Xenopus Oocyte Patch-Clamp Protocol
CLC-0 (Jentsch et al. 1990) and human CLC-1 (Koch et al. 1992) were expressed in Xenopus oocytes and currents were measured at 18°C 2–5 d after injection using the inside-out configuration of the patch-clamp technique (Hamill et al. 1981) with an EPC-7 amplifier (List) and the acquisition program Pulse (HEKA). Pipettes were pulled from aluminosilicate glass capillaries and had resistances of 1–4 MΩ. Pipettes were coated with Sylgard (Corning Inc.) and fire polished. Data were sampled at 20 or 100 kHz (depending on pulse durations) and filtered at 5 or 10 kHz, respectively, with an eight-pole low-pass Bessel filter. Data analysis was performed using self-written software (Visual C++; Microsoft Corp.) and the SigmaPlot program (Jandel Scientific).
Standard bath (internal) solution contained (mM): 120 NMDG-Cl, 2 MgCl2, 10 HEPES, and 2 EGTA, pH 7.3, while standard extracellular (pipette) solution contained (mM): 100 NMDG-Cl, 5 MgCl2, 10 HEPES, and 2 EGTA, pH 7.3. In the low external chloride solution, 90 mM of NMDG-Cl was replaced with 90 mM of NMDG-glutamate. pH was adjusted with NMDG or HCl to the desired value. Mutant I290M is described in Pusch et al. 1995b. RNA synthesis and oocyte injection were performed as described (Wollnik et al. 1997; Saviane et al. 1999).

Formulation and Characterization of Bioinspired Dental Composites
The experimental composites were prepared using a powder to liquid mass ratio of 5: 1. The monomer phase of all experimental composites contained 72 wt% urethane dimethacrylate (UDMA) (DMG, Hamburg, Germany) and 24 wt% PPGDMA (Polysciences Inc, Hirschberg an der Bergstrasse, Germany). 3 wt% 4-methacryloxyethyl trimellitic anhydride (4-META) (Polysciences Inc, Hirschberg an der Bergstrasse, Germany) was added. This may help bind the monomer phase to amine groups and calcium ions in both the composite and dentin. 1 wt% camphorquinone (CQ) (Polysciences Inc, Hirschberg an der Bergstrasse, Germany) was included as initiator.
The glass fillers consisted of 40 nm silica (Azelis, Hertford, UK) combined with two silane treated aluminosilicate glasses (DMG, Hamburg, Germany) with average diameters of 0.7 μm and 7 μm. The mass ratio of 40 nm: 0.7 μm: 7 μm fillers was 1:3:6 to maximize packing. MCPM (53 μm, batch MCP-B26, HiMed, Old Bethpage, NY, USA), β-TCP (34 μm, batch P292 S, Plasma Biotal, Buxton, UK) and PLS (4700 g/mol, 20–50 μm, batch 09010203, Handary S.A., Brussels, Belgium) were used as received. SEM images of filler particles are provided in Fig 1 in addition to an image of brushite crystals formed by mixing MCPM and β-TCP with water.
Formulation 1 (F1) and 2 (F2) powders contained 89 wt% and 78 wt% glass respectively. F1 powder also contained 5 wt% MCPM, 5 wt% β-TCP, and 1 wt% PLS whilst F2 powder had 10 wt% MCPM, 10 wt% β-TCP, and 2 wt% PLS. The powder and liquid phase were mixed using a planetary mixer (SpeedMixer, DAC 150.1 FVZ, Hauschild Engineering, Germany) at 3500 rpm for 10 s followed by 2000 rpm for 2 min. Qualitative evaluation of consistency and colour of the mixed pastes were examined visually. Two commercially available dental composites were used as controls; Filtek Z250 (Lot number N519660, Shade B3, 3M ESPE, St Paul, MN, USA) and Gradia Direct Posterior (Lot number 1308132, Shade P-A2, GC, Tokyo, Japan).
Disc specimens were prepared using metal circlips (15 or 10 mm internal diameter and 1 mm in thickness) as moulds. The composite pastes were placed in a circlip and covered with acetate sheets on top and bottom sides. They were then light cured by an LED light curing unit (1,100–1,330 mW/cm2, Demi Plus, Kerr, USA) for 40 s with a circular motion on both sides. Specimens were left at room temperature for at least 24 hr to ensure completion of polymerization. After removal from the circlip, any excesses were trimmed. Specimens were then stored in tubes containing 10 cm3 of deionized water or simulated body fluid (SBF) prepared according to BS ISO 23317:2012 [22 ] at 37°C until the required test time.

