Steric Hindrance Engineering to Modulate the Closed Pores Formation of Polymer-Derived Hard Carbon for High-Performance Sodium-Ion Batteries.

The closed pores play a critical role in improving the sodium storage capacity of hard carbon (HC) anode, however, their formation mechanism as well as the efficient modulation strategy at molecular level in the polymer-derived HCs is still lacking. In this work, the steric hindrance effect has been proposed to create closed pores in the polymer-derived HCs for the first time through grafting the aromatic rings within and between the main chains in the precursor. The experimental data and theoretical calculation demonstrate that steric-hindrance effect from the aromatic ring side group can increase backbone rigidity and the internal free volumes in the polymer precursor, which can prevent the over graphitization and facilitate the formation of closed pores during the carbonization process.

Raspberry Ketone Prevents LPS-Induced Depression-Like Behaviors in Mice by Inhibiting TLR-4/NF-κB Signaling Pathway via the Gut-Brain Axis.

Scope: Depression, a prevalent mental disorder, has significantly impacted the lives of 350 million people, yet it holds promise for amelioration through food-derived phenolics. Raspberries, renowned globally for their delectable flavor, harbor a phenolic compound known as raspberry ketone (RK). However, the impact of RK on depressive symptoms remains ambiguous.

Carbohydrate metabolism and cytology of S-type cytoplasmic male sterility in wheat.

Introduction: Cytoplasmic male sterility (CMS) is an important tool for hybrid heterosis utilization. However, the underlying mechanisms still need to be discovered. An adequate supply of nutrients is necessary for anther development; pollen abortion would occur if the metabolism of carbohydrates were hampered.

Ultrasonic-antisolvent two-step assembly of carboxymethylated corn fiber gum-coated zein particles for enhanced curcumin delivery.

Zein particles (ZPs) have garnered considerable interest in delivery system construction for its capacity to encapsulate hydrophobic substances. Nonetheless, the instability of ZPs is an obstacle to application. Coating carboxymethylated corn fiber gum (CMCFG) which is a modified polysaccharide molecule enriched with anionic groups on the surface of ZPs is expected to overcome this limitation.

Characteristics of dissolved NO and indirect NO emission factor in the groundwater of high nitrate leaching areas in northwest China.

Numerous studies have demonstrated high concentrations of dissolved NO and indirect NO emission factors in groundwater affected by agriculture. However, the characteristics of seasonal and vertical dimensional difference in groundwater in high nitrate leaching areas are relatively lacking. We monitored the concentrations of dissolved and wellhead NO of 23 groundwater wells over a one year period to understand the seasonal characteristics of dissolved and wellhead NO concentrations and indirect NO emission factors (EF) of the shallow and deep groundwater in a high nitrogen leaching area and analyze the reasons for their differences.

Layered subsurface in Utopia Basin of Mars revealed by Zhurong rover radar.

Exploring the subsurface structure and stratification of Mars advances our understanding of Martian geology, hydrological evolution and palaeoclimatic changes, and has been a main task for past and continuing Mars exploration missions. Utopia Planitia, the smooth plains of volcanic and sedimentary strata that infilled the Utopia impact crater, has been a prime target for such exploration as it is inferred to have hosted an ancient ocean on Mars. However, 45 years have passed since Viking-2 provided ground-based detection results.

Effects of rare-earth light conversion film on the growth and fruit quality of sweet pepper in a solar greenhouse.

Light is an important environmental factor influencing plant growth and development. However, artificial light supplement is difficult to spread for its high energy consumption. In recent years, rare-earth light conversion film (RPO) covering is being focused on to be a new technology to study the mechanism of light affecting plant growth and development.

Multiple roles of wheat calmodulin genes during stress treatment and TaCAM2-D as a positive regulator in response to drought and salt tolerance.

Calmodulin (CaM) and calmodulin-like (CML) proteins are the most prominent calcium (Ca) sensing proteins involved in Ca-signaling processes. However, the function of these calcium sensors in wheat remains unclear. In this study, 15 TaCAMs and 113 TaCMLs were identified from the wheat reference genome.

Mining the Roles of Wheat () SnRK Genes in Biotic and Abiotic Responses.

Sucrose non-fermenting-1-related protein kinases (SnRKs) play vital roles in plant growth and stress responses. However, little is known about the SnRK functions in wheat. In this study, 149 TaSnRKs (wheat SnRKs) were identified and were divided into three subfamilies.

Dissolved greenhouse gas emissions from agricultural groundwater irrigation in the Guanzhong Basin of China.

While evidence indicates that groundwater is a potential source for greenhouse gas (GHG) emissions, information for such emissions in groundwater used for irrigation is lacking. Based on 23 wells in the mid-western Guanzhong Basin of China, we investigated the dissolved CO, NO, and CH distributions in groundwater, their relationships with water indicators, and emission fluxes during flood irrigation. We found zero methane, but CO and NO were 30 and 25 times, respectively, supersaturated compared to atmospheric concentrations.

Effects of three fertilizer application patterns on wheat sowed by machinery in slope cropland of Western Hubei, China.

Unscientific fertilization, unstable grain quality, and low profit are the key problems on wheat production in slope cropland of Western Hubei. To solve these problems, three optimized planting patterns (high nitrogen and potassium reduction, HNPR; medium nitrogen and potassium reductionm, MNPR; low nitrogen and potassium reduction, LNPR) were conducted during two consecutive years to assess their effects on wheat yield, quality, profit, and fertilizer use efficiency in Danjiangkou Reservoir area, a typical slope cropland region with wheat-maize rotation. The results showed that the application of chemical fertilizer significantly increased grain yield (GY) and wet gluten content (WGC) of wheat.

A Covalent Heterostructure of Metal Phosphide Quantum Dots Anchored in N, P Co-doped Carbon Nanocapsules for Fast and Durable Lithium Storage.

Transition-metal phosphides (TMPs) anodes for lithium ion batteries (LIBs) usually show poor rate capability and rapid capacity degradation owing to their low electronic conductivities, huge volumetric changes, as well as inferior reversibility of the discharge product LiP. Herein, a covalent heterostructure with TMPs quantum dots anchored in N, P co-doped carbon nanocapsules (NPC) has been prepared in which the P element in TMPs is simultaneously doped into the carbon matrix. As a proof of concept, CoP quantum dots covalently anchored in NPC (CoP QDs/NPC) is prepared and evaluated as an anode for LIBs.

High performance floating self-excited sliding triboelectric nanogenerator for micro mechanical energy harvesting.

Non-contact triboelectric nanogenerator (TENG) enabled for both high conversion efficiency and durability is appropriate to harvest random micro energy owing to the advantage of low driving force. However, the low output (<10 μC m) of non-contact TENG caused by the drastic charge decay limits its application. Here, we propose a floating self-excited sliding TENG (FSS-TENG) by a self-excited amplification between rotator and stator to achieve self-increased charge density, and the air breakdown model of non-contact TENG is given for a maximum charge density.
