Burgessite forms rosettes up to 0.8 mm across consisting of prismatic crystals up to 0.1 mm long, elongate along a , with the following forms: {011} >> { h 0 l }, and no observable twinning. It is associated with primary skutterudite, cobaltite and bismuth, and supergene arsenolite, bismutoferrite and erythrite. Burgessite is transparent, purplish pink with a slight brown tint, and has a colorless to pale pink streak and a vitreous luster; it does not fluoresce under ultraviolet light. It exhibits two cleavages, {010} good and {001} fair. The Mohs hardness is ~3; burgessite is brittle with a hackly fracture, and has measured and calculated densities of 2.93(2) and 2.94 g/cm 3 , respectively. Burgessite is biaxial positive with α 1.596, β 1.604, γ 1.628, all ±0.002, with a 2 V obs of 70(2)° and 2 V calc = 61°. It is nonpleochroic, with an optic orientation X = b , Y ∧ c = 29° (in β obtuse), Z ∧ a = 20° (in β acute). Burgessite is monoclinic, space group P 2 1 /n , a 4.7058(12), b 9.299(3), c 12.738(4) A, β 98.933(8)°, V 550.6(5) A 3 , Z = 2, a:b:c = 0.5061:1:1.3698. The strongest seven lines in the X-ray powder-diffraction pattern [ d in A(I)( hkl )] are: 7.446(100)(011), 6.267(44)(002), 3.725(29)(022), 3.260(25)(121), 2.998(31)(031), 2.970(21)(014) and 2.596(23)(024). A chemical analysis with an electron microprobe gave As 2 O 5 47.91, P 2 O 5 0.03, CoO 27.31, NiO 3.52, ZnO 0.04, CaO 0.18, SO 3 0.13, H 2 O (calc.) 22.65, for a sum of 101.77 wt. %; the valence states of As and Co, and the amount of H 2 O, were determined by crystal-structure analysis. The resulting empirical formula on the basis of 13 (O, OH, H 2 O) anions is (Co 1.75 Ni 0.23 Ca 0.02 ) ∑2.00 (AsO 3 OH) ∑2.00 (H 2 O) 5 . The crystal structure of burgessite consists of chains of the form [Co 2 (H 2 O) 4 (As 5+ O 3 (OH)) 2 ] that extend in the a direction and are linked by hydrogen bonds, and is closely related to that of erythrite.
Synthesis, crystal structure, DNA-binding properties, and antioxidant activity of a V-shaped ligand bis(N-methylbenzimidazol-2-ylmethyl)benzylamine and its zinc(II) complex

A V-shaped ligand bis(N-methylbenzimidazol-2-ylmethyl)benzylamine (L) and its zinc(II) complex, [ZnL 2](pic)2 · 2CH3CN (pic = picrate), have been synthesized and characterized by physico-chemical and spectroscopic methods. Single-crystal X-ray crystallographic analysis revealed that the Zn(II) complex possesses a distorted trigonal bipyramidal geometry. Supramolecular interactions arising from various intra- or intermolecular π···π stacking interactions contributed to the form of the multidimensional configuration. Interactions of L and Zn(II) complex with DNA were monitored using spectrophotometric methods and viscosity measurements. The results suggest that L and Zn(II) complex both bind to DNA via intercalation and Zn(II) complex binds to DNA more strongly than L. Moreover, the Zn(II) complex also exhibited potential antioxidant properties in vitro.

Effect of parity on metabolic and oxidative stress profiles in Holstein dairy cows

Background and Aim: Pregnancy and lactation have an impact on health status of animals and constitute burden on body metabolites and the oxidant-antioxidant equilibrium. This study is aimed at evaluating metabolic and oxidative stress patterns and parity impacts in both primiparous and multiparous dairy cows. Materials and Methods: Twenty-seven primiparous and multiparous. Holstein cows were enrolled and categorized into four groups according to their physiologic status: Primiparous peripartum heifer (n=5), primiparous postpartum cow (n=9), multiparous peripartum cows (n=5), and multiparous postpartum cows (n=8). Blood sample was taken from each animal – peripartum groups at 3 weeks prepartum and postpartum groups at 3 weeks post-parturition – for complete blood picture, glucose, cholesterol, triglyceride, total protein, albumin, non-esterified fatty acids (NEFA), malondialdehyde (MDA), total antioxidant capacity, and haptoglobin estimation. Results: Postpartum primiparous cows showed significant decrease in glucose, total protein, and albumin while showing significant increase in MDA, NEFA, and globulin; on the other hand, multiparous postpartum cows showed significant decrease in glucose, total protein, and albumin, associated with significant increase in cholesterol and MDA when compared with prepartum PP and MP cows, respectively. Postpartum multiparous cows significantly showed reduction in NEFA when compared to primiparous postpartum cows. Hematologic profiles of postpartum primiparous and multiparous cows showed significant decrease in red blood cells and packed cell volume, significant increase in lymphocytes when compared with prepartum cows. Conclusion: Metabolic and oxidative abnormalities exist in both primiparous and multiparous cows during the transition phase, however postpartum primiparous cows show higher susceptibility to negative energy balance impacts. Oxidant/antioxidant imbalance occurred in both the primiparous and multiparous postpartum cows, highlighting the importance of oxidative stress profiles in the assessment of metabolic health status during transition.

