AbstractOrientational control of anisotropic plasmonic nanoparticles is an attractive proposition to generate dynamic plasmonic responses. Particularly, the use of light as a stimulus to modulate the orientation is extremely useful owing to its spatiotemporal operative ability. This work showcases a light‐mediated approach to tune the orientational features of gold nanorods in DNA‐engineered hydrogel materials. The strategy relies on the use of visible‐light‐induced photothermal effects to cause deformation of the hydrogel matrix, resulting in temperature‐controlled polarization‐dependent optical responses whose anisotropy features are highly adaptive to the nature of DNA crosslinks. The visible‐light‐mediated approach showcased here can open novel avenues to create dynamic light‐responsive materials with reconfigurable plasmonic responses.

AbstractMetallic zinc as a promising anode material of aqueous zinc ion batteries is always impeded by some irreversible issues, such as dendrite growth, hydrogen evolution, and parasitic reaction, which severely affect the cycling stability and coulombic efficiency. Herein, the membrane of SO42‐ receptors is constructed on the Zn anode (denoted SO42‐ receptors as SR). The SR acts as a sulfate ion receptor to capture SO42‐, the resulting negatively charged coating can effectively disperses Zn2+ to promote uniform deposition and enhance Zn2+ mobility to stabilize high‐current cycling, while the repulsion of free SO42‐ coupled with high Gibbs free energy for hydrogen evolution reaction (ΔGH*) of SR and SR‐SO42‐ can effectively suppress the formation of parasitic (ZnSO4)·(Zn(OH)2)3∙xH2O. Benefiting from this versatility, Zn anode can achieve an average coulombic efficiency of over 99% and superior cycling performance (10 000 cycles for 10mA cm‐2 and 450 cycles for 5 mAh cm‐2). Meanwhile, Zn@SR/α‐MnO2 full battery can maintain 91.7% residual capacity after 900 cycles under 1.0 A g‐1.

AbstractThe construction of organelle‐targeting nanomaterials is an effective way to improve tumor imaging and treatment. Here, a new type of composite nanomaterial named as PTTPB is developed. PTTPB is composed of organelle‐targeting aggregation‐induced emission photosensitizer TTPB and polydopamine nanomaterials. With the functional modification of TTPB, PTTPB can recognize sialic acid on the cell membrane and present mitochondrial targeted capabilities. The intake of PTTPB in cancerous cells can be increased by the recognition process of cell membrane. PTTPB can generate singlet oxygen for photodynamic therapy (PDT), and present good photothermal conversion ability with irradiation. The PTTPB with organelle‐targeting imaging‐guided can realize the tumor ablation with the synergistic effect of PDT and photothermal therapy.

AbstractNanowire lasers are potential light sources that can be used in photonic integrated circuits (PICs) for inter‐chip optical communication. However, due to the size incompatibility between a nanoscale laser and a micrometer‐scale optical waveguide, their integration within a PIC remains challenging. Here, an in situ growth strategy to directly construct perovskite nanolasers inside the long polymethyl methacrylate (PMMA) fibers is explored. As the perovskite nanolasers are embedded inside the PMMA fibers, effective coupling of lasing light to the PMMA fibers is expected. Furthermore, due to the protection of PMMA coating, the perovskite nanolasers exhibit high robustness in water and demonstrate significant improvement in photostability. Stable single‐mode and polarization operations are obtained at room temperature from the lasers with a low excitation threshold. Hence, these results pave the way to realize ultra‐stable perovskite‐based PICs suitable for inter‐chip optical communication.

AbstractThe precursor conversion chemistry and surface chemistry of Cu3N and Cu3PdN nanocrystals are unknown or contested. Here, we first obtain phase‐pure, colloidally stable nanocubes. Second, we elucidate the pathway by which copper(II) nitrate and oleylamine form Cu3N. We find that oleylamine is both a reductant and a nitrogen source. Oleylamine is oxidized by nitrate to a primary aldimine, which reacts further with excess oleylamine to a secondary aldimine, eliminating ammonia. Ammonia reacts with CuI to form Cu3N. Third, we investigated the surface chemistry and find a mixed ligand shell of aliphatic amines and carboxylates (formed in situ). While the carboxylates appear tightly bound, the amines are easily desorbed from the surface. Finally, we show that doping with palladium decreases the band gap and the material becomes semi‐metallic. These results bring insight into the chemistry of metal nitrides and might help the development of other metal nitride nanocrystals.

