Molecules, Vol. 29, Pages 1761: Exploring Enhanced Hydrolytic Dehydrogenation of Ammonia Borane with Porous Graphene-Supported Platinum Catalysts
In this study, we have prepared porous graphene (PG) via the process of equilibrium precipitation followed by carbothermal reduction of ZnO. During the equilibrium precipitation process, hydrolyzed N,N-dimethylformamide sluggishly generates hydroxyl groups which transform Zn2+ into amorphous ZnO nanodots anchored on reduced graphene oxide. After carbothermal reduction of zinc oxide, micropores are formed in PG. When the Zn2+ feeding amount is 0.12 mmol, the average size of the Pt nanoparticles on PG in the catalyst is 7.25 nm. The resulting Pt/PG exhibited the highest turnover frequency of 511.6 min−1 for amm...

Stable Zinc Anode Facilitated by Regenerated Silk Fibroin ‐modified Hydrogel Protective Layer
A bioinspired gel-like protective layer for the Zn anode is constructed with PVA and stabilized silk fibroin (SF). The buffer layer and abundant functional groups of SF suppress H2O activity, facilitate Zn2+ desolvation, optimize the anode interface, and control Zn nucleation/growth orientation. Their synergistic effect inhibits side reactions and prevents dendritic deposition, offering a promising strategy for stable Zn anodes. AbstractInherent dendrite growth and side reactions of zinc anode caused by its unstable interface in aqueous electrolytes severely limit the practical applications of zinc-ion batteries (ZIBs). To...

In this study, a bionanocomposite of carboxymethyl tragacanth-grafted-poly(3-aminophenol)/zinc oxide@iron oxide (CMT-g-P3AP/ZnO@Fe3O4) synthesized by in situ copolymerization as an efficient adsorbent to eliminate the acetamiprid pesticide from polluted water. The CMT-g-P3AP/ZnO@Fe3O4 magnetic nanocomposite was analyzed utilizing various techniques including FTIR, EDX, FESEM, XRD, BET, CHNSO, and TGA. The results displayed that the resulting nanocomposite with maximum adsorption capacity (Qmax) successfully removed the acetamiprid pesticide from polluted water under optimal conditions such as pH of 7.00, 5.00 mg of adsorbe...

Role of phosphate in microalgal-bacterial symbiosis system treating wastewater containing heavy metals
This study investigated the roles of phosphate on the response of the MABS system to Zn2+. The results showed that the pollutant removal effect in the MABS system was significantly reduced, and microbial growth and activity were inhibited with the presence of zinc ion (Zn2+). When phosphate and Zn2+ coexisted, the inhibition effects of pollutants removal and microbial growth rate were mitigated compared to that of only with the presence of Zn2+, with the increasing rates of 28.3% for total nitrogen removal, 37% for chemical oxygen demand removal, 78.3% for chlorophyll a concentration, and 13.3% for volatile suspended solid...

Engineered protein cages with enhanced extracellular drug release for elevated antitumor efficacy
Int J Biol Macromol. 2024 Apr 9:131492. doi: 10.1016/j.ijbiomac.2024.131492. Online ahead of print.ABSTRACTHuman heavy chain ferritin (HFn) protein cage has been explored as a nanocarrier for targeted anticancer drug delivery. Here, we introduced a matrix metalloproteinases (MMPs)-cleavable sequence into the DE loop of HFn, creating an MMP-responsive variant, MR-HFn, for localized extracellular drug release. The crystal structure of MR-HFn revealed that the addition of the MMPs recognition sequence did not affect the self-assembly of HFn but presented a surface-exposed loop susceptible to MMPs cleavage. Biochemical analysi...
