Experimental X-ray Diffraction Data for "Cooling-Induced Order-Disorder Phase Transition in CsPbBr3 Nanocrystal Superlattices"

Experimental X-ray diffraction data: -- temperature-dependent diffraction patterns (theta:2theta, rocking curves) for C18 and C8 CsPbBr3 nanocrystal superlattice samples;-- room temperature diffraction patterns (theta:2theta, rocking curves) for C6, C8, C10, C12, and C18 CsPbBr3 nanocrystal superlattices;in all files, first column is angle in degrees and the second column is intensity.

Kontanternas värde : Fattigdom och utanförskap i Sveriges digitala ekonomi

Användningen av kontanta pengar minskar och allt fler betalningar görs digitalt. Detta är en global förändring, men den är ovanligt tydlig just i Sverige. Det blir allt vanligare att kollektivtrafiken, affärer och andra serviceställen inte tar emot kontanter som betalningsmedel. Möjligheten att betala räkningar med kontanter över disk är högst begränsad; i stora delar av Sverige finns den inte all

En berättelse om att kombinera immunoterapi med ultrahypo-fraktionerad strålterapi

Sammanfattning:Denna berättelse om immunoterapi kombinerad med ultrahypo-fraktionerad strålterapi har sitt ursprung i den kliniska studie som på engelska benämdes "Brain Immune Gene Tumour Therapy" (BRIGTT) som professor Leif G, Salford i Lund initierade strax innan 2000-millienium-skiftet. Ett specifikt tumörvaccin framställdes baserat på tumörceller som han extraherade ur tumörvävnad från den gl

Low Resistivity n‐type GaN Ohmic Contacts on GaN Substrates

In this study, a report is prepared on significantly low specific contact resistivity of alloyed and non-alloyed ohmic contacts fabricated on an as-grown n+-GaN layer and measured with the transfer length method. A low ρc = 8 × 10−8 Ω cm2 is extracted for the alloyed Ti/Al/Ni/Au, and ρc = 4 × 10−7 Ω cm2 for the unannealed Ti/Pd/Au. To achieve these, a highly doped n+-GaN layer with ND = 1.5 × 1019

Harnessing Deep Eutectic Solvents for Regioselective Polar Additions to α,β Unsaturated Ketones and Aldehydes

Advancing the use of air-sensitive polar organometallic Grignard and organolithium reagents under more environmentally benign conditions, here we report the addition of these reagents to a-b unsaturated ketones and aldehydes using the deep eutetic solvent (DES) choline chloride (ChCl): glycerol (Gly) (1:2), under air. Reactions occur at room temperature within seconds with excellent regioselective

The Swedish sleep apnea registry (SESAR) cohort – “Real world data” on a national level

Introduction: The Swedish Sleep Apnea Registry (SESAR) collects clinical data from individual obstructive sleep apnea (OSA) patients since 2010. SESAR has recently been integrated with additional national healthcare data. The current analysis presents the SESAR structure and representative clinical data of a national sleep apnea cohort. Methods: Clinical data from unselected patients with a diagno

Microbial acidification by N, S, Fe and Mn oxidation as a key mechanism for deterioration of subsea tunnel sprayed concrete

The deterioration of fibre-reinforced sprayed concrete was studied in the Oslofjord subsea tunnel (Norway). At sites with intrusion of saline groundwater resulting in biofilm growth, the concrete exhibited significant concrete deterioration and steel fibre corrosion. Using amplicon sequencing and shotgun metagenomics, the microbial taxa and surveyed potential microbial mechanisms of concrete degra

Så funkar regnbågen

Efter regn kommer sol – och har man tur får man se en vackert lysande regnbåge. I Bibeln skapar Gud den som ett löfte om att inga fler syndafloder ska komma. I irländsk folktro finns en skatt vid regnbågens slut, och i den nordiska mytologin förbinder den människornas värld med Asgård. Men vad är regnbågen egentligen, och hur funkar den?

Pressure enabled organic reactions via confinement between layers of 2D materials

Confinement of reactants within nanoscale spaces of low-dimensional materials has been shown to provide reorientation of strained reactants or stabilization of unstable reactants for synthesis of molecules and tuning of chemical reactivity. While few studies have reported chemistry within zero-dimensional pores and one-dimensional nanotubes, organic reactions in confined spaces between two-dimensi

Direct band gap white light emission from charge carrier diffusion induced nanowire light-emitting diodes

Light-emitting diodes (LEDs) have been investigated during the past decades, for which a major challenge is total internal reflection that limits the light extraction efficiency. ‘Nanotree’ LEDs elegantly solve this bottleneck. Lower band gap nanowire branches are grown on higher band gap core wires. Charge carriers diffuse into the branches and recombine there. Total internal reflection is impede

Characterization of n-doped branches in nanotree LEDs

We present processed light emitting diodes (LED) devices based on GaInP core-branch nanowire (NW) structures. The LEDs rely on the charge carrier diffusion induced light emitting diode concept. The GaInP core has a higher Ga content than the branches to induce diffusion of carriers from the cores into the branches. The branches play the role of the active region in the structure, where charge carr

Insights into the morphology of Sphenothallus (Cnidaria): new features identified in an old genus from the Carboniferous (Pennsylvanian, Bashkirian) of western Ireland

The recent discovery of well-preserved fragments of Sphenothallus in the Central Clare Group (Pennsylvanian) of western Ireland provides new insights into the morphology of this enigmatic, putative cnidarian. The specimens demonstrate a morphological plasticity, including features not previously described for Sphenothallus, such as the presence of flat sides and angular lateral margins, non-bilate

Whole-channel acoustic energy and acoustophoretic efficiency frequency spectrum by the in-flow focusing method

The in-flow focusing method, introduced herein, enables rapid and straightforward measurements of the whole-channel acoustic energy of acoustic flow-through devices. The method is applied to assess the whole-channel acoustic energy and acoustophoretic efficiency frequency spectra of a bottom-actuated silicon-glass and a side-actuated glass chip. The input variables are the time-independent geometr
