for the high utilization efficiency of S and the inhibition of polysulfide shuttling. Consequently, the S@TCP/MC delivers high discharge capacity of 1392.8 mA h g−1 and high‐rate capacity of 667.9 mA h g−1 at 5.0 C. Moreover, this cathode achieves a high capacity retention of 81.5% over 200 cycles, along with a high areal capacity of 6.83 mA h cm−2 at 0.2 C with a high S loading of 6.6 mg cm−2.

AbstractPoor interfacial contacts of Li mental/solid‐state electrolytes (SSEs) cause high impedance and induce lithium dendrite growth, which hinders the practical viability of solid‐state batteries (SSBs). Optimizing the surface chemistry of SSEs has been widely adopted for improving the Li/SSE interfacial contact. Their surface's microstructure, another critical factor influencing the actual performance of SSBs, however, has seldom been paid attention to; and the corresponding mechanism remains unclear. Addressing this issue, the authors herein propose a “surface microstructure optimization” strategy that can significantly enhance the Li/SSE interfacial contact, and in the meantime, quantify the correlations between SSB's performance and SSE's surface roughness regarding the interfacial resistance, current focusing, critical current density (CCD), and lithium deposition. Based on these fundamental understandings, a low‐surface‐roughness SSE is developed, which shows extremely small interfacial impedance (1.7 Ω cm2) and ultra‐long stable cycling life (4500 h at 0.2 mA cm−2). This work not only comprehensively demonstrates the fundamental relationship between the surface microstructure of SSEs and their battery performance but also presents a new insight into the modulation of surface kinetics of ceramic SSEs toward achieving dendrite‐free SSBs.

AbstractHigh‐voltage lithium metal batteries are the most promising energy storage technology due to their excellent energy density (>400 Wh kg−1). However, the oxidation decomposition of conventional carbonate‐based electrolytes at the high‐potential cathode, the detrimental reaction between the lithium anode and electrolyte, particularly the uncontrolled lithium dendrite growth, always lead to a severe capacity decay and/or flammable safety issues, hindering their practical applications. Herein, a solvation structure engineering strategy based on tuning intermolecular interactions is proposed as a strategy to design a novel nonflammable fluorinated electrolyte. Using this approach, this work shows superior cycling stability in a wide temperature range (−40 °C to 60 °C) for a 4.4 V‐class LiNi0.8Co0.1Mn0.1O2 (NCM811)‐based Li‐metal battery. By coupling the high‐loading of NCM811 cathode (3.0 mAh cm−2) and a controlled amount of lithium anode (twofold excess of Li deposition on Cu, Cu@Li) (N/P = 2), the Cu@Li || NCM811 full cell can cycle more than 162 cycles with high‐capacity retention of 80%. This work finds that the change of the coordination environment of Li+ with solvent and PF6− by tuning intermolecular interaction is an effective method to stabilize the electrolyte and electrode performance. These discoveries can provide a pathway for electrolyte design in metal ion batteries.

Published: April 2023

AbstractPolicy responses to slow the spread of COVID‐19 have increased economic insecurity globally. We use panel data collected immediately before and during the COVID‐19 pandemic with adolescents in Bangladesh to assess the association between COVID‐19‐related restrictions and adolescent hunger. One year into the pandemic, adolescents were three‐fold more likely to report hunger, and households were twice as likely to report cutting back food to adolescents compared to before COVID‐19 restrictions. Vulnerable households experienced larger increases in hunger and reductions in food consumption, with girls more adversely affected than boys. Cash and food aid were unable to mitigate these negative trends.

AbstractAutosomal recessive microcephaly and chorioretinopathy‐1 (MCCRP1) is a rare Mendelian disorder resulting from biallelic loss of function variants in Tubulin‐Gamma Complex Associated Protein 6 (TUBGCP6, MIM#610053). Clinical features of this disorder include microcephaly, cognitive impairment, dysmorphic features, and variable ophthalmological anomalies including chorioretinopathy. Microcephaly can be recognized prenatally and visual impairment becomes evident during the first year of life. The clinical presentation resembles the findings in some acquired conditions such as congenital toxoplasmosis and cytomegalovirus infections; thus, it is important to recognize and diagnose this syndrome in view of its impact on patient health management and familial reproductive plans. To date, only seven molecularly confirmed patients from five unrelated families have been reported. We report an additional four unrelated patients with TUBGCP6 variants including one prenatal diagnosis and review the clinical phenotypes and genotypes of all the known cases. This report expands the molecular and phenotypic spectrum of TUBGCP6 and includes additional prenatal findings associated with MCCRP1.