Cone Photocurrent Recordings Protocol
The cell suspension was immediately deposited on a concanavalin A–coated glass coverslip that formed the transparent bottom of a recording chamber. The chamber was held on the stage of an inverted microscope equipped with differential interference contrast–enhancement optics and operated under IR illumination with the aid of IR-sensitive video cameras and monitors. After 10 min in darkness, the chamber was vigorously perfused with glucose-Ringer’s solution. Single and twin cones lacking their nuclear and synaptic regions (Miller and Korenbrot, 1993 (link)) remained firmly attached to the coverslip. The chamber was intermittently perfused throughout an experimental session, but not at the time photocurrents were measured.
Tight-seal electrodes were fabricated from aluminosilicate capillary glass (1.5 × 1.1 mm; 1724; Corning) and applied onto the side of the cone inner segment. After forming a giga-seal, whole cell mode was attained by sustained suction while holding membrane voltage at 0 mV. Membrane current drifted continuously toward an outward (positive) value. When this drifting ceased (5–15 s; +40 to +70 pA), holding voltage was shifted to −40 mV, where membrane current was near zero. This method yielded more stable recordings than attaining whole cell mode at −40 mV. Voltage-clamped membrane currents were measured with a patch-clamp amplifier (Axopatch 1D; Molecular Devices). Analogue signals were low-pass filtered below 50 Hz with an eight-pole Bessel filter (Frequency Devices) and digitally acquired at 1 KHz (Digidata 1322A and pClamp 9.2; Molecular Devices). All photocurrents reported and analyzed here were measured within 8 min of the moment whole cell mode was achieved.

Aluminosilicate Membranes for Phytochrome Removal
Not available on PMC !
The process begins with the preparation of sodium-excited aluminosilicate ceramic membranes, which are not subjected to a sintering process to maintain their porous structure. These ceramics were first shaped into sheets with a thickness of approximately 2 ± 0.5 mm using a precision diamond wire cutting machine, ensuring uniform thickness across samples for consistent experimental conditions. The slurry for the substrate coating was prepared by mixing metal-organic frameworks (MOFs) and polyvinylpyrrolidone (PVP) in a solvent mixture of ethanol and water at a mass ratio of 3:1. This homogeneous mixture was then evenly coated on the surface of the aluminosilicate substrates to a controlled thickness ranging from 1 to 2.5 mm. The specifics of the slurry ratios and the detailed composition related to aluminosilicate ceramic membranes are tabulated (refer to Table 1), highlighting variations in molar ratios of NaOH/SiO 2 , which are crucial for tailoring the physical properties of the ceramic membranes. After coating, the substrates were air-dried at room temperature to evaporate the solvents effectively, ensuring the formation of a sturdy MOF-PVP composite film on the membrane substrates. The curing of the substrates was performed under wet conditions at 60 • C, which facilitates the formation of a robust composite structure by enhancing the interaction between the ceramic membrane surface and the MOF-PVP coating. The change in chlorophyll concentration was used to calculate the removal efficiency of phytochromes by alkali-excited prepared Fe-MOF/non-firing aluminosilicate membranes. The calculation method is consistent with that previously reported in the literature [44] (link). The chlorophyll adsorption experiments were carried out on samples with different sodium hydroxide contents, different temperatures, different pH levels, different solution amounts, and different coating thicknesses. The absorbance test was carried out in the wavelength range of 200-800 nm using a UV spectrophotometer. Chlorophyll has a strong absorption band at 630-670 nm in the red-light absorption band. The absorption peak of chlorophyll a was at 645 nm and that of chlorophyll b was at 663 nm. The chlorophyll concentration (C c ) and the removal rate of chlorophyll concentration (R%) were calculated as follows:
Chlorophyll concentration (C c ):
Chlorophyll removal (R%):
where A 663 : absorbance of the solution at 663 nm; A 645 : absorbance of the solution at 645 nm; C 0 : initial concentration of phytochromes (mg/L); C e : remaining concentration of phytochromes (mg/L).
Following the official method of the AOAC, phytochromes were extracted from vegetables [49] (link). The phytochromes in the extract were composed of chlorophyll a, chlorophyll b, chlorophyll c, lutein, carotene, etc. We used the change in chlorophyll concentration to calculate the removal efficiency of the prepared composites for phytochromes. Homogenized spinach juice was prepared using 10.0 g of fresh spinach leaves after the removal of surface dust and 200 mL of deionized water. The larger cellulose and impurity particles were removed from the spinach juice using a sieve. Another 40 mL of deionized water was added to 5 mL of spinach juice, which was the stock solution of chlorophyll used in the experiment, in order to make the removal effect more obvious. The treated filtrate was mixed with 10 mL of acetonitrile (containing 1% acetic acid), and the mixture was vortexed in a vortex mixer at 1200 rpm/min for 5 min. 1.0 g of sodium acetate anhydrous and 4.0 g of anhydrous magnesium sulfate were added and the mixture was immediately vortexed for another 2 min. Finally, the organic phase was centrifuged at 9000 rpm for 5 min. The UV-Vis absorption spectra were scanned in the wavelength range of 200-800 nm using the phytochromes solution (organic phase) to obtain the full absorption spectra.

