Stereoselective Double Reduction of 3-Methyl-2-cyclohexenone, by Use of Palladium and Platinum Nanoparticles, in Tandem with Alcohol Dehydrogenase [PDF]

Nanomaterials, 2018
The combination of metal nanoparticles (Pd or Pt NPs) with NAD-dependent thermostable alcohol dehydrogenase (TADH) resulted in the one-flask catalytic double reduction of 3-methyl-2-cyclohexenone to 3-(1S,3S)-methylcyclohexanol.

Exploration of In Situ Extraction for Enhanced Triterpenoid Production by Saccharomyces cerevisiae. [PDF]

Microb Biotechnol
In situ extraction using isopropyl myristate (IPM) and β‐cyclodextrins (β‐CDs) enhances the production of triterpenoids in engineered Saccharomyces cerevisiae by facilitating the continuous extraction of intracellular products, thereby simplifying downstream processing and improving overall yield. ABSTRACT Plant‐derived triterpenoids are in high demand

Near‐Unity Superradiant Emission from Delocalized Frenkel Excitons in a Two‐Dimensional Supramolecular Assembly

Advanced Optical Materials, Volume 11, Issue 2, January 18, 2023., 2023
Mitigation of nonradiative losses in the superradiant emission from supramolecular assemblies leads to a room temperature molecular fluorophore with an unprecedented combination of fast emissive lifetime (174 ps) and a high quantum yield (82%). Structural and optical studies reveal the deleterious effects of a small number of impurity and defect sites ...

Corrosion protection of  Zn–Al–Mg‐coated steel by a layered double hydroxide conversion layer

Materials and Corrosion, Volume 73, Issue 10, Page 1657-1665, October 2022., 2022
This study investigates the potential of layered double hydroxide (LDH) conversion layers synthesized by an environmental and toxicological uncritical process to increase the corrosion resistance of Zn–Al–Mg (ZM) coated steel. LDH layers prepared within industrial feasible reaction times as short as 30 s significantly decrease the corrosion rate of the

Hybrid connection technologies for hollow sections in steel construction

Steel Construction, Volume 15, Issue S1, Page 37-50, May 2022., 2022
Abstract Circular hollow sections (CHS) offer a variety of constructional and architectural advantages. Up to now, hollow section structures have usually been connected by welding, and more rarely by bolting. However, these established connection methods have disadvantages.

Machine learning and finite element analysis: An integrated approach for fatigue lifetime prediction of adhesively bonded joints

Fatigue &Fracture of Engineering Materials &Structures, Volume 44, Issue 12, Page 3334-3348, December 2021., 2021
Abstract Since fatigue investigations are expensive and time consuming, models capable of predicting lifetime by leveraging existing experimental data are desirable. Here, this task is accomplished by combining machine learning (ML) and finite element analysis (FEA).

Characterizing standard genetic parts and establishing common principles for engineering legume and cereal roots

Plant Biotechnology Journal, Volume 17, Issue 12, Page 2234-2245, December 2019., 2019
Summary Plant synthetic biology and cereal engineering depend on the controlled expression of transgenes of interest. Most engineering in plant species to date has relied heavily on the use of a few, well‐established constitutive promoters to achieve high levels of expression; however, the levels of transgene expression can also be influenced by the ...
