Solving the problems with Li-air batteries come as close possible to theoretical limits for energy density in a battery. By weight, this is roughly 10 times higher than conventional lithium-ion and would be sufficient power cars range comparable those gasoline engines. But engineering battery has been challenge. Liu et al. managed overcome remaining challenges: They were able avoid electrode passivation, turn limited solvent stability into an advantage, eliminate fatal caused by superoxides,...
The use of a magic-angle turning and phase-adjusted spinning sideband NMR experiment to resolve quantify the individual local environments in high field 7Li 31P spectra paramagnetic lithium-ion battery materials is demonstrated. short radio frequency pulses provides an excitation bandwidth that sufficient cover shift anisotropy >1 MHz breadth, allowing isotropic anisotropic components be resolved.
Optical force, coming from momentum exchange during light-matter interactions, has been widely utilized to manipulate microscopic objects, though mostly in vacuum or liquids. By contrast, due the light-induced thermal effect, photophoretic force provides an alternative and effective way transport light-absorbing particles ambient gases. However, most cases these forces work independently. Here, by employing synergy of optical we propose experimentally demonstrate a configuration which can...
Silver selenide, Ag2Se, is a promising low-temperature thermoelectric material which can be used to harvest the low-quality waste heat for electrical power generation or cool microelectronics. Currently, investigation on Ag2Se and its derivatives has become hot topic in community, but properties of below 300 K have been rarely investigated. In this study, we prepared by using zone-melting method. The thermal transport zone-melted from 5 380 were systematically investigated compared with...
Li–Fe antisite defects are commonly found in LiFePO4 particles and can impede or block Li diffusion the single-file channels. However, due to their low concentration (∼1%), effect of on has only been systematically investigated by theoretical approaches. In this work, exchange between solid (92.5% enriched with 6Li) liquid electrolyte solution (containing natural abundance Li, 7.6% 6Li 92.4% 7Li) was measured as a function time both ex situ solid-state nuclear magnetic resonance experiments....

Imaging with single-pixel detectors becomes attractive in many applications where pixelated are not available or cannot work. Based on a correlation between the probing patterns and realizations, optical imaging detector offers an indirect way to recover sample. It is well recognized that through dynamic complex scattering media challenging, scaling factors lead serious mismatches realizations. In this paper, we report self-corrected realize high-resolution object reconstruction using...
Mobi-Li-ty: Lithium mobility, as a function of temperature during battery cycling, can be simply monitored by using in situ T2' relaxation measurements. Since Li dynamics are strongly related to structural properties, the changes used detect changes, such ordering.
Optical techniques have boosted a new class of cryptographic systems with some remarkable advantages, and optical encryption not only has spurred practical developments but also brought insight into cryptography. However, this does mean that it is elusive for the opponents to attack systems. In paper, first time our knowledge, we experimentally demonstrate machine-learning attacks on interference-based encryption. Using models are trained by series ciphertext-plaintext pairs, an unauthorized...
In this Letter, we propose high-resolution ghost imaging (GI) through complex scattering media using temporal correction. We provide evidence that the theoretical description about GI based on spatially correlated beams is still incomplete and cannot work in scenarios. complete of correction beam correlations GI. The optical experiments demonstrate images can always be retrieved by rectified temporally corrected correlation algorithm even complex, dynamic, highly strong environments where...
Micro-nanoplastics (MNPs) enter biological systems, forming a protein corona (PC) by adsorbing proteins from bodily fluids, influencing their effects. Mass spectrometry-based proteomics characterizes PC composition, and recent advances have leveraged amino acid sequence-derived features to predict formation using supervised random forest (RF) classifier. However, mass spectrometry often generates substantial missing values (MVs), which may hinder the model's predictive performance...
Optical encryption has attracted wide attention for its remarkable characteristics. Inspired by the development of double random phase encoding, many researchers have developed a number optical systems practical applications. It also been found that computer-generated hologram (CGH) is highly promising encryption, and CGH-based possesses advantages simplicity high feasibility implementations. An input image, i.e., plaintext, can be iteratively or non-iteratively encoded into one several...
Optical encryption has provided a new insight for securing information; however, it is always desirable that high security can be achieved to withstand the attacks. In this Letter, we propose method via learning complex scattering media optical encryption. After recordings through media, designed model trained. The proposed uses an setup with experimentally record ciphertexts and generate keys. During decryption, trained its parameters applied as addition, various parameters, e.g., virtual...
Spectrum can be acquired by Hadamard transform, and the spectrum energy concentrates on upper-left corner according to chosen Walsh-ordering bases. Hence, measurement of main coefficients facilitate reconstruction objects. In this letter, we propose a method for directly calculating each coefficient using only single-step in single-pixel imaging (SPI) high-contrast object reconstruction. The proposed significantly reduce number measurements SPI. addition, an effective noise suppression...
A new cascaded microwave photonic filter that can realize a high Q value is presented. It consists of two infinite impulse response filters based on active loops. Owing to wavelength conversion employing cross-gain modulation the amplified spontaneous emission spectrum semiconductor optical amplifier in one loop, interference between modulated signals different taps from loops be avoided, and stable transmission characteristics then achieved. Using this structure, free spectral range...
