Introduction Atomically dispersed transition metals embedded in nitrogendoped carbons(M–N–C) represent a typical kind of platinum group-free(PGM-free) catalyst which is considered as a potential candidate for the cathode of proton-exchange membrane fuel cells(PEMFCs) [1–3]. Apart from their low cost, the advantage of the M–N–C catalysts over PGM is further underlined by their good poisoning-resistance to impurities in fossil-derived hydrogen, such as carbon monoxide and sulfur-containing compounds [4,5].

Paper-based flexible surface-enhanced Raman scattering(SERS) chips have been demonstrated to have great potential for future practical applications in point-of-care testing(POCT) due to the potentials of massive fabrication, low cost, efficient sample collection and short signal acquisition time. In this work,common filter paper and Ag@Si O2 core-shell nanoparticles(NP) have been utilized to fabricate SERS chips based on shell-isolated nanoparticle-enhanced Raman spectroscopy(SHINERS). The SERS performance of the chips for POCT applications was systematically investigated. We used crystal violet as the model molecule to study the influence of the size of the Ag core and the thickness of the Si O2 coating layer on the SERS activity and then the morphology optimized Ag@Si O2 core-shell NPs was employed to detect thiram. By utilizing the smartphone as a miniaturized Raman spectral analyzer, high SERS sensitivity of thiram with a detection limit of 10^-9 M was obtained. The study on the stability of the SERS chips shows that a Si O2 shell of 3 nm can effectively protect the as-prepared SERS chips against oxidation in ambient atmosphere without seriously weakening the SERS sensitivity. Our results indicated that the SERS chips by SHINERS had great potential of practical application, such as pesticide residues detection in POCT.

坚持以审判为中心的诉讼制度改革是中国当前刑事司法改革的方向,庭审实质化是坚持以审判为中心的诉讼制度改革的必要组成部分。《刑事诉讼法》对关键证人出庭作证制度做出了相应的规定,但是对被告人对质询问权保障的规定还需要进一步的细化。《欧洲人权公约》第6条第3款(d)项和美国宪法第6修正案都规定了对被告人对质询问权的保障,并且在这两个地区都产生了具有指导意义的判例。欧洲人权法院对质询问权的保障经历了从"唯一、决定性规则"向"三步检验规则"的转变,美国对质询问权的保障也经历了从"可靠性标准"向"证言性陈述标准"的转变,对被告人的对质询问权起到了重要的保障作用。中国对质询问权的保障应当在现有关键证人作证制度的基础上进行细化规定,坚持证人出庭作证为原则、不出庭作证为例外,并明确规定例外情形和救济措施,从时间和空间上实现对对质询问权的保障。
