Unlocking high-performance photocapacitors for edge computing in low-light environments
Unlocking high-performance photocapacitors for edge computing in low-light environments† Driving continuous, low-power artificial intelligence (AI) in the Internet of Things (IoT) requires reliable energy harvesting and storage under indoor or low-light conditions, where batteries face constraints such as finite lifetimes and increased environmental impact.
Investigating the effect of hydrothermal carbonisation reaction times on the photoluminescence of bio-oil-derived carbon polymer dots
Investigating the effect of hydrothermal carbonisation reaction times on the photoluminescence of bio-oil-derived carbon polymer dots† Carbon dots (CDs) have favourable properties such as broad spectral absorption, strong photoluminescence, low toxicity, and high specific surface area.
A lot to unpack: a decade in high Z′ crystal structures
A lot to unpack: a decade in high Z′ crystal structures† Crystal structures that form with more than one molecule in the asymmetric unit (Z′ > 1) are a fascinating and important, if overlooked, aspect of crystal engineering. With the recent publication of the results of the ‘seventh blind test of crystal structure prediction’ the challenges that these structures present and the questions they provoke for the prediction and design of crystalline solids are brought sharply into focus.
Unlocking nature's antioxidants: a novel method for synthesising plasmalogens
Unlocking nature's antioxidants: a novel method for synthesising plasmalogens† Plasmalogens are glycerophospholipids distinguished by their O-(Z)-vinyl ether at the sn-1 position. These lipids are implicated in several disease states requiring analytical, diagnostic and therapeutic interventions, which demand synthetic availability for a variety of structural types.
action of coenzyme B12-dependent diol dehydratase on 3,3,3-trifluoro-1,2-propanediol results in elimination of all the fluorides with formation of acetaldehyde | The Journal of Biochemistry | Oxford Academic
3,3,3-Trifluoro-1,2-propanediol undergoes complete defluorination in two distinct steps: first, the conversion into 3,3,3-trifluoropropionaldehyde catalyzed by adenosylcobalamin (coenzyme B )-dependent diol dehydratase; second, non-enzymatic elimination of all three fluorides from this aldehyde to afford malonic semialdehyde (3-oxopropanoic acid), which is decarboxylated to acetaldehyde.

Crystals in the community and the classroom
Crystallography is just over a century old; it underpins many of the greatest discoveries of the 21st century and is directly responsible for 29 Nobel Prizes to date. It explains why water freezes, why chocolate melts on the tongue, why a drug like thalidomide can be both lifesaving and lethal, and why cement cracks in pavements; and yet it is usually omitted from secondary school curricula (Kantardjieff et al., 2010) and is quickly disappearing from undergraduate courses around the world.
Deducing the conformational space for an octa-proline helix
Deducing the conformational space for an octa-proline helix†‡ A molecular dyad, PY-P8-PER, comprising a proline octamer sandwiched between pyrene and perylene terminals has been synthesized in order to address the dynamics of electronic energy transfer (EET) along the oligo-proline chain. A simple pyrene-based control compound equipped with a bis-proline attachment serves as a reference for spectroscopic studies.
1,4-Dimethoxynaphthalene-2-methyl (‘DIMON’), an oxidatively labile protecting group for synthesis of polyunsaturated lipids
1,4-Dimethoxynaphthalene-2-methyl (‘DIMON’), an oxidatively labile protecting group for synthesis of polyunsaturated lipids† A new benzyl-type protecting group (1,4-dimethoxynaphthalene-2-methyl, ‘DIMON’) for hydroxyl functions can be selectively removed under oxidative conditions without damaging polyunsaturated fatty acyl groups. Its application is shown by the first synthesis of an ether (plasmanyl) phospholipid containing the docosa-(4Z,7Z,10Z,13Z,16Z,19Z)-hexaenoyl group.
Amine-modified polyionic liquid supports enhance the efficacy of PdNPs for the catalytic hydrogenation of CO2 to formate
Amine-modified polyionic liquid supports enhance the efficacy of PdNPs for the catalytic hydrogenation of CO2 to formate† Palladium nanoparticles stabilised by aniline modified polymer immobilised ionic liquid is a remarkably active catalyst for the hydrogenation of CO2 to formate; the initial TOF of 500 h−1 is markedly higher than either unmodified catalyst or its benzylamine and N,N-dimethylaniline modified counterparts and is among the highest to be reported for a PdNP-based catalyst.
Decarbonising electrical grids using photovoltaics with enhanced capacity factors
Decarbonising electrical grids using photovoltaics with enhanced capacity factors† Many scenarios for Net Zero anticipate substantial growth of Solar PV generation to satisfy 30% of our electricity needs. However, this scale of deployment introduces challenges as supply may not meet demand, thereby necessitating energy storage and demand-side management.
Fragment expansion with NUDELs - poised DNA-encoded libraries
Fragment expansion with NUDELs – poised DNA-encoded libraries† Optimisation of the affinity of lead compounds is a critical challenge in the identification of drug candidates and chemical probes and is a process that takes many years. Fragment-based drug discovery has become established as one of the methods of choice for drug discovery starting with small, low affinity compounds. Due to their low affinity, the evolution of fragments to desirable levels of affinity is often a key challenge.
Emerging indoor photovoltaics for self-powered and self-aware IoT towards sustainable energy management
Emerging indoor photovoltaics for self-powered and self-aware IoT towards sustainable energy management† Hannes Michaels, ‡a Michael Rinderle, ‡b Iacopo Benesperi, a Richard Freitag,bc Alessio Gagliardib and Marina Freitag *a Abstract As the number of Internet of Things devices is rapidly increasing, there is an urgent need for sustainable and efficient energy sources and management practices in ambient environments.

A diarsagermylene and a diarsastannylene stabilised by arene⋯Ge/Sn interactions
The synthesis and structures of two new diarsatetrylenes {(Dipp)2As}2E are presented [E = Ge, Sn; Dipp = 2,6-diisopropylphenyl]. The high barrier to planarisation of As prevents stabilisation by As–E ?-interactions; however, arene?Ge/Sn interactions stabilise these compounds by up to 181.4 kJ mol?1. This represents a new stabilisation mode for this class of compounds.
Desolvation and aggregation of sterically demanding alkali metal diarylphosphides
The reaction between (Dipp) PH and one equivalent of n-BuLi, PhCH Na or PhCH K in THF gives the complexes [(Dipp) P]Li(THF) (2a), {[(Dipp) P]Na(THF) } (3a) and [(Dipp) P]K(THF) (4a), respectively [Dipp = 2,6-iPr C H ]. Exposure of these compounds to vacuum yields the alternative solvates [(Dipp) P]Li(THF) (2b), [(Dipp) P]Na(THF) (3b), and [(Dipp) P]K (4b), respectively; the alternative adduct [(Dipp) P]Na(PMDETA) (3c) was prepared by treatment of 3a with PMDETA.
Bridgehead isomer effects in bis(phosphido)-bridged diiron hexacarbonyl proton reduction electrocatalysts
The influence of the substitution, orientation and structure of the phosphido bridges in [Fe (CO) (?-PR ) ] electrocatalysts of proton reduction has been studied. The isomers e,a-[Fe (CO) {?-P(Ar)H} ] (1a(Ar): Ar = Ph, 2?-methoxy-1,1?-binaphthyl (bn?)), e,e-[Fe (CO) {?-P(Ar)H} ] (1b(Ar): Ar = Ph, bn?) were isolated from reactions of iron pentacarbonyl and the corresponding primary phosphine, syntheses that also afforded the phosphinidene-capped tri-iron clusters, [Fe (CO) (?-CO)(?
