The.idea.that.self-care.is.a.primary.obligation.for.mental.health.
professionals.is.an.interesting.notion.that.should.be.addressed..The.
consensus.among.many.mental.health.professionals.is.that.self-care.
is.an.ethical.imperative..Without.caring.for.themselves,.it.is.unlikely.
that. they. will. be. able. to. optimally. care. for. their. clients.. Mental.
health. professionals. involved. in. death. penalty. cases. may. experience.increased.stress.due.to.operating.in.forensic.settings,.having.
to.confront.and.negotiate.their.own.beliefs.and.ethics.regarding.the.
death.penalty,.and.being.confronted.with.the.imminent.execution.of.
their.client(s)..Inmates.receiving.services.from.mental.health.professionals.often.present.with.loneliness,.powerlessness,.hopelessness,.
dehumanization,. demoralization,. tension,. decay,. apathy,. and. psychological.pressure.(Brown.and.Benningfield,.2008)..Mental.health.
professionals.are.ethically.obligated.to.help.their.clients.with.these.
particular. symptoms. while. operating. under. the. realization. of. the.
inevitable.death.of.their.clients..To.ensure.that.mental.health.professionals.are.practicing.at.their.highest.level.of.functioning,.and.are.
not.compromised.by.stress.or.burnout,.they.should.be.encouraged.
to.monitor.four.dimensions.of.health:.physical,.mental,.emotional,.
and.spiritual..Subjective.and.objective.methods.that.mental.health.
professionals. can. use. to. self-evaluate. their. level. of. health. while.
working.in.death.penalty.cases.will.be.explored.in.this.presentation.

The. electronic. properties. of. nanoscale. conductors. are. very.
sensitive.to.their.environment,.and.this.property.has.led.to.a.decadelong.investigation.of.potential.chemical.sensor.and.biosensor.applications..Single.walled.carbon.nanotubes.(SWCNTs).are.particularly.
appealing.elements.because.they.are.hollow.conductors.with.all.of.
their. conduction. electrons. on. the. exposed. surface.. Recently,. we.
have.demonstrated.single.molecule.dynamic.sensitivity.using.field.
effect.transistors.made.out.of.individual.SWCNTs.(1)..
Similar. devices. have. now. been. applied. to. the. problem. of.

sensing. protein. dynamics. in. physiologically-relevant. solutions..
Our.work.focuses.on.the.dynamics.of.the.lysozyme.enzyme..By.
attaching.a.lysozyme.to.a.SWCNT.device,.we.have.accomplished.
real-time. monitoring. of. lysozyme’s. single. molecule. dynamics..
Electronic.monitoring.with.a.temporal.resolution.of.10.microseconds.occurs.as.the.mechanical.motions.of.the.protein.cause.changes.in.the.conductance.of.the.SWCNT..Acquisition.times.can.be.continued.for.tens.of.minutes,.allowing.for.the.investigation.of.a.single.
protein.over.a.wide.range.of.time.scales..This.data.helps.to.address.
uncertainty. concerning. the. mechanism. of. lysozyme’s. enzymatic.
turnover.. Analysis. of. the. changes. in. conductance. show. various.
Poisson.processes.that.may.be.related.to.the.hinge.motion.of.the.
lysozyme. molecule. during. non-catalytic. and. catalytic. binding. of.

This. presentation. describes. a. novel. type. of. scanning. probe.
characterization. called. scanning. gate. spectroscopy. (SGS).. Our.
method.is.based.upon.scanning.gate.microscopy,.a.technique.for.
characterizing.the.electronic.properties.of.a.surface.and,.in.particular,.
of. electronic. devices.. Scanning. gate. microscopy. has. proven.
very.important.for.understand.nanomaterials.and.how.they.might.
be.used.in.circuits..
In. the. new. SGS. technique,. we. have. extended. the. usefulness.
of.scanning.gate.microscopy.by.acquiring.images.using.a.continuous.range.of.probe.potentials..The.result.captures.not.just.a.surface.image,.but.also.the.energy.dependence.of.scattering.sites,.boundaries,.and.other.electronic.surface.features..As.an.example,.we.investigate.resistance.along.a.single-walled.carbon.nanotube.(SWCNT)..
SGS.clearly.observes.the.individual.sites.that.contribute.most.to.a.
SWCNT.resistance,.including.defects.or.chemical.attachments.that.
are.not.visible.topographically..Furthermore,.SGS.directly.resolves.
the.energy.spectrum.of.electronic.scattering.at.a.defect.site.and.allows.
us.to.extract.the.effective.barrier.width.and.heights.of.such.features.

Nanoscale.devices.traditionally.rely.on.external.voltage.sources.
for. power,. e.g.,. batteries,. fuel. cells,. power. supplies.. In. principle,.
however,.electric.potentials.and.fields.at.the.microscale.can.be.established.between.dissimilar.metals.and.semiconductors.via.the.dissimilar.chemical.potentials.of.their.mobile.charge.carriers..These.endogenous.
potentials. and. fields. can. be. sustained. indefinitely. without.
power.consumption.and.can.regenerate.quickly.at.system.boundaries..It.has.been.proposed.that.these.fields.can.lead.to.challenges.to.the.
second.law.when.incorporated.in.MEMS.and.NEMS.devices.[1,2]..A.
decade-long.objection.to.these.challenges.has.been.that.endogenous.
fields.have.not.been.experimentally.measured..This.paper.details.the.
experimental.verification.of.the.magnitudes.and.locations.of.these.
predicted.fields,.using.scanning.Kelvin.probe.microscopy.
