Recent Advances in Variable‐Stiffness Robotic Systems Enabled by Phase‐Change Materials

open access: yesAdvanced Robotics Research, EarlyView.
Phase‐change materials (PCMs), such as shape memory alloys, hydrogels, shape memory polymers, liquid crystal elastomers, and low‐melting‐point alloys, are driving advancements in stiffness‐tunable robotic systems across a wide range of applications. This review highlights recent progress in PCM‐enabled robotics, focusing on their underlying mechanisms,

Hyperandrogenemia Induces Trophoblast Ferroptosis and Early Pregnancy Loss in Patients With PCOS via CMA‐Dependent FTH1 Degradation

open access: yesAdvanced Science, EarlyView.
In PCOS patients with hyperandrogenemia, decreased ferritin heavy chain 1 (FTH1) causes Fe2⁺ overload and ferroptosis in trophoblasts. Androgens induce FTH1 protein degradation via AR‐LAMP2A‐mediated chaperone‐mediated autophagy pathway, leading to placental development disruption and early pregnancy loss. Metformin mitigates androgen‐induced placental

Hydrodenitrogenation of Heavy Oil

open access: yesJournal of the Fuel Society of Japan, 1980
Hydrodenitrogenation (HDN) of heavy oil fractions is of interst and importance for upgrading the heavy oil because it is a means for removing basic heterocyclic nitrogen compounds which can poison acidic catalysts used in cracking and refining.The emerging synthetic fuels industry provides a second motivating factor for nitrogen removal: the need for ...

Interactions of Antibody Drug Conjugate Anti‐Tubulin and Topoisomerase I Inhibitor Payloads with Radiotherapy to Potentiate Immunotherapy

open access: yesAdvanced Science, EarlyView.
Antibody drug conjugates deliver their cytotoxic anti‐tubulin or topoisomerase I inhibitor payloads to tumors through cancer cell receptor targeting. The released drug payloads induce cellular changes that interact with radiotherapy resulting in radiosensitization that improves cancer cell kill and stimulates anti‐tumor immune responses.
