Storage of Information Using Periodic Precipitation

Abstract

In the present work, transparent flexible thin polymer films with silver patterns have been created. The resulting structures made by the printing method represent a new alternative approach for recording, protecting, and transmitting information as well as for nonlinear gradient material formation. An alphabet for process automatization was created, and an automated system for recording and reading information was developed. To protect the information, we suggest the usage of a classic XOR function: the idea of scrambling is to demonstrate the simple and clear example of coding the ITMO University logo, and the code is provided. Additionally, the resulting samples are functional gradient materials with peaks of surface plasmon resonance. In the following, automated peak decoding by UV−vis spectroscopy allows an additional physicochemical method for structure decoding.

Current and emerging opportunities in biological medium‐based computing and digital data storage

“…Nenashkina et al. [ 117 ] presented a new alternative approach for recording, protecting, and transferring data. They created a transparent flexible thin polymer film with silver diffraction patterns to produce four Liesegang rings (LR) utilizing the Liesegang phenomena.…”

“…Another approach, similar to encoding in oligomers, is based on monomethoxypolyethylene glycol (mPEG) and reading using MALDI-TOF MS signals. [116] Nenashkina et al [117] presented a new alternative approach for recording, protecting, and transferring data. They created a transparent flexible thin polymer film with silver diffraction patterns to produce four Liesegang rings (LR) utilizing the Liesegang phenomena.…”

Precise Evaluation of Spatial Characteristics of Periodically Precipitating Systems via Measurement of RGB (Red, Green, and Blue) Values of Pattern Images

“…1 LB are distinct and mechanically separable precipitate bands with numerous applications such as in micro-and nanotechnology, 2 protein crystallization, 3 and information storage. 4 Classical Liesegang experiments consist of a heterogeneous system with three components, two reactants, and a gel that acts as a medium through which diffusion occurs. A gel that is set with one of the reactants (A) and uniformly disperses into it is called an inner electrolyte.…”

Immersive Molecular Dynamics in Virtual Reality: Increasing Efficiency of Educational Process with Companion Converter for NarupaXR

“…Due to the rapid development of computer technologies, more attention is paid to the areas of their intersection with chemistry, including infochemistry [ 1 , 2 , 3 , 4 ]. In order to prepare the 21st century students to be successful researchers and engineers in emerging fields of chemistry, informatics and programming, it is necessary to provide more educational tools to ensure deeper understanding of the fundamental principles in the aforementioned areas.…”
