Bioinspired Materials, Designs, and Manufacturing Strategies for Advanced Impact‐Resistant Helmets

open access: yesAdvanced Engineering Materials, EarlyView.
This review explores how bioinspired materials, structures, and manufacturing strategies transform helmet design to achieve enhanced impact resistance. Drawing inspiration from nacre, porcupine quills, beetle exoskeletons, and skull architectures, it highlights advances in auxetic lattices, nanocomposites, and functionally graded foams.

Poly(1,4‐anthraquinone) as an Organic Electrode Material: Interplay of the Electronic and Structural Properties due to the Unusual Lone‐Pair‐π Conjugation

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
In this study, the unique role of the unusual lone‐pair‐π conjugation mechanism in poly(1,4‐anthraquinone) (P14AQ) is explored as an organic electrode material. Unlike traditional π‐π interactions, P14AQ's conjugation involves lone pairs of oxygen atoms interacting with the π cloud of adjacent units, enabling stable charge transport even with minimal π‐

Effect of preoperative rapamycin supplementation on perioperative clinical frailty and cognitive performance in a murine model undergoing anesthesia and surgery

open access: yesScientific Reports
The geroprotective effects of rapamycin in mitigating frailty and cognitive complications in the perioperative period remains unknown. Of 39 C57BL/6 mice tested, 19 were young (16 weeks), and 20 were old (80 weeks).

LONGEVITY OF PHYSICIANS. [PDF]

open access: yesJAMA: The Journal of the American Medical Association, 1896
All men think all men mortal, but themselves.—Young. "It is a swift current—that stream of life, on which we ride. We fall asleep, and awaking, find ourselves almost home. Our companions, too, are constantly changing; at every moment new ones come aboard, and old ones leave us, and we have scarcely time to become familiar with their faces, or to make ...

Ideal Molecular Sieving with a Dense MOF for Helium Upgrading with Highly Diffusion Selective Mixed Matrix Membranes

open access: yesAdvanced Functional Materials, EarlyView.
The separation of Helium gas from natural gas is challenging but highly important. MIL‐116(Ga), a “non‐porous” metal–organic framework is used as a molecular sieve to separate He from CH4. Druse‐like MIL‐116(Ga) particles are integrated into polysulfone mixed matrix membranes.
