Cross section measurements of the e + e − → D *+ D *− and e + e − → D *+ D − processes at center-of-mass energies from 4.085 to 4.600 GeV

open access: yesJournal of High Energy Physics, 2022
The Born cross sections of the e + e − → D *+ D *− and e + e − → D *+ D − processes are measured using e + e − collision data collected with the BESIII experiment at center-of-mass energies from 4.085 to 4.600 GeV, corresponding to an integrated ...

A critical point in the distribution of lepton energies from the decay of a spin-1 resonance

open access: yesJournal of High Energy Physics, 2019
We consider a spin-1 resonance produced with an arbitrary spectrum of velocities and decaying into a pair of massless leptons, and we study the probability density function of the energy of the leptons in the laboratory frame.

Functional Recycling and Reuse of Nd–Fe–B Permanent Magnets from Various Waste Streams for a more Sustainable and Resilient Electromobility

open access: yesAdvanced Engineering Materials, EarlyView.
Due to the increasing demand and growing importance of resilient and sustainable supply chains, the use of recycled and reused Nd–Fe–B magnets in e‐mobility applications such as Pedelecs, e‐Scooters, and Hoverboards is being investigated. It can be shown that the corresponding motors with recycled magnets do not exhibit any loss of performance while at

Dalitz plot analysis of the D + → K − K + K + decay

open access: yesJournal of High Energy Physics, 2019
The resonant structure of the doubly Cabibbo-suppressed decay D +→K − K + K + is studied for the first time. The measurement is based on a sample of pp-collision data, collected at a centre-of-mass energy of 8 TeV with the LHCb detector and corresponding

Baryon Interactions in Nuclear and Hypernuclear Matter

open access: yes, 2003
The production and structure of Λ hypernuclei are investigated in field theoretical models. The production in coherent p+A reactions is investigated by means of a resonance model.

Microstructure, Mechanical Properties, and Antibacterial Performance of Novel Fe‐Mn‐Zn Nanocrystalline Alloys Produced by Mechanical Alloying

open access: yesAdvanced Engineering Materials, EarlyView.
This article presents the development of Fe‐Mn‐Zn nanocrystalline alloys (0–9 wt% Zn) by mechanical alloying and subsequently hot pressing. Their microstructure, density, hardness, wear resistance, corrosion behavior, and antibacterial properties are systematically examined.

Constructing Covalent Organic Polymers through Dative B─N Bonds: Synthesis, Single Crystal Structures, and Physical Properties

open access: yesAdvanced Functional Materials, EarlyView.
Dynamic linkages are highly attractive in preparing single crystals of covalent organic polymers (COPs). Here, single crystals of two COPs CityU‐15 and CityU‐16 based on reversible B─N bonds are constructed using tetra(4‐pyridyl)tetrathiafulvalene and tetra(4‐pyridyl)porphine as monomers.
