Molecular‐Scale Geometric Control of Organosiloxane Cage Frameworks Via Rigid Organic Bridges

open access: yesSmall Methods, EarlyView.
Rigid phenylene bridges with predefined Si–Ph–Si angles enable molecular‐level control of cage‐type organosiloxane frameworks. Hydrolysis and condensation of meta‐ and para‐bis(triethoxysilyl)benzene in the presence of tetramethylammonium hydroxide yield a mixture of cage trimers and tetramers, and hexamers, respectively, providing a new insight into ...

In Situ Alloying of H13 Tool Steel With TiC via PBF‐LB/M

open access: yessteel research international, EarlyView.
H13 tool steel is in situ alloyed with titanium carbides (TiC) in amounts up to 30 wt.%. This approach offers the advantage that the carbides melt only partially during processing, preventing excessive carbon enrichment of the steel matrix. The resulting microstructure consists of coarse, undissolved and fine, reprecipitated carbides, leading to grain ...

Near‐Atomic Investigation on the Elemental Redistribution During Coprecipitation of Nano‐Sized Kappa‐Type and B2 Precipitates in an Al‐Alloyed Lightweight Steel

open access: yessteel research international, EarlyView.
Elemental redistribution during coprecipitation of kappa (κ)‐type and B2 precipitates in an Al‐alloyed lightweight steel is revealed by atom probe tomography (APT) and density functional theory (DFT). Fe and Ni redistribution promotes the evolution of B2 phase from NiAl‐type toward FeAl‐type and improves the stability of κ and B2 phases during ...

Kikuchi Disease: Recognizing a Common Presentation of an Uncommon Condition [PDF]

open access: yes, 2016
INTRODUCTION Kikuchi disease, also known as histiocytic necrotizing lymphadenitis or Kikuchi-Fujimoto disease, is a rare condition that typically presents with fever and cervical lymphadenopathy in previously healthy young women.

Investigation of Serrated Flow in Intercritically Annealed Medium Manganese Steel by In Situ Synchrotron X‐Ray Diffraction

open access: yessteel research international, EarlyView.
Serrations and stepwise austenite phase transformation were observed in cold‐rolled and annealed medium manganese steels. By in situ XRD experiments, these two phenomena were studied simultaneously. The results show that DSA leads to the creation of PLC bands and load drops in the specimen.

Atomic‐Scale Insights Into Tramp Element Segregation and Mechanical Performance of a Low‐Carbon Steel

open access: yessteel research international, EarlyView.
Despite increased hardness, elevated tramp element concentrations in a ferritic‐pearlitic low‐carbon steel lead to enhanced toughness accompanied by a more homogeneous and finer ferritic microstructure. Atom probe tomography reveals pronounced segregation of some tramp elements at grain boundaries and ferrite–cementite interfaces, together with ...
