Size-fractionated samples of airborne particulate matter have been collected in a number campaigns at Marylebone Road, London and simultaneously background sites either Regents Park or North Kensington. Analysis these has enabled size distributions total mass elements to be determined, roadside increments attributable nonexhaust emissions arising from traffic activity calculated. Taking novel approach, the combined use distribution information tracer allowed separate estimation contributions...
Magnetic Weyl semimetals (WSMs)—materials that host exotic quasiparticles called fermions—must break either spatial inversion or time-reversal symmetry. A number of WSMs symmetry have been identified, but showing unambiguously a material is time-reversal-breaking WSM tricky. Three groups now provide spectroscopic evidence for this latter state in magnetic materials (see the Perspective by da Silva Neto). Belopolski et al. probed Co 2 MnGa using angle-resolved photoemission spectroscopy,...
Abstract. Black carbon aerosols (BC) at a London urban site were characterised in both winter- and summertime 2012 during the Clean Air for (ClearfLo) project. Positive matrix factorisation (PMF) factors of organic aerosol mass spectra measured by high-resolution spectrometer (HR-AMS) showed traffic-dominant sources summer but winter influence additional non-traffic became more important, mainly from solid fuel (SF). Measurements using single particle soot photometer (SP2, DMT), BC exhibited...
Topological semimetals can be classified by the connectivity and dimensionality of band crossings in momentum space. The a Dirac, Weyl, or an unconventional fermion semimetal are zero-dimensional (0D) points, whereas nodal-line one-dimensional (1D) closed loops. Here we propose that presence perpendicular crystalline mirror planes protect three-dimensional (3D) characterized nontrivial links such as Hopf link coupled chain, giving rise to variety new types topological semimetals. We show...
Layered kagome-lattice 3d transition metals are emerging as an exciting platform to explore the frustrated lattice geometry and quantum topology. However, typical kagome electronic bands, characterized by sets of Dirac-like band capped a phase-destructive flat band, have not been clearly observed, their orbital physics even less well investigated. Here, we present close-to-textbook bands with differentiation in CoSn, which can be described minimal tight-binding model single-orbital hopping...
CsV${}_{3}$Sb${}_{5}$ has been recently discovered to be a kagome superconductor. Here, the authors use scanning tunneling microscopy study its charge order and superconductivity at atomic scale. Through mapping energy gap of order, identify chiral electronic nature. They also elucidate surface nature 1$\ifmmode\times\else\texttimes\fi{}$4 superlattice superconducting excitations.
Superconductors with kagome lattices have been identified for over 40 years, a superconducting transition temperature ${T}_{c}$ up to 7 K. Recently, certain superconductors found exhibit an exotic charge order, which intertwines superconductivity and persists being one order of magnitude higher than ${T}_{c}$. In this work, we use scanning tunneling microscopy study the in superconductor $\mathrm{Rb}{\mathrm{V}}_{3}{\mathrm{Sb}}_{5}$. We observe both $2\ifmmode\times\else\texttimes\fi{}2$...
Magnetic topological phases of quantum matter are an emerging frontier in physics and material science. Along these lines, several kagome magnets have appeared as the most promising platforms. However, magnetic nature materials presence state remains unsolved issue. Here, we explore correlations magnet Co_3Sn_2S_2. Using muon spin-rotation, present evidence for competing orders lattice this compound. Our results show that while sample exhibits out-of-plane ferromagnetic ground state,...
Exploration of the topological quantum materials with electron correlation is at frontier physics, as strong interaction may give rise to new phases and transitions. Here we report that a family kagome magnets $R{\mathrm{Mn}}_{6}{\mathrm{Sn}}_{6}$ manifest transport properties analogical those in quantum-limit Chern magnet ${\mathrm{TbMn}}_{6}{\mathrm{Sn}}_{6}$. The family, including oscillations nontrivial Berry phase large anomalous Hall effect arising from curvature field, points...
Abstract Unconventional superconductors often feature competing orders, small superfluid density, and nodal electronic pairing. While unusual superconductivity has been proposed in the kagome metals A V 3 Sb 5 , key spectroscopic evidence remained elusive. Here we utilize pressure-tuned ultra-low temperature muon spin spectroscopy to uncover unconventional nature of RbV KV . At ambient pressure, observed time-reversal symmetry breaking charge order below...
Abstract Hepatitis B virus (HBV) infection is a major risk factor for hepatocellular carcinoma (HCC), but its pathogenic mechanism remains to be explored. The RNA N 6 -methyladenosine (m A) reader, YTH (YT521-B homology) domain 2 (YTHDF2), plays critical role in the HCC progression. However, function and regulatory mechanisms of YTHDF2 HBV-related remain largely elusive. Here, we discovered that O-GlcNAcylation was markedly increased upon HBV infection. O-GlcNAc transferase (OGT)-mediated on...
