Silk-crosslinked polyester fibrous air filters with electrostatic interfacial mediation for high- efficiency and low-resistance air purification
, Device, Vol: 2Similar to most air filtration strategies, fibrous filters have the trade-off between efficiency and air flow. An electrostatic-assisted electret filter may help improve filtration efficiency while maintaining air flow. In this work, we present a silk-nanofiber-modified polyethylene terephthalate (SNF@PET) fiber filter with an improved compression strength and modulus by 1.9 and 1.6 times respectively, at 2 wt % SNF content, increasing the structural stability of the filter to support a higher air flow. The filtration efficiencies of the SNF@PET fiber membrane for PM<inf>0.3-0.5</inf> and PM<inf>0.5-1</inf> are up to 99.7% and 99.6%, respectively, with a corresponding pressure drop of 3.3 Pa at 0.1 m s<sup>−1</sup> air velocity. The SNF@PET fiber filter showed a slight decrease in filtration efficiency to 98.3% for PM<inf>0.3-0.5</inf> and a small increase of pressure drop to 3.7 Pa (from 3.3 Pa) after 400 h.

A novel temporal mixed-integer market penetration model for cost-effective uptake of electric boilers in the UK chemical industry
, Journal of Cleaner Production, Vol: 446, ISSN: 0959-6526The UK chemical industry is the largest consumer of natural gas for process heating and power generation, with an annual consumption of 26.3 TWh. Reduction in natural gas consumption and associated carbon emissions can be achieved through electrification of heat. However, the adoption of electric boilers is lethargic due to economic barriers. Hence, market-based policy interventions are required. This study aims to accelerate the adoption of electric boilers in the UK's chemical industry, aligning with the UK's ambitious 2035 industrial decarbonisation goals while considering economic impacts, by designing market-based policy interventions and comparing two adoption patterns. A novel multi-period Mixed-Integer Market Penetration Optimisation Model is developed and applied to inform decisions about transitioning from natural gas to electric boilers. The model is applied to a case study of all the heating systems (490 boilers) in the UK chemical industry from 1 MW to 60 MW boilers. Results show that effectively implementing a gas tax, electricity subsidy, annual grant and carbon tax can generate sufficient demand-pull to reduce the cost of electric boilers from 30 to 85 % depending on the boiler size. A carbon tax starting at £280 per tCO2e and reducing to £170 per tCO2e coupled with electricity subsidies is essential for this transition. The policies are designed such that a win-win is achieved between government and industry; specifically, revenue from the carbon tax and gas tax is used to support the grant and electricity subsidy thereby achieving cost neutrality for government. At 100 % uptake of electric boilers in 2033, the total carbon emissions reduce by 89 %, which is above the 2035 UK industry goal of 60 % reduction. The research establishes a robust policy timeline that can drive industrial electrification in the UK's chemical sector. It highlights the need for a multi-faceted approach, incorporating various policy instruments to overcome the ba

Revisiting “quantity” and “quality” of science from young scholars
, Matter, Vol: 7, Pages: 715-717, ISSN: 2590-2393Excessive attention has been paid to the quantity of research, with scientific institutions emphasizing metrics such as h-index, impact factors of journals, and the number of publications. Increasingly, researchers become superficial, impetuous, and fanatical in the quest for quantity rather than focusing on quality and making a real impact. In this paper, we call for revitalizing a rational and impartial attitude toward quantity and scientific impact.

Critical review on mobile direct air capture: Concept expansion, characteristic description, and performance evaluation
, Matter, Vol: 7, Pages: 889-933, ISSN: 2590-2393The widespread adoption of direct air capture (DAC) is necessary for achieving net-zero emissions by 2050. However, on-site DAC development faces challenges like inconsistent technical solutions and significant initial investment. The proposal of mobile DAC offers an alternative technical route to scaling up DAC through distributed deployment, introducing a brand-new application scenario. Two types of mobile DAC are concerned, including integrating DAC with the existing transportation equipment and specialized mobile DAC devices for sniffing and capturing CO<inf>2</inf>. The detailed discussions cover the fundamental operation strategies and performance evaluation. Firstly, the mobile DAC in vehicles and ships is reviewed, focusing on integrating conventional DAC systems with common transportation. Then, the specialized devices for CO<inf>2</inf> sniffing and capturing, i.e., mobile DAC in low- and high-altitude aircraft, are proposed. This review envisions a future where mobile DAC technology is widely deployed in various human activity spaces, serving as a standard negative-emission solution.

What do the UK public think about the co-benefits that climate action can bring?
This slide deck summarises findings from a nationally representative sample (on the basis of age, gender and ethnicity) of 1,021 people who were asked to share their opinions about the co-benefits of climate action. People were surveyed via the online survey platform Prolific on Monday 12th February 2024. The headline findings and recommendations are followed by a case study focused on homes that are more affordable to heat. The insights in this slide deck build on findings from a Grantham report published in October 2023, How do UK citizens perceive the co-benefits of climate action? which included survey and focus groups with members of the UK public.

Data-driven energy efficient speed planning for battery electric industrial vehicles: Forklift as a case study
, Journal of Cleaner Production, Vol: 443, ISSN: 0959-6526Battery electric industrial vehicles (BEIVs) offer significant environmental protection and decarbonization potential for rapidly growing logistics and transportation sectors in China. However, the limited driving range remains a major obstacle to the widespread adoption of BEIVs. Eco-driving is an effective solution that can improve energy efficiency and extend the driving range of vehicles by controlling driving behavior and speed. Therefore, this paper introduces an energy efficient speed planning method for BEIVs, in which data-driven models are developed to estimate energy consumption. Real-world driving data collected from a BEIV are used to model the energy consumption by curve fitting, random forest, and LSTM. The speed planning process is considered a Markov Decision Process, which is solved using Dynamic Programming and Q-learning, respectively. The case study of a battery electric forklift shows that speed planning can reduce energy consumption by 13%–27% compared to time-optimal speed, while only increasing the driving time by 10%–20%.

Impact of precipitation on ocean responses during a tropical cyclone
, Journal of Physical Oceanography, Vol: 54, Pages: 895-909, ISSN: 0022-3670Precipitation plays a crucial role in modulating upper-ocean salinity and the formation of the barrier layer, which affects the development of tropical cyclones (TCs). This study performed idealized simulations to investigate the influence of precipitation on the upper ocean. Precipitation acts to suppress the wind-induced sea surface reduction and generates an asymmetric warming response with a rightward bias. There is substantial vertical change with a cooling anomaly in the subsurface, which is about 3 times larger than the surface warming. The mean tropical cyclone heat potential is locally increased, but the net effect across the cyclone footprint is small. The impact of precipitation on the ocean tends to saturate for extreme precipitation, suggesting a nonlinear feedback. A prevailing driver of the model behavior is that the freshwater flux from precipitation strengthens the stratification and increases current shear in the upper ocean, trapping more kinetic energy in the surface layer and subsequently weakening near-inertial waves in the deep ocean. This study highlights the competing roles of TC precipitation and wind. Because the TC category is weaker than category 3, the warming anomaly is caused by reduced vertical mixing, whereas for stronger storms, the advection process is most important.
