Abstract Understanding the function of a biomolecule hinges on its 3D conformation or secondary structure. Chirally sensitive, optically active techniques based differential absorption UV–vis circularly polarized light excel at rapid characterisation structures. However, Raman spectroscopy, powerful method for determining structure simple molecules, has limited capacity structural analysis biomolecules because intrinsically weak optical activity, necessitating millimolar (mM) sample...
Strong dipoles in molecular HTMs can cause energetic disorder, leading to reduced mobility. This be counteracted by a preferential antiparallel dipole ordering brought about intermolecular hydrogen bond-assisted pairing.
Nanophotonic platforms in theory uniquely enable < femtomoles of chiral biological and pharmaceutical molecules to be detected, through the highly localized changes asymmetries near fields that they induce. However, current nanophotonic based strategies are intrinsically limited because rely on far field optical measurements sensitive a much larger volume, than influenced by molecules. Consequently, depend detecting small response restricting detection sensitivities. Here, we exploit an...
Utilising normal incidence X-ray standing waves we rigourously scrutinise the "inverted model" as adsorption structure of free-base tetraphenyl porphyrin on Cu(111). We demonstrate that iminic N atoms are anchored at near-bridge sites surface displaced laterally by 1.1 ± 0.2 Å in excellent agreement with previously published calculations.
Titanium electrodes bearing the naturally-forming native oxide coating are competent for electroreduction of oxalic acid to glyoxylate and glycolate.
Single-layer two-dimensional (2D) nanomaterials exhibit physical and chemical properties which can be dynamically modulated through out-of-plane deformations. Existing methods rely on intricate micromechanical manipulations (e.g., poking, bending, rumpling), hindering their widespread technological implementation. We address this challenge by proposing an all-optical approach that decouples strain engineering from complexities. This method leverages the forces generated chiral light beams...
Surface treatment of perovskite materials with their layered counterparts has become an ubiquitous strategy for maximizing device performance. While confer great benefits to the longevity and long‐term efficiency resulting stack via passivation defects surface traps, numerous reports have previously demonstrated that these evolve under exposure light humidity, suggesting they are not fully stable. Therefore, it is crucial study behavior in isolation conditions mimicking a stack. Here, shown...
Abstract The adsorption configurations of a technologically relevant model organic adsorbate on the silicon (001) surface were studied using energy scanned x-ray photoelectron diffraction (PhD). Previous work has established existence an interesting vertically-aligned (‘flagpole’) configuration, where acetophenone attaches to Si(001) via acetyl group carbon and oxygen atoms. Density functional theory calculations have predicted two energetically similar variants this structure, phenyl ring...
Abstract In the era of next generation electronic technologies, pursuit reconfigurable circuitry is one key strategies for enhancing performance and functionality. The prevailing approach involves utilising individual components with dual functionality to provide reconfigurability. While valuable, this method remains an interim solution, necessitating a platform recurrent redesign tailored specific tasks. realisation technological leap hinges on spatially resolved, dynamic manipulation...
