EnantioselectivePhotolysis and Quantitative Chiral Analysis of Tryptophan Complexed With Alkali‐Metalized L‐Serine in the Gas Phase
Authors: Fujihara Akimasa , Maeda Naoto , Hayakawa Shigeo
Published: April 2015

The enantioselective photolysis of a cold gas‐phase noncovalent complex of tryptophan with alkali‐metalized L‐serine, M+(L‐Ser)(Trp) (M = Na and Li), was examined using a tandem mass spectrometer containing a variable‐temperature ion trap. CO2 loss from Trp in the clusters was enantiomerically selective in ultraviolet excitation with linearly polarized light. M+(L‐Ser) promoted the enantioselective photolysis of Trp as a chiral auxiliary. The enantioselective photolysis of the D‐enantiomer was applied to a quantitative chiral analysis, in which the optical purity of tryptophan could be determined by measuring the relative abundance ratio R of the enantioselective CO2 loss to the chiral‐independent evaporation of L‐Ser in a single photodissociation mass spectrum of M+(L‐Ser)(Trp).

NIR Fluorogenic Dye as a Modular Platform for Prodrug Assembly: Real‐Time in vivo Monitoring of Drug Release
Authors: Redy‐Keisar Orit , Ferber Shiran , Satchi‐Fainaro Ronit , Shabat Doron
Published: April 2015

The ability to monitor drug release in vivo provides essential pharmacological information. We developed a new modular approach for the preparation of theranostic prodrugs with a turn‐ON near‐infrared (NIR) fluorescence mode of action. The prodrugs release their chemotherapeutic cargo and an active cyanine fluorophore upon reaction with a specific analyte. The prodrug platform is based on the fluorogenic dye QCy7; upon removal of a triggering substrate, the dye fluoresces, and the free drug is released. The evaluated camptothecin prodrug was activated by endogenous hydrogen peroxide produced in tumor cells in vitro and in vivo. Drug release and in vitro cytotoxicity were correlated with the emitted fluorescence. The prodrug activation was effectively imaged in real time in mice bearing tumors. The modular design of the QCy7 fluorogenic platform should allow the preparation of numerous other prodrugs with various triggering substrates and chemotherapeutic agents. We anticipate that the development of real‐time in vivo monitoring tools such as that described herein will pave the way for personalized therapy.
Bis(benzoyloxybenzyl)‐DiPPro Nucleoside Diphosphates of Anti‐HIV Active Nucleoside Analogues
Authors: Weinschenk Lina , Gollnest Tristan , Schols Dominique , Balzarini Jan , Meier Chris
Published: April 2015

Nucleoside analogues are extensively used as antiviral and anticancer agents. Their efficiency is dependent on their metabolism into the ultimately active nucleoside triphosphates. Often one step or even more in the metabolism of the nucleoside to the triphosphate is inefficient. To overcome this hurdle, prodrugs of the nucleotides are needed. Bis(acyloxybenzyl)nucleoside diphosphates have been reported by us as a first example of an efficient nucleoside diphosphate prodrug (DiPPro nucleotides). Here, the synthesis and the properties of bis(benzoyloxybenzyl)nucleoside diphosphates of the nucleoside analogues d4T and AZT are disclosed. The synthesis was achieved by using a phosphoramidite/oxidation route. In chemical hydrolysis studies, most of the compounds formed a nucleoside diphosphate. This was confirmed in CEM cell extracts, although the prodrug stability in extracts was lower than in phosphate buffer. Furthermore, the stability and the amount of nucleoside diphosphate formed were dependent on the substituent in the benzoyl moiety. Some of the compounds were more active against HIV in thymidine kinase‐deficient CEM/TK− cells than were d4T or AZT.

