Abstract
Purpose
The purpose of this paper is to focus on the way to achieve the sustainable development goals (SDGs). Through the introduction and learning of a specific case, this paper summarizes the specific process of green campus’s development and construction and directly discusses how to achieve the goal of sustainable development. By analyzing the achievements and measures of its construction, on the one hand, the experience and shortcomings of its green campus construction are summarized; on the other hand, the impact of Stanford’s own green campus construction on the local community is discussed.
Design/methodology/approach
This paper takes Stanford, one of the best green campuses assessed by sustainability tracking, assessment and rating system (STARS), as a case study in three steps. First, it introduces the academics, energy supply and demand, water and land, waste, management, food and living, buildings and transportation of its campus construction in detail; second, it uses the STARS to make a comprehensive sustainable evaluation of Stanford; finally, it discusses the development relationship between Stanford and local community.
Findings
The four characteristics of its green campus development model are summarized, namely, based on its own scientific research; from the aspect of environmental friendliness; to achieve joint participation; and forming complementary development with the community. The construction of green campus has changed from a single triangle framework composed of SDGs, STARS and universities to a compound triangle framework composed of SDGs, universities and communities on the existing basis, greatly expanding the way to realize SDGs.
Practical implications
This development mode will have direct guiding significance for the sustainable construction of other campuses.
Social implications
This paper also discusses the development concept from green campus to sustainable community to provide positive reference to achieve the global SDGs from the perspective of colleges and universities.
Originality/value
According to the historical track of its development, this paper combines the two (SDGs and green campus) to discuss by using campus construction as an effective way to achieve the SDGs. On the basis of literature research and case study, STARS sustainable assessment is introduced. This will lead to quantitative analysis of sustainable construction in the discussion of the specific case, judging the specific sustainable degree of all aspects of campus construction, to provide a scientific basis for summarizing its characteristics of development mode.

Abstract
Purpose
This study aims to establish a multi-physics-coupled model for an electrostatic particulate matter (PM) sensor. The focus lies on investigating the deposition patterns of particles within the sensor and the variation in the regeneration temperature field.
Design/methodology/approach
Computational simulations were initially conducted to analyse the distribution of particles under different temperature and airflow conditions. The study investigates how particles deposit within the sensor and explores methods to expedite the combustion of deposited particles for subsequent measurements.
Findings
The results indicate that a significant portion of the particles, approximately 61.8% of the total deposited particles, accumulates on the inside of the protective cover. To facilitate rapid combustion of these deposited particles, a ceramic heater was embedded within the metal shielding layer and tightly integrated with the high-voltage electrode. Silicon nitride ceramic, selected for its high strength, elevated temperature stability and excellent thermal conductivity, enables a relatively fast heating rate, ensuring a uniform temperature field distribution. Applying 27 W power to the silicon nitride heater rapidly raises the gas flow region's temperature within the sensor head to achieve a high-temperature regeneration state. Computational results demonstrate that within 200 s of heater operation, the sensor's internal temperature can exceed 600 °C, effectively ensuring thorough combustion of the deposited particles.
Originality/value
This study presents a novel approach to address the challenges associated with particle deposition in electrostatic PM sensors. By integrating a ceramic heater with specific material properties, the study proposes an effective method to expedite particle combustion for enhanced sensor performance.
