Nanoscale thermal control of a single living cell enabled by diamond heater-thermometer
Aleksandra Radenovic, Evgenii Glushkov
We report a new approach to controllable thermal stimulation of a single living cell and its compartments. The technique is based on the use of a single polycrystalline diamond particle containing silicon-vacancy (SiV) color centers. Due to the presence of ...
NATURE PORTFOLIO2023Ultralong 100 ns spin relaxation time in graphite at room temperature
László Forró, Bálint Náfrádi, Péter Szirmai, Bence Gábor Márkus
Graphite has been intensively studied, yet its electron spins dynamics remains an unresolved problem even 70 years after the first experiments. The central quantities, the longitudinal (T-1) and transverse (T-2) relaxation times were postulated to be equal ...
NATURE PORTFOLIO2023The carbon intensity of integrated photovoltaics
Christophe Ballif, Alessandro Francesco Aldo Virtuani, Alejandro Borja Block
To assess the meaningfulness of installing solar photovoltaics in buildings and infrastructures, we consider a carbon intensity (CI) balance perspective and assess whether installing PV at different orientations acts as a net CO2 sink or source, when compa ...
2023Flowing Gas Experiments Reveal Mechanistic Details of Interfacial Reactions on a Molecular Level at Knudsen Flow Conditions
Christian Ludwig, Michel Rossi, Riccardo Iannarelli
Knudsen flow experiments and its interpretation in terms of adsorption/desorption kinetics as well as quantitative uptake on substrates of interest is presented together with the description of critical design parameters of the Knudsen Flow Reactor (KFR). ...
2022Preparation of amorphous bismuth films by quenched condensation insode of a superconducting magnet
Topological phases in crystalline materials have drawn intense research interest due to their fundamentally unique properties and potential for applications ranging from quantum computation to spintronics. Recently, scientists have extended the theoretical ...
2022Streamlined Alkylation via Nickel-Hydride-Catalyzed Hydrocarbonation of Alkenes
Xile Hu, Chao Fan, Srikrishna Bera, Zhikun Zhang
Compounds rich in sp(3)-hybridized carbons are desirable in drug discovery. Nickel-catalyzed hydrocarbonation of alkenes is a potentially efficient method to synthesize these compounds. By using abundant, readily available, and stable alkenes as pro-nucleo ...
AMER CHEMICAL SOC2022Quantum vibronic effects on the electronic properties of solid and molecular carbon
Michele Ceriotti, François Gygi, Han Yang
We study the effect of quantum vibronic coupling on the electronic properties of carbon allotropes, including molecules and solids, by combining path integral first principles molecular dynamics (FPMD) with a colored noise thermostat. In addition to avoidi ...
AMER PHYSICAL SOC2021Growth of Graphene Nanoflakes/h-BN Heterostructures
Klaus Kern, Uta Schlickum, Daniel Pablo Rosenblatt, Sebastian Koslowski
2D materials such as graphene, hexagonal boron nitride (h-BN), or transition metal dichalcogenides, and their heterostacks are gaining increasing interest because of their extraordinary properties, which can range from superconductivity to large charge car ...
WILEY2021Additive Manufacturing of Bulk Metallic Glasses-Process, Challenges and Properties: A Review
Roland Logé, Jamasp Jhabvala, Navid Sohrabi
Bulk Metallic Glasses (BMG) are metallic alloys that have the ability to solidify in an amorphous state. BMGs show enhanced properties, for instance, high hardness, strength, and excellent corrosion and wear resistance. BMGs produced by conventional method ...
MDPI2021High Sensitivity Detection of a Solubility Limiting Surface Transformation of Drug Particles by DNP SENS
David Lyndon Emsley, Arthur César Pinon, Jasmine Viger-Gravel
We investigate the presence of a surface species for the active pharmaceutical ingredient (API) AZD9496 with dynamic nuclear polarization surface enhanced nuclear spectroscopy (DNP SENS). We show that using DNP we can elucidate the presence of an amorphous ...