Renal function in survivors of nonsyndromic Wilms tumor treated with unilateral radical nephrectomy
Authors: Interiano Rodrigo B. , Delos Santos Noel , Huang Sujuan , Srivastava Deo Kumar , Robison Leslie L. , Hudson Melissa M. , Green Daniel M. , Davidoff Andrew M.
Published: April 2015

BACKGROUND

Partial nephrectomy is considered by some for children with unilateral Wilms tumor (UWT) to avoid the theoretical complication of renal insufficiency. In the current study, the authors evaluated the prevalence of hypertension and impaired renal function in long‐term survivors of nonsyndromic UWT who were treated without nephrotoxic chemotherapy or ionizing radiation.

METHODS

Eligibility included age ≤15 years at the time of diagnosis of nonsyndromic UWT, treatment receipt before 2002, and maintenance of disease remission after unilateral nephrectomy without receipt of abdominal irradiation or nephrotoxic chemotherapy. Renal function was assessed by urinalysis and estimated glomerular filtration rate (eGFR). Patients receiving antihypertensive medication or those with blood pressure readings of >140/90 mm Hg were considered to be hypertensive.

RESULTS

A total of 75 patients with a median age at diagnosis of 3.2 years (range, 0.2‐12.1 years) met eligibility criteria. The median length of follow‐up was 19.6 years (range, 10.0‐32.8 years). All but 1 patient had stage I/II disease. Sixty‐eight patients (90.7%) patients had WT with favorable histology and 7 patients had anaplastic histology. Sixteen patients (21.3%) had an eGFR <90 mL/minute/1.73m2, 2 of whom also had proteinuria (12.5%). No patient had an eGFR <60 mL/minute/1.73m2. Five patients (6.7%) had hypertension, 3 of whom were receiving antihypertensive medications. At the time of last follow‐up, no patient had developed end‐stage renal disease.

CONCLUSIONS

Patients with UWT who were treated with unilateral radical nephrectomy without nephrotoxic chemotherapy or ionizing radiation appear to be at low risk of developing significant long‐term renal dysfunction. For this patient population, the routine use of partial nephrectomy does not appear justified. However, monitoring and counseling are important for identifying the rare patient who develops subtle renal insufficiency and therefore might be at an increased risk of adverse cardiovascular sequelae.

SDIVIP2: shared data integrity verification with identity privacy preserving in mobile clouds
Authors: Yu Yong , Ni Jianbing , Xia Qi , Wang Xiaofen , Yang Haomiao , Zhang Xiaosong
Published: April 2015

Mobile networks integrate cloud computing to impair the weaknesses of the mobile terminals. With mobile cloud storage, mobile users can fully enjoy the advantages from both mobile networks and cloud storage. However, a major concern of mobile users is how to guarantee the integrity of their outsourced data. Taking into account the mobility of mobile devices, in this paper, we propose a shared data integrity verification protocol with identity privacy preserving, named SDIVIP2, for mobile cloud storage. In the construction of SDIVIP2, the dynamic group key agreement technique is employed for key sharing among a group of mobile users and the proxy re‐signature mechanism is utilized to update tags efficiently when users in the group change. In this new protocol, a third party auditor is able to verify the correctness of cloud data without the knowledge of mobile users' identities during the data integrity checking process. Performance analysis demonstrates that SDIVIP2 outperforms the existing schemes in the sense that it can significantly enhance the efficiency of mobile users' joining and leaving a group.

Modulation of Electron Injection Dynamics of Ru‐Based Dye/TiO2 System in the Presence of Three Different Organic Solvents: Role of Solvent Dipole Moment and Donor Number
Authors: Mahanta Subrata , Matsuzaki Hiroyuki , Murakami Takurou N. , Katoh Ryuzi , Matsumoto Hajime , Furube Akihiro
Published: April 2015

