description: Διερευνήθηκε ο μηχανισμός διάσπασης ανομοιογενών διακένων αγωγού-πλαισίου και αγωγού-ράβδου μήκους 50 cm υπό σύνθετες υψηλές τάσεις, ήτοι εφαρμόζοντας κρουστική υψηλή τάση στον αγωγό και συνεχή υψηλή τάση στο πλαίσιο ή τη ράβδο. Τα αποτελέσματα συγκρίθηκαν με τα αντίστοιχα διάκενα γειωμένου πλαισίου ή ρά-βδου. Μελετήθηκαν οι επιδράσεις της μορφής της επιβαλλόμενης κρουστικής τάσης στον αγωγό, της διαμέτρου του αγωγού, της τιμής της προϋπάρχουσας αρνητικής συνεχούς τάσης που εφαρμόζεται στο πλαίσιο ή στη ράβδο και της απόλυτης υγρασίας στην κατανομή της τάσης διάσπασης. Ο μηχανισμός διάσπασης αποσαφηνίζεται σε σχέση με τις παραμέτρους επίδρασης με έμφαση στην επίδραση της απόλυτης υγρασίας. Στο διάκενο αγωγού-ράβδου η αρνητική πόλωση της ράβδου μπορεί να οδηγήσει σε σημαντική αύξηση της διηλεκτρικής αντοχής του, ακόμα και σε διπλασιασμό της τάσης διάσπασης, ανάλογα με τη θέση της ράβδου σε σχέση με το σημείο τροφοδότησης του αγωγού. Το φαινόμενο αυτό εξαρτάται από την έκταση των DC εκκενώσεων κορώνα στα δύο ηλεκτρόδια και παρατηρείται μόνο πέραν ενός κατωφλίου στην τιμή της προϋπάρχουσας αρνητικής συνεχούς τάσης, το οποίο είναι συνάρτηση και της απόλυτης υγρασίας. της θέσης της ράβδου σε σχέση με τον αγωγό.
description: The breakdown mechanism was investigated for two non homogenous gaps, a conductor – plane gap and a conductor – rod one of 50 cm length under composite voltage, hence applying impulse voltage on the conductor and negative direct voltage on the plane or the rod. The results were compared with the same gaps when the plane or the rod was earthed. The purpose was to investigate the influence of the applied impulse voltage on the rod, the diameter of the rod, the applied DC voltage and the absolute humidity in the voltage breakdown distribution. The parameters influencing the breakdown mechanism are clarified with accent in the absolute humidity. For the conductor – rod gap the negative pre –stress of the rod results in a significant increase of the dielectric strength even doubling the voltage breakdown in conjunction with the rod position regarding the conductor lead of the impulse voltage. This effect depend upon the DC corona extend on both electrodes and can be observed beyond a certain value of the negative DC voltage and it depends on the absolute humidity, and the position of the rod.

description: We performed spectral line observations of CO J=2-1, 13CO J=1-0, and C18O J=1-0 and polarimetric observations in the 1.3 mm continuum and CO J=2-1 toward a multiple protostar system, L1448 IRS 3, in the Perseus molecular complex at a distance of ~250 pc, using the BIMA array. In the 1.3 mm continuum, two sources (IRS 3A and 3B) were clearly detected with estimated envelope masses of 0.21 and 1.15 solar masses, and one source (IRS 3C) was marginally detected with an upper mass limit of 0.03 solar masses. In CO J=2-1, we revealed two outflows originating from IRS 3A and 3B. The masses, mean number densities, momentums, and kinetic energies of outflow lobes were estimated. Based on those estimates and outflow features, we concluded that the two outflows are interacting and that the IRS 3A outflow is nearly perpendicular to the line of sight. In addition, we estimated the velocity, inclination, and opening of the IRS 3B outflow using Bayesian statistics. When the opening angle is ~20 arcdeg, we constrain the velocity to ~45 km/s and the inclination angle to ~57 arcdeg. Linear polarization was detected in both the 1.3 mm continuum and CO J=2-1. The linear polarization in the continuum shows a magnetic field at the central source (IRS 3B) perpendicular to the outflow direction, and the linear polarization in the CO J=2-1 was detected in the outflow regions, parallel or perpendicular to the outflow direction. Moreover, we comprehensively discuss whether the binary system of IRS 3A and 3B is gravitationally bound, based on the velocity differences detected in 13CO J=1-0 and C18O J=1-0 observations and on the outflow features. The specific angular momentum of the system was estimated as ~3e20 cm^2/s, comparable to the values obtained from previous studies on binaries and molecular clouds in Taurus.

