Reference excerpt

Sihai Yang is a professor in the College of Chemical and Molecular Engineering at Peking University. His research in general is based on Inorganic and Materials Chemistry where he and his group investigate on the design and synthesis of novel Metal Organic Frameworks (MOFs) and zeolites for potential applications in gas adsorption, catalysis and industrial separations.

Education Sihai Yang completed his Bachelor of Science at Peking University in 2007 and his Doctor of Philosophy degree at University of Nottingham in 2011.

Research and career After graduating, Yang received an EPSRC PhD+ Fellowship, an Early Career Leverhulme Trust Fellowship in 2011 at The University of Nottingham. He later received the Nottingham Research Fellowship in 2013 and in 2015 moved to The University of Manchester where he currently is at the position of Professor. He develops solid materials for applications in clean-air technology, catalysis, biomass conversion, energy storage, separation and conductivity. His team studies a wide range of porous materials based upon metal-organic frameworks, zeolites, and inorganic materials. The key research interest is to investigate the chemical processes involved in host-guest binding underpinning their materials property using state-of-the-art structural and dynamic studies by synchrotron X-ray diffraction, spectroscopy and neutron scattering, combined with modelling. Porous materials containing nanosized cavities (1-20 nm), the walls of which are decorated with designed active sites, can form unique functional platforms to study and re-define the chemistry and reactivity of small molecules within the confined space. Research in his group involves design, synthesis and characterisation of the materials, and more importantly, the structural and dynamic studies at National Facilities to understand their materials function at a molecular level. Recent finding includes the discovery of catalytic origins for a range of important biomass conversions, and a series of new metal-organic frameworks showing emerging properties for the clean-up of air pollutants, such as SO2 and NOx.

Notable work In 2018, Yang led a research with Martin Schröder where they designed a novel robust Metal Organic Framework (MFM - 300(Al)) which exhibited reversible NO2 isotherm uptake of 14.1 mmol g−1 and also showed the capability to selectively remove low concentrations of NO2 (5,000 to < 1 ppm) from gaseous mixtures. The research revealed five types of supramolecular interactions that cooperatively binds both NO2 and N2O4 molecules within the MFM-300(Al) framework and also showed the coexistence of helical monomer–dimer chains of NO2 within the framework which provided an initial understanding of the behavior of guest molecules within porous hosts which may provide further development routes of future NO2 capture and conversion technologies. In 2019, Yang led a further research with Martin Schröder where a novel Metal Organic Framework (MFM - 520) was synthesized which showcased a high adsorption capacity of NO2 (4.2 mmol g−1). The framework also showed a high turn over number and treatment of captured NO2 in the framework with water led to a quantitative conversion of the captured NO2 into HNO3 which is an important feedstock for fertilizer production.

Worked examples

Example 1 — a first encounter with Sihai Yang

Start with the simplest possible case. Write down what Sihai Yang claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Sihai Yang before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Sihai Yang ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Sihai Yang

In research: Sihai Yang appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Sihai Yang in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Sihai Yang is common in secondary-school and first-year university syllabi. It links to neighbouring topics 21st-century Chinese chemists, Alumni of the University of Nottingham, Chemists of the University of Manchester, so understanding it makes those chapters shorter.
In everyday life: Look for Sihai Yang outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
