Abstract BACKGROUND Methyl lactate is widely applied in the chemical, food, cosmetics and pharmaceutical industries. The conversion of carbohydrates over heterogeneous catalysts to methyl a promising environmentally benign process. RESULTS Hierarchical Sn‐Beta zeolite (Sn‐Beta) corresponding bimetal‐doped Beta zeolites (M‐Sn‐Beta; M = Zn, In, La, Ga, Ni) were prepared via novel modified hydrothermal synthesis method convert into lactate. introduction Zn considerably improved yield from...

Abstract: Titanium implants have been widely used for many medical applications, but bacterial infection after implant surgery remains one of the most common and intractable complications. To this end, long-term antibacterial ability surface is highly desirable to prevent implant-associated infection. In study, a novel coating containing new agent, (Z-)-4-bromo-5-(bromomethylene)-2(5H)-furanone loaded poly(L-lactic acid) nanoparticles, was fabricated on microarc-oxidized titanium purpose....

Dental implants have become increasingly common for the management of missing teeth. However, peri-implant infection remains a problem, is usually difficult to treat, and may lead eventually dental implant failure. The aim this study was fabricate novel antibacterial coating containing halogenated furanone compound, ie, (Z-)-4-bromo-5-(bromomethylene)-2(5H)-furanone (BBF)-loaded poly(L-lactic acid) (PLLA) nanoparticles on microarc-oxidized titanium evaluate its release behavior in...

Thermally expanded graphene oxide supported PtAu alloy nanoparticles showed high catalytic activity in the oxidation of glycerol base-free aqueous solution.

Abstract: To prevent peri-implant infection, a new antibacterial coating containing halogenated furanone compound, ( Z -)-4-bromo-5-(bromomethylene)-2(5 H )-furanone-loaded poly(l-lactic acid) nanoparticles, has been fabricated. The current study was designed to evaluate the preventive effect of under simulated environment infection in vivo. Microarc-oxidized titanium implants treated with minocycline hydrochloride ointment were used as positive control group, and microarc-oxidized without...

Abstract With different template agents (blank, macromolecule polyvinyl alcohol PVA and micromolecule cetyltrimethylammonium bromide CTAB), nanoparticle‐like polypyrrole (PPyNP), nanosphere‐like (PPyNS) nanowire‐like (PPyNW) were synthesized respectively by in‐situ polymerization. Interestingly, the diameter of PPyNS was about 108–160 nm adjusting mass PVA, while width range PPyNW 63–87 regulating CTAB. Also, electrochemical properties as‐obtained PPy with rich morphologies investigated in...

Abstract Two crystals based on cucurbit[5]uril and cucurbit[7]uril, C30H30N20O10·2CF3SO3H·7.25H2O (1) C42H42N28O14·CF3SO3H·8H2O (2) have been synthesized in trifluoromethanesulfonic acid structurally determined by single-crystal X-ray diffraction analyses. These two crystal structures demonstrated that the highly-ordered trifluoromethanesulfonate anions play essential roles formation of three-dimensional supramolecular frameworks with 1D elliptical channels or circular channels.

Abstract In this paper, uniformly transition metal oxide (MoO 3 ) nanosheets were electrochemically deposited on flexible carbon cloth (CC), and then conductive polyaniline (PANI) was orderly wrapped around their surface by electrochemical polymerization. The morphology structure of as‐obtained self‐supported PANI/MoO /CC electrode investigated FTIR, X‐ray diffraction, Raman, scanning electron microscope (SEM), transmission microscopy (TEM), photoelectron spectroscopy measurements in detail....

Abstract BACKGROUND The chemical catalytic conversion of carbohydrates into γ‐valerolactone (GVL) is a sustainable alternative to the petrochemical process starting from depleting fossil resources. Direct (fructose, glucose, starch and cellulose) GVL was achieved via combined heteropoly acid based SO 3 H‐functionalized ionic liquid (HAIL) supported ruthenium (Ru) catalyst system in one pot water media. RESULTS A 63% yield (based on fructose) obtained under catalysis...

Abstract Although biodegradable and biocompatible polymers have great advantages as a research hotspot, the single polymer does not satisfy multifunctional needs in biomaterials application. Herein, carbon dots (CDs) with strong fluorescence good hydrophilicity were prepared through effective microwave method from citric acid ethanediamine. Then green PCL@CDs fabricated by ring‐opening polymerization (ROP) of ε‐caprolactone (ε‐CL) via phytic active CDs catalysts. Importantly, as‐obtained...

76% Yield of levulinic acid was obtained from fructose conversion catalyzed by acidic ionic liquid in water.The chemical structures and morphologies humin byproduct were investigated, indicating three stages transition for the first time.At early stage, 5-hydroxymethylfurfural (HMF) intermediate dehydration can take part formation through two sites.When HMF completely converted, humins react further on aldehyde groups, as evidenced disappearance 2-formylfuran rings.If reaction time long...

We propose a new approach for the synergistic conversion of cellulose into levulinic acid (LA) by SO 3 H-functionalized ionic liquid (SFIL) and lanthanide chloride (LnCl ) in water. Compared to that with 1-methyl-3-(3-sulfopropyl)imidazolium ([MIMPS]Cl) only, LA yield [MIMPS]Cl ErCl was improved at most 14.4% 13.6% 50 mol% IL 30 IL, respectively, which indicating coordination between is prominent. Moreover, combined system could endure high concentration substrate remained activity eleventh...