Hyperbranched conjugated poly(tetraphenylethene): synthesis, aggregation-induced emission, fluorescent photopatterning, optical limiting and explosive detection

Tetraphenylethene-containing diyne (1), named 1,2-bis(4-ethynylphenyl)-1,2-diphenylethene, was synthesized and polymerized by TaBr5 catalyst, affording the hyperbranched polymer hb-P1 with a high molecular weight (Mw up to 157 800) in a nearly quantitative yield. The cyclotrimerization of 1-(4-ethynylphenyl)-1,2,2-triphenylethene was also carried out to give 1,3,5- and 1,2,4-tris[4-(1,2,2-triphenylvinyl)phenyl]benzene (1,3,5-2 and 1,2,4-2) that served as model compounds for structural characterization and properties investigation. The structures of hb-P1 and 2 are characterized by MS, IR, and NMR spectroscopies with satisfactory results. All the molecules and polymer are completely soluble in common organic solvents such as chloroform, toluene and THF. They show high thermal stability with degradation temperatures up to 443 and 446 °C, respectively, in nitrogen and air. Whereas their solutions are almost non-emissive or weakly fluorescent, their aggregates in poor solvents and solid powders emit intensely with fluorescence quantum yields up to 81%, demonstrating a novel phenomenon of aggregation-induced or enhanced emission. The unreacted triple bonds on the periphery of hb-P1 allow its thin film to cross-link under UV irradiation, generating well-resolved photopatterns. The hyperbranched polymer can limit harsh laser pulses. Its emission can be quenched efficiently by picric acid in solution and aggregated states with large quenching constants, suggesting that it is a promising fluorescent chemosensor for explosives detection.
Kinetic and equilibrium models for the biosorption of Cr(III) on Streptomyces rimosus

This study focused on the biosorption of trivalent chromium onto mycelial bacterium (Streptomyces rimosus) biomass from effluent of tannery. The biomass was prepared by treatment with alkali. Fourier transforms-infra red analysis of the mycelial bacterial revealed the presence of carboxyl groups as possible binding sites. Experimental parameters affecting biosorption processes such as pH contact time were studied. Langmuir, Freundlich, and Temkin models were applied to describe the biosorption isotherms. The Langmuir model fitted the equilibrium data better than the Freundlich isotherm. The biosorption capacity of S. rimosus biomass for trivalent chromium was found to be 83 mg g−1 at pH 4.8 and 3 g L−1 biomass dosage, 300 min equilibrium time and 20°C. Kinetic evaluation of experimental data showed that the biosorption processes of trivalent chromium followed pseudo-second-order kinetics well.
Metallurgical mechanism and optical properties of CuSnZnSSe powders using a 2-step sintering process

Cu2SnZn(S + Se)4 is an excellent absorber material for solar cells. This study obtained Cu2SnZn(S + Se)4 powders through solid state reaction by the ball milling and sintering processes from elemental Cu, Zn, Sn, S, and Se without using either polluting chemicals or expensive vacuum facilities. Ratios of S/S + Se in CuSnZnSSe were controlled from 0 to 1. The results showed that the 2-step sintering process (400°C for 12 hrs and then 700°C for 1 hr) was able to stabilize the composition and structure of the CuSnZnSSe powders. The crystallized intensity of the CuSnZnS matrix decreased with increasing the Se content. Raising the Se content restrained the SnS phase and reduced the resistance of the absorber layer. In addition, Raman data confirmed that Se caused a Raman shift in the CuSnZnSSe matrix and enhanced the optical properties of the CuSnZnSSe powders. For the interface of CuSnZnSSe film and Mo substrate, Mo could diffuse into CuSnZnSSe matrix after 200°C annealing. The interface thermal diffusion of CuSnZnSSe/ZnS improved the effects of stack to enhance the stability of structure.

