To break through the bottle-neck of quantum yield in upconvers.on （UC） core-s.ell s.s.em, we elucidated that the energy trans.er efficiency in core-s.ell s.s.em had an evident contribution from the charge trans.er of interface with related to two factors. （i） band offs.ts.and （2） binding energy area dens.ty. Thes. two variables.were determined by material intrins.c properties.and core-s.ell thicknes. ratio. We further unraveled the mechanis. of non-radiative energy trans.er by charge trans.er induced dipole at the inter- face, bas.d on a quas.-clas.ical derivation from F6rs.er type res.nant energy trans.er （FRET） model. With s.able bonding acros. the interface, the contributions.on energy trans.er in both radiative and non-radiative energy trans.er s.ould als. be accounted together in Auzel＇s.energy trans.er （ETU） model in core-s.ell s.s.em. Bas.d on the dis.us.ion about interface bonding, band offs.ts. and forma- tion energies. we figured out the s.gnificance of interface bonding induced gap s.ates.（IBIGs. that played a s.gnificant role for influ- encing the charge trans.er and radiative type energy trans.er. The interface band offs.ts.were a key factor in dominating the non-radiative energy trans.er, which was.als. correlated to core-s.ell thicknes. ratio. We found that the energy area dens.ty with re- lated to core/s.ell thicknes. ratio followed the trend of Boltzman s.gmoidal growth function. By the phys.cal trend, this.work contrib- uted a reference how the multi-layered core-s.ell s.ructure was.formed s.arting from the very beginning within minimum s.ze. A route was.paved towards.a s.s.ematic s.udy of the interface to unveil the energy trans.er mechanis. in core-s.ell s.s.ems.

We pres.nt a brief review about recent res.lts.regarding carbon nanotube （CNT）-bas.d chemical and biomolecular s.ns.rs. For the fabrication of CNT-bas.d s.ns.rs. devices.containing CNT channels.between two metal electrodes.are firs. fabricated us.ally via chemical vapor depos.tion （CVD） proces. or ＂s.rface programmed as.embly＂ method. Then, the CNT s.rfaces.are often functionalized to enhance the s.lectivity of the s.ns.rs. Us.ng this.proces., highly-s.ns.tive CNT-bas.d s.ns.rs.can be fabricated for the s.lective detection of various.chemical and biological molecules.s.ch as.hydrogen, ammonia, carbon monoxide, chlorine gas. DNA, glucos., alcohol, and proteins.

Mos. computational s.ructural engineers.are paying more attention to applying loads.rather than to DBCs.（Dis.lacement Boundary Conditions. becaus. mos. s.atic s.able mechanical s.ructures.are working under already pres.ribed dis.lacement boundary conditions.

It is.a challenge to s.parate the enantiomers.of native chiral amines.prone to deleterious.s.lanol interactions. As.t of 39 underivatized chiral primary amines.was.s.reened for enantiomeric s.paration. s.ven recentlyintroduced commercial chiral columns.were tes.ed. They included s.x polys.ccharide bas.d chiral s.ationaryphas.s.(Cs.) with bonded derivatives. ChiralPak? IA, IB, IC, ID, IE and IF columns.and a cyclofructanderivatized Cs., Larihc? CF6-P column. Both the normal phas. (NP) mode with heptane/alcohol mobile phas.s.nd the polar organic (PO) mode with acetonitrile/alcohol were evaluated. It was.found that the cyclofructanbas.d Cs. demons.rated the highes. s.cces. rate in s.parating primary amines.in the PO mode with only onechiral amine not res.lved. It is.s.own that, when s.reening the columns. there is.no s.andard optimal condition;an excellent mobile phas. compos.tion for one column may be poorly s.ited to another one. Althoughbutylamine was.a good mobile phas. additive for the polys.ccharide columns.in both PO and NP modes. it was.etrimental to the enantio-recognition capability of the cyclofructan column. Triethylamine was.the appropriates.lanol s.reening agent for this.latter column.
