Tuning Nitrogen Species in 3D Porous Carbon via Boron doping for Boosted Zn-ion Storage Capability
Tuning Nitrogen Species in 3D Porous Carbon via Boron doping for Boosted Zn-ion Storage Capability Edge located nitrogen (edge-N) species in carbon materials have been commonly recognized as one of the most active sites for Zn2+ storage, by virtue of their more accessible microstructure and lower adsorption energy barrier. However, how to modulate N species types and enrich the concentration of edge-N (pyridinic-N and pyrrolic-N) is still a daunting challenge.
Organic metal chalcogenide-assisted metabolic molecular diagnosis of central precocious puberty
Organic metal chalcogenide-assisted metabolic molecular diagnosis of central precocious puberty† Metabolic analysis in biofluids based on laser desorption/ionization mass spectrometry (LDI-MS), featuring rapidity, simplicity, small sample volume and high throughput, is expected to be a powerful diagnostic tool. Nevertheless, the signals of most metabolic biomarkers obtained by matrix-assisted LDI-MS are too limited to achieve a highly accurate diagnosis due to serious background interference.

Physicochemical Properties and Biological Characteristics of Sargassum fusiforme Polysaccharides Prepared through Fermentation of Lactobacillus
3. Results 3.1. Preliminary Characterization of SFPs As shown in , chemical composition analysis revealed that SFP and FSFP mainly contained soluble sugars, uronic acid, alginate, and fucoidan. LA-SFP and LR-SFP contained significantly lower total sugars than SFPs, and FSFP had significantly lower alginate content, indicating that LA, LP, and LR may use carbohydrates leached from S. fusiforme as a carbon source to meet their own needs for normal growth and reproduction.

Synergistic Effect of Metal-Organic Framework/Gallic Acid in Enhanced Laser Desorption/Ionization Mass Spectrometry
Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) has become an indispensable tool for high-throughput analysis of macromolecules, but many challenges still remain in detection of small molecules due to the severe matrix-related background interference in the low-molecular-weight ranges (MW < 700 Da).
Highly Efficient Planar Perovskite Solar Cells Achieved by Simultaneous Defect Engineering and Formation Kinetic Control
The formation of high quality (good morphology and low defect concentrations) perovskite films is crucial for realizing high-performance perovskite solar cells (PVSCs). Low-temperature processed perovskite films tend to have a high density of defect states, which hinder the enhancement of their device performance.
Alkoxyl Side Chain Substituted Thieno[3,4-c]pyrrole-4,6-dione To Enhance Photovoltaic Performance with Low Steric Hindrance and High Dipole Moment
A series of N-OR substituted thieno[3,4-c]pyrrole-4,6-dione (TPD) and benzo[1,2-b:4,5-b′]dithiophene (BDT) based copolymers are systematically investigated. The replacing CH with smaller size oxygen atom not only reduces the steric hindrance but also enhances the dipole moment (Δμ ), which is in favor of charge separation. while the optical and electrochemical properties almost remain unchanged due to the alkoxyl chain on TPD unit not conjugated with the backbone.
