Design of a Memristor-Based Digital to Analog Converter (DAC)
Electronics (Switzerland), 2021 A memristor element has been highlighted in recent years and has been applied to several applications. In this work, a memristor-based digital to analog converter (DAC) was proposed due to the fact that a memristor has low area, low power, and a low ...

The Open DAC 2023 Dataset and Challenges for Sorbent Discovery in Direct Air Capture [PDF]
ACS Central Science, 2023 Direct air capture (DAC) of CO2 with porous adsorbents such as metal−organic frameworks (MOFs) has the potential to aid large-scale decarbonization. Previous screening of MOFs for DAC relied on empirical force fields and ignored adsorbed H2O and MOF ...
