A broad spectrum of electrospun organosilica membrane properties by tuning the chemical nature of the precursor building block Mater. Today Chem. (IF 7.3) Pub Date : 2024-02-06 Eva Loccufier, Sofie Verschraegen, Bianca Swanckaert, Dagmar R. D'hooge, Klaartje De Buysser, Karen De Clerck
Tetraethyl orthosilicate (TEOS) directly electrospun nanofibrous membranes are well-established for high-demanding applications. However, further expansion and exploitation of these materials require broadening the portfolio of Si-based precursors. In the present work, a part of the Si–O–Si linkages is therefore replaced by terminal groups (Si–R) or bridged organic linkages (Si-R-Si), playing with

Engineering red-emissive carbon dots for monitoring lysosomal polarity in living cells and zebrafish Mater. Today Chem. (IF 7.3) Pub Date : 2024-02-06 Jianhua Guo, Jinling Xing, Hongmei Xu, Zhenhua Yang, Wenjing Lu, Chuan Dong, Shaomin Shuang
Lysosomal polarity is an essential microenvironment parameter in biological systems that is intimately associated to a wide range of cellular statuses. Monitoring polarity fluctuations in lysosomes is extremely meaningful for investigating lysosome-related diseases. Herein, we reported the de novo design and one-step synthesis of lysosome-targeted, red-emissive carbon dots (Lyso-CDs) using Nile Blue

Ce ions intercalation and structural engineering assist MOF-derived porous V2O5 with enhanced Zn2+ diffusion kinetics for high-rate and ultra-stable aqueous zinc-ion batteries Mater. Today Chem. (IF 7.3) Pub Date : 2024-02-06 Yibo Zhang, Bo Zhao, Zhihua Li, Ziteng Guo, Mengmei Liu
Aqueous zinc-ion batteries (ZIBs) have attracted extensive attention in the energy storage systems owing to the high safety, low toxicity, and environmental friendliness. However, the sluggish reaction kinetics and inferior cycling stability of the cathode materials severely hinder the development of aqueous ZIBs. Therefore, in this work, novel Ce ions intercalated porous VO nanobelts is exquisitely

Nitrogen-doped hollow carbon spheres decorated with NiCo alloy nanoparticles for high-performance supercapacitor electrode Mater. Today Chem. (IF 7.3) Pub Date : 2024-02-06 Raju Ranjithkumar, Ji Ho Youk
Nitrogen-doped hollow carbon spheres (NHCSs) decorated with NiCo alloy nanoparticles (NPs) were prepared and examined for their prospective role as high-performance electrode materials. The NHCSs were synthesized through a silica-assisted synthesis method, followed by the decoration of NiCo alloy NPs onto the NHCSs using a simple wet impregnation method, employing a 1:1 M ratio of Co to Ni elements

Single-benzene-based fluorophores (SBBFs) with green luminescence: Improved sensitivity towards cysteine both in solution and solid state Mater. Today Chem. (IF 7.3) Pub Date : 2024-02-03 Rikitha S. Fernandes, Nilanjan Dey
We have developed a symmetric, low-molecular-weight fluorophore based on a single benzene unit with push-pull functionalities for the selective detection of cysteine. Based on the specific nucleophilic ability of thiols of cysteine, probe exhibited high selectivity and sensitivity for cysteine over other amino acids and thiols. The interaction with cysteine triggers a substitution reaction, followed

Uncovering correlations of surface reactivity and electron transport in oxide spinels Mater. Today Chem. (IF 7.3) Pub Date : 2024-02-02 F. Farshidfar, M. Lapolla, K. Ghandi
Redox reactions over transition metal oxide structures benefit from bulk charge transport and surface mass exchange, both of which depend on anion-cation interactions. This literature review is aimed at discussing the dual functionality of anions in tuning bulk electron transport and surface reactivity of spinels. As a result of this literature review, we discovered a new correlation between electron

A dual-enhancement antibacterial strategy for hierarchically functionalized surfaces with photodynamic and antifouling performance Mater. Today Chem. (IF 7.3) Pub Date : 2024-02-01 Le Chen, Hui-Min Ren, Yujie Sun, Jie Li, Zhaoyan Guo, Bingran Yu, Xiaokang Ding, Shun Duan, Fu-Jian Xu
Bacterial adhesion always occurs on various plastic surfaces in air filtration, water treatment, food processing, medical industry and many other industries. In this work, to prevent bacterial adhesion, we proposed a facile and universal antibacterial strategy to construct hierarchically structured surfaces with photodynamic and antifouling performance. Polyvinyl chloride (PVC) was taken as a representative
