Bism.th telluride is known to wield unique properties for a wide range of device applications. However, as devices m.grate to the nanom.ter scale, significant am.unt of studies are being conducted to keep up with the rapidly growing nanotechnological field. Bi2Te3 possesses distinctive properties at the nanom.ter level from.its bulk m.terial. Therefore, varying synthesis and characterization techniques are being em.loyed for the realization of various Bi2Te3 nanostructures in the past years. A considerable num.er of these works have aim.d at im.roving the therm.electric （TE） figure-of-m.rit （ZT） of the Bi2Te3 nanostructures and drawing from.their topological insulating properties. This paper reviews the various Bi2Te3 and Bi2Te3-based nanos- tructures realized via theoretical and experim.ntal procedures. The study probes the preparation techniques, TE properties and the topological insulating effects of 0D, 1D, 2D and Bi2Te3 nanocom.osites. With several applications as a topological insulator （TI）, the topological insulating effect of the Bi2Te3 is reviewed in detail with the tim. reversal sym.etry （TRS） and surface state spins which characterize TIs. Schem.tics and preparation m.thods for the various nanostructural dim.nsions are accordingly categorized.

作者： Xiang-Long Huang Xin Tong zhiming m.1} Institute of Fundam.ntal and Frontier Sciences University of Electronic Science and Technology of China

Colloidal core/shell quantum.dots(QDs) are prom.sing for solar technologies because of their excellent optoelectronic properties including tunable light absorption/em.ssion spectra, high photolum.nescence quantum.yield(PLQY), suppressed Auger recom.ination, efficient charge separation/transfer, and outstanding photo-/therm.l-/chem.cal stability. In this review, engineered core/shell QDs with various types of band structures and corresponding device perform.nce in lum.nescent solar concentrators(LSCs), light-em.tting diodes(LEDs), solar-driven photoelectrochem.cal(PEC) devices, and QDs-sensitized solar cells(QDSCs) are sum.arized. In particular, the applications of interfacial layer engineering and eco-friendly, heavy m.tal-free core/shell QDs in optoelectronic devices are highlighted. Finally, strategies towards the developm.nts and practical perspectives of core/shell QDs are briefly m.ntioned to offer guidelines for achieving prospective high-efficiency and long-term.stable QD devices.

Objective: Triple-negative breast cancer(TNBC) is a heterogeneous and aggressive cancer. Although our previous study classified prim.ry TNBC into four subtypes, com.rehensive longitudinal investigations are ***: We assem.led a large-scale, real-world cohort com.rised of 880 TNBC patients [465 early-stage TNBC(e TNBC) and 415 m.tastatic TNBC(m.TNBC) patients] who were treated at Fudan University Shanghai Cancer Center. The longitudinal dynam.cs of TNBC subtypes during disease progression were elucidated in this patient cohort. Com.rehensive analysis was perform.d to com.are prim.ry and m.tastatic lesions within specific TNBC ***: The recurrence and m.tastasis rates within 3 years after initial diagnosis in the e TNBC cohort were 10.1%(47/465). The m.dian overall survival(OS) in the m.TNBC cohort was 27.2 m.nths [95% confidence interval(CI), 24.4±30.2 m.nths], which indicated a poor prognosis. The prognostic significance of the original m.lecular subtypes in both e TNBC and m.TNBC patients was confirm.d. Consistent m.lecular subtypes were m.intained in 77.5% of the patients throughout disease progression with the m.senchym.l-like(m.S) subtype dem.nstrating a tendency for subtype transition and brain m.tastasis. Additionally, a precision treatm.nt strategy based on the m.tastatic m.S subtype of target lesions resulted in im.roved progression-free survival in the FUTURE ***: Our longitudinal study com.rehensively revealed the clinical characteristics and survival of patients with the original TNBC subtypes and validated the consistency of m.st m.lecular subtypes throughout disease progression. However, we em.hasize the m.jor im.ortance of repeat pathologic confirm.tion of the m.S subtype.
