The facile diffusion of Li+ ions through the solid electrolyte interphase (SEI) is crucial to realize extremely fast-charging (XFC) batteries. Graphite a promising candidate for electric vehicles and other battery applications. However, it exhibits poor delithiation capacity due exfoliation under high current rates. Therefore, herein, composite polymer binder, named BIAN-LiPAA, with intrinsic ions, was prepared achieve fast charging better ion diffusion. remarkably low-lying energy level...
Abstract The GRAPES-3 experiment located in Ooty, India, samples the electron and muon components extensive air showers using an array of plastic scintillator detectors a telescope (G3MT) consisting proportional counters to study composition primary cosmic rays (PCRs) as well γ -ray sources TeV–PeV energy range. G3MT is designed with appropriate mass absorber shield electromagnetic hadronic shower detect muons above 1 GeV×sec( θ ) energy, incident from zenith angle . We developed simulation...
To protect human rights, holding people accountable and demanding compensation from countries is necessary. International criminal law tools, such as the Nuremberg Verdict of Military Tribunal (IMT) Charter, several rights outlined in Universal Declaration Human Rights. The 1949 Geneva Conventions expanded scope universality principle to include war crimes, protected by numerous covenants are line with specific serious violations. essentially a supplement acting means enforcement determine...
An experimental study on the radiography of various metallic and biological plant samples with a minimum resolution $\ensuremath{\sim}75\text{ }\text{ }\ensuremath{\mu}\mathrm{m}$ using relativistic electron beams from laser plasma accelerator is presented. Electron were generated interaction Ti:sapphire pulses 120 fs duration underdense 4 mm length, created Ar He gas jets, two different parameters, i.e., maximum energy $\ensuremath{\sim}50\text{ }\mathrm{MeV}$ (broad spectrum)...
Abstract With a high theoretical gravimetric capacity of 3579 mAhg −1 , silicon (Si) has made promising claim as an alternative to graphite (372 ) in lithium‐ion battery (LIB) anodes active material. Unfortunately, inherent failure mechanisms (pulverization, delamination, promoting thick interphase formation, and non‐conducting nature) Si have plagued their way toward commercialization. To stabilize anodes, this work reports the design, synthesis, application conducting/crosslinked...
An experimental study of laser driven electron acceleration in N2 and N2-He mixed gas-jet target using pulses duration ~60-70 fs is presented. Generation relativistic beam with quasi-thermal spectra was observed at a threshold density ~1.6x1018 cm-3 case pure N2, the found to increase increasing doping concentration He. At an optimum fraction 50% He generation quasi-monoenergetic beams comparatively higher ~2x1018 cm-3, average peak energy ~168 MeV, spread ~21%, total charge ~220 pC....
We report x-ray emission caused by betatron motion of electrons in a laser wakefield accelerator driven high intensity ($\ensuremath{\sim}4\ifmmode\times\else\texttimes\fi{}{10}^{19}\text{ }\text{ }\mathrm{W}/{\mathrm{cm}}^{2}$) pulse interaction with 4-mm long helium gas-jet and study the role collective oscillation as well plasma density. The oscillations electrons, inferred from observed wavy pattern electron beam spectrum (up to 300 MeV) led enhance peak flux which was found be further...
The design and development of a magnetic spectrograph covering broad electron energy range (few MeV to 1 GeV) for laser plasma accelerators are presented. Two phosphor screens, one in the forward other side direction, were used record electrons spectra after dispersion from magnet. third screen was kept front magnet simultaneously beam profile. GEANT4 simulations performed estimate extra divergence introduced by In setup, transported through Ti foil thickness 54 μm vacuum chamber, therefore,...
We demonstrate high brightness betatron x-ray generation from a chirped laser pulses driven plasma accelerator. It is shown that positively pulse leads to the initiation and enhancement of collective oscillations electrons inside bubbles, due associated front tilt (PFT). The PFT causes transverse drift bubbles with respect axis, which results in generation. At an optimum chirp, enhanced emission >108 photons/pulse/sr 0.1% BW critical energy ∼18 keV was observed by factor >2...
