Self‐Assembly of Organic–Inorganic Copolymers Toward Bio‐Inspired Cementitious Composites
Advanced Science, EarlyView.Organic–inorganic copolymerization of calcium silicate hydrate and thioctic acid produces a self‐organized nanocomposite inspired by the disordered collagen–mineral architecture of trabecular bone. The resulting material combines a compressive strength above 300 MPa with intrinsic physical reprocessibility, retaining over 80% of its strength and energy

On the Depolymerization of Actin Filaments [PDF]
, 2012 Actin is one of the most abundant and highly conserved proteins in eukaryotic cells. The globular protein assembles into long filaments, which form a variety of different networks within the cytoskeleton. The dynamic reorganization of these networks - which is pivotal for cell motility, cell adhesion, and cell division - is based on cycles of ...

Advanced Science, EarlyView.A deep learning–driven pipeline mining 246 million protein sequences uncovers AhPETase, an evolutionarily distinct PET hydrolase. Engineered variant AhPETaseM1 degrades post‐consumer PET microplastics under physiological conditions and reverses microplasticinduced cytotoxicity in human lung and colon cells, establishing enzymatic microplastic ...

Depolymerization of Neyveli lignite
, 1997 285-290The depolymerization of -20RL, -30RL, and -36RL Neyveli lignite samples was carried out using phenol and p-toluenesulphonic acid (PTSA). The extractability of the depolymerized products was high in a number of solvents.

Overcoming Drug Resistance by Paclitaxel Resistance in Triple‐Negative Breast Cancer
Advanced Science, EarlyView.In the murine triple‐negative breast cancer (TNBC) model, chemotherapy effectively increases tumor neoantigen burden (TNB). Here, the study constructs a liposomal nanovaccine using antigens derived from in vitro chemotherapy‐treated paclitaxel‐resistant TNBC 4T1 cells.

Active‐Site Photothermal Energy Utilization in PET Depolymerization
Angewandte Chemie, EarlyView.Photothermal catalysis enables efficient PET depolymerization, yet the role of active‐site temperature remains unclear. A catalytic activity reversal between Pd–CNG and PdPOM–CNG is observed under thermal and photothermal conditions. Efficient nanoscale photothermal energy delivery raises active‐site temperature, compensates for lower intrinsic ...
