abstract = {Light-responsive microactuators composed of vertically aligned carbon 

 nanotube (CNT) forests mixed with poly(N-isopropylacrylamide) (PNIPAM) 

 hydrogel composites are studied. The benefit of this composite is that 

 CNTs act as a black absorber to efficiently capture radiative heating 

 and trigger PNIPAM contraction. In addition, CNT forests can be 

 patterned accurately using lithography to span structures ranging from a 

 few micrometers to several millimeters in size, and these CNT-PNIPAM 

 composites can achieve response times as fast as 15 ms. The kinetics of 

 these microactuators are investigated through detailed analysis of 

 high-speed videos. These are compared to a theoretical model for the 

 deswelling dynamics, which combines thermal convection and polymer 

 diffusion, and shows that polymer diffusion is the rate-limiting factor 

 in this system. Applications of such CNT/hydrogel actuators as 

 microswimmers are discussed, with light-actuating micro-jellyfish 

 designs exemplified, and >1500 cycles demonstrated.},

abstract = {Spin qubits in gate-defined silicon quantum dots are receiving increased 

 attention thanks to their potential for large-scale quantum computing. 

 Readout of such spin qubits is done most accurately and scalably via 

 Pauli spin blockade (PSB), however, various mechanisms may lift PSB and 

 complicate readout. In this work, we present an experimental study of 

 PSB in a multi-electron low-symmetry double quantum dot (DQD) in silicon 

 nanowires. We report on the observation of non-symmetric PSB, 

 manifesting as blockaded tunneling when the spin is projected to one QD 

 of the pair but as allowed tunneling when the projection is done into 

 the other. By analyzing the interaction of the DQD with a readout 

 resonator, we find that PSB lifting is caused by a large coupling 

 between the different electron spin manifolds of 7.90 mu eV and that 

 tunneling is incoherent. Further, magnetospectroscopy of the DQD in 16 

 charge configurations, enables reconstructing the energy spectrum of the 

 DQD and reveals the lifting mechanism is energy-level selective. Our 

 results indicate enhanced spin-orbit coupling which may enable 

 all-electrical qubit control of electron spins in silicon nanowires.},

abstract = {The adverse environmental impacts of greenhouse gas emissions and 

 persistent waste accumulation are driving the demand for sustainable 

 approaches to clean-energy production and waste recycling. By coupling 

 the thermodynamically favourable oxidation of waste-derived organic 

 carbon streams with fuel-forming reduction reactions suitable for 

 producing clean hydrogen or converting CO2 to fuels, solar reforming 

 simultaneously valorizes waste and generates useful chemical products. 

 With appropriate light harvesting, catalyst design, device 

 configurations and waste pre-treatment strategies, a range of 

 sustainable fuels and value-added chemicals can already be selectively 

 produced from diverse waste feedstocks, including biomass and plastics, 

 demonstrating the potential of solar-powered upcycling plants. This 

 Review highlights solar reforming as an emerging technology that is 

 currently transitioning from fundamental research towards practical 

 application. We investigate the chemistry and compatibility of waste 

 pre-treatment, introduce process classifications, explore the mechanisms 

 of different solar reforming technologies, and suggest appropriate 

 concepts, metrics and pathways for various deployment scenarios in a 

 net-zero-carbon future.

abstract = {Polarized light is critical for a wide range of applications, but is 

 usually generated by filtering unpolarized light, which leads to 

 substantial energy losses and requires additional optics. Here we 

 demonstrate the direct emission of linearly polarized light from 

 light-emitting diodes made of CsPbI3 perovskite nanoplatelet 

 superlattices. The use of solvents with different vapour pressures 

 enables the self-assembly of the nanoplatelets with fine control over 

 their orientation (either face-up or edge-up) and therefore their 

 transition dipole moment. As a result of the highly uniform alignment of 

 the nanoplatelets, as well as their strong quantum and dielectric 

 confinement, large exciton fine-structure splitting is achieved at the 

 film level, leading to pure red light-emitting diodes with linearly 

 polarized electroluminescence exhibiting a high degree of polarization 

 of 74.4% without any photonic structures. This work demonstrates the 

 potential of perovskite nanoplatelets as a promising source of linearly 

 polarized light, opening up the development of next-generation 

 three-dimensional displays and optical communications from a highly 

 versatile, solution-processable system. 

 Self-assembled perovskite nanoplatelets emit linearly polarized light,

abstract = {The lithium-air battery (LAB) is arguably the battery with the highest 

 energy density, but also a battery with significant challenges to be 

 overcome before it can be used commercially in practical devices. Here, 

 we discuss experimental approaches developed by some of the authors to 

 understand the function and failure of lithium-oxygen batteries. For 

 example, experiments in which nuclear magnetic resonance (NMR) 

 spectroscopy was used to quantify dissolved oxygen concentrations and 

 diffusivity are described. 17O magic angle spinning (MAS) NMR spectra of 

 electrodes extracted from batteries at different states of charge (SOC) 

 allowed the electrolyte decomposition products at each stage to be 

 determined. For instance, the formation of Li2CO3 and LiOH in a 

 dimethoxyethane (DME) solvent and their subsequent removal on charging 

 was followed. Redox mediators have been used to chemically reduce oxygen 

 or to chemically oxidise Li2O2 in order to prevent electrode clogging by 

 insulating compounds, which leads to lower capacities and rapid 

 degradation; the studies of these mediators represent an area where NMR 

 and electron paramagnetic resonance (EPR) studies could play a role in 

 unravelling reaction mechanisms. Finally, recently developed coupled in 

 situ NMR and electrochemical impedance spectroscopy (EIS) are used to 

 characterise the charge transport mechanism in lithium symmetric cells 

 and to distinguish between electronic and ionic transport, demonstrating 

 the formation of transient (soft) shorts in common lithium-oxygen 

 electrolytes. More stable solid electrolyte interphases are formed under 

 an oxygen atmosphere, which helps stabilise the lithium anode on 

 cycling.

