DataSheet_1_Physicochemical properties and molecular mechanisms of different resistant starch subtypes in rice.docx
Resistant starch (RS) can help prevent diabetes and decrease calorie intake and that from plants are the main source of mankind consumption. Rice is many people’s staple food and that with higher RS will help health management. A significantly positive correlation exists between apparent amylose content (AAC) of rice and its RS content. In this study, 72 accessions with moderate or high AAC were selected to explore the regulatory mechanisms and physicochemical properties on different proceeding types of rice RS. RS in raw milled rice (RSm), hot cooked rice (RSc), and retrogradation rice (RSr) showed a wide variation and distinct controlling mechanisms. They were co-regulated by Waxy (Wx), soluble starch synthase (SS) IIb and SSI. Besides that, RSm was also regulated by SSIIa and SSIVb, RSc by granule-bound starch synthase (GBSS) II and RSr by GBSSII and Pullulanase (PUL). Moreover, Wx had significant interactions with SSIIa, SSI, SSIIb and SSIVb on RSm, but only the dominant interactions with SSIIb and SSI on RSc and RSr. Wx was the key factor for the formation of RS, especially the RSc and RSr. The genes had the highest expression at 17 days after flowering and were beneficial for RS formation. The longer the chain length of starch, the higher the RS3 content. RSc and RSr were likely to be contained in medium-size starch granules. The findings favor understanding the biosynthesis of different subtypes of RS.</p

Controllable Regulation of the Oxygen Redox Process in Lithium–Oxygen Batteries by High-Configuration-Entropy Spinel with an Asymmetric Octahedral Structure
Designing bifunctional electrocatalysts to boost oxygen
redox reactions
is critical for high-performance lithium–oxygen batteries (LOBs).
In this work, high-entropy spinel (Co0.2Mn0.2Ni0.2Fe0.2Cr0.2)3O4 (HEOS) is fabricated by modulating the internal configuration
entropy of spinel and studied as the oxygen electrode catalyst in
LOBs. Under the high-entropy atomic environment, the Co–O octahedron
in spinel undergoes asymmetric deformation, and the reconfiguration
of the electron structure around the Co sites leads to the upward
shift of the d-orbital centers of the Co sites toward the Fermi level,
which is conducive to the strong adsorption of redox intermediate
LiO2 on the surface of the HEOS, ultimately forming a layer
of a highly dispersed Li2O2 thin film. Thin-film
Li2O2 is beneficial for ion diffusion and electron
transfer at the electrode–electrolyte interface, which makes
the product easy to decompose during the charge process, ultimately
accelerating the kinetics of oxygen redox reactions in LOBs. Based
on the above advantages, HEOS-based LOBs deliver high discharge/charge
capacity (12.61/11.72 mAh cm–2) and excellent cyclability
(424 cycles). This work broadens the way for the design of cathode
catalysts to improve oxygen redox kinetics in LOBs
