The Political Economy of Carbon Securities and Environmental Policy [PDF]

open access: yes
The costs of the current suboptimal carbon abatement policy are likely in the range of 3 to 6 trillion 2005 US dollars. Using methods from the political economy of environmental policy, the paper develops a new carbon abatement policy instrument, carbon ...

Transport theory of carbon nanotube Y junctions

open access: yes, 2003
We describe a generalization of Landauer-B\"uttiker theory for networks of interacting metallic carbon nanotubes. We start with symmetric starlike junctions and then extend our approach to asymmetric systems.

C2α‐carbanion‐protonating glutamate discloses tradeoffs between substrate accommodation and reaction rate in actinobacterial 2‐hydroxyacyl‐CoA lyase

open access: yesFEBS Open Bio, EarlyView.
Enzymes of the 2‐hydroxyacyl‐CoA lyase group catalyze the condensation of formyl‐CoA with aldehydes or ketones. Thus, by structural adaptation of active sites, practically any pharmaceutically and industrially important 2‐hydroxyacid could be biotechnologically synthesized. Combining crystal structure analysis, active site mutations and kinetic assays,

Assessment of free-living nitrogen fixing microorganisms for commercial nitrogen fixation [PDF]

open access: yes
Ammonia production by Klebsiella pneumoniae is not economical with present strains and improving nitrogen fixation to its theoretical limits in this organism is not sufficient to achieve economic viability. Because the value of both the hydrogen produced

Cutaneous Melanoma Drives Metabolic Changes in the Aged Bone Marrow Immune Microenvironment

open access: yesAging and Cancer, EarlyView.
Melanoma, the deadliest form of skin cancer, increasingly affects older adults. Our study reveals that melanoma induces changes in iron and lipid levels in the bone marrow, impacting immune cell populations and increasing susceptibility to ferroptosis.

Analyzing the influence of government policy on building carbon emission reduction based on differential game

open access: yesScientific Reports
With the continuous growth of low-carbon economy and people’s increasing preference for low-carbon products, the building carbon emission reduction (CER) has been highly concerned by the government.

Joining of thirty three percent by weight random carbon fibre reinforced low density polyethylene using variable frequency microwave [PDF]

open access: yes, 2003
[Abstract]: This paper extends the range of applications for Variable Frequency Microwave facilities (VFMF) (2 – 18 GHz) to joining thirty three percent by weight carbon fibre reinforced low density polyethylene composite [LDPE/CF (33%)].

From Prestellar to Protostellar Cores II. Time Dependence and Deuterium Fractionation

open access: yes, 2012
We investigate the molecular evolution and D/H abundance ratios that develop as star formation proceeds from a dense-cloud core to a protostellar core, by solving a gas-grain reaction network applied to a 1-D radiative hydrodynamic model with infalling ...

Air Pollution and the Risk and Progression of Multiple Sclerosis: A Systematic Review and Meta‐Analysis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Purpose Air pollution has been linked to several neurological conditions, including stroke and neurodegenerative diseases. Evidence regarding its association with multiple sclerosis (MS) remains conflicting, limited by small sample sizes. Methods PubMed, Embase, Scopus, and Cochrane controlled register of trials (CENTRAL) were searched on ...

Theory and practice of enterprise carbon asset management from the perspective of low-carbon transformation

open access: yesCarbon Management, 2018
Effective carbon asset management is necessary for decreasing carbon resource inputs and reducing carbon emission. Furthermore, carbon asset management is an important measure to realize low-carbon transformation and low-carbon competitiveness for ...