Calciolangbeinite, K2Ca2(SO4)3, a new mineral from the Tolbachik volcano, Kamchatka, Russia

Abstract The new mineral calciolangbeinite, ideally K2Ca2(SO4)3, is the Ca-dominant analogue of langbeinite. It occurs in sublimates at the Yadovitaya fumarole on the Second scoria cone of the Northern Breakthrough of the Great Tolbachik Fissure eruption, Tolbachik volcano, Kamchatka, Russia. The mineral is associated with langbeinite, piypite, hematite, rutile, pseudobrookite, orthoclase, lyonsite, lammerite, cyanochroite and chlorothionite. Calciolangbeinite occurs as tetrahedral to pseudooctahedral crystals, which are bounded by {111} and {111̅}, and as anhedral grains up to 1 mm in size, aggregated into clusters up to 2 mm across, and forming crusts covering areas of up to 1.5 6 1.5 cm on the surface of volcanic scoria. Late-stage calciolangbeinite occurs in complex epitaxial intergrowths with langbeinite. Calciolangbeinite is transparent and colourless with white streak and vitreous lustre. Its Mohs’ hardness is 3-3½. It is brittle, has a conchoidal fracture and no obvious cleavage. The measured and calculated densities are D meas = 2.68(2) and D calc = 2.74 g cm-3, respectively. Calciolangbeinite is optically isotropic with n = 1.527(2). The chemical composition of the holotype specimen is Na2O 0.38, K2O 21.85, MgO 6.52, CaO 16.00, MnO 0.27, FeO 0.08, Al2O3 0.09, SO3 55.14, total 100.63 wt. %. The empirical formula, calculated on the basis of twelve oxygen atoms per formula unit, is K2.01(Ca1.24Mg0.70Na0.05Mn0.02Fe0.01Al0.01)S 2.03S3. 00O12. Calciolangbeinite is cubic, space group P213, a = 10.1887(4) Å, V = 1057.68(4) Å3 and Z = 4. The strongest reflections in the X-ray powder pattern [listed as (d,Å(I)(hkl)] are 5.84(8)(111); 4.54(9)(120); 4.15(27)(211); 3.218 (100) (310, 130); 2.838 (8) (230, 320), 2.736 (37) (231, 321), 2.006 (11) (431, 341) , 1.658(8)(611,532,352). The crystal structure was refined from single-crystal X-ray diffraction data to R = 0.0447. The structure is based on the langbeinite-type three-dimensional complex framework, which is made up of (Ca,Mg)O6 octahedra (Ca and Mg are disordered) and SO4 tetrahedra. Potassium atoms occupy two sites in voids in the framework; K(1) cations are located in ninefold polyhedra whereas K(2) cations are sited in significantly distorted octahedra. Calciolangbeinite and langbeinite are isostructural and form a solid-solution series.
Identity Unbiased Deception Detection by 2D-to-3D Face Reconstruction

Deception is a common phenomenon in society, both in our private and professional lives. However, humans are notoriously bad at accurate deception detection. Based on the literature, human accuracy of distinguishing between lies and truthful statements is 54% on average, in other words, it is slightly better than a random guess. While people do not much care about this issue, in high-stakes situations such as interrogations for series crimes and for evaluating the testimonies in court cases, accurate deception detection methods are highly desirable. To achieve a reliable, covert, and non-invasive deception detection, we propose a novel method that disentangles facial expression and head pose related features using 2D-to-3D face reconstruction technique from a video sequence and uses them to learn characteristics of deceptive behavior. We evaluate the proposed method on the Real-Life Trial (RLT) dataset that contains high-stakes deceits recorded in courtrooms. Our results show that the proposed method (with an accuracy of 68%) improves the state of the art. Besides, a new dataset has been collected, for the first time, for low-stake deceit detection. In addition, we compare high-stake deceit detection methods on the newly collected low-stake deceits.
Fast Exact Matrix Completion: A Uniﬁed Optimization Framework

We formulate the problem of matrix completion with and without side information as a non-convex optimization problem. We design fastImpute based on non-convex gradient descent and show it converges to a global minimum that is guaranteed to recover closely the underlying matrix. fastImpute scales up to matrices of sizes 10 5 × 10 5 . We report experiments on both synthetic and real-world datasets that show fastImpute is competitive in both the accuracy of the matrix recovered and the time needed across all cases. Furthermore, when a high number of entries are missing, fastImpute is over 75% lower in MAPE and 15 times faster than current state-of-the-art matrix completion methods in both the case with side information and without.
Autonomous Driving Via Context-aware Multi-sensor Perception and Enhanced Inverse Reinforcement Learning

