Authors: Cai Suzhi , An Zhongfu , Huang Wei 
Published: September 2022

AbstractHydrogen‐bonded organic frameworks (HOFs) have aroused interest due to their applications in gas storage and separation and proton conduction. Much effort has been focused on developing stable HOFs with permanent porosity. Recently, more attention has been paid to the development of luminescent HOFs. At present, a systematic study on luminescent HOFs is lacking. Here, recent advances in luminescent HOFs are highlighted. The construction of luminescent HOFs, luminescent properties of HOFs, and corresponding applications are discussed in detail. According to luminescent properties, luminescent HOFs can be divided into fluorescent HOFs and room‐temperature phosphorescent HOFs. In addition, HOFs with color‐tunable luminescence, stimuli‐responsive luminescence, or mechanoluminescence are also introduced at great length. These distinctive features endow HOFs with wide applications in chemical sensing, microlasers, stimuli‐responsive sensing, oxygen sensing, data encryption, and so on. This review not only provides the basic principle of designing luminescent HOFs but also points out the research perspectives of luminescent HOFs in the future. This review lays the foundation for developing luminescent HOFs, thus broadening the applications of HOFs and enriching luminescent porous materials.

AbstractAnode‐free Li metal batteries are one of the finest prospects for increasing energy density beyond that of standard lithium‐ion batteries. Conversely, the absence of Li reservoir generates unwarranted volume expansion, permitting electrolyte depletion and rapid cathode capacity consumption. To address this issue, an anode‐free Li metal battery with an ion‐conductive layer coated Cu current collector Ag/L in typical carbonate‐based electrolytes is presented. The ion‐conducting layer causes stable solid electrolyte interphase development and allows for minimal volume expansion when utilizing stable Li hosts. Via density functional theory calculation and experimental measurements and analysis, the beneficial effect of Li hosting behavior of the ion‐conductive layer is demonstrated. Furthermore, anode‐free electrochemical performance with high discharge capacity retention, which is exceptional in a traditional carbonate electrolyte with LiNi0.8Mn0.1Co0.1O2 based cathode (4.2 mAh cm−2) and high current density (2.1 mA cm−2) is shown. To prove material compatibility, argyrodite sulfide solid electrolytes instead of liquid electrolytes, which show Coulombic efficiency of 97% at 50 cycles in all‐solid‐state Li half‐cells are used.

AbstractThe combination of photothermal therapy (PTT) and chemotherapy is considered a promising tumor treatment modality, nevertheless, cellular resistance induced by heat shock proteins (HSPs) overexpressed in tumor cells will restrict the therapeutic effect. Herein, a multifunctional nanobeacon DOX/HCuS@PDA‐MB (D/CP‐MB) with a scout function for HSP90 mRNA fluorescence detection and near‐infrared (NIR) triggered drug release for sensitizing chemo–photothermal therapy, is proposed. In the theranostic nanobeacons, HSP90MBs not only enable fluorescence detection of intracellular HSP90 mRNAs, but also downregulate the expression of HSP90 to reduce cell resistance. With the assistance of NIR and guidance of fluorescence imaging, spatiotemporal doxorubicin release can be achieved by the trigger of the photothermal effect, allowing for combined chemotherapy and photothermal treatment. Furthermore, the dual photothermal effect of hollow mesoporous CuS (HCuS) and polydopamine will lead to a better photothermal effect. Moreover, compared with other control groups, D/CP‐MB nanobeacons exhibit effective boost therapeutic efficacy by inducing significant suppression of tumor proliferation and enhancement of apoptosis both in vitro and in vivo. In summary, this work provides novel theranostic nanobeacons that integrate imaging and therapy in a single nanoparticle, this strategy of imaging‐guided therapy can enable precise tumor treatment and effectively improve tumor treatment efficacy.

AbstractInorganic 2D layered CsPbI3 is awaiting to overcome the phase instability of traditional 3D components. However, the most reported Ruddlesden–Popper (RP) phase 2D CsPbI3 leads to larger interlayer distance and weaker interlayer coupling since the existence of the van der Waals gap, which deteriorates the performance of the device and makes the improvement of stability unsatisfactory. Herein, this work resorts ethylenediamine cations (EDA2+) to construct a series of Dion–Jacobson (DJ) phase 2D CsPbI3 as (EDA)Csn−1PbnI3n+1 with van der Waals gap eliminated. Combining simulation calculations and experiments, it is found that the (EDA)Csn−1PbnI3n+1 has enhanced intermolecular forces to overcome the problem of insufficient crystallization power caused by large steric hindrance in the film assembly process compared to phenethylammonium‐based RP phase analogues. In addition, profit from the reduced interlayer distance and stronger coupling, the rigidity of the structure is increased, and the annoying non‐radiative recombination caused by structural fluctuations is alleviated. As a result, the 2D layered DJ phase CsPbI3‐based solar cells deliver eminent performance than RP phase analogues, especially the 2D (EDA)(Cs)4Pb5I16 (n = 5) device exhibits a record PCE of 10.43% in this work, and significantly enhanced stability.

