Abstract Melatonin ( N ‐acetyl‐5‐methoxytryptamine) is a naturally occurring small molecule that acts as an important secondary messenger in plant stress responses. However, the mechanism underlying melatonin‐mediated signaling pathway responses has not been established. C‐repeat‐binding factors CBF s )/ Drought response element Binding 1 DREB1s ) encode transcription play roles This study determined endogenous melatonin and transcripts level of At , 2, 3 Arabidopsis leaves were...

Abstract Melatonin is an important secondary messenger in plant innate immunity against the bacterial pathogen Pseudomonas syringe pv. tomato ( Pst ) DC3000 salicylic acid (SA)- and nitric oxide (NO)-dependent pathway. However, metabolic homeostasis melatonin-mediated unknown. In this study, comparative metabolomic analysis found that endogenous levels of both soluble sugars (fructose, glucose, melibose, sucrose, maltose, galatose, tagatofuranose turanose) glycerol were commonly increased...

The applications of phase change materials (PCMs) in some practical circumstances are currently limited due to the constant strong rigidity, poor thermal conductivity, and low photoabsorption property. Therefore, design flexibility-enhanced, highly efficient PCMs is greatly desirable challenging. In this work, novel PCM composites (CPmG-x) with stable forms thermally induced flexibility were successfully prepared by grafting comblike poly(hexadecyl acrylate) polymer (PA16, working substance)...

Covalent organic frameworks (COFs) have been widely used in catalysis, energy storage, environmental protection, and separation. However, they require a long assembly period (∼3 days) complex synthesis conditions; differences water resistance restricted their overall versatility. In this paper, the preparation of COF-DhaTab was optimized, process can be easily performed air. Thus, it is feasible for scale-up near future. The superhydrophobic properties (water contact angle, >150°) created by...

Marangoni actuators that are propelled by surface tension gradients hold significant potential in small-scale swimming robots. Nevertheless, the release of "fuel" for conventional chemical is not easily controllable, and single function also limits application areas. Constructing controllable robots with multifunctions still a huge challenge.

The COF-DhaTab/PAN membrane shows prewetting-induced...

Solar interfacial water evaporation shows great potential to address the global freshwater scarcity. Water being inherently energy intensive, Joule-heating assisted solar for addressing insufficient vapor under natural conditions is an ideal strategy. However, simultaneous optimization of low enthalpy, high photothermal conversion, and excellent steam generation within a single material remain rare achievement. Herein, inspired by biological channel structures, large-area film with...
