Summary: This study proposes a hybridstructured nanoarchitecture that combines crystalline cobalt ferrite and the amorphous parent material, which can partially increase the total magnetic moment and exhibit a larger magnetic anisotropy. By establishing a micromagnetic model, the contribution of each component can be identified, elucidating the active role of the amorphous phase. The extremely low cost, minimal complexity, and high yield of the synthesis process make this hybrid design of large interest for technological applications.

Summary: A hybrid thermal management system using liquid cooling and phase change material (PCM) is proposed in this study to extend the workable time of downhole electronics, which are prone to failure in extreme thermal environments. The performance of this system is investigated through transient flow and heat transfer simulation, showing an error of less than 6.7% when compared with reported experimental results. The results indicate that the hybrid thermal management system increases the operating time of the electronics from 230 min to 450 min and reduces the maximum temperature difference between the electronics and PCM from 30 degrees C to 2 degrees C. The effect of flow rate, spiral pipe spacing, heating power, and ambient temperature on the temperature control performance is also explored.

Summary: This study reports for the first time the incorporation of p-type functionalized carbon nanohorns (CNHs) in perovskite solar cells (PSCs) and compares them with p-type functionalized single- and double-walled carbon nanotubes (SWCNTs and DWCNTs). The p-type functionalized carbon nanomaterial (CNM) derivatives were successfully synthesized and incorporated into the hole transport layer (HTL) to evaluate their impact on PSCs. The results show that all p-type functionalized CNMs significantly improve the power conversion efficiency (PCE) by enhancing the short-circuit current density (J(sc)) and fill factor (FF). The incorporation of CNHs derivatives showed slightly better PCE compared to SWCNTs and DWCNTs derivatives. Moreover, the incorporation of p-type functionalized CNMs improves device stability by enhancing the hydrophobicity of the layer and hole transport across the interface.

Summary: This study created maps of C-3 and C-4 plant distribution and vegetation delta C-13 isoscape in Australia using a combination of field surveys and remote sensing data. The results showed that seasonal rainfall, maximum summer temperature, and soil pH were the best predictors of C-4 herbaceous cover. The approach used in this study reliably predicted the general distribution of C-3 and C-4 plants. The study also found that C-3 vegetation dominates in southern Australia, while C-4 vegetation is more prevalent in northern savannahs and grasslands.

Summary: Previous research has shown that people tend to average numeric probability forecasts when combining others' predictions. However, this study finds that when advisors express the likelihood of an event verbally, people are more likely to treat it as a certain probability and act accordingly. This effect holds true for different probability ranges, hypothetical scenarios, real events, and presentation formats.

Summary: This review provides a comprehensive summary of the material-microorganism interface in microbial hybrid electrocatalysis systems. The electron transfer at the interfaces between microorganisms and materials is a critical issue that affects system efficiency. The strategies for building efficient microorganism and material interfaces, including material design, modification, and bacterial engineering, are discussed. Understanding the interface between electrode/active materials and microorganisms could help advance the development of material-microorganism hybrid electrocatalysis systems.

Summary: In this study, we achieved bilateral pi-elongation in open-[60]fullerenes through consecutive nucleophilic additions at another site. The resulting pi-extended open-[60]fullerene contains two diaza[n]helicene (n = 5 and 6) motifs in its skeleton. Crystallographic analysis revealed close contacts of 3.09 and 3.14 angstrom between the helicene and fullerene.

Summary: In recent years, non-fused non-fullerene acceptors (NFAs) have gained attention for their simple preparation, high yield, and low cost. This study designed and synthesized three new NFAs with different terminal units but the same electron-donating unit. Halogenated NFAs showed red-shifted absorption spectra and higher electron mobilities compared to non-halogenated NFAs. The organic solar cells constructed using these NFAs demonstrated high power conversion efficiency (PCE) values, with the lowest energy loss observed for the FG6-based device. These findings suggest that non-fused NFAs have great potential for efficient and cost-effective organic solar cells.

Summary: Bis- and tris-malonates were synthesized by reacting malonate derivatives with alcohol groups with di-tert-butylsilyl bis(trifluoromethanesulfonate) and tert-butyl(trichloro)silane, respectively. These compounds were used for regioselective bis- and tris-functionalization of C-60 under Bingel conditions. By optimizing the malonate precursors with different linkers between the central Si atom and the malonate groups, specific bis- and tris-adducts with excellent regioselectivity were obtained. A complete understanding of the factors governing the regioselectivity was achieved through computational studies and analysis of the by-products. Desilylation reactions of the resulting fullerene adducts yielded acyclic fullerene adducts with alcohol functions.

The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