 Alternative therapeutics to combat the rise in drug-resistant strains of 

 bacteria and fungi are thus needed, but the development of new classes 

 of small molecule therapeutics has remained challenging. Here, we 

 explore an orthogonal approach and address this issue by synthesising 

 micro-scale, protein colloidal particles that possess potent 

 antimicrobial properties. We describe an approach for forming silk-based 

 microgels that contain selenium nanoparticles embedded within the 

 protein scaffold. We demonstrate that these materials have both 

 antibacterial and antifungal properties while, crucially, also remaining 

 highly biocompatible with mammalian cell lines. By combing the 

 nanoparticles with silk, the protein microgel is able to fulfill two 

 critical functions; it protects the mammalian cells from the cytotoxic 

 effects of the bare nanoparticles, while simultaneously serving as a 

 carrier for microbial eradication. Furthermore, since the antimicrobial 

 activity originates from physical contact, bacteria and fungi are 

 unlikely to develop resistance to our hybrid biomaterials, which remains 

 a critical issue with current antibiotic and antifungal treatments. 

 Therefore, taken together, these results provide the basis for 

 innovative antimicrobial materials that can target drug-resistant 

 microbial infections.

 To decrease their energy and materials usage, a key quest is to 

 miniaturise lasers down to nanocavities. Obtaining the smallest mode 

 volumes demands plasmonic nanocavities, but for these, gain comes from 

 only a single or few emitters. Until now, lasing in such devices was 

 unobtainable due to low gain and high cavity losses. Here, we 

 demonstrate a form of `few emitter lasing' in a plasmonic nanocavity 

 approaching the single-molecule emitter regime. The few-emitter lasing 

 transition significantly broadens, and depends on the number of 

 molecules and their individual locations. We show this non-standard 

 few-emitter lasing can be understood by developing a theoretical 

 approach extending previous weak-coupling theories. Our work paves the 

 way for developing nanolaser applications as well as fundamental studies 

 at the limit of few emitters.},

 have immense potential in microrobotics, haptics, and biomedical 

 applications. However, the fabrication of miniaturized and 

 micropatterned open-air soft actuators has remained challenging. In this 

 study, we demonstrate the microfabrication of trilayer electrochemical 

 actuators (ECAs) through aerosol jet printing (AJP), a rapid prototyping 

 method with a 10 mu m lateral resolution. We make fully printed 1000 x 

 5000 x 12 mu m(3) ultrathin ECAs, each of which comprises a Nafion 

 electrolyte layer sandwiched between two 

 poly-(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) 

 electrode layers. The ECAs actuate due to the electric-field-driven 

 migration of hydrated protons. Due to the thinness that gives rise to a 

 low proton transport length and a low flexural rigidity, the printed 

 ECAs can operate under low voltages (similar to 0.5 V) and have a 

 relatively fast response (similar to seconds). We print all the 

 components of an actuator that consists of two individually controlled 

 submillimeter segments and demonstrate its multimodal actuation. The 

 convenience, versatility, rapidity, and low cost of our microfabrication

abstract = {Chiral plasmonic nanoparticles have attracted much attention because of 

 their strong chiroptical responses and broad scientific applications. 

 However, the types of chiral plasmonic nanoparticles have remained 

 limited. Herein we report on a new type of chiral nanoparticle, chiral 

 Au nanorod (NR) with five-fold rotational symmetry, which is synthesized 

 using chiral molecules. Three different types of Au seeds (Au elongated 

 nanodecahedrons, nanodecahedrons, and nanobipyramids) are used to study 

 the growth behaviors. Different synthesis parameters, including the 

 chiral molecules, surfactant, reductant, seeds, and Au precursor, are 

 systematically varied to optimize the chiroptical responses of the 

 chiral Au NRs. The chiral scattering measurements on the individual 

 chiral Au NRs and their dimers are performed. Intriguingly, the 

 chiroptical signals of the individual chiral Au NRs and their end-to-end 

 dimers are similar, while those of the side-by-side dimers are largely 

 reduced. Theoretical calculations and numerical simulations reveal that 

 the different chiroptical responses of the chiral NR dimers are 

 originated from the coupling effect between the plasmon resonance modes. 

 Our study enriches chiral plasmonic nanoparticles and provides valuable 

 insight for the design of plasmonic nanostructures with desired 

 chiroptical properties. 

 The scattering dissymmetry factor (gs-factor) peaks of the horizontal 

 chiral Au nanorods are redshifted with higher intensities compared to 

 those of the vertical chiral Au nanorods. The intensity of the chiral 

 response of the side-by-side chiral nanorod dimers is reduced because of 

 the coupling between the plasmon resonance modes.image},
