Tailoring Light Management in All‐Perovskite Tandem Solar Cells: The Impact of Nanotextures

open access: yesAdvanced Functional Materials, EarlyView.
To further improve the power conversion efficiency of all‐perovskite tandem solar cells, light management strategies need to be implemented. Front‐sided nanotextures reduce reflection losses, which boosts light absorption, thus increasing the tandem JSC, which is further supported by reducing parasitic absorption.

Sky‐Directional Radiative Cooling Meta‐Films for Daylighting Windows

open access: yesAdvanced Functional Materials, EarlyView.
A geometry‐mediated microprism meta‐film enables transparent, sky‐directional radiative cooling for daylighting windows. By decoupling control of visible transmittance from mid‐infrared emissivity, ground‐emitted heat absorption is suppressed while skyward heat dissipation is enhanced.

Constraints in spatial structures

Proceedings of the sixteenth ACM conference on Hypertext and hypermedia, 2005
People have become used to paper as an information carrier over thousands of years. Paper is usually easy to handle and has been adopted as a metaphor for information structures in computer applications. This article gives a brief overview of our analysis on real world bindings.

Crystal structure refinement with constraints

Computers & Chemistry, 1978
Abstract A program for least-squares refinement of crystal structures, which imposes various kinds of constraints on the parameters, is shown and discussed. Such constraints are particularly useful when a molecule can be considered as a rigid body or a ‘segmented-rigid’ body: in most of these cases, molecular non-crystallographic symmetry can be ...

Structural constraints on language

Reti, saperi, linguaggi, 2014
Recently, in cognitive sciences the debate moved on from the analysis of the inner procedures of mental events to the analysis of the way the sapiens know and represent the world through the evolutionary and biological perspective. The biological approach to the study of human language implies a significant change to the way we can interpret language ...

Fuzzy clustering with structural constraints

Fuzzy Sets and Systems, 1999
Abstract In this paper we propose a generalization of the standard clustering problem, which we call Structural Constrained Clustering (SCC) problem. In SCC problem, the cluster interconnections are given by a binary relation R. If this relation is empty then SCC problem reduces to the standard classification problem. The cluster structure imposed by
