AbstractPhotoresponsivity is a fundamental process that constitutes optoelectronic devices. In molecular junction devices, one of the most adopted strategies is to employ photoactive molecules that can undergo conformational change upon light illumination as the conduction channel. However, such devices suffer from their relatively low photoresponsivity, long switching time, and unidirectional switching. In this study, the authors employed organohalide perovskite (OHP)/graphene heterojunction as a photoactive electrode that acted a source of photo‐generated carriers collected as photocurrent in self‐assembled monolayer (SAM)‐based molecular junctions. This hybrid device architecture of perovskite/graphene/SAM allows the molecular junctions to attain a high photoresponsivity with molecules that have intrinsically little photoresponse. The authors elucidate the role of the molecular SAM in enhancing the photoresponsivity by systematically examining the transport and charge transfer processes at the graphene/SAM interface via molecules with different intrinsic dipole moments. This, corroborated with a theoretical analysis, reveals the origin of the observed photoresponsivity as light‐induced coupling between the SAM and the OHP/graphene electrode within the orbital‐mediated resonant tunnelling transport regime. These findings advance the understanding of photo‐induced charge transport in molecular junctions with heterointerfaces, providing a road‐map for designing high‐performance molecular optoelectronic devices based on hybrid device architecture.

Published: April 2022

AbstractTerahertz waves have widespread applications in various fields ranging from wireless communication to fundamental physics. Achieving bright and broadband terahertz sources still remains a challenge. Recent research has revealed that all‐dielectric metasurfaces with strong electromagnetic resonances and negligible Ohmic loss can enhance nonlinear optical processes and weaken the influences of phase‐matching conditions, providing new opportunities for developing terahertz sources. Here, an all‐dielectric metasurface supporting quasi‐BIC (bound states in the continuum), which enhances terahertz emission in a nonlinear optical film under the excitation of femtosecond laser pulses, is proposed. It is observed that the terahertz emission in lithium niobate (LiNbO3) films is enhanced up to 17 times by a silicon dioxide metasurface and that the terahertz emission enhancement spans the frequency range in 0.1–4.5 THz. This mechanism for the terahertz emission enhancement is attributed to the tight confinement of the pump field in the LNibO3 which is caused by quasi‐BIC resonances. The all‐dielectric metasurface is patterned on the LiNbO3 film instead of etching it, providing a simple way for engineering nonlinear optical processes in LiNbO3. This work paves the way for broadband terahertz emitters.

AbstractVisible‐to‐near‐infrared organic photodetectors (vis–NIR OPDs) are highly desired due to their potential applications in both scientific research and industry. To develop state‐of‐the‐art diode‐type OPDs, general strategies aiming to reduce the dark current density (Jd) involve reducing the thickness of the bulk‐heterojunction (BHJ) active layer, but this simultaneously leads to a sharp drop in photoresponse. Herein, a facile fabrication strategy, i.e., thermally induced anti‐aggregation (TIAA) evolution strategy, is introduced for manipulating the phase separation scale and molecular arrangement orientation of the PBDB‐T:Y6 based active layer. To a typical 500 nm‐thick BHJ, much higher and balanced electron/hole mobilities are achieved through the TIAA manipulation. By effectively equilibrating the Jd (8.7 × 10‐8 A cm‐2) and responsibility (0.5 A W‐1 at 860 nm), the optimized vis–NIR OPD showcases high specific detection of over 1012 Jones (380–940 nm) and capability of faint IR light detection (≈10‐10 W cm‐2 at 850 nm) at −0.5 V bias. Meanwhile, the device displays the ability to monitor pulse signal in real time through photoplethysmography, indicating the potential of TIAA evolution strategy to fabricate high‐performance vis–NIR OPDs for next‐generation wearable health monitoring.

