Summary What is already known about this topic?In 2018,unassisted smoking cessation(USC)was the predominant method for quitting smoking among Chinese adult smokers,accounting for 90.1%of cases.The utilization of professional smoking cessation support was comparatively low in this population.What was added by this report?In 2020,the prevalence of USC methods increased to 93.1%.Concurrently,there was a slight increase in the utilization of pharmaceuticals(from 4.6%in 2018 to 5.5%in 2020)and counseling and quit line services(from 3.2%in 2018 to 7.5%in 2020).On the other hand,the use of e-cigarettes as a cessation aid decreased from 14.9%in 2018 to 9.8%in 2020.Smokers aged 15–24 years old were more likely to rely on pharmaceutical interventions(7.9%),and less likely to choose USC methods(79.0%).What are the implications for public health practice?The promotion of professional cessation support is essential for enhancing smoking cessation rates.

The widespread applications of lithium-ion batteries(LIBs)generate tons of spent LIBs.Therefore,recycling LIBs is of paramount importance in protecting the environment and saving the resources.Current commercialized LIBs mostly adopt layered oxides such as LiCoO_(2)(LCO)or LiNi_(x)Co_(y)Mn_(1-x-y)O_(2)(NMC)as the cathode materials.Converting the intercalation-type spent oxides into conversion-type cathodes(such as metal fluorides(MFs))offers a valid recycling strategy and provides substantially improved energy densities for LIBs.Herein,two typical Co-based cathodes,LCO and LiNi_(0.6)Co_(0.2)Mn_(0.2)O_(2)(NMC622),in spent LIBs were successfully converted to CoF_(2) and(Ni_(x)Co_(y)Mn_(z))F_(2) cathodes by a reduction and fluorination technique.The as converted CoF_(2) and(Ni_(x)Co_(y)Mn_(z))F_(2) delivered cell energy densities of 650 and 700 Wh/kg,respectively.Advanced atomic-level electron microscopy revealed that the used LCO and NMC622 were converted to highly phase pure Co metal and Ni_(0.6)Co_(0.2)Mn_(0.2) alloys in the used graphite-assisted reduction roasting,simultaneously producing the important product of Li_(2)CO_(3) using only environment friendly solvent.Our study provided a versatile strategy to convert the intercalation-type Co-based cathode in the spent LIBs into conversion-type MFs cathodes,which offers a new avenue to recycle the spent LIBs and substantially increase the energy densities of next generation LIBs.

为揭示怒江干热河谷木棉种子大小的变异格局,在该气候区的不同生境采集木棉种子,测定种子生物量、直径用于量化种子大小,并借助回归模型分析种子大小随环境梯度的变化。结果显示:(1)在怒江干热河谷,木棉种子大小呈正态分布;(2)在不同干热区,种子大小依次为轻度干热区﹥中度干热区﹥重度干热区;(3)木棉种子随海拔升高而呈变小的趋势;(4)木棉种子大小的变异性随海拔(或干旱强度)上升不断减小。结论表明,木棉种子大小受到水热条件的选择压力,在稳定的水热环境中木棉种子更大,其大小的变异性也更高。

A stimuli-responsive supramolecular polymer network(G-(CN)_(2)⊂BXDSP5)with aggregation-induced emission(AIE)properties has been efficiently constructed by host-guest interactions between pillar[5]arene derivative BXDSP5 and a homoditopic guest G-(CN)_(2),which shows not only excellent fluorescence properties due to the AIE effect but also desirable ion-sensing abilities in both solution and solid states,holding great potential in the applicable fluorescence detection for Fe^(3+).The resultant G-(CN)_(2)⊂BXDSP5 can be transformed into supramolecular polymer gel at high concentration via multiple noncovalent interactions,showing multi-stimuli-responsiveness in response to temperature change,mechanical force,and competitive agent.Meanwhile,the xerogel of supramolecular polymer material has been successfully used to remove Fe^(3+)from water with high adsorption efficiency.In addition,an ionresponsive film based on supramolecular polymer has also been developed,which can serve as a practical and convenient fluorescence test kit for detecting Fe^(3+).

Sodium(Na)metal batteries(SMBs)using Na anode are potential“beyond lithium”electrochemical technology for future energy storage applications.However,uncontrollable Na dendrite growth has plagued the application of SMBs.Understanding Na deposition mechanisms,particularly the early stage of Na deposition kinetics,is critical to enable the SMBs.In this context,we conducted in situ observations of the early stage of electrochemical Na deposition.We revealed an important electrochemical Ostwald ripening(EOR)phenomenon which dictated the early stage of Na deposition.Namely,small Na nanocrystals were nucleated randomly,which then grew.During growth,smaller Na nanocrystals were contained by bigger ones via EOR.We observed two types of EOR with one involving only electrochemical reaction driven by electrochemical potential difference between bigger and smaller nanocrystals;while the other being dominated by mass transport governed by surface energy minimization.The results provide new understanding to the Na deposition mechanism,which may be useful for the development of SMB for energy storage applications.

The major obstacle for selective CO_(2)photoreduction to C_(2)hydrocarbons lies in the difficulty of C–C coupling,which is usually restrained by the repulsive dipole–dipole interaction between adjacent carbonaceous intermediates.Herein,we first construct semiconducting atomic layers featuring abundant Metal^(n+)-Metal^(δ+)pair sites(0<δ