description: One of the reasons people fail to support climate policies even when they would prefer such policies to be universally adopted may be that they believe that others will not reciprocate their cooperation on policy, leaving them the “suckers” who pay the cost of having unilaterally adopted pro-environmental policies. This may be particularly pronounced in intergroup settings, where groups can collectively adopt different policies. In this case, the willingness to adopt climate policies that are costly at the group level may be conditional on beliefs about the support for such policies among out-groups even after accounting for personal attitudes towards climate change (Leiserowitz et al., 2011). We conduct a cross-cultural survey to test the relationship between attitudes towards climate change, beliefs about out-groups’ support for climate policies, and willingness to adopt climate policies.

description: The flexibility and stiffness of small DNA play a fundamental role ranging from several biophysical processes to nano-technological applications. Here, we estimate the mechanical properties of short double-stranded DNA (dsDNA) having length ranging from 12 base-pairs (bps) to 56 bps, paranemic crossover (PX) DNA, and hexagonal DNA nanotubes (DNTs) using two widely used coarse-grain models $-$ Martini and oxDNA. To calculate the persistence length ($L_p$) and the stretch modulus ($γ$) of the dsDNA, we incorporate the worm-like chain and elastic rod model, while for DNT, we implement our previously developed theoretical framework. We compare and contrast all the results with previously reported all-atom molecular dynamics (MD) simulation and experimental results. The mechanical properties of dsDNA ($L_p$ $\sim$ 50nm, $γ\sim$ 800-1500 pN), PX DNA ($γ\sim$ 1600-2000 pN) and DNTs ($L_p \sim 1-10\ μ$m, $γ\sim$ 6000-8000 pN) estimated using Martini soft elastic network and oxDNA are in very good agreement with the all-atom MD and experimental values, while the stiff elastic network Martini reproduces order of magnitude higher values of $L_p$ and $γ$. The high flexibility of small dsDNA is also depicted in our calculations. However, Martini models proved inadequate to capture the salt concentration effects on the mechanical properties with increasing salt molarity. OxDNA captures the salt concentration effect on small dsDNA mechanics. But it is found to be ineffective to reproduce the salt-dependent mechanical properties of DNTs. Also, unlike Martini, the time evolved PX DNA and DNT structures from the oxDNA models are comparable to the all-atom MD simulated structures. Our findings provide a route to study the mechanical properties of DNA nanostructures with increased time and length scales and has a remarkable implication in the context of DNA nanotechnology.

Extended Very-High-Energy Gamma-Ray Emission Surrounding PSR J0622 + 3749 Observed by LHAASO-KM2A
Creators: name: LHAASO Collaboration
Publisher: name: arXiv
Year: 2021
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: We report the discovery of an extended very-high-energy (VHE) gamma-ray source around the location of the middle-aged (207.8 kyr) pulsar PSR J0622+3749 with the Large High Altitude Air Shower Observatory (LHAASO). The source is detected with a significance of $8.2σ$ for $E>25$~TeV assuming a Gaussian template. The best-fit location is (R.A., Dec.)$=(95^{\circ}\!.47\pm0^{\circ}\!.11,\,37^{\circ}\!.92 \pm0^{\circ}\!.09)$, and the extension is $0^{\circ}\!.40\pm0^{\circ}\!.07$. The energy spectrum can be described by a power-law spectrum with an index of ${-2.92 \pm 0.17_{\rm stat} \pm 0.02_{\rm sys} }$. No clear extended multi-wavelength counterpart of the LHAASO source has been found from the radio to sub-TeV bands. The LHAASO observations are consistent with the scenario that VHE electrons escaped from the pulsar, diffused in the interstellar medium, and scattered the interstellar radiation field. If interpreted as the pulsar halo scenario, the diffusion coefficient, inferred for electrons with median energies of $\sim160$~TeV, is consistent with those obtained from the extended halos around Geminga and Monogem and much smaller than that derived from cosmic ray secondaries. The LHAASO discovery of this source thus likely enriches the class of so-called pulsar halos and confirms that high-energy particles generally diffuse very slowly in the disturbed medium around pulsars.

description: We study the distribution of threshold forces at the depinning transition for an elastic system of finite size, driven by an external force in a disordered medium at zero temperature. Using the functional renormalization group (FRG) technique, we compute the distribution of pinning forces in the quasi-static limit. This distribution is universal up to two parameters, the average critical force, and its width. We discuss possible definitions for threshold forces in finite-size samples. We show how our results compare to the distribution of the latter computed recently within a numerical simulation of the so-called critical configuration.

