Superconductivity in Hourglass Dirac Chain Metals (Ti, Hf)IrGe

Advanced Science, EarlyView.
We report the discovery of ternary germanide superconductors MIrGe (M = Ti, Hf) that host hourglass Dirac chains protected by nonsymmorphic symmetry. These compounds exhibit bulk type‐II superconductivity with fully gapped states and preserved time‐reversal symmetry, as confirmed by µSR measurements.

Marker Metabolite‐Based Multi‐Omics Analysis Identifies New Loci Controlling Thousand Seed Weight in Brassica Napus

Advanced Science, EarlyView.
Marker metabolite‐based multi‐omics (genome, transcriptome, and metabolome) analysis is conducted firstly to unravel the genetic basis of thousand seed weight (TSW) in Brassica napus. The released metabolite‐QTL‐gene network represents a valuable genetic resource, and the newly validated BnaTGA6 is a promising target for the improvement of TSW in ...

A generalization of the Landesman-Lazer condition

Electronic Journal of Differential Equations, 2001
In this paper we prove the existence of solutions to the semi-linear problem $$ displaylines{ u''(x)+m^2 u(x)+g(x,u(x))=f(x)cr u(0)=u(pi)=0 }$$ at resonance.

Boosting Nanofiltration Membrane Selectivity via Amine‐Polymer Additive Engineering for Efficient Lithium Extraction From Brine

Advanced Science, EarlyView.
A diffusion‐controlled interfacial polymerization strategy incorporating poly(allylamine) (PAA) into piperazine (PIP) solution enables precise tuning of amine monomer diffusion and polyamide (PA) network formation with trimesoyl chloride (TMC). The resulting nanofiltration membranes exhibit crumpled morphology, appropriate surface charge, and enhanced ...
