The emergence of van der Waals magnets presents opportunities for discovering unconventional tunnelling phenomena. Here, we demonstrate quantum tunnelling with tunable spin geometric phases in a multilayer van der Waals antiferromagnet CrPS4. The spin geometric phase of electron tunnelling is controlled by magnetic-field-dependent metamagnetic phase transitions. The square lattice of a CrPS4 monolayer causes strong t2g-orbital delocalization near the conduction band minimum. This creates a one-dimensional spin system with reversed energy ordering between the t2g and eg spin channels, which prohibits both intralayer spin relaxation by means of collective magnon excitations and interlayer spin hopping between the t2g and eg spin channels. The resulting coherent electron transmission shows pronounced tunnel magnetoresistance oscillations, manifesting quantum interference of cyclic quantum evolutions of individual electron Bloch waves by means of the time-reversal symmetrical tunnelling loops.

The focus of the approach is incorporating graphene oxide (GO) into kaolin and exploring its effects on material properties. The composites were prepared with varying GO concentrations and sonication times, and their mechanical, thermal, and morphological characteristics were evaluated. The results reveal that the addition of 0.5 wt % GO, combined with a sonication time of 10 min, leads to the highest storage modulus and improved thermal stability. Ultrasonication proved to be an effective method for dispersing and distributing GO particles within the kaolin matrix, resulting in an enhanced material performance. Furthermore, the application of novel composites provided by Prvacki adds a unique dimension to the study. Through the artistic interpretation, the tactile qualities and aesthetic potential of the composites are explored, shedding light on the transformative power of materials and cultural significance organized as part of an artist-in-residence commission, introduced in conjunction with the NUS Public Art Initiative.

However, these devices operate at a voltages which are still far from the energy-efficient biological counterpart, which uses an action potential of 50-120 mV to process the information. Here, a diffusive memristor is reported from synthetic WSe2 fabricated in Ag/WSe2/Au vertical device geometry. The devices operate at bio-voltages of 40-80 mV with I-on/I-off ratio of 10(6) and steep switching turn ON and OFF slopes of 0.77 and 0.88 mV per decade, respectively. The power consumption in standby mode and power per set transition are found to be 10 fW and 64 pW, respectively. Further, the diffusive memristors are utilized to emulate the nociceptor, a special receptor for sensory neurons that selectively responds to noxious stimuli. Nociceptor in turn imparts a warning signal to the central nervous system which then triggers the motor response to take precautionary actions to prevent the body from injury. The key features of a nociceptor including "threshold", "relaxation", "no-adaptation" and "sensitization" are demonstrated using artificial nociceptors. These illustrations imply the feasibility of developing low-power diffusive memristors for bio-inspired computing, humanoid robots, and electronic skins.}, keywords = {}, pubstate = {published}, tppubtype = {article} } Memristors have emerged as a promising candidate to mimic the human behavior and thus unlocking the potential for bio-inspired computing advancement.