description: We attempt to relate two recent developments: cluster algebras associated to triangulations of surfaces by Fomin-Shapiro-Thurston, and quivers with potentials and their mutations introduced by Derksen-Weyman-Zelevinsky. To each ideal triangulation of a bordered surface with marked points we associate a quiver with potential, in such a way that whenever two ideal triangulations are related by a flip of an arc, the respective quivers with potentials are related by a mutation with respect to the flipped arc. We prove that if the surface has non-empty boundary, then the quivers with potentials associated to its triangulations are rigid and hence non-degenerate.

description: We present preliminary results of the generalized Principal Component Analysis (PCA) of light curves of 82 magnetic chemically peculiar (further mCP) stars applied to 54 thousand individual photometric observations in the uvby and Hp colours taken from the "On-line database of photometric observations of mCP stars". We show that every of the observed light curves (LCs) can be, with a sufficient accuracy, represented using five parameters of a harmonic polynomial of the second order, and that the third order and higher harmonics reflect only a noise. We found that a prevailing majority of the uvbyHp LCs can be satisfactorily well represented by a linear combination of a constant term and one or two (extraordinarily three) basic, mutually orthonormal functions, which reduces the number of parameters necessarily needed to describe the set of the LCs of a particular star. While the shape of an individual LC depends on the individual distribution of photometric spots on the surface of a rotating star, its amplitude depends on the mechanism of variability. To describe the amplitude of LCs we introduce a robust quantity effective amplitude. Applying the PCA to the set of the effective amplitudes of the LCs in all five colours we revealed at least three different sources of the light variability showing different wavelength dependence. The amplitudes of all the LCs harbor a component monotonously decreasing with increasing wavelengths. The second component reaches a remarkable extremum in the $v$ colour, and is in antiphase relative to the remaining four colours. It occurs particularly at cooler mCP-s having a high degree of the chemical peculiarity. The third component reflects a remarkable diversity of the light curves in the $u$ colour found in a few mCP stars.

description: An improved Hamiltonian constraint operator is introduced in loop quantum cosmology. Quantum dynamics of the spatially flat, isotropic model with a massless scalar field is then studied in detail using analytical and numerical methods. The scalar field continues to serve as `emergent time', the big bang is again replaced by a quantum bounce, and quantum evolution remains deterministic across the deep Planck regime. However, while with the Hamiltonian constraint used so far in loop quantum cosmology the quantum bounce can occur even at low matter densities, with the new Hamiltonian constraint it occurs only at a Planck-scale density. Thus, the new quantum dynamics retains the attractive features of current evolutions in loop quantum cosmology but, at the same time, cures their main weakness.

description: Aims.We aim to locate the origin of a stealth coronal mass ejection (CME) detected in situ by the MAG instrument on board Solar Orbiter, and make connections between the CME observed at the Sun, and the interplanetary CME (ICME) measured in situ. Methods. Remote sensing data are analysed using advanced image processing techniques to identify the source region of the stealth CME, and the global magnetic field at the time of the eruption is examined using Potential Field Source Surface (PFSS) models. The observations of the stealth CME at the Sun are compared with the magnetic field measured by the Solar Orbiter spacecraft, and plasma properties measured by the Wind spacecraft. Results. The source of the CME is found to be a quiet Sun cavity in the northern hemisphere. We find that the stealth CME has a strong magnetic field in situ, despite originating from a quiet Sun region with an extremely weak magnetic field. Conclusions. The interaction of the ICME with its surrounding environment is the likely cause of a higher magnetic field strength measured in situ. Stealth CMEs require multi-wavelength and multi-viewpoint observations in order to confidently locate the source region, however their elusive signatures still pose many problems for space weather forecasting. The findings have implications for Solar Orbiter observing sequences with instruments such as EUI that are designed to capture stealth CMEs

description: We describe a calculation of the O(alpha_s^2) QCD corrections to the fully differential cross section for W and Z boson production in hadronic collisions. The result is fully realistic in that it includes spin correlations, finite width effects, gamma-Z interference and allows for the application of arbitrary cuts on the leptonic decay products of the W and Z. We have implemented this calculation into a numerical program. We demonstrate the use of this code by presenting phenomenological results for several future LHC analyses and recent Tevatron measurements, including the W cross section in the forward rapidity region and the central over forward cross section ratio.

