Cell Biology International > 47 > 3 > 648 - 659

In this study, methionine sulfoxide (MetO) was identified as an active metabolite that suppresses adipogenesis after screening obese individuals versus the normal population. MetO suppressed the gene and protein expression of CCAAT/enhancer binding protein (C/EBP) α, adipocyte fatty acid binding protein 4 (FABP4), and the nuclear receptor peroxisome proliferator‐activated receptor γ (PPARγ) during...

(Un)conditional collection policies on used products with strategic customers

Chang Dong, Yong Lei, Qian Liu

Production and Operations Management > 32 > 1 > 82 - 97

For generation products characterized by frequent releases of new versions, when a new version is introduced to the market, the current version usually still has a remaining useful life. This creates a challenge for a firm to manage used product collection and upgraded product introductions at the same time, especially with the presence of a secondary market. This paper develops an analytical model...

In sodium–air batteries (SABs), achieving the regulation of the electron transfer number during oxygen reduction reactions (ORRs) in the same electrolyte system remains a significant challenge. In this work, a promising strategy is proposed to dynamically modulate 2e⁻/4e⁻ transfer in ORRs by regulating the electrolyte structures to realize the different performances of SABs. The 4e⁻ ORR can be realized...

Managing return policies with consumer resale

Yong Lei, Qian Liu, Stephen Shum

Naval Research Logistics (NRL) > 69 > 2 > 241 - 256

We consider a retailer selling products to consumers with uncertain valuations under a return policy. After purchases, consumers who find the products undesirable can either return them to the retailer, or resell them on their own. Both the retailer and consumers incur transaction costs in resale. Consumers decide whether to purchase the new products or wait for the resold ones. We investigate how...

Efficient Organic Solar Cells Enabled by Simple Non‐Fused Electron Donors with Low Synthetic Complexity

Yueyue Gao, Minghuan Cui, Shengchun Qu, Huaping Zhao, more

Small > 18 > 3 > n/a - n/a

Fused‐ring electron donors boost the efficiency of organic solar cells (OSCs), but they suffer from high cost and low yield for their large synthetic complexity (SC > 30%). Herein, the authors develop a series of simple non‐fused‐ring electron donors, PF1 and PF2, which alternately consist of furan‐3‐carboxylate and 2,2′‐bithiophene. Note that PF1 and PF2 present very small SC of 9.7% for their...
