Radiation‐Resistant Aluminum Alloy for Space Missions in the Extreme Environment of the Solar System

open access: yesAdvanced Materials, EarlyView.
A novel ultrafine‐grained aluminum crossover alloy exhibits unprecedented radiation resistance and mechanical stability under extreme irradiation doses up to 100 dpa. The exceptional resilience arises from thermodynamically stable T‐phase precipitates, enabling lightweight structural materials for next‐generation spacecraft and extraterrestrial ...

The spirit of capitalism and long-run growth [PDF]

open access: yes
Why do different countries have different long-term savings and growth rates? Why is the productivity rate not the same around the world? Recent new theories of endogenous growth have tried to answer these questions by replacing the usual assumption of ...

Remote‐Controllable Immune‐Priming Spot Formation Via Nanocomplexed Hydrogel‐Assisted Histotripsy: Immunoasis

open access: yesAdvanced Materials, EarlyView.
A novel immunotherapeutic strategy combines injectable, adjuvant‐loaded hydrogels with externally controlled histotripsy to create immune‐priming sites within tumors. This approach generates millimeter‐sized immune‐activated lesions with flexible, patient‐tailored treatment scheduling, enabling precise immune activation through tumor ablation‐mediated ...

Book production and the onset of modern economic growth [PDF]

open access: yes
Endogenous growth theory suggests that human capital formation plays a significant role for the ‘wealth and poverty of nations.’ In contrast to previous studies which denied the role of human capital as a crucial determinant of for really long-term ...

Are there Diminishing Returns to R&D? [PDF]

open access: yes
Semi-endogenous models and, to some extent, also Schumpeterian models are based on the assumption of diminishing returns to R&D. This paper shows that the null hypothesis of constant returns to R&D cannot be rejected for the OECD countries.returns to R&D;
