Oxidative coupling of meth.ne(OCM) was conducted over LaAlO3X catalysts th.t were prepared by a coprecipitation meth.d using different co-precipitation ph.values(X = 6–10). Th. aim is to investigate th. effect of p h.values on th. catalytic activity of La AlO3 catalysts in th.s reaction. Th. results sh.wed th.t th. co-precipitation ph.value affected greatly on th. formation of ch.mical species of precipitate precursors in th. co-precipitation step, leading to different ph.ses of th. finally obtained LaAlO3 *** th. co-precipitation ph.value increased up to 8, th. lanth.num-related ph.ses such.as La2 O3 and La(Oh.3 were gradually formed as by-products, preventing th. formation of LaAlO3 perovskite crystalline structure and facilitating th. formation of oxygen vacancies on catalyst surface. h.wever, at ph.value of9 or h.gh.r, th. lanth.num content in th. precipitate precursor was increased greatly. Not LaAlO3 perovskite but lanth.num-related ph.ses were developed as main ph.ses, reducing th.ir catalytic activities in th.s reaction. Among LaAlO3 catalysts, th. one prepared at ph.= 8 sh.wed th. h.gh.st C2 yield due to its well-developed oxygen vacancies and electroph.lic lattice oxygen. Th.refore, th. co-precipitation ph.value strongly affected th. LaAlO3 catalyst activity in OCM reaction. A precious ph.control sh.uld be required to prepare various perovskite catalysts for th. OCM.

A multi-bit antifuse-type one-time programmable （OTP） memory is designed, wh.ch.h.s a smaller area and a sh.rter programming time compared with.th. conventional single-bit antifuse-type OTP memory. Wh.le th. conventional antifuse-type OTP memory can store a bit per cell, a proposed OTP memory can store two consecutive bits per cell th.ough.a data compression tech.ique. Th. 1 kbit OTP memory designed with.Magnach.p 0.18 μm CMOS （complementary metal-oxide semiconductor） process is 34% smaller th.n th. conventional single-bit antifuse-type OTP memory since th. sizes of cell array and row decoder are reduced. And th. programming time of th. proposed OTP memory is nearly 50% smaller th.n th.t of th. conventional counterpart since two consecutive bytes can be compressed and programmed into eigh. OTP cells at once. Th. layout area is 214 μm× 327 μ,, and th. read current is simulated to be 30.4 μA.

Breast cancer （BC） is a leading cause of mortality among women in th. world. To date, a number of molecules h.ve been establish.d as disease status indicators and th.rapeutic targets. Th. best known among th.m are estrogen receptor-α （ER-α）, progesterone receptor （PR） and h.ER-2/neu. About 15%-20% BC patients do not respond effectively to th.ra pies targeting th.se classes of tumor-promoting factors. Th.s, additional targets are strongly and urgently sough. after in th.rapy for h.man BCs negative for ER, PR and h.R-2, th. so-called triple-negative BC （TNBC）. Recent clinical work h.s revealed th.t CC ch.mokine ligand 5 （CCL5） is strongly associated with.th. progression of BC, particularly TNBC. h.w CCL5 contributes to th. development of TN BC is not well understood. Experimental animal studies h.ve begun to address th. mech.nistic issue. In th.s article, we will review th. clinical and laboratory work in th.s area th.t h.s led to our own h.poth.sis th.t targeting CCL5 in TNBCs will h.ve favorable th.rapeutic outcomes with.minimal adverse impact on th. general ph.siology.
