Nowadays, corruption scandals are rampantly and with increasing intensity exposing the misuse of public resources and the actions of dishonest public administrators. The use of scarce public resources has not allowed the hoped-for objectives to be reached. Even with no illegal act has been committed (here using the traditio-nal concept of illegality in Public Administration), it is not possible to ensure that public resources bring about the benefits expected by the population. With increasing frequency, the issue of control over public resources emerge. Consequently, local legislations and Admi-nistrative Law students look to create solutions to ensure Public Ad-ministration’s smoothness and the proper use of public resources, in order to create an environment that allows the collective purposes which justifies State collection of resources. However, the solutions in terms of control that come and are presented, cannot consider a sce-nario not present in Administrative Law, based on long-extinct struc-tures. If control is a tool destined to solve a problem, it seems funda-mental that this tool be in accordance with its field of application. It would be pointless to create a repair instrument that is useless for the damaged property’s characteristics. In this context, a discussion is formulated regarding the internal control of Public Administration. It follows that, in the control system of Administration itself and not by organs outside its organic structure, internal control is going through modifications and doctrinal discussions that aim to update it—althou-gh many times in disregard of the current Administration’s concept, structures and modus operandi. KEY WORDS: administration, internal control, public administration, effectiveness, purpose JEL CODE: H52, H72 RESUMENEn la actualidad, cada vez con mayor intensidad, pululan escándalos de corrupción que exponen el mal uso de recursos públicos y la acción de administradores públicos deshonestos. De la misma manera, el empleo de los escasos recursos públicos no ha permitido alcanzar los objetivos esperados. Es decir, incluso sin la comisión de cualquier acto ilí­cito (utilizando aquí­ el concepto tradicional de ilegalidad en la Administración Pública), no se logra asegurar que los recursos públicos traigan los beneficios esperados por la población. Cada vez con mayor frecuencia emerge el tema del control de los recursos públicos. Como consecuencia, las legislaciones locales y los estudiosos del Derecho Administrativo buscan crear soluciones para garantizar la lisura de la Administración Pública y el buen uso de los recursos públicos, con el fin de crear un entorno que permita realizar las finalidades colectivas justificantes de la recaudación de recursos por el Estado. Sin embargo, las soluciones en materia de control que vienen y que se presentan, no pueden considerar un escenario inexistente en el Derecho Administrativo, basado en estructuras hace tiempo extinguidas. Si se considera que el control es una herramienta destinada a resolver un problema, nos parece fundamental que esta herramienta esté de acuerdo con su campo de aplicación. De nada adelantarí­a formular un instrumento de reparación que resulte inútil para las caracterí­sticas del bien dañado. En ese contexto, se plantean discusiones acerca del control interno de la Administración Pública. En el sentido de que, el sistema de control realizado por la propia Administración y no por órganos fuera de su estructura orgánica, el control interno viene pasando por modificaciones y discusiones doctrinales que tienen como objetivo actualizarlo, aunque muchas veces en desconsideración del concepto, de las estructuras y del modus operandi de la Administración actual.

The transient optical response of multiresonant all‐dielectric nanoantennas via a combination of broadband ultrafast reflectivity experiments and nonlinear optics nanoscale modeling is studied. Ultrafast all‐optical control of the reflectivity is demonstrated in variably sized Al.18Ga.82As nanoantennas over four distinct Mie resonances (including Fano‐like resonances), spanning a broad spectral range, from the red to the near‐infrared. A spatially inhomogeneous dynamical model, which accounts for diffusion of the photogenerated carriers inside the semiconductor, is introduced and exploited to isolate the physical phenomena leading to the overall transient response, namely, Drude plasma formation and Pauli blocking following band filling and thermo‐optical effect. The results pave the way to the development of multiwavelength all‐optically reconfigurable filters for next‐generation ultrafast add/drop multiplexing.

Diatomaceous earth, or diatomite, is produced through the accumulation of diatom (Bacillariophyceae) skeletons (i.e. cell walls called frustules) made of amorphous silica. The porous, highly symmetrical structure and microscopic size of diatom cell walls make them ideal constituents of sensing devices and analytical chips. Here, we propose chemical methods to purify diatom frustules extracted from diatomaceous earth. Using photo deposition techniques, we grow gold nanoparticles on the surface of diatom skeletons and within the pores of the skeletons, where the size and density of nanoparticles can be controlled by changing the parameters of the synthesis. Resulting devices have an internal porous structure that can harvest molecules from a solution, and an external shell of gold nanoparticles that amplifies the electromagnetic field generated by the measurement laser in Raman or other spectroscopies. The combination of these effects enables the analysis of biological specimens, chemical analytes and pollutants in extremely low abundance ranges. The devices were demonstrated in the analysis of Bovine Serum Albumin in water with a concentration of 100 aM, and mineral oil with a concentration of 50 ppm.

Ultrafast nanophotonics is an emerging research field aimed at the development of nanodevices capable of light modulation with unprecedented speed1–4. A promising approach exploits the optical nonlinearity of nanostructured materials (either metallic or dielectric) to modulate their effective permittivity via interaction with intense ultrashort laser pulses. Although the ultrafast temporal dynamics of such nanostructures following photoexcitation has been studied in depth5, sub-picosecond transient spatial inhomogeneities taking place at the nanoscale have been overlooked so far. Here, we demonstrate that the inhomogeneous spacetime distribution of photogenerated hot carriers induces a transient symmetry breaking in a highly symmetric plasmonic metasurface. The process is fully reversible and results in a broadband transient dichroism with a recovery of the initial isotropic state in less than 1 ps, overcoming the speed bottleneck caused by slower (electron–phonon and phonon–phonon) relaxation processes. Our results pave the way to ultrafast dichroic devices for high-speed modulation of light polarization. Inhomogeneity of the photogenerated carrier spacetime distribution enables transient symmetry breaking in a metasurface. As a result, broadband transient dichroism is demonstrated.
