The phase boundary relationship for site-bond percolation is established by generalizingthe universal relationships in pure bond percolation and pure site percolation, and the phasetransition in diluted magnetic system is studied. By using the Potts model, the phase bound-ary relationship for ferromagnetic-paramagnetic and antiferromagnetic-paramagnetic transi-tions is derived. The method adopted in this paper is convenient, simple and accurate.Especially, it has a clearer physical meaning.

Dear Editor,Soil microbial biodiversity loss caused by agricultural intensification, climate change, and the application of chemical fertilizer has become a serious problem that threatens humans (Wall et al., 2015). One phenomenon responsible for economic and food security issues is soil-borne diseases(Fisher et al., 2012), which were reported to be associated with microbial diversity loss (Shen et al., 2013;Fu et al.,2017).

Central diabetes insipidus(CDI)is a rare disease characterized by the excretion of copious amounts of diluted urine(polyuria),excess water intake(polydipsia),and a rise in serum sodium concentration(hypernatremia)(Christ-Crain et al.,2019).The neuropeptide arginine-vasopressin(AVP)is synthesized as a preprohormone along with its carrier protein neurophysin II(NPII)in hypothalamic supraoptic(SON)and paraventricular(PVN)magnocellular neurons,stored in the posterior pituitary,and secreted into the circulation.

Amphiphilic copolymers can self-assemble into nano-objects in aqueous solution.However,the selfassembly process is usually performed in a diluted solution(<1 wt%),which greatly limits scale-up production and further biomedical applications.With recent development of controlled polymerization techniques,polymerization-induced self-assembly(PISA)has emerged as an efficient approach for facile fabrication of nano-sized structures with a high concentration as high as 50 wt%.In this review,after the introduction,various polymerization method-mediated PISAs that include nitroxide-mediated polymerization-mediated PISA(NMP-PISA),reversible addition-fragmentation chain transfer polymerizationmediated PISA(RAFT-PISA),atom transfer radical polymerization-mediated PISA(ATRP-PISA),and ringopening polymerization-mediated PISA(ROP-PISA)are discussed carefully.Afterward,recent biomedical applications of PISA are illustrated from the following aspects,i.e.,bioimaging,disease treatment,biocatalysis,and antimicrobial.In the end,current achievements and future perspectives of PISA are given.It is envisioned that PISA strategy can bring great chance for future design and construction of functional nano-vehicles.

Chemical pressure induced by iso-valent doping has been widely employed to tune physical properties of materials. In this work, we report effects of chemical pressure by substitution of Sb or P into As on a recently discovered diluted magnetic semiconductor(Ba,K)(Zn,Mn)_2 As_2, which has the record of reliable Curie temperature of 230 K due to independent charge and spin doping. Sb and P are substituted into As-site to produce negative and positive chemical pressures, respectively.X-ray diffraction results demonstrate the successful chemical solution of dopants. Magnetic properties of both K-underdoped and K-optimal-doped samples are effectively tuned by Sb-and P-doping. The Hall effect measurements do not show decrease in carrier concentrations upon Sb-and P-doping. Impressively, magnetoresistance is significantly improved from7% to 27% by only 10% P-doping, successfully extending potential application of(Ba,K)(Zn,Mn)_2 As_2.

Optical studies of the CdTe/CdMnTe multiple quantum well structures with diluted manganese in barriers are presented.The combined measurements of photoluminescence and photoluminescence excitation allowed direct observation of the binding energies of n=l heavy-and light-hole free excitons.The quantitative approach of variation of exciton binding energies with well width and barrier potential height is given.The calculated and measured exciton binding energies are in good agreement.Photoluminescence studies also show exciton-acoustic phonon scattering dominates the broadening of the exciton line width up to T=50 K,while T>50 K longitudinal-optical phonon scattering contributes to the line width broadening significantly.
