Region-selective chemical modification of nano- and microstructures can unlock a world of novel functional surfaces. However, this small scale makes region selectivity challenging, especially on homogeneous and chemically inert synthetic structures. Here, we report the one-step dynamic synthesis of heterogeneous multicomponent hybrid silicone nanorods (MCH-SNRs). These nanorods bear specific modifiable regions that can be assigned to different positions on-demand and selectively functionalized via a photoinitiated, radical-based thiol-ene click reaction. The distribution of different constituent components with desired properties hinges on the independent growth of the individual segment of the bamboo-shaped structure, which can be tailored by using different precursors under specific reaction conditions. Region selectivity of the functionalization is validated by exploiting wetting transitions along bamboo segments, visualized by confocal microscopy.

Solar interfacial evaporation (SIE) has emerged as a highly promising approach for sustainable freshwater harvesting. However, maintaining a stable evaporation rate and achieving a high freshwater yield in high-salinity brines remain a significant challenge. In this study, we present the development of silicone sponge-based evaporators with a "free-salt" structure, designed to enhance the efficiency of SIE and freshwater collection.

Carbon aerogel piezoresistive sensors (CAPSs), owing to their good thermal stability, self-constructed conductive network, and fast response to pressure, have attracted extensive attention in the field of flexible and wearable electronics in recent years. However, it is still a great challenge for CAPSs to monitor subtle deformations and achieve high-performance underwater piezoresistive sensing. Herein, a superhydrophobic and electrically conductive carbon aerogel composite (CAC) was fabricated by the combination of fluorination of carbon aerogels and decoration of fluorinated halloysite nanotubes (HNTs).
