The relationship between Al/CuO/NC composites and AP is interaction. © 2020 IOP Publishing Ltd.We develop nano-bridged nanosphere lithography (NB-NSL), a modification to the widely used conventional nanosphere lithography (NSL). Nano-bridges between the polystyrene (PS) spheres of a pristine NSL template are controllably formed in a two-step process (i) spin-coating of a dilute styrene solution on top of the template followed by (ii) oxygen plasma etching of the template. We show that the nanobridge dimensions can be precisely tuned by controlling the pre-processing conditions and the plasma etching time. GPNA The resulting lithography templates feature control over the shape and size of the apertures, which determine the morphology of the final nano-island arrays after material deposition and template removal. The unique advantage of NB-NSL is, that PS particle templates based on a single PS particle diameter can be utilized for the fabrication of a variation of nano-island shapes and sizes, whereas conventional NSL yields only bow-tie shaped nano-island with their size being predetermined by the PS particle diameter of the template. © 2020 IOP Publishing Ltd.Despite the huge studies of vacuum devices, nanoscale technologies open new paradigms. The vacuum nanodevices bring multiple advantages, like air instead vacuum for nanometric gap, strong non-linear characteristics and MOS co-integration facility. Therefore, this paper presents the manufacturing process and measured characteristics of a nano-device that uses sub-36 nm gap between two Cr/Au nano-wires. In this way, the metal nano-wires replace the semiconductor nano-islands, while an air gap stands for the "Nothing" region of a first time fabricated variant for a Nothing On Insulator device. The electron-beam lithography mask-less technology is pushed to its technical limit to define a minimum 18 nm wide gap between two Cr/Au nanowires. The main current-voltage curves are measured for this first real device called Nothing On Insulator in the variant Metal-Air-Metal, indicating 10 nA at 10 V, as the optimal variant. The main connections between measurements and technology are emphasized. © 2020 IOP Publishing Ltd.OBJECTIVE Implicit motor learning, which is a non-conscious form of learning characterized by motor performance improvement with practice, plays an essential role in various daily activities. Earlier study using neurofeedback training (NFT), a type of brain-computer interaction that enables the user to learn self-regulating his/her own brain activity, demonstrated that down-regulating alpha over primary motor cortex by NFT could immediately facilitate the implicit motor learning in a relatively simple motor task. However, detailed effects on EEG and implicit motor learning due to NFT especially in a more complex motor task are still unclear. APPROACH We designed a single-blind sham-controlled between-subject study to examine whether alpha down-regulation NFT could facilitate implicit motor learning and also its consolidation in a more difficult and motor predominant task. At left primary motor cortex (C3) in two days, the alpha NFT group received alpha down-regulation training through auditory feedback while ng and alpha change induced by NFT. © 2020 IOP Publishing Ltd.New bulk glass-forming alloy compositions, exceeding a critical casting thickness of 1 mm, are developed in the (quasi-ternary) Ti(Zr)-Ni(Cu)-S system. The ternary eutectic composition Ti65.5Ni22.5Cu12 is stepwise modified through additions of S (0 - 8 at%) and Zr (0 - 22.5 at%) at the expense of Ni and Ti, respectively. By increasing the plate thickness of the casted samples from 500 µm to 1.25 mm, the primary precipitating phases are identified which is for the best glass-formers (e.g. Ti58Zr7.5Ni18.5Cu12S4) an icosahedral phase. In calorimetric experiments, several exothermic crystallization events are observed upon heating glassy samples. The first exothermic event, obscuring the glass transition, is attributed to the formation of the icosahedral phase. As the icosahedral phase forms upon heating and cooling for the best glass-formers, the origin of the increased glass-forming ability might be attributed to a pronounced icosahedral short-range order in the liquid state, impeding the formation of the stable crystalline phases. © 2020 IOP Publishing Ltd.In the article, we report the photoluminescence (PL) properties of D and S defects induced by Si+/Ni+ ions co-implanting into the top Si film of the silicon-on-insulator (SOI) wafer. Variable-temperature PL spectra of these co-implanted SOI samples indicate that the light emitting from the D defects can be observed as high as 273 K. In compared with the other ion-implantation, the Si+/Ni+ ion-co-implantation optimizes luminescent temperature stability of the both D and S defects, and purifies the S defect type in silicon then effectively restrain the spectral broadening of the S-line in PL spectra. The depth distribution of the D and S defects along the normal direction of SOI surface at the corresponding ion-implantation energy has been well depicted by detecting the PL signals of the layer-by-layer etched SOI surface, respectively. These results provide valuable information to fabricate the SOI-based infrared light sources for optical fiber communication. © 2020 IOP Publishing Ltd.Aging is associated with a distal-to-proximal shift in joint kinetics during walking. This plasticity of gait is amplified rather than attenuated in old adults with high physical capacity. Because running is associated with greater kinetic demands at the ankle, older individuals with more versus less lifetime running exposure may retain a larger proportion of their ankle kinetics. The purpose of the study was to compare lower-extremity joint kinetics during walking between middle-aged runners with high and low lifetime running exposure. Eighteen middle-aged runners (9 per group) participated. Joint kinetics were calculated from kinematic and ground reaction force data during overground walking at 1.3 m·s-1 and compared between groups. High exposure runners produced 50% greater positive hip work (P = .03; Cohen d = 1.02) during walking compared with low exposure runners, but ankle kinetics were not different between groups. No other differences in joint kinetics or kinematics were observed between groups. These findings suggest that the age-related increase in hip joint kinetics during walking could be a compensatory gait strategy that is not attenuated by lifetime running exposure alone.
