Hydroxy‐Functionalized Near‐Infrared Squaraine Dyes for Advanced Organic Conjugates and Hybrid Materials

Small, EarlyView.
The synthesis of hydroxy‐linker functionalized near‐infrared squaraine dyes is detailed and coupling reactions with silica nanoparticles, polymer end groups and an electron acceptor are demonstrated. New avenues of chemically linked near‐infrared organic conjugates and hybrid materials in fluorescence imaging, as photothermal additives or for ...

Additive Manufacturing of Hot‐Work Tool Steel by In Situ Alloying Using Laser Powder Bed Fusion and Directed Energy Deposition—Strategies to Improve Chemical Homogeneity

steel research international, EarlyView.
To support future alloy development a powder mixture is processed by laser additive manufacturing. The powder mixture containing Mo‐ and W‐rich tracers is processed by powder bed fusion using single and double laser exposure and by directed energy deposition which provides drastically enlarged melt pools.

Influences of Cleanliness, Carbide Size, Hardness, and Residual Stresses on Long‐Life Fatigue Strength and Crack‐Initiation Mechanisms in Carbide‐Rich Cold‐Work Tool Steels Using Normalized S–N Curves and Database‐Driven Validation of Murakami's √Area Model

steel research international, EarlyView.
Rotating‐bending fatigue tests on AISI D2 and AISI A11 quantify how cleanliness, carbide structure, hardness, and fabrication‐induced compressive residual stresses govern long‐life fatigue at NG = 107 cycles. Statistical fracture‐surface analysis and extreme‐value √area statistics link crack‐initiators to LLF strength.

When Time Stands Still: The Destructive Experience of Ambiguous Loss among Mothers of Combat Soldiers

Symbolic Interaction, EarlyView.
What happens when stories refuse coherence? This article examines ambiguous loss among mothers of combat soldiers, focusing on how prolonged waiting and uncertainty infiltrate everyday life, eroding sensemaking. Drawing on ethnographic interviews, it explores how mothers experience the contraction of time and space—manifested in suspended routines ...

Nanomedicine applications in lymphoma: Advancing precision diagnostics, targeted therapeutics, and prospective developments

VIEW, EarlyView.
Lymphoma is a group of blood cancers that can appear in lymph nodes, blood, bone marrow, spleen, liver, or the central nervous system, which makes drug delivery and disease monitoring difficult. This review summarizes how nanomedicine technologies may improve targeted treatment and imaging, while carefully separating approved or guideline‐supported ...