In the present work, femtosecond transient absorption spectroscopy (fs‐TAS) has been employed to investigate the electron injection efficiency (EIE) both from the singlet and triplet excited states of a well‐known ruthenium dye (N719) to the conduction band (CB) of nanostructured TiO2 in presence of three different organic solvents [γ‐butylactone (GBL), 3‐methoxypropionitrile (MPN), and dimethylformamide (DMF)] with different donor numbers (DNs) and dipole moments (DMs). The DM and DN of a solvent modulates the CB edge energy of TiO2, and this effect reflects well in the fs‐TAS results, which shows an EIE trend following the order GBL≥MPN≫DMF, that is, highest in GBL and lowest in DMF solvent environments. Fs‐TAS results indicate a lower contribution of electron injection from both the singlet and triplet states in DMF, for which the dominant adsorption of DMF molecules on the TiO2 surface seems to play an important role in the mechanism.
Investigation of Thermodynamic, Dynamic, and Structural Properties of H2 Adsorption on a Ag–Au Nanoalloy with a Carbon Nanotube Support
Authors: Akbarzadeh Hamed , Abbaspour Mohsen , Salemi Sirous , Dastoorani Mahmood
Published: April 2015

We have performed MD simulations to investigate H2 adsorption on Ag–Au nanoclusters with the different Au mole fractions supported on the carbon nanotubes with the different diameters. Our thermodynamic results shown that the saturation value of coverage and the enthalpy of adsorption increases as the mole fraction of Au is increased. Our structural results showed that the presence of the H2 gas exerts a significant effect on the nanocluster surface atoms and tends to stabilize the surface atoms on the nanocluster. Also, the structural changes are irreversible in such a way that by gradually decreasing the pressure to zero, the nanocluster geometry is not reversed to its initial structure in vacuum conditions. We have also shown that the nanoclusters have smaller values of the self‐diffusion coefficients in presence of H2 molecules than those values in the initial state (vacuum), which is due to the increasing of the interface structure between the nanocluster and the nanotube.
Thermal Stability and Molecular Ordering of Organic Semiconductor Monolayers: Effect of an Anchor Group
Authors: Jones Andrew O. F. , Knauer Philipp , Resel Roland , Ringk Andreas , Strohriegl Peter , Werzer Oliver , Sferrazza Michele
Published: April 2015

The thermal stability and molecular order in monolayers of two organic semiconductors, PBI‐PA and PBI‐alkyl, based on perylene derivatives with an identical molecular structure except for an anchor group for attachment to the substrate in PBI‐PA, are reported. In situ X‐ray reflectivity measurements are used to follow the stability of these monolayers in terms of order and thickness as temperature is increased. Films have thicknesses corresponding approximately to the length of one molecule; molecules stand upright on the substrate with a defined structure. PBI‐PA monolayers have a high degree of order at room temperature and a stable film exists up to 250 °C, but decomposes rapidly above 300 °C. In contrast, stable physisorbed PBI‐alkyl monolayers only exist up to 100 °C. Above the bulk melting point at 200 °C no more order exists. The results encourage using anchor groups in monolayers for various applications as it allows enhanced stability at the interface with the substrate.
Nuclear‐Spin‐Induced Circular Dichroism in the Infrared Region for Liquids
Authors: Chen Fang , Yao Guo‐hua , Zhang Zhen‐lin , Liu Fan‐chen , Chen Dong‐ming
Published: April 2015

Recently, the nuclear‐spin‐induced optical rotation (NSOR) and circular dichroism (NSCD) for liquids were discovered and extensively studied and developed. However, so far, nuclear‐spin‐induced magnetic circular dichroism in the IR region (IR‐NSCD) has not been explored, even though all polyatomic molecules exhibit extensive IR spectra. Herein, IR‐NSCD is proposed and discussed theoretically. The results indicate that in favorable conditions the IR‐NSCD angle may be much larger than the NSOR angle in the UV/Vis region due to a vibrational resonance effect and can be measurable by using the NSOR experiment scheme. IR‐NSCD can automatically combine and give NMR spectra and IRCD spectra of the nuclear spin prepolarized samples in liquids, which, in principle, could be developed to become a unique, novel analytical tool.
Folding‐Induced Modulation of Excited‐State Dynamics in an Oligophenylene–Ethynylene‐Tethered Spiral Perylene Bisimide Aggregate
Authors: Son Minjung , Fimmel Benjamin , Dehm Volker , Würthner Frank , Kim Dongho
Published: April 2015

