ABSTRACT Here, we report the synthesis of glycopolymer brushes on the silicon substrate by interface‐mediated reversible addition‐fragmentation chain transfer polymerization of pentafluorophenyl acrylate as well as subsequent attachment of d‐glucosamine to determine specific and nonspecific protein interactions. The r…
/ZnO (LSMO/ZnO) interfaces exhibit extremely interesting electronic properties making them promising candidates for novel oxide p-n junctions, with multifunctional features. In this work, the structure of the interface is studied through a combined experimental/theoretical approach. Heterostructures were grown epitaxi…
Specific recognition of ultratrace levels of ions in semi‐water using super‐quicker methods is still a challenge for environmental monitoring. Herein we report a fluorescent and colormetric sensor (ZH) based on supramolecular self‐assembly, whose structure was destroyed by the addition of ultratrace of silver ions. Th…
ABSTRACT The parent repeating sequence of elastin, poly(GVGVP), was synthesized using solution phase method and characterized by 13C‐ and 1H‐NMR spectroscopy. In order to study the polymer–polymer interactions between poly(GVGVP) and hydroxyl propyl methyl cellulose (HPMC), the blends were prepared both in aqueous and…
Knowledge of a semiconductor electrode’s band edge alignment is essential for optimizing processes that occur at the semiconductor/electrolyte interface. Photocatalytic processes are particularly sensitive to such alignments, as they govern the transfer of photoexcited electrons or holes from the surface to reactants…
The preparation of redox-active coatings is a key step in fabricating electrochemical biosensors. To this goal, a variety of coating materials have been used in combination with redox-active compounds. In this study, alizarin red S (ARS) was confined in layer-by-layer (LbL) films composed of poly(ethyleneimine) (PEI)…
A 1,1-hydroboration reaction was used successfully to create brominated BN-heterocyclic compounds, which are amenable to Stille coupling reactions for the construction of new BN-heterocyclic compounds, including a new polymeric BN-heterocycle that has an extended π-conjugated backbone. The conjugated backbone of the n…
In recent years there has been resurgent interest in using biopolymers as sustainable and environmentally friendly ingredients in wood adhesive formulations. Among them, proteins and carbohydrates are the most commonly used. In this chapter, an overview is given of protein-based and carbohydrate-based wood adhesives.…
Abstract We proposed an electrical evaluation method on the basis of leakage current–stress time ( I–t ) measurement for plasma-induced damage (PID) in interlayer dielectric films. The I–t measurement, which is widely used for the time-dependent dielectric breakdown (TDDB) test is applied to the evaluation of PID in t…
Permanent-magnet vernier machines are becoming more and more attractive due to their high torque density and low-speed operating capabilities. This paper investigates the effects of the magnet thickness, magnet pole arc ratio, and slot open ratio on the torque capacity. An analytical model is first presented. It is va…
Recently, the authors have succeeded in realizing X-ray reflectivity imaging of heterogeneous ultrathin films at specific wavevector transfers by applying a wide parallel beam and an area detector. By combining in-plane angle and grazing-incidence angle scans, it is possible to reconstruct a series of interface-sensit…
Coercivity enhancement effect of the anisotropic hot-deformed NdFeB magnets made from NdFeB MQU-F powders doped with 2 wt% low-melting R70Cu30(R = Nd, Dy, and Tb) powders was explored. Post-annealing treatment at 600 °C and 700 °C was employed to modify the microstructures and therefore improve the magnetic properties…
As sustainable manufacturing becomes a mandatory requirement, more and more researchers are devoted to converting biomass as components for polymers, or as a substitution for a part of petroleum based polymers for different applications. Agricultural and forestry lignocellulosic biomass materials are mainly composed o…
Citric acid (CA) is a weak organic acid. It exists most notably in citrus fruits, after which it is named. As a commodity chemical, CA is produced on a large scale by fermentation. In this chapter, we first briefly review the applied research and methods for commercial production of CA. Then we synthesize and discuss…
Perpendicularly magnetized nanowires exhibit distinct domain wall types depending on the geometry. Wide wires contain Bloch walls, and narrow wires N\'eel walls. Here, the transition region is investigated by direct imaging of the wall structure using high-resolution spin-polarized scanning electron microscopy. An ach…
This chapter reviews progress made in red blood cell (RBC)-based hybrid nanosystems, focusing on their fabrication methods, unique attributes and applications as targeted and prolonged drug delivery systems. RBCs or erythrocytes are the most abundant, long circulating cells in the human body functioning as biological…

Armature-rail contact performance determines contact resistance between the armature and rail in electromagnetic launch, and the contact resistance directly affects the efficiency of the launch system. Besides, poor contact performance between the armature and rail will results in erosion, gouging, and other issues in…
In the search for electrochemical energy storage systems with higher energy and power at reduced cost, alternative oxidants are rarely explored. Here we revisit the oxidant dichromate (Cr 2 O 7 2– ), once used in primary batteries for telegraphs, and carry out the first assessment of its suitability for fuel cells and…
Photolysis of NO 2 is the only major pathway for O 3 formation as products from the reaction of OH and NO under atmospheric conditions in competition to the formation of HONO has been investigated experimentally and theoretically. Experiments have been carried out by directly measuring the formation of HO 2 radicals u…
