Transient absorption in inorganic systems

, 2022
ransient absorption spectroscopy is one the most popular methods to study photochemistry and photophysics. This technique allows observation of the dynamics in the electronic excited states after photoexcitation over a wide range of timescales, from the femtosecond to the millisecond timescales.

CCDC80 suppresses high‐grade serous ovarian cancer migration via negative regulation of B7‐H3

Molecular Oncology, EarlyView.
PAX8 is a lineage‐specific master regulator of transcription in high‐grade serous ovarian cancer (HGSC) progression. We show for the first time that PAX8 facilitates proliferation and metastasis by repressing the cell autonomous tumor suppressor CCDC80 and inducing B7‐H3 expression.

Ultrafast Excited State Dynamics of a Verdazyl Diradical System

Photochem
While the photophysics of closed-shell organic molecules is well established, much less is known about open-shell systems containing interacting radical pairs.

A Fast Transient Absorption Study of Co(AcAc)3 [PDF]

Frontiers in Chemistry, 2019
The study of transition metal coordination complexes has played a key role in establishing quantum chemistry concepts such as that of ligand field theory. Furthermore, the study of the dynamics of their excited states is of primary importance in determining the de-excitation path of electrons to tailor the electronic properties required for important ...

Intestinal barrier function and absorption in pigs after waeaning: a review

, 2011
Under commercial conditions, weaning of piglets is associated with social, environmental and dietary stress. Consequently, small-intestinal barrier and absorptive functions deteriorate within a short time after weaning.

Probing ultrafast dynamics with attosecond transient absorption [PDF]

, 2015
The broad bandwidth of an isolated attosecond pulse excites a vast number of states simultaneously, and the corresponding absorption features can be monitored with exceptional temporal resolution.

CD47 promotes mitogen‐activated protein kinase and epithelial‐to‐mesenchymal transition molecular programs to drive prometastatic phenotypes in non‐small cell lung cancer

Molecular Oncology, EarlyView.
Beyond its role in immune evasion, this study identified that CD47 drives tumor‐intrinsic signaling in non‐small cell lung cancer (NSCLC). Transcriptomic profiling and functional studies revealed that CD47 regulates cell adhesion, migration, and metastasis through an ERK–EMT signaling axis.

Time-Resolved Spectroscopic Study of N,N-Di(4-bromo)nitrenium Ions in Selected Solutions

Molecules, 2018
Nitrenium ions are important reactive intermediates in chemistry and biology. In this work, femtosecond and nanosecond transient absorption (fs-TA and ns-TA) along with nanosecond time-resolved resonance Raman (ns-TR3) experiments were employed to ...

Transient absorption spectroscopy

, 2021
Die optischen Eigenschaften von organischen Farbstoffen und optisch aktiven anorganischen Molekülen werden durch ihre chemische Struktur, ihrer chemischer Umgebung, und durch das Verhalten ihrer angeregten Zustände bestimmt. Die klassischen Methoden zur Untersuchung dieser Eigenschaften sind die Absorptions- und Lumineszenzspektroskopie.
