Abstract: A flexible boron nitride nanoribbon aerogel has an interconnected three-dimensional porous network structure which is formed by mutually twining and contacting boron nitride nanoribbons and consists of macropores having a pore diameter of more than 50 nm, mesopores having a pore diameter of 2-50 nm and micropores having a pore diameter of less than 2 nm. The preparation method of the flexible boron nitride nanoribbon aerogel includes the following steps: performing high-temperature dissolution on boric acid and a nitrogen-containing precursor to form a transparent precursor solution, preparing the transparent precursor solution into precursor hydrogel, subsequently drying and performing high-temperature pyrolysis to obtain the flexible boron nitride nanoribbon aerogel. The boron nitride nanoribbon aerogel has excellent flexibility and resilience and can withstand different forms of loads from the outside within a wide temperature range.

Abstract: A stretchable circuit board has stretchability as well as flexibility of the flexible substrate and retains mechanical and electrical properties even under larger deformation such as bending, twisting, etc. The liquid metal pattern can exhibit stretchability almost the same as that of the polymer substrate due to the liquid metal being fully wetted on the substrate with metal patterns based on the wetting behavior of the liquid metal. Therefore, the stretchable circuit board can achieve both mechanical and electrical properties even under physical deformation such as bending, stretching and twisting. It is demonstrated that the stretchable circuit board can be effectively applied to wearable tactile interfaces, stretchable solar cell arrays, stretchable displays, and wearable electronic devices.

Abstract: An improved nanomanipulation system is provided for performing nanomanipulation operations in relation to a sample surface. The system includes: an atomic force microscope having a probe for performing nanomanipulation operations on the sample surface, where the probe includes a cantilever having a layer of piezoelectric material; a position detector configured to ascertain deformation of the cantilever during a nanomanipulation operation; and an adaptable end effector controller adapted to receive data indicative of the deformation from the position detector and implements a control scheme based on the deformation data. The control scheme produces a control signal that is applied to the piezoelectric material of the cantilever, thereby maintaining the straight shape of the cantilever during the nanomanipulation operation.

Abstract: A method is provided for constructing a nanodevice. The method includes: fabricating an electrode on a substrate; forming a nanogap across the electrode; dispersing a plurality of nanoobjects onto the substrate using electrophoresis; and pushing one of the nanoobjects onto the electrode using a tip of an atomic force microscope, such that the nanoobject lies across the nanogap formed in the electrode. In addition, remaining nanoobjects may also be pushed away from the electrode using the atomic force microscope, thereby completing construction of a nanodevice.
