Einstein's grandchildren [PDF]

open access: yesEMBO reports, 2010
The new German government has boldly promised to “lead Germany to first place in the world in education, science and research.” Howy Jacobs explores this promise and whether it will lure Einstein's grandchildren back across the pond.

Crystallization Dynamics of Hybrid Perovskite Mediated by a Biopolymer: From Precursor Solution to Thin Film

open access: yesAdvanced Materials Interfaces, EarlyView.
In order to better understand the complex crystallization dynamics of starch‐assisted metal halide perovskites (MHPs), the properties of colloidal precursor suspensions and the thermodynamic evolution of the crystallization reaction are investigated by a comprehensive set of characterization techniques, from solutions to films.

On gradient η-Einstein solitons

open access: yes, 2018
If the potential vector field of an η-Einstein soliton is of gradient type, using Bochner formula, we derive from the soliton equation a nonlinear second order PDE.

Supergravity and In‐Situ Evaporation Induced Well‐Aligned and Self‐Crosslinked 2D Material‐Based Thin Films

open access: yesAdvanced Materials Interfaces, EarlyView.
The supergravity and in‐situ evaporation are utilized to produce GO thin films with a record‐high mechanical strength of 540 MPa. The supergravity confines the 2D flakes within a very thin layer and creates a large all‐directional shear stress to induce the superalignment, while in‐situ evaporation accelerates the dehydration and facilitates the ester ...

Einstein’s Gyros

open access: yesPhysics in Perspective, 2019
Einstein’s life-long effort to develop a theory that unifies gravitation and electromagnetism was not a purely theoretical enterprise. The technical environment of a gyrocompass factory triggered his search for a novel connection between the rotation of an electrically uncharged body and its magnetic field. The dimensional equality of the electric unit

Einstein e a Filosofia [PDF]

open access: yesRevista Brasileira de Ensino de Física, 2006
Albert Einstein teve, ao longo de sua vida, um intenso envolvimento com a Filosofia e com filósofos da ciência, fato que marcou de maneira profunda seu modo de fazer Física. Discutimos neste artigo alguns pontos basilares deste seu envolvimento e de seu texto "Física e Realidade".

Femtosecond Pulse Shaping with Semiconductor Huygens' Metasurfaces

open access: yesAdvanced Optical Materials, EarlyView.
Spatially variant silicon Huygens' metasurfaces enable femtosecond pulse shaping by tailoring the spectral phase and amplitude of incident pulses. Two key functionalities are demonstrated: temporal stretching and pulse splitting of an input Gaussian pulse.