AbstractCadmium‐based nanoplatelets as optical display and lasing materials are widely explored and exhibit great advantages, owing to their narrow emission linewidths, anisotropic transition‐dipole distributions, and low lasing thresholds. However, in the green range, the photoluminescence quantum yield (PLQY) and emission tunability of nanoplatelets are still inferior to that of quantum dots. In this work, a new synthesis protocol is developed, enabling core/crown nanoplatelets to grow continuously from elementary precursors to their final form. A new heterostructure of CdSe/CdSeS core/alloyed‐crown nanoplatelets is produced that realizes 100% PLQY, the continuous tunability of emission peaks in between 502 and 550 nm, and low full‐width‐at‐half‐maximum (FWHM) of less than 15 nm. Achieving these excellent properties in all three aspects at the same time is unprecedented. In addition, the time‐resolved photoluminescence (TRPL) spectra of these nanoplatelets show a mono‐exponential decay characteristic, and the nanoplatelet film can also show 100% PLQY and a mono‐exponential decay characteristic, indicating the suppression of trap states. The high‐quality nanoplatelets achieved in this work provide a solid foundation for developing nanoplatelet‐based light sources, like light‐emitting diodes and lasers, with much higher efficiency, color purity, and lower working thresholds.
Programmable Bidirectional Mechanical Metamaterial with Tunable Stiffness and Frictional Energy Dissipation

Published: April 2022

AbstractEnergy‐dissipating mechanical metamaterials possess broad applications where absorbing shocks and isolating vibrations within monolithic and sandwich composite structures are required. This study presents the design of a novel bidirectional mechanical metamaterial with tunable stiffness and energy dissipation. By leveraging the phenomenon of Coulomb friction, the metamaterial dissipates energy when a small gap closes and two walls slide across one another under planar loading. The conceptual design of the metamaterial is parameterized, so the material behavior can be tailored to a particular application. A computational framework is built, using finite element analysis and a multi‐objective genetic algorithm to maximize the volumetric energy dissipation such that the unit cell does not undergo plastic deformation. The finite element mesh used in this analysis is first parametrically optimized to minimize simulation time while remaining within a global error threshold. The optimal unit cell is arrayed into a bulk material, formed into a hollow cylinder, and simulated under a compression cycle for different metamaterial densities. A prototype of the hollow cylinder is 3D printed via fused deposition modeling and is tested. Both the simulated and experimental results demonstrate the repeatability of the energy‐dissipating property with a strong correlation.

AbstractReplacing oxygen evolution reaction (OER) by electrooxidations of organic compounds has been considered as a promising approach to enhance the energy conversion efficiency of the electrolytic water splitting proces. Developing efficient electrocatalysts with low potentials and high current densities is crucial for the large‐scale productions of H2 and other value‐added chemicals. Herein, non‐noble metal electrocatalysts Co‐doped Ni3S2 self‐supported on a Ni foam (NF) substrate are prepared and used as catalysts for 5‐hydroxymethylfurfural (HMF) oxidation reaction (HMFOR) under alkaline aqueous conditions. For HMFOR, the Co0.4NiS@NF electode achieves an extremely low onset potential of 0.9 V versus reversible hydrogen electrode (RHE) and records a large current density of 497 mA cm–2 at 1.45 V versus RHE for HMFOR. During the HMFOR‐assisted H2 production, the yield rates of 2,5‐furandicarboxylic acid (FDCA) and H2 in a 10 mL electrolyte containing 10 × 10−3 M HMF are 330.4 µmol cm–2 h–1 and 1000 µmol cm–2 h–1, respectively. The Co0.4NiS@NF electrocatalyst displays a good cycling durability toward HMFOR and can be used for the electrooxidation of other biomass‐derived chemicals. The findings present a facile route based on heteroatom doping to fabricate high‐performance catalyses that can facilitate the industrial‐level H2 production by coupling the conventional HER cathodic processes with HMFOR.

AbstractGiven coronavirus 2019 (COVID‐19), we empirically investigate whether consumers are willing to pay for greater sustainability and safer working conditions in food supply chains. We elicit consumer valuation via two consumer choice survey experiments and revealed preferences using mixed Logit discrete choice models. We find that consumers have a significant positive average valuation towards sustainability, but may require an average compensation to choose products produced under safer working conditions. Policy implications suggest a market‐based potential to nudge consumer segments who desire value congruence in their diet, namely, by revealing information through labeling.

Published: April 2022

AbstractRealizing high energy‐density and actual applications of fibre‐based electrochemical supercapacitors (FESCs) are pivotal but challenging, as the ability to construct advanced fibres for accelerating charges kinetic diffusion and Faradaic storage remain key bottlenecks. Here, we demonstrate high‐performance FESCs based on hetero‐structured polymetallic oxides/porous graphene core–sheath fibres, where the large pseudo‐active polymetallic oxide (PMO) sheath is uniformly loaded on a hierarchical porous graphene fibre (PGF) core. Due to the abundant micro‐/mesoporous pathways, large accessible surface, excellent redox activity and good interface electron conduction, the PMO‐PGF possesses high areal capacitance (2959.78 mF cm−2) and manageable Faradaic reversibility in a 6 M KOH electrolyte. Furthermore, the PMO‐PGF‐based solid‐state FESCs present high energy‐density (187.22 μ Wh cm−2), long‐life cycles (95.8 % capacitive retention after 20 000 cycles), diverse‐powered capabilities and actual energy‐supply applications.

