NEW TIN (IV), MX2 AND M’Cl3 (M= Zn, Hg; M’= Pr, Er) ADDUCTS AND COMPLEXES OF BIS(AMINOMETHYLBENZENE): SYNTHESIS AND INFRARED STUDY

Scientific Study & Research: Chemistry & Chemical Engineering, Biotechnology, Food Industry, 2015
The new adducts and complexes obtained have discrete or dimeric structures; in these structures the diamine behaves as a monodentate and hydrogen bonds involved or bidentate ligand.

Multimodal Mechanical Testing of Additively Manufactured Ti6Al4V Lattice Structures: Compression, Bending, and Fatigue

Advanced Engineering Materials, EarlyView.
In this experimental study, the mechanical properties of additively manufactured Ti‐6Al‐4V lattice structures of different geometries are characterized using compression, four point bending and fatigue testing. While TPMS designs show superior fatigue resistance, SplitP and Honeycomb lattice structures combine high stiffness and strength. The resulting

Interaction between Molten Al‐Killed Mn–B Steel and Carbon‐Bonded MgO Refractories Based on Recyclates

Advanced Engineering Materials, EarlyView.
High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.

Unique Performance Considerations for Printable Organic Semiconductor and Perovskite Radiation Detectors: Toward Consensus on Best Practice Evaluation

Advanced Functional Materials, EarlyView.
A lack of standard approaches for testing and reporting the performance of metal halide perovskites and organic semiconductor radiation detectors has resulted in inconsistent interpretation of performance parameters, impeding progress in the field. This Perspective recommends key metrics and experimental details, which are suggested for reporting in ...

Cy2NH2NO3SnBu2Cl2•H2O AND Cy2NH2NO3SnPh2Cl2•2H2O: SYNTHESIS AND INFRARED STUDY

Scientific Study & Research: Chemistry & Chemical Engineering, Biotechnology, Food Industry, 2014
On allowing Cy2NH2NO3 to react with SnBu2Cl2 and SnPh2Cl2, the two studied adducts were obtained. While considering the complex-anions [SnBu2Cl2NO3.H2O]- and [NO3.SnPh2Cl2 H2O]-, discrete structures were suggested with monocoordinating nitrate and ...
