Heteroatom-doped carbon has been widely investigated as anode materials for sodium-ion batteries (SIBs). However, simplifying the preparation process and precisely controlling their microstructure to achieve excellent Na storage performance remain significant challenges. Therefore, in this study, high-performance N, P co-doped Na storage carbon anode electrode materials were prepared by one-step carbonization using N, P-rich Eichhornia crassipes (EC) as raw materials and systematically tested for their Na storage performance.

Methods: This was a serial cross-sectional analysis of neonatal hospitalizations of ≥35 weeks' gestational age with International Classification of Diseases diagnostic codes for DS within the National Inpatient Sample. International Classification of Diseases procedure codes were used to identify those who had GT.
Adsorptive desulfurization (ADS) using activated carbon (AC) as adsorbent presents competitive potential in separating thiophenic sulfur from liquid fuels with high selectivity under mild operation conditions. It is also a highly economic remedy in ultra-low sulfur content situations. Most importantly, a suitable feedstock for macroscopic quantity preparation of AC adsorbents with good adsorptive desulfurization performance and low-cost is required to satisfy the requirements of this field.

Currently, to our knowledge, there is no effective pharmacologic prophylaxis for individuals at risk.
Objective: To evaluate the efficacy of hydroxychloroquine to prevent transmission of SARS-CoV-2 in hospital-based HCWs with exposure to patients with COVID-19 using a pre-exposure prophylaxis strategy.