Chemical studies of metabolites from Pacific Ocean marine sponges and the starfish Dermasterias imbricata
Creators: name: Burgoyne, David L.
Publisher: name: University of British Columbia
Year: 2008

description: A study of biologically active extracts of several Pacific Ocean marine sponges has led to the isolation of eight new and nine previously known natural products. The structures of the compounds were determined by a combination of spectroscopic data analysis and chemical interconversions. In addition, the partial synthesis of imbricatine (3), a cytotoxic metabolite of the starfish Dermasterias imbricata, was accomplished. Crude extracts from the sponge Petrosia contignata collected in Papua New Guinea showed potent cytotoxicity against the murine leukemia L1210 cell line. These extracts yielded contignasterol (24), a new highly oxygenated steroid that inhibited histamine release from rat peritoneal mast cells with an IC50 of 0.8 gM, and petrolactone (37), a new sesquiterpene with the drimane carbon skeleton. The structure of contignasterol, which contains the "unnatural" 1413 proton configuration and a cyclichemiacetal functionality in its side chain, was elucidated via spectroscopic studies of its tetraacetate and its reduction product penta acetate. A known polybrominated diphenylether 41 accounted for the cytotoxicity of the crude extracts. The sponge Acanthella sp. yielded ten sesquiterpenes, four of which were new. Compounds 80-87, 89 and 90 contained isonitrile, isothiocyanate, formamide, carbamate and chloride functional groups. In addition, violacene (88), a halogenated monoterpene previously isolated from the red algae Plocamium violaceum, was isolated from the sponge extracts. The Northeastern Pacific sponge Neoesperiopsis digitata yielded neoesperlactone (96), an eighteen carbon fatty acid derived y-lactone. In addition, the major aromatic component was found to be identical by tic and 1H NMR comparison to commercially obtained p-hydroxybenzaldehyde. The study of the Papua New Guinea sponge Pseudaxinella massa led to the identification of a novel cyclic heptapeptide pseudaxinellin (103) which contained standard protein amino acid residues with the L configuration. The study of two species of marine sponges, Ptilocaulis trachys and Amphimedon sp. , collected at Enewetak lagoon, led to the isolation and identification of the depsipeptide majusculamide C (104)which had previously been found in the blue green alga Lyngbya majuscula collected at Enewetak. The synthetic confirmation of the tetrahydroisoquinoline substructure of the starfish metabolite imbricatine (3) was accomplished using a Pictet-Spengler reaction to couple the starting materials 3-(3,5-dihydroxyphenyl) alanine methyl ester (143) and sodium 3-(4-benzyloxyphenyl) glycidate (141). A series of deprotections and protections on the resulting racemic benzyltetrahydroisoquinoline led to a product 140 that was identical by 1H NMR and mass spectroscopic analysis to the protected Raney nickel reduction product of imbricatine (3).

description: In this letter we report on the discovery of a z=2.83 Lyman-alpha Blob (LAB) found in our wide field narrow-band survey within the Spitzer First Look Survey region. The blob is extended over at least 95kpc and has a total Lyman-alpha luminosity of 2.1 x 10^44 erg/s. It is only the sixth LAB known of this scale (> 50 kpc), and is associated with an embedded continuum source in g', R, i', K & 4.5 um bands. The LAB's optical spectrum shows clumpy structures and tantalising hints of a sharp red cut-off and shear within the Ly-alpha emission line. Studies of the LAB's surface brightness profile and of the continuum counterpart's spectral energy distribution (SED) indicate that the profuse Lyman-alpha emission is consistent with being powered by cold gas accreting onto a massive dark matter halo.

Episode Adaptive Embedding Networks for Few-shot Learning

Publisher: name: arXiv

Subjects: subject: Computer Vision and Pattern Recognition (cs.CV)

description: Few-shot learning aims to learn a classifier using a few labelled instances for each class. Metric-learning approaches for few-shot learning embed instances into a high-dimensional space and conduct classification based on distances among instance embeddings. However, such instance embeddings are usually shared across all episodes and thus lack the discriminative power to generalize classifiers according to episode-specific features. In this paper, we propose a novel approach, namely \emph{Episode Adaptive Embedding Network} (EAEN), to learn episode-specific embeddings of instances. By leveraging the probability distributions of all instances in an episode at each channel-pixel embedding dimension, EAEN can not only alleviate the overfitting issue encountered in few-shot learning tasks, but also capture discriminative features specific to an episode. To empirically verify the effectiveness and robustness of EAEN, we have conducted extensive experiments on three widely used benchmark datasets, under various combinations of different generic embedding backbones and different classifiers. The results show that EAEN significantly improves classification accuracy about $10\%$ to $20\%$ in different settings over the state-of-the-art methods.

