Precipitation‐Modulated Harmonic Architectures Enable Superior Strength–Ductility Synergy from Cryogenic to Elevated Temperatures in Nanostructured Alloys

Advanced Science, EarlyView.
Precipitation‐modulated recrystallization enables a programmable bimodal harmonic architecture in a high‐entropy alloy, delivering 1–2 GPa yield strength with >10% ductility from −196 °C to 700 °C. The resulting broad‐temperature robustness arises from the synergy of dual‐mode nanoprecipitation, harmonic core–shell topology, and temperature‐adaptive ...

Measurements of Helium Excitation in Be⁺-He and Mg,⁺-He Collisions

, 1987
We have observed level specific excitation of He(n = 2, 3) in collisions of Be+ and Mg+ with He at projectile velocities of 1 2 a.u. With both Be+ and Mg+ projectiles, excitation for small scattering angles (large impact parameters) is appreciable ...

A Dual‐Channel Synergistic Ultrasensitive Biosensor for Tumor Liquid Biopsy

Advanced Science, EarlyView.
ABSTRACT Liquid biopsy technology, which detects circulating tumor DNA (ctDNA) in cerebrospinal fluid, plays a crucial role in the early diagnosis and precision treatment of gliomas. However, the intrinsically low abundance and rapid clearance of ctDNA pose substantial challenges for conventional analytical techniques, such as droplet digital PCR and ...

Hypergolic Copper Cluster‐Based Covalent Organic Frameworks

Advanced Science, EarlyView.
Hpergolic cluster‐based covalent organic framework (Cu3‐CB‐COF), assembled from aldehyde‐functionalized carborane monomers and trinuclear copper clusters, demonstrates a strong synergy between its catalytic copper nodes and energetic carborane backbones.

Engineering tool for the evaluation of global IED effects

Defence Technology, 2016
The detonation of an IED near a military vehicle induces different damage effects on the vehicle and its occupants. There are local effects from fragments and projectiles but there are also global effects from a momentum transfer on the complete vehicle ...

Diffraction In The Binary Encounter Electron Peak Observed In Collisions Of 0.6 MeV Amu⁻¹ I7+, I23+ And Au11+ Projectiles With He And Ar

, 1992
Relative double differential cross sections for electron emission from collisions of 0.6 MeV amu-1I7+and I23+ projectiles with Ar and Au11+projectiles with He were measured for electron energies from 100 eV to 2000 eV and for angles from 0° to 50 ...

Linking community structure and climate vulnerability in desert plant assemblages of southern California

American Journal of Botany, EarlyView.
Abstract Premise Desert plant assemblages in southern California provide an opportunity to link patterns of community structure with climate‐driven vulnerability in a rapidly changing environment. California sustains an exceptionally diverse flora of approximately 4300 plant species, with 31% identified as endemic.

Single Ionization with Dressed Projectiles: An Improved Theory for Both Long- and Short-Range Interactions

Atoms
In this work, we present a theoretical model to investigate electron emission in collisions between dressed ions with He atoms and H2 molecules. The projectile potential is described as the sum of a long- and short-range terms.

Total reaction and 2n-removal cross sections of 20-60A MeV He-4,He-6,He-8, Li-6-9,Li-11, and Be-10 on Si

, 1996
Total reaction cross sections, sigma R, of 20-60A MeV He-4,He-6,He-8, Li-6-9,Li-11, and Be-10 were measured by injecting magnetically separated, focused, monoenergetic, identified secondary beams of those projectiles into a Si detector telescope and ...

Correction of Ineffective Erythropoiesis and Normalization of Iron Homeostasis After Exagamglogene Autotemcel in Transfusion‐Dependent β‐Thalassemia

American Journal of Hematology, EarlyView.
ABSTRACT Exagamglogene autotemcel (exa‐cel) is a one‐time, ex vivo, CRISPR‐Cas9 gene edited cell therapy approved for patients with transfusion dependent β‐thalassemia (TDT) aged 12–35 years. In a Phase 3 study (CLIMB THAL‐111), exa‐cel treatment resulted in reactivation of fetal hemoglobin and increases in total hemoglobin, leading to transfusion ...
