Inverse Design of Nanoparticulate Materials

open access: yesAdvanced Materials, EarlyView.
Inverse design shifts nanomaterial development from empirical trial‐and‐error to predictive model‐driven strategies. It can rely on knowledge‐based, data‐based, or hybrid process and property functions. This perspective article provides a practical framework for applying inverse design based on instructive examples. It discusses which modeling approach

Sub‐nm2 Ferroelectric Domains via Charged 180° Walls in ZrO2

open access: yesAdvanced Materials, EarlyView.
Ferroelectric ZrO2${\rm ZrO}_2$ thin films host closely spaced charged 180∘$^{\circ }$ domain walls that vertically compress polar domains beyond their lateral half‐unit‐cell limit. These head‐to‐head and tail‐to‐tail walls show distinct bulk‐like structures, natural oxygen‐mediated stabilization, and highly asymmetric mobility, highlighting new ...

Percolation‐Driven β‐Relaxation Enables Resonant Acceleration of Crystallization in Amorphous Phase‐Change Materials

open access: yesAdvanced Materials, EarlyView.
Mobile‐atom percolation underlying β‐relaxations fundamentally dictates the crystallization pathways of phase‐change materials. High‐frequency ultrasonic excitation dynamically modulates this critical mobility percolation network, substantially accelerating the crystallization process.

Nonplanar Bouligand Architectures for Enhanced Mechanical Performance in Cementitious Composites

open access: yesAdvanced Materials, EarlyView.
Inspired by the impact region of the Mantis shrimp dactyl club, nonplanar additive manufacturing translates sinusoidal Bouligand architectures into cementitious composites. Printing‐induced anisotropy and architected interfaces promote distributed damage and arrest crack propagation, enhancing strength and energy absorption.

A Critical Call for Mechanistic Investigations of Metal‐Bacteria Interactions

open access: yesAdvanced Materials, EarlyView.
It is well established that the antibacterial properties of metals have tremendous importance for bioengineering applications. What is not as appreciated, however, is the reproducibility crisis in this field's vast literature. In this perspective, we highlight this reproducibility problem, discuss its sources, and suggest solutions towards focused ...

Consequences of head size following trauma to the human head

open access: yesJournal of Biomechanics, 2002
The objective of the present study was to evaluate whether variation of human head size results in different outcome regarding intracranial responses following a direct impact. Finite Element models representing different head sizes and with various element mesh densities were created.

Estimation and representation of head size (people overestimate the size of their head – evidence starting from the 15th century)

open access: yesBritish Journal of Psychology, 2008
The head is a special part of our body since we do not see it directly. Four experiments were conducted to verify what healthy people know about the size of their head. As a control, we used the accuracy in estimating other people's heads (in all the experiments) and the estimation of the size of another part of the body, the hand (in Experiment 4 ...

Head Size and Intelligence

Pediatrics, 1982
We would like to raise some of the more obvious questions about the procedures and conclusions in the article by Lipper et al (Pediatrics 67:502, 1980) relating head circumference at birth to neurobehavioral outcome. One criterion stated for inclusion of an infant in the study was a birth weight less than the tenth percentile.

Head size and schizophrenia

Schizophrenia Research, 2002
There is a small but intriguing body of literature which suggests that head size may be reduced in patients with schizophrenia. This literature sits alongside more substantial and compelling evidence that there is a reduction in cerebral volume in schizophrenia.

Practical supergrain head sized arrays

1997 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2002
This paper carried out a new design of head sized sensor arrays with a simple delay-and-sum beamforming which provides useful amounts of directivity index with sufficient robustness to errors. A frequency-independent sidelobe reduction is proposed to achieve optimal frequency characteristics.
