1. IntroductionCyclodextrin is series of cyclic oligosaccharides produced through glucotransferase by Bacillus, with multiple glucopyranose molecules composed of 1,4-glycosidic bonds in a cone-shaped cylindrical structure. The inner cavity of cyclodextrin is hydrophobic, while the outer cavity is hydrophilic. When the quantity of glucopyranose monomers is seven, it is called β-cyclodextrin (BCD), which has the inclusion…

Electric space propulsion systems use energized atoms to generate thrust. The high-speed beams of ions bump against the graphite surfaces of the thruster, eroding them a little more with each hit, and are the systems’ primary lifetime-limiting factor. When ion thrusters are ground tested in an enclosed chamber, the ricocheting particles of carbon from the…

In situ observation and recording of important liquid-phase electrochemical reactions in energy devices is crucial for the advancement of energy science. A research team led by a scholar from City University of Hong Kong (CityU) recently developed a novel, tiny device to hold liquid specimens for transmission electron microscopy (TEM) observation, opening the door to…

Conventional conductive agents added into thermoplastics can’t provide stable, uniform target electrical conductivity and have a negative impact on mechanical properties. This increases the number of out-of-spec parts and forces manufacturers to compromise on final product performance. Thermoplastic compounds enhanced with graphene nanotubes demonstrate permanent, stable conductivity without any variations at the surface and with…

With some careful twisting and stacking, MIT physicists have revealed a new and exotic property in “magic-angle” graphene: superconductivity that can be turned on and off with an electric pulse, much like a light switch. The discovery could lead to ultrafast, energy-efficient superconducting transistors for neuromorphic devices — electronics designed to operate in a way…

Rice University researchers already knew the atoms in perovskites react favorably to light. Now they can see precisely how those atoms move. A breakthrough in visualization supports their efforts to squeeze every possible drop of utility out of perovskite-based materials, including solar cells, a long-standing project that only recently yielded an advance to make the…

The structure of two-dimensional titanium oxide brakes-up at high temperatures by adding barium; instead of regular hexagons, rings of four, seven and ten atoms are created that order aperiodically. A team at Martin Luther University Halle-Wittenberg (MLU) made this discovery in colaboration with researchers from the Max Planck Institute (MPI) for Microstructure Physics, the Université…

Starting with the emergence of quantum mechanics, the world of physics has been divided between classical and quantum physics. Classical physics deals with the motions of objects we typically see every day in the macroscopic world, while quantum physics explains the exotic behaviors of elementary particles in the microscopic world. Many solids or liquids are…

Mobile phone batteries with a lifetime up to three times longer than today’s technology could be a reality thanks to an innovation led by engineers at RMIT University. Rather than disposing of batteries after two or three years, we could have recyclable batteries that last for up to nine years, the team says, by using…

Graphene-based olfactory sensors that can detect odor molecules based on the design of peptide sequences were recently demonstrated by researchers at Tokyo Tech. The findings indicated that graphene field-effect transistors (GFETs) functionalized with designable peptides can be used to develop electronic devices that mimic olfactory receptors and emulate the sense of smell by selectively detecting…

Sixteen years have passed since engineer Martin Eberhard unveiled his futuristic custom-designed sports car before a crowd of investors, journalists, and potential buyers in a Santa Monica Airport hangar. The Roadster, as it was called, contained a lot of innovative engineering, but nothing about it mattered more than the 6,831 lithium-ion battery cells packed into…

The most well-known forms of carbon include graphite and diamond, but there are other more exotic nanoscale allotropes of carbon as well. These include graphene and fullerenes, which are sp2 hybridized carbon with zero (flat-shaped) or positive (sphere-shaped) curvatures. Meanwhile, sp2 hybridized carbon with negative curvature, called “schwarzite,” has been proposed theoretically, and its discovery…

Sometimes friction is good, such as the friction between a road and a car’s tires to prevent the vehicle from skidding. But sometimes friction is bad — if you did not put oil in that very same car, there would be so much friction in the bearings of the engine that the car could not…
