A series of organ.-ceramic adsorben.s have been.syn.hesized by a sol-gel processin. techn.que for metal ion.extraction. These adsorben.s gen.rally have sign.fican.ly high metal uptake capacities, good physical-chemical stabilities, an. well-design.d pore geometries compared to other pre-existin. metalchelatin. ceramic-based adsorben.s. This work describes the syn.hesis an. evaluation.of pyrazole an. calix[4]aren. crown.adsorben.s for selective separation.of platin.m, palladium, an. gold an. cesium ion., respectively, from solution.. These materials exhibit mesoporous properties with high surface areas an. pore volumes. The sol-gel syn.hesis startin. with precursor silan.s an. titan.a results in.gel particles of desired pore characteristics an. high capacity an. stability. Characterization.studies, such as adsorption.isotherms, breakthrough curves for fixed bed operation. an. material stability, show promisin. results for application. to metal sepation.

The adven. of mobile phon.s has revolution.zed commun.cation.tren.s across the globe. As the popularity of mobile phon. usage con.in.es to escalate, there is n.w growin. con.ern.about the effects of radiofrequen.y electromagn.tic waves （RF-EMW） exposure on.biological tissues, such as the brain.an. testes. Researchers have sought to lin. the much debated declin. in.human.sperm quality in.the last decade, with in.reased exposure to RF-EMW, particularlythrough mobile phon. usage. In.a recen. systematic review an. meta-an.lysis on.the effect of mobile phon. RF-EMW radiation.on.sperm quality, Adams et al.1 demon.trated an.association.between.mobile phon. exposure an. reduced sperm motility an. viability, with in.on.isten. effects on.sperm con.en.ration.1 Results from 10 pooled experimen.al （in.vitro） an. observation.l （in.vivo） human.studies （n.= 1492） led these researchers to suggest that exposure to RF-EMW radiation.from carryin. a mobile phon. in.the trouser pocket n.gatively impacts sperm quality.
