Unveiling Ca9N4Te3: A New Motif in Alkaline‐Earth Metal Chalcogenide Nitrides: A Combined Experimental and Computational Study

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
The unique double monocapped trigonal cupola coordination polyhedra of Te(2) atoms inside the crystal structure of Ca9N4Te3. Green, moisture‐sensitive Ca9N4Te3 was obtained from Ca/Na flux at 1173 K as a by‐product of reddish‐brown Ca6N2Te3 and crystallizes in the trigonal space group R3¯$\overline{3}$ (No. 148, Z = 3).

Arc Resistance Enhancement of Converter Transformer Tank Through Structural Improvements: Simulation and Experimental Validation

open access: yesHigh Voltage, EarlyView.
ABSTRACT Currently, limited research exists on the structural response and protection methods of the converter transformer tank for ± 800 kV ultra‐high voltage direct current transmission project to high energy arc faults. This research investigates the dynamic response and the vulnerable areas of the ultra‐high voltage converter transformer under the ...

Can prisons move people into better jobs? A look at correctional vocational training programs and sectoral employment outcomes

open access: yesCriminology, EarlyView.
Abstract Three‐quarters of US prisons offer vocational training programs, which aim to place trainees in middle‐skills jobs in specific occupational sectors post‐release. These middle‐skills jobs may more effectively reduce recidivism than the jobs that normally characterize the labor market experience of the formerly incarcerated, yet whether ...

Identification of Autologous Tissue Sources and Optimization of a Treatment Method for Intraoperative Manufacturing of Heart Valve Constructs

open access: yesArtificial Organs, EarlyView.
The use of autologous connective tissue, such as pericardium or peritoneum, combined with controlled tissue treatment, has the potential to result in a more durable heart valve prosthesis than current commercial prostheses. ABSTRACT Introduction Valvular heart disease remains a leading cause of morbidity and mortality. Current biological and mechanical

The Theory of Critical Distances for Predicting the Static Failure of Double‐Lap Bolted Joints With Conventional and Additively Manufactured 316L Stainless Steel Inner Plates

open access: yesFatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT This study assesses the accuracy of the theory of critical distances applied in the form of the point method in predicting the static strength of 316L stainless steel double‐lap shear bolted connections under static tensile loading. Single‐ and double‐bolt configurations were tested using inner plates manufactured from conventional material ...