Abstract

The middle part of the Sava River in Slovenia provides one of the longest free‐flowing habitats for huchen, a threatened species that is also protected by the European Habitats Directive. However, there are plans for the construction of a chain of hydropower plants along this stretch of river. It has previously been assumed that huchen is no longer self‐sustainable here, but dependent upon stocking with hatchery‐reared fish.
Using microsatellite and mitochondrial DNA, the genetic structure of huchen in its entire range in Slovenia was analysed with the particular aim of assessing the self‐sustainability of the species in the middle Sava.
Using factorial correspondence analysis and assignment tests, a distinct genetic cluster was identified for each of the three main river systems in the country (Sava, Kolpa and Mura–Drava). In the middle Sava, a genetic admixture between stocked and local individuals, observed beyond F1, and a unique genetic substructure not corresponding to the stocking sources, were found.
These results indicate the self‐sustainability of the middle Sava population and justify its protection. The estimated effective population size in the middle Sava is below the accepted minimum, and additional fragmentation arising from dam construction would cause the genetic breakdown of this huchen population.
To preserve local genetic pools and possible inter‐population adaptive differentiation, we recommend that the three, historically isolated, river system‐bound populations (from the Sava, Kolpa and Mura–Drava) are managed separately. However, separate management of the small, isolated populations in the once free‐flowing Sava river system is not encouraged as it may cause their genetic impoverishment.
The potential impact of this study on the conservation management of huchen more widely is discussed, with emphasis on the Balkans, where large populations still exist and their management is just beginning.
Dynamic Stereochemistry of a Biphenyl‐Bisprolineamide Model Catalyst and its Imidazolidinone Intermediates

Published: May 2022

AbstractIn this study, we characterize the dynamic stereochemistry of a biphenyl‐2,2’‐bis(proline amide) catalyst in chloroform and DMSO as representative weakly and strongly hydrogen bonding solvents. Using vibrational circular dichroism (VCD) spectroscopy and density functional theory (DFT) based spectra calculations, we show that the preferred axial stereochemistry of the catalyst is determined by solute‐solvent interactions. Explicitly considering solvation with DMSO molecules is found to be essential to correctly predict the conformational preferences of the catalyst. Furthermore, we investigate the stereochemistry of the corresponding enamines and imidazolidinones that are formed upon reaction with isovaleraldehyde. The enamines are found to rapidly convert to endo‐imidazolidinones and the thermodynamically favored exo‐imidazolidinones are formed only slowly. The present study demonstrates that the stereochemistry of these imidazolidinones can be deduced directly from the VCD spectra analysis without any further detailed analysis of NMR spectra. Hence, we herein exemplify the use of VCD spectroscopy for an in situ characterization of intermediates relevant in asymmetric catalysts.

AbstractA general copper‐catalyzed carbonylative cross‐coupling between amines and alkyl iodides is reported. Using a simple combination of catalytic amounts of copper(I) chloride andN,N,N’,N”,N”‐pentamethyldiethylenetriamine in the presence of sodium hydroxide under carbon monoxide pressure, a broad range of alkyl iodides and amines can be efficiently coupled to the corresponding amides that are obtained in good to excellent yields. Notable features of this process – the first one relying on a base metal catalyst – include the availability and low cost of the catalytic system, its successful use with primary, secondary, tertiary alkyl iodides and all classes of amines – with no or limited competing nucleophilic substitution without CO incorporation – as well as its efficiency with complex alkyl iodides and amines. Mechanistic studies demonstrated that a radical pathway is operative and the key role of CO.

Abstract3D Porous carbon‐based materials are well known for their excellent mechanical and electrochemical properties for various energy storage applications including Li‐ion Battery (LIB) anodes. However, their commercial application is limited due to their low theoretical specific capacity. Heteroatom doping in carbonaceous networks proved an efficient way to modify the surface properties, which considerably improves the Li intake capacity and Li diffusion in porous carbon materials. In this work, we have synthesized 3D honeycomb boron carbon nitride (HBCN) from boric acid, glucose, and cyanamide. Silica nanoparticles (SiO2 NPs) are used as structure‐directing agents to replicate well‐organized honeycomb structures. HBCN possesses a high specific surface area (SSA) of ∼597 m2 g−1, with a uniform porosity distribution, low charge transfer resistance, and steady Li flux. When analyzed as an anode material for LIB, HBCN demonstrated an excellent specific capacity of ∼652 mAhg−1 and 408 mAhg−1 at an input current density of 100 mAg−1 and 1 Ag−1 respectively and an energy density of 227 Wh kg−1 at 1 C rate in a full cell LIB. These results indicate that the doping of B and N hetero atoms is significantly advantageous for LIBs application.

