Crimean-Congo hemorrhagic fever(CCHF)is a zoonotic disease caused by the CCHF virus(CCHFV),which is primarily transmitted by ticks(Lorenzo Juanes et al.2023).It is an emerging disease that occurs sporadically in Africa,Asia,and Europe,with a high morbidity and mortality rate,as high as 30%in humans(Ceylan et al.2013).CCHFV,belonging to genus Nairovirus,family Bunyaviridae,was first identified in the Congo in the 1960s.

A new syntactic foam material was prepared by screening three different average particle sizes of cenospheres(150,200,and 300μm)from industrial waste fly ash.Axial impact testing on syntactic foam filler and foam-filled tubes was conducted using a drop hammer test machine.The effects of parameters,such as the size of cenospheres and the impact velocity,on the mechanism of deformation,mechanical characteristics,and capacity for energy absorption of the specimen were investigated.On this basis,the differences in compressive properties exhibited by the syntactic foam-filled tubes under the two loading conditions were investigated.The results indicate that with the decrease in the average diameter of cenospheres,the initial peak crushing load and mean crushing load of foam-filled tubes increase,while the compression efficiency decreases.The specific energy absorption(SEA)of the syntactic foam-filled tube can reach 25 J/g.With the increase of impact velocity,the SEA of the specimen increases slightly.It was demonstrated that the syntactic foam-filled tube exhibits a higher effective energy absorption ratio under impact loading compared to quasi-static loading.

Wood-based bilayer solar evaporators,which possess cooperative advantages of natural wood and photothermal conversion coating including fast water transportation,low heat conduction,renewability,and high light absorbability,hold great promise for water purification.However,previous studies suffer from low evaporation rates and high cost of coatings,and lack a deep understanding how the porous structures of coating layer function.Herein,a novel bilayer solar evaporator is designed through facile surface coating of wood by low-cost porous carbon from controlled carbonization of polyester waste.The porous carbon bears rich oxygen-containing groups,well-controlled micro-/meso-/macropores,and high surface areas(1164 m^(2) g^(−1)).It is proved that porous carbon improves sunlight absorption and promotes the formation of numerous water clusters to reduce water evaporation enthalpy.Owing to these combined features,the bilayer solar evaporator exhibits high evaporation rate(2.38 kg m^(−2) h^(−1)),excellent longterm stability,and good salt resistance.More importantly,a large-scale solar desalination device for outdoor experiments is developed to produce freshwater from seawater.The daily freshwater production amount(3.65 kg m^(−2))per unit area meets the daily water consumption requirement of one adult.These findings will inspire new paradigms toward developing efficient solar steaming technologies for desalination to address global freshwater shortage.

This study investigated the factors that are associated with sleep disturbances among Chinese athletes.Sleep quality and associated factors were assessed by the Athlete Sleep Screening Questionnaire(ASSQ,n?394,aged 18–32 years,47.6%female).Sleep difficulty score(SDS)and level of sleep problem(none,mild,moderate,or severe)were used to classify participants'sleep quality.Categorical variables were analyzed by Chi-square or fisher's exact tests.An ordinal logistic regression analysis was used to explore factors with poor sleep(SDS8).Approximately 14.2%of participants had moderate to severe sleep problem(SDS8).Fifty-nine percent of the athletes reported sleep disturbance during travel,while 43.3%experienced daytime dysfunction when travelling for competition.No significant difference was found in the SDS category between gender,sports level and events.Athletes with evening chronotype were more likely to report worse sleep than athletes with morning and intermediate chronotype(OR,2.25;95%CI,1.44–3.52;p<0.001).For each additional year of age,there was an increase of odds ratio for poor sleep quality(OR,1.15;95%CI,1.04–1.26;p?0.004),while each additional year of training reduced the odds ratio(OR,0.95;95%CI,0.91–0.99;p?0.044).To improve sleep health in athletes,chronotype,travel-related issues,age and years of training should be taken into consideration.

Sustainable conversion of waste plastics into valuable carbon materials for diverse applications provides a promising strategy to dispose the municipal and industrial waste plastics.However,it remains a challenge to precisely control the crosslinking reaction for transforming waste polyesters into N-doped porous carbon (NPC) with well-defined microstructures.Herein,we put forwards a strategy of stepwise crosslinking using melamine and ZnCl_(2)/NaCl eutectic salts to convert poly (ethylene terephthalate)(PET) into NPC at 550℃.We prove that firstly melamine reacts with PET degradation products to form a crosslinking structure,and subsequently ZnCl_(2)/NaCl promote the dehydration and decarboxylation of the crosslinking structure to generate a more thermally stable crosslinking structure.The coordination of two tandem crosslinking reactions is critical to control the microstructure of NPC.Without activations,NPC shows large specific surface area of 1173 m~2g^(-1),abundant N dopants,and rich oxygen-containing groups.These combined features endure NPC with excellent performance in CO_(2) capture and solar steam generation,e.g.,high CO_(2) adsorption capacity of 6.47 mmol g^(-1) and evaporation rate of 1.62 kg m^(-2)h^(-1).More importantly,NPC is compared to or prevails over previous carbon-based CO_(2) adsorbents or photothermal materials.This work will advance the research on “green” reutilization of low-cost polyester wastes to prepare sustainable carbon for solar energy conversion,environmental protection,etc.

Over recent decades, advancements in complementary metal-oxide-semiconductor integrated circuits(ICs)have mainly relied on structural innovations in transistors. From planar transistors to the fin field-effect transistor(FinFET) and gate-all-around FET(GAAFET), more gate electrodes have been added to three-dimensional(3D) channels with enhanced control and carrier conductance to provide higher electrostatic integrity and higher operating currents within the same device footprint. Beyond the 1-nm node, Moore's law scaling is no longer expected to be applicable to geometrical shrinkage. Vertical transistor stacking, e.g. in complementary FETs(CFET), 3D stack(3DS) FETs and vertical-channel transistors(VFET), for enhanced density and variable circuit or system design represents a revolutionary scaling approach for sustained IC development. Herein, innovative works on specific structures, key process breakthroughs, shrinking cell sizes and design methodologies for transistor structure research and development are reviewed. Perspectives on future innovations in advanced transistors with new channel materials and operating theories are also discussed.

Currently,the microwave absorbers usually suffer dreadful electromagnetic wave absorption(EMWA)performance damping at elevated temperature due to impedance mismatching induced by increased conduction loss.Consequently,the development of high-performance EMWA materials with good impedance matching and strong loss ability in wide temperature spectrum has emerged as a top priority.Herein,due to the high melting point,good electrical conductivity,excellent environmental stability,EM coupling effect,and abundant interfaces of titanium nitride(TiN)nanotubes,they were designed based on the controlling kinetic diffusion procedure and Ostwald ripening process.Benefiting from boosted heterogeneous interfaces between TiN nanotubes and polydimethylsiloxane(PDMS),enhanced polarization loss relaxations were created,which could not only improve the depletion efficiency of EMWA,but also contribute to the optimized impedance matching at elevated temperature.Therefore,the TiN nanotubes/PDMS composite showed excellent EMWA performances at varied temperature(298-573 K),while achieved an effective absorption bandwidth(EAB)value of 3.23 GHz and a minimum reflection loss(RLmin)value of−44.15 dB at 423 K.This study not only clarifies the relationship between dielectric loss capacity(conduction loss and polarization loss)and temperature,but also breaks new ground for EM absorbers in wide temperature spectrum based on interface engineering.