AbstractNatural wind energy harvesting enables a far‐reaching and sustainable solution to supply pervasive sensors in the Internet of Things (IoT). Electromagnetic generators (EMGs) struggle to harvest energy from breezes, which causes regrettable energy wastage. Herein, a triboelectric‐electromagnetic hybridized nanogenerator (TEHG) is designed with a dual‐rotor structure to consolidate harvesting band for high efficiency of triboelectric nanogenerators (TENGs) in breeze and the EMG in high wind speeds. The TEHG performs an efficient energy collection (41.05 W m−3) and a smooth output in the wind speed of 2−16 m s−1, attributed to the environmental self‐adaptive cooperation between TENGs and EMGs. The TENG output power contribution is more than 70% at low wind speeds (<5 m s−1). Moreover, a dual‐channel power management topology (DcPMT) is established to co‐manage outputs of two modules in TEHG. By virtue of the DcPMT hierarchically combining the isolated storage with undervoltagelockout strategy, the TEHG steadily supplies a standardized 3.3 V voltage for commercial electronics. Furthermore, a TEHG‐based self‐powered system is demonstrated for driving sensors to monitor meteorological information. The TEHG with DcPMT is advantageous in broad‐band and high‐efficiency of wind energy harvesting, thus exhibiting a great potential for elevating the environmental self‐adaptability and stability margin of the IoT.

Published: September 2022

AbstractBackgroundComputed tomography (CT) and magnetic resonance (MR) represent the gold standard for evaluating intracranial tumours, such as meningiomas; most meningiomas can be managed by surveillance and clinical follow‐up, therefore, the ideal technology should be cheap, non‐invasive, safe and able to reduce radiation exposure. Transcranial colour‐coded duplex sonography (TCCS) can detect space‐occupying lesions, but its full potential for clinical practice is still unexpressed.Aims and MethodsWe describe the ability of TCCS to directly and accurately image, in a 77‐year‐old woman hospitalised for septic shock and coma, a suprasellar meningioma with a spatial resolution very similar to CT.ResultsThe meningioma was clearly visualised as a roundish mass, with well‐defined borders, heterogeneously hyperechogenic compared with the surrounding brain structures; multiple intralesional calcifications were detectable as highly echogenic spots. Latero‐lateral and antero‐posterior diameters were well measurable.DiscussionTCCS should not be considered as an alternative to CT and MR imaging, but it might have a complementary role, useful for use at the bedside in uncooperative or non‐transportable patients and for follow‐up, when an adequate acoustic window is guaranteed. Neurologists and neuroradiologists should further explore the full potential of this technology.

Published: September 2022

AbstractMotivated by the exciting prediction of multi‐Weyl topological semimetals stabilized by point group symmetries, tunneling in anisotropic multi‐Weyl semimetals is studied. It is found that distant detectors for different ranges of an anisotropy parameter λ and incident angle θ will measure different numbers of propagating transmitted modes. These findings are presented as phase diagrams that are valid for incoming waves with fixed wavenumber k. Energy is not held fixed for incoming waves but allowed to vary with choice of incident angle and wavenumber k. To gain a deeper understanding of this phenomenon they focus on the simplest case of anisotropic quadratic Weyl‐semimetals and tunneling coefficients are analyzed analytically and numerically to confirm observations extracted from phase diagrams. Results show nonanalytical behavior, which is the hallmark of phase transitions. This serves as motivation to make a formal analogy with phase transitions known from statistical mechanics. Specifically, they argued that the long distance limit in the tunneling problem mimics the thermodynamic limit in statistical mechanics. A direct formal connection is found to the recently developed formalism of dynamical phase transitions. They propose that usage of this analogy with dynamical phase transitions can be fruitful in classifying transport properties of exotic semimetals.

