Understanding how photoexcited aromatic molecules redistribute energy is central to determining whether excitation leads to photostable relaxation or bond-selective chemistry. Anisole is a model methoxy-substituted aromatic in which bound ππ^states coexist with dissociative πσ^states along the O-CH3 coordinate. Its structured near-ultraviolet absorption band supports bound vibronic levels,¹...

ZnO is a multifunctional transparent conductive oxide (TCO) with many scientific and technologic uses. They include, among others, applications in biomedicine, photonics, sensing or photocatalysis. These applications could benefit in many cases from the use of large-area, electrically anisotropic surfaces (i.e. optically transparent surfaces with alternating highly conductive and highly...

The electrochemical surface-enhanced Raman spectra (SERS) of 1,4-bis(4-vinylpyridyl)benzene (bvpb) recorded on silver electrodes at different potentials, using three excitation wavelengths (785, 532, and 473 nm), reveal the presence of a resonance process at negative potentials under 785 nm excitation. This process leads to the appearance of two strongly enhanced SERS bands at ca. 1500 and...

Currently, conventional particle accelerators, such as cyclotrons or linear accelerators, can accelerate charged particles to extremely high energies, and are therefore fundamental in applications including hadron therapy, and radioisotope production for medical diagnostics. However, the acceleration gradients in these systems are typically limited to values on the order of tens of MV/m,...

At the heart of any light-harvesting technology, such as artificial photosynthesis or photovoltaics, lie the fundamental steps of photoinduced charge transfer and separation, which are best optimized by combining electron donor and acceptor materials into molecular dyads. In these architectures, the donor and acceptor units are integrated into a single molecule and linked by a π-conjugated...

Among the different techniques to modify materials at the surface level, laser micromachining offers a versatile working route to alter the topography of a target in the micrometric scale. Femtosecond pulsed laser ablation (fs PLA) leads to minimal debris outcomes in comparison to longer pulse technologies, such as pico or nanosecond PLA. The briefness of the interaction conferred by fs PLA...

The polarization state of few-cycle laser pulses plays a fundamental role in light–matter interactions, governing phenomena such as optomagnetic effects, high-harmonic generation, and coherent control. Accurate characterization of the time-dependent polarization of ultrashort pulses is therefore essential for both optimizing these applications and gaining insight into the underlying physical...

Silicon’s exceptional optical and electrical properties, combined with its high purity, crystal quality, abundance and low price makes it the main standard for developing new micro- and nanoscale technologies in electronics and photonics [1]. In this work, we present a novel application: the formation of vibrating microcavities by irradiating a Si (111)-oriented wafer covered with a...

Understanding how molecular organization in solution governs excitonic coupling and structure in conjugated polymer nanostructures remains a central challenge in soft condensed matter physics. Here, we show that controlled solution-state pre-assembly of poly(3-hexylthiophene) (P3HT) prior to nanoparticle (NP) formation enables tuning of intrachain and interchain interactions, with direct...

The photodissociation of alkyl iodides has long served as a benchmark for understanding nonadiabatic molecular dynamics following ultraviolet excitation1. Allyl iodide provides an interesting extension to this family owing to the resonance stabilization of the allyl radical, which is expected to modify the excited-state potential energy landscape and influence the dissociation mechanism....
