Negative refraction and plano-concave lens focusing in one-dimensional photonic crystals
Negative refraction is demonstrated in one-dimensional (1D) dielectric photonic crystals (PCs) at microwave frequencies. Focusing by plano-concave lens made of 1D PC due to negative refraction is also demonstrated.

A millimeter-wave antireflection coating for cryogenic silicon lenses [PDF]
We have developed and tested an antireflection (AR) coating method for silicon lenses at cryogenic temperatures and millimeter wavelengths. Our particular application is a measurement of the cosmic microwave background.

Laser‐assisted synthesis enables rapid (within 1 h) and high‐yield (≥90%) production of Co‐MOFs with mesoporous structures, tunable magnetic and optical properties, and efficient adsorption of N2, CH4, and CO2 for low‐energy gas separation. DFT calculations elucidate the electronic structure and adsorption behavior.

Habilidades matematicas para el buen desempeño del ingeniero [PDF]
Como se conoce el estudio de las habilidades es un fenómeno que puede centrarse desde distintos ángulos, pero: en este sentido siempre serán insuficientes. La verdadera dimensión de las habilidades es integral, sistemática y compleja. Varios autores como

O PLANO REAL E A REPÚBLICA RENTISTA
A exposicao que segue demonstra um dos problemas estruturais sobre os quais a economia brasileira se estabeleceu a partir da execucao do ultimo grande plano de estabilizacao, a saber, o Plano Real. A partir dai, ver-se-a que o modelo de estabilizacao referido nunca trouxe o prometido desenvolvimento sustentavel, a despeito da sua eficacia no combate a ...

Operando real‐time current density–voltage absorption spectroscopy visualizes spatial phase evolution in mixed‐halide perovskites from device to module scale. Phase instability preferentially initiates in regions with insufficient carrier extraction, revealing electrical boundary conditions as governing factors.

Death of mixed methods?: Or the rebirth of research as a craft [PDF]
The classification by many scholars of numerical research processes as quantitative and other research techniques as qualitative has prompted the construction of a third category, that of ‘mixed methods’, to describe studies that use elements from both ...