Despite significant advancements, collision-free navigation in autonomous driving is still challenging. On one hand, the perception module needs to interpret multimodal unstructured data and produce structured data of the environment. On the other hand, the navigation module needs to balance the use of machine learning and motion planning in order to achieve efficient and effective control of the vehicle. We propose a novel framework combining context-aware multisensor perception and enhanced inverse reinforcement learning (EIRL) for autonomous driving. Our perception module not only achieves the highest “mean Average Precision” (mAP) scores across all test cases in the KITTI dataset, but also suppresses up to 15% false positives, compared to other recent methods. The EIRL module implements several attributes including non-uniform prior for features, model parameter reuse for continuous training, and learning from accidents. These attributes help reduce the number of collisions of the vehicle up to 41%, increase the training efficiency by 2.5x, and obtain higher test scores up to two orders of magnitude. Overall, our method can enable the vehicle to drive 10x further than other methods, while achieving collision avoidance over both static and dynamic obstacles.

Understanding short-side-chain perfluorinated sulfonic acid and its application for high temperature polymer electrolyte membrane fuel cells

The great demand for high-temperature operation of polymer electrolyte membrane fuel cells (PEMFCs) has been well answered by short-side-chain perfluorinated sulfonic acid (SSC-PFSA) membranes through a good balance between transport properties and stability. It has been evidenced that fuel cells assembled with SSC-PFSA possess higher and more stable performance at elevated temperature up to 130 °C compared to that of fuel cells based on conventional long-side-chain (LSC) PFSA (Nafion®) membranes. Moreover, the shorter side-pendent chains and the absence of the ether group and of the tertiary carbon also endow SSC-PFSAs with better durability, making them more suitable for working at harsh conditions in fuel cell systems. This critical review is dedicated to summarizing the properties of SSC-PFSA and providing insight into an understanding of their micro-morphologies, mass diffusion, enhanced proton transportation and their mutual correlation. Diversified measurement techniques applied to investigate the evolution of micro-morphologies, unique diffusion and transportation properties of SSC-PFSAs are reviewed. Despite the higher crystalline and higher water absorption of SSC-PFSAs than those of LSC-PFSAs, the notably less developed and less interconnected ionic clusters in SSC-PFSAs lead to lower mass permeability, and hence the high water uptake is not as well translated into transportation performance as expected. The factors and reasons for the enhanced electrochemical performance of SSC-PFSAs such as higher proton conductivity at elevated temperatures and low humidity conditions are also discussed and understood. Highlights of recent advances in SSC-PFSA-based membranes for fuel cell applications at wider temperature ranges are summarized as general references for researchers to further prompt the development of SSC-PFSAs. The SSC-PFSAs based membranes give a bright future for the next generation of high-temperature PEMFCs.
Supersolubilization in Chlorinated Hydrocarbon Microemulsions: Solubilization Enhancement by Lipophilic and Hydrophilic Linkers

In this paper, the effect of linker molecules on the solubilization capacity of an anionic surfactant system (sodium dihexyl sulfosuccinate) is studied. N-Alkyl alcohols are used as lipophilic linkers in middle-phase microemulsions of trichloroethylene, tetrachloroethylene, and hexane. The lipophilic linker effect increases the solubilization capacity of the anionic surfactant system. The solubilization parameter for both hydrocarbons and chlorinated hydrocarbon oil increases as a function of alcohol concentration. As the alkyl chain length of the alcohol linker molecule increases, the solubilization capacity increases. Moreover, the longer chain alcohol is more effective at linking oil molecules for hexane than for chlorinated hydrocarbon oils, indicating that the linker effect is more effective for higher equivilant alkane carbon number (EACN) oils. Sodium mono- and dimethylnaphthalenesulfonate is proposed as a hydrophilic linker to enhance the solubilization of lower EACN oils. The combination of lipop.

Effect of Crystallographic Structure of MnO2 on Its Electrochemical Capacitance Properties

MnO2 is currently under extensive investigations for its capacitance properties. MnO2 crystallizes into several crystallographic structures, namely, α, β, γ, δ, and λ structures. Because these structures differ in the way MnO6 octahedra are interlinked, they possess tunnels or interlayers with gaps of different magnitudes. Because capacitance properties are due to intercalation/deintercalation of protons or cations in MnO2, only some crystallographic structures, which possess sufficient gaps to accommodate these ions, are expected to be useful for capacitance studies. In order to examine the dependence of capacitance on crystal structure, the present study involves preparation of these various crystal phases of MnO2 in nanodimensions and to evaluate their capacitance properties. Results of α-MnO2 prepared by a microemulsion route (α-MnO2(m)) are also used for comparison. Spherical particles of about 50 nm, nanorods of 30−50 nm in diameter, or interlocked fibers of 10−20 nm in diameters are formed, which d.