Hierarchical Aluminosilicate Synthesis and Modification
Monodispersed spherical silica (silica) was used (Superior silica, USA). Hierarchical Aluminosilicate (HAS) (SiO2/Al2O3 ratio 80) with micro and meso hexagonal pores was synthesized through top-down approach using nanozeolitic seed and mesoporous template CTAB.34 (link) The parent ZSM-5 (zeolyst) was dissolved in alkaline solution in presence of template and then pH adjusted using dilute sulfuric acid. The material was left for hydrothermal aging for few days and then collected through filtration, washing, drying and calcination steps. The obtained nanomaterial was further modified by refluxing using 3-aminopropyltrimethoxysilane by dispersing in toluene solution. After silane addition, the solution mixture was refluxed for 6 hours under argon atmosphere. Then solution was centrifuged, precipitated sample was washed and dried. The sample was denoted as APTMOS-HAS. For the other sample including silica, a similar refluxing procedure was carried out and denoted as APTMOS-silica.

Synthesis of Ceramic Membranes via Alkali Activation
Not available on PMC !
First, alumina and silica powders were mixed at a molar ratio of 1:1 by mechanical ball milling at 300 rpm for 60 min, with zirconia balls of 5 mm in size and a ball-to-powder ratio of 10:1. The ball mill powder not only performs the homogeneous mixing of the powder, but also activates the surface of the powder, making the reaction required for producing oxide ceramics easier. The mixed powder was processed through a 60-mesh sieve to prevent powder agglomeration during the ball milling process. If the sample contained powder sodium silicate, the powder sodium silicate was mixed with the powder in proportion to the ball mill to ensure the uniformity of the powder.
Sodium hydroxide was dissolved in deionized water, and a sodium activator of pure sodium hydroxide was prepared. Waterglass and powder sodium silicate were added to prepare an activator containing sodium silicate. All alkali activators were then ready for use. The powder, after ball milling, was mixed with alkali activator and stirred for 10 min, and then poured into a mold (ϕ25 mm * 8 mm) to cure and dry in a thermal and humidity test chamber at different times and in different modes. The main factors affecting the properties of ceramic membranes were explored, aiming to obtain the best ratio.

