Photopolymerization-based additive printing of functional inorganics has drawn great attention in recent years and one important challenge is the photoresin loading with diverse inorganics. Here, we introduce a Maillard reaction-derived laser lithography strategy for an unprecedented direct printing of diverse inorganic compounds. The sugar-assisted laser lithography(SLL) is powerful to carry choice metal ions and versatile for the generation of patterned inorganic materials comprising metal oxides,metal sulfides, and metal nitrides, characterized by ferroelectric, magnetic, semiconductivity, superconductivity, or other properties. The material architecture is flexibly manipulated by the laser intensity, power, printing speed, precursor solution, and computer-aided design to satisfy the practical requirements. This work demonstrates a new possibility for the further development of laser lithography in the directly printing of feature-rich inorganic materials and devices.

Cognitive neuroscience aims to develop computational models that can accurately predict and explain neural responses to sensory inputs in the cortex. Recent studies attempt to leverage the representation power of deep neural networks(DNNs) to predict the brain response and suggest a correspondence between artificial and biological neural networks in their feature representations. However, typical voxel-wise encoding models tend to rely on specific networks designed for computer vision tasks, leading to suboptimal brain-wide correspondence during cognitive tasks. To address this challenge, this work proposes a novel approach that upgrades voxel-wise encoding models through multi-level integration of features from DNNs and information from brain networks. Our approach combines DNN feature-level ensemble learning and brain atlas-level model integration, resulting in significant improvements in predicting whole-brain neural activity during naturalistic video perception. Furthermore, this multi-level integration framework enables a deeper understanding of the brain's neural representation mechanism, accurately predicting the neural response to complex visual concepts. We demonstrate that neural encoding models can be optimized by leveraging a framework that integrates both data-driven approaches and theoretical insights into the functional structure of the cortical networks.
