Thermal energy storage system with steam generation system including flow control and energy cogeneration
An energy storage system converts variable renewable electricity (VRE) to continuous heat at over 1000° C. Intermittent electrical energy heats a solid medium. Heat from the solid medium is delivered continuously on demand. An array of bricks incorporating internal radiation cavities is directly heated by thermal radiation. The cavities facilitate rapid, uniform heating via reradiation. Heat delivery via flowing gas establishes a thermocline which maintains high outlet temperature throughout discharge. Gas flows through structured pathways within the array, delivering heat which may be used for processes including calcination, hydrogen electrolysis, steam generation, and thermal power generation and cogeneration. Groups of thermal storage arrays may be controlled and operated at high temperatures without thermal runaway via deep-discharge sequencing. Forecast-based control enables continuous, year-round heat supply using current and advance information of weather and VRE availability. High-voltage DC power conversion and distribution circuitry improves the efficiency of VRE power transfer into the system. |

HCV protease inhibitors
Hepatitis C virus (HCV) is a human pathogen with high morbidity. The HCV NS3/4A protease is essential for viral replication and is one of top three drug targets. A number of drugs have been developed but drug resistant mutant strains emerged. Here we screened and synthesized of novel class of small molecules of Formula I or Formula IA based on tryptophan derivative scaffold as HCV NS3/4A protease inhibitors that is active against both wild type and mutant form of the protease. Only the docking hits with a binding pose that is not affected by the most frequent mutations in the active site were selected for experimental validation. The antiviral activities were evaluated by replicon and enzymatic assays. Twenty-two compounds in this series were found to inhibit HCV with EC50 values ranging between 0.64 to 63 μM with compound 22 being the most active of this series. In protease assays, 22 had a comparable inhibition profile for the common mutant HCV GT1b D168A and the wild type enzyme. However, in the same assay, potency of the approved drug, Simeprevir, decreased 5.7-fold for the mutant enzyme relative to the wild-type. The top three inhibitors were also tested against four human serine proteases and were shown to be specific to the viral protease. The fluorescent based cell viability assay demonstrated a sufficient therapeutic range for the top three candidates. |