Selective Functionalization of Silsesquioxane Cages
A Schlenk vessel
equipped with a stir bar was sealed, evacuated, weighed, taken into
the drybox, and loaded with (Me3Sn)8Si8O20 (∼2 g, CUBE). Then, the vessel was evacuated
and weighed again to determine the exact masses of the vessel and
the reagent. The vessel was reconnected to the manifold, the solvent
(toluene or THF, 20 cm3) was added by a syringe, and the
resulting solution was cooled to −80 °C. In the case of
compounds L–AlMe3 (L = py, Et3N, TEPO)
and [Me4N] [AlCl4], a weighed 20 cm3 screw-top vial with a PTFE septum was loaded with the corresponding
Al complex (1.5 or 3.0 equiv of the reactive groups per CUBE) in the
drybox, taken out, and weighed and the solvent (5 cm3)
was introduced by a syringe to produce a solution. In the case of
L–AlCl3 (L = THF, py, and TEPO), the ligand and
AlCl3 were loaded into separate weighed vials and the solvent
was first used to dissolve the ligand before it was transferred to
the AlCl3 vial to generate the complex in situ. Care was taken to ensure the ratio of L/Al ≥1 to avoid uncoordinated
AlCl3. The AlCl3 vial was initially cooled by
liquid N2 to dampen the highly exothermic contact of the
ligand with the strong Lewis acid. The room-temperature solution of
an Al complex was then added dropwise to the cooled solution of the
CUBE with vigorous stirring over 10 min. Another portion of the solvent
(5 cm3) was used in several doses to ensure a quantitative
transfer of L–AlCl3. The Schlenk vessel was sealed
and allowed to slowly warm up in the cooling bath to room temperature
over 12–18 h. Fast warm-ups generally lead to the formation
of inhomogeneous precipitates. After 24 h, the solution was heated
at 60/100 °C for another 48 h, at which point a clear to hazy
solution of oligomers was obtained. All volatiles were removed under
dynamic vacuum at 60/100 °C to obtain a glassy residue, which
was broken to powder by a magnetic stirrer and outgassed further for
48 h at 60/100 °C. The evacuated Schlenk vessel was then weighed
and taken into the drybox for product handling. The solids were analyzed
by 1H, 13C, 27Al, 29Si,
and 31P MAS NMR and FTIR spectroscopies, as well as ICP-OES
and N2 adsorption porosimetry. The volatiles were collected
in a Schlenk-type cold trap and analyzed by solution NMR (Supporting Information, Section S2).
The
reactions with compounds L–AlCl3 and [Me4N] [AlCl4] could only be conducted in THF due to their
low solubility in toluene. Moreover, Et3N is incompatible
with THF as a solvent due to observed ligand scrambling; therefore,
this ligand was used only as Et3N–AlMe3 and only in toluene.
The mass lost as the volatile byproducts
was used to calculate
the gravimetric degree of condensation (DCG/%) of the reacting
functional groups DCG(SnMe3) and DCG(AlX), defining the average connectivity at the CUBE and Al, respectively.
Ideally, only a single byproduct would be generated (SnMe4, SnMe3Et, or SnMe3Cl); however additional
SnMe4 was observed in conjunction with each of the expected
byproducts. The excess of SnMe4 will be further linked
to an unexpected formation of [AlO4]− species, and therefore, it is conveniently quantified in mol % with
respect to the Al content as DCG(SnMe4). In
the case of compounds L–AlCl3, L–AlEt3, and [Me4N] [AlCl4], the byproduct
ratio is determined by 1H NMR integration while with L–AlMe3, a full condensation of Al–Me must be assumed in order
to quantify the excess of SnMe4. A full description of
the calculation procedure and the complete characterization data for
all products are provided in the Supporting Information (Sections S2 and S3, respectively).

Optimizing Self-Compacting Concrete with Aluminosilicate SCMs
Previously published research articles on self-compacting concrete (SCC) have significantly influenced the utilization of various supplementary cementitious materials (SCMs), and alternative raw material substitutes. These studies have distinctly explored the developmental stages of SCC, alongside the requisite constituent materials. These investigations have encompassed evaluations of both the plastic and hardened state properties of SCC. Moreover, there is a pressing need to explore into the utilization of high replacement levels (i.e., above 40%) of Metakaolin and limestone powder blends in SCC development, employing Response Surface Method (RSM) optimization techniques, and conducting comparison of different SCMs of varying aluminosilicate percentages. The primary objective of this methodology, as depicted in Fig. 1, is to dissect SCMs rich in aluminosilicate content, crucial for manufacturing SCC.
