Article Abstract
One-step facile synthesis of boron containing ZSM-5 microspheres is developed using 1,6-diaminohexane as the structure-directing agent and cetyltrimethylammonium bromide as the mesoporogen. High boron incorporation up to Si/B ratio of 38 is achieved and evidenced by the stretching vibrations of B-O-Si at 667 cm and 917 cm using Fourier-transform infrared spectra. The morphology of the crystals resembles berry-like spheres with sizes approximately 15 μm, which is composed of aggregated nanocrystals having sizes around 450 nm, is observed using scanning electron microscopy. The textural properties, i.e. the surface areas and pore volumes are investigated using N adsorption at -196 °C. t-plot micropore volume of 0.11 cm/g and mesopore volume of 0.14 cm/g are obtained applying this synthesis method for mesopores having pore diameters within the range of 2-10 nm.

The multi-component deep eutectic solvents (DES) have emerged as indispensable tools in the lignocellulosic pretreatment process, facilitating the efficient biotransformation of biomass sugars into valuable products. In this investigation, FeCl was ingeniously incorporated to amplify the pretreatment efficacy of a DES synthesized from cetyltrimethylammonium bromide (CTAB) and lactic acid (LA), specifically targeting poplar sawdust (PS). Remarkably, under the meticulously optimized molar ratio of 1: 4:1, this innovative ternary DES achieved an unprecedented removal of 68.

Residues of organophosphorus pesticides (OPs) raise considerable concern, while achieving high enough detection sensitivity is still a challenge for on-site fluorescence techniques. Herein, we report a "double-end samplification" strategy by encapsulating a low-emission fluorescent ion probe [DCF][P] into a cetyltrimethylammonium bromide (CTAB) hydrophobic core to form ionic luminescent micelles. At the probe end, ionic liquid micelles locally concentrated the probes, achieving a 350-fold fluorescence enhancement.

Herein, a hybrid-structured MnO cathode with self-supporting carbon cloth (CI-MnO@CC) was constructed by a nanomicellar-induced strategy cetyltrimethylammonium bromide for advanced supercapacitors. This self-supporting electrode achieves enhanced Na-ion storage ability and structure stability, which provides new insights for designing functional MnO electrodes for high-performance supercapacitors.

This research introduces an interesting approach to improve pesticide delivery to corn leaves during hot climates by developing super-amphiphilic adjuvants through amino pillar[5]arene (AP5A) and cetyltrimethylammonium bromide (CTAB) complexation. The AP5A-CTAB adjuvant functions to improve droplet retention along with spreading capabilities for resolving limitations that exist in small molecule adjuvants. The AP5A-CTAB host-guest complexation was confirmed by UV-Vis, NMR spectroscopy, and Gaussian calculations.