The excited‐state photophysical behavior of a spiral perylene bisimide (PBI) folda‐octamer (F8) tethered to an oligophenylene–ethynylene scaffold is comprehensively investigated. Solvent‐dependent UV/Vis and fluorescence studies reveal that the degree of folding in this foldamer is extremely sensitive to the solvent, thus giving rise to an extended conformation in CHCl3 and a folded helical aggregate in methylcyclohexane (MCH). The exciton‐deactivation dynamics are largely governed by the supramolecular structure of F8. Femtosecond transient absorption (TA) in the near‐infrared region indicates a photoinduced electron‐transfer process from the backbone to the PBI core in the extended conformation, whereas excitation power‐ and polarization‐dependent TA measurements combined with computational modeling showed that excitation energy transfer between the unit PBI chromophores is the major deactivation pathway in the folded counterpart.

Authors: Sha Zhou , Sun Jiulong , Chan Hardy Sze On , Jaenicke Stephan , Wu Jishan
Published: April 2015

Visible‐light photocatalysts that degrade organic pollutants in an efficient and recyclable way are highly desirable for water treatment. In this study, UiO‐66, a zirconium‐based metal–organic framework, was conjugated with AgI to obtain a composite for use as photocatalyst. The AgI/UiO‐66 composites with different composition ratios were synthesized by a simple solution method and exhibited remarkable activity for the degradation of rhodamine B (RhB) under visible‐light irradiation. The scanning electron microscopy and X‐ray diffraction results confirmed the outstanding structural stability of the AgI/UiO‐66 photocatalysts. The photocatalytic stability of the AgI/UiO‐66 composite was further examined by reusing AgI/UiO‐66 for long‐term dye degradation. The good stability of the AgI/UiO‐66 composite can be attributed to the outstanding stability of the UiO‐66 framework material, as well as the good interaction between AgI and the UiO‐66 framework. The mechanism of the photocatalytic RhB degradation by AgI/UiO‐66 was investigated by introducing different scavengers to compete for the possible reactive species involved in the degradation process.

Published: April 2015

A series of self‐supported chiral polymeric MnIII N,N′‐ethylenebis(salicylimine) (salen) complexes were synthesized through metalation of the corresponding salen ligands obtained by condensation of several bis/tris‐aldehydes with (1R,2R)‐1,2‐diaminocyclohexane. Upon employment in the asymmetric epoxidation reaction of nonfunctionalized olefins, all complexes showed enhanced activity and enantioselectivity relative to the classical Jacobsen’s monomeric salen complex. However, 1,3,5‐triazole‐based polymeric MnIII salen complex 7 was noticeably preferred over others owing to its ability to render higher enantioselectivity at the expense of lower catalyst loading. Furthermore, complex 7 was recycled and reused in eight recycling experiments with marginal loss in catalytic activity.
On the habitus modification of silver microcrystals by electrolityc origin

Published: April 2015

We present experimental facts on the role of electrolyte pH in shape control of electrodeposited small silver microcrystals. Increasing electrolyte pH value, i.e. the transition from acidic to alkali solutions, causes the change of microcrystal habitus from strongly distorted (pH ∼ 4) through faceted (pH ∼ 7) to smooth hemispheric (pH ∼ 10) ones. At neutral pH ∼ 7 the observed silver microcrystals demonstrated shapes with pentagonal symmetry including icosahedral microcrystals with incoming pentagonal facets at the icosahedron vertices that is unique for single‐component small metallic particles. Such faceting has previously been reported only for bicompounent B6O icosahedral small particles [H. Hubert et al., Nature 391, 376 (1998)].
Phase‐controlled crystallization of amorphous calcium carbonate in ethanol‐water binary solvents
Authors: Hu Yadong , Zhou Yinghua , Xu Xurong , Tang Ruikang
Published: April 2015

