НОВЫЕ РАДИОУГЛЕРОДНЫЕ ДАТЫ ПО СЯНЬБИЙСКОМУ ПЕРИОДУ
Authors: Самашев Зайнолла , Жунисханов Айдын Сенгалиевич 
Published: October 2021

Сяньби – полиэтническая общность, возникшая в начале І тыс. н.э. в пространствах Центральной Азии. Продвижение сяньбийцев на запад совпало с распадом империи хуннов в ІІІ в. н.э. Начиная с этого периода сяньбийцы стали расселяться на территории Восточного Казахстана и устанавливать свое политическое господство. Изучение археологических памятников сяньбийцев проводится систематично с 2016 г. За это время исследовано свыше 60 выкладок. Проблемы расселения и миграции сяньбийцев на территории современного Восточного Казахстана расмастривались в основном в рамках сравнительно-типологического анализа. В связи с этим огромное значение имеет получение и оперативное введение в научный оборот радиоуглеродных калиброванных дат, связанных с сяньбийским периодом. В данной статье впервые в научный оборот вводятся результаты радиоуглеродного анализа, полученного из остеологического материала присходящего из выкладки № 68 могильника Берел и впускного погребения царского кургана могильника Елекесазы. Радиоуглеродный анализ был выполнен в Государственном научно-исследовательском институте Центра физических и технологических наук г. Вильнюс (Литва) (ответственный за исследование Жилвинас Ежеринскис). В результате были получены новые данные о расселении сяньбийцев на территории Восточного Казахстана.

Background: There are shared guidelines about Non-Operative Management (NOM) of splenic injuries, but some unanswered questions remain. The aim of the present study is to establish the usefulness of a standardized protocol for management and follow-up of NOM patients with splenic injuries. Methods: Multicenter retrospective observational study including patients with major blunt trauma (ISS >15) with splenic injuries managed between January 1st 2014 and December 31st 2016 in two Italian I level Trauma Centers: one with a standardized management and follow-up protocol for NOM (Bufalini Hospital, Cesena, BH), and the other without it (ASST Papa Giovanni XXIII Hospital, Bergamo, PG23H). Comparison between patients’ outcomes were performed and a propensity score model was calculated. Results: 47 patients managed in BH and 49 patients in PG23H were included. In BH, a higher proportion of patients was treated with NOM (72.3 % vs. 53.1 %, p = 0.051). There was no difference in complication rate and mortality in patients treated with NOM in the two hospitals. A borderline significant trend to a higher NOM failure rate in PG23H was found (BH 0.0 % vs. PG23H 11.3 %, p = 0.076). The total splenic conservation rate was significantly higher in BH (BH 72.3 % vs. PG23H 46.9 %, p = 0.011). After the Propensity Score based matching, 72 patients were included and the total splenic conservation rate was significantly higher in BH (BH: 77.8 % vs. PG23H: 50.9 %, p = 0.014). Conclusions: The application of a protocol for in-hospital management and follow-up for NOM of patients with splenic injury could decrease the NOM failure rate and improve splenic conservation rate.

AbstractIntroductionLimited evidence exists showing the benefit of magnetic resonance (MR)‐only radiotherapy treatment planning for anal and rectal cancers. This study aims to assess the impact of MR‐only planning on target volumes (TVs) and treatment plan doses to organs at risks (OARs) for anal and rectal cancers versus a computed tomography (CT)‐only pathway.Materials and methodsForty‐six patients (29 rectum and 17 anus) undergoing preoperative or radical external beam radiotherapy received CT and T2 MR simulation. TV and OARs were delineated on CT and MR, and volumetric arc therapy treatment plans were optimized independently (53.2 Gy/28 fractions for anus, 45 Gy/25 fractions for rectum). Further treatment plans assessed gross tumor volume (GTV) dose escalation. Differences in TV volumes and OAR doses, in terms of Vx Gy (organ volume (%) receiving x dose (Gy)), were assessed.ResultsMR GTV and primary planning TV (PTV) volumes systematically reduced by 13 cc and 98 cc (anus) and 44 cc and 109 cc (rectum) respectively compared to CT volumes. Statistically significant OAR dose reductions versus CT were found for bladder and uterus (rectum) and bladder, penile bulb, and genitalia (anus). With GTV boosting, statistically significant dose reductions were found for sigmoid, small bowel, vagina, and penile bulb (rectum) and vagina (anus).ConclusionOur findings provide evidence that the introduction of MR (whether through MR‐only or CT‐MR pathways) to radiotherapy treatment planning for anal and rectal cancers has the potential to improve treatments. MR‐related OAR dose reductions may translate into less treatment‐related toxicity for patients or greater ability to dose escalate.

