Thermally Induced Bending of ReS₂ Nanowalls

Abstract

Among the variety of stimuli-responsive materials, temperature-responsive materials (TRMs) can adapt to the surrounding environment in the presence of a thermal stimulus, and they have attracted considerable attention in sensors, actuators, and surface engineering. However, polymers, as the most representative TRMs, are far from ideal with respect to long-term reliability and durability. Here, for the first time, an inorganic material, ReS , is analyzed, which possesses an unexpected temperature-responsive behavior that is triggered by stable and reversible thermally induced bending (TIB). Due to thermal fluctuations in the ReS layers, intrinsic ripples tend to aggravate rapidly with rising temperature. Then, the weak interlayer interaction of ReS is further weakened, thus resulting in interlayer sliding. Due to a decrease in bending rigidity with increasing temperature, out-of-plane bending spontaneously occurs in the ReS layers. Interestingly, this TIB of ReS can recover to its initial configuration when the temperature drops, which is further confirmed by the reversible wetting measurement. Above all, the TIB behavior of ReS exhibits great potential in smart applications, such as smart windows and microfluidic devices, and fills the significant gaps of inorganic TRMs.

Nitrogen-doping induces tunable magnetism in ReS2

“…1f, the interlayer distance was measured to be 0.62 nm, corresponding to the (001) plane of ReS 2 . [19][20][21] X-ray photoelectron spectroscopy (XPS) was utilized to examine the elemental compositions and bonding configurations. To evidence the existence of N, commercial ReS 2 powder was also characterized as a comparison object.…”

The binding energy and dynamics of charge-transfer states in organic photovoltaics with low driving force for charge separation

“…6,[8][9][10][11][12][13][14] The most efficient singlejunction OPV to date has reached a power conversion efficiency of 14% using the NFA ITIC-4F. 15 Despite this rapid rise in efficiency, a fundamental understanding of the charge generation mechanism is still lagging behind.…”

High-efficiency and stable photocatalytic hydrogen evolution of rhenium sulfide co-catalyst on Zn0.3Cd0.7S

“…18,19 Recently, it is confirmed that a new type of TMD, rhenium disulfide (ReS 2 ), has extraordinary photocatalytic properties due to its remarkable electron-hole separation and is a promising photocatalyst for hydrogen production. [20][21][22][23][24] With this in mind, we expect ReS 2 to act as a cocatalyst to further enhance the photocatalytic performance, which may provide new opportunities for photocatalytic H 2 evolution. [25][26][27][28][29][30][31] However, to the best of our knowledge, it has rarely been reported as a cocatalyst for photocatalytic hydrogen production.…”
