Reprogramming Immunogenicity of Iron Oxide Nanoparticles through Sulfated Glycan Presentation

Small, EarlyView.
This study presents a comparative analysis of heparin (HP)‐ and dextran sulfate (DS)‐coated superparamagnetic iron oxide nanoparticles (SPIONs) as a tunable immunomodulatory platform where surface chemistry dictates therapeutic function. DS‐SPIONs are preferentially internalized by myeloid cells, reprogramming them into a pro‐healing M2 phenotype ...

Polymer‐Assisted Direct and Rapid Microwave Synthesis of Mesoporous Binary and Ternary Metal Oxides for Electrocatalytic Water Oxidation

Small, EarlyView.
A novel direct and facile microwave synthesis route to prepare mesoporous binary and ternary metal oxides with P‐123® as porogen is presented. NiFe2O4 is applied in alkaline Oxygen Evolution Reaction (OER) and shows improved performance in comparison to nanoparticular and Evaporation Induced Self‐Assembly (EISA)‐derived mesoporous NiFe2O4.

Activatable smart contrast agents for photoacoustic imaging

Smart Molecules, EarlyView.
This review highlights recent advances in smart activatable photoacoustic imaging (PAI) contrast agents, which dynamically modulate their optical properties in response to external stimuli or microenvironmental cues. It discusses their molecular design, activation mechanisms, biomedical applications, and future prospects for clinically tailored use ...

Numerical Prediction of Deformation‐Induced Martensitic Transformation in Cold‐Sprayed Austenitic Stainless Steel

steel research international, EarlyView.
Cold spray deposition of stainless steel (grade: SS304) is evaluated for marine applications, with emphasis on martensitic transformation during impact. Analytical modeling, simulations, and experiments reveal that helium‐assisted spraying of fine powders promotes cooling below the martensitic start temperature, enabling up to ≈40% austenite to ...

Technical development in high‐intensity focused ultrasound for localized prostate cancer: Intraoperative compression of the prostate

UroPrecision, EarlyView.
Abstract High‐intensity focused ultrasound (HIFU) has emerged as a widely adopted, minimally invasive treatment for localized prostate cancer (PC). Although originally applied for whole‐gland treatment, recent advancements in imaging and technology have facilitated the adoption of HIFU as a focal therapy modality, targeting clinically significant ...
