Engineered immunostimulatory H2O2‐producing microreactors driven by yeast as localized living cancer therapeutics

open access: yesBMEMat, EarlyView.
Engineered yeast microreactors that produce H2O2 within tumors enable selective cancer cell killing while releasing immunostimulatory components, effectively suppressing local tumor growth and activating systemic antitumor immunity, with further efficacy enhanced by anti‐PD‐1 therapy and transarterial embolization.

Improving the Mechanical Properties of Biodegradable Polyhydroxyalkanoates via PHA–PHA Block‐Copolymer Synthesis

open access: yesChemistry – A European Journal, EarlyView.
Covalent linkage of a highly crystalline PHBV with a ductile P3HB4HB is shown to produce block copolymers with markedly enhanced extensibility and toughness, outperforming equivalent blends. The results demonstrate that polymer architecture, not composition alone, governs mechanical response, offering a route to biodegradable materials that combine ...

Cyclization of a 1,8‐Diphenylanthracene by Scholl Reactions to Form Five‐ and Seven‐Membered Ring Embedded Polycyclic Aromatic Hydrocarbons

open access: yesChemistry – A European Journal, EarlyView.
Reactions of 10‐mesityl‐1,8‐diphenylanthracene with DDQ/TfOH produced three products via sequential formation of a five‐ or seven‐membered ring. Unexpectedly, the triply cyclized product with a rubicene substructure was formed through cyclization involving 1,2‐methyl shift.

Review of Hmong and American: From Refugees to Citizens [PDF]

open access: yesHmong Studies Journal, 2012
While much research has been done on the Hmong, few studies have focused specifically on Hmong American identity. Vincent K. Her’s and Mary Louise Buley-Meissner’s Hmong and American is a contribution to this area of Hmong Studies as contributors to this

Partially Biobased Polyurethanes With Reversibly Crosslinkable Furan Units Toward Recyclable Thermosetting Textile Fibres

open access: yesChemistry – A European Journal, EarlyView.
A molecular design strategy combines lignin‐derived aromatic units, sugar‐derived furan groups, and flexible glycol segments to create wet‐spinnable polyurethanes. Thermally reversible Diels–Alder crosslinking chemistry enables formation of crosslinked thermosetting fibers, repeated de‐crosslinking/re‐crosslinking cycles, and tunable fiber properties ...

Heterologous expression of lipase gene (lip) and PHA synthase gene (PHAC1) from pseudomonas spp. in escherichia coli for the biosynthesis of polyhydroxyalkanoates (PHA) / Aung Shuh Wen [PDF]

open access: yes, 2011
Polyhydroxyalkanoates (PHA) are natural biodegradable and biocompatible plastic materials which potentially have a wide range of applications. The potential commercial value of these polyesters prompts a demand for intensive studies to maximise their ...

Proximal Steric Shielding Unlocks High Solid‐State Luminescence in Quinoxaline‐Fused Pyrene Heteroacenes

open access: yesChemistry – A European Journal, EarlyView.
Proximal steric tuning of quinoxaline‐fused pyrene heteroacenes enables soluble derivatives that exhibit solid‐state photoluminescence quantum yields (PLQYs) up to 82%, surpassing previous benchmarks. This work reveals key structure–property relationships for next‐generation, processable organic emitters in advanced optoelectronic applications ...

Waste activated sludge high‐rate treatment of septage: Stabilization phase trials and comparison with winery wastewater treatment

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Performance evaluation of the waste activated sludge high‐rate (WASHR) process for septic wastewater treatment. Abstract The waste‐activated sludge high‐rate (WASHR) process is evaluated as a batch‐mode pre‐treatment for actual septage using a high‐rate contact stabilization (HRCS) approach.

Production and optimisation of Polyhydroxyalkanoates (PHA) from Bacillus subtilis using response surface methodology [PDF]

open access: yesNetwork Biology
Polyhydroxyalkanoates (PHAs) are storage materials, accumulated by various bacteria as energy and carbon reserve materials. They are biodegradable and biocompatible; hence, they can be used in packaging and carrier molecules in the agricultural field. In