description: Cycling of carbon dioxide between the atmosphere and interior of rocky planets can stabilize global climate and enable planetary surface temperatures above freezing over geologic time. However, variations in global carbon budget and unstable feedback cycles between planetary sub-systems may destabilize the climate of rocky exoplanets toward regimes unknown in the Solar System. Here, we perform clear-sky atmospheric radiative transfer and surface weathering simulations to probe the stability of climate equilibria for rocky, ocean-bearing exoplanets at instellations relevant for planetary systems in the outer regions of the circumstellar habitable zone. Our simulations suggest that planets orbiting G- and F-type stars (but not M-type stars) may display bistability between an Earth-like climate state with efficient carbon sequestration and an alternative stable climate equilibrium where CO$_2$ condenses at the surface and forms a blanket of either clathrate hydrate or liquid CO$_2$. At increasing instellation and with ineffective weathering, the latter state oscillates between cool, surface CO$_2$-condensing and hot, non-condensing climates. CO$_2$ bistable climates may emerge early in planetary history and remain stable for billions of years. The carbon dioxide-condensing climates follow an opposite trend in $p$CO$_2$ versus instellation compared to the weathering-stabilized planet population, suggesting the possibility of observational discrimination between these distinct climate categories.

We show that in this system the observed magnetic field morphology is in agreement with the standard theoretical models of the formation of Sun-like stars in magnetized molecular clouds at scales of a few hundred astronomical units; gravity has overcome magnetic support, and the magnetic field traces a clear hourglass shape. The magnetic field is substantially more important than turbulence in the evolution of the system, and the initial misalignment of the magnetic and spin axes may have been important in the formation of the binary system.

description: P-stars are compact stars made of up and down quarks in $β$-equilibrium with electrons in a chromomagnetic condensate. P-stars are able to account for compact stars as well as stars with radius comparable with canonical neutron stars. We compare p-stars with different available observations. Our results indicate that p-stars are able to reproduce in a natural manner several observations from isolated and binary pulsars.

Non-linear model equation for three-dimensional Bunsen flames

subject: FOS: Physical sciences

description: The non linear description of laminar premixed flames has been very successful, because of the existence of model equations describing the dynamics of these flames. The Michelson Sivashinsky equation is the most well known of these equations, and has been used in different geometries, including three-dimensional quasi-planar and spherical flames. Another interesting model, usually known as the Frankel equation,which could in principle take into account large deviations of the flame front, has been used for the moment only for two-dimensional expanding and Bunsen flames. We report here for the first time numerical solutions of this equation for three-dimensional flames.
Are magnetic hot stars intrinsic X-ray sources ?

subject: FOS: Physical sciences

description: Context: X-ray surveys carried out with the Einstein and ROSAT satellites have resulted in rather unexpected detections of X-ray emission from late B-type and early A-type stars. These stars possess neither winds like early-type stars nor convective envelopes as late-type stars, so that the origin and production mechanism of this X-emission is unclear. Aims: We investigate whether the presence of large magnetic fields is related to the observed X-ray emission. Methods: We carried out Chandra high-angular resolution observations of a sample of late B-type and A-type stars with measured magnetic fields in the range from 0.2 - 17 kG. Out of the selected 10 sample stars, 6 objects had been previously detected as X-ray sources, some of them, however, with high positional uncertainty and a low signal-to-noise ratio, while 4 of our sample stars do have large magnetic fields but no previous detections of X-ray emission. Results: Our Chandra data confirm all previous ROSAT detections with an extremely high significance, and the limits of the offsets between X-ray and optical positions are greatly improved. In particular, HD 215441, known as Babcock's star with the strongest magnetic field by far (17 kG) of our sample stars, a rather faint and somewhat marginal ROSAT source, can clearly be detected. However, none of the 4 ROSAT non-detections could be detected with the new Chandra observations. Conclusions: The pure existence of a magnetic field of kiloGauss strength on a late B-type or A-type star is therefore not necessarily a prerequisite for finding X-ray emission among these stars. Understanding the observed X-ray emission from Babcock's star is a challenge for observational and theoretical astrophysics.