AbstractMolecular solar thermal (MOST) systems are a promising approach for the introduction of sustainable energy storage solutions. We investigated the feasibility of the dicyano‐substituted norbornadiene/quadricyclane molecule pair on Ni(111) for catalytic model studies. This derivatization is known to lead to a desired bathochromic shift of the absorption maximum of the parent compound. In our experiments further favorable properties were found: At low temperatures, both molecules adsorb intact without any dissociation. In situ temperature‐programmed HR‐XPS experiments reveal the conversion of (CN)2‐quadricyclane to (CN)2‐norbornadiene under energy release between 175 and 260 K. The absence of other surface species due to side reactions indicates full isomerization. Further heating leads to the decomposition of the molecular framework into smaller carbonaceous fragments above 290 K and finally to amorphous structures, carbide and nitride above 400 K. DFT calculations gave insights into the adsorption geometries. (CN)2‐norbornadiene is expected to interact stronger with the surface, with flat configurations being favorable. (CN)2‐quadricyclane exhibits smaller adsorption energies with negligible differences for flat and side‐on geometries. Simulated XP spectra are in good agreement with experimental findings further supporting the specific spectroscopic fingerprints for both valence isomers.

Published: May 2022

AbstractDifferent populations of immune cells rely on their distinct migration patterns for immunosurveillance, immune regulation, tissue specific differentiation, and maturation. It is often important to clarify whether cells are recirculating or tissue resident, or whether tissue‐specific cells are derived from blood‐borne precursors or a tissue‐resident population. Though migration or tissue residency of immune cells critically depends on the expression of different homing molecules (chemokine receptors, tissue retention molecules, etc.), characterization based solely on the expression of homing molecules may not faithfully reflect the migration patterns of immune cells. Therefore, a more reliable method to clarify migration patterns of immune cells is required. Parabiosis is a surgical connection of two mice resulting in a shared circulatory system, which allows reliable distinction of tissue‐resident and circulating cells. Here, we describe a set of protocols for parabiosis, including technique details, pitfalls, and suggestions for optimization and troubleshooting. © 2022 Wiley Periodicals LLC.Basic Protocol 1: Preparation of mice for parabiosis surgeryBasic Protocol 2: Parabiosis surgeryBasic Protocol 3: Recovery and use of mice after parabiosis surgeryBasic Protocol 4: Reversal of parabiotic surgeryBasic Protocol 5: Analysis of parabionts
An approach of data analysis to improve scheduling efficiency in optical burst switched networks
Authors: Nhat Vo Viet Minh , Hoa Le Van 
Published: May 2022

SummaryScheduling at the core node plays an important role in the transmission performance of optical burst switched (OBS) networks. There are two approaches of scheduling for an incoming burst: with void filling and without void filling, where the scheduling with void filling is more efficient thanks to the ability to exploit the idle bandwidth between scheduled bursts. However, the scheduling success depends on factors such as arrival time, burst length, last available unused time (LAUT), void start time, void end time, and so forth. This paper proposes a scheduling data analysis approach to find the factors that influence scheduling efficiency, thereby suggesting an FDL‐based solution to reduce data loss. The results of analysis and simulation show that the derived factors including the last overlap and the near‐last overlap have the most significant influence on the scheduling success rate and the FDL‐based solution is best suited for loss reduction.

Abstract2‐Methylmercaptobenzohydroxamic acid (mmbHA) has been synthesized and used to form {CuIICl2(MeOH)[12‐MCCu(II)N(mmbHA)‐4]}2 ⋅ 4MeOH (1) and {CuII(μ2‐ClO4)(MeOH)2(py)4[12‐MCCu(II)N(mmbHA)‐4]}ClO4 (2), a copper(II) based double‐decker and a discrete metallacrown (MC) system, respectively. While 1 forms in the absence of a coordinating co‐ligand, the presence of pyridine (Py) leads to a change in the coordination mode of mmbHA and a discrete MC 2 is formed. Both compounds have been structurally and magnetically characterized. The magnetic susceptibility measured from 2–300 K shows overall antiferromagnetic exchange coupling within both crown structures and the obtained coupling constants are J1=−88.0(1) cm−1and J2=−64.7(3) cm−1 for 1 and J1=−90.0(5) cm−1 and J2=−31.1(1) cm−1 for 2. However, the ratio of the coupling parameters is highly affected by the structural change.

