Highly Efficient Polarization Control Based on All-Dielectric Metasurfaces

open access: yesIEEE Access, 2022
Metasurfaces have been widely used in the manufacture of various optical components in recent years. Based on all-dielectric metasurfaces, we proposed broadband, high-efficiency (over 83%) quarter-wave plates (QWP) and half-wave plates (HWP ...

A Bifunctional Copper Catalyst Enables Ester Reduction with H2: Expanding the Reactivity Space of Nucleophilic Copper Hydrides [PDF]

open access: yes, 2021
Employing a bifunctional catalyst based on a copper(I)/NHC complex and a guanidine organocatalyst, catalytic ester reductions to alcohols with H2 as terminal reducing agent are facilitated.

Design and Engineering of an Artificial Bifunctional N-Deacetylase/N-Sulfotransferase for the Biosynthesis of N-Sulfated Heparosan. [PDF]

open access: yesAdv Sci (Weinh)
An artificial bifunctional N‐deacetylase/N‐sulfotransferase was engineered in Escherichia coli by combining screened N‐deacetylases with an NST domain. The integrated engineering strategy improved enzyme performance. The optimized enzyme efficiently converted heparosan into N‐sulfated heparosan, addressing a key bottleneck in microbial heparin ...

A Novel Bifunctional Wax Ester Synthase Involved in Early Triacylglycerol Accumulation in Unicellular Green Microalga Haematococcus pluvialis Under High Light Stress

open access: yesFrontiers in Bioengineering and Biotechnology, 2022
The bulk of neutral lipids, including astaxanthin esters and triacylglycerols (TAGs), are accumulated in the green microalga Haematococcus pluvialis under high light (HL) stress. In this study, a novel bifunctional wax ester synthase (WS) gene was cloned

Environmentally Benign Bifunctional Solid Acid and Base Catalysts [PDF]

open access: yes, 2014
Solid bifunctional acid–base catalysts were prepared in two ways on an amorphous silica support: (1) by grafting mercaptopropyl units (followed by oxidation to propylsulfonic acid) and aminopropyl groups to the silica surface (NH2–SiO2–SO3H), and (2) by ...

CD40- and CD95-specific antibody single chain-Baff fusion proteins display BaffR-, TACI- and BCMA-restricted agonism

open access: yesmAbs, 2020
Antibodies that target a clinically relevant group of receptors within the tumor necrosis factor receptor superfamily (TNFRSF), including CD40 and CD95 (Fas/Apo-1), also require binding to Fc gamma receptors (FcγRs) to elicit a strong agonistic activity.

Novel Polymer–Silica Composite-Based Bifunctional Catalysts for Hydrodeoxygenation of 4-(2-Furyl)-3-Buten-2-One as Model Substance for Furfural–Acetone Aldol Condensation Products

open access: yesApplied Sciences, 2019
Novel bifunctional metal-loaded polymer−silica composite (PSC) catalysts were investigated in the hydrodeoxygenation (HDO) of 4-(2-furyl)-3-buten-2-one (FAc) as a model substance for furfural−acetone aldol condensation products. PSC catalysts
