Anti-scaling agents in kraft pulping

BioResources, 2007
Scale formation in the digester during kraft pulping represents a great problem in pulp mills. Scaling reduces pulping control and efficiency, increasing energy costs and leading to cleaning breakdowns, with subsequent losses in productivity.

It takes a village: Evolving from learning health system to learning community for health equity

Learning Health Systems, EarlyView.
Abstract Introduction Improving health equity requires engagement with partners outside of the clinical health system to address the socio‐political‐economic and structural drivers that shape health equity. Health systems need to focus on learning with communities to impact these conditions.

The Southern California Healthcare Delivery Science Center: A Model for Aligning Patients, Healthcare Systems, and Researchers to Develop, Test, and Disseminate Innovations to Achieve Health Equity

Learning Health Systems, EarlyView.
ABSTRACT Introduction A key barrier to translating evidence into practice is the paucity of learning health system (LHS) researchers elucidating and addressing barriers to implementation and maintenance. Methods In response to the growing need for a workforce dedicated to translating evidence into practice, we developed the Southern California ...

Recent Developments in Sustainable Composites for Printed Circuit Boards (PCBs): A Review

Macromolecular Materials and Engineering, EarlyView.
This review presents the potential of using natural plant fibers and biodegradable polymers as sustainable printed circuit boards (PCBs). This review provides future directions in innovation and sustainable PCBs development. Bio‐composites PCBs are both environmentally friendly and sustainable due to the natural fibres they contain.

Bio‐Based Epoxy Resins from Estragole: Achieving High Glass Transition Temperatures Comparable to DGEBA and Simultaneously Low Viscosities

Macromolecular Materials and Engineering, EarlyView.
Two novel bio‐based epoxy monomers, diglycidyl‐4‐allylphenol (DG‐4A) and triglycidyl‐diallylphenol (TG‐DA), derived from estragole (92% and 72% bio‐content), were synthesized and cured with isophorone diamin (IPDA) and 4,4´‐diaminodiphenyl sulfone (DDS). The resins show high Tgs, with DG‐4A reaching and TG‐DA exceeding DGEBA‐based systems. These resins

Low‐Hysteresis Cellulose‐Based Hydrogels for Strain Detecting

Macromolecular Rapid Communications, EarlyView.
Low‐hysteresis hydrogel with high cellulose content is prepared. The modified cellulose is prepared through a sequential periodate oxidation and borohydride reduction process. The hydrogel can be used as a strain sensor with a gauge factor of 1.1 in the 0%–300% sensing range.

CHARACTERIZATION AND PROPERTIES OF ION EXCHANGERS PRODUCED FROM LIGNIN PRECIPITATED AFTER PEROXYACID PULPING

BioResources, 2008
Pulping of bagasse by one-stage and three-stage peroxyacetic acid was carried out. Characterization of the precipitated lignin from the waste liquor of the pulping process was studied using infrared spec-troscopy.

Asphalted parking lots are environmental filters for multiple propagule dispersal and pollination strategies

Nordic Journal of Botany, EarlyView.
Understanding community assembly for wild species in anthropogenic settings has become increasingly important as biodiversity and ecosystem services are threatened by development pressures. Urban hardscape habitats such as parking lots are widespread, extreme, terrestrial anthropogenic environments that influence plant community assembly by way of ...
