A zero-gap cell with porous electrodes is a promising configuration for alkaline waterelectrolysis. However, gas evacuation becomes a challenge in that case, as bubbles can
get trapped within the electrode’s 3-D structure. We have recently investigated anumber of 3-D electrode geometries, including Ni-based foams and 3-D printed
structures, in order to address the issue of gas evacuation. By a combined experimental
and modelling approach, our work allowed to identify the structural parameters that
direct the performance of 3-D structured geometries toward enhanced gas evacuation.
It appears that efforts in optimizing the electrode’s geometry can give a similarelectrochemical performance enhancement as optimizing its electro-catalytic
composition.

ABSTRACT

Forced planarization by covalently fastening adjacent aromatic units in the
conjugated backbone strengthens the parallel p-orbital interactions to elongate
effective conjugation length and facilitate electron delocalization, providing aneffective way to reduce the band gap and enhances the intrinsic charge mobility.
In this talk, I will present our recent development of various multifused laddertype structures with tunable properties and functions. Ladder-type building
blocks can be further end-capped with two acceptors to form a new class of ntype nonfullerene acceptors to achieve high power conversion efficiencies oforganic photovoltaics.

Intramolecular and intermolecular interactions play a pivotal role in determine the structureand function of biomolecules, including processes such as protein (un)folding, protein-protein
and protein-DNA interactions. In this lecture, I will introduce a powerful single-molecule tool,
atomic force microscopy-based force spectroscopy, capable of manipulating biomolecules andquantify corresponding biomolecular interactions. We develop a site-specific protein
immobilization approach by integrating enzymatic ligation and click reaction, thereby
enabling accurate and efficient single-molecule measurement. Then, we measured a wide
range of metal-ligand bond strength in protein upon mechanical unfolding. Moreover, we
explore the binding between SARS-CoV-2 spike protein and its receptor human ACE2 protein,
shedding light on the functional implications of the prevalent N501Y mutation in the virus.
Measurement of other interactions by AFM will also be mentioned.

Mechanochemical polymer synthesis is an emerging area, broadening
the realm of polymer science. Our research group has been involved inball-milling polymer synthesis since 2016. We witness that manysolution-based polymerizations can be transferred to solvent-free solidstate conditions, promoting green chemistry. Also, the impossiblecombinations in the solution are possible in mechanochemical
conditions. In addition, we recently discovered the simplest
depolymerization system of polyesters and polycarbonates using
mechanochemistry. The case-by-case presentation will explain why
mechanochemical polymer synthesis is an attractive field.

Due to the fast development of consumer electronics and wearable devices, demand
for safe and light batteries is soaring. Flexible zinc-air batteries (FZABs) using quasisolid gel polymer electrolytes (GPEs) are considered a potential candidate because of
their high energy density, long-term durability and safety. In the first part, a simple
method for preparing GPEs is reported to maintain a high water content within the gel,which is the key factor facilitating the high discharge rate of FZABs. Here the spinel
NiCo2O4 is employed as the bifunctional catalyst for fabricating FZABs.
Electrochemical measurements indicate a good bifunctionality for both the ORR andOER. In the second part of this contribution, a PVA-based GPE with a high watercontent (70%) and a bifunctional catalyst, Ru0.6Sn0.4O2, are employed to fabricate the
FZAB using the neutral electrolytes. In addition, the electrolyte formulations are
systematically investigated in order to get improved zinc air battery performance.

Catalysis plays a pivotal role in all chemical strategies towards novel more
efficient and sustainable chemical conversion processes for thevalorization of renewable feedstocks such as biomass and CO2.
Traditionally, catalyst development has predominantly relied on trial-anderror approaches. The grand challenge in the field is to make a step
towards the rational design of efficient catalysts for a given chemical
reaction. This on one hand requires a deep insight into the active site
structure, the mechanism of their action, and evolution under operating
conditions This seminar is focused on recent efforts in the computational
catalysis methodologies to resolve active site structures and get an insight
into the challenging and rare-event chemistry of the catalysis.

Abstract: Organic semiconductors have attracted much attention for their potential applications
and commercial products such as organic light-emitting diode displays, organic field effecttransistors (OFETs)-based active matrix display, and organic-based radio frequency identification(RFID) tags, Among these, solution-processable small molecules with high performance andambient stability are of great interest due to their possibility of a low-cost solution process andhigh flexibility in molecular design/modification for various electronic/thermoelectric applications.
In my talk, we outline the design strategies which aim to develop high performing organic
semiconductor materials in the fields of OFETs and organic thermoelectrics (OTEs), a series ofsolution-processed thiophene-based small molecules are reported and these results indicate that
OFETs semiconducting materials can be modulated through successive changes in conjugation
length/side chain substituent length and molecular interaction, based on a combination ofmolecular design and solution-processing technique. OTEs materials can directly transform thewaste heat into the electrical power without causing any pollution but their development is limited
due to the poor performance especially low conductivity. Doping organic semiconductors andconjugated polymer composites are used for achieving the enhanced performance, and flexible
thermoelectric generator based on these materials can be fabricated.

including the activation of methane and the formation of methylidenes,
and dehydrocoupling will be also addressed. In the last component, I
will introduce the use of organometallic Ir catalysts for themonoborylation of methane and how one can improve catalytic
turnover by immobilizing the homogeneous Ir(I) fragment onto
amorphous silica.

₇ 㢟㸸Smart Cell Factory Design for Muconate

and Shikimate in Escherichia coliㅮ ᖌ㸸 Prof. Eung-Soo Kim

3-Dehydroshikimate (DHS) is a useful starting metabolite for the biosynthesisof muconic acid (MA) and shikimic acid (SA), which are precursors of various valuable
polymers and drugs. Here, we created an engineered Escherichia coli cell factory to
produce a high titer of DHS as well as an efficient system for the conversion DHS into
MA. First, the genes showing negative effects on DHS accumulation in E. coli were
disrupted. In addition, the genes involved in DHS biosynthesis were overexpressed toincrease the glucose uptake and flux of intermediates. The redesigned DHSoverproducing E. coli strain grown in an optimized medium produced approximately
117 g/L DHS in 7-L fed-batch fermentation, which is the highest level of DHS production
demonstrated in E. coli.
To accomplish the DHS-to-MA conversion, which is originally absent in E. coli,a codon-optimized heterologous gene cassette was expressed as a single operon
under a strong promoter in a DHS-overproducing E. coli strain. This redesigned E. coli
grown in an optimized medium produced about 64.5 g/L MA in 7-L fed-batch
fermentation. Similarly, the rationally designed shikimate-overproducing E. coli strain
grown in an optimized medium also produced approximately 101 g/L of shikimate in 7L fed-batch fermentation, which is the highest level of shikimate production reported
thus far. Overall, rational cell factory design and culture process optimization for
microbial-based shikimate production will play a key role in complementing traditional
plant-derived shikimate production processes.

Employing mechanical force in organic transformations is nothing new;instead, this crude approach has been considered one of the oldest
techniques in synthetic chemistry. Recently, mechanochemistry has
made a comeback due to the increased interest in developing moresustainable ways of doing chemistry. Despite that, most ball-millingexamples emphasize the rate-acceleration aspect. The unique selectivity
and mechanical force-specific reactivity aspect are much less discussed.
In this talk, I will discuss our recent progress in the area of coordination
self-assembly and radical chemistry by employing mechanochemical
approaches to carry out “moving uphill reactions” that are difficult withtraditional solution-based reaction settings.
