Self – induced pulsed-mode emission in low-temperature inductively coupled arsenic-argon plasma

Frontiers in Physics
High-frequency inductively coupled radiation sources are widely used as light sources in applications requiring narrow and stable spectral emission lines, especially in the UV region, such as atomic absorption spectrometry.

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

FEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Mapping nanomechanical properties of live cells using multi-harmonic atomic force microscopy [PDF]

, 2011
The nanomechanical properties of living cells, such as their surface elastic response and adhesion, have important roles in cellular processes such as morphogenesis(1), mechano-transduction(2), focal adhesion(3), motility(4,5), metastasis(6) and drug ...

Capturing coherent pseudorotation through conical intersection in photoionized benzene

Nature Communications
Vibronic coupling and coherence are crucial in the charge and energy transfer of photoexcited molecules. Here we investigate the coupled electron-nuclear dynamics of the photoionized benzene molecule using the time-resolved Coulomb-explosion imaging ...

Atomic partial wave meter by attosecond coincidence metrology

Nature Communications, 2022
Understanding the photoelectron emission time after the interaction of photon with atoms and molecules is of fundamental interest. Here the authors examine the role of partial waves to the photoionization phase shift of atoms using an attosecond clock ...

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

FEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

Loss of IGF‐1R impairs DNA‐PKcs recruitment to chromatin leading to defective end‐joining

Molecular Oncology, EarlyView.
IGF‐1R promotes radioresistance by facilitating DNA‐PKcs recruitment to chromatin, enabling non‐homologous end‐joining (NHEJ) repair of double‐strand breaks. Inhibition or loss of IGF‐1R disrupts this recruitment to damage sites, driving compensatory reliance on microhomology‐mediated end‐joining (MMEJ) repair.

In Situ Micro-XRD Methods for Identifying Glass and Minerals in Extraterrestrial Samples

, 2022
Glass or amorphous state materials are vital components of lunar regolith and have attracted considerable attention. The analytical data on the texture and structure of glassy and crystallized materials can be used to reconstruct the geological history ...
