Abstract Thorea (Rhodophyta) is a genus of freshwater red algae whose species-level taxonomy has long been disputed because of poor sample representation and seemingly random distribution. Molecular evidence has recently led to the establishment of the new order Thoreales, but the phylogeny of the recognized species a…
A small marine benthic diatom pertaining to the order Achnanthales (Bacillariophyta) was observed from the Scattered Islands (“Eparses”, Mozambique Channel, Indian Ocean) and from Napuka Atoll (North of the Tuamotu Archipelago, South Pacific). The latter taxon has unique characteristics (e.g., raphe valve striae compo…
In this work we investigate the regeneration (permanent deactivation of light induced degradation, LID) of industrial high efficiency PERC cells. This procedure transforms the boron oxygen related defects responsible for LID into a less active state. Recently it was found that the hydrogen content in the passivation l…
In order to improve the understanding flow behaviors of hot compressive deformation as‐homogenized of Mg–3.06Zn–0.58Zr–1.07Y alloy, carried out a series of isothermal compressive tests with 60% height reduction of specimens were performed at constant temperature of 523 K, 573 K, 623 K, 673 K, and 723 K, and strain rat…
Summary High temperature thermal gradient interaction chromatography (HT‐TGIC) was recently developed to characterize chemical composition distribution (CCD) of ethylene/1‐olefin copolymers based on the interaction between polymer chains and graphitic surface. In this work, a mathematical model of HT‐TGIC was develope…
The magnetic field distribution and eddy current density of the permanent magnet eddy current coupling has a great influence on the performance of the coupling. If the air gap between the inner and outer rotor is far less than the axial size, and negligible side effect, then the coupling of magnetic field can be simpl…
For nearly five years, the photoelectric conversion efficiency of the perovskite-based solar cells are extraordinarily developed at a high speed, showing a good application prospect. It is necessary to further optimize the devices and make them industrially feasible. The different temperature requirements of perovskit…
Abstract Steigende Energiepreise sowie zunehmende Folgen des Klimawandels aufgrund der Emission von Treibhausgasen haben die Notwendigkeit zum Energiesparen in den letzten Jahren verstärkt in das öffentliche Bewusstsein gerückt. Für den Einsatz als reibungsmindernde Beschichtung eignen sich insbesondere kohlenstoffbas…
Traditional methods for detecting lactoperoxidase (LP) are complex and time-consuming, so a test strip was made based on the enzymatic reaction principle to enable quick and convenient detection of LP in raw milk. In this study 0.1 mol/L citric acid (CA)/0.2 mol/L disodium hydrogen phosphate (NaP) buffer solution (pH…
Research results obtained to date by applying Mössbauer spectroscopy to iron-containing nanosized structures and the revealed patterns of how the nanoscale state impacts hyperfine interaction parameters in simple, multicomponent, and hybrid systems lay the groundwork for developing algorithms for the targeted synthesi…
ResumoNeste estudo foram desenvolvidos compósitos utilizando PEAD, pó de madeira (Pinus taeda), alumina calcinada e dois diferentes tipos de agentes compatibilizantes para avaliação das propriedades morfológicas e mecânicas dos mesmos. Para aumentar a interação entre a matriz polimérica e o pó de madeira foram utiliza…
Kinetics of Si atoms emission during the oxidation of Si(001) surfaces have been investigated using reflection high energy electron diffraction combined with Auger electron spectroscopy. The area ratio of the 1 × 2 and the 2 × 1 domains on a clean Si(001) surface changed with the oxidation of the surface by Langmuir-t…
Summary N‐phenyl‐p‐phenylenediamine modified epoxidized palm oil (m‐EPO) was synthesized and applied as an alternative processing oil in laboratory tests of rubber compounding. The effects of added functionalities in the chemical structure of m‐EPO on the properties of ENR/PP TPVs were investigated. Palm oil (PO), epo…
Creep behavior of microscale Cu/Sn-3.0Ag-0.5Cu/Cu joints with different thicknesses under electric current stressing was studied in comparison with those without current stressing. The effect of current stressing on creep mechanism was characterized by calculation of the stress exponent (n) of the steady-state creep r…
High strength bulk aluminum has been prepared by mechanical milling and press-forming processes. The bulk aluminum exhibits a high tensile strength of 537 MPa and a yield strength of 495 MPa. Characterization of microstructures reveals that the grain size of the bulk aluminum is between 0.5~5 μm. The high strength of…

Salah satu masalah yang dihadapi pada saat melakukan penyemenan adalah pada kondisi sumur yang dalam dan temperatur tinggi semen cepat mengeras pada saat pemompaan dari permukaan menuju annulus. Semakin bertambahnya temperatur, bubur semen akan lebih cepat kering dan mengeras. Oleh karena itu, untuk mengatasi hal ters…
This paper investigates the dependency of the critical content for electrical conductivity of carbon powder-filled polymer matrix composites with different matrixes as a function of the carbon powder content (volume fraction) to find the break point of the relationships between the carbon powder content and the electr…
