“…To demonstrate the feasibility of interconnecting NDs with biological structures, we present the formation of small ND complexes using an SP1 (Stable Protein 1, see figure 2(c) and appendix A) protein variant and first steps towards the formation of regular arrays of NDs on SP1 arrays. A crucial first step to enable both experiments is the genetic modification of SP1 to fuse 12 graphite-specific binding peptides to the SP1 N-terminus, which permit site specific binding of SP1 to the carbon sp2-hybridization which forms on the ND surface [19].…”

The realization of scalable arrangements of nitrogen vacancy (NV) centers in diamond remains a key challenge on the way towards efficient quantum information processing, quantum simulation and quantum sensing applications. Although technologies based on implanting NV-centers in bulk diamond crystals or hybrid device approaches have been developed, they are limited by the achievable spatial resolution and by the intricate technological complexities involved in achieving scalability. We propose and demonstrate a novel approach for creating an arrangement of NV-centers, based on the self-assembling capabilities of biological systems and their beneficial nanometer spatial resolution. Here, a self-assembled protein structure serves as a structural scaffold for surface functionalized nanodiamonds, in this way allowing for the controlled creation of Content from this work may be used under the terms of the Creative Commons Attribution 3.0 licence.

One-, two-as well as three-dimensional structures are within the scope of biological structural assembling techniques. We realized experimentally the formation of regular structures by interconnecting nanodiamonds using biological protein scaffolds. Based on the achievable NV-center distances of 11 nm, we evaluate the expected dipolar coupling interaction with neighboring NV-centers as well as the expected decoherence time. Moreover, by exploiting these couplings, we provide a detailed theoretical analysis on the viability of multiqubit quantum operations, suggest the possibility of individual addressing based on the random distribution of the NV intrinsic symmetry axes and address the challenges posed by decoherence and imperfect couplings. We then demonstrate in the last part that our scheme allows for the high-fidelity creation of entanglement, cluster states and quantum simulation applications.

“…The new fusion protein consisted of 12 CNT binding sites, six on each side of the ring. This enabled the creation of SP1 variants which tightly bind to CNTs to form a stable SP1/CNT complex [19]. In this work we used the same SP1 variant to attach and order the ND structures.…”

“…Meanwhile, Romero‐Sanchez et al and Donate‐Robles and Martin‐Martinez investigated the effect of calcium carbonate on the adhesion property of styrene‐butadiene‐styrene block rubber and thermoplastic polyurethane adhesives, respectively. Bahattab et al and Wolf et al also reported the adhesion behavior of polyurethane and epoxy adhesives in the presence of nanofillers in which shear and peel strength were enhanced by the addition of nanosilica and carbon nanotube fillers. Significant improvement of thermal stability and single lap shear joint strength of epoxy adhesive loaded with metallic and nonmetallic particles was observed .…”

The effect of zinc oxide and testing rate on tack, peel strength, and shear strength of styrene‐butadiene rubber (SBR)/standard Malaysian rubber (SMR L) blend adhesive was investigated using coumarone‐indene resin and toluene as the tackifying resin and solvent, respectively. Zinc oxide concentration was varied from 0–50 parts per hundred parts of rubber (phr). A Lloyd Adhesion Tester operating from 10–60 cm/min was used to determine the adhesion property. Results show that tack and peel strength increases with zinc oxide concentration up to 20 phr of the filler loading. This observation is attributed to the varying degree of wettability, which culminates at 20 phr of zinc oxide content. For the shear strength, it increases steadily with zinc oxide loading, an observation that is associated to the steady increase in cohesive strength due to the interaction between the adhesive and the filler. The adhesion property increases with testing rate and coating thickness. J. VINYL ADDIT. TECHNOL., 22:3–7, 2016. © 2014 Society of Plastics Engineers

“…Donate‐Robles and Martin‐Martinez reported that the greater the amount of precipitated calcium carbonate filler in the thermoplastic polyurethane adhesive, the greater is the initial adhesive strength. Wolf et al observed that peel strength and shear strength were improved by 50% and 24%, respectively, when less than 1 wt% of carbon nanotube/protein moiety filler was added to epoxy adhesive. On the other hand, Ghosh et al investigated the thermal and lap shear characteristics of epoxy adhesive loaded with metallic and nonmetallic particles.…”

Viscosity and adhesion properties of acrylonitrile‐butadiene rubber (NBR)‐based pressure‐sensitive adhesive were investigated by using zinc oxide as the filler. The zinc oxide loading was varied from 10 to 50 parts by weight per hundred parts of rubber (phr). Coumarone–indene resin, toluene, and polyethylene terephthalate were used as the tackifying resin, solvent, and coating substrate, respectively. Viscosity of the adhesive was measured by a Brookfield viscometer, whereas the loop tack, peel strength, and shear strength were determined by a Lloyd adhesion tester operating at 10 to 60 cm/min. Results show that viscosity increases with zinc oxide loading because of the concentration effect. Loop tack and peel strength pass through a maximum value at 20 phr of zinc oxide concentration, whereas the optimum zinc oxide loading for shear strength is 30 phr. This observation is attributed to the effect of varying degrees of wettability and compatibility of the adhesive on the substrate. In all cases, the adhesion properties of adhesives increase with coating thickness and testing rates. J. VINYL ADDIT. TECHNOL., 23:241–246, 2017. © 2015 Society of Plastics Engineers
