Carbon fiber aerogel made from raw cotton : a novel, efficient and recyclable sorbent for oils and organic solvents
Twisted carbon fiber (TCF) aerogel with good selective sorption is produced in large scale by using raw cotton as the precursor. TCF aerogel shows highly efficient sorption of organic liquids (pump oil: up to 192 times its ...
Fabrication of flexible, all-reduced graphene oxide non-volatile memory devices
A flexible, all reduced graphene oxide non-volatile memory device, with lightly reduced GO as an active layer and highly reduced GO as both top and bottom electrodes, is fabricated by a full-solution process and its ...
Mechanical exfoliation and characterization of single- and few-layer nanosheets of WSe2, TaS2, and TaSe2
Single- and few-layer transition-metal dichalcogenide nanosheets, such as WSe2, TaS2, and TaSe2, are prepared by mechanical exfoliation. A Raman microscope is employed to characterize the single-layer (1L) to quinary-layer ...
Layer thinning and etching of mechanically exfoliated MoS2 nanosheets by thermal annealing in air
A simple thermal annealing method for layer thinning and etching of mechanically exfoliated MoS2 nanosheets in air is reported. Using this method, single-layer (1L) MoS2 nanosheets are achieved after the thinning of MoS2 ...
Memory devices using a mixture of MoS2 and graphene oxide as the active layer
A mixed film consisting of 2D MoS2 and graphene oxide (GO) nanosheets is used to fabricate memory devices. The conductive MoS2 component in the MoS2-GO film increases the film conductivity, thus facilitating oxygen migration ...
Periodic AuAg-Ag2S heterostructured nanowires
AuAg-Ag2S heterostructured nanowires consisting of periodic AuAg alloy and Ag2S nanocrytals are synthesized in a simple, one-pot reaction. After the AuAg alloy nanowire with a diameter of 2–3 nm is synthesized, it is ...
