X-ray K-absorption studies of molybdenum sulphide, selenides and tellurides

open access: yes, 1974
X-ray K-absorption studies of molybdenum sulphide, selenides and tellurides have been carried out using 400-mm bent crystal (mica) spectrograph. K-absorption edge of molybdenum in its selenides, tellurides and sulphide lies on the higher energy side with

Sulfosalts and Sulfates in the Epithermal Au-Ag-Te Emmy Deposit (Khabarovsk Territory, Far East of Russia): Implications for the Mineralization Process

open access: yesGeosciences
This study considers the features of the chemical composition, internal structure, and oscillatory zoning of sulfosalts and sulfates in the epithermal high–intermediate-sulfidation-type Au-Ag-Te Emmy deposit (Khabarovsk Territory, Russia).

Nanoscale Thermal Transport in Bi2(Te, Se)3 Thermoelectric Material Using Pulsed STEM

open access: yesAdvanced Physics Research, EarlyView.
The pulsed‐STEM technique enables simultaneous acquisition of crystallographic, compositional, and thermal transport information within a single experiment. In anisotropic Bi2(Te, Se)3, phase‐delay imaging visualizes directional heat flow and interfacial resistance at the nanoscale, offering a new approach to understanding and designing thermoelectric ...

Exploring the Nature of Ag–Ag Interactions in Different Tellurides by Means of the Crystal Orbital Bond Index (COBI)

open access: yesInorganics
Over the decades, intensive explorations have been conducted to understand the nature of d10−d10 interactions. The recent establishment of a bonding indicator named the crystal orbital bond index stimulated our impetus to probe the capabilities of that ...

Measuring Corporate Alignment With the Circular Economy: a Text‐Based Circularity Index From Mandatory Non‐Financial Disclosures

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The transition to a circular economy (CE) has become a strategic priority for firms, yet empirical assessments of corporate circularity remain fragmented and heavily dependent on structured indicators or self‐reported metrics. This paper proposes a novel, text‐based circularity index derived from mandatory non‐financial statements of large ...

Layered Manganese Bismuth Tellurides with GeBi4Te7– and GeBi6Te10–type Structures: Towards Multifunctional Materials

open access: yes, 2019
The crystal structures of new layered manganese bismuth tellurides with the compositions Mn0.85(3)Bi4.10(2)Te7 and Mn0.73(4)Bi6.18(2)Te10 were determined by single-crystal X-ray diffraction, including the use of microfocused synchrotron radiation.

PSEUDOMORPHIC HEMATITE AFTER ORE CLASTS OF GOSSANITES OF THE MOLODEZHNOE CU-ZN MASSIVE SULFIDE DEPOSIT (SOUTH URALS) [PDF]

open access: yesМинералогия, 2019
The structural and mineralogical features of pseudomorphic hematite after ore clasts are considered for gossanites (products of complete submarine oxidation of massive sulfide ores), which form the sedimentary halos at the flanks of the Molodezhnoe Cu-Zn

Structural Engineering of Vacancy Defected Bismuth Tellurides for Thermo-electric Applications

open access: yesEPJ Web of Conferences, 2012
Molecular Dynamics and ab-initio simulations are used to find the most stable stoichiometries of Bismuth Tellurides with vacancy defects. The interest is to decrease the thermal conductivity of these compounds a key point to achieve high figure of merits.

Sustainable Germanium Recovery From Germanium Dioxide via Halogen‐Free Chemical Vapor Transport

open access: yesChemistry – A European Journal, EarlyView.
Recovery of the critical element Ge from GeO2 and SiO2/GeO2 mixtures was investigated based on an endothermic chemical vapor transport via GeO, formed with natural gas or a hydrogen(10%)‑argon(90%) mixture and water vapor. (This picture was partly created with AI, engine: Adobe Firefly).

A universal approach for the synthesis of two-dimensional binary compounds

open access: yesNature Communications, 2019
The scalable synthesis of 2D materials critically relies on finding appropriate vapour-phase metal precursors and careful fine-tuning of growth parameters.
