Adsorptive separation of acetylene/carbon dioxide mixtures by porous materials is an important and challenging task due to their similar sizes and physical properties.Here,remarkable acetylene/carbon dioxide separation featuring a high dynamic breakthrough capacity for acetylene(4.3 mmol·g^(–1))as well as an ultralow acetylene regeneration energy(29.5 kJ·mol^(–1))was achieved with the novel TiF_(6)^(2–)-pillared material ZU-100(TIFSIX-bpy-Ni).Construction of a pore structure with abundant TiF_(6)^(2–)anion sites and pores with appropriate sizes enabled formation of acetylene clusters through hydrogen bonds and intermolecular interactions,which afforded a high acetylene capacity(8.3 mmol·g^(–1))and high acetylene/carbon dioxide uptake ratio(1.9)at 298 K and 1 bar.Moreover,the NbO_(5)^(2–)anion-pillared material ZU-61 investigated for separation of acetylene/carbon dioxide.In addition,breakthrough experiments were also conducted to further confirm the excellent dynamic acetylene/carbon dioxide separation performance of ZU-100.

Linear cryptanalysis is one of the most important cryptanalytic tools against block ciphers,thus modern block ciphers are always deliberately devised to avoid good long linear characteristics so as to resist linear cryptanalysis and its extensions. Differential-linear cryptanalysis, a powerful extension of linear cryptanalysis, has drawn much attention due to its applicability even in certain case that there is no good long linear characteristic of block ciphers. To further refine differential-linear cryptanalysis, we investigate the correlation distribution of differential-linear hull over random permutation and derive a concrete and concise correlation distribution accordingly. Theoretically, this could make differential-linear cryptanalysis more reasonable and precise. Moreover, the newly-proposed correlation distribution could lead to an interesting potential for improving the effectiveness of differential-linear cryptanalysis.

Piccolo is a lightweight block cipher that adopts a generalized Feistel network structure with4 branches, each of which is 16 bit long. The key length is 80 or 128 bit, denoted by Piccolo-80 and Piccolo-128, respectively. In this paper, we mounted meet-in-the-middle attacks on 14-round Piccolo-80 without preand post-whitening keys and 18-round Piccolo-128 with post-whitening keys by exploiting the properties of the key schedule and Maximum Distance Separable（MDS） matrix. For Piccolo-80, we first constructed a 5-round distinguisher. Then 4 rounds and 5 rounds were appended at the beginning and at the end,respectively. Based on this structure, we mounted an attack on 14-round Piccolo-80 from the 5 th round to the 18 th round. The data, time, and memory complexities were 2;chosen plaintexts, 2;encryptions, and 2;blocks, respectively. For Piccolo-128, we built a 7-round distinguisher to attack 18-round Piccolo-128 from the 4 th round to the 21st round. The data, time, and memory complexities were 2;chosen plaintexts,2;encryptions, and 2;blocks, respectively. If not considering results on biclique cryptanalysis,these are currently the best public results on this reduced version of the Piccolo block cipher.

With the expansion of wireless technology, vehicular ad-hoc networks(VANETs) are emerging as a promising approach for realizing smart cities and addressing many serious traffic problems, such as road safety, convenience, and efficiency. To avoid any possible rancorous attacks, employing lightweight ciphers is most effective for implementing encryption/decryption, message authentication, and digital signatures for the security of the VANETs. Light encryption device(LED) is a lightweight block cipher with two basic keysize variants: LED-64 and LED-128. Since its inception, many fault analysis techniques have focused on provoking faults in the last four rounds to derive the 64-bit and 128-bit secret keys. It is vital to investigate whether injecting faults into a prior round enables breakage of the LED. This study presents a novel impossible meet-in-the-middle fault analysis on a prior round. A detailed analysis of the expected number of faults is used to uniquely determine the secret key. It is based on the propagation of truncated differentials and is surprisingly reminiscent of the computation of the complexity of a rectangle attack. It shows that the impossible meet-in-the-middle fault analysis could successfully break the LED by fault injections.

C5 olefin separation is of great importance and challenge in industry with the increasing demand for synthetic rubber.However,the related study is limited due to the complex compositions and the similar boiling points.Here,we for the first time employ two anionpillared hybrid porous materials(ZU-62 and TIFSIX-2-Cu-i)towards the challenging separation of C5 olefin mixtures(trans-2-pentene,1-pentene and isoprene).These two adsorbents not only exhibit the unprecedented separation performance,but also show excellent recycle performance.Owing to the favorable electrostatic environment within a suitable confined space,TIFSIX-2-Cu-i is able to distinguish the three C5 olefins(frans-2-pentene,1-pentene and isoprene)with a high uptake of trans-2-pentene(3.1mmgol·g^(-1))ZU-62(also termed as NbOFFIVE-2-Cu-i)with contracted aperture size shows exclusion effect to the relatively large molecule of isoprene at low pressure range(0-6 kPa),contributing to the excellent separation selectivity of 1-pentene/isoprene(300).The excellent separation performance of ZU-62 and TIFSIX-2-Cu-i is verified by the breakthrough experiment.And interestingly,the regeneration tests show that C5 olefins can be easily desorbed from ZU-62,TIFSIX-2-Cu-i under 298 K.Moreover,the detailed adsorption behavior is further revealed by simulation studies.

The tree ring has been regarded as an emerging archive to reconstruct historical atmospheric mercury(Hg)trends,but with the large knowledge gaps in the reliability.In this study,we comprehensively evaluated the Hg source,radial translocation and age effect of Masson pine(Pinus massoniana)tree ring at Mt.Jinyun in Chongqing,to assess the suitability of such tree ring as the archive of atmospheric Hg.Results showed that distinct variabilities among Masson pine tree-ring Hg concentration profiles.The Hg concentration significantly increased along with stem height(P<0.05),indicating the Hg in tree rings mainly derived from foliage uptake atmospheric Hg.We found a distinct age effect that the tree ring of young trees had the higher Hg concentration.Besides,we used the advection-diffusion model to demonstrate how Hg concentration shifted by the advection or/and diffusion in tree rings.The modeling results showed that the advection induced radial translocation during the young growth period of tree was a plausible mechanism to result in the tree-ring Hg record largely different from the trend of anthropogenic Hg emissions in Chongqing.We finally suggest that in further Hg dendrochemistry,better discarding the tree-ring Hg profile of the young growth period to reduce impacts of the radial translocation and age effect.
