Abstract Outdoor heat stress poses a serious public health threat and curtails industrial labor supply productivity, thus adversely impacting the wellness economy of entire society. With climate change, there will be more intense frequent waves that further present grand challenge for sustainability. However, an efficient economical method can provide localized outdoor cooling human body without intensive energy input is lacking. Here, novel spectrally selective nanocomposite textile...
Abstract Plasmon lasers can support ultrasmall mode confinement and ultrafast dynamics with device feature sizes below the diffraction limit. However, most plasmon-based nanolasers rely on solid gain materials (inorganic semiconducting nanowire or organic dye in a matrix) that preclude possibility of dynamic tuning. Here we report an approach to achieve real-time, tunable lattice plasmon lasing based arrays gold nanoparticles liquid materials. Optically pumped surrounded by molecules exhibit...
