“…This feature is more like the closing of a stapler; thus the observed magnetic dipole band was named as "stapler band". For the stapler band in 115 In, the electric rotation of a nearly oblate core was found to play a more dominant role than the magnetic rotation [16], whereas for the one in 75 As, the valence nucleons in highj orbitals rather than the core are responsible for the closing of the stapler of angular momentum [17].…”

“…The magnetic rotation and electric rotation represent two extreme cases that can be well distinguished. Recently an angular momentum generating mechanism called "stapler" mechanism, which is a variant of the shears mechanism, was proposed for 115 In [16] and 75 As [17] based on the angular momentum analyses by the tilted axis cranking covariant density functional theory (TAC-CDFT) [14]. In the stapler mechanism, only the neutron (proton) angular momentum moves obviously toward the direction of the total angular momentum while the proton (neutron) angular momentum is almost motionless.…”

“…So far, only four stapler bands have been suggested, in 57 Mn [18], 75 As [17], 115 In [16], and 144 Tb [19]. It is worthwhile to explore more examples of stapler bands in different mass regions and to better understand the interplay between the magnetic rotation and electric rotation.…”

ABSTRACT. The efficiency of offshore oil spill response not only relies on an efficaciously global decision/planning in devices combination and allocation, but also depends on the timely control for response devices (e.g., skimmers and booms). However, few studies have reported on such decision framework with a timely integration of global planning and operation control to support offshore oil spill response. This study developed an agent-based simulation-optimization approach to provide sound decisions for device combination and allocation during offshore oil spill recovery in a fast, dynamic and cost-efficient manner under uncertain conditions. Meanwhile, the proposed approach aimed at providing operation control schemes for different devices, reflecting the site conditions, and correspondingly adjusting the global planning in a real-time manner. Such functions would be extremely helpful in the harsh environments prevailing in offshore Newfoundland. In the case study, the developed approach was applied to determine the allocation of 3 responding vessels in collecting spilled oil at 7 locations. The routes of the responding vessels for response operation were optimized and reflected by the principle agent-based programming. Furthermore, several oil weathering processes (e.g., evaporation and dispersion) were also taken into account in the optimization. The modeling results indicated that a minimal timeframe of 21 hours was needed for vessel allocation and recovery operation, leading to an oil recovery rate of 90%. By taking evaporation and dispersion into account, the optimal time window was 18 hours, leading to an oil recovery rate of 75%, an evaporation rate of 12%, and a dispersion rate of 3%. The proposed approach can timely and effectively support the optimal allocation of devices, the control of operation, and the real-time adjustment of global decision making for oil recovery under dynamic conditions.

Biomass to Aromatic Amine Module: Alkali Catalytic Conversion of N‐Acetylglucosamine into Unsubstituted 3‐Acetamidofuran by Retro‐Aldol Condensation

Aminofurans are widely used in drug synthesis as aromatic modules analogous to aniline. However, unsubstituted aminofuran compounds are difficult to prepare. In this study, a process for the selective conversion of N‐acetyl‐d‐glucosamine (NAG) into unsubstituted 3‐acetamidofuran (3AF) is developed. The yield of 3AF from NAG catalyzed by a ternary Ba(OH)2−H3BO3−NaCl catalytic system in N‐methylpyrrolidone at 180 °C for 20 min can reach 73.9 %. Mechanistic studies reveal that the pathway to 3AF starts with a base‐promoted retro‐aldol condensation of the ring‐opened NAG, affording the key intermediate N‐acetylerythrosamine. Judicious selection of the catalyst system and conditions enables the selective conversion of biomass‐derived NAG into 3AF or 3‐acetamido‐5‐acetylfuran.
