Bias‐Free Highly Efficient and Stable Dye‐Sensitized Photoelectrochemical Cells via Cascade Charge Transfer

Advanced Functional Materials, EarlyView.
A buried‐junction DSPEC design is introduced that leverages cascade charge transfer to enhance efficiency, stability, and versatility. This approach facilitates effective charge transfer and minimizes recombination losses, leading to significant improvements.

Intermolecular Interactions as Driving Force of Increasing Multiphoton Absorption in a Perylene Diimide‐Based Coordination Polymer

Advanced Functional Materials, EarlyView.
This study uncovers the unexplored role of intermolecular interactions in multiphoton absorption in coordination polymers. By analyzing [Zn2tpda(DMA)2(DMF)0.3], it shows how the electronic coupling of the chromophores and confinement in the MOF enhance two‐and three‐photon absorption.

Understanding and Optimizing Li Substitution in P2‐Type Sodium Layered Oxides for Sodium‐Ion Batteries

Advanced Functional Materials, EarlyView.
This work explores Li‐substituted P2 layered oxides for Na‐ion batteries by crystallographic and electrochemical studies. The effect of lithium on superstructure orderings, on phase transitions during synthesis and electrochemical cycling and on the interplay of O‐ versus TM‐redox is revealed via various advanced techniques, including semi‐simultaneous

INFORMATION STORAGE SYSTEM

Cybernetics and Systems, 2010
This paper examines an Information Storage System (ISS), in which a vocabulary and set of experimental data are defined, on the basis of which both linear and linearized (meaning that they are treated in linear fashion) mathematical models are generated.

Information Storage

2010
The success of information transfer from the suppliers depends largely up on the organization of the data to cater for different categories of the users. It calls for quick, competitive and cost effective solutions. To meet the same, hierarchical data representation is introduced in this chapter.

Cortical rewiring and information storage

Nature, 2004
Current thinking about long-term memory in the cortex is focused on changes in the strengths of connections between neurons. But ongoing structural plasticity in the adult brain, including synapse formation/elimination and remodelling of axons and dendrites, suggests that memory could also depend on learning-induced changes in the cortical 'wiring ...

Molecules for information storage

Journal of Magnetism and Magnetic Materials, 2002
Abstract Possibility of conformation change by external electric field of synthesized fullerene organometallic cycloadducts C 60 ONCFn and C 60 CH 2 NCH 3 CHFn is discussed using semiempirical quantum chemical calculations. The calculations are intended to find out if molecules may be used for information storage.
