Nanostructured mesoporous silica materials induce hormesis on chili pepper (Capsicum annuum L.) under greenhouse conditions

open access: yesHeliyon, 2022
Current agricultural practices for vegetable production are unsustainable, and the use of certain nanomaterials has shown significant potential for either plant growth promotion or defense induction in crop species.

Assessment of the adjuvant activity of mesoporous silica nanoparticles in recombinant Mycoplasma hyopneumoniae antigen vaccines

open access: yesHeliyon, 2017
The adjuvant potential of two mesoporous silica nanoparticles (MSNs), SBa-15 and SBa-16, was assessed in combination with a recombinant HSP70 surface polypeptide domain from Mycoplasma hyopneumoniae, the etiological agent of porcine enzootic pneumonia ...

Preparation of the Rutin-SBA-16 Drug Delivery System

open access: yesJournal of Biomaterials and Nanobiotechnology, 2020
This study sets out a scheme for a controlled release delivery system using SBA-16 as a carrier matrix and Rutin as a drug (Rutin-SBA-16). Physicochemical characterizations were performed to confirm the structure of the SBA-16 for post-synthesis by scanning electron microscopy (SEM), Transmission Electron Microscopy (TEM) and X-ray Diffraction (XRD ...

Catalyst Hide‐and‐Seek Beneath Porous Support Surfaces: Pinpointing Active Site Distribution Through Resonance Energy Transfer

open access: yesAngewandte Chemie, EarlyView.
Like a shark playing hide‐and‐seek in a coral reef, energy transfer (ET) finds hidden “fish” catalysts in the porous support “reef.” ET allows catalytic species to be precisely mapped, revealing whether they reside near the surface, deep in the pores, or are uniformly distributed. This approach ensures controlled catalyst distribution, highlighting how

Selective oxidation of glycerol to dihydroxyacetone using CeO2-ZrO2-Bi2O3-SnO2-supported platinum catalysts

open access: yesJournal of Asian Ceramic Societies, 2020
The effects of the Bi3+ introduction and the oxygen release and storage abilities on selective oxidation of glycerol into dihydroxyacetone (DHA) were demonstrated using Pt/CeO2-ZrO2-Bi2O3-SnO2/SBA-16 (SBA-16: Santa Barbara Amorphous No. 16) catalysts. By