The evolution of amorphous calcium carbonate (ACC) into crystals in ethanol/water binary solvents under ambient temperature was investigated, and it was found to depend on the volume ratio of ethanol to water (R). Calcite remained dominant when the amount of water was high (R = 1/3). A slight change in the amount of ethanol (R = 3/1) could lead to a dramatic change in the polymorph from calcite to aragonite. However, when poly (allylamine hydrochloride) (PAH) was added at R = 3/1, almost pure vaterite could be obtained, which has a specific morphological variation (from hollow microspheres to cloud‐like). This study provides an alternative polymorphic route for the CaCO3 mineral by using the evolution of ACC in different solvent environments, which provides some useful clues for understanding the importance of kinetic control of the morphologies and polymorphs of a wide range of inorganic materials. In addition, this simple mild phase‐controlled synthetic method could be scaled up as a green chemistry route for the industrial production of different polymorphs of CaCO3.
Porous Co3O4/CuO Composite Assembled from Nanosheets as High‐Performance Anodes for Lithium‐Ion Batteries
Authors: Hao Qin , Zhao Dianyun , Duan Huimei , Xu Caixia
Published: April 2015

Upon dealloying a carefully designed CoCuAl ternary alloy in NaOH solution at room temperature, a Co3O4/CuO nanocomposite with an interconnected porous microstructure assembled by a secondary structure of nanosheets was successfully fabricated. By using the dealloying strategy, the target metals directly grew to form uniform bimetallic oxide nanocomposites. Owing to the unique hierarchical structure and the synergistic effect of both active electrode materials, the Co3O4/CuO nanocomposite exhibits much enhanced electrochemical performance with higher capacities and better cycling stability compared to anodes of pure Co3O4. Moreover, it performs excellently in terms of cycle reversibility, Coulombic efficiency, and rate capability, at both low or high current rates. With the advantages of unique performance and ease of preparation, the as‐made Co3O4/CuO nanocomposite demonstrates promising application potential as an advanced anode material for lithium‐ion batteries.

Published: April 2015

Noble‐metal‐free copper–zinc nanoalloy (<150 nm) is found to be uniquely suited for the highly selective catalytic conversion of 5‐hydroxymethylfurfural (HMF) to potential biofuels or chemical building blocks. Clean mixtures of 2,5‐dimethylfuran (DMF) and 2,5‐dimethyltetrahydrofuran (DMTHF) with combined product yields up to 97 % were obtained at 200–220 °C using 20–30 bar H2. It is also possible to convert 10 wt % HMF solutions in CPME, with an excellent DMF yield of 90 %. Milder temperatures favor selective (95 %) formation of 2,5‐furandimethanol (FDM). The one‐pot conversion of fructose to valuable furan‐ethers was also explored. Recycling experiments for DMF production show remarkable catalyst stability. Transmission electron microscopy (TEM) characterization provides more insight into morphological changes of this intriguing class of materials during catalysis.
A bidirectional DC/DC converter charge/discharge controller for solar energy illumination system integrating synchronous rectification SEPIC converter and active clamp flyback converter
Authors: Wu Yu‐En , Huang Kuo‐Chan , Li Ming‐Xuan
Published: April 2015

This paper presents a novel bidirectional DC‐to‐DC converter charge/discharge controller for solar energy illumination system. The bidirectional converter architecture integrates the synchronous rectification Single Ended Primary Inductor Converter (SEPIC) converter and an active clamp flyback converter. In addition to fully use the properties of the shared components and compensate for the shortcomings of conventional two‐stage illumination systems, the proposed system has the advantages of soft‐switching, simple structure, and high efficiency. During daytime, a SEPIC converter with synchronous rectification function was used to charge the lead acid battery through three‐stage charging and maximum power point tracking. At night, the battery discharges, driving and dimming high‐brightness LEDs using the active clamp flyback converter. Finally, a solar energy illumination system with both a 160 W charge/discharge controller and an 80 W LED driver was implemented to verify the feasibility and practicality of the proposed system.

