Getting it right: 3D cell cultures for the assessment of photosensitizers for photodynamic therapy
(2015)Core quote “Cancer drug screening is rapidly moving towards the use of 3D cell models. The added complexity of PDT action makes this a conditio sine qua non for the screening of new photosensitizers.” -
GGA+U description of lithium intercalation into anatase TiO2
(2010)We have used density-functional theory [generalized gradient approximation (GGA)] to study lithium intercalation at low concentration into anatase TiO 2. To describe the defect states produced by Li doping a Hubbard " +U ... -
Giant Optical Activity of Quantum Dots, Rods, and Disks with Screw Dislocations
(2015)For centuries mankind has been modifying the optical properties of materials: first, by elaborating the geometry and composition of structures made of materials found in nature, later by structuring the existing materials ... -
Glycosidase activated release of fluorescent 1,8-naphthalimide probes for tumor cell imaging from glycosylated 'pro-probes'
(2016)Glycosylated 4-amino-1,8-naphthalimide derivatives possess a native glycosidic linkage that can be selectively hydrolysed in situ by glycosidase enzymes to release the naphthalimide as a fluorescent imaging or therapeutic ... -
Glycosylated naphthalimides and naphthalimide Tröger's bases as fluorescent aggregation probes for Con A
(2019)Herein we report the synthesis of fluorescent, glycosylated 4-amino-1,8-naphthalimide (Nap) 1, and the related 1,8-naphthalimides Tröger's bases (TBNap) 2 and 3, from 1,8-naphthalic anhydride precursors, the α-mannosides ... -
Gold-supported cerium-doped NiOx catalysts for water oxidation
(2016)The development of high-performance catalysts for the oxygen evolution reaction (OER) is paramount for cost-effective conversion of renewable electricity to fuels and chemicals. Here we report the significant enhancement ... -
The goldilocks electrolyte: examining the performance of iron/nickel oxide thin films as catalysts for electrochemical water splitting in various aqueous NaOH solutions
(2016)A rigorous study of electrodeposited pure and mixed Ni/Fe oxides was performed in three different sodium hydroxide electrolytes with various Fe impurity concentrations (<1 ppb, 5 ppb and 102 ppb). The presence and concentration ... -
The good, the bad, and the ugly ? controlling singlet oxygen through design of photosensitizers and delivery systems for photodynamic therapy.
(2018)Singlet oxygen, although integral to photodynamic therapy, is notoriously uncontrollable, suffers from poor selectivity and has fast decomposition rates in biological media. Across the scientific community, there is a ... -
Grain boundary-mediated nanopores in molybdenum disulfide grown by chemical vapor deposition
(Royal Society of Chemistry, 2017)Molybdenum disulfide (MoS2) is a particularly interesting member of the family of two-dimensional (2D) materials due to its semiconducting and tunable electronic properties. Currently, the most reliable method for obtaining ... -
Graphene and MXene-based transparent conductive electrodes and supercapacitors
