This study aimed to investigate the HS molecule adsorption on the pristine and X-doped phosphorene (X = first-row transition metal) using DFT+U method. The doping of X atoms on the phosphorene has been evaluated from energetic and electronics aspects. The binding energy values and the results of projected density of states (PDOS) analysis revealed that Ti-, V-, Fe-, and Sc-doped phosphorene have more capability to adsorb HS molecule in comparison with other systems. Moreover, the cohesive energy values showed that these (Ti, V, Fe, and Sc) doped surfaces are also energetically feasible.

Slippery liquid-infused porous surfaces (SLIPSs) are a class of surface that offers low contact angle hysteresis and low tilt angle for water droplet shedding. This property also endows the surface with pinning-free evaporation, which in turn has been exploited for analyte concentration enrichment for Surface Enhanced Raman Spectroscopic applications and antibiofouling. Herein, we demonstrate a facile approach for creating SLIPS with low contact angle hysteresis and low tilt angle for water shedding by coating the equal-volume mixture of polydimethylsiloxane (PDMS) and silicone oil.

Here, a quenching strategy was developed to create oxygen vacancies in Cu doped α-MnO. The evolutions of oxygen vacancies were directly followed by means of XRD refinement, EPR and XPS. In combination with DFT calculations and detailed characterizations, evidence is captured that oxygen vacancies not only act as direct sites for the adsorption and activation of gaseous oxygen and toluene, but also accelerate the consumption and replenishment cycle of lattice oxygen species by weakening the strength of metal-oxygen bonds.

Xylooligosaccharides (XOS), consisting 2-6 xylose residues, are a new type of prebiotic and functional oligosaccharides, and can usually be produced from the xylan-riched lignocellulosic biomass by acetic acid (HAc) hydrolysis, while the waste HAc was a problem to the environment. In this study, the main aim was to recover and reuse the waste HAc in XOS production. First, it was found that a temperature of 190 °C and a hydrolysis time of 60 min were favorable for XOS production by HAc hydrolysis, and the by-products xylose and furfural were the main inhibitors, hindering the reuse of the waste HAc.

Novel ferrite/polyurethane nanocomposites were synthesized using the in situ polymerization method after the addition of different spinel nanoferrite particles (copper, zinc, and copper-zinc) and examined as potential coatings for medical devices and implants in vascular tissue engineering. The influence of the nanoferrite type on the structure and functional characteristics of the polyurethane composites was investigated by FTIR, SWAXS, AFM, TGA, DSC, nanoindentation, swelling behavior, water contact angle, and water absorption measurements. Biocompatibility was evaluated by examining the cytotoxicity and adhesion of human endothelial cells and fibroblasts onto prepared composites and performing a protein adsorption test.

Although various biochars from different biomass materials have been developed to remediate dye-contaminated environments, the removal capabilities of pristine biochar for dyes urgently require further enhancement due to insufficient surface adsorption sites. To introduce more adsorption sites, this work proposes a simple approach to fabricate coconut shell biochar (CSB) based adsorbent by anchoring zeolitic imidazolate framework-8 (ZIF-8) via the active sites provided by polydopamine (PDA)-coated CSB. The nucleation sites provided by the PDA layer promote the dispersion of ZIF-8 on the surface of CSB, resulting in sufficient adsorption sites for removing malachite green (MG) and rhodamine B (RB) from wastewater.