Gas Chromatography Analysis of Discharge Products in N2‐CH4 Gas Mixture at Atmospheric Pressure: Study of Mimic Titan's Atmosphere
Authors: Torokova L. , Watson J. , Krcma F. , Mazankova V. , Mason N. J. , Horvath G. , Matejcik S.
Published: April 2015

In this paper, we report presence of various organic products formed in a flowing atmospheric glow discharge fed by gas mixture containing 1‐5 % of methane in nitrogen, which mimics the Titan's atmosphere. Gaseous products from the discharge exhaust were analysed by Gas Chromatography with Mass Spectrometry (GC‐MS). The experimental results revealed C2H2, HCN, and CH3CN as the major products. Various hydrocarbons and nitriles were the other determined gaseous products. Whilst many of these compounds have been predicted and/or observed in the Titan atmosphere, the present plasma experiments provide evidence of both the chemical complexity of Titan atmospheric processes and the mechanisms by which larger species grow prior to form the dust that should cover much of the Titan's surface.

Second Harmonic Generation of Self Focused Cosh‐Gaussian Laser Beam in Collisionless Plasma
Authors: Singh A. , Gupta N.
Published: April 2015

This paper presents an investigation of self‐focusing of a Cosh‐Gaussian (ChG) laser beam and its effect on second harmonic generation in collisionless plasma. In the presence of ChG laser beam the carriers get redistributed from high field region to low field region on account of ponderomotive force as a result of which a transverse density gradient is produced in the plasma which in turn generates an electron‐plasma wave at pump frequency. Generated plasma wave interacts with the incident laser beam and hence generates its second harmonics. Moment theory has been used to derive differential equation governing the evolution of spot size of ChG laser beam propagating through collisionless plasma. The differential equation so obtained has been solved numerically. The effect of decentered parameter, intensity of ChG laser beam and density of plasma on self‐focusing of the laser beam and second harmonic yield has been investigated.

Published: April 2015

The equation of state of binary ionic mixtures of similar ions, such as nitrogen, oxygen and carbon, has been extensively studied. The study of dense asymmetric mixtures, where Z2 >> Z1, has primarily focused on mixtures of hydrogen and iron at solar conditions. Using molecular dynamics simulations, we examine the behavior of highly asymmetric binary ionic mixtures, where the coupling of the high‐Z species may be orders of magnitude higher than the coupling of the low‐Z species. For the conditions we have studied, we find that strong correlations and signatures of solidification occur in the high‐Z species, while the low‐Z species exists as a freely flowing fluid within the high‐Z solid matrix. Solidification of the low‐Z species is correlated with the coupling between the two components. Using the Widom expansion method, we compute the plasma screening enhancement of the nuclear reaction rates for Z = 1 in a high‐Z matrix. We also provide some estimates of the coefficient of binary diffusion in the mixture. (© 2015 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Redox proteomic analysis of mytilus edulis gills: effects of the pharmaceutical diclofenac on a non‐target organism
Authors: Jaafar Siti Nur Tahirah , Coelho Ana Varela , Sheehan David
Published: April 2015

