Core Viewpoint - The article discusses the recent advancements in Metal-Organic Frameworks (MOFs) and their application in creating ultra-miniature fluid chips, highlighting their potential to revolutionize computing by mimicking brain-like memory functions [1][20]. Group 1: MOF Technology and Applications - MOFs, once deemed "useless," have gained recognition after winning the Nobel Prize in Chemistry, leading to innovative applications such as fluid chips [1][20]. - The newly developed fluid chips can perform conventional calculations while also retaining previous voltage changes, resembling short-term memory similar to that of brain neurons [2][3]. - The creation of advanced fluid chips using MOF materials addresses the challenges of high-precision nano-channel devices, enabling adjustable non-linear ion transport [4][5]. Group 2: Device Structure and Functionality - Researchers constructed a layered nano-fluid transistor device (h-MOFNT) using Zr-MOF-SO₃H crystals, which features heterogeneous junctions for enhanced performance [7][8]. - The device exhibits non-linear proton transport characteristics, differing from typical diode behavior, indicating a threshold-controlled transport mechanism [12][13]. - The h-MOFNT demonstrated a memory effect, capable of retaining past voltage states, which could lead to applications in liquid-based information storage and brain-like computing [18][19]. Group 3: Historical Context and Future Potential - Historically, MOFs have been viewed as having significant theoretical potential but lacking practical applications, with over 100,000 related papers published but few achieving industrial application [25][26]. - The challenges faced by MOFs include structural stability issues and complex synthesis processes, which have hindered their widespread use [27][28]. - The emergence of MOF-based chips suggests that the material may not be "useless" but rather that suitable applications have yet to be fully explored [29].