Published: October 2021

AbstractCatalytic synergy is an unresolved activity descriptor in energy conversion reactions. Here, this study reports the synergistically enhanced intrinsic oxygen evolution reaction activity of a FeNi model catalyst modified with molybdate oxo‐anions via concertedly boosted surface/interface interactions such as interfacial charge transfer, surface intermediate adsorption, in situ phase transformation, and gas bubble evolution. Capturing such cosynergistic impact reveals the accelerated transition of oxygen deprotonation to oxyhydroxide state, ready‐to‐function Fe and Ni active sites, the instant transformation of Fe and Ni local microenvironments to γ ‐FeOOH and β  ‐NiOOH phases, and ultrafast gas bubble growth and release. The accelerated oxygen bubble evolution dynamic is monitored in operando with a decreased dynamic variation of the interfacial Faradaic resistance. Such cosynergistic molybdate modification results in a tenfold increase in oxygen evolution turnover frequency as well as a 55 mV decrease in the overpotentials to deliver 10 and 1000 mA cm−2 with respect to the FeNi‐model catalyst.

AbstractElectrochemical carbon dioxide reduction reaction (CO2RR) is a promising approach to mitigate CO2 concentration and generate carbon feedstock. Recently, the (sub‐)nanometer design of catalyst structures has been revealed as an efficient means to control the reaction process through the local reaction environment. Herein, the synthesis of a novel tin oxide (SnOx) nanoparticle (NP) catalyst with highly controlled sub‐nanoscale interplanar gaps of widths <1 nm (SnOx NP‐s) is reported via the lithium electrochemical tuning (LiET) method. Transmission electron microscopy (TEM) and 3D‐tomo‐scanning TEM (STEM) analysis confirm the presence of a distinct segmentation pattern and the newly engineered interparticle confined space in the SnOx NP‐s. The catalyst exhibits a significant increase in CO2RR versus hydrogen evolution selectivity by a factor of ≈5 with 20% higher formate selectivity relative to pristine SnO2 NPs at −1.2 VRHE. Density functional theory calculations and cation‐size‐dependent experiments indicate that this is attributable to a gap‐stabilization of the rate‐limiting *OCHO and *COOH intermediates, the formation of which is driven by the interfacial electric field. Moreover, the SnOx NP‐s exhibits stable performance during CO2RR over 50 h. These results highlight the potential of controlled atomic spaces in directing electrochemical reaction selectivity and the design of highly optimized catalytic materials.

AbstractDesigning catalysts to accelerate the conversion of soluble lithium polysulfides (LiPSs) is regarded as a promising strategy to inhibit the shuttle effect, improving cathode performance of lithium–sulfur batteries (LSBs). Herein, a bifunctional Ni/Zn dual‐doped CoSe2 is designed to enhance the catalytic effect of CoSe2. Specifically, Ni functions better in catalyzing the conversion of LiPSs into Li2S with shorter CoS bond and longer SS bonds than Zn, while Zn demonstrates a better catalytic effect for Li2S decomposition with reduced Li2S decomposition barrier and elongated LiS bonds than Ni. Those endows Ni/Zn dual‐doped CoSe2 with bifunction in catalyzing conversion reaction of LiPSs and Li2S precipitation as well as the decomposition of Li2S, originating from the modified molecular structure of LiPSs and Li2S. As a result, the sulfur cathode with Ni0.1Zn0.1Co0.8Se2 achieves a rate capability of 681.74 mAh g–1 at 2C, and a cycling stability for 400 cycles with a decay rate of 0.065%. This work provides an effective way to improve catalytic effect of transition metal compounds for advanced LSBs by homogenous dual doping.

Published: October 2021

AbstractThe most emerging 2D‐materials‐based heterostructures are considered promising candidates because of their multifunctional logic applications for electric and optoelectronic devices. Here, a high gate tunable rectification in van der Waals heterostructure composed of n‐type rhenium disulfide (n‐ReS2) and p‐type germanium selenide (p‐GeSe), using pure Ohmic contacts, is reported. The large rectification ratio (RR) deprived of any Schottky contribution is tuned up to 4 × 105 because of the sharp interface of p‐GeSe and n‐ReS2. The sheet‐thickness effect over the rectification is also observed in the p‐GeSe/n‐ReS2 heterostructure as well. The profound photovoltaic measurements under lights of different power intensities depict a high photo responsivity of 3.9 × 103 A W−1 with an external quantum efficiency of 87% and specific detectivity (D* = 1.5 × 1012). The fast growth (16.6 µs) and decay times (12.3 µs) are extracted by the exponential rise and decay fitting. Moreover, practical applications of the p‐GeSe/n‐ReS2 heterostructure devices are exhibited by observing inverter behavior and high‐frequency switching operations, which is also the breakthrough of this research. Fabrication of such smart devices based on transition metal dichalcogenides (TMDs) van der Waals heterostructures may enhance the energy harvesting as well as the multifunctional logic switches.

