Core Viewpoint - The article highlights the recent breakthrough in using Metal-Organic Frameworks (MOFs) to create ultra-miniature fluid chips, which can perform computations and exhibit short-term memory similar to brain neurons, challenging the previous notion that MOFs were "useless" [1][20]. Group 1: MOF Technology and Applications - MOFs, once considered theoretical with limited practical applications, have now been recognized for their potential in advanced computing technologies following their Nobel Prize acknowledgment [1][21]. - The newly developed fluid chip, made from MOF materials, can overcome limitations of traditional electronic chips by enabling advanced functionalities [3][5]. - The h-MOFNT device constructed from layered Zr-MOF-SO₃H crystals demonstrates unique ion transport properties, allowing for precise control over ionic movement [7][12]. Group 2: Device Characteristics and Performance - The h-MOFNT device exhibits non-linear proton transport characteristics, which differ from typical diode behavior, indicating a threshold-controlled transport mechanism [12][13]. - Experimental results show that the device can remember past voltage states, demonstrating fluid memory and learning capabilities, akin to electronic devices [16][18]. - The ability to create a small fluid circuit using multiple h-MOFNTs showcases the potential for complex computations and memory functions in liquid systems [16][19]. Group 3: Historical Context and Future Prospects - Historically, despite extensive research (over 100,000 related papers), the practical industrial application of MOFs has been limited due to issues like structural stability and production costs [25][27]. - The emergence of MOF-based chips suggests that the material may not be "useless," but rather that suitable applications were not previously identified [29]. - Future developments may lead to the realization of liquid-based information storage and brain-like computing systems through innovative design of heterogeneous constraint systems [19].
