Highly effective fractionation chemistry to overcome the recalcitrance of softwood lignocellulose
Carbohydrate Polymers, 2023 The efficient fractionation and thus production of individual biomass components are pivotal processes in the biorefinery concept. However, the recalcitrant nature of lignocellulose biomass, especially in the case of softwood, is one of the main obstacles to the wider application of biomass-based chemicals and materials.

Introduction to the chemistry of fractionally charged atoms: Electronegativity [PDF]
Physical Review D, 1983 The behavior of massive fractionally charged particles in matter is governed by the laws of chemistry if electromagnetic interactions dominate at atomic distances. Chemical properties of such "quark atoms" can be predicted by interpolating isoelectronic sequences.

Contribution of liquid, NAT and ice particles to chlorine activation and ozone depletion in Antarctic winter and spring [PDF]
Atmospheric Chemistry and Physics, 2015 Heterogeneous reactions in the Antarctic stratosphere are the cause of chlorine activation and ozone depletion, but the relative roles of different types of polar stratospheric clouds (PSCs) in chlorine activation is an open question.

High-fraction brookite films from amorphous precursors
Scientific Reports, 2017 Structure-specific synthesis processes are of key importance to the growth of polymorphic functional compounds such as TiO2, where material properties strongly depend on structure as well as chemistry. The robust growth of the brookite polymorph of TiO2,

The ionization fraction gradient across the Horsehead edge: An archetype for molecular clouds
, 2009 The ionization fraction plays a key role in the chemistry and dynamics of molecular clouds. We study the H13CO+, DCO+ and HOC+ line emission towards the Horsehead, from the shielded core to the UV irradiated cloud edge, i.e., the Photodissociation Region

Global targeting of functional tyrosines using sulfur triazole exchange chemistry
Nature Chemical Biology, 2019 Covalent probes serve as valuable tools for global investigation of protein function and ligand binding capacity. Despite efforts to expand coverage of residues available for chemical proteomics (e.g., cysteine and lysine), a large fraction of the ...