Veterinary and human pharmaceuticals are an emerging category of chemical pollutants with potential to cause serious toxicity to non‐target organisms. Filter‐feeding aquatic organisms such as mussels are especially threatened. In this study, the blue mussel, Mytilus edulis, was exposed to two doses (0.2 mg/L and 1 mg/L) of the anti‐inflammatory diclofenac. Effects on the gill, the principal feeding organ of mussels, were investigated. It was noted that, while no effect was evident on gill glutathione transferase or catalase activities, there was a tissue‐specific increase in glutathione reductase activity and reduction in total protein thiol groups. Two dimensional electrophoresis was performed and some affected proteins identified by in‐gel tryptic digestion and peptide mass fingerprinting. Of these, four unique proteins (caspase 3/7‐4, heat‐shock cognate protein 70, a predicted enolase‐like protein, arginine kinase) were found to be oxidized whilst eight unique proteins (β‐tubulin, actin, isocitrate dehydrogenase, arginine kinase, heavy metal‐binding HIP, cytosolic malate dehydrogenase, proteasome subunit alpha type 2, Mg: bb02e05 (glyceraldehyde‐3‐phosphate dehydrogenase) and superoxide dismutase) were found to have altered abundance. In addition, bioinformatic analysis suggested putative identities for six hypothetical proteins which either were oxidized or decreased in abundance. These were; 78 kDa glucose‐regulated protein precursor, α‐enolase, calreticulin, mitochondrial H + ‐ATPase, palmitoyl protein thioesterase 1 and initiation factor 5a. It is concluded that diclofenac causes significant oxidative stress to gills and that this affects key structural, metabolic and stress‐response proteins. Copyright © 2015 John Wiley & Sons, Ltd.

Authors: Boachie Ahmed , Kusi Appiah Edigna , Jubin Michelle , Jasper Karin
Published: April 2015

This case report describes five independent cases of children and adolescents assessed for eating disorders who disclosed using the Heimlich maneuver as a purging technique. The maneuver is meant to be used only in life or death situations, likely once or less in any person's lifetime. A child or adolescent with an eating disorder may be using it to self‐induce vomiting on a daily basis, increasing the risk of complications, including potential damage to major organs of the body. Asking patients who purge to elaborate on the methods with which they purge can provide clinicians with fuller information, improving their ability to select appropriate medical tests and interventions. Thorough investigations of physical complaints during the patient assessment may be warranted, including examining patients for possible rib fractures, hemorrhages, perforations of the hollow viscous, and other forms of blunt abdominal traumas. © 2015 Wiley Periodicals, Inc.

Authors: Amei Kenji , Yamamoto Tomohiro , Ohji Takahisa , Sakui Masaaki
Published: April 2015

We were able to reduce heating irregularities in equipment for heating beverage cans by using the high‐frequency induction heating method and determining the resulting improvement in the heating efficiency. The heating irregularity between the top and bottom of the can was reduced to less than 3°C by improving the arrangement of the heating coils for the beverage can by thinning the winding and changing the circuit configuration. The efficiency of power conversion was improved from 93.0% to 97.4%. In this paper, the configuration of the equipment and the experimental results are reported.

Published: April 2015

A series of yttrium(III)‐based compounds with three diazinedicarboxylate ligands, namely, {[Y2(μ‐pmdc)2(μ‐ox)(H2O)6]·4H2O}n (1, pmdc = pyrimidine‐4,6‐dicarboxylato, ox = oxalato), {[Y2(μ‐pmdc)3(H2O)6]·2DMF·8H2O}n (2, DMF = N,N‐dimethylformamide), {[Y2(μ3‐pmdc)2(μ‐ox)(H2O)4]·xH2O}n (3, x ≈ 4.66), {[Y(μ4‐pmdc)(NO3)(H2O)]·H2O}n (4), [Y2(μ‐pddc)3(H2O)6]·7H2O (5, pddc = pyridazine‐3,6‐dicarboxylato) and {[Y6(μ4‐pzdc)6(NO3)(H2O)16](NO3)5·2H2O}n (6, pzdc = pyrazine‐2,5‐dicarboxylato), have been prepared by different synthetic approaches. The crystal structures range from 0D to 3D architectures, and all of the compound show solvent‐occupied volumes. The thermal behaviour of these compounds has been analysed, and the open structure of 3 shows a reversible uptake/release of water. Moreover, the yttrium matrix of 3 has been doped with Eu3+ and Tb3+ ions to investigate the photoluminescence response of the hybrid materials. In addition to a tuneable emission colour through the concentration of luminescent ions and the excitation wavelength, these hybrid materials could serve as potential photofluorescent sensors for water detection through the reversible dehydration/rehydration process.
