In 1 M KOH and in 0.5 NaCl + KOH, the overpotential of nanoflower-like FeNiCrMnCoOOH/NF is 201 223 mV, respectively, at a current density 10 mA cm −2 .
A new regime in the interaction of a two-color ($\ensuremath{\omega},2\ensuremath{\omega}$) laser with nanometer-scale foil is identified, resulting emission extremely intense, isolated attosecond pulses---even case multicycle lasers. For foils irradiated by lasers exceeding blow-out field strength (i.e., capable fully separating electrons from ion background), addition second harmonic results stabilization up to intensity. This then followed sharp transition transparency that essentially...
Oxygen evolution reaction (OER) is the key anode of electrolytic water. To improve slow OER kinetics, we synthesize nanoflower-like Co-Fe-Cr-Mo-Mn high-entropy spinel (HES) nanosheets on nickel foam (NF) by one-step solvothermal method, which exhibit an overpotential (η
A new scheme of ion acceleration by crossing two ultraintense laser pulses in a near-critical relativistically transparent plasma is proposed. One laser, acting as trigger, preaccelerates background ions its radial direction via the laser-driven shock. Another crossed drives comoving snowplow field which traps some preaccelerated and then efficiently accelerates them to high energies up few giga-electron-volts. The final output beam collimated quasimonoenergetic due momentum-selection...
Abstract The Daqingshan area is located in the Khondalite belt northern margin of North China Craton. It has best-preserved Mesozoic basin and an ideal for research on Jurassic strata. Sandstones mainly contain quartz feldspar, with significantly less debris content. In addition, petrography geochemical classifications have revealed presence arkose wacke. Chondrite-normalized rare earth element patterns samples are characterized by enrichment light elements flat trend toward heavy elements....
We theoretically and numerically demonstrate the generation of a relativistic modified Bessel-Gaussian beam (MBGB) via plasma-based braiding. It is realized by injecting several intense Gaussian pulses with well-designed offsets angles into an underdense plasma channel which acts as laser-pulse combiner refractive coupling. The MBGB propagates stably in well-controlled orbital angular momentum large value, exciting twisted wave. After leaving plasma, it becomes unguided survives vacuum for...
Shot-to-shot electron beam pointing instability in the plasma bubble, defined here as jitter (EBJ), is a long-standing problem that limits potential of laser wakefield accelerator (LWFA) range demanding applications. In general, EBJ caused by variations and parameters from shot to shot, although exact physical mechanism which grows wave remains unclear. this work we theoretically investigate fundamental physics inside bubble show how intrinsic betatron oscillation can act an amplifier...
Nowadays, due to the burning of fossil energy has many negative impacts on environment, people are looking for new sustainable sources that can replace energy, and among them, geothermal solar more prominent, but two alone have certain shortcomings, since complementary systems compensate some shortcomings sources, much research been done in this field. This essay summarizes conclusion from those studies identify shortcomings. The largest losses system always power system. component with...
An accelerating elevator changes the apparent weight of any object inside it from original weight, as measured elevator, because acceleration causes an inertial force on it. For in a running variation object. We have studied time dependence and thus elevator. chosen initial final floors, we by using electronic scale shot readings watch during movement Then analyzed data collected recorded video. If floors are exchanged, variations are, respectively, same magnitudes opposite signs. The...
We propose to effectively realize a time-dependent gravitational acceleration by using running elevator, so that simple pendulum inside it becomes one with acceleration. did such an experiment realistic and analyzed the data. The of elevator is much smaller than acceleration, only when starts stops. However, we have managed establish effect on oscillation pendulum. pronounced if put in container vertically accelerating, time-dependent, while its magnitude comparable
