Design of an open-shell nitrogen-centered diradicaloid with tunable stimuli-responsive electronic properties

Communications Chemistry, 2022
The electronic structures and open-shell diradical character of organic diradicaloids endow them with potentially useful optical, electronic and magnetic properties.

Atomic and Molecular Processes at Solid Surfaces [PDF]

Journal of Colloid and Interface Science, 1977
Abstract Development of new techniques over the past 15 years permits the investigation of the structure, the composition, and reactivity of solid surfaces on the atomic scale. Our present knowledge of the structure of clean surfaces and of adsorbed monolayers as studied by low-energy electron diffraction is reviewed. Surface crystallography provides

Organoids in pediatric cancer research

FEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Fine and hyperfine (de-)excitation of C4H (X2Σ+) by collisions with He at low temperatures

Astronomy & Astrophysics
We present a quantum scattering study of the fine and hyperfine rotational (de-)excitation of the linear carbon-chain radical C4H (X2Σ+) in collisions with helium atoms at low temperatures relevant to the interstellar medium (ISM).

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

The Nucleated Atomistic Grain Growth Simulator (NAGGS): application to the size-dependent structural and physical properties of nanosilicate dust

Astronomy & Astrophysics
Context. The essential physics of dust grains are typically rationalised using phenomenological approaches, often assuming highly simplified grain morphologies.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

In situ characterization of volatile and refractory hydrocarbons produced by UV photolysis of interstellar C2H2 ice

Astronomy & Astrophysics
Context. Acetylene (C2H2) has been commonly observed in various astronomical objects, including star-forming regions, young stellar objects, and our Solar System.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Methanimine as a sink in the HCN and HNC solid state hydrogenation network

Astronomy & Astrophysics
Aims. We aim to provide a systematic and quantitative description of the hydrogenation network connecting HCN and HNC to methylamine on interstellar water ices, and to identify the dominant reaction pathways and potential bottlenecks. Methods.