Published: September 2022

AbstractCovalent organic frameworks (COFs) are an emerging category of organic polymers with highly porous crystalline structures. In the last decade, reports on the use of COFs as heterogeneous photocatalysts for organic transformations have shown significant progress. Still, comprehensive reviews on the mechanisms of the photocatalytic organic transformations using COFs are lacking. This Review provides a comprehensive and systematic overview of COF‐based photocatalysts for organic transformations. Firstly, we discuss the photophysical properties and the characterization methods of COF‐based photocatalysts. Then, the general photocatalytic mechanism, the advantages, and the strategies to improve the photocatalytic efficiency of COF‐based photocatalysts are summarized. After that, advanced examples of COF‐based photocatalysts for organic transformations are analyzed with regard to the underlying mechanisms. The Review ends with a critical perspective on the challenges and prospects.
Microbial Fermentation of Polyethylene Terephthalate (PET) Plastic Waste for the Production of Chemicals or Electricity**
Authors: Kalathil Shafeer , Miller Melanie , Reisner Erwin 
Published: September 2022

AbstractIdeonella sakaiensis (I. sakaiensis) can grow on polyethylene terephthalate (PET) as the major carbon and energy source. Previous work has shown that PET conversion in the presence of oxygen released carbon dioxide and water while yielding adenosine triphosphate (ATP) through oxidative phosphorylation. This study demonstrates that I. sakaiensis is a facultative anaerobe that ferments PET to the feedstock chemicals acetate and ethanol in the absence of oxygen. In addition to PET, the pure monomer ethylene glycol (EG), the intermediate product ethanol, and the carbohydrate fermentation test substance maltose can also serve as fermenting substrates. Co‐culturing of I. sakaiensis with the electrogenic and acetate‐consuming Geobacter sulfurreducens produced electricity from PET or EG. This newly identified plastic fermentation process by I. sakaiensis provides thus a novel biosynthetic route to produce high‐value chemicals or electricity from plastic waste streams.

Published: September 2022

AbstractAn efficient catalytic asymmetric [2+2] cycloaddition of allenyl imide and mono‐ or disubstituted alkenes is disclosed. The key feature of this method is the use of bidentate allenyl imide and weakly activated and less steric hindered alkene pair by utilizing chiral magnesium(II) complex of N,N′‐dioxide, which could provide through‐space dispersion interactions to orientate the arrangement of the alkene. This protocol allows the generation of a series of axially chiral cyclobutenes and four‐membered ring‐containing spirocycles (80 examples) in high yield (up to 99 %) with excellent enantioselectivity (up to >99 % ee), and the late‐stage modification of biologically active molecules as well. Experimental studies and DFT calculations revealed that this [2+2] cycloaddition proceeded via a stepwise mechanism involving a short‐lived zwitterionic intermediate. The π‐π interaction between the alkenes and the amide moiety in the ligand was crucial for the enantiocontrol.

Published: September 2022

AbstractLeuco dye‐based thermochromic materials offer enormous potential for visible molecular logic due to the appealing reversible color‐changing effect. The stable color state is uncontrollable as it depends only on the spontaneous protonation of the leuco dye and color developer. There is still a challenge to propose an effective approach to control bistable color function at required temperature. A family of azobenzenes with various alkyl chains (AZO(n)) is designed for protonation competition with leuco dye. The hydrogen bond and Van der Waals forces are formed between color developer and AZO(n). The color developer can be locked to provide the proton for the leuco dye by Z‐AZO(n), while it can be released upon Z‐to‐E photoisomerization. The locked state can be lasted for more than 16 hours. This optically controlled leuco dye‐based system demonstrates a visible sequential logic operation with four‐input signals, and provides a new type of protonation‐based optical control.

AbstractClass III lanthipeptide synthetases catalyze the formation of lanthionine/methyllanthionine and labionin crosslinks. We present here the 2.40 Å resolution structure of the kinase domain of a class III lanthipeptide synthetase CurKC from the biosynthesis of curvopeptin. A unique structural subunit for leader binding, named leader recognition domain (LRD), was identified. The LRD of CurKC is responsible for the recognition of the leader peptide and for mediating interactions between the lyase and kinase domains. LRDs are highly conserved among the kinase domains of class III and class IV lanthipeptide synthetases. The discovery of LRDs provides insight into the substrate recognition and domain organization in multidomain lanthipeptide synthetases.

Published: September 2022

AbstractHollow fiber membranes have higher surface area and are easy to be applied in systems. Because of theirs self‐supporting construction, they have limited mechanical durability. By reinforcing these membranes with a braid, the mechanical strength can be improved. In this study, the impact of polyvinyl pyrrolidone (PVP) as a pore‐forming additive with different contents on the fabrication of polysulfone braid reinforced hollow fiber membranes was investigated both as a ultrafiltration membrane and as a support for the fabrication of thin film composite (TFC) nanofiltration membranes. Characterization and filtration studies of all membranes were performed to examine membrane performance. It was discovered that the porosity and hydrophilicity of the ultrafiltration membranes were enhanced by enhancing PVP concentration, thus increasing the pure water flux in the membranes. As regards to results of fabricated TFC membranes, salt rejections were increased with increasing PVP ratios. The rejection efficiency of magnesium sulfate and sodium chloride was found to be approximately 80% and 49%, respectively, when a PVP ratio of 8% was used.

