We report a method using in situ etching to decouple the axial from the radial nanowire growth pathway,independent of other growth *** a wide range of growth parameters can be explored to improve the nanowire properties without concern of tapering or excess structural defects formed during radial *** demonstrate the method using etching by hCl during InP nanowire *** improved crystal quality of etched nanowires is indicated by strongly enhanced photoluminescence as compared to reference nanowires obtained without etching.

Neurodegenerative diseases are a heterogeneous group of maladies, characterized by progressive loss of neurons. these diseases involve an intricate pattern of cross-talk between different types of cells to maintain specific signaling pathways. A component of such intercellular cross-talk is the exchange of various types of extracellular vesicles (EVs). Exosomes are a subset of EVs, which are increasingly being known for the role they play in the pathogenesis and progression of neurodegenerative diseases, e.g., synucleinopathies and tauopathies. the ability of the central nervous system exosomes to cross the blood-brain barrier into blood has generated enthusiasm in their study as potential biomarkers. however, the lack of standardized, efficient, and ultra-sensitive methods for the isolation and detection of brain-derived exosomes has hampered the development of effective biomarkers. Exosomes mirror heterogeneous biological changes that occur during the progression of these incurable illnesses, potentially offering a more comprehensive outlook of neurodegenerative disease diagnosis, progression and treatment. In this review, we aim to discuss the challenges and opportunities of peripheral biofluid-based brain-exosomes in the diagnosis and biomarker discovery of Alzheimer’s and Parkinson’s diseases. In the later part, we discuss the traditional and emerging methods used for the isolation of exosomes and compare their advantages and disadvantages in clinical settings.

high-spin states in the odd-odd Re have been investigated via the Sm(Al,4n)Re reaction through excitation functions, x-γand γ-γcoincidence measurements. A level scheme consisting of three rotational bands have been identified for the first time extending the high-spin studies of A～160 odd-odd nuclei to the currently lightest rhenium isotope. the three bands have

A multichannel calorimeter system is designed and constructed which is capable of delivering single-shot and broadband spectral measurement of terahertz(thz) radiation generated in intense laser–plasma interactions. the generation mechanism of backward thz radiation(BtR) is studied by using the multichannel calorimeter system in an intense picosecond laser–solid interaction experiment. the dependence of the BtR energy and spectrum on laser energy, target thickness and pre-plasma scale length is obtained. these results indicate that coherent transition radiation is responsible for the low-frequency component(thz) of BtR. It is also observed that a large-scale pre-plasma primarily enhances the high-frequency component(>3 thz) of BtR.

the diffusion coefficient of carbon in surface layer of steel-20 rare earth carburixed at 880 degreesC and 900 degreesC for 8 h was calculated by substituting the measured layer depths into the diffusion equation. the mathematical model of the transfer coefficient of carbon was deduced based on the kinetics of weight gain during gas carburizing. the calculated results show that the main reason why the gas carburizing process is accelerated is due to the obvious increase in the diffusion coefficient and transfer coefficient of carbon resulted from the addition of RE.