Published: April 2022

AbstractHigh‐performance adhesives are of great interest in view of industrial demand. We herein identify a straightforward synthetic strategy towards universal hydrogen‐bonded (H‐bonded) polymeric adhesives, using a side‐chain barbiturate (Ba) and Hamilton wedge (HW) functionalized copolymer. Starting from a rubbery copolymer containing thiolactone derivatives, Ba and HW moieties are tethered as pendant groups via an efficient one‐pot two‐step amine‐thiol‐bromo conjugation. Hetero‐complementary Ba/HW interactions thus yield H‐bonded supramolecular polymeric networks. In addition to an enhanced polymeric network integrity induced by specific Ba/HW association, the presence of individual Ba or HW moieties enables strong binding to a range of substrates, outstanding compared to commercial glues and reported adhesives.

AbstractA family of fully sandwichedarachno‐lanthanacarborane complexes formulated as {η6‐[μ‐1,2‐[o‐C6H4(CH2)2]‐1,2‐C2B10H10]2Ln}{Li5(THF)10} (Ln=Tb, Dy, Ho, Er, Y) is successfully synthesized, where the “carbons‐adjacent” carboranyl ligand (arachno‐R2‐C2B10H104−) bears four negative charges and coordinates to the central lanthanide ions using the hexagonal η6C2B4face. Thus, the central lanthanide cations are pseudo‐twelve‐coordinate and have an approximate pseudo‐D6hsymmetry or hexagonal‐prismatic geometry. As the crystal field effect imparted by this geometry is still unknown, we thoroughly investigated the magnetic properties of this series of complexes and found that the crystal field imposed by this ligand causes a relation of Tb>Dy>Ho>Er for the energy gaps between the ground and the first excited states, which is of striking resemblance to the ferrocenophane and phthalocyanine ligands although the latter two ligands give disparate local coordination geometries. Moreover, the effective energy barrier to magnetization reversal of 445(10) K, the observable hysteresis loop up to 4 K and the relaxation time of the yttrium‐diluted sample reaching 193(17) seconds at 2 K under an optimized field for the Tb analogue of this family ofarachno‐lanthanacarborane complexes, render a new benchmark for Tb3+‐based single‐molecule magnets.
Bonding in a Crystalline Tri‐Thorium Cluster: Not σ‐Aromatic But Still Unique
Authors: Szczepanik Dariusz W. 
Published: April 2022

AbstractVery recently, Boronski et al. reported the first thorium–thorium bond in a crystalline cluster prepared under normal experimental conditions. By using a range of experimental techniques and computational models, the authors found that the isolated actinide cluster contains at its heart two paired electrons delocalized over the tri‐thorium ring. The recorded Raman spectrum allegedly confirmed the existence of a σ‐aromatic three‐center two‐electron bond. In the following we demonstrate that the experimentally observed broad inelastic scattering bands between 60 and 135 cm−1, originally assigned by the authors to thorium‐thorium vibrations, represent the combination of Th−Cl stretching and Th−Cl−Th bending modes, and they establish the existence of an unprecedented multicenter charge‐shift bonding (ThCl2)3 rather than the σ‐aromatic bonding Th3. In the light of the presented findings, the latter remains experimentally unproven and computationally questionable.