AbstractDespite the rapid progress of organic electronics, developing high‐performance n‐type organic semiconductors is still challenging. Donor‐acceptor (D‐A) type conjugated structures have been an effective molecular design strategy to achieve chemically‐stable semiconductors and the appropriate choice of the acceptor units determines the electronic properties and device performances. We have now synthesized two types of A1‐D‐A2‐D‐A1 type conjugated molecules, namely, NDI‐BTT‐NDI and NDI‐TBZT‐NDI, with different central acceptor units. In order to investigate the effects of the central acceptor units on the charge‐transporting properties, organic field‐effect transistors (OFETs) were fabricated. NDI‐TBZT‐NDI had shallower HOMO and deeper LUMO levels than NDI‐BTT‐NDI. Hence, the facilitated charge injection resulted in ambipolar transistor performances with the optimized hole and electron mobilities of 0.00134 and 0.151 cm2 V−1 s−1, respectively. In contrast, NDI‐BTT‐NDI displayed only an n‐channel OFET performance with the electron mobility of 0.0288 cm2 V−1 s−1. In addition, the device based on NDI‐TBZT‐NDI showed a superior air stability to that based on NDI‐BTT‐NDI. The difference in these OFET performances was reasonably explained by the contact resistance and film morphology. Overall, this study demonstrated that the TBZ acceptor is a promising building block to create n‐type organic semiconductors.

AbstractBackgroundDespite the fact that the father contributes half the genome to a child, associations between paternal factors and birth defects are poorly understood.ObjectivesTo investigate the association between preconception paternal health and birth defects in the offspring.Materials and MethodsWe conducted analysis of a national cohort study utilizing the IBM Marketscan Research Database, which includes data on reimbursed private healthcare claims in the United States from 2007 to 2016. The potential association between paternal comorbidities, as measured by the components of metabolic syndrome (MetS), and any birth defect in the offspring was analyzed.ResultsOf the 712,774 live births identified, 21.2% of children were born to fathers with at least one component of the metabolic syndrome (MetS ≥1) prior to conception. Compared to infants born to fathers with no components of the metabolic syndrome, a modestly higher percentage of infants with cardiac birth defects were born to fathers with more components of MetS (MetS = 1, OR [95% CI]: 1.07 [1.01–1.13]; MetS ≥2, 1.17 [1.08–1.26], in comparison to MetS = 0) after adjusting for maternal and paternal factors. Similarly, a higher percentage of infants with respiratory defects were born to fathers with two or more components of metabolic syndrome (MetS ≥2, OR [95% CI]: 1.45 [1.22–1.71]).Discussion and ConclusionIn this private insurance claims‐based study, we found that fathers with metabolic syndrome‐related diseases before conception were at increased risk for having a child affected by birth defects, especially cardiac and respiratory defects, and this association was not influenced by paternal age or assessed maternal factors.

AbstractDie ÖBB‐Infrastruktur AG baut die Position der Bahn als eines der umweltfreundlichsten Verkehrsmittel kontinuierlich aus. Zu einem nachhaltigen Angebot für Mobilität und Logistik gehört vor allem auch der Ausbau einer leistungsfähigen Schienennetzinfrastruktur. Auf der Strecke Linz–Selzthal wird in den nächsten Jahren ein selektiver zweigleisiger Ausbau vorgenommen, dessen Kernstück im Bereich der oberösterreichischen Pyhrnbahn zwischen Hinterstoder und Vorderstoder/Pießling auf einer 8,5 km langen Trassenneulage basiert. Bereits in den Vorplanungen zum UVP‐Verfahren sind wesentliche Aspekte einer nachhaltigen und dauerhaften Streckenverfügbarkeit vorweggenommen. Insbesondere auch im Bereich der Brückenbauwerke werden Sonderwege beschritten, die in deutlicher Weise diese Streckenverfügbarkeit und Langlebigkeit der Bauwerke sicherstellen sollen. Auf dem genannten Streckenabschnitt werden neben mehreren kleineren zweigleisigen Brückenbauwerken die großen, derzeit eingleisigen Talbrücken erneuert. Geplant sind drei Bogenbrücken und zwei Balkenbrücken, deren Besonderheiten dieser Bericht genauer beschreibt. Dabei geht es vor allem um Themen wie Möglichkeiten zur späteren halbseitigen Erneuerung, Lasterhöhung, nachträgliche Vorspannung sowie Sonderwege bei Gleis‐Tragwerk‐Interaktion und Bremslasten auf den neuen, nun zweigleisigen Brücken. Diese besonderen Planungsrandbedingungen wurden bereits zur UVP‐Einreichung auf Niveau eines Ausschreibungsprojekts behandelt.