AbstractBackgroundIn March 2020, state‐wide lockdowns were declared in many countries, including Spain. Citizens were confined to their homes and remotely supported activities were prioritized as an alternative to in‐person interactions. Previous data suggest that remote and self‐management interventions may be successful at reducing pain and related psychological variables. However, individual factors influencing the effectiveness of these interventions remain to be identified. We aimed to investigate the psychological and motivational factors moderating changes in pain observed in chiropractic patients undertaking a novel telehealth self‐management programme.MethodsA cohort of 208 patients from a chiropractic teaching clinic was recruited to participate in the study. Patients received telehealth consultations and individualized self‐management strategies tailored for their current complaint. They were encouraged to make use of these strategies daily for 2–4 weeks, whilst rating their pain intensity, motivation and adherence. Validated questionnaires were completed online to assess catastrophizing, kinesiophobia and anxiety.ResultsA total of 168 patients completed the first 2 weeks of the programme, experiencing significant reductions in all variables. Kinesiophobia emerged as a key factor influencing pain reduction and moderating the association between motivation and pain relief. In turn, adherence to the programme was associated with lower pain intensity, although moderated by the degree of motivation.ConclusionsIn the context of COVID‐19, when introducing remote and self‐management strategies, pain cognitions and motivational factors should be taken into consideration to foster adherence and yield better pain outcomes.

AbstractWearable sensing devices have transformed the hourly analysis of events such as body signals and environmental risks into real‐time monitoring in minutes or seconds. Wearable sensors have facilitated the ability to obtain useful data by monitoring the physiological parameters and activities of an aided and a healthy individual. Wearable devices employ detectable biomarkers in the human body, such as in tears, saliva, interstitial fluid, sweat, and so on. These can deliver relevant information on human health, online activity monitoring, and therapeutic treatments. This section outlines the significance of sample types and associated biomarkers as indicators in the development and manufacturing of wearable biosensors. We have emphasized the most recent advances of wearables based on skin‐like and textile, giving attention to personalized health monitoring to record signals of motion and physiological and body fluid investigation. Furthermore, this review categorizes wearable biosensors based on the sensing mechanism, electrochemical, optical, and mechanical. Additionally, the recent wearables related to the detection of the newly havoc‐causing pandemic, COVID‐19, and the future perspective for the development of much more advanced and potent wearable biosensors have been highlighted. The final section highlights unmet difficulties and gaps in wearable sensors in personalized therapy.

Published: May 2022

AbstractThe phytostabilization of acid mine spoil by industrially important aromatic crops could be a sustainable solution with minimum input for the problem associated with acidic mine spoil‐affected areas. In the present study, the suitability of Pelargonium graveolens for phytostabilization of acidic mine spoil has been investigated in three different combinations (T1: 100% soil; T2: 100% mine spoil, T3: 75 mine spoil: 25 soil and T4: 50 mine spoil: 50 soil). The plant growth performance, metal accumulation, ecological indices, soil properties, enzymes, and microbial diversity along with the identification of dominant bacterial isolates were investigated in the study. The results indicated that mine spoil was highly acidic (pH 3.01) and rich in minerals and toxic metals. The values of the tolerance index and oil content of P. graveolens L under different treatments varied from 43% to 89% and from 0.10 to 0.13% without affecting oil quality, respectively. Bio‐concentration (BCF) and translocation factor (TF) indicated that the P. graveolens can be used as a phyto‐excluder for Al, Fe, Cr, Zn, and Pb and phytoextractor for Cu, Ni, and Mn. The plantation of P. graveolens enhanced the microbial biomass and enzymatic activities of soil and immobilized the metals. The increase in the Shannon index from 1.67–1.86 to 1.9–2.61 suggested enhanced bacterial diversity after plantation. The identify bacterial isolates were metal tolerant and plant growth promoters. The study suggested that P. graveolens is suitable for the phytostabilization purpose of acidic mine spoils along with the economic return.
