Abstract. Future trends in air pollution and greenhouse gas (GHG) emissions for China are of great concern to the community. A set global scenarios regarding future socio-economic climate developments, combining shared pathways (SSPs) with forcing outcomes as described by Representative Concentration Pathways (RCPs), was created Intergovernmental Panel on Climate Change (IPCC). Chinese researchers have also developed various emission considering detailed local environmental policies....
As the largest energy infrastructure in China, power sector consumed approximately half of China's coal over past decade and threatened air quality greenhouse gas (GHG) abatement targets. In this work, we assessed evolution coal-fired plants associated emissions China during 2010-2030 by using a unit-based emission projection model, which integrated historical plant information, turnover future fleet, end-of-pipe control technologies. We found that, driven stringent environmental...
Additive manufacturing has received attention for the fabrication of medical implants that have customized and complicated structures. Biodegradable Zn metals are revolutionary materials orthopedic implants. In this study, pure porous scaffolds with diamond structures were fabricated using laser powder bed fusion (L-PBF) technology. First, mechanical properties, corrosion behavior, biocompatibility characterized in vitro. The then implanted into rabbit femur critical-size bone defect model...
Abstract Architected materials that consist of multiple subelements arranged in particular orders can demonstrate a much broader range properties than their constituent materials. However, the rational design these generally relies on experts’ prior knowledge and requires painstaking effort. Here, we present data-efficient method for high-dimensional multi-property optimization 3D-printed architected utilizing machine learning (ML) cycle consisting finite element (FEM) 3D neural networks....
Abstract Reconciling the dilemma between rapid degradation and overdose toxicity is challenging in biodegradable materials when shifting from bulk to porous materials. Here, we achieve significant bone ingrowth into Zn-based scaffolds with 90% porosity via osteoinmunomodulation. At microscale, an alloy incorporating 0.8 wt% Li employed create a eutectoid lamellar structure featuring LiZn 4 Zn phases. This microstructure optimally balances high strength immunomodulation effects. mesoscale,...
The shape of atmospheric mineral particles 0.1–6 µm radius was studied by electron microscopy applied to the samples collected in three arid regions China (Qira Taklamakan Desert, Zhangye near southern border Badain‐Jaran Desert and Hohhot northern China). In all regions, showed irregular shapes with a median aspect ratio b/a (ratio longest dimension b orthogonal width ) 1.4. Although exhibited no clear size dependence, circularity factor (4π S/l ²; S is surface area l periphery length)...
Previous studies have associated ambient particulate chemical constituents with adverse cardiopulmonary health effects. However, specific pollution sources behind the effects of particles are uncertain. We examined fine (PM2.5) from different in Beijing, China, among a panel 40 healthy university students. Study subjects were repeatedly for series indicators during three 2-month-long study periods (suburban period, urban period 1, and 2) 2010-2011 before after relocating suburban campus to...
Elevated blood pressure (BP) has been associated with particulate matter (PM) air pollution, but associations PM chemical constituents are still uncertain.We investigated of BP various fine (PM2.5) during 460 repeated visits among a panel 39 university students.Resting was measured using standardized methods before and after the students relocated from suburban campus to an urban different pollution contents in Beijing, China. Air data were obtained central monitors close student residences....
Abstract Background Ambient air pollution has been associated with activation of systemic inflammation and hypercoagulability increased plasma homocysteine, but the chemical constituents behind association are not well understood. We examined relations various fine particles (PM 2.5 ) biomarkers inflammation, coagulation homocysteine in context traffic-related pollution. Methods A panel 40 healthy college students underwent biweekly blood collection for 12 times before after their relocation...
Zn is promising candidate material for biodegradable implants due to its acceptable biocompatibility and moderate degradation rate. However, the strength of pure metal regarded not enough. In this work, Zn-xWE43 porous scaffolds were fabricated by laser powder bed fusion (L-PBF) with different mass ratios WE43: 2%, 5% 8%. WE43 a Mg alloy addition Y rare earth elements, has been clinically verified. The formation quality, microstructure mechanical properties analyzed. L-PBF samples high...
Additive Manufacturing (AM) exhibits tremendous advantages in producing customized medical implants and has achieved successful clinical applications for non-degradable metals such as titanium, stainless steel cobalt alloys, particularly the form of porous scaffolds bone implants. Biodegradable materials allow metal to degrade while natural tissue grows thereby reducing implant lifetime within body a minimum. The design freedom AM especially Laser Powder Bed Fusion (LPBF) overcomes technical...
Postoperative anatomical reconstruction and prevention of local recurrence after tumor resection are two vital clinical challenges in osteosarcoma treatment. A three-dimensional (3D)-printed porous Ti6Al4V scaffold (3DTi) is an ideal material for reconstructing critical bone defects with numerous advantages over traditional implants, including a lower elasticity modulus, stronger bone-implant interlock, larger drug-loading space. Simvastatin multitarget drug anti-tumor osteogenic potential;...
Tropospheric ozone (O 3 ) enhancements have been continuously observed over Hong Kong. We studied the O enhancement events and assessed their relation to springtime maximum in lower troposphere Kong using a 6‐year (1993 1999) ozonesonde data set. identified source regions of biomass burning emission, established chemical transport characteristics ‐rich air masses enhanced profiles satellite imagery, trajectory trace gas measured on board DC‐8 aircraft during PEM‐West‐B experiment. total 39...
