Drop‐Location‐Insensitive Droplet‐Based Electricity Generator Using Polydimethylsiloxane Slippery Covalently Attached Liquid Coatings

open access: yesAdvanced Science, EarlyView.
Drop‐location sensitivity remains a key barrier to practical droplet‐based electricity generators (DEGs). Here, a polydimethylsiloxane slippery covalently attached liquid (PDMS‐SCAL)‐coated interface promotes droplet sliding instead of splitting or bouncing, allowing stable electricity generation from randomly falling raindrops. The resulting PDMS‐SCAL‐

Calculation of the Isobaric Heat Capacities of the Liquid and Solid Phase of Organic Compounds at and around 298.15 K Based on Their “True” Molecular Volume

open access: yesMolecules, 2019
A universally applicable method for the prediction of the isobaric heat capacities of the liquid and solid phase of molecules at 298.15 K is presented, derived from their “true„ volume.

Bypassing Heteronuclear MRI: Metal‐Free Organosilicon Nanotracers for Background‐Free Hotspot 1H Imaging on Clinical Hardware

open access: yesAdvanced Science, EarlyView.
Organosilicon micelles enable background‐free molecular magnetic resonance imaging (MRI) while remaining fully compatible with standard proton (1H) hardware. By exploiting a spectrally silent 1H window at ∼0 ppm, the silicone nanotracer allows hotspot detection by 1H chemical‐shift imaging (CSI) without metals or heteronuclei, enabling direct overlay ...

Performance of Siloxane Mixtures in a High-Temperature Organic Rankine Cycle Considering the Heat Transfer Characteristics during Evaporation

open access: yesEnergies, 2014
The application of the Organic Rankine Cycle to high temperature heat sources is investigated on the case study of waste heat recovery from a selected biogas plant. Two different modes of operation are distinguished: pure electric power and combined heat

SigmaFormer: Augmenting transformer encoders with COSMO sigma profiles for pure component property prediction

open access: yesAIChE Journal, EarlyView.
Abstract Transformer‐based molecular models pretrained on SMILES strings demonstrate strong performance in property prediction. However, these model often lack explicit integration of molecular surface charge distributions that govern intermolecular interactions such as hydrogen bonding and polarity.

Hydrogen Permeability of Tubular Polymer Membranes for Biological Methanation Membrane Reactors

open access: yesJournal of Applied Polymer Science, EarlyView.
A reproducible method for permeability measurements of tubular polymer membranes is developed and combined with a comprehensive review of hydrogen permeability data. Based on this analysis, a suitable tubular polymer membrane is identified for application in biological methanation within membrane reactors.

The roles of side chains in Y6‐series non‐fullerene acceptors for high‐performance organic solar cells

open access: yesBulletin of the Korean Chemical Society, EarlyView.
The development of organic solar cells (OSCs) has been driven by structural modifications of Y6‐series non‐fullerene acceptors. In particular, side‐chain engineering regulates solubility, molecular packing, and energy levels, enabling efficiencies to increase from 15.7% to over 20%.

Shape‐directed formation of T8/T6 Zn–siloxane clusters and their deep‐UV shielding properties

open access: yesBulletin of the Korean Chemical Society, EarlyView.
The shape and conformational characteristics of silane substituents direct the assembly of Zn–siloxane clusters into conventional T8 or rare T6 siloxane frameworks. Non‐planar cyclic substituents selectively promote T6 formation through steric effects, while the resulting clusters exhibit deep‐ultraviolet absorption and can be processed into ...

Substituent‐Dependent Structural Trends in Thermal Condensation of Silanetriols and Disiloxanetetraols

open access: yesChemistry – A European Journal, EarlyView.
We report a catalyst‐ and solvent‐free thermal condensation route to oligosilsesquioxanes from arylsilanetriols and disiloxanetetraols. Phenyl and 1‐naphthyl systems form ladder‐like structures, while 2‐naphthyl systems yields layered architectures.