AbstractBackgroundThe THOC6 protein is a component of the THO complex. It is involved in mRNA transcription, processing and nuclear export. Interestingly molecular biallelic loss‐of‐function variants of the THOC6 gene were identified in the Beaulieu–Boycott–Innes syndrome (BBIS– OMIM # 613680). This condition was described in 17 patients and is characterized by a moderate to severe intellectual disability, facial dysmorphic features and severe birth defects such as heart, skeletal, ano‐genital and renal congenital malformations.MethodsIn the present study, we report on a new family with two affected sibs. The 6‐year‐old female had severe intellectual disability with autistic features, feeding difficulties, growth delay, facial dysmorphic, and congenital malformations (hand, skeletal and cardiac anomalies). The male fetus presented antenatally with a cystic hygroma associated with severe aortic and left ventricular hypoplasia. Autopsy, after termination of pregnancy at 15 weeks of gestation, showed facial dysmorphic, short right thumb and hypospadias.ResultsExome sequencing detected in both sibs compound heterozygous variants of the THOC6 gene (NM_024339.3, GRCh37): the already reported c.[298T>A;700G>T;824G>A] haplotype and a novel variant c.977T>G, p.(Val326Gly).DiscussionWe made a review of the literature of 17 BBIS reported patients including our two siblings. Severe to moderate ID and congenital malformations were constant. Prenatal and postnatal failure to thrive were frequent. Brain MRI were not specific. Prenatal findings were reported in 40% of cases but we described the first case of cystic hygroma. The present study reports extends the prenatal delineation of the phenotypic features observed in association with the presence of THOC6 variants. In addition, it underscores the intrafamilial phenotypic variability observed in BBIS.

Published: April 2022

AbstractBackgroundHead and neck squamous cell carcinoma (HNSCC) is the sixth most common malignant tumor worldwide with high morbidity and mortality. However, the diagnosis and molecular mechanisms of HNSCC remains poor.MethodsRobust rank aggregation method was performed to excavate the differentially expressed genes (DEGs) in five datasets (GSE6631, GSE13601, GSE23036, GSE30784, GSE107591) from the Gene Expression Omnibus. Search Tool for the Retrieval of Interacting Genes (STRING) database extracted hub genes from the protein‐protein interaction network. The expression of the hub genes was validated using expression profile from The Cancer Genome Atlas and Oncomine database. The module analysis and disease‐free survival analysis of the hub genes were analyzed by Cytoscape and the Kaplan‐Meier curve, respectively. The expression of hub genes was verified in clinical specimens. The functions of MMP1 which is most important in hub genes were explored in vitro and in vivo.ResultsTotally, 235 DEGs were identified in the present study which consists of 103 up‐regulated and 132 down‐regulated genes which were significantly enriched in the molecular function of calcium ion binding followed in the biological process of skin development. The mainly enriched pathways were ECM (extracellular matrix)‐receptor interaction (hsa04512) and protein digestion and absorption (hsa04974). Six hub genes were screened out which showed dramatically increased expression in HNSCC samples compared with normal samples, including COL4A1, MMP1, PLAU, RBP1, SEMA3C, and COL4A2. These hub genes all showed worse disease‐free survival with higher expression and were up‐regulated in HNSCC clinical samples. MMP1 was proved to promote cell growth, migration, and phosphorylation of AKT in vitro and to promote liver metastasis in vivo.ConclusionBioinformatics analysis identified six key genes in HNSCC. Of these, MMP1 is the most likely biomarker. It activates the AKT pathway and promotes tumor progression.

AbstractCytochrome P450 enzymes (CYPs or P450s) are ubiquitous heme‐dependent enzymes that catalyze the monooxygenation of non‐activated C−H bonds to modify the structure of the substrate. In this study, we heterologously expressed CYP107X1 from Streptomyces avermitilis and conducted in vitro substrate screening using the alternative redox partners putidaredoxin and putidaredoxin reductase. CYP107X1 catalyzed the 16α‐hydroxylation of progesterone with regio‐ and stereoselectivity. The spectroscopic analyses showed that CYP107X1 bound progesterone with a relatively high Kd value of 65.3±38.9 μM. The Km and kcat values for progesterone were estimated to be 47.7±12.0 μM and 0.30 min−1, respectively. Furthermore, a crystal structure was obtained of CYP107X1 bound with glycerol from the buffer solution. Interestingly, a conserved threonine was replaced with asparagine in CYP107X1, indicating that it may adopt an unnatural proton transfer process and play a crucial role in its catalytic activity.

AbstractSchwannoma is a type of nerve tumor of the nerve sheath. They are preferentially localized on the head, neck, and flexor surfaces of the extremities. Retroperitoneal schwannoma is extremely rare. The diagnosis is uncommon and based on the anatomopathological and immunochemistry examination of the surgical specimen. We herein report an uncommon location of schwannoma treated with conventional surgery in a 53‐year‐old female patient admitted to our department for chronic abdominal pain. Retroperitoneal schwannoma is a rare disease that occurs in adult females. The histopathological examination is the only reliable examination for the diagnosis after total surgical resection.
