Technical strategies like amino acid substitution and residue modification have been widely used to characterize the importance of key amino acids and the role that each residue plays in the structural and functional properties of protein molecules. However, there is no systematic approach to assess the impact of the…
The U.S. Department of Energy Office of Environmental Management (EM) is engaging the national laboratories to provide the scientific and technological rigor to support EM program and project planning, technology development and deployment, project execution, and assessment of program outcomes. As an early demonstrati…
The objective of this study is to develop the materials science of fiber-reinforced tungsten composites as candidates for plasma-facing components in future fusion reactors.
Abstract SmB6, a well-known Kondo insulator, exhibits a transport anomaly at low temperature. This anomaly is usually attributed to states within the hybridization gap. Recent theoretical work and transport measurements suggest that these in-gap states could be ascribed to topological surface states, which would make…
The grain-refinement mechanisms involved during the deposition of diamond films by direct-current plasma assisted chemical vapor deposition (DC-PACVD) were investigated as a function of the inter-electrode electric field (IEEF). As IEEF was increased from 260 to 940 V cm−1, the local electron temperatures near the gro…
In the past decade, passively modelocked optically pumped vertical external cavity surface emitting lasers (OPVECSELs), sometimes referred to as semiconductor disk lasers (OP-SDLs), impressively demonstrated the potential for generating femtosecond pulses at multi-Watt average output powers with gigahertz repetition r…
We developed a SERS biosensor based on gold fishnets fabricated by using e-beam lithography. This device is used for glycerophosphoinositol (GroPIns) molecule sensing. GroPIns is an abundant component of cell cytosol and high GroPIns levels have been reported in several tumour cells. We demonstrate that our SERS senso…
A plasmonic metal film with a subwavelength hole array (a mesh) is used to capture an individual subwavelength particle, like a single yeast cell or airborne dust particle, and an imaging infrared (IR) microscope, records a scatterfree, IR absorption spectrum of the particle. Individual spectra of wavelength scale par…
We present passive mode locking of a vertical external-cavity surface-emitting laser (VECSEL) in the red spectral range. The gain structure includes 20 compressively strained GaInP quantum wells (QWs), which are arranged in a resonant periodic gain design containing five packages of four quantum wells each. We use ten…
The high temperature sulphidation/oxidation behaviour of three multilayered coatings CrAlYN/CrN etched by Y+, CrAlYN/CrN etched by Cr+ and CrAlYN/CrN etched CrAl+ and the uncoated γ-TiAl (Ti–45Al–8Nb (at-%) used as reference sample was studied at 850°C for 675 h. Sulphidation/oxidation test was performed in the enviro…
We report mode-locking of an optically pumped VECSEL using a graphene-based saturable absorber mirror (GSAM). Self-starting and stable modelocked operation is demonstrated with 473 fs pulses at 1.5 GHz repetition rate and 949 nm center wavelength. Wavelength tuning is achieved over a 46 nm bandwidth. We discuss the mi…
Antibiotikaresistenz ist ein weltweites Gesundheitsproblem. Metallo-β-lactamasen katalysieren die Hydrolyse von nahezu allen β-Lactam-Antibiotika. T. D. W. Claridge, C. J. Schofield et al. zeigen in ihrer Zuschrift auf S. 3193 ff., wie 19F-NMR-Spektroskopie genutzt werden kann, um die Bindungsweise von Inhibitoren der…
Al(+3)-doped (Y,Ca)Ba2Cu3O(7-y) (YBCO) whiskers have been synthesized using a solid-state reaction technique. These materials are promising candidates for solid-state THz applications based on sequences of Josephson Junctions (IJJs). Alumina addition was systematically varied and the effect of aluminium incorporation…
A simple oxonium o-toluidinium sulfate, (C7H10N)(H3O)SO4 , crystallized from water at ambient temperature was found to be monoclinic (space group P21/c) at 100K. In the crystal, the H3O+ ions and the SO42- anions are linked by O-H…O hydrogen bonds, generating infinite layers lying parallel to the bc plane at x = 1/2.…
Recent designs in nanophotonic light-trapping technologies offer promising potential to develop high-efficiency thin-film solar cell at dramatically reduced cost. However, the lack of a cost effective scalable nanomanufacturing technique remains the main road-block. In nature, diatoms exhibit high solar energy harvest…
The interaction of biomolecules and solid-state nanomaterials at the nano-bio interfaces is a long-lasting research topic in nanotechnology. Historically, fundamental problems, such as the electron transfer, energy transfer, and plasmonic interaction at the bio-nano interfaces, have been intensively studied, and revol…
Engineering of quantum emissions is regarded as the heart of nano-optics and photonics; local density of optical states (LDOS) around the quantum emitters are critical to engineer quantum emissions, thus detection of the LDOS will impact areas related to illumination, communication, energy, and even quantum-informatic…
We investigated the effects of surface charge of gold nanoparticles (Au NPs) on photoacoustic (PA) signal from cultured cancer cell. We used citrated-coated Au NPs and poly-L-lysine-coated Au NPs as the model of negatively and positively charged Au NPs, respectively. Transmission electron microscopy (TEM) were perform…
Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder characterized by progressive muscular weakness. It affects both upper and lower motor neurons. Affected individuals typically present with either asymmetric weakness of the extremities or with bulbar symptoms (dysarthria, dysphagia). Weakness is alway…
Poly(N‐methyldodecano‐12‐lactam) (PMDL) is miscible with poly(4‐vinylphenol) (PVPh). In the system PMDL + PVPh + tetrahydrofuran containing low‐molar‐mass polymer pair, this miscible blend is soluble in the solvent. In this work, it has been found that the system containing high‐molar‐mass polymer pair undergoes assoc…