Glassy behavior of light in random lasers

description: A theoretical analysis [Angelani et al., Phys. Rev. Lett. 96, 065702 (2006)] predicts glassy behaviour of light in a nonlinear random medium. This implies slow dynamics related to the presence of many metastable states. We consider very general equations (that also apply to other systems, like Bose-Condensed gases) describing light in a disordered non-linear medium and through some approximations we relate them to a mean-field spin-glass-like model. The model is solved by the replica method, and replica-symmetry breaking phase transition is predicted. The transition describes a mode-locking process in which the phases of the modes are locked to random (history and sample-dependent) values. The results are based on very general theory, and embrace a variety of physical phenomena.

description: Motivated by the recent progresses in the formulation of geometric theories for the fractional quantum Hall states, we propose a novel non-relativistic geometric model for the Laughlin states based on an extension of the Nappi-Witten geometry. We show that the U(1) gauge sector responsible for the fractional Hall conductance, the gravitational Chern-Simons action and Wen-Zee term associated to the Hall viscosity can be derived from a single Chern-Simons theory with a gauge connection that takes values in the extended Nappi-Witten algebra. We then provide a new derivation of the chiral boson associated to the gapless edge states from the Wess-Zumino-Witten model that is induced by the Chern-Simons theory on the boundary.

Reversible binding of dihydrogen to dinuclear ruthenium complexes containing chelating diphosphines
Creators: name: Chau, Daniel Elliot Kwok-Yue
Publisher: name: University of British Columbia
Year: 2008

description: The preparation of dinuclear mixed-valence ruthenium complexes of general formula Ru₂Cl₅(P-P)₂, previously reported for a range of chelating ditertiary phosphines including chiral systems, has been extended to include compounds of the diphosphine 1,4-bis(dicyclohexylphosphino)butane (P-P = DCYPB). The complexes are generally prepared by the reaction of RuCl₃(PR₃)₂(DMA)‧DMA, R = phenyl or p-tolyl, DMA = N,N-dimethylacetamide, with one equilvalent of the appropriate diphosphine. The H₂-reduction of Ru₂Cl₅(P-P)₂ complexes in DMA, or in toluene in the presence of an added base, generally gives the dinuclear Ru(II,II) complexes [RuCl(P-P)(μ-Cl)]₂, but the DCYPB species was not formed; the procedures with DCYPB (including studies in CH₂Cl₂) led to poorly characterised complexes which may be polynuclear polyhydrides and appear to contain an η²-H₂ ligand. ¹H and ³¹P{¹H}NMR spectroscopy was used extensively to study the systems. The previously reported reaction of the dinuclear ruthenium(II) complex, [RuCl(DPPB)(μ-Cl)]₂ (DPPB = 1,4-bis(diphenylphosphino)butane), with 1 atm H₂ at ambient temperature to give the molecular hydrogen complex (η²-H₂)Ru(DPPB)(μ-Cl)₃RuCl(DPPB), has been extend to the 1,3-bis(diphenylphosphino)propane (DPPP) system; a corresponding η²-H₂ species with the DCYPB ligand has been detected following reaction of Ru₂Cl₅(DCYPB)₂ with H₂. The η²-H₂ ligands in the DPPP and DCYPB systems have internuclear distances of 0.86 Å as estimated by ¹H NMR variable temperature spin-lattice relaxation data (T₁(min) = 12 ms at 300 MHz). With the DPPP system, a ¹JHD of 29.4 Hz was found for the η²-HD isotopomer, and the η²-H₂ ligand is replaceable by N₂. The reversible equilibrium conversion under H₂ of [RuCl(DPPB)₂(μ-Cl)]₂, 9, to (η²-H₂)Ru(DPPB)(μ-Cl)₃RuCl(DPPB), 9a , in CH₂Cl₂ has been studied at 0-25°C by UV-vis and ³¹P{¹H}NMR spectroscopy, and by stopped-flow kinetics; the equilibrium constant and the corresponding thermodynamic parameters, and the forward and reverse rate constants have been determined. The equilibrium is close to being thermally neutral (ΔH° ~ zero), while a ΔS° value of ~60 J/mol K indicates the involvement of solvent molecules. A rough estimate of -60 kJ/mol is made for ΔH° of the process RuII + H₂ → RuII(η²-H₂). Preliminary studies were made on the reaction of [RuCl(DPPB)₂(μ-Cl)]₂, 9, with O₂, which may give a peroxide, and the subsequent reaction of this product with H₂; the latter reaction results in the formation of water and regeneration of a mixture of 9 and 9a.