AbstractAbout 100 genes have been associated with cardiomyopathies with genotype–phenotype correlations often hard to establish. Genetic testing may help to confirm the genetic diagnosis and assess the risk of inheritance in the family. A 25‐year old male with hypertrophic cardiomyopathy and fasciculoventricular accessory pathway was referred for genetic testing by his cardiologist. Targeted PRKAG2 screening and whole‐exome sequencing were performed, followed by Sanger sequencing segregation analysis in the family. The PRKAG2 gene screening was negative. Whole‐exome sequencing revealed the following four variants in the patient: c.181G>C (p.Ala61Pro) and c.1199C>T (p.Thr400Met) in the GTPBP3 gene, as well as c.752C>T (p.Thr251Ile) and c.1760C>T (p.Pro587Leu) in the POLG gene. Family segregation analysis showed that the patient's mother is a carrier of variant c.181G>C and the patient's paternal grandmother is a carrier of variant c.1199C>T in the GTPBP3 gene, which is in accordance with an autosomal recessive model of inheritance of the disease. Both variants in the POLG are found paternally inherited in the patient's healthy half‐brother, thus are not considered disease‐causing. GTPBP3 variants have been reported in patients with hypertrophic cardiomyopathy, associated with combined oxidative phosphorylation deficiency 23. These novel variants represent the probable cause of the observed clinical symptoms in the patient.

AbstractNanofluidic reverse electrodialysis provides an attractive way to harvest osmotic energy. However, most attention was paid to monotonous membrane structure optimization to promote selective ion transport, while the role of external fields and relevant mechanisms are rarely explored. Here, we demonstrate a Kevlar‐toughened tungsten disulfide (WS2) composite membrane with bioinspired serosa‐mimetic structures as an efficient osmotic energy generator coupling light. As a result, the output power could be up to 16.43 W m−2 under irradiation, outperforming traditional two‐dimensional (2D) membranes. Both the experiment and simulation uncover that the generated photothermal and photoelectronic effects could synergistically promote the confined ion transport process. In addition, this membrane also possesses great anti‐fouling properties, endowing its practical application. This work paves new avenues for sustainable power generation by coupling solar energy.

Published: April 2023

AbstractA long neck is an evolutionary innovation convergently appearing in multiple tetrapod lineages, including groups of plesiosaurs, non‐archosauriform archosauromorphs, turtles, sauropodomorphs, birds, and mammals. Among all tetrapods both extant and extinct, two Triassic archosauromorphs,TanystropheusandDinocephalosaurus, have necks that are particularly elongated relative to the lengths of their trunks. However, the evolutionary history of such hyper‐elongated necks in these two archosauromorph clades remains unknown, partially because known close relatives such asMacrocnemusandPectodenspossess only moderately elongated necks. Here, we describe a newly discovered early diverging archosauromorph,Gracilicollum latensgen. et sp. nov., based on a specimen comprising a partial neck and an incompletely preserved skull. The long neck is composed of at least 18 cervical vertebrae. The dentition suggests that this new taxon most likely represents an aquatic piscivore, similar toDinocephalosaurusandTanystropheus hydroides. Despite possessing a high number of cervical vertebrae,Gracilicollumgen. nov. is recovered as a tanystropheid in an evolutionary grade betweenMacrocnemusandTanystropheusrather than as a close relative ofDinocephalosaurus, a result that is primarily attributable to the presence of palatal teeth and the anatomy of the cervical vertebrae inGracilicollumgen. nov. Considering the information provided by the new specimen, we provide a detailed discussion of the cervical evolution in dinocephalosaurids and tanystropheids, which is shown to be highly complex and mosaic in nature.

AbstractTumor is one of the leading causes of death in children (0 to 14‐year‐old) and adolescents (15 to 19‐year‐old) worldwide. Unlike adult tumors, childhood and adolescent tumors are unique in their type, molecular characteristics, and pathogenesis, and their treatment involves many challenges. In recent years, with the development of a large number of clinical studies, the survival rate of children and adolescents with tumors has improved significantly. The extensive research and application of optimized treatment regimens and new targeted drugs have led to new hope for the treatment of childhood and adolescent tumors. This article reviews the clinical and basic research and treatment of childhood and adolescent tumors and provides new ideas for the future development of precise treatment of childhood and adolescent tumors.