AbstractCellulose exhibits outstanding chemical stability, nontoxicity, and renewable ability and is regarded as a candidate for next‐generation sustainable materials. After the nanofibrillation of cellulose, cellulose nanofiber (CNF) exhibits unique optical properties, good mechanical strength, and a high aspect ratio. It is suitable to be a matrix for the photocatalysts immobilization and applied in pollutant removal owing to its solvent resistance. Combined with 1D TiO2, the network structure may be expected and beneficial for the charge transport of TiO2 nanofibers. In this study, the flexible CNF composites film incorporated with various sizes and morphology of TiO2 photocatalysts is fabricated. The relationship between the chemical and physical properties of the composite film and morphological features are discussed. The GIWAXS analysis shows that the entanglement of self‐precipitated Ag‐doped TiO2 NFs (STNFs) and CNF induce the densely hierarchical stack and regular stacking orientation. For 30 day solvent resistance tests, various CNF composite films show outstanding stability in the acetone and dimethylformamide (DMF). In the photodegradation of methyl orange in ethanol, STNF/CNF film presents a high degradation efficiency of 87% and shows excellent stability of morphology and activity after three cycles. For volatile organic compound degradation, the degradation efficiencies toward methanol and DMF vapor are higher than 90%.

Published: October 2021

AbstractLithium metal anodes (LMAs) are the most promising candidates for high‐energy‐density batteries due to the high theoretical specific capacity and lowest potential. However, the practical application of LMAs is hampered by the short lifespan and unsatisfactory lithium utilization (<50%). An oxide–oxide heterojunction enhanced with nanochamber structure design is proposed to improve lithium utilization and cycling performance of LMA under ultrahigh rates. Typically, a MnO2–ZnO heterojunction provides high binding energy for strong absorption of Li‐ions and intimately bonded interfaces for fast transfer of electrons. Under the guidance of the smooth Li‐ion migration and rapid electron flow, the Li metal can be restricted as thin layers within submicro scale in nanochambers with constrain boundary and stress dissipation, inhibiting the local agglomeration and blocking. Thus, the lithiophilic active sites can be effectively exposed to the Li‐ions within submicro scale, improving the reversible conversion for high lithium utilization during long‐term cycling. As such, the Li@MnZnO/CNF electrode achieves a high lithium utilization of 70% at a record‐high current density of 50 mA cm−2 with areal capacity of 10 mAh cm−2. This work offers an avenue to improve lithium utilization for long‐lifespan LMAs working under high current densities and capacities.

Published: October 2021

AbstractSingle‐walled carbon nanotubes (SWCNTs) have been considered as one of the most promising electronic materials for the next‐generation electronics in the more Moore era. Sub‐10 nm SWCNT‐field effect transistors (FETs) have been realized with several performances exceeding those of Si‐based FETs at the same feature size. Several industrial initiatives have attempted to implement SWCNT electronics in integrated circuit (IC) chips. Here, the recent advances in SWCNT electronics are reviewed from in‐depth understanding of the fundamental electronic structures, the carrier transport mechanisms, and the metal/SWCNT contact properties. In particular, the subthreshold switching properties are highlighted for low‐power, energy‐efficient device operations. State‐of‐the‐art low‐power SWCNT‐based electronics and the key strategies to realize low‐voltage and low‐power operations are outlined. Finally, the essential challenges and prospects from the material preparation, device fabrication, and large‐scale ICs integration for future SWCNT‐based electronics are foregrounded.

AbstractIndividualized chemotherapy, which is at the forefront of acute myeloid leukemia (AML) treatment, has moderately improved outcomes over the past decade. Monitoring the peripheral blood blast burden during induction by flow cytometry has shown significant value in the evaluation of treatment responses. Our previous study reported the day 5 peripheral blast clearance rate (D5‐PBCR) as an indicator of early treatment response, and D5‐PBCR (+) patients showed poor outcomes. We performed the present phase 2 trial of early intervention in D5‐PBCR (+) patients with homoharringtonine (HHT) introduced in the traditional induction regimen with anthracycline and cytarabine. The primary endpoint was complete remission (CR). This study enrolled 151 patients, 65 patients were D5‐PBCR (+) and 55 patients completed induction with HHT addition. The overall CR rate after one course of induction was 84.4%, with 87.5% and 80.0% for the D5‐PBCR (−) and D5‐PBCR (+) groups, respectively. The incidence of grade 3/4 adverse events was comparable between the two groups. At the median follow‐up of 53.1 months, median overall survival (OS) was not reached in the entire cohort, and median event‐free survival (EFS) was 42.2 months. Neither the OS nor EFS showed significant differences between the D5‐PBCR (−) and D5‐PBCR (+) groups. Compared to historical data, significant improvements in both OS (p = .020) and EFS (p = .020) were observed in the D5‐PBCR (+) group. In conclusion, optimization of induction chemotherapy with idarubicin and cytarabine according to D5‐PBCR is feasible in patients with newly diagnosed AML. The addition of HHT demonstrated a good efficacy and safety profile.
