Prospect for pico-hydropower generation from 3D printed Polyethylene Terephthalate Glycol (PETG) Polymer: A Case Study in Pusu River, Malaysia

Case Studies in Chemical and Environmental Engineering
In Malaysia, rural communities rely on fossil fuel-powered generators for electrification. A small-scale Archimedean Screw Turbine (AST) can be utilized to generate pico-hydropower for potential clean energy generation.

Nonisothermal crystallization behavior, and morphology of poly(trimethylene terephthalate)/polyethylene glycol copolymers

Polymer Testing, 2012
Abstract Poly(trimethylene terephthalate)/polyethylene glycol (PTT/PEG) copolymers, with PEG content ranging from 27.2 to 47.4 wt%, were synthesized by melt copolycondensation. Wide-Angle X-ray diffractometer revealed that all copolymers had the same crystal structure of homo-PTT at room temperature. All copolymers could form ring-banded spherulites,

Translating Biomedical Research to Medical Devices: A Practical Guide and the Arteriovenous Graft Case Study

Advanced NanoBiomed Research, EarlyView.
Despite significant advances, most academic research fails to result in medical products that benefit patients. This guide shares five key steps to help researchers close that gap: set clear goals, test thoroughly, protect ideas, build diverse teams, and partner with industry.

Sulfur-Stabilized High Entropy Oxysulfides Enable Efficient CC Bond Cleavage in Ethylene Glycol Electrooxidation for Sustainable Plastic Upcycling to Formate. [PDF]

ChemSusChem
Room‐temperature synthesis method of high‐entropy oxy‐sulfide (HEOS) is introduced. Compared to high‐entropy oxides (HEO), sulfur incorporation promotes oxygen vacancy stabilization and facilitates CC bond cleavage, improving efficiency of ethylene glycol electrooxidation to formic acid. Lower cell overall voltage enables sustainable plastic upcycling

Aromatic Diester Anolytes for Nonaqueous Redox Flow Batteries

Batteries &Supercaps, EarlyView.
Owing to their extended π‐conjugation 2,2′‐bipyridyl aromatic diesters are stable in singly‐ and doubly‐reduced states. In a redox flow battery a high battery voltage of 2.82 V can be realized and a capacity a capacity retention of 99.5% per cycle for 260 cycles.

Structural integrity of custom-designed additive manufactured prosthetic sockets compared to traditional sockets

Results in Materials
Over the past decades, the number of patients with lower extremity amputation increased world-wide. The increasing rate of patients, particularly in developing countries, has led to limited access to clinics and services for prosthetic and orthotic care.

Chemicals having estrogenic activity can be released from some bisphenol a-free, hard and clear, thermoplastic resins [PDF]

, 2014
Background: Chemicals that have estrogenic activity (EA) can potentially cause adverse health effects in mammals including humans, sometimes at low doses in fetal through juvenile stages with effects detected in adults. Polycarbonate (PC) thermoplastic
