The techno-economic performances and life cycle greenhouse gas emissions of conventional NG-based, carbon-capturing, nuclear-powered or renewable ammonia production are evaluated.
The medicinal chemistry and preclinical biology of imidazopyridine-based inhibitors diacylglycerol acyltransferase 2 (DGAT2) is described. A screening hit 1 with low lipophilic efficiency (LipE) was optimized through two key structural modifications: (1) identification the pyrrolidine amide group for a significant LipE improvement, (2) insertion sp(3)-hybridized carbon center in core molecule simultaneous improvement N-glucuronidation metabolic liability off-target pharmacology. candidate 9...
Synthetic natural gas (SNG) is of great interest in reducing fossil energy consumption while maintaining compatibility with existing NG infrastructure and end-use applications equipment. SNG can be produced using clean H2 generated from renewable or nuclear CO2 captured stationary sources the atmosphere. In this study, we develop an engineering process model production Aspen Plus® scales reported by industry. We examine levelized cost life cycle greenhouse (GHG) emissions under various...
For the commercialization of anion exchange membrane fuel cells (AEMFCs), (AEM), which is a key component AEMFCs, requires not only excellent ion conductivity but also high alkaline stability. Therefore, in this study, hybrid composed quaternized poly(phenylene oxide) (QPPO) with dense sites and polyvinyl alcohol (PVA), known for its superior chemical mechanical properties, prepared. The QPPOx-PVAy AEMs (where x y represent weight ratio QPPO PVA) forms hydrogen bonds or electrostatic...
Efforts to achieve economy-wide decarbonization require the dramatic reduction and eventual elimination of emissions from industrial sector, which steel ammonia production contribute significantly. Low-carbon hydrogen can play a key role in decarbonizing both commodities. This study provides techno-economic life-cycle analysis different routes for steelmaking via direct reduced iron--electric arc furnace synthesis five locations with estimated technological progress through 2035. We model...
The scaling of semiconductor device below 10nm has faced the higher process difficulty and longer development periods. Three-dimensional integrated circuits (3D IC) using chip partitioning wafer-to-wafer bonding have been acknowledged as next generation stacking technology because smaller form factor, density integration performance compared to same-node devices. Wafer-to-wafer is widely used in stacked CMOS image sensor, that is, between pixel logic wafer, this potential apply other Cu-Cu...
Transparent double-layer heaters that consist of aluminum-doped zinc oxide and fluorine-doped tin films are prepared by electron cyclotron resonance-metal organic chemical vapor deposition RF-sputtering systems, in sequence. The double-layered transparent conducting film is designed to achieve both high conductivity high-temperature performance. This structure has lower sheet resistance, due the grain size increase with respect single-layer films. oxide/aluminum-doped shows a resistance as...
3D Multi-stacking technology using Cu-Cu hybrid wafer bonding has been developed to achieve superior power, speed performances and higher density with minimized form factor. To realize multi-stacked device by Wafer on (WoW) bonding, both Face-to-Face (F2F) Back-to-Face (B2F) interconnection can be required for more efficient simple I/O pad design as well lower resistance thanks shorter interconnections. In this paper, we successfully demonstrated wafer-level multi-stacking structure applying...
Techno-ecologically synergistic designs of the food–energy–water-waste nexus can be better than conventional techno-centric while meeting ecological and societal needs.
Inhibition of triacylglycerol (TAG) biosynthetic enzymes has been suggested as a promising strategy to treat insulin resistance, diabetes, dyslipidemia, and hepatic steatosis. Monoacylglycerol acyltransferase 3 (MGAT3) is an integral membrane enzyme that catalyzes the acylation both monoacylglycerol (MAG) diacylglycerol (DAG) generate DAG TAG, respectively. Herein, we report discovery characterization first selective small molecule inhibitors MGAT3. Isoindoline-5-sulfonamide (6f,...
We have successfully developed two kinds of novel 3-layer stacked backside-illuminated (BSI) voltage-domain global shutter (GS) CMOS image sensors (CIS) with consecutive void-free hybrid bonding processes. A new GS CIS contains the separate high-capacity capacitors on middle wafer which are connected to pixel transistors via pixel-pitch Cu-to-Cu bonding, followed by another that connects capacitor bottom logic wafer. Another type sensor architecture thinned Si layer in enables 3-dimensional...
In the Calvin cycle of photosynthesis, ribulose-1,5-bisphosphate carboxylase/oxygenase (RubisCO) catalyzes conversion ribulose 1,5-bisphosphate to 3-phosphoglyceric acid (3-PGA) while incorporating atmospheric CO2 into an organic molecule. Thus, RubisCO is nature's CO2-sequestering enzyme that present in chloroplasts. As effort mitigate climate change, biomimetic carbon fixation technologies have been developed through immobilization nanostructures form nanostructure–RubisCO complexes. The...
The environmental impact of an engineered system depends on factors such as economic policies, efficiency the technology, and extent to which it is used in society. Methods for making decisions toward sustainability certainly account technological aspects efficiency, but have been lacking accounting broader implications effect markets human behavior. These shortcomings can result perverse outcomes: improvement may increase by encouraging greater consumption. Recent advances assessment...
