"When something is said to be impossible, there are two points for researchers to initially clarify: whether it really is forbidden by the laws of nature; or whether it is simply that no material that currently exists in nature can do that." Metamaterials are such magical beings, which have physical properties like invisibility, negative refraction, super-resolution, and perfect absorption that are absent from natural materials. It has been rated by Science as one of the top ten scientific and technological breakthroughs affecting human beings in the 21st century.

A real-time adaptive optics system was developed, characterised and applied to measure the 3D flow field through an oscillating surface of a water drop on an opaque Gas Diffusion Layer. A case study shows that the system corrects successfully measurement errors of the flow field that are caused by the refraction of light at the time-varying water-air interface.

A recent study has uncovered how the pathogen Ralstonia solanacearum disrupts plant defenses through its type III effector RipAF1. The research shows that RipAF1 modifies a critical plant protein, FBN1, via ADP-ribosylation, which alters the plant’s hormonal signaling balance, suppressing jasmonic acid (JA) and enhancing salicylic acid (SA) pathways.

Traditional optical anti-counterfeiting (AC) is achieved by static printed images, which makes them susceptible to lower levels of security and easier replication. Here in, we fabricated a multifunctional anti-counterfeiting (AC) device based on fluorescent electrophoretic particles, which can achieve dynamic AC display by switching the electric field and UV light. This work demonstrated that fluorescent electrophoretic display (EPD) has a fast response, dynamically switch image and bright luminescence, providing potential in multifunctional AC applications.
